------- Additional Comments From Allanon@tiscali.it  2002-12-30 15:17 -------
This is the last part of the output from a "strace -f -p <pid>" on connect.

Before SIGHUP:

[pid 13019] write(1, "220 FTP Server ready.\r\n", 23) = 23
[pid 13019] setsockopt(0, SOL_SOCKET, SO_OOBINLINE, [1], 4) = 0
[pid 13019] setsockopt(1, SOL_SOCKET, SO_OOBINLINE, [1], 4) = 0
[pid 13019] getpid()                    = 13019
[pid 13019] fcntl(0, F_SETOWN, 13019)   = 0
[pid 13019] getpid()                    = 13019
[pid 13019] fcntl(1, F_SETOWN, 13019)   = 0
[pid 13019] select(1, [0], [], NULL, {60, 0}

After SIGHUP:

[pid 13090] write(1, "220 FTP Server ready.\r\n", 23) = -1 EBADF (Bad file 
descriptor)
[pid 13090] setsockopt(0, SOL_SOCKET, SO_OOBINLINE, [1], 4) = 0
[pid 13090] setsockopt(1, SOL_SOCKET, SO_OOBINLINE, [1], 4) = -1 ENOTSOCK 
(Socket operation on non-socket)
[pid 13090] getpid()                    = 13090
[pid 13090] fcntl(0, F_SETOWN, 13090)   = 0
[pid 13090] getpid()                    = 13090
[pid 13090] fcntl(1, F_SETOWN, 13090)   = 0
[pid 13090] select(1, [0], [], NULL, {60, 0}

If you want I can attach the whole output...

I can confirm this behaviour does exist on 1.2.8rc1 too: the only diff
is that I can digit the username, than the server hangs as on 1.2.7:

[root@zx ~]# ftp 0
Connected to 0.
220 FTP Server ready.
Name (0:allanon): test

.. and the server does not respond anymore ..
