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.

Dim machine
Set fs=CreateObject("Scripting.FileSystemObject")
machine = "server1" 'write other 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.

strArgument1 = Wscript.Arguments(0)        'file name
strArgument2 = Wscript.Arguments(1)        'monitor name 
Set objFs=CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("WScript.Shell")
StrOpcmon = "c:\usr\OV\bin\OpC\opcmon" 

If objFs.FileExists (strArgument1)then 
 strCommand = StrOpcmon & " " & strArgument2 & "=1"
 intRC = objShell.Run (strCommand,1 ,TRUE)
 Else 
 strCommand = StrOpcmon & " " & strArgument2 & "=0"
 intRC = objShell.Run (strCommand,1 ,TRUE)
End If

Sync directories Fedora , Red Hat Linux encrypted

I use this script to sync my scripts to other servers. -e ssh option make communication encrypted.

rsync.conf includes folders like this source, dest directories.
/usr/local/test/;/usr/local/test/

rsynchosts.conf put hostnames (a host for every line)

REMOTEUSER=username
CONFFILE=/usr/local/etc/rsync.conf
HOSTFILE=/usr/local/etc/rsynchosts.conf


cat $HOSTFILE | grep -v "#" | while read HOSTFILE
do
        REMOTEHOST=`echo $HOSTFILE |awk -F";" '{ print $1 }'`


                cat $CONFFILE | grep -v "#" | while read CONF
                do
                LOCALDIR=`echo $CONF |awk -F";" '{ print $1 }'`
                REMOTEDIR=`echo $CONF |awk -F";" '{ print $2 }'`

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)

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

PCMCIA Bus
/sbin/cardmgr, (/etc/pcmcia/)

Information in /proc/bus/pccard
/sbin/cardctl utility

John the Ripper identify weak passwords

You can check your users if they are using weak passwords,

get you /etc/shadow file

make word list if you predict common word or find here http://www.word-list.com/

following command gives you user names and you can use this file as a dictionary(this is going to help who used username and password same).

cat /etc/passwd | awk -F : '{print $1}' > word.lst

merge dictionary files.

use John the Ripper,
john --wordlist=word.lst shadow

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:

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

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:

Smart Array 6i in Slot 0
Controller Status: OK
Cache Status: OK

logicaldrive 1 (203 GB, 5): Ok
physicaldrive 2:0 (port 2:id 0, 72.8 GB): OK
physicaldrive 2:1 (port 2:id 1, 72.8 GB): OK
physicaldrive 2:2 (port 2:id 2, 72.8 GB): OK
physicaldrive 2:3 (port 2:id 3, 72.8 GB): OK

Osiris [info] outgoing: error message.

I was getting this annoying error from Red Hat 7 servers.

[info] outgoing: error message.

So I moved to service into quite mode with editing /etc/init.d/osirisd
adding -q option.
line: daemon $osirisd -q -r $osirisd_root $OPTIONS

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
SYSLOGD_OPTIONS="-m 0 -r"

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

Ipod torrent

Good sites for ipod content. Use them with your own risk.

Avi to mp4 with subtitle

Very strange that there is only one program could convert avi and subtitle files to Ipod compatible mp4 file.

xvid4psp runs on windows.

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.

Ssh on port 80

I use this command to open another ssh daemon listening on port 80. It helps to pass away proxy servers.

/usr/sbin/sshd -p 80

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&"')"

Xen in Fedora 6 part 1

I followed http://fedoraproject.org/wiki/FedoraXenQuickstartFC6 this procedure.
I used nfs for install location, dont forget to give real ip adress of your nfs (never write 127.0.0.1)

Simply building nfs server :
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

VNC

Configuration of VNC in Fedora 6
run vncconfig

edit /etc/sysconfig/vncservers
VNCSERVERS="2:username"
VNCSERVERARGS[2]="-geometry 1024x768"

add /home/username/.vnc/xstartup
gnome-session&

start vnc server sevice
service vncserver start
