Subtract dates in Linux

This is working for Linux
main idea find the seconds since "00:00:00 1970-01-01 UTC"
then subtract them. This is GNU extension.

$ a=$(date -d "Tue Apr 29 14:02:19 PDT 2003" +%s)
$ b=$(date -d "Tue Apr 05 14:02:19 PDT 2003" +%s)
$ d=$(( $a - $b ))
$ echo $(( $d / 3600 / 24 ))

Use a PAE enabled kernel

If server has 4 GB or more memory, some operating systems may not access all of the memory. 64 bit OS are out of this subject.
Some PCI, PCI-X and PCI-Express cards use memory below 4 GB which known as PCI hole or PCI Extended Configuration Space. This space could not allocated for system memory and relocated above 4 GB. Then if the operating system is not PAE enabled or not allowed to because of limitation (like Windows Standart edition) could not use this memory location and shows less then 4 GB.

For Windows edition you can add /PAE switch to the boot.ini. (not for XP and standart edition)
For Linux
I confused, because kernel-smp (2.6) versions say that it is supporting up to 16 GB.
But You have to install bigsmp kernel instead of smp for SUSE. And i686-smp or hugemem kernels for Red Hat. (kernel-hugemem is required for memory configurations higher than 16 GB).
There is kernel-pae packeges for some distributions(Fedora, CentOS).

You can find warning message "Use a PAE enabled kernel" from output of dmesg command.
BTW There is another option that you can compile your kernel.

Zenoss Installation Fedora 7

Zenoss requires older version of python. But Fedora 7 or later comes with newer version.

Mysql installation
------
Mysql packages
mysql-devel-5.0.37-2.fc7.i386.rpm
mysql-libs-5.0.37-2.fc7.i386.rpm
mysql-5.0.37-2.fc7.i386.rpm
perl-DBI-1.53-2.fc7.i386.rpm
mysql-server-5.0.37-2.fc7.i386.rpm
perl-DBD-MySQL-3.0008-1.fc7.i386.rpm

# chkconfig mysqld on
# service mysqld start

Give password for mysql
# /usr/bin/mysqladmin -u root password pass

Some other packages you need:
make-3.81-6.fc7
swig-1.3.31-0.fc7
autoconf-2.61-8.fc7

python installation
------
You need older version of python (2.4) for zenoss installation. You can compile and install to another path

# mkdir /opt/python/python2.4.4
# ./configure --prefix=/opt/python/python2.4.4
# make
# make install
# cd /usr/local/bin
# ln -s /opt/python/python2.4.4/bin/python
# ln -s /opt/python/python2.4.4/bin/python2.4



zenoss installation
------
# useradd zenoss
# cat /etc/passwd | grep zenoss


edit profile
cd /home/zenoss
vi .bashrc
export ZENHOME=/usr/local/zenoss
export PYTHONPATH=$ZENHOME/lib/python
export PATH=$ZENHOME/bin:$PATH

# mkdir /usr/local/zenoss
# chown zenoss /usr/local/zenoss

$ tar xvf zenoss-2.1.3.tar.gz
$ cd zenoss-2.1.3
$ ./install.sh


I got this error
AttributeError: /usr/local/zenoss/bin/python: undefined symbol: netsnmp_get_version

Solve this with installing packages below

Install Linux from disk

I do not have DVD drive so I installed Linux from iso file.

Copy files
mount -o loop openSUSE-10.2-GM-DVD-i386.iso opensuse
cd opensuse
cp linux /boot/inst-linux
cp initrd /boot/inst-initrd

Edit /boot/grub/grub.conf
title Install SUSE
root (hd0,0)
kernel /boot/inst-linux
initrd /boot/inst-initrd

Drives and partitions start from 0. If your have boot filesystem as a partition change the lines "kernel inst-linux" and "initrd inst-initrd"

During installation first you choose disk then you have to type the directory and complete filename of the ISO file.

