open port 5555 and verify port is open

Gene Kenny — Fri, 23 Feb 2007 11:23:26 GMT

I am trying to open port 5555 for HP Data Protector

From a previous post is used the following command:
Service mgmt-vmware stop
Esxcfg-firwall --openPort 5555,tcp,in,HpDp6
Esxcfg-firwall --openPort 5555,tcp,out,HpDp6
Service mgmt-vmware restart

Then I try a netstat -a and I do not see 5555 listed
I tried ssh servername -p 5555 the response I get is ssh_exchange_identification closed by remote host. (Not sure what the response should be)

"lsof -i" and "netstat -af INET" should show if there is a port open, however if "iptables" is running it could be closing the port. Try running: "iptables -L" to see if the firewall is active.

Shalom,

By default iptables closes port 5555.

First try the connection with iptables down. Note that tcpwrappers can also block things.

iptables -A INPUT -s 192.168.0.55 --port 5555 -j ACCEPT

service iptables save

What the iptables statement does is accept input on port 5555 from 192.168.0.55 where that is the source ip address of the DP 5 system. Note the save statement will save that configuration past the next boot.

Hello Gene,

if you host is an ESX server, please use "esxcfg-firewall" to open the port for incoming and outgoing traffic. You _must_ use telnet, not ssh. Please try the following command

telnet hostname 5555

Then you should get a response from the Data Protector agent. You should try this from you esx to localhost and from you cellmanager to the dns hostname oder ip-adress of you esx server.

Regards,
Patrick
