Last week I upgraded from a 1.0.1 snapshot release (embedded) to
1.2beta1 5/9/2007 snapshot using the rc.firmware script. The upgrade
installed nicely and everything seemed to work well (aside from
having to manually fix gettytab and put the ttys_wrap file in place
of ttys).
However, for some reason after a couple of days, my vpn tunnels back
to the office running the same snapshot on a full install wouldn't
stay up nor connect for long without continual rebooting of my home
firewall. Another curious thing was that the VPN to my data center
was working as I could ping, login, etc., but the associations did
not show up on the GUI nor via setkey -D on the console. It was most
peculiar...
So I decided last night to install snapshot 5/11 (built 5/13 it seems).
I tried the new upgrade menu option from the ssh login after
uploading the firmware to the home directory. The router continued
to run for the whole time routing, but the upgrade never seemed to
complete. After a while DNS stopped being resolved, and my ssh
connection was closed, and I couldn't connect to the web interface.
So I ran downstairs, hooked up a serial cable and found that there
was nothing to see on the console. Hitting 'ctrl-t' just said "not a
controlling terminal" and reported a load average of 2.00.
Since it had been over 20 minutes by this time, I pulled the plug and
rebooted the WRAP box. On reboot, I could see that it had the
absolute latest kernel, so the upgrade did apply at least some of
it. However, the console menu never showed up. Luckily I was able
to connect via ssh and restore the ttys_wrap file into /etc/ttys and
'kill -1 1' to restore that. To be safe, I used the rc.firmware
script to re-install the upgrade. It finished in a few seconds and
rebooted. This time, the ttys file was right, and everything seems
to be going at 100%. The VPN to the office is still up.
So I'm not sure if the 5/9 snapshot has issues that caused this
upgrade problem or the VPN problem, but the 5/11 snap seems pretty
stable so far on my embedded WRAP.
The 5/9 snapshot has been pretty stable on the full install at the
office, too.
I'm not upgrading the data center and remote offices until I'm 100%
safe with 1.2 release ;-) since I can't go fix them as easily.