Ip configuration files for Solaris

Create related configuration file. e1000g? are network interfaces you can find for your host via ifconfig -a
ls /etc/hostname.*
/etc/hostname.e1000g0
/etc/hostname.e1000g1
/etc/hostname.e1000g2


Entries in these files
cat hostname.e1000g0
hstnameloc

cat hostname.e1000g1
hstnamesec

cat hostname.e1000g2
hstnamereal


You have to put ip adress to hostname
cat /etc/hosts
10.210.50.69 hstnamereal loghost
192.168.20.6 hstnamesec
192.168.25.6 hstnameloc

Also to netmaks
cat /etc/netmasks
192.168.20.0 255.255.255.0
192.168.25.0 255.255.255.0
10.210.50.0 255.255.255.0

You can configure nodename which you see at the command prompt
cat /etc/nodename
hstnamereal



Virtual interface
cat /etc/hostname.e1000g0:1
hstnamevirtual

add /etc/hosts
10.210.50.70 hstnamevirtual

Argument list too long

If there are many files and your ls, rm or mv commands not working you can use one of these

find /path/to -name 'yourfiles*' | xargs rm
find /path/to -name 'yourfiles*' | xargs -i mv {} anildel/
find /path/to -name 'yourfiles*' -exec rm '{}' \;
find /path/to -name 'yourfiles*' -exec rm '{}' +

Sendmail Troubleshooting

First of all I recommend enabling logging. Edit /etc/syslog.conf and be careful about using tab between entries.
mail.debug /var/log/mail.log

Restart syslog daemon
/etc/init.d/syslog restart

Check /var/log/mail.log.
You can find brief information about sendmail Email flow

commands
..
..
.
date2=`date +%s`
date -d "00:00:00 $(( ${date2} - ${date1} )) seconds" +"%H:%m:%S"

Sed and awk, find pattern and get next lines

Search pattern and print next two lines. You can add more getline and print here for awk and n;p for sed. Also you can do it via +2p

awk  '/pattern/{getline;print;getline;getline;print}' file
sed -n '/pattern/{n;p;n;p;}' file
sed -n '/pattern/,+2p' file

Get between two pattern

awk '/pattern1/,/pattern2/' file
sed -n '/pattern1/,/pattern2/p' file

This is small script do same another way.

pattern=yourpattern
bgn=$(grep -n $pattern scsconfig.log  awk -F: {'print $1'})
ed=`expr $bgn + 3`
cat scsconfig.log  sed -n ''$bgn','$ed'p'

Ext3 journaling

Get your journalling mode
cat /proc/mounts | egrep "ext3"

Journal
(slow, but least risky) Both metadata and file contents are written to the journal before being committed to the main file system. This improves reliability at a performance penalty because all data has to be written twice. Without this setting in /etc/fstab, a file being edited in-place during a power outage or kernel panic risks being corrupted, depending on how the application is writing to the file.

Ordered
(medium speed, medium risk) Ordered is as with writeback, but forces file contents to be written before its associated metadata is marked as committed in the journal. This is the default on many Linux distributions.

Writeback
(fastest, most risky; equivalent to ext2 in some sense) Here metadata is journaled but file contents are not. This is faster, but introduces the hazard of out-of-order writes where, for example, files being appended to during a crash may gain a tail of garbage on the next mount.

Set or clear the indicated default mount options in the filesystem
tune2fs -O has_journal -o journal_data /dev/hdXY
tune2fs -O has_journal -o journal_data_ordered /dev/hdXY
tune2fs -O has_journal -o journal_data_writeback/dev/hdXY

Also you can define when you are mounting
mount -o data=journal /dev/hdXY /mountpoint
mount -o data=ordered /dev/hdXY /mountpoint
mount -o data=writeback /dev/hdXY /mountpoint

Or in fstab file
LABEL=test /mountpoint ext3 data=writeback 0 0

Export Local Group Policy settings to other Pc

If you want to move local policy settings to other Windows OS, move files under %systemroot%\system32\grouppolicy\ to other system.
Also if you delete files under this directory, you system will not have group policy. Do not forget to log off log on.
If you are managing workgroup. You can use this method for distributing policy.

