I always want to know when root logs in to my server. It is a security measure I cope with in my mailbox deleting mails after I logged in as well.  Here is a little help for you all to receive mail when root logs in via ssh.

In case your Python is giving your problems on EnsimX server and you get  “500 Internal error” errors then thig guide can help you. I found it on ensim forums and it helped me so I saved it for future reference. Read the rest of this entry »

After upgrading to EnsimX 10.3.0 or in clean  EnsimX 10.3.0 installation there is issue having high MailScanner load.

Take a look at this knowledge base article  for a solution.

 You just download files that belong to your OS and then run

rpm -Uvh *.rpm

sh upgrade.sh

Despite all efforts EnsimX Pro was still using old www.snakeoil.com certificate instead the one I generated/bought for use for apache ssl. I tried various ways how to fix this but epld service was refusing to start or the snakeoil certificate returned back after a few days.

Here is solution that fixes it :

I always wanted to see mail stats on my server, who receives and sends the most mails, what are the busiest hours, etc.. to better track mail problems, catch spammers and to satisfy my admin’s ego . I found this little script that goes through senmail’s log and produces output. In my case I will send the output to root via email.

Here are the features that I receive from this little script:

SendmailStats reports:

• Time/date of log beginning and end
• Total bytes transferred and total MB transferred
• Total bytes in and total MB in (locally delivered)
• Number of messages sent out
• Number of messages coming in
• Messages per hour graph
• Top 20 remote sending hosts
• Total number of sending hosts and number of their attempted messages
• Top 20 destination hosts
• Total number of destination hosts and number of messages sent to them
• Top 20 local deliveries
• Total number of local accounts that received mail
• Total number of messages delivered locally
• Top 20 senders
• Total number of senders and total number of messages sent Read the rest of this entry »

I have been noticing a very annoying delay when trying to log in via FTP on servers where I use proftpd. Everything works, but when I try to connect, 5 – 10 seconds pass by before I’m prompted for my login credentials. After long hour of searching on the internet I found a solution.

 All you need to do is edit the config file which should be /etc/proftpd/proftpd.conf  and place this line within <global> section:

 IdentLookups Off

 That should remove the delay and your ftp connection will be initialized very quickly.

During the time Ensim evolved it used to call its servrice either ‘webppliance’ or ‘epld’ (newer). So the command you need to run as root via shell to restart Ensim is:

If you use version older than 10.x.x

 # service webppliance restart  

If you use version EnsimX for Linux 10.x and higher

# service epld restart

I hope this helps

This tutorial section deals with mysqldump which is a tool to import and export MySQL databases.

It can be used to back up a database or to move database information from one server to another.

I always hated to go to Ensim to find out the current version of it.  Finally I  somewhere found a command that writes this info in shell.

He it is: 

cat /usr/lib/opcenter/VERSION

Many times it happened to me – I forgot Ensim’s admin password for web interface or DC has just set some password and they “forgot” to inform me. I usually struggled via ssh how to change it. Not anymore..

 When you need to reset Ensim password do it by this:

/usr/sbin/passwd_appl_admin <username>

It will prompt for the password only once.
