Friday, August 5th, 2011 One of the servers running Cpanel has been suspended today and the Data Center decided to completely bring down our server and gave us access to it only through rescue mode running linux livecd.
Thus I had no way to access the Cpanel web interface to suspend the “hacker” who by the way was running a number of instances of this old Romanian script kiddies brute force ssh scanner called sshscan .
Thanksfully Cpanel is equipped with a number of handy scripts for emergency situations in /scripts directory. These shell management scripts are awesome for situations like this one, where no web access is not avaiable.
To suspend the abuser / (abusive user ) I had to issue the command:
root@rescue [/]# /scripts/suspendacct abuse_user
Changing Shell to /bin/false...chsh: Unknown user context is not authorized to change the shell of abuse_user
Done
Locking Password...Locking password for user abuse_user.
passwd: Success
Done
Suspending mysql users
warn [suspendmysqlusers] abuse_user has no databases.
Notification => reports@santrex.net via EMAIL [level => 3]
Account previously suspended (password was locked).
/bin/df: `/proc/sys/fs/binfmt_misc': No such file or directory
Using Universal Quota Support (quota=0)
Suspended document root /home/abuse_user/public_html
Suspended document root /home/abuse_user/public_html/updateverificationonline.com
Using Universal Quota Support (quota=0)
Updating ftp passwords for abuse_user
Ftp password files updated.
Ftp vhost passwords synced
abuse_user's account has been suspended
That’s all now the user is suspended, so hopefully the DC will bring the server online in few minutes.

Sunday, January 22nd, 2012 Accidently I've removed the Gnome Volume Control while trying to remove an applet nearby from the GNOME main menu panel. Unfortunately in GNOME 2, I couldn't find a way to to return back (restore) Gnome Volume Control to the main panel. After a bit of pondering, I've managed to find a way.
Here is how I managed to restore it back:
1. Navigate to:
System > Preference > Startup Applications
2. Click on Add, then add and type the following:
Name: Volume control
Command: gnome-volume-control-applet
Comment: Launch volume control applet
Adding the gnome-volume-control-applet will launch it every time a new gnome session (with the same user) is initiated. On next gnome login you will see the icon to appear again in the notification area. Cheers 😉

Wednesday, August 24th, 2011 I’ve been playing with configuring a new nagios running on a Linux host which’s aim is to monitor few Windows servers.
The Linux host’s exim is configured to act as relay host to another SMTP server, so all email ending up in the Linux localhost on port 25 is forwarded to the remote SMTP.
The remote smtp only allows the Linux to send email only in case if a real existing username@theserverhostname.com is passed it, otherwise it rejects mail and does not sent properly the email.
As the newly configured Nagios installatio is supposed to do e-mail notification, I was looking for a way to change the default user with which Nagios sends mails, which is inherited directly after the username with which /usr/sbin/nagios3 and /usr/sbin/nrpe are running (on Debian this is nagios@theserverhostname.com).
Thanksfully, there is a work around, I’ve red some forum threads explaning that the username with whch nagios sends mail can be easily changed from /etc/nagios3/commands.cfg by passing the -a “From: custom_user@myserverhostname.com” to all occurance of /usr/bin/mail -s , its preferrable that the -a custom_user@myserverhostname.com is inserted before the -s “” subject option. Hence the occurance of mail command should be changed from:
| /usr/bin/mail -s "** $NOTIFICATIONTYPE$
To:
| /usr/bin/mail -a "From: custom_user@theserverhostname.com" -s "** $NOTIFICATIONTYPE$
Now to read it’s new configurations nagios requirs restart:
debian:~# /etc/init.d/nagios3 restart
...
Now in case of failed services or Hosts Down nagios will send it’s mail from the custom user custom_user@theserverhostname.com and nagios can can send mail properly via the remote relay SMTP host 😉

Thursday, May 5th, 2011 Though I really hate facebook, I was asked today by a friend who is not really into computers to disable, mail notification for him.
The mail notification, annoying feature is one of the stupidest idea someone ever had, as very active facebook users had their inbox totally spammed like with messages from facebook …
Anyways, here is how I removed the facebook email notification
1. Login to facebook
2. Go to Account Settings and click on notifications and then uncheck the option, e.g.:
Account Settigns -> Profile Settings -> Messages
There are a number of messages that facebook by default sents, so in order to remove the mail notification messages I scrolled down and unchecked all related to facebook email notification.

Wednesday, April 27th, 2011 I just completed a fresh Ubuntu 10.10 Maverick-Merkaat install.
Following the installation I used a small script to install a bunch of packages I used on the same notebook before the Ubuntu re-installation.
Now after the number of packages are installed on the newly installed Ubuntu, everytime I login with any GNOME user account I get mail notification settings window to automatically start-up
Closing on every gnome login session the mail settings is not a pleasent experience, therefore I took a bit of seconds to find out what launches the New Mail pop-up window
Here is how the annoying window looks like everytime I login on my ubuntu:
Some of the text on the above screenshot is in Bulgarian as the default configured locale for this Ubuntu install is set to Bulgarian but I hope this doesn’t matter as other people who have the same popup can still recognize the window.
Now to find out the process which spawned the mail notification popup I issued:
root@ubuntu:~# ps ax |grep -i mail 2651 pts/1 Sl+ 0:01 mail-notification --sm-disable
Further on I checked what is the original location of mail notification command :
root@ubuntu:~# which mail-notification
/usr/bin/mail-notification
To be absolutely sure mail-notification does spawn the mail settings window I used pkill -9 mail-notification
As the window suddenly died now I was absolutely sure that mail-notification is spawning the unwanted pop-up window which appeared right after me logging in.
I used dpkg -S to check which package does the mail-notification program belong to as I thought that the solution to get rid of this annoying popup will come to removing the whole package, here is what I did:
root@ubuntu:~# dpkg -S /usr/bin/mail-notification
mail-notification: /usr/bin/mail-notification
root@ubuntu:~#
Now knowing the package I simply wiped it off:
root@ubuntu:~# apt-get remove --yes mail-notification
...
root@ubuntu:~# dpkg --purge mail-notification
...
After that I guarantee you you won’t see the irritating new mail settings pop-up window again.
Farewell mail-notification annoyance, hope to never see you again!!! 🙂