Data Execution Prevention problems

After converting physical machine to VMware virtual machine, I had problems opening display properties. Data execution prevention prevented some features.
Changing settings under system properties --> advanced--> data execution prevention and allowing application did not help.
So I edited boot.ini and disabled DEP via adding /noexecute=AlwaysOff .
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=AlwaysOff

Fedora 6 make music via Rosegarden and CT 670

Rosegarden is free software digital audio workstation. It has MIDI and audio playback.
So I connected my Casio CT 670 keyboard, and played midi files via Rosegarden.
Keyboard has 4 channel so I also use software synth (qynth) for having more channels. But If you want to have good sound via software synth you have to have good sound card (asio drive prefered).

Install Rosegarden
yum install qjackctl fluidsyth fluid-soundfont qsynth rosegarden4

run
qjackctl -> this is for connecting qynth your midi device and rosegarden
qsynth --> software synth, you can find soundfonts from internet
rosegarden

Boot problem Solaris i386

I got below from http://blogs.sun.com/tdh/entry/grub_error_17_cannot_mount and I used this for fixing problem.

"error 17, cannot mount selected partition"

1. Boot into Solaris Safeboot mode. You can get access at the Grub menu, usually the 2nd option. Note: I had to use the DVD install media to do this.
2. Mount the found Solaris partition on /a Safeboot will usually find the slice on the disk with Solaris and ask if you want it to mount on /a. Select Yes.
3. Move /a/dev, /a/devices, and /a/etc/path_to_inst to another name (I just append .orig) and then create new directories, (mkdir) /a/dev and /a/devices, and touch /a/etc/path_to_inst. I did not do this step.
4. Run "devfsadm -r /a" to rebuild the device tree.
5. Edit /a/boot/solaris/bootenv.rc and modify the line with "setprop bootpath '/pci@0,0....' to match the path you'll find mounted for /a (i.e. run a 'df -k' command, and you should see /a mounted from /dev/dsk/c1d0s0 or something, then run 'ls -l /dev/dsk/c1d0s0' or whatever your device listed was, and you should see the actual link point to ../../devices/pci@0,0/...) The path to bootpath you want should be the hard disk which is mounted as /a and you just need to find the expanded /devices/pci@0,0/... path and put that in the bootenv.rc file on the Solaris root filesystem on the hard disk (sans the /devices/ prefix of course). This is a key step.
6. Now run "bootadm update-archive -v -R /a" to rebuild the boot-archive on /a.
7. Make sure to edit /etc/vfstab
8. run a 'touch /a/reconfigure'
9. Run "cd /; sync; sync; sync; umount /a" And I skipped this one.
10. and finally reboot.

Be sure devices are connected now. If you have problem in this step and for the rest of them, I highly recommend check configuration of 3510 .

#luxadm -e port
/devices/pci@0,0/pci10de,5d@e/pci1077,143@0/fp@0,0:devctl          CONNECTED
/devices/pci@0,0/pci10de,5d@e/pci1077,143@0,1/fp@0,0:devctl        NOT CONNECTED
/devices/pci@0,0/pci10de,5d@d/pci1077,143@0/fp@0,0:devctl          CONNECTED
/devices/pci@0,0/pci10de,5d@d/pci1077,143@0,1/fp@0,0:devctl        NOT CONNECTED

And see that disk devices are ok.

#luxadm -e dump_map /devices/pci@0,0/pci10de,5d@e/pci1077,143@0/fp@0,0:devctl

and

Now check that they are connected and configured, if not configure them

#cfgadm -al

and run devfsadm command to build device tree. and see them with format command.

Fedora WPA wpa_supplicant

Operating system ; Fedora Linux 6
Wireless Card ; Dlink D520 atheros based wireless pci card

For enabling wpa install wpa_supplicant*.rpm

edit /etc/wpa_supplicant/wpa_supplicant.conf


ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
#
# home network; allow all valid ciphers
network={
ssid="yourssid"
scan_ssid=1
key_mgmt=WPA-PSK
psk="yourpassword"
}

And add line to /etc/rc.local for starting at boot time run the commands for starting wpa
wpa_supplicant -B -c/etc/wpa_supplicant.conf -iath0 -Dmadwifi &
dhclient ath0

So WPA

Use WPA, if your wireless modem supports.
For cracking WPA, attacker has to do dictionary attack. If you use complex password, it is nearly impossible to hack WPA, if your password is not in the dictionary.
Also for cracking WPA, attacker has to catch handshake data, there are some ways to force handshake . But again the reason above, it is really hard to hack WPA wireless network.

What about 128 bit WEP

For best data collection I use --ivs --channel and --bssid options for airdump.
I collect about 300000 ivs. Collection time for ivs depends traffic for the wireless network.
And again it took about a second to find the key I used.

For more security with WEP use dynamic key provisioning. 128 bit key or more. Then the attacker has to collect more data to hack your network.
Also use MAC filter and disable SSID Broadcast. But do not forget it is possible to change mac address and find your hidden SSID for an attacker.

Risky WEP 64 bit

This is for testing purpose and it is about my home network. I highly recommend not to access networks you do are not allowed to. This could be illegal for some countries.

I have HP Pavilion dv6000 series (dv6699ea)
I use BackTrack distro live cd (http://distrowatch.com/table.php?distribution=backtrack)
I configured my wireless adsl modem 64 bit key.

After booting linux,
dv6699ea has ipw3945 wireless. You have to start wireless for this version:
cd /usr/src/drivers/ipw3945-1.2.0/ && ./load
aircrack support certain wireless cards please check it
http://www.aircrack-ng.org

Dump from wireless interface
bt ~ # airodump-ng eth1 --write test1

After collecting enough
bt ~ # aircrack-ng test1.ivs

It takes about less than a second to find keys for 64 bit.
So never use 64bit WEP wireless adsl  modem.

I also tried
 atheros based Dlink D520 in Fedora 6
and U.S. Robotics USB Adapter USR805422 in Windows XP.  It worked.

Script is not running as cron job

Be sure you set cron job right.
I assume your script is running manually.
You can check it has executed from cron
# tail -f /var/log/cron

Also check root mails to errors.
# less /var/mail/root

Probably you have environment variables problem.
You can check differences between you cron and command environment
# env > /tmp/envmanual
and put a cron job
* * * * * env > /tmp/envcron

Look for differences
# diff /tmp/env*
Put differences that you found in your script and export them.
e.g export TERM=linux

Oracle tablespace Backup/Restore (OS backup)

I tested tablespace recovery.

Be sure your database in archive mode
SQL> archive log list;
SQL> select count(*) from hr.employees;

Begin backup.
SQL> alter tablespace example begin backup;
Check the tablespace in backup state
SQL> select * from v$backup;
Prepare hr account
SQL> alter user hr account unlock;
SQL> alter user hr identified by hr;
# sqlplus hr/hr
Make some changes
SQL> create table employees2 as select * from employees;

Backup your file (This means that if you put your database in backup state you can do filesystem backup for oracle)
# cp example01.dbf example01.dbf.backup
End backup mode
# sqlplus / as sysdba
SQL> alter tablespace example end backup;

Shutdown database, delete table and restore table
SQL> shutdown abort;
# rm example01.dbf
# sqlplus / as sysdba
SQL> startup
ORA-01157: cannot identify/lock data file 5 - see DBWR trace file
ORA-01110: data file 5: '/u01/app/oracle/oradata/orcl/example01.dbf'

You want database to be open while you are restoring tablespace.
SQL> alter database datafile '/path/example01.dbf' offline;
SQL> alter database open;

Restore tablespace and recover it
# mv example01.dbf.backup example01.dbf
SQL> recover tablespace example;
SQL> alter tablespace example online;

Verify recovery
# sqlplus hr/hr
SQL> select count(*) from employees2;

Oracle Offline Database Backup/Restore (OS backup)

I did some tests. Here I backed up oracle and do some changes. Later I restored with copying files. You can just copy or use any backup software.

Backup
RMAN> connect target;
RMAN> shutdown immediate;
copy oracle datafiles to backup directory
#cp -R /oracle_datafiles_dir/* /backup_dir/
remove redolog files
#rm redo*.log /backdir

Break down your database
open database and do some changes
RMAN> startup;
shutdown database and delete datafiles
RMAN> shutdown immediate;
#rm /oracle_datafiles_dir/*.dbf

Restore
Move backup files to original directory
#cp -R /backup_dir/* /oracle_datafiles_dir/
start database
RMAN> startup mount;
RMAN> recover database until cancel;
RMAN> alter database open resetlogs;

You do not have to do last two steps if you backup redo logs and restore it.

Understanding Load Average

Please take a look for details:
http://www.teamquest.com/resources/gunther/display/5/index.htm


Summary

So, what have we learned? Those three innocuous looking numbers in the LA triplet have a surprising amount of depth behind them.

The triplet is intended to provide you with some kind of information about how much work has been done on the system in the recent past (1 minute), the past (5 minutes) and the distant past (15 minutes).

As you will have discovered if you tried the LA Triplets quiz, there are problems:

1. The "load" is not the utilization but the total queue length.
2. They are point samples of three different time series.
3. They are exponentially-damped moving averages.
4. They are in the wrong order to represent trend information.

Schtasks

I set scheduled tasks with schtasks command to create for all servers.
This command create task which runs every 5 minutes.


schtasks /create /s "\\server" /U domain\username /p "password" /SC MINUTE /MO 5 /tn taskname /tr "scriptpath"

ERROR: passing the user credential on local connection.
You have to give server name in this format "\\server"

Vbscript write log file entries to event log

this script reads log files at these server and writes every line to windows event log for the related server.
you can specify search keyword via regex for lines. Please find detailed information here http://msdn2.microsoft.com/en-us/library/ms974570.aspx#scripting05_topic2
change regex details for yourself.
If there is any error when executing script, it sends you an email about the problem.

I use this script Global Array Manager (GAM) log entries for writing them to windows event log. So we can monitor these entries and raise error via MOM.

Python ssh paramiko run command at every server

I have more than 40 linux server and sometimes I need to check something at servers one by one. I got tired and started to use this script.
You have to install paramiko module http://www.lag.net/paramiko/ . You need to have same username for every server. This script asks you a username password and command to execute at servers.

#!/usr/bin/python
#import sys, os, base64, getpass, socket, traceback, termios, tty, select
import paramiko, getpass

serverList = ["ipadress1","ipadress2"]

command=raw_input("Command: ")
userName=raw_input("User: ")
userPass=getpass.getpass("Password: ")

for server in serverList:
        t = paramiko.Transport((server,22))
        try:
                t.connect(username=userName,password=userPass,hostkey=None)
        except:
                print server + ": Bad password or login!"
                t.close()
                break
        else:
                ch = t.open_channel(kind = "session")
                ch.exec_command(command)
                if (ch.recv_ready):
                        print server + ": " + ch.recv(1000)

Monitor your adsl bandwith usage

I use fedora 6, mrtg and snmp tools to monitor adsl router bandwith for all interfaces (wlan,atm,lan)

install packages:
net-snmp
net-snmp-utils
mrtg
You can install yum install packagename. Or download package and rpm -ivh package name.

configure mrtg:
for snmp v1:
cfgmaker --output=/etc/mrtg/mrtg.cfg --global \
"workdir: /var/www/mrtg" -ifref=ip \
--global 'options[_]: growright,bits' public@192.168.2.1
for snmp v2:

cfgmaker --output=/etc/mrtg/192.168.2.1.cfg \
-ifref=ip --global "workdir: /var/www/mrtg" \
--snmp-options=:::::2 public@192.168.2.1



for public@192.168.2.1 use your snmp community and your adsl router ip address.
check your /etc/mrtg/mrtg.cfg and comment out interfaces you want to monitor.

