### Debian late_command
2016-07-11 16:44:26 +02:00
#### Description
Some useful configurations after a Debian installation:
* Smarter rsyslog (more directories and less files in **/var/log**).
2016-07-11 16:50:29 +02:00
* Shorter configuration file and use more files from /etc/rsyslog.d/
* Move log files to directory:
* _kern_ logs from /var/log/kern.log to __/var/log/kernel/kernel.log__
* _user_ logs from /var/log/user.log to __/var/log/security/user.log__
* _mail_ logs from /var/log/mail.… to __/var/log/mail/mail.…__
* _daemon_ logs from /var/log/daemon.log to __/var/log/syslog/daemon.log__
* _auth_ logs from /var/log/auth.log to __/var/log/security/auth.log__
2016-07-20 12:02:56 +02:00
* _lpr_ logs from/var/log/lpr.log to __/var/log/lpr/lpr.log__
2016-07-11 16:50:29 +02:00
* _cron_ logs from /var/log/cron.log to __/var/log/cron/cron.log__
* _localX_ logs from /var/log/localX.log to __/var/log/syslog/localX.log__
* _syslog_ logs from /var/log/syslog.log to __/var/log/syslog/syslog.log__
* _authpriv_ logs from … to __/var/log/security/authpriv.log__
2016-07-11 16:44:26 +02:00
* Smarter logrotate (add timestamp, move some old log files to the same directory,…).
* Remove some useless packages.
2016-07-20 12:02:56 +02:00
* Permit root SSH login with password (no standard user…).

#### How-to use it
* First, make an archive of the script and directories:
```
2016-07-25 10:52:52 +02:00
cd scripts/ ;
tar czvf latecommand.tar.gz latecommand/
2016-07-11 16:44:26 +02:00
```
* Then, it can be use at the end of a Debian preseed file:
```
d-i preseed/late_command string in-target chsh -s /bin/zsh ; \
2016-07-25 10:52:52 +02:00
in-target /usr/bin/tftp ${IP.SRV.TFTP} -c get ${PATH/TO/TFTPD/ROOT}/scripts/latecommand.tar.gz /tmp/latecommand.tar.gz ; \
in-target tar xzf /tmp/latecommand.tar.gz -C /tmp/ ; \
2016-07-11 16:44:26 +02:00
in-target /bin/sh /tmp/latecommand/post.sh
```
