Hi all
I have two oddities with ss command (from iproute2 package)
linux kernel 2.6.8.1, SMP on x86_64 ss -V ss utility, iproute2-ss040823
1) It seems TCP sockets in SYN-RECV are not displayed at all.
ss state syn-recv
Recv-Q Send-Q Local Address:Port Peer Address:Port
<nothing>
2) It seems not all tcp sockets are fetched/displayed on a very loaded server.
# ss -an|wc -l ; cat /proc/net/sockstat 565859 sockets: used 611269 TCP: inuse 613140 orphan 2572 tw 4747 alloc 613820 mem 116376 UDP: inuse 7 RAW: inuse 0 FRAG: inuse 1 memory 544
You can see on this sample that ss -an displayed 565859 lines, but /proc/net/sockstat correctly said that more sockets were used.
Of course, /proc/net/tcp on such machine is not an option (never completes), so I cant list all connections for this machine. I really *need* a working ss command.
Are they known problems ?
Thank you
