Hello, "netstat -t -o" output sometimes looks like this: Proto Recv-Q Send-Q Local Address Foreign Address State Timer tcp 0 25024 localhost:18080 localhost:3763 ESTABLISHED unkn-4 (95.18/0/0) tcp 24128 0 localhost:3763 localhost:18080 ESTABLISHED off (0.00/0/0) and this connection appears to be stuck for several minutes (when the timer goes to 0, it starts again with long timeout a few times, the other two numbers after it remain 0, the Recv-Q and Send-Q numbers don't change). What is "unkn-4"? I've seen this first on two 2.4.3 machines, but it just happened on 2.2.19 too... Is this something to worry about? netstat is from net-tools 1.60-1 (Debian woody), not that old... It all happens after some time of ssh -L forwarding several TCP connections between squid proxies.
