Hay all. This is a weird one and I'd love to know the answer... Server is on 24/7. Server is set to connect to the internet (dialup to Demon) every 2 hours. When it connects it sends me email with IP address. Yes I do know Demon SDU has fixed IP... Anyway, I never get the email after 6pm and before 8am. I think nothing of it. Yesterday I installed (as you know) cacti and mrtg. So I look at the graphs this morning and from 17:50 to 08:24 they all flat line. Zilch, nothing. I check syslog and there isn't a single entry between these two times. So after general paranoia sets in, tightening of firewall etc etc I have another think and still can't come up with anything. The other interesting thing (and why I don't think it's been hacked) is that the uptime is wrong, but the date is right. I rebooted the machine yesterday morning, yet this morning it was showing an uptime of 9 hours. I know for a fact it hasn't been turned off. My hunch is that the network card (3Com 905) is somehow putting it to sleep. This is based on the idea that the one remaining other machine on the network would have been turned off at about 17:50 last night and would have been turned on at about 08:24 this morning. Between these times, other machines would have had power and other machines all have 3Com Cards which are still 'on' even though the machine is off (soft-off) - the switch shows the nics are actually still on. Is this possible? Is this at all likely? Is there anyway of stopping this? I've not set anything up specifically to do this and I'd love to stop it! Answers on a postcard please!
