nasty questions

1. Q: Who is going to use it? A: Everybody doing software development! Everybody wanting the latest WHATEVER.
2. Q: Why should I do? A: source history, teaming up, source branches, ...
3. Q: Besides its cool features. Why should I do? A1: To set you up in software heaven. A2: new CAAD policy (cause ludger says)
4. Q: Ok. Ok. How should I use it A: I'll put links to serveral clients below. And read the structure chapter.
5. Q: Is it easy to use? A1: Depends on you client. A2: CVS is a one way data sink. You can mess it up. And it is hard to recover.
6. Q: It reminds me on something. What is it? A: TWiki is using CVS for its history.

IP and Host adress management at CAAD

Management of IP Adresse and DNS names is provided by ISG D-Arch. Contact hostmaster@arch.ethz.ch for changes and instructions.

The following information is obsolete, IP adresses are now maintained by ISG D-Arch, contact Thomas Gemperli (hostmaster@arch.ethz.ch) for instructions.

Dynamic IP List at http://fett.ethz.ch/spindler/bin/hosts.pl.

To update a dynamic ip address do the following:

1. at fett use psql to change the entries in the tables mac and host
2. run update-dhcpd.sh as root@fett to write new dhcpd.conf and automatically restart dhcpd
3. check http://fett.ethz.ch/spindler/bin/hosts.pl if the new entry is there
4. monitor /var/log/daemon.log at fett for dhcp requests from the new client

Using postfix

Checking mta in use on Red Hat and Debian

• alternatives --display mta

Changing to postfix/sendmail

• use alternatives --config mta to set mta
• service sendmail/postfix stop
• service postfix/sendmail start

Using postfix

• working directory is /etc/postfix/
• aliases : Change root: postfix to root: VALID EMAIL_ in /etc/aliases!!!
• canonical: Add entry for local root: root root@HOSTNAME.ethz.ch
• main.cf:
  • Set myhostname = HOSTNAME.ethz.ch
  • Set mydomain = hbt.arch.ethz.ch
  • Set myorigin = $mydomain
  • Add canonical_maps = hash:/etc/postfix/canonical
• Call newaliases
• Call postmap canonical
• Monitor /var/log/maillog
• Send test mails from root to local user, from local user to root

The entry in canonical is needed so mail does not get sent to root@hbt.arch.ethz.ch. The entry in aliases is recommended by postfix setup. Settings myhostname is most likely unnecessary but there for completeness. mydomain is used for rewriting of outgoing mails. With standard settings of postifx only mail from 127.0.0.1 will be accepted, none from available non-local interfaces. Drawback of this configuration is, that no local mail is stored and if a mail is locally sent to an account without canonical entry it will end up at user@hbt.arch.ethz.ch.

Using sendmail

Not supported yet.

SSH Access for CAAD server

To restrict the amount of log messages generated by brute force ssh access hacking all CAAD servers should be protect by the following SSH iptables rule.

export EXCEPTIONS="217.162.112.0/23 129.132.0.0/16 131.246.0.0/16"
for sshrule in $(iptables -L INPUT --line-numbers | grep SSH | cut -f1 -d" " | sort -rn)

Der Server läuft auf taler.ethz.ch. Die Videos finden sich unter smb://taler.ethz.ch/videos User ist red oder yellow, mit den entsprechenden Passwörtern

Das Streaming wird automatisch gestartet. Der user 'vlc' wird automatisch angemeldet und die Datei /home/vlc/bin/stream.sh aus /home/vlc/.xinitrc aufgerufen. Der Streaming Server ist per http über http://taler.ethz.ch:4444 erreichbar. Dort ist die Playlist einsehbar. Das Streamingverzeichnis von dem alle Dateien geholt werden ist /srv/media/streams/streamed/ und kann über das obige Samba Share angesprochen werden.

Achtung, taler wird nicht gesichert, d.h. die Videos sollten zu Sicherungszwecken auf einem weiteren Server liegen!

TWiki.Admin Web Preferences

The following settings are web preferences of the TWiki.Admin web. These preferences overwrite the site-level preferences in TWikiPreferences, and can be overwritten by user preferences (your personal topic, i.e. TWikiGuest in the TWiki.Main web)

Preferences:

• CAAD Skin
  • Set SKIN = caadI
• List of topics of the TWiki.Admin web:
  • Set WEBTOPICLIST = Changes | Index | Search | Go

• Web specific background color: (Pick a lighter one of the StandardColors)
  • Set WEBBGCOLOR = #D0D0D0

• List this web in the SiteMap:
  • If yes, set SITEMAPLIST to on, do not set NOSEARCHALL, and add the "what" and "use to..." description for the site map. Make sure to list only links that include the name of the web, e.g. Admin.Topic links.
  • Set SITEMAPLIST = on
  • Set SITEMAPWHAT = Administrative Stuff
  • Set SITEMAPUSETO = document servers and services

• Exclude web from a web="all" search: (Set to on for hidden webs)
  • Set NOSEARCHALL =

• Default template for new topics and form(s) for this web:
  • WebTopicEditTemplate^?: Default template for new topics in this web. (Site-level is used if topic does not exist)
  • TWiki.WebTopicEditTemplate: Site-level default template
  • TWikiForms: How to enable form(s)
  • Set WEBFORMS =

• Users or groups who are not / are allowed to view / change / rename topics in the Admin web: (See TWikiAccessControl)
  • Set DENYWEBVIEW =
  • Set ALLOWWEBVIEW =
  • Set DENYWEBCHANGE =
  • Set ALLOWWEBCHANGE =
  • Set DENYWEBRENAME =
  • Set ALLOWWEBRENAME =

• Users or groups allowed to change or rename this WebPreferences topic: (I.e. TWikiAdminGroup)
  • Set ALLOWTOPICCHANGE =
  • Set ALLOWTOPICRENAME =

• Web preferences that are not allowed to be overridden by user preferences:
  • Set FINALPREFERENCES = WEBTOPICLIST, DENYWEBVIEW, ALLOWWEBVIEW, DENYWEBCHANGE, ALLOWWEBCHANGE, DENYWEBRENAME, ALLOWWEBRENAME

Notes:

• A preference is defined as:
  6 spaces * Set NAME = value
  Example:
  • Set WEBBGCOLOR = #FFFFC0
• Preferences are used as TWikiVariables by enclosing the name in percent signs. Example:
  • When you write variable %WEBBGCOLOR% , it gets expanded to #D0D0D0 .
• The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set WEBCOPYRIGHT before WIKIWEBMASTER since %WEBCOPYRIGHT% uses the %WIKIWEBMASTER% variable.
• You can introduce new preferences variables and use them in your topics and templates. There is no need to change the TWiki engine (Perl scripts).

Related Topics:

• TWikiPreferences has site-level preferences.
• TWikiUsers has a list of user topics. User topics can have optional user preferences.
• TWikiVariables has a list of common %VARIABLES%.
• TWikiAccessControl explains how to restrict access by users or groups.
