[SOLVED] idle headless arch, disables wired lan

scarletxfi · 2010-06-18 03:16:53

Hey,

I've recently installed a headless arch linux thats works near-perfectly.
Although, once its booted I have about 5 minutes to ssh to it without the network disconnecting
I say disconnecting, because I can't ping it, and as it boot headless i can't connect a monitor to it.
I've got the same hardware configuration on another arch linux, with a gui - and it runs fine.

I've set the following in both ssh_config, sshd_config (server and client):
TCPKeeplAlive yes
ServerAliveInterval 5

I dont know if this matters but the computer only has power and network connected to it.

How do I keep the network alive?

if needed i will provide more info.

since even ping stops after your disconnection, it means that the problem can either be a firewall setting, or a faulty ethernet card or even a bad ethernet wire. it could also be dhcpcd itself loosing the leases, try setting your system to a static ip.

scarletxfi · 2010-06-23 06:08:04

changed cables, same thing.

I set static IP and that does'nt help either.

fixed with adding "acpi=off noacpi" to GRUB options

thanks for the help.

h2vnteam · 2010-07-18 10:12:57

Wow, that does the trick scarletxfi, I had the same thing, checked the cable and the NIC several times, but still the same, now it's steady.

Thanks for your time experimenting.

experiment with apm. when I have these in the menu.lst, and I issue "shutdown -h now" the computer halts at "powering off".
to fix that add the options:

apm=power-off acpi=off

to menu.lst (ie apm=power-off instead of noacpi )

h2vnteam · 2010-07-19 02:32:25

I tried your fix last night, but when I left it with poweroff command, the machine hung and refused to shut. Was struggling, but luckily you've just solved the problem so quickly.

All those options scarletxfi has mentioned above, should be landed before "ro" in the menu.lst

Anyway, my student will stop moaning that he cann't shutdown his machine.

Thanks for all the hard work!
