Root Shell on FastIron

Post #1 of 4 (1661 views)

A while ago, I asked SE if it is possible to get Root Shell on FastIron
for diagnosis.
The answer was, that there is no possibility to connect low level.

Finally, I found out that this is not true and there is a possibility:

- Direct serial connection required
- If this is a non-master stacked unit: dm mport-enable to enable the
management LAN port
- go to OS mode with Ctrl+Y+M and Enter
- Now IP address can be set:
OS>remote address 172.20.1.10 255.255.255.0
- Gateway if needed:
OS>remote def 172.20.1.1
- Start telnet server:
OS>telnetd start
- Now you can connect via telnet to (additional and special) IP address
configured above. No authentication is taking place, root access.

Best regards,

Franz Georg Köhler

Because of the image size, the environment is very limited.
But there is a ftp client that we used to copy diagnosis files to the
outside.

Some more tricks. These are done from the boot loader ('b' on boot):
- 'setenv debug noautostart' - The box will not start FastIron OS and
will pause at a linux shell
- 'setenv quiet' - This nulls-out the quiet setting so you see Linux
boot messages
