Thread: Losing DNS on resume from standby


ubuntu 12.04 running on acer aspire 1 happy (pav70)

exclusively use netbook wifi - have ethernet port don't use it.

so, problem this:
1. use netbook in internet using wifi.
2. close lid , put netbook suspend-to-ram (standby/sleep).
3. open lid (after period of time) - netbook resumes s2r.
4. network manager connects wifi.
5. 10 seconds, you're go. after that, resolv.conf becomes empty.

@ point things annoying.

restarting network manager service re-connects wifi, drops dns settings per steps 4 & 5.

restarting whole networking service stack same.

manually issuing "sudo dhclient wlan0" seems sit there doing absolutely nothing. manually issuing "sudo ifconfig wlan0 down;sudo dhclient wlan0" brings step 4 & 5.

manually editing resolv.conf works... 10 seconds, , gets overwritten blank one.

resolution have found works reboot netbook... kinda negates whole point of putting suspend-to-ram in first place.

please note not want make resolv.conf immutable or other sledgehammer-to-crack-a-nut resolutions. find out causing problem can resolved.

advice , guidance appreciated.

grant.

Thread: Can not create raid array: mdadm: no raid-devices specified.

hello! i'm trying setup software raid on server, fail @ first step: code: root@sandnabba:/root# mdadm -c /dev/md0 -c512 -l5 /dev/sdc1 /dev/sdd1 /dev/sde1 mdadm: no raid-devices specified. what doing wrong!? are sure -c equivalent --create? also, think need space after -c , -l options, value shouldn't command, or should have = between. @ man pages mdadm , double check spelling.
