Anyway I think SSH must be fixed on HostMonitor site, because new SSH mode breaks backwards compatibility.

And remind you: it's working on Ubuntu 12.04 without any issues (without "SSHMode=1"). I assume there are a lot of changes between Ubuntu 12.04 and 16.04 Also I think you have different versions of ssh servers on these systems. Two debug logs from SSHD in my post above were taken from the...

Maybe I should try SSHMode=1 on old servers to, to eliminate possible difference with "nohup" . I'll post results later today. SSHMode=1 does not work on "old" server. Process does not survive. I'll try with "setsid" too. "setsid" method works without "S...

So you have around 2000 tests related to this script (single script on single server)? It's same script on multiple servers. around 1500 tests in total. Then we have to find out what is wrong with this command nohup /path/to/binary -parameters & may be this version of "nohup" does not...

May be you can split it into 2 scripts? Make 2 tests, one will start "checking" script and wait for result, another dependent test will start 2nd script (start process). Regards Alex Assuming I split this single test into two, we have approximately 350 servers, each with 3 to 8 instances ...

What script? If HostMonitor starts "nohup /path/to/binary -parameters" command then I do not understand where is the script. Regards Alex What's not working: Background processes do not survive. Basically HM logs into system, checks if certain process is running and if not starts new inst...

Code: Select all

nohup /path/to/binary -parameters

This will not work. Removing ampersand would keep process running in foreground, this is not the very last command in our script, so this would effectively prevent script to complete the rest of checks.

New version available SSH test supports RSA keys (ssh-rsa). add SSHMode=1 line into [Misc] section Finally I've got my hands on new version and have done some tests. What's working: SSH tests now able to login and run commands on Ubuntu 16.04 just fine. What's not working: Background processes do n...

No, it will not provide log that can help. Have you tried latest HostMonitor? (please install it on different system or backup your config files - new version may convert your HML and LST files) Regards Alex Version 10.20 worked with minimal SSHD configuration change. At first I've got error: "...

I think you need HostMonitor version 10.14 or higher. Please check your license before update using menu Help->Update check Regards Alex Is there "debug log" in host monitor ? Is there a way to troubleshoot what exact problem there is with connection to new SSHD ? PS: I did "update c...

Hi, We use HM 9.84 now. Recently we started testing on Ubuntu 16.04 and it seems to be a problem with SSH tests. After we solved key exchange and incompatible cipher issues we've got weird error message on HM: "Protocol error. server refuses open channel" Please help us to resolve this iss...
