Hi, We have the following environment:
Cell manager - windows 2008 r2, running DP 8.1
Client - Linux Centos 6.5, with installed disk agent.
The client was successfully imported into the cell. The issue is that when we try to expand its objects from "Backup Tab" the following error pop's up:
"ipc invalid hostname or ip address" - screenshot attached
Also when we try to start the backup it fails with the following error:
[Critical] From: BDA-NET@client3.domain.com "client3.domain.com [/CONFIGURATION]" Time: 6/2/2014 12:25:02 AM Cannot connect to Media Agent on system cellserver1.domain.com, port 56324 (IPC Invalid Hostname or IP Address) => aborting.
We have Successfull ping and telnet on port 5555, via IP and FQDN between the client and the cell.
Any assistance identifying the issue will be well appreciated. Thank you in advance!

In the Error message, this is the key thing to look at
[Critical] From: BDA-NET@client3.domain.com "client3.domain.com [/CONFIGURATION]" Time: 6/2/2014 12:25:02 AM Cannot connect to Media Agent on system cellserver1.domain.com, port 56324 (IPC Invalid Hostname or IP Address) => aborting
For some reason, this p[ort is being blocked. This has all the signs of trying to backup through a firewall. After initial connection is made between teh Cell manager, Disk Agent and Media Agent using port 5555, then DP uses Dynamic Port Addressing to use whatever port is available, in ths case port 56324 was chosen
You have to create a firewall rule on the disk agent to allow a range of ports to be used for the backup, then you have to edit the file
Disk Agent (Linux)
Media Agent (Windows 2008)
Program Data -> Omniback -> omnirc
and add the line
where "[start]-[finish]" represents the range of ports set by the firewall rule, so for example
After saving the file, on Windows systems, DP INET service must be stopped and started
This must be done on BOTH the disk Agent and Media Agent
In the GUI, if you click on Help -> Help topics, and enter OB2PORTRANGE is the search string, there will be much more extensive discussions on this topic. Also, if the DP 5.5 Admin Guide (the last version for which the Admin Guide was published)
The 'omnirc' file and Firewall support are als well-explained

Thanks for your reply. Unfortunately the issue still persist:
What i did is :
1.The following configuration of iptables file were applied and saved after that:
:INPUT ACCEPT [942:170492]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [312:91583]
-A INPUT -p tcp -m state --state NEW -m tcp --dport 5555 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 40000 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 40000:40020 -j ACCEPT
-A OUTPUT -p tcp -m state --state NEW -m tcp --sport 5555 -j ACCEPT
-A OUTPUT -p tcp -m state --state NEW -m tcp --sport 40000 -j ACCEPT
-A OUTPUT -p tcp -m tcp --dport 40000:40020 -j ACCEPT
2.Added following entry was added in omnirc file of the client and the host:
The client started to use the defined ports, but still fails with the same error.
3.The client and the cell manager were rebooted.
It seems that there is an issue with the Firewall of the client, but even with the configuration mentioned above it

Hello Bob, the issue was solved. The error appeared, because CentOS could not resolvse itself like windows.
We just added an entry in /etc/hosts with its ip address and FQDN.
Anyway thank you for you help.
