I noticed a strange behavior some days ago, but I can't say how much long it
have been happening for. Some processes which are running in different jails
on the same host seems to be listening on all host IPs. Here is an example:
#sockstat -4l | grep "4 \*:"
root mDNSRespon 69801 3 udp4 *:45258 *:*
root mDNSRespon 69801 4 udp4 *:5353 *:*
root unfsd 69761 3 udp4 *:2049 *:*
root unfsd 69761 4 tcp4 *:2049 *:*
root rpcbind 69703 7 udp4 *:111 *:*
root rpcbind 69703 8 udp4 *:732 *:*
root rpcbind 69703 9 tcp4 *:111 *:*
921 transmissi 29851 10 udp4 *:* *:*
931 asterisk 29805 25 udp4 *:* *:*
It's happening on several host right now (all are running FreeBSD/amd64
8.2-RELEASE-p5), with both UDP and TCP listeners. Any jail is using a single
unicast IP address. I really hope to miss something important... or should I
guess that these processes are "escaping" from the jails?! :S
Thank very much for any explanation anyone would be so kind to give me.
Andrew
