One of the many things I'm working on in my copious amounts of spare time is
setting up the server that HP donated Linux Australia after I think
Said server has iLO, which facilitates remote power management and remote
console, both things I want to have working on this server before it goes
Jon's been madly poking holes in his firewall for me so I could access the
iLO stuff. I'm already liking it better than Dell's BMC, because it has
things like SSH, although the whole thing hasn't been without some
I fiddled around via the web interface and added an account for myself and
an SSH key. Then I tried to SSH in, and promptly got stuff like
buffer_get_ret: trying to get more bytes 4 than in buffer 0
buffer_get_int: buffer error
straight after what looked like a successful connection, and then the SSH
connection got terminated.
I did a pile of Google searching, and found people had to disable
environment variable sending, and agent forwarding to get this to stop
happening. Interestingly, I can't find a way to disable SendEnv on
a per-host basis with OpenSSH, if it's been set in
/etc/ssh/ssh_config, which is kind of annoying.
So after solving the problem of gaining SSH access to the iLO, I then
battled with the remote console. The host already had a throwaway
Linux installation on it, but the remote console kept freaking out about the
console being in graphics mode. I figured this was because it was using a
frame-buffer. No problem, I just needed to boot with vga=normal.
Problem was, GRUB was configured with hiddenmenu so I had 3 seconds
to hit Escape before it charged off and booted up. Not that big a deal you'd
think, except to get out of the remote console and back to the iLO prompt,
you have to hit Escape (, so the iLO eats Escape keys for
After having a bit of debate with some mainly Red Hat-oriented sysadmins on
#sage-au, it turned out that RHEL has a patch so that GRUB accepts any key,
not just Escape to present the menu. That was no use to me, as the box
wasn't running RHEL. And all I was asking for was if anyone had any iLO
experience, no whether or not "any key" was the equivalent of Escape.
It turned out that I needed to press Escape twice in that initial 3
seconds, with probably sufficient pause between the two presses for it to
register properly, in order for an Escape character to be sent to GRUB.
