I'm trying to install a Installation Server on a CentOS 7 but i'm facing some issues. After isntall the 9.0, Bundle 9.08 and the last patches i can with no problems import the IS on the Cell Manager.
When i try to upgrade some Linux RHEL clients that are in the 9.02 version, i receive the error:
"[Critical] <server.domain> [110:24] Client server.domain : client not responding."
But i can do a telnet to 5555 port to/from all servers ( IS, CM and Client ). The DNS are worked fine, with reverse resolution.
The SELinux and Firewall are disabled in the IS.
Please assign Kudos
Do you have ECC enabled in those clients?
omnicc -encryption -status -all
If this is enabled please disable it temporally upgrade clients and enable ECC again.
