Not able to Telnet

[Atul Gautam]

Hi Xperts,

I'm not able to telnet my server.
I've got the following information for you people --


/etc/xinetd.d/telnet
---------------------

service telnet
{
disable = no
flags = REUSE
socket_type = stream
wait = no
user = sysadm
server = /usr/sbin/in.telnetd
log_on_failure += USERID
}

----------------------------

Logs say --

MLXILSFTP xinetd[14757]: libwrap refused connection to telnet (libwrap=in.telnetd) from
--------------------------------------------
[root@MLXILSFTP log]# service xinetd status
xinetd (pid 14354) is running...
[root@MLXILSFTP log]#
--------------------------------------------


What may be the possible cause of this....

Thanx in advance...

libwrap(TCP wraper) is used to restict access to server....
check and edit /etc/hosts.allow or /etc/hosts.deny

Hi Atul

Check your /etc/hosts.allow and /etc/hosts.deny

Edit these to allow telnet.

Atul,

Both responses given to you above are right, it's a secure shell feature, according to this HP doc, KBRC00011104

But I checked one thing, if at all I replace the line in "telnet" file--

user = sysadm

with

user = root

then only I'm able to get the login prompt, else it never prompts me or it gives me an error "Connection to host lost".

So, why do I need to specify user=root in it.


Thanks,

Atul

well man sais

user = root

it defines user ID which is running process with....

so it means, if your telnet server have some buffer overfolw vulnarability, than a pontetial hacker will get root rights... god with you...

so check your /etc/passwd if there is sysadm user, if not it, was maybe the problem...

try to create new user, or maybe on some distribution there is user called telnet... so try to run telnet server as this user...

user = telnet

anyway I would never use telnet... only device where I use telnet are old cisco which do not have ssh suport