run this command three times to collect data. You will get error for the first two times.
env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

make your html page:
indexmaker --output=/var/www/mrtg/index.html \
/etc/mrtg/mrtg.cfg

put configuration to crontab:
0-59/5 * * * * root env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

httpd configuration:
edit configuration /etc/httpd/conf.d/mrtg.conf and comment deny restrictions if you want to access your http service remotely.
then start service
service httpd start

enable this service
chkconfig httpd on

access your mrtg page http://yourmachineipadressorhostname/mrtg/

ssh auto login

You want to auto login Host B from Host A
Host A Look in your ~/.ssh directory. There should be two files, id_rsa and id_rsa.pub. If not, create them using ssh-keygen -t rsa.
Host B Append local id_rsa.pub to the Host B ~/.ssh/authorized_keys.
The file mode of ~/.ssh/authorized_keys must be 644. You can assure this with chmod 644 ~/.ssh/authorized_keys
You might have to change your /etc/sshd_config and add the following lines:
RSAAuthentication yes
PubkeyAuthentication yes

Hp Openview active passive state

I coded this script because hp openview does not have script to track status of active and passive system together and reflect status of service(I mean two server is working for one aim) in service graph screen.
Put this script both active and passive system. It is going to help tracking status of servers and if active system goes down the script running on passive system change status to critical in service graph screen. If passive system goes down the script on the active system is going to change status to ok in service graph screen why because active system is working, so you are serving you service.
You have to create this file C:\Documents and Settings\Administrator\Desktop\ACTIVE on the active server.

Hp Openview Microsoft Windows file check template

Hp Openview does not have all the scripts for Windows, so I coded this vbscript to help us checking if the file exist and changes related monitoring status. This script has to be run from hp openview services. You have to call script with file name and monitoring name from HP Openview.

Forwarding root mails to your inbox

Forward all root mails to your email address

edit /etc/resolv.conf
put you dns servers which knows your email server.
domain domainname
nameserver x.x.x.x
nameserver x.x.x.x
be sure you can resolve domain.

and create .forward and add your email address into this file.
As you see you do not need to configure sendmail...
Check status from maillog tail -f /var/log/maillog

Password recovery Red Hat, Fedora Linux

Follow the procedure at "bootloader is corrupted Fedora Linux-recue it"
do not do grub-install
after chroot edit /etc/shadow
root:deleteallcharachterhere:13222:0:99999:7:::
root::13222:0:99999:7:::
You password is empty now.
Probably passwd command also will help you to change your password.

Go to a runlevel at boot time with grub

You want to go certain run level in Fedora or Red Hat Linux with GRUB.

on boot at GRUB splash screen
press any key
select boot option that you want boot from
press a to append
press space and write here which run level you want to go (1,2,3,emergency,s)
kernel /vmlinuz-2.6.9-5.ELsmp ro root=LABEL=/ hda=ide-scsi rhgb quiet 1
press enter and booting...

BTW brief information
1 : this is going to process rc.sysinit and rc1.d scripts
s, S, or single : this is going to process only rc.sysinit
emergency : this is going to run sulogin only

System crontab files in Fedora, Red Hat Linux

Fedora and Red Hat cron files somewhat different than other Unix.
If you want to look for all cron job do not forget to look

/etc/cron.hourly
/etc/cron.daily
/etc/cron.weekly
/etc/cron.monthly
/etc/crontab

And crontab -e as you know...

Most used rpm commands

Automatic installation, you are tired of installing packages one by one and finding requirements use this:
rpm –ivh --aid xsane*

Ok this is most useful (after install option :)) command that checks if package files changed
rpm -V packagename

If you want to be sure that you are installing signed packages
gpg --import gpg_key (find gpg_key from Red Hat)
rpm --import gpg_key
rpm --checksig package_file_name (This command checks signature)


rpm -qa (gives all packages installed)
rpm -q packagename -i (gives package information)
rpm -q packagename -l (list files in the package)
rpm -q packagename --requires (show which package required to install this package)
rpm -q packagename -scripts (gives you installation script)
rpm -q packagename -changelog (gives you changelog information about package)

rpm2cpio (Use this for extracting rpm packages)

Controlling services under Red Hat , Fedora Linux

Graphical tools
system-config-services (or redhat-config-services ) requires X interface
ntsysv

Command line tools
service (service smb stop)

List all services and change status
chkconfig --list (gives all services and status)
chkconfig smb off/on (stop starting services after restart)

Set ip adress in Fedora Red Hat

If you are not familiar with commands and configuration files use this command
netconfig
This tool works in terminal, telnet or ssh.

