Hi there,
My ral0 in hostap mode works great, and has been for months. (Except for the
Nintendo Wii I posted about earlier, and I suspect the Wii.)
However, just now I ran into a problem. The ral is used in a server that
also has an Internet-connection. The server does NAT for the wireless
clients. I was uploading some photos from a wireless client to some
Website, and wireless traffic just stopped. The association was still
there, but from the wireless client nothing went through. Not even traffic
to the server itself. I then logged into the machine the ral0 interface
is in (using its console). Nothing in dmesg, but when I tried to ping the
wireless client, I got this:
ping: sendto: No buffer space available
ping: wrote 192.168.2.18 64 chars, ret=-1
Other traffic on the same server (using other interfaces) worked fine.
What can I do to more thoroughly investigate this, should this happen
again? It seems to be a very rare event, since it took months to even occur
once. I didn't think of anything more than to perform some netstat
commands, and check the number of states using pfctl.
netstat -m showed:
718 mbufs in use:
705 mbufs allocated to data
4 mbufs allocated to packet headers
9 mbufs allocated to socket names and addresses
87/128/6144 mbuf clusters in use (current/peak/max)
444 Kbytes allocated to network (79% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
netstat -an showed:
