Services reported as 'down'

[live2]

i have fixed the problem

check you sshd_config if have a ListenAddress configured.

Add this line ListenAddress 127.0.0.1

zabbix open a connection to 127.0.0.1 to check the ssh service.

command
ssh 127.0.0.1

I have the same problem and setting ssh for localhost listen doesn't work. it looks like zabbix didn't understand names of services cuz if I send "proc.num[sshd]" key, it shows me real count of ssh daemons process, but trigger key is "net.tcp.service[ssh]" and it shows only zero, if I send "net.tcp.service[sshd]" it tells me ZBX_NOTSUPPORTED.
OS: CentOS 5.4 x64

I have a similar problem except it is on a computer other than the server. I have a computer that has SSH reported as down in zabbix but it clearly shows as running on the process table of the machine and I can use an SSH connection to login to the computer in question. Yet zabbix reports the service as down. I have several other computers monitored by this same zabbix server and none of them including the server itself are reported as having ssh down. I'd really like to see if someone ends up figuring out what is happening here. I'll watch this thread.

In my options it was problem in agent-server incompatibility cuz I took them from different reposes.

Hmmm... I definitely have multiple computers running the exact same agent version. This is a problem only on one computer with all my other computers correctly reporting ssh as running.

NOTE: The 64-bit agent would not run on computer1 or computer2. Nor would the 2_6 version. The 2_4 version would run and on computer2 has been successfully reporting status for a long time. On computer1 the agent is successfully reporting status in every way except that it thinks ssh is down when it is running fine.

maybe you need to build agent from source using x64_86 library's
on what arch working server? x64_86 or х86?

Thanks for the help so far. I compiled the agent on the machines in question and I still get the "ssh server is down" message on all three of the computers that have been having this problem. All of the rest of my computers are happy with their ssh servers it seems. It is strange as these three computers seem to have nothing particularly unique or in common about them. They share many characteristics with other computers that are working fine.
