Hi guys,
I just noticed that famous "Socket destroy delayed" message with 1.3.88 while experimenting with ICMP. Basically, I was ftp-ing a file via CSLIP nullmodem link and using nuke to send ICMP port 20 unreachable messages.
Here is what netstat(8) says:
saturn(tigran):/home/tigran/C/tcpdump> netstat Active Internet connections Proto Recv-Q Send-Q Local Address Foreign Address (State) User tcp 0 0 saturn.home.uk:1023 venus.home.uk:login ESTABLISHED root tcp 0 0 saturn.home.uk:ftp venus.home.uk:1032 ESTABLISHED root tcp 0 48180 saturn.home.uk:20 venus.home.uk:1034 ESTABLISHED root Active UNIX domain sockets Proto RefCnt Flags Type State Path saturn(tigran):/home/tigran/C/tcpdump> nuke venus saturn 20 Socket destroy delayed (r=0 w=268) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Also, have a look at tcpdump(1) output:
saturn:~# tcpdump -v ip proto 1 tcpdump: listening on sl0 18:48:40.545106 saturn.home.uk > venus.home.uk: icmp: saturn.home.uk tcp port 20 unreachable (ttl 64, id 3710) 1481 packets received by filter 0 packets dropped by kernel
So, the question is simple: why do I get this "Socket destroy delayed" on console?
Regards, Tigran.
