Our DBA has an application running on Server2 which needs to connect to Server1 (Linux OEL5.5 server) thru port# 9171. I use telnet to test basic connectivity. I performed the following on Server1, so far to no avail:
Server1# service iptables stop # to test, instead of creating a rule for the specific port# 9171, I completely stopped FW
Server1# I also disabled SELinux services on Server1
So, on Server1, there is NO FW, and NO SELinux.
Server2# telnet psapp01 9171
telnet: connect to address IP_address: Connection refused
telnet: Unable to connect to remote host: Connection refused
What should I do on Server1 in order to open up port#9171 for connection. Please advise; many thanks.