Ok you want to create virtual ip adress or virtual ethernet interface
netconfig -d eth0:0

Pretty simple

Hardware information Fedora Red Hat

use these commands to get hardware information
lspci
lspnp
For detailed information use verbose option (lspci -v )

Also you can get information from /proc
cat /proc/bus/pci/*
cat /proc/isapnp
cat /proc/scsi/*

USB and IEEE 1394 Buses
/sbin/hotplug, (/etc/hotplug)

Information in /proc/bus subdirectories
/sbin/lsusb and /sbin/usbmodules utilities

Process explorer

If task manager in windows is not enough for you use this tool.
You can use this tool to suspend some process, if they are spy ware or etc. before cleaning.

Process Explorer shows you information about which handles and DLLs processes have opened or loaded.
The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.

ghost or copy a partition to another drive- create identical system

I used this procedure copy my Fedora Linux OS.
Boot server in rescue mode

Boot the server from CDROM with rescue mode. At the boot prompt:
linux rescue

Choose mount filesystem when it is asked.

Create folder under root
mkdir /destination

Mount your destination partition under
mount /dev/hdb1 /destination

Copy all of them, because all files are not used by any process you will not have any problem
cp -ar /mnt/sysimage /destination

or copy all disk
dd if=/dev/hda of=/dev/hdb


If you are copying your boot partition you have to install grub for booting system
move hdb to hda (You have to switch master slave jumpers for both of disks)
Boot with rescue mode, mount filesystem (if you have problem, you know partitin location mount /dev/sda1 /mnt/sysimage)
chroot /mnt/sysimage
grub-install

Now you have copy of the system...

bootloader is corrupted Fedora Linux -- Rescue it

Boot the server from CDROM with rescue mode. At the boot prompt:

Install group boot loader.
grub-install /dev/sda

Reboot your server.

SAN driver on Red Hat

There are some trick for installing qla drivers in Red Hat servers:
One of them is using up to date gcc
The other is you need up to date cciss driver, because if you compile qla drivers with old cciss driver, servers try to boot from storage through hba.

BTW there is another important situation, your device number could change in the future, if you mount with device names it could cause problems after mounting.
So I strictly recommend to label your disks

e2label /dev/sda1 DATA01
fstab --> LABEL= DATA01 data01 ext3 defaults 1 2



OS : Red Hat Linux Advanced Server release 2.1AS (Pensacola)
kernel : 2.4.9-e.35smp
Hardware : HP DL380
HBA : qla2300
Storage : HITACHI DF600F or EMC SYMMETRIX 5771

Installed cciss driver cause trouble, so backup them
cd /lib/modules/2.4.9-e.35smp/kernel/drivers/addon/cciss/
cp cciss.o cciss.o.old
cd /lib/modules/2.4.9-e.35/kernel/drivers/addon/cciss
cp cciss.o cciss.o.old

Install new version
rpm -ivh cpq_cciss-2.4.54-14.rhel21.i686.rpm
reboot server, see if it is booting

Use up to date gcc
mv /usr/bin/gcc /usr/bin/gcc.296
ln -s /usr/bin/gcc3 /usr/bin/gcc

Install HBA driver
rpm -ivh hp_qla2x00src-7.05.00p8-19.linux.rpm

Install fibeutils you are going to use this
rpm -ivh fibreutils-2.0-4b.linux.i386.rpm
Reboot server

HP Raid control in Linux

Think that you are using HP DL series (DL380) hardware and running linux, you want to check raid status then you need:

• Install hpacucli from HP.
• Run this script
  

#!/bin/sh
SLOTLIST=$(hpacucli ctrl all show | \
grep Slot | sed -e 's/^.*Slot //g' -e 's/ .*$//g')

for i in $SLOTLIST
do
echo
hpacucli ctrl slot=$i show status | grep -v "^$"
echo
hpacucli ctrl slot=$i ld all show status | grep -v "^$"
hpacucli ctrl slot=$i pd all show status | grep -v "^$"
done
echo

• Output:

Fujitsu Siemens servers - Server View Agents -

We try to get events from hardware for Fujitsu Siemens servers running Windows OS.
Here is the way how can we collect events for pdu,disk etc.
You have to install GAM for disk messages.

