Connection Reset By peer

[sojeshj]

Hi,

I have a linux box where the Zabbix server is running. In the same network, there is another windows box, where the agent is running. Zabbix service on the windows box shows it is running. My server IP is 192.168.10.2 and the Windows client is 192.168.10.137. The zabbix_agentd.conf on Windows is given below. The problem I'm facing is the server show "Connection reset by peer" in the Host section of the admin configuration. It is listening on port 10050 and shows status as "Monitored", but availability is "Not Available" and Error shows "Connection reset by peer. Please help.

Also, the zabbix_agentd log on Windows box is as follows:
************************************************** ************
[17-Apr-2005 05:14:22] Log file opened
[17-Apr-2005 05:14:22] Collector thread initialized successfully
[17-Apr-2005 05:14:22] Zabbix Win32 Agent started
----------

I have also tried with port 10000 with no luck.

Please let me know what the issue might be.

Thanks,

Also, this is the server log (zabbix_server.conf):

----

001200:20050417:210100 Host [Bm.com] will be checked after [60] seconds

Please let me know if any of you have faced this issue and if so, what the fix for this issues is?

Thanks,

You set use ip ?

[Lovespider]

I posted the same problem here http://www.zabbix.com/forum/showthread.php?t=605
No one answered.
I've tryed changing the account the service use but no luck.

[sauron]

First use tcpdump for view zabbix activity.
Second i'm think zabbix try connected on bm.com ( 216.200.104.80 ).

[rickardp]

As Sauron said mark the checkbox in the host setting "Use IP address" for you host "Bm.com" and you are probably set to go.

Generally I try to connect using good old telnet to the agent on the agent port
"telnet 192.168.1.47 10050" and just quickly paste "version[zabbix_agent]" and press return (you got 5 secs to do it) and the agent will return the current version.

It's an easy first check to do.

[Lovespider]

Just to put this topic again on the top.
I tryed to telnet to the agent port but after passing the string, it shut down the connection (the infamous "connection reset by peer") like it was an error inside the agent.
Tryed with multiple admin users to start the service but nope.
Any suggestions about testing?

Do you have correct settings for Server in zabbix_agentd.conf?

[Lovespider]

Yes, I checked all the config files. I also checked the logs in verbose mode but it seems that the agent starts nicely but every query reset the peer.
Permissions are ok and also the basic services are running...I really don't know where to look at

You might want to check the following:

-do you use windows xp with sp2? If so, try disabling the firewall.

-check with with netstat -na wether the windows client does listen on the required port. zabbix uses tcp on default port 10050.

-do you use any other software firewall? If so, try disabling the firewall.

-did you set the server correct on the zabbix_agentd.conf?

also, the settings of your pid and logfile in the zabbix_agentd.conf are wrong!
on a windows box, you should not use:

# Name of PID file
PidFile=/var/tmp/zabbix_agentd.pid
# Name of log file.
# If not set, syslog will be used
LogFile=/tmp/zabbix_agentd.log

but something like c:\ etc.

Well, I got problems on Windows Server 2003 not XP so there is no firewall to disable BUT I made a Netstat -a and there is NO listener on the port of Zabbix (I defined 9535 to avoid other services).
This is a good step to start solving this issue...do you have any idea now, why the zabbix listener does not appear?
In the meanwhile I'll investigate more further in this directions.....

[Lovespider]

I reinstalled everything and now zabbix server says "Connection refused" but doing a telnet on that port and doing a quick paste of the version command now I got:

telnet xxx.xxx.xxx.xxx 10000
Trying xxx.xxx.xxx.xxx...
Connected to xxx.xxx.xxx.xxx.
Escape character is '^]'.
version[zabbix_agent]
ZBX_NOTSUPPORTED
Connection closed by foreign host.

I feel we are near the solution...

[Lovespider]

SOLVED!!
I managed to start this bloody server...
For the future:

1) check that server address in agentd.conf is correct
2) no matter the user you start the service in windows, it works
3) check the port into zabbix
4) with multiple NIC, try to force the binding address in agentd.conf

Millions of thanks to everybody for support and happy capturing!

Thank you for the summary of how you finally solved this
