If mailman is not working make usre that mailmanctl (and its qrunners) are running.

On Linux, /proc/net/sockstat is like:

sockets: used 118
TCP: inuse 6 orphan 0 tw 21 alloc 8 mem 1
UDP: inuse 0
RAW: inuse 0
FRAG: inuse 0 memory 0

The "tw" above is for TIME_WAIT and could give some indication of DoS attempts. Or use "netstat -nta | grep TIME_WAIT | wc -l"

And /proc/net/netstat has more details. The first line has headers and second line is the corresponding values. For example, the first three are: "SyncookiesSent SyncookiesRecv SyncookiesFailed" but on my system they are "0 0 0". I was told this could be used to notice SYN flooding and other DoS attempts.

Committed changes to over 1200 pkgsrc and over 200 pkgsrc-wip files today! This is to change "RECOMMENDED" to more clear USE_ABI_DEPENDS and BUILDLINK_DEPENDS.$pkg to USE_API_DEPENDS. This was discussed on tech-pkg a month earlier.
