Re: Network Manager overwriting resolv.conf
That didn't work for me. But there's another workaround, if you're using the ext2 filesystem, use the chattr command to make /etc/resolv.conf immutable, so no process can change it
Code:

$ sudo chattr +i /etc/resolv.conf

now even root can't change the file until that attribute is removed.

Re: Network Manager overwriting resolv.conf
Found a workaround. I opened /etc/dhcp3/dhclient.conf

Uncommented the line that starts with "#prepend domain-name-servers" and added my DNS server to it. Then did: sudo /etc/init.d/dhcdbd restart

1) at vyzkousi ping 8.8.8.8 - at je jistota ze je chyba jenom v prideleni DNS serveru
2) networking restart
3) nastavit /etc/resolv.conf na read-only }nejjednodussi reseni...

kamoska ma na notasu s ubuntu problem s pripojenim k netu, bohuzel je daleko, resime to akorat po telefonu.

je pripojena pres adsl modem normalne na ethernet, ping na modem v poho, do jeho nastaveni se dostane taky, modem je k netu pripojenej korektne.

na net se ale nedostane, resp. dostane az po /etc/init.d/networking restart

/etc/resolv.conf je prazdnej, resp. obsahuje akorat zakomentovanej text "generated by NetworkManager"

HONCKA: jeste doplnim ze krome firewallu muze pripojeni blokovat i spatne nastaveny soubor /etc/hosts.allow resp. /etc/hosts.deny

u me je v /etc/hosts.allow explicitne uvedeno:

sshd: ALL

coz povoluje pristup odevsad

Hi!
I have Synology DS-110j,and Eaton Ellipse1000 connected via USB.

I've got following problem with USB, unfortunatelly I can't find the config.out as I have installed apcupsd via ipkg.

APCUPSD version 3.14.8

UPS - EATON Ellipse 1000 - USB cable

To use with USB port I did

CODE:
ipkg install apcupsd
cd /opt/etc/apcupsd
sed -i 's/UPSCABLE smart/UPSCABLE usb/g' /opt/etc/apcupsd/apcupsd.conf
sed -i 's/UPSTYPE apcsmart/UPSTYPE usb/g' /opt/etc/apcupsd/apcupsd.conf
sed -i 's/\/dev\/ttyS0//g' /opt/etc/apcupsd/apcupsd.conf
mkdir /opt/var/lock
chmod 777 /opt/var/lock
touch /opt/var/log/apcupsd.events
touch /opt/var/log/apcupsd.status

CODE:
cat /proc/bus/usb/devices

CODE:
dmesg | grep hiddev

usbcore: registered new interface driver hiddev
hiddev104: USB HID v1.11 Device [OMRON USB UPS] on usb-ehci_marvell.70059-1.1

All seems good!
When i try it:

please see http://www.apcupsd.com/support.html.
apctest error termination completed

In APC's manual
Problem
USB driver linux-usb.c fails to compile, reporting errors about HID_MAX_USAGES undefined. This is due to a defect in the linux kernel hiddev.h header file on 2.6.5 and higher kernels.
Workaround
Upgrade to apcupsd-3.10.14 or higher. These versions contain a workaround for the defect.
BUT i USE apcupsd 3.14.8 :cry:
Any ideas??
