talk command to chat
Hi,

Could you please advice on the following query:

There are 2 users on a unix box:
1. aaaa
2. bbbb

I open 2 putty sessions and login with the above 2 users.
Then I type the following using the aaaa user to chat with bbbb.

talk bbbb
or
talk bbbb@hostname

Result: the screen goes blank?

Any ideas, please?

Regards,
Girish.

I login to my windows desktop.
the I click on "start"-->"run" -->"telnet a.b.c.d x" to break firewall and get access to the server.

Both the users aaaa and bbbb belong to the same server.
I open 2 putty sessions and then i did what ever I had written in my 1st post.

chat using the write command is working fine though.

Talks is not very secure and disabled on many Unix systems. check whether talk is enabled on system. /etc/inetd.conf or xinetd.conf is fist place to look. If enabled and still not working try flushing firewall rules (iptables -F assuming Linux)

Hi Denny,

I could see the following entry in /etc/inetd.conf

[aaaa@xxxx] $ grep -i talk /etc/inetd.conf
ntalk dgram udp wait root /usr/lbin/ntalkd ntalkd

FYI, this is HPUX.

[aaaa@xxxx] $ which talk
/usr/bin/talk

[aaaa@xxxx] $ ls -ltr /usr/bin/talk
-r-xr-xr-x 1 bin bin 32768 Nov 14 2000 /usr/bin/talk


Regards,
Girish.
