How to enable Telnet in IBM Bladecenter AMM
- 0 Comments
Now a day’s nobody like to use telnet on their datacenter server but every now and then you have to use telnet. I start looking into telnet while working on xCAT setup.
The xCAT is cluster administration toolkit which is open source cluster and is a great resource for provisioning IBM blade servers. Since xCAT is open source it is free to use but there isn’t a good support available online. When I start configuring xCAT I realized after setting up all settings for AMM and blades in chassis I couldn’t execute remote (rpower) command, looking closely in rpower script I realized it is using telnet to connect to AMM.
I was getting connection refused error from xCAT while running rpower command because telnet was disable on IBM AMM.Here is how I enabled telnet which fixed my xCAT issue :
To enable telnet (the less secure option)
- From AMM web browser console navigate to IBM AMM Control -> Network Protocols
- Scroll down to Telnet Protocol
- Enable Telnet mode using the drop down box
- Save the settings.
You should be good to go but wait you need to restart the AMM to make this change effective. Note: The SSH and Telnet services can be assigned to non-standard ports in the IBM BladeCenter. This can be checked under AMM Control -> Port Assignments.
