## How to user HP iLO2 Virtual Serial Console via SSH on Ubuntu
|
||
|
||
I’ve an old HP ProLiant DL360 G5 rack server with Ubuntu 16.04 at a remote location. Sometimes I’ve the need to remotely connect to it and look at the boot sequence.
|
||
|
||
iLO2 web interface has a Java applet to use the remote console but unfortunately with last versions of Firefox and Chrome it doesn’t work anymore.
|
||
|
||
So here we are:
|
||
|
||
### Configure GRUB to use VSP
|
||
|
||
To use and control GRUB via a virtual serial port we have to configure it:
|
||
|
||
1. In `/etc/default/grub` we need to change this lines:
|
||
|
||
```
|
||
GRUB_HIDDEN_TIMEOUT=15
|
||
GRUB_HIDDEN_TIMEOUT_QUIET=false
|
||
GRUB_TIMEOUT=15
|
||
GRUB_CMDLINE_LINUX="text console=tty0 console=ttyS1,115200n8"
|
||
GRUB_TERMINAL=console
|
||
```
|
||
|
||
That way the kernel messages are being redirected to tty0 and ttyS1
|
||
|
||
2. Create `/etc/init/ttyS1.conf` to start a getty on the vsp with:
|
||
|
||
```
|
||
# ttyS1 - getty
|
||
#
|
||
# This service maintains a getty on tty1 from the point the system is
|
||
# started until it is shut down again.
|
||
|
||
start on stopped rc RUNLEVEL=[2345] and (
|
||
not-container or
|
||
container CONTAINER=lxc or
|
||
container CONTAINER=lxc-libvirt)
|
||
|
||
stop on runlevel [!2345]
|
||
|
||
respawn
|
||
exec /sbin/getty -8 115200 ttyS1
|
||
```
|
||
|
||
### Connect to iLO2 via SSH
|
||
|
||
iLO2 support old key algorithms and chipers so we need to specify those:
|
||
|
||
```
|
||
ssh -o HostKeyAlgorithms=ssh-rsa,ssh-dss -o KexAlgorithms=diffie-hellman-group1-sha1 -o Ciphers=aes128-cbc,3des-cbc -o MACs=hmac-md5,hmac-sha1 ILO2_IP_ADDR
|
||
```
|
||
|
||
### Start the VSP
|
||
|
||
```
|
||
hpiLO-> VSP
|
||
|
||
Starting virtual serial port.
|
||
Press 'ESC (' to return to the CLI Session.
|
||
|
||
hpiLO-> Virtual Serial Port active: IO=0x03F8 INT=4
|
||
Ubuntu 16.04 ttyS0
|
||
|
