I've created an internal bug to investigate SELinux on RHEL 6.0 further. If we need any further information we will update this forum post.</p> <p>Thanks for the bug report! </p> http://www.datastax.com/support-forums/topic/unable-to-install-remote-agent-couldnt-get-fingerprint-for-ssh-key#post-1945 Sat, 19 May 2012 16:53:31 +0000 Anonymous 1945@http://www.datastax.com/support-forums/ <p>I've been able to resolve the problem, and now all agents are working - thanks for your help. The situation was that I'd disabled SSL while working on an earlier agent connection problem. Uninstalling and reinstalling the agent restored the default SSL settings, leaving the agent trying to use SSL to connect to an opscenter that was not using it.</p> <p>I appreciate very much your prompt and helpful responses. Your suggested workaround of disabling SELinux during the agent install was the key to resolution. I'm a little concerned that this was necessary, and if you need anything more to diagnose it, I'll be happy to provide it. However, my original issue is resolved. </p> http://www.datastax.com/support-forums/topic/unable-to-install-remote-agent-couldnt-get-fingerprint-for-ssh-key#post-1943 Sat, 19 May 2012 01:05:32 +0000 nickmbailey 1943@http://www.datastax.com/support-forums/ <p>Thanks for the additional information. </p> <p>Regarding the install from the UI not working, do you know if the agent process managed to start? There are two places I would look for errors. '/var/log/opscenter-agent/installer.log' will contain the log of the installation process. If that appears normal then the normal agent log '/var/log/opscenter-agent/agent.log' should hopefully indicate any communication problems if the install succeeded and the process started.</p> <p>Any errors from those logs will help us debug, but obviously if the manual installation is working for you, you can continue to use that. </p> http://www.datastax.com/support-forums/topic/unable-to-install-remote-agent-couldnt-get-fingerprint-for-ssh-key#post-1942 Sat, 19 May 2012 00:57:17 +0000 Anonymous 1942@http://www.datastax.com/support-forums/ <p>I had already installed the agent manually, but uninstalled it with </p> <blockquote><p>yum opscenter-agent erase</p></blockquote> <p>and cycled opscenter.</p> <p>This restored the problem. Here is additional context from the failed install:</p> <blockquote><p> 2012-05-18 17:42:47-0700 [CA_APM] INFO: Beginning install of OpsCenter agent to 138.42.81.221<br /> 2012-05-18 17:42:47-0700 [] couldn't get fingerprint for SSH key ('ssh-rsa', 'AAAAB3NzaC1yc2EAAAABIwAAAQEA3TgMr2NFv5HI5m++1ycFrJE75h6NPRW/Bg+RoMTF68jhgbr8TBRpO43gntPc5WA+CyTEV3Jj9P+xfMVccP2q/+uqHYqZU3fYxFn3Dm2WpuZh0Q8E3v7yNOolsOUarc0pZ6iFeQnaOcIv7lc9xNFURsDkcJgACejnPN9YRvozCdWw0HyzkDDLuO2HAlpySSeSk1y1mj5PEctyvMQ7o+3SIIueykiUcqelCMDFEFMvZENtWkb6TbsytTFjLg6GoWFUgImUFrrT390svSx0inz1OVl9LNpx6C0SZAuCD+FD8y7Yw6puE3TCneaP2hh3N4W6c6XTlkICqnLWZ7wTNbkxrw=='):</p> <p> /usr/share/opscenter/tmp/tmp0tSgtF: Permission denied<br /> Traceback (most recent call last):<br /> Failure: twisted.internet.error.ProcessTerminated: A process has ended with a probable error condition: process ended with exit code 1. </p></blockquote> <p>I then tried your suggested workaround, and it appeared to work - the agent install finished successfully.</p> <blockquote><p> 2012-05-18 17:47:01-0700 [CA_APM] INFO: Beginning install of OpsCenter agent to 138.42.81.221<br /> 2012-05-18 17:47:32-0700 [CA_APM] INFO: Install of OpsCenter agent to 138.42.81.221 complete </p></blockquote> <p>However, opscenter didn't detect the agent, even after a recycle. I tried - and succeeded - in installing it a second time, and also recycled opscenter. It still cannot detect the agent (the opscenter console still states "1 of 2 agents connected" and shows a "Fix" link. The missing agent is on the opscenter server box itself. </p> http://www.datastax.com/support-forums/topic/unable-to-install-remote-agent-couldnt-get-fingerprint-for-ssh-key#post-1941 Fri, 18 May 2012 17:59:27 +0000 nickmbailey 1941@http://www.datastax.com/support-forums/ <p>Have you tried installing the agents again since running the chcon command? Assuming it is still failing, attaching more context from the failure in the log may help.</p> <p>As a temporary workaround I believe you can disable selinux temporarily in order to install the agents. 'setenforce 0' should accomplish this. You may also need to restart the OpsCenter process. </p> http://www.datastax.com/support-forums/topic/unable-to-install-remote-agent-couldnt-get-fingerprint-for-ssh-key#post-1932 Fri, 18 May 2012 00:18:28 +0000 Anonymous 1932@http://www.datastax.com/support-forums/ <p>SELinux is enabled. The chcon command you suggested gave no response, so I added the -v argument:</p> <blockquote><p> [root@bvdl-vm-01 cassandra]# sestatus<br /> SELinux status: enabled<br /> SELinuxfs mount: /selinux<br /> Current mode: enforcing<br /> Mode from config file: enforcing<br /> Policy version: 24<br /> Policy from config file: targeted<br /> [root@bvdl-vm-01 cassandra]# which chcon<br /> /usr/bin/chcon<br /> [root@bvdl-vm-01 cassandra]# which setenforce<br /> /usr/sbin/setenforce<br /> [root@bvdl-vm-01 cassandra]# chcon -vt ssh_home_t /usr/share/opscenter/tmp<br /> changing security context of `/usr/share/opscenter/tmp' </p></blockquote> http://www.datastax.com/support-forums/topic/unable-to-install-remote-agent-couldnt-get-fingerprint-for-ssh-key#post-1930 Thu, 17 May 2012 01:30:47 +0000 nickmbailey 1930@http://www.datastax.com/support-forums/ <p>This also sounds like a problem with SELinux in RHEL 6.0. Can you confirm if SELinux is enabled or not?</p> <p>Assuming it is running can you run the following commands and post the output:</p> <p>which chcon<br /> which setenforce<br /> chcon -t ssh_home_t /usr/share/opscenter/tmp</p> <p>That last command is the command that should have been run during install to enable the correct SELinux permissions on the directory. The first two commands will help us debug why it may not have worked. </p> http://www.datastax.com/support-forums/topic/unable-to-install-remote-agent-couldnt-get-fingerprint-for-ssh-key#post-1927 Wed, 16 May 2012 23:29:50 +0000 Anonymous 1927@http://www.datastax.com/support-forums/ <p>I am having the same problem on RHEL 6.0.
