How to telnet from ESX host

How to "telnet" from ESX host to check for port connectivity

If the ESX server isn't having telnet installed, follow the steps below:

1) Put the ESX CDROM into the server.
2) Type:  "mount /mnt/cdrom"
3) Type:  "cd /mnt/cdrom/VMware/RPMS"
4) Type:  "rpm -Uvh telnet-0.17-26.EL3.3.i386.rpm"
5) Enable the Telnet outbound firewall port


Search for the rpm file "telnet-0.17-26.EL3.3.i386.rpm" from the below link and download appropriate file for the OS.

and run the command

"rpm -Uvh file_name.rpm"

for example,

"rpm -Uvh telnet-0.17-26.EL3.3.i386.rpm"

If the telnet is already installed, ignore the above steps.

To check for the port connectivity, run the below command:

telnet ip_address port_id

for example,

telnet 1918
