General :: Telnet Not Working For Localhost?
Apr 14, 2011I've tried searching for this peculiar behavior, but couldn't find a solution that works for it - I have installed Redhat on my system and have a listener running on port 7878. I wanted to check if the port is accessible from a machine on the network, and so i telnet-ed from a remote machine and it worked. Now comes the weird problem - I used the same command (telnet xxx.xxx.xxx.xxx 7878) locally and it was able to telnet. However, if I try to connect using localhost, meaning, "telnet localhost 7878" or "telnet 127.0.0.1 7878", it gives me the following error:
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused
Here is my /etc/hosts entry:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
[Code]....
Not sure where the problem is. I expect telnet to connect irrespective of whether i use the IP address OR localhost when i use telnet locally.

View 1 Replies View RelatedGeneral :: Automated Telnet For Testing Servers
Aug 20, 2009So I have a script that is supposed to check to see if a mail server is up and responsive. What I want to know is how I can send it the telnet escape character. I've tried:VAR=`(sleep 5;echo quit) | (telnet mailserver.timbuktu.net 25 2>&- )`
This works BUT there is a problem as the mail server may have been accidentally firewalled off. If this happens, my automated checking script will hang. What I want to do is send the escape character so that the '>' prompt comes up. They I should be able to send it "quit" even if it is hung on not getting a response from the server. VAR=`(sleep 5;echo -e '^]';sleep 1;echo quit) | (telnet arhqmg01.usarec.army.mil 25 2>&- )`
The above doesn't work. telnet interprets CTRL+] as '^]' but you can't type '^]' and get the same effect. So I guess what I need is to send the actual keystrokes. Like echo "somenumber" ; echo quit
General :: Disable Telnet And Ssh For A Specific User?
Nov 12, 2010I am looking for a way to deny telnet and ssh to one specific user. So far I've only tested with telnet and my attempts have been limited to various hosts.deny entries:
in.telnetd : user@server
in.telnetd : user@server.domain.com
in.telnetd : user@IP_address
in.telnetd : user@.domain.com
None of these work. The only thing I've found that does work is:in.telnetd : IP_addressBut this is only a semi-viable solution because we will soon have multiple logins for the one username from different servers and sub-nets. Ideally, I'd like to be able to deny telnet and ssh access to this username regardless of where the login originates. I suppose it would be possible to specify each server IP, but that'll be a bear to maintain
