Hi, I hope I have not missed something obvious, but I am quite new to Zeroshell, the machine has been installed for about 2 weeks, it has three network cards and provides separation between two users of an internet connection.
Today I suddenly found the machine unresponsive and reporting high load averages (>20 !!) When I checked logs, I found multiple DHCP INFORM packets coming from one or two machines on one of the networks, by multiple I mean dozens per second.
Looking round the internet for a solution I came across a site indicating that there was a possible problem with XP and WIN7 machines repeatedly asking for wpad requests [http://www.linuxquestions.org/questions/linux-server-73/dhcpinform-clogging-my-system-log-770904/]
The solution involved putting a new definition into the DHCP configuration along the lines of:
option wpad code 252 = text;
and then using this with an entry:
option wpad “n 00”;
to suppress the continuous requests.When I tried putting this definition into the advanced dhcp options in zeroshell I kept getting the error “option definitions may not be scoped.”
This is because zeroshell places the definition in the scope of the ip subnet you are editing. Is there a workaround for this?
In the event, I found my problem elsewhere, some idiot had plugged two switches together with two cables!! 😛 [/url]
