Then at boot, at the linux boot line, issue the word single to force boot into single user mode. Then see if you can change the root password. Just remember to do a saveconf afterwards. Worst case, during boot you hit s and tell it not to use the alternate boot code and then after the ethernet tests are run hit esc and tell it to do a network boot. You just need to place a firmware image for the TS on a tftp somewhere (this might be difficult if you do not have access to the firmware load). Anyhow, all of this is explained in the manual... and I'm pretty sure you can find it somewhere online (even though this is incredibly old now). The problem with the TS's vs. the newer ACS units is that the flash is notoriously BAD. So, I'm sort of surprised that the TS-800 is even booting (mind you even with a bad flash, the TS COULD boot from network using that tftp server and load you have lying around). We ended up replacing most of our TS's with the newer ACS versions. They are still working. Had nothing but trouble with the flash on the TS-2000's.

Any idea how I can resolve this ? Edit /etc/passwd directly and insert a MD5 password hash (from some other host or mechanism you have) in for root and do a saveconf. Reboot and enjoy. However, with that said, I'm curious about the error.... might be that you have auth configured in /etc/portslave/pslave.conf to go to some kind of remote auth (NIS, LDAP, Radius, etc). So might have to look at that as well. |
