[Users] Debian 7 HN Repository

[Johan Wilfer]

Hello again,

I've run my Debian 7 HN for some days now, and it seems to be working 
well. I've some glitches - all are described below. Also are my 
work-arounds described.

Thansk for this new Debian 7 reprository! :-)

When I try to load module xt_tcpudp I get an error. As my iptables-rules 
seems to be working anyway this isn't a big issue for me. This module 
can be loaded with the Debian 3.2-kernel however.

# modprobe xt_tcpudp
libkmod: ERROR ../libkmod/libkmod.c:505 
kmod_lookup_alias_from_builtin_file: could not open builtin file 
'/lib/modules/2.6.32-openvz-042stab081.3-amd64/modules.builtin.bin'
FATAL: Module xt_tcpudp not found.

OpenVZ kernel seems to be loading /etc/sysctl.conf before the network on 
boot. The result is that network-params are not applied. This is printed 
on boot:

sysctl: cannot stat /proc/sys/net/ipv6/conf/all/accept_ra: No such file 
or directory
sysctl: cannot stat /proc/sys/net/ipv6/conf/all/autoconf: No such file 
or directory
sysctl: cannot stat /proc/sys/net/ipv6/conf/default/accept_ra: No such 
file or directory
sysctl: cannot stat /proc/sys/net/ipv6/conf/default/autoconf: No such 
file or directory
.
.

My quick fix is to run "sysctl -p" in /etc/rc.local as it executes last.

Do you want bugreports at the tracker of these issues?
(Also, there are two issues in the mail below)

Thanks!
