xp to aix - telnet blank screen
hello,

i am trying to test connection to a 5.3 box. from an xp machine, telnet connects but shows only a blank screen. cursor moves as i type, but no response back.

have used telnet, putty and accuterm - all same result
verified that telnet services are active in xp
xp windoze firewall is off - service not started
set norton on the xp box to accept any protocol traffic from 5.3 box
verified that router is not blocking telnet or comms between the systems
verified that telnet services are active in 5.3
verified that aix is listening on port 23
verified inetd.conf, services and rc.net all look good

i can ping the 5.3 box from xp
i can ping the xp box from 5.3

telnet from the 5.3 box works to the xp machine - receive a logon
telnet from the xp machine to 5.3 connects, shows no logon or other characters

netstat -an|pg on the 5.3 box while telnet from the xp machine shows that the connection is established on port 23 on 5.3 box and port 3100 on the xp machine

any suggestions or info. on what i may be missing so that i can telnet from the xp machine to the 5.3 box and login successfuly is appreciated. once i can confirm this, i'll look into an ssh connection.

try telnet on to localhost on the AIX box to see if you do not have problems with telnet service on your server

Check that the router does inbound NAT for port 23 to 3100

Can you wait more than two minutes and see if a login prompt appears?

thanks for the replies

gito - yes, i had tried that and was able to do the localhost telnet - sorry did not mention that

frank - yes, I waited approx 15 minutes to rule out any negotiating delays and to see if it would time out - which it did - i also have the system set to timeout for inactivity

jgt - nat is enabled on the router - however, i did/do not see options for specific ports or a range of ports - i'll dig some more on that

1) Are you able to post the output from this command from BOTH computers, making it clear which is AIX and which is M$:
Code:
netstat -rn

2) Long shot
If the XP computer is a laptop and this is a wired LAN connection, make sure that the wireless is disabled.

3) Even longer shot
Whether disabled or not the Microsoft Windows XP Firewall is omnipresent. Enabling "telnet" on a totally disabled Microsoft XP Firewall could well do the trick. I've seen it work with FTP connections.

hey methyl,

xp machine is not a tower/desktop
yea - i've experienced the same where a disabled windows firewall is disabled but still mucking up connectivity - i set it to allow for telnet, no change

here are the results from netstat -rn for each system

Code:
aix 5.3 box
netstat -rn
