Hi folks,
I'v got a question concerning the conntrack userspace tool. Each time I try to
delete an entry, conntrack displays the following error message (I'm using
the latest svn versions of both the userspace tool and the conntrack and
nfnetlink libraries):
>$:conntrack -D conntrack -s XXX.XXX.XXX.XXX -d XXX.XXX.XXX.XXX -i XXX
>NFNETLINK answers: No such file or directory
>Operation failed: such conntrack doesn't exist
Is my syntax for deleting correct? The error message appears each time,
regardless of what ip addresses I use (i.e. regardless if the ip addresses
belong to an existing conntrack entry).
An strace of the command listed above brings up the following:
> strace conntrack -D conntrack -s 134.96.60.203 -d 62.178.187.30 -i 983

Could anybody please help me out?
