This article shows how to run a file-, print-, HTTP proxy- DHCP-, and time server for small and medium enterprises (SME) on one single Debian Sarge system. It is very easy to set up, and management is done with an easy-to-use web interface called eBox so once the system is set up, you can forget about the command line.
…not that I would “forget about the commandline” but this could actually come in handy sometimes.
I completely restructured the comments template in this blog.
The main difference visible is that Trackbacks/Pingbacks are now seperated from the rest of the comments.
I derived most of the ideas from Christian Montoya’s comments template he posted on his site today. Thank you 🙂
I hope I got everything covered in the new template, but still, if there are any problems just tell me 😉
While searching for an easy way to do server side Spam filtering, so I don’t have to bear with all those spams when looking at my Inbox with Webmail, I found IMAP Spam begone. It’s a python script that scans your Inbox for new messages and hands them to Spamassasin to check their spam status and copies them to a pre-defined folder in your Maildir if it is found to be a spam message. Client side spam filtering is done with Apple Mail on my iBook which works very good for me. So there is a second layer of filtering in place in case something still gets through.
Although isbg.py is rather old and hasn’t been updatet in about three years it works very conveniently and tags nearly all of my Spams, moves them to my Junk folder and deletes them from my Inbox. The script is called from a cronjob and run every 10 minutes so there is a slight chance that I still find Spams in my Webmail before isbg.py is able to run and delete them.
The reason I settled for this “external” integration of Spamassasin via isbg.py is that I didn’t want to mess around with the transport rules of my MTA because of the chance to do something not all users are happy with. With IMAP Spam begone I have an individual solution that works for me without altering the way all the other people experience the mail service.
Below you’ll find the command line options I have running, for further explanations please refer to the projects homepage.
isbg.py --spaminbox INBOX.Junk --spamc --delete --nostats --expunge
Update: Since the ISBG site seems to be down currently, I’ll provide a download link for the script here.
Today I finally searched and found a solution for a problem that’s been bugging me for ages now. You all know this nice little message that tells you if you’ve got new mail, when you log into a UNIX box. It is really handy and works out of the box on most systems if you have a “normal” mail server installed.
Well this machine has a more advanced set up, hosting several email domains, a MySQL database backend for user information and on top it uses the “Maildir” format and not the standard “mbox” of most other UNIX systems. All those facts add up to the status quo, which means that the nice little login message returns “no new mail” whenever you log in.
Well, today I found out what to do to work around this. Actually there are only three files that need a little modification:
/etc/login.defs – comment out the MAIL_DIR setting and set the QMAIL_DIR setting to the appropriate. I chose “.Maildir”, why will be explained shortly.
QMAIL_DIR .Maildir/
#MAIL_DIR /var/mail
/etc/pam.d/login – add your Maildir location to the pam_mail.so module
session optional pam_mail.so standard noenv dir=~/.Maildir
/etc/pam.d/ssh – to be able to see this via SSH as well do the same as in /etc/pam.d/login but be carefull not to set the “noenv” setting
session optional pam_mail.so standard dir=~/.Maildir # [1]
So what this basically does is, setting the whole system to “Maildir” rather than to the “mbox” standard and then it tells the operating system where to look for new mails. The way I set this up here is a directory called “.Maildir” in the users home folder. In my case this is no real directory but a symlink to the destination of my new mails in the filesystem.
ln -s /var/opt/vmail/no-panic.at/flo/Maildir /home/flo/.Maildir
That way, every user that has shell access and wants to be greeted with the mail message, just has to set up a symlink to his Maildir in /var/opt/vmail and that’s it 🙂
…so all of you who have accounts here: read this! and don’t ask any more questions – it’s all explained above 😉
I reactivated a (very) old site that I did in my first year at uni. It basically gives you the chance to send in funny quotes from colleagues and lecturers for everybody else to view it. (It’s even got RSS 🙂 )
I know it’s mainly the concept of bash.org copied. But I wrote it all from scratch (in about 5min.) so it’s no exact copy 😉
Unfortunately it’s in german, so unless Google Translate improves or you learn reading my mother tounge you’re out of the game.
