GSP config through HP-UX
Hi,
I recently moved a rp2410 to a remote site. I now cannot gain access to the gsp lan console.
I have managed to change the unix lan config through set_parms and can login to unix remotely.
Is there a way to access the gsp lan config from the unix login

Re: GSP config through HP-UX
#!/bin/ksh
# Exploits (?) a backdoor in HP-UX allowing access to the GSP without using
# the console or the GSP LAN device
# We expect the name of the host to access the GSP on to be $1
#EXIST=`$REMSH $HOST -l root ls /dev/tty1p0 2>&1`
ll /dev/tty1p0
if [ $? -ne 0 ]
then
/usr/sbin/mknod /dev/tty1p0 c 1 0x010000
fi
echo "use Ctrl-\c to exit"
/usr/bin/kermit -l /dev/tty1p0 -b 9600 -c

and got the response of:

Re: GSP config through HP-UX
The L3000:s and all rpXXXX-style servers seem to have either GSP hardware version B or C, or a more advanced MP/iLO instead of a GSP. These do not have this kind of internal port access. The ability to reset the password is arranged in a different way that requires you to use the *local* console for security.
I'm sorry, but it looks like you have to either travel to the site yourself or get someone you trust at the site to act as your "remote pair of hands".

Integrity uses MP. The GSP was for older PA-RISC boxes, as Matti_Kurkela said.

Re: GSP config through HP-UX
Since the GSP has the old address, you should be able to connect to the old address directly with a laptop, or perhaps with some switch vLAN setups. If not, then you need to reset the GSP with the button on the back and try the arp/ping method to set a new address. Depending the firmware version, the GSP may try to grab a DHCP address. You can check the DHCP server logs to see the assigned address. For the arp/ping method, you'll need the MAC address of the GSP port. Then using a PC, use a crossover cable to the GSP port (to avoid switch or DHCP issues) and run these commands:
arp -s <desired_new_GSP_IP_address> <MAC_address_in_PC_format> ping <desired_new_GSP_IP_address>
Then run telnet to connect to the GSP and you can then set the rest of the network values. Note that for newer Windows, telnet may have to be added from the Windows Features list.
The last method is to connect a serial crossover cable from the laptop to the 9pin console port.
Use ctrl-b to get the GSP's attention. Serial settings are 9600/8N1, no handshaking. No response probably means the cable needs a null-modem adapter to switch pins 2&3.
