Package: debian-edu-config
Severity: important
Version: 2.12.17
Control: found -1 2.11.56+deb11u3
Hi all,
another debug session with a customer revealed a problem in the
update-hostname-from-ip script that gets called via ifup as post-up
hook script. The script fails with non-zero exitcode at various
places, esp. near the very end of the script: if no hostname could be
found, this is interpreted as failure and the script exits with exit
code 1.
If the site admin has not added a system entry for a given Debian Edu
client host in GOsa², the host will retrieve an IP address, but then
fail in update-hostname-from-ip.
From ifupdown's perspective this is an overall ifup failure and ifup
will kill the related dhclient process of the device that we tried to
ifup... The IPv4 lease will then expire after 30min and will not get
renewed.
There are two solutions at hand for this:
(1) /etc/network/interfaces
```
ifup eth0 inet dhcp
post-up /usr/sbin/update-hostname-from-ip || true
post-up /usr/share/debian-edu-config/tools/update-proxy-from-wpad
```
Note the "|| true" at the end of the first post-up line.
Advantage: update-hostname-from-ip can continue to fail, if the
hostname update was unsuccessful. This would be an honest behaviour.
Disadvantage: we need to tweak this with cfengine3 and all hosts will
require a cf-agent run after having upgraded to a fixed d-e-c version.
This is definitely suboptimal for a Debian Edu bullseye point release
d-e-c pkg upgrade.
(2) in /usr/sbin/update-hostname-from-ip
We could also adjust exit codes of /usr/sbin/update-hostname-from-ip
in a way, so that it always exits with exitcode 0. This will make
ifupdown happy and not config change in /etc/network/interfaces is
required.
(3) mixed approach...
We could use approach (1) for the Debian Edu 12 development branch and
use approach (2) for the Debian Edu bullseye update branch...
Comments, opinions?
Mike

Source: debian-edu-config
Architecture: source
Version: 2.12.18
Distribution: unstable
Urgency: medium
Maintainer: Debian Edu Developers <debian-edu@lists.debian.org>
Changed-By: Mike Gabriel <sunwea...@debian.org>
Closes: 1002019 1005841 1006362 1006375 1006604 1008067
Changes:
debian-edu-config (2.12.18) unstable; urgency=medium
.
* etc/cups/cups-browsed-debian-edu.conf:
- Let TJENER's print queues appear on Debian Edu clients, use same
print queue names on clients as on TJENER. (Closes: #1005841).
* sbin/debian-edu-pxeinstall:
- Don't append 'ipappend 2' to the kernel boot cmdline anymore as it
confuses systemd when booting into the installed system. This resolves
the graphical.target not coming up on Debian Edu workstations that got
installed via the PXE/network based Debian Installer method. (Closes:
#1006362).
- Silence stderr output if the artwork theme lacks a plymouth subfolder.
This can be silently ignored and should not trouble Debian Edu admins.
* sbin/update-hostname-from-ip:
- Simply if-then-else-clauses, reduce number of exit calls, don't exit with
non-zero exitcode. Improve syslog messages if things fail. (Closes:
#1006604).
* share/debian-edu-config/squid.conf:
- Prefer DNSv4 lookups over DNSv6. Debian Edu does not yet fully support
IPv6 and many schools still use IPv4 primarily. This gives a great
performance boost to squid installations if IPv6 internet is not fully
available for whatever reason. (Closes: #1006375).
* share/debian-edu-config/tools/{update-proxy-from-wpad,wpad-extra}:
- Don't fail if proxy update is not possible, only send warnings to stderr
and syslog. Don't source wpad-extra script, execute it instead and
capture
stdout. (Closes: #1008067).
- White-space clean-up (use only tabs for indentation).
* Move /etc/debian-edu/host-keytabs/* to /var/lib/debian-edu/host-keytabs/
and replace directory /etc/debian-edu/host-keytabs by a symlink. (Closes:
#1002019).
* lintian: Update some override phrases (adjustments to the most recent
lintian version).
