Can I stop ToolTalk Service ? How can I do that ? I mean close port 49157

[Juan Manuel López]

For security reasons, We want to close the tooltalk port 49157, so I do not know how to do that.
Could anybody help me ?

Thanks in advance.

does disabling it in /etc/services not work?

[James R. Ferguson]

Hi:

You can comment-out the line in '/etc/inetd.conf' that references the 'rpc.ttdbserver'. Then restart 'inetd':

# inetd -c

Ok, so there in not a line with this port in /etc/services or /etc/inetd.conf.
Whatis the service name that open up this port ?

[Kofi ARTHIABAH · Accepted solution]

There will be an entry in your /etc/inetd.conf like :
rpc xti tcp swait root /usr/dt/bin/rpc.ttdbserver 100083 1 /usr/dt/bin/rpc.ttdbserver
comment that line out and reconfig the inetd daemon with
inetd -c

Good luck.

Thanks for your responses.
So please, I have not clear the tooltalk funtion. Can I stop this service ?
Xwindows and the rest of service will works properly ?

Thanks.

Juanma.

By the way for future purposes, the tool lsof (available from your nearest archiving and porting centre) is useful for find out things like what program is running on what port. you can use it to drill down to find out any mysterious programs that may be running on a mysterious port.

good luck.

Find out PID of the process on port 49157 w/ lsof; kill it at the command line;

# lsof -i:49157
# kill -9

Comment out these entries from the inetd.conf file...

rpc xti tcp swait root /usr/dt/bin/rpc.ttdbserver 100083 1 /usr/dt/bin/rpc.ttdbserver
rpc dgram udp wait root /usr/dt/bin/rpc.cmsd 100068 2-5 rpc.cmsd

...restart inetd

# /usr/sbin/inetd -c

cheers!

My notes show commenting the "rpc.ttdbserver" line in the /ec/inetd.conf file will not break CDE login from the console, Exceed or ReflectionX. However if you comment out this line then connection to another CDE desktop in order to exchange Calendar or DTmail info (dtcm and dtmail) will break.

I'd comment it out. Run inetd -c as mentioned above. You may also want to comment out the "rpc.cmsd" line. The CDE Calendar Manager (dtcm) will not work correctly but do you really need it?
