[hylafax-users] Error: (127.0.0.1,4558): Address already in use.

[Daryl Sayers <daryl@ci.com.au>]

I am using hylafax-4.1.b2 running on FreeBSD 4.5. We have had this
running for many months and have only had 1 problem that has appeared
many times. I believe that hylafax uses an ftp style that uses a back
channel for data. Is this what 4558 is used for??

The error is:

425 Cannot create data socket (127.0.0.1,4558): Address already in use.

On doing a netstat -a | grep 4558 I see that one of my many NCD
X-Terminals is now connected through port 4558.

bash-2.04# netstat -a | grep 4558
tcp4       0      0  localhost.4558            di205.x11              ESTABLISHED

Now I am not versed in the runnings of tcp and the kernel but I thought
reserved ports went to 1024 and the rest are up for grabs in a dynamic
pool. If this is the case, how can hylafax expect to have 4558 available
all the time. Is there a workaround for this.
