Hi, thanks for the answer
Here is what you asked for:

# netstat -aln | grep 22

Note that I already tried to only listen on igb0 interface
(192.168.9.60) in sshd_config, but the results are exactly
the same described below.

I'll get back to you regarding link aggregation when I'm done with groceries.
We use it here in production and it works flawlessly.

No answer, so it seems that link aggregation doesn't really work in freebsd,
this may help others with the same problem...
I reverted back to one link for management and one for service, and ssh
works as it should...

Scenario : freebsd 9 stable (yesterday) amd64 on HP server with 4 nic (igb)
1 nic is connected standalone to the management switch, the 3 other nics
are connected to a switch configured for aggregation.
If I configure the first nic (igb0) there is no problem, I can operate
as I normally do and sshd functions normally.
The problems start when I configure the 3 other nics for aggregation:
in /etc/rc.conf
...
ifconfig_igb1="up"
ifconfig_igb2="up"
ifconfig_igb3="up"
cloned_interfaces=lagg0
ifconfig_lagg0="laggproto lacp laggport igb1 laggport igb2 laggport igb3
192.168.12.7/24"
...
I restart the server and the aggregation seems to work correctly, in
fact ifconfig returns the correct lagg0 interface with the aggregated
links, the correct protocol (lacp) and the correct ip address and the
status is active. I can ping other IPs on the aggregated link.
Also the other (standalone) link seems to work correctly. I can ping
that address from other machines, and I can ping other IPs from that
server.
DNS lookups work ok too I can also use telnet to connect to pop3
servers so there seems to be no problem on the network stack.
But if I try to connect to the sshd service on that server, it hangs
indefinitely. On the server I find two sshd processes:
/usr/sbin/sshd
/usr/sbin/sshd -R
There is no message in the logs.
If I try to kill sshd (/etc/rc.d/sshd stop) I can't. it just stays there
forever waiting for the pid to die (it never does)
Even ssh client doesn't seem to work. In fact, if I try to connect to
another server, the ssh client may start to work correctly, then soon
or later it just hangs there forever, and I can't kill it with ctrl-c.
No firewall is configured, there is nothing else working on this server.
Thanks for any suggestions...
