Port 6000 Process

Port 6000 Process

Post by Matthew Carl Schumake » Thu, 05 Aug 1999 04:00:00



Does anybody know a process that uses Port 6000, I was writing an app that
used that port and I could never get it, I tried telneting to it and I
connect but that was about it.  I'm running RedHat 6.0.  I looked in the
services file but there was nothing listed for that port.  I even tried to
reboot in case a previous process somehow didn't release it but it was
there when I rebooted which leads me to believe that its some sort of
system process, however my 2.0.36 machine has that port open.  Its not
that important since I can use any other port, Its just a little
disconcerning knowing that there is an app running on that port and I have
no idea what it is.

Thanks in advance

You can use 'lsof -i' to see which ports belong to which processes.

I did a "netstat -a -p" on my RedHat 6.0 system. Port 6000 showed up as
in use by my X Window server. I don't know if this is a normal part of
X or if it is Gnome. I just found something in the XFree86 docs, but
I don't really understand it. It says:

XFree86 listens on port htons(6000+n) where "n" is the display number.

I guess this is for non-local X clients to display on this system's
X display. Just my guess.

D*mn. Port 6000 is for X-windows display! If you are running
X-windows/gnome/xdmcp at all, of course you cannot get that port!
Use something else...

This is X server port for display :0. If you start another X-server,
telling it to be display :1 it would listen on 6001

If you start an X application on remote machine, telling it that it
should use DISPLAY=your.host:0, it would connect your machine's port
6000 and ask your X-server to draw its windows.

If you are worried about security of connection on this port, man xhosts
and man xauth should help you.

1. Connecting a process to a device on an RS/6000

Greetings,
  I sent this message out a few days ago, but I don't think it made it to the
outside world.  If it did, and this is the second time you're seeing this,
my apologies.

  I am looking for some programs that will allow a process to get
connected to a specific device.  Here's my situation.  I have
two RS/6000s, model 320s, and a model 550, all running AIX 3.1.
These machines are all on our campus Ethernet.  One unusual thing
is that there are only the two standard serial ports that come with
the machines.  All access to them for input and output is going to be
across the Ethernet.  All my users are miles away from my site.

The problem I am having is that they have lots of serial port printers
that they still wish to use.  What I'd like to do is take one of the
pseudo ports (those specified as pts/0 - pts/15), assign it to a
specific port on a terminal server at their site, and then attach
the printer to that port.  The user could then direct output to
that specific pseudo-port to get output to their printer.

  I do have a set of programs from Ross Cartlidge (called nd) that
do this type of connection for Suns and Mips machines, but I haven't
had any success in getting them to work with my 6000s.  They compile
fine, though I'm not sure how setpgrp is different between Sun/bsd
and AIX.

Does anyone have something that will allow the type of connection
I need, or can see a different methodolgy to use?  Any ideas are
greatly appreciated.
