Re: wvdial permissions modem device
matt zagrabelny, 2003-Mar-07 09:16 -0600:
i am currently stopping wvdial with:
killall wvdial
sometimes the permissions to /dev/modem (/dev/ttyS0)
which are usually root dialout -rw-rw
do not get reset to this.
i know that when pppd is running that it removes
group rw to the device, effectively making the permissions
600, and then when pppd is shutdown properly it restores
them to 660. so then it appears that pppd is not shuting
down properly.
1) does anyone else experience this problem?
I have not. I run wvdial from a terminal and when I'm done I Ctrl-C
in that terminal. The Ctrl-C always shuts down pppd properly.
2) do you know why sometimes wvdial can properly kill pppd
and other times it cant?
Nope.
3) what solutions have people used for this problem?
I haven't needed one, but you could right a script that will kill both
wvdial and find the PID of pppd and kill it too, if it exists.
Something simple run from root, or preferrably sudo:
bof
#!/bin/sh
echo Stopping wvdial...
killall wvdial
echo Checking pppd...
PPPD_PID=`ps axww | grep pppd | awk '{print $1}'`
if [ $PPPD_PID != ]; then
kill -9 $PPPD_PID
echo pppd process killed
else
echo pppd already dead
fi
eof
Bear in mind, this bitty script is quick and dirty and needs testing.

wvdial permissions
I have been using wvdial without difficulty for weeks. Upon use this evening, I am getting permission denied cannot open /dev/ttyS2. Any Idea on why this has changed? No one has made any (known)changes. What should /dev/ttyS2 permissions be on a standalone desktop system? ls -l:crw-r-1 root dialout 4, 66... wvdial works fine as root (I understand I should not). Thanks -Wade Wade Barocsi [EMAIL PROTECTED]

A known bug in wvdial. The port should be group writeable. Just change it back. wvdial works fine as root (I understand I should not). There's no special reason not to run wvdial as root. -- John Hasler [EMAIL PROTECTED] Dancing Horse Hill Elmwood, Wisconsin
Wvdial permissions
I always end up doing horrible, insecure hacks in order to access the wvdial stuff, and since I am now using wvdial's home distribution, I'd like to do it properly. Here's the current error: cmayes:~$ wvdial -- Can't read config file: Permission denied Here's the config file's permissions: -rw-r- 1 root dialout 186 Mar 29 21:54 /etc/wvdial.conf This means that the dialout group can read it, right? So, I did this to the dialout line of /etc/group: dialout:x:20:cmayes: Is that the right way to do it? It still doesn't work, so aparrently not ;-) As always, your help is very much appreciated.
