-
- depends on what you mean by "normal". our gopher server, a sun 4/490
- running 4.1.1, has lines like
-
- tcp 0 176 ural.gopher gork.glyph.zak.edu 16224 CLOSING
-
- in its netstat -a output. They stay there forever. This prevents me from
- killing and restarting (a new version of) gopherd.
-
- is this a bug in the TCP implementation that does not properly close a
- TCP connection after a timeout?
-
- i've seen similar things with nntp connections originating from a
- particular (broken?) newsreader, on an ultrix machine.
-
- anyway, i think a TCP server should be able to close a TCP connection
- cleanly even with mis-behaving clients.
