Red Hat

Hi all,

I am not able to telnet from one system to another.

say from system1 to system2
However i am able to do

telnet system2 1521

but I am not able to do

telnet system2 6730 &
telnet system2 6731 &
telnet system2 6732

some other onformation:
system1:root(/root)# rpm -qa | grep telnet
telnet-0.17-39.el5
system1:root(/root)# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)
System2:root(/root)# rpm -qa | grep telnet
telnet-0.17-39.el5
system2:root(/root)# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)

telnet-server not installed on both system1 and system2


see below error
system1:root(/root)# telnet system2 6732
Trying 10.19.37.13...
telnet: connect to address 10.19.37.13: Connection refused
telnet: Unable to connect to remote host: Connection refused



However firewall on both sytem1 and system 2 are stopped.
I am able to telnet to another system (system2 from system1) on port 1521

Actually
I am not able to connect databases database1 (port no=6731), databse2 (port no=6731), VMdatabe3 (port no=6730), QAjki8 (port no=6732) on system2 server from system1. I was able to connect on port 1521 but not on other ports.

So how do I open these port,
In short How can make

system1]telnet system2 6730

(Currently it is showing connection refused)

work?



Please advice.
Thanks in advance

How much are you sure iptables is disabled on system2? Is there any external firewall sitting in between the two hosts? How sure are you about the configuration of the "databases"? Maybe it's not allowing connections to be established to those particular ports.

Need more information about the network you are on.
