TIME_WAIT Assassination in FreeBSD???

[Jarrod Lee Petz]

Hi Doug,

The problem itself is currently seen on AIX yes.

However, I am more after.

1. Insight into the TCP/IP stack. Is it broken here?

2. Insight into whether active FTP is flawed in design? Or perhaps just
this implementation of it? Solution is to use passive FTP which seems fine.

3. Would FreeBSD have the same issue? According to RFC6056, FreeBSD uses
"algorithm 1" which "is biased towards the first available port after a
sequence of unavailable port numbers." So unless it does something fancy
like TIME_WAIT assassination. I think it would behave similar to AIX when
doing multiple active FTP data connections & encounter the same issue.

Regards Jarrod

It's not clear to me what the FreeBSD related problem is here.
