'Could not connect to RMI service' on WCM 2.1.0 & 3b

[goldpelican]

I've had a search of the forums, and this seems to be a common issue on Linux. When trying to deploy content from one Alfresco instance to another on Linux (Ubuntu 8.04), I get the following errors in the log:

17:11:03,680 WARN  [remoting.rmi.RmiProxyFactoryBean] Could not connect to RMI service [rmi://172.16.249.139:50500/authentication] - retrying
17:11:03,730 ERROR [avm.actions.AVMDeploySnapshotAction] org.alfresco.service.cmr.avm.AVMException: Could not Initialize Remote Connection to 172.16.249.139
‍‍‍

On the target machine (172.16.249.139), I get the following:

root@ubuntu-desktop:/opt/alfresco# lsof -i :50500
COMMAND  PID     USER   FD   TYPE DEVICE SIZE NODE NAME

Anyone got any ideas? At this stage it's a dealbreaker for Alfresco on Linux - I don't want to have to try and repeat this evaluation on Windows if it's Linux-specific.

It's likely that the problem connecting is due to the linux firewall.

I'm not that familiar with Linux but refering to the following web document.
http://wiki.linuxquestions.org/wiki/Firewall

How about running the command
iptables –list

to see whether there is a firewall on your Linux box?    
Then there may be some Linux administrators reading this that can help.

I'm now getting the identical error on a fresh build of Alfresco Labs 3b. I've deliberately cleared the iptables to ensure that there are no firewall issues, and I can both ping and telnet between the two VMs - telnetting to port 50500 is successful.

SURELY someone knows how to resolve this - it's a recurring problem in the forums and I can't be the only person trying to deploy between two Linux servers.

Hi
I have the same problem.
My configuration is: Ubuntu 8.04 on both servers, java sdk 1.5.0_15, Alfresco Enterprise WCM 2.2.
When i try to deploy from an alfresco instance to another, i get the follow error message:

WARN  [org.springframework.remoting.rmi.RmiProxyFactoryBean] Could not connect to RMI service [rmi://10.0.0.194:50500/authentication] - retrying
ERROR [org.alfresco.repo.avm.actions.AVMDeployWebsiteAction] org.alfresco.service.cmr.avm.AVMException: Deployment to 10.0.0.194 failed.

in this message i see that the sender server try to connect to receiver server as 127.0.0.1 and not with its network ip address…..
……Caused by: org.springframework.remoting.RemoteConnectFailureException: Cannot connect to remote service [rmi://10.0.0.194:50500/authentication]; nested exception is java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exceptio……..

if i try telnet on port 50500 it works!!

please help me

The 127.0.0.1 address is suspicious and led me to the following discussion on the web.
http://forums.sun.com/thread.jspa?threadID=5248497&messageID=10027310

Could you try adding the following java option to the command line starting Alfresco.

-Djava.rmi.server.hostname=x.x.x.x

Where x.x.x.x is your hostname?

[goldpelican]

Woohoo! Thanks mrogers!

I followed the supplied link - two things:

1. My hostname in /etc/hosts on both servers was still addressed at 127.0.0.1 instead of the machine's IP - fixed that
2. I started the "authoring" alfresco server with the -D option - after that, deployment was successful

Now I just need to figure out where the content ended up… I thought that perhaps a corresponding web project would have been created on the ASR, but there wasn't - I need to poke around in the ASR for a bit now to understand the deployment process.

cheers!
