AIX

I've an old server 1996 RS6000 (Processor 604e) running AIX 5.1.

It started up fine, booted up and connected on 10Mbit with my router. I used to be able to connect to it with telnet but not anymore. I know the IP is right but working with the smit tcpip options, looks like I've changed something as I can't access any of the ports.

I've two 9 pin serial connector adapters at the back that I presume are the HMC connectors in those days but I have no HMC to connect this desktop too on my end.

The only thing I have available for this system is a network cable and power cable. I don't have a keyboard or monitor for it nor a video card to hook up some sort of terminal to debug from the console. With IBM AIX being hardware specific, it's tough to find ones appropriate for IBM and such an old RS6000.

Is there any other way to get into the system now and recover from this?

A serial null modem cable hooked up to your pc serial port and running a terminal emulator on the pc is the way to go here - you may need a usb to serial adapter at the pc end if it is newer than mine...

That should give you enough key words to search for here or on the www.

604e and 5.1 suggests 9600,8,n,1.

hyperterm, putty, Etc. will do the "terminal emulator" bit for you.
