Please direct all admin related messages to admin@dbai.tuwien.ac.at instead of individual users.
Bug reports should be as detailed as possible and include the time the problem occurred, error messages, and full instructions on how to reproduce the problem (machines involved, particular input files and/or options,...), if appropriate.
Requests regarding e-mail should contain the full headers of the
message(s) in question. Requests regarding printing problems should include the output of "lpq -P[Drucker] -llll".
First of all have a look at our mail configuration.
If you want to forward e-mail to another e-mail address you have to put a ".forward" file into your home-directory. For example, if user chris has a .forward file containing the following lines:
chris@freemail.com
\chris
one copy of mail will be forwarded to chris@freemail and another copy will be retained as mail for local user chris.
For additional information see "man forward".
All of our printers are networked Postscript devices. By default,
most user accounts do not have print permissions, i.e., they do not
belong to groups laser (required for lw1, lw2, lw3, lw4, lw5,
lw6 and lw7) resp. colorlaser (required for cl1)
The usually used UNIX tools for printing are lpr resp.
a2ps for printing, lpq for status information and
lprm for removing queued print jobs. If you want to print single
sided on a double side printer use "lpr -o sides=one-sided ...".
Warning: Do not send .dvi files directly to the printers, it will produce tons of pages with garbage.
If you have to print from a Windows machine outside our department network (e.g. you are connected per WLAN):For special printing demands (e.g. A3 format) there is a copy center two houses
away from us. Ask the
secretaries for the copy
card.
Windows
Usually our file server (where your home directory resides) should appear in the "network neighbourhood" of the internet explorer, where you can access your home directory and use the printers. If it doesn't, please use the following workaround:
Due to security constraints, we solely rely on SSH (protocol version 2.x) or one time passwords for remote login and file transfer; normal telnet, ftp and (unencrypted) imap are generally disabled.
If you want to login from an unsecure system, please use our one time password system (IMAP isn't yet available that way).
Generally for remote connections you may use sg1.dbai (SSH),
sg2.dbai (SSH) and vexpert.dbai (IMAPS). Login to
a group account doesn't work this way, please login as
normal user instead and change to the group account with su -
<groupaccount>
afterwards.
(Any decent Unix installation these days already has SSH installed. For Windows we recommend PuTTY.
Please log out, when you finish your working day (both remote and local). If
you however have to run a program over several days, please send an appropriate mail to
admin@dbai.tuwien.ac.at.
Backup
The home directories, the mailbox directory, the /web and the /proj directory are backed up on Tue, Wed, Thu, Fri and Sat starting at 2:35am. Also all user datas from mysql, wiki and svn servers.
Every month a set of these backups is stored for two years. Among these, every fourth set will be stored for another two years. This means that home directories and web data are stored for four years (at least in an interval of four months).
