O am not able to install agents on 10.0.0.29 IP through opscenter. It says below error. The user is pavan and this user is having sudo access. Opscenter is unable to install the agents and I'm not able to use opscenter to monitor the cassandra nodes. I was able to remove tmp folder using sudo access of the user 'pavan' but I'm not sure what is missing here.

I went through question asked, but I could not get answer on this. Please help me to resolve this issue. Setting-up OpsCenter gives: scp /tmp/.. Permission denied

Installations Failed
Some agent installations failed:

- 10.0.0.29: Failure installing agent on 10.0.0.29.
Error output:
scp: /tmp/tmpZaSXoY: Permission denied

Exit code: 1

This was only affecting one of my servers, but I ended up installing "datastax-agent" through my package manager:

Debian: http://www.datastax.com/documentation/opscenter/5.0/opsc/install/opscManualInstallAgentPkgDeb.html

RHEL: http://www.datastax.com/documentation/opscenter/5.0/opsc/install/opscManualInstallPkgRpm.html
