First of all sorry for the lengthy email. I am not shure about the "dos and
don'ts" for this list. Should I send these details only tothat paerson who
asked for?
The box is connceted to our company 10 MBit etherent which should not harm
a lot or?
It would be great if you could have "a look", but don't know what you
exaclty mean.
If you meant logging in to the system, that would be fine.
I am behind a NAT router, so would it be possible to send you an xterm to a
given IP address?
The box is a HP ProLiant ML110:
Intel 879P core logic chipset consisting of:
82879P north bridge
ICH-S south bridge
Phoenix® BIOS v4.06 chipset
SMSC® LPC47M192 Super I/O chipset
Onboard Broadcom® 5705 10/100/1000 Mbps Gigabit Ethernet controller
ATI® Rage XL chipset with 8 MB SDRAM of video memory
Four DIMM slots with support for:
DDR 400 unbuffered ECC DIMMs in 256 MB, 512 MB, or 1 GB configuration
Up to 2 DIMMs per-channel, single-sided and/or double-sided
Byte masking on writes through data masking
Single-bit Error Correcting Code (or Error Checking and Correcting) on
the system
memory interface
Five PCI bus slots with two separate bus channels
Two 32-bit/33 MHz 5V PCI bus slots
Three 64-bit/66 MHz 3.3V PCI-X bus slots
After booting dmesg shows me:
