Title:
No tcp_keepalive_time in LXD container
Status in linux package in Ubuntu:
Incomplete
Bug description:
Using LXD v2.20 on Ubuntu 16.04 host, with kernel
Linux 4.4.100-mainline-rev1 #1 SMP Tue Nov 21 08:44:48 UTC 2017 x86_64 x86_64
x86_64 GNU/Linux
I get the following
# cat /proc/sys/net/ipv4/tcp_keepalive_time
cat: /proc/sys/net/ipv4/tcp_keepalive_time: No such file or directory
I'm informed from linuxcontainers.org, that this is a kernel bug.
https://discuss.linuxcontainers.org/t/why-is-there-no-tcp-keepalive-under-lxd/891
I happen to be trying to run Kolab.org in a container, and some of their
python code errors as this is parameter is not found. Clearly someone has found
this in Kolab before as there's a patch
https://github.com/TBits/KolabScripts/blob/KolabWinterfell/kolab/patches/fixPykolabIMAPKeepAlive.patch
But the problem is in other places too.
It could be argued that Kolab should code round this issue.
But on the other hand, with out it, and in general, other applications would
not run in containers, which perhaps is a undesirable limitation.
Thus it's why I'm reporting here.
And there may be other parameters not appearing in the container too.