Logging Server View Events to Windows Event Log
Open ServerViewAgents --> Agent Configuration-->Trap Forwarding
Select all for Report to system event log
Choose apply
Then restart serverview agents tool and Click restart.

GAM Installation
Find installation file from lsilogic web site.
Run installation file

There is trick when you want to change settings
If there isnt a user named gamroot in the domain, create user and give a password.
It will be used when you need to change settings. Or you can create user locally.

Osiris

I implemented Osiris version 4.2.3 in the company. I compile it on Fedora 7 and running on Vmware ESX.

web site
http://osiris.shmoo.com/

You can find comparison of host integrity tools here
http://www.securityfocus.com/infocus/1771

Osiris:
Osiris is a Host Integrity Monitoring System that periodically monitors one or more hosts for change. It maintains detailed logs of changes to the file system, user and group lists, resident kernel modules, and more. Osiris can be configured to email these logs to the administrator. Hosts are periodically scanned and, if desired, the records can be maintained for forensic purposes. Osiris keeps an administrator apprised of possible attacks and/or nasty little trojans. The purpose here is to isolate changes that indicate a break-in or a compromised system. Osiris makes use of OpenSSL for encryption and authentication in all components.

Filtering is a bit complicated.
\[mq.*\]\[.*\]\[/opt/oracle/product/RDBMS10g/.*_dwh.*\]\[(mtime|ctime|checksum|inode)\]
.* is like * in unix.

Also you can configure filtering in configuration of hosts:

exclude file (^/opt/oracle/product/RDBMS10g/dbs/spfiledwh.ora$)
exclude file (^/opt/oracle/product/RDBMS10g/dbs/lkDWH$)
exclude file (^/opt/oracle/product/RDBMS10g/dbs/orapwdwh$)
exclude file ("product/RDBMS10g/dbs/snapcf_dwh.f")
exclude file ("product/RDBMS10g/dbs/snapcf_dwh.f")
exclude file (^/opt/oracle/product/RDBMS10g/dbs/hc_dwh.dat$)

Enabling remote logging for Syslog

If you want to enable remote logging in Red Hat edit /etc/sysconfig/syslog file.
change the line like below

BTW editing this file /etc/init.d/syslog does not help.

Webmin

I use this product for a long time. It helped me to manage my Linux machine when I didn't know not much about Linux.
Also I used it with Solaris machines at the work at 2003. I distribute some sendmail rights to people.
Now I am using webmin for accessing my computer from work.

Check process

I use this simple python script to check bittorrent process and if it is not running it starts to vnc.

import os
def check_proc( *args ):
        process = os.popen("ps -ef | grep bitt").read().splitlines()
        if len(process) > 2:
                print "process running"
        else:
                print "process not running"
                os.system('su - user -c "export DISPLAY=127.0.0.1:2.0;bittorrent&"')"

mount -o loop F-7-i386-DVD.iso /mnt/disk3part3/xen/fedora
Put below to /etc/exports
/mnt/disk3part3/xen/fedora
start nfs service
service nfs start

encrypted partition in linux

Put hese into rc.local file for loading crypto modules.
modprobe cryptoloop
modprobe aes

if you need many loop device add below to modprobe.conf file.
options loop max_loop=32

Prepare encrypted file about 40Gb
dd if=/dev/zero of=/mnt/disk3part4/xfile01 bs=100M count=400
losetup -e aes /dev/loop1 /mnt/disk3part4/xfile01
mkfs -t ext2 /dev/loop1

Mounting encrypted file
losetup -e aes /dev/loop11 /mnt/disk3part4/xfile01
mount -o loop /dev/loop11 /home/username/torrent01
