Yesterday I've tried to send the content of a file via netcat to
a remote host. So I set up the nc on the remote host to listan
on port 10004:
root@tigger /tmp # nc -v -p 10004 -l
listening on [any] 10004 ...
Than I go to the NetBSD system and do a:
root@rabbit /tmp # uname -a
NetBSD rabbit.badphish.dyndns.org 1.6.1 NetBSD 1.6.1 (RABBIT) #0: Thu Nov 2=
7 23:02:51 CET 2003 email@example.com:/usr/src/sys/arch/i=
root@rabbit /tmp # cat tindny-09-Dec-2003.log | nc tigger 10004
No problem so far ... until cat reaches the end of the file.
The nc process on rabbit continues to read from stdin.
I can see the last line of the file on the remote side
but the connection wont be closed and the command line from
the sender (rabbit) still remains "active".
If I login to another system (not NetBSD) and try the
cat ... | nc ... command everything works fine and
the nc process terminates if cat is done with the file.
Works fine on OpenBSD 3.4, FreeBSD 5.1 and Linux 2.4.22
and 2.6.0-test11. The netcat version is the same on every
system. It is v1.10 (nc -h says so) and the file I read
via cat is a regular file.
Is there anyone out there who can point me to the solution?
Many thanks in advance.
