SCOM : Not enough entropy when installed Linux Agent
No comments · Posted by Christopher Keyaert in OpsMgr / Scom, PowerShell
Hello
When you try to deploy a SCOM agent on a Linux Operating System (most of the time a Virtual Machine) is possible that you get Failed to get random data – not enough entropy error message.
The message in details :
1 2 3 4 5 6 7 8 9 | Generating certificate with hostname="xxxxxxxx" [/home/serviceb/TfsCoreWrkSpcLinux_REDHAT_5.0_x86_64/source/code/tools/scx_ssl_config/scxsslcert.cpp:198] Failed to allocate resource of type random data: Failed to get random data - not enough entropy error: %post(scx-1.0.4-248.x86_64) scriptlet failed, exit status 1 type="Microsoft.SSH.SSHCommandData" time="2009-12-03T12:08:30.6908778+01:00" sourceHealthServiceId="91A3B596-F820-6A90-305C-6974DA25966D"><SSHCommandData><stdout>Generating certificate with hostname="xxxxxxx" [/home/serviceb/TfsCoreWrkSpcLinux_REDHAT_5.0_x86_64/source/code/tools/scx_ssl_config/scxsslcert.cpp:198] Failed to allocate resource of type random data: Failed to get random data - not enough entropy error: %post(scx-1.0.4-248.x86_64) scriptlet failed, exit status 1 |
Now, fixing the issue:
- clean off the partially installed agent using the commands
- rpm -e scx
- rm -rf /etc/opt/microsoft/scx
- Regenerate the random element
- rm /dev/random
- mknod -m 644 /dev/random c 1 9
- chown root:root /dev/random
- Rediscover the server from the SCOM Console and install the Agent
- After fixing the install issue, switch the /dev/random file back to a signed random file using the commands:
- rm /dev/random
- mknod -m 644 /dev/random c 1 8
- chown root:root /dev/random
