vCenter Appliance 5.1 U1c can't telnet port 902

Hello,

I can't telnet vCSA v5.1 U1c on port 902. No Firewalls involved.

How can I check, which service failed via SSH?

Thanks,

Thorsten

What does it say when you telnet?

A firewall may be blocking that port from your source to the destination server.


These ports are mandatory:

  • 22 - SSH (TCP)
  • 53 - DNS (TCP and UDP)
  • 80 - HTTP (TCP/UDP)
  • 902 - vCenter Server / VMware Infrastructure Client - UDP for ESX/ESXi Heartbeat (UDP and TCP)
  • 903 - Remote Console (UDP)
  • 443 - Web Access (TCP)
  • 27000, 27010 - License Server (Valid for ESX/ESXi 3.x hosts only)

These ports are optional:

  • 123 - NTP (UDP)
  • 161, 162 - SNMP (UDP)
  • 88 - Kerberos (UDP and TCP)
  • 464 - Active Directory (TCP and UDP)
  • 3260 - Software iSCSI (TCP)

For a complete list of ports, see TCP and UDP Ports for vCenter Server, ESX/ESXi hosts, and other network components management access....

Yours, Oscar
