User tux and internet

Maybe already solved the issue of internet using from the user tux?

I can connect to internet via my modem and wvdial only as root. It is easy. I use script:

[c]

#!/bin/sh

subox xterm -hold -e "wvdial -C /home/tux/mts.wvdial.conf"

[/c]

Double click script, enter, done.

I can browse internet in midori as root:

Menu → Run → subox midori

And I can't use Mercurial (hg) as tux.

[c]

tux@slitaz:~/tests$ hg clone http://hg.slitaz.org/spk

abort: error: Name or service not known

tux@slitaz:~/tests$ su

Password:

root@slitaz:/home/tux/tests# hg clone http://hg.slitaz.org/spk

destination directory: spk

added 13 changesets with 26 changes to 9 files

updating to branch default

[/c]

I commanded:

[c]

# addgroup tux dialout

# addgroup tux wheel

[/c]

log out and log in, but nothing has changed.

[c]

tux@slitaz:~$ ls -l /dev/ttyACM*

crw-rw----    1 root     dialout   166,   1 May 14 22:27 /dev/ttyACM1

crw-rw----    1 root     dialout   166,   2 May 14 22:27 /dev/ttyACM2

crw-rw----    1 root     dialout   166,   3 May 14 22:27 /dev/ttyACM3

[/c]

Re: User tux and internet

It's because pppd keeps changing resolv.conf to 600 (read/write for root only).

The quick fix for it is to modify /etc/ppp/ip-up and /etc/ppp/ip-down to correct this automatically:

/etc/ppp/ip-up:

[c]#!/bin/sh
if [ -n "$USEPEERDNS" -a -f /etc/ppp/resolv.conf ]; then
    rm -f /etc/ppp/resolv.prev
    if [ -f /etc/resolv.conf ]; then
        cp /etc/resolv.conf /etc/ppp/resolv.prev
        grep domain /etc/ppp/resolv.prev > /etc/resolv.conf
        grep search /etc/ppp/resolv.prev >> /etc/resolv.conf
        cat /etc/ppp/resolv.conf >> /etc/resolv.conf
        chmod 644 /etc/resolv.conf
    else
        cp /etc/ppp/resolv.conf /etc
        chmod 644 /etc/resolv.conf
    fi
fi[/c]
/etc/ppp/ip-down:

[c]#!/bin/sh
if [ -n "$USEPEERDNS" -a -f /etc/ppp/resolv.conf ]; then
    if [ -f /etc/ppp/resolv.prev ]; then
        cp -f /etc/ppp/resolv.prev /etc/resolv.conf
        chmod 644 /etc/resolv.conf
    else
        rm -f /etc/resolv.conf
    fi
fi[/c]

Re: User tux and internet

Thank You, Brenton!

You point me to right direction. I just changed permissions for /etc/resolv.conf and started wvdial from tux user.

I not changed scripts. Now, when I run wvdial (and pppd):

[c]

tux@slitaz:~$ ls -l /etc/ppp/resolv.conf

-rw-r--r--    1 root     root            48 May 15 14:56 /etc/ppp/resolv.conf

[/c]

When scripts ip-up & ip-down copy /etc/ppp/resolv.conf to /etc/resolv.conf then permissions may back to 600?

Re: User tux and internet

Yes, but it originally copied the /etc/ppp/resolv.conf from /etc/resolv.conf - this is also why connecting for the first time on a fresh install always works and the second time gives you the error. Replacing the scripts is the fastest and easiest way to fix it without having to change /etc/resolv.conf permission.
