dnsmasq error

Message

I had dnsmasq running on my server for a long time, but now it won start from init.d. I get the following error message:

Code: Select all

 $ /etc/init.d/dnsmasq start
 * Starting dnsmasq ...

dnsmasq: setting capabilities failed: Operation not permitted                                         [ !! ]

Same error when I try to run dnsmasq straight from the command line, however, if I run it in debug mode, it works great:

Code: Select all

 $ dnsmasq -d
dnsmasq: started, version 2.45 cachesize 150
dnsmasq: compile time options: IPv6 GNU-getopt no-ISC-leasefile no-DBus I18N no-TFTP
dnsmasq: DHCP, IP range 192.168.0.50 -- 192.168.0.150, lease time 12h
dnsmasq: reading /etc/resolv.conf
dnsmasq: using nameserver 68.87.73.242#53
dnsmasq: using nameserver 68.87.71.226#53
dnsmasq: read /etc/hosts - 5 addresses

Please help!

Thanks! -Ross

looks like you're not starting it as root? you need to do that for it to work properly. It would normally switch to user nobody once it's done with it's startup - that bit is probably failing coz you're not root.

It works with -d because that disables the switch user bit

Good idea, but I'm definitely logged in as root when I'm trying all this

. Any other idea?

According to your prompt, you're not.

OK, if you want to see the full cut-n-paste, here it is:

Code: Select all

root@porcupine ~ $ dnsmasq

dnsmasq: setting capabilities failed: Operation not permitted
root@porcupine ~ $ dnsmasq -d
dnsmasq: started, version 2.45 cachesize 150
dnsmasq: compile time options: IPv6 GNU-getopt no-ISC-leasefile no-DBus I18N no-TFTP
dnsmasq: DHCP, IP range 192.168.0.50 -- 192.168.0.150, lease time 12h
dnsmasq: reading /etc/resolv.conf
dnsmasq: using nameserver 68.87.73.242#53
dnsmasq: using nameserver 68.87.71.226#53
dnsmasq: read /etc/hosts - 5 addresses

For now, I'm running 'dnsmasq -d &' just so that I can work, but I really want to fix this!

Didi you emerged/unmerged sys-libs/libcap-2.11 recently (POSIX capabilities) ? Or maybe some other libs, therefore I'd advice a "revdep -- --ask".

That's possible -- I'll try it when I get home tonight. Thanks -Ross

Alas, revdep-rebuild turned up nothing

. I did not have sys-libs/libcap installed, so I tried it, but that didn't help either; exact same response

.

Any other ideas? Please??
Thanks -Ross
