In the following notes, "iLO" refers to iLO and iLO 2 unless otherwise noted.
OpenSSH problems with iLO ssh server
OpenSSH on my Ubuntu 7.10 system is incompatible with the ssh server on an iLO 1.91 system.
$ ssh -V OpenSSH_4.6p1 Debian-5build1, OpenSSL 0.9.8e 23 Feb 2007
$ echo "QUIT" | nc iLO 22
$ ssh admin@iLO admin@iLO's password: dispatch_protocol_error: type 100 seq 9 dispatch_protocol_error: type 100 seq 10 buffer_get_ret: trying to get more bytes 4 than in buffer 0 buffer_get_int: buffer error
As a workaround, PuTTY 0.60-1's ssh client works with the iLO ssh server.
To upgrade iLO firmware through the iLO HTTPS interface, download the Online ROM Flash Component for Windows, Extract the files, and Send firmware image of the appropriate firmware file (e.g., ilo191.bin). Note that wine for UNIX systems works with the self-extracting .exe file.
