[Pkg-libvirt-maintainers] Bug#564053: libvirt0: remote connection sometimes leaves netcat process on server side

[Vaclav Ovsik]

Package: libvirt0
Version: 0.7.5-2
Severity: minor

Hi,
this is a complement to bugreport #564034. Libvirt creates remote
connections using ssh & netcat (nc) and in some conditions
(interruption) netcat on server side remains forever.
I can reproduce this by bad URL a Ctrl-C after a while on virsh:

zito at bobek:~$ virsh -c qemu+ssh://root@aslan.i.cz/blablabla
^C
...several times...

aslan:~# pgrep -l -f 'nc -U'
27673 nc -U /var/run/libvirt/libvirt-sock
27813 nc -U /var/run/libvirt/libvirt-sock
27820 nc -U /var/run/libvirt/libvirt-sock
27829 nc -U /var/run/libvirt/libvirt-sock
27836 nc -U /var/run/libvirt/libvirt-sock

The code for execution netcat through ssh seems to be in
./src/remote/remote_driver.c.

Maybe the problem can be corrected on netcat on the other hand.

Thanks for time on maintaining the package!
Regards
