I am not sure what your "standard procedure" was, so I can't really comment on what specifically needs to be done differently. Telnet on all current production versions of Power PMAC is disabled on the factory image, as it is not considered “secure” communication. Re-enabling this is a “Linux task” and would be outside of the scope of technical support. Also, note that the Linux commands to execute this could “brick” the firmware easily if done incorrectly. Use “SSH” communications instead (fully supported in the PDK and IDE).

That said, please see attached for our generally recommended procedure.

Hello sir,

Thankyou for your valuable feedback, we  tested the cmds and found the following 



A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using  -L label  or by uuid, using  -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say  man 8 mount .
system rm /etc/resolv.conf
rm: cannot remove '/etc/resolv.conf': No such file or directory
system rm /.readonly/etc/resolv.conf
system cd /.readonly/etc/xinetd.d
system mv telnet.disable telnet
mv: cannot stat 'telnet.disable': No such file or directory
system /etc/init.d/xinetd restart
Stopping internet superserver: xinetd.
Starting internet superserver: xinetd.
system mount -o remount,ro


Also find the attached file FYR! (LINUX)
