Full Discussion: after patch, telnet not working
Operating Systems Solaris after patch, telnet not working Post 60293 by RTM on Friday 14th of January 2005 08:33:42 AM

Could you telnet before the patch? Do you really KNOW that you could telnet? Think about it - you are trying to figure out why your backup isn't working, not if telnet is working. Telnet may not have worked before.

Why does telnet work one way but not the other? Because one server doesn't allow it. First check the date on your /etc/inetd.conf file - see if it was changed by during the date you did the patch. Check your /etc/inetd.conf file on the server that does and the server that doesn't. Look for "telnet stream tcp" line - see if it starts with a # sign. If so, then it's commented out and won't work (probably a good thing).

Ufsdumps to a remote server usually use the /etc/hosts.equiv or /.rhosts files for allowing access - has nothing to do with telnet. Check the dates of those files and try to find out if and when they changed. I doubt the patch had anything to do with changing them.

in.identtestd

IN.IDENTTESTD(8)						 Library functions						  IN.IDENTTESTD(8)

NAME

       in.identtestd - a small daemon that can be used to test Ident servers

SYNOPSIS

       in.identtestd

DESCRIPTION

       in.identtestd  is  a  small daemon (to be started from inetd) that does an ident lookup on you if you telnet into it. Can be used to verify
       that your Ident server is working correctly.

       The source code can be found in the debian libident source package, as ident-tester.c.

EXAMPLE

       A typical entry in /etc/inetd.conf would be:

       9999 stream tcp nowait root /usr/sbin/in.identtestd in.identtestd

       With the above entry in place and active, execute "telnet hostname 9999" from either this system, or another system. It should  show  some-
       thing like:

	   Trying hostname...
	   Connected to hostname.
	   Escape character is '^]'.
	   Welcome to the IDENT server tester, version 1.9

	   (Linked with libident 0.22 Debian)

	   Connecting to Ident server at 192.168.1.1...
	   Querying for lport 1109, fport 9999....
	   Reading response data...
	   Userid response is:
	      Lport........ 1109
	      Fport........ 9999
	      Opsys........ UNIX
	      Charset...... <not specified>
	      Identifier... paul
	   Connection closed by foreign host.
