kppp root/user problem

[the bassinvader]

hello everybody!

I have a dial up connection set up with kppp in the root account which works fine and i want to use the same connection for other users as well. I've set up the connection in other accounts however when i go to connect to the internet or query the modem kppp says that its unable to open the modem !?!

As well as this when i first click on kppp on the desktop it tells me;

you dont have sufficient permission to run /usr/sbin/pppd

please make sure that kppp is owned by root and has the
SUID bit set

what does this mean and how is it solved?



i'm using Suse 10.0 with an external serial modem

[devils casper]

execute this

chmod +s /usr/bin/rfcomm

well yes and no

i executed devils caspers code but it didnt do anything on its own (sorry)

So i started to look through the archives for advice (i know ...what i should
have done in the first place) and took all the advice that you got yankeeco
and tried it out. This is what i did in order:

Executed chmod +s /usr/bin/rfcomm
then i lost my rag and deleted all the modem info in kppp and re wrote it
( this gave me the "unable to create lock file" message)
then i executed chmod u+s /usr/bin/rfcomm
and finally i checked the UUCP box for my user account

the result of all this was that kppp can now detect the modem with no problems
however i still get this message when i first start up kppp:

you dont have sufficient permission to run
/usr/sbin/pppd
please make sure that kppp is owned by root and has the SUID
bit set.

Hope this is of help to you yankeeco but i cant remember what modem you're
using. Just for the record i've got an external serial by Zoom.

Unfortunatly this isnt the end of the problem. After dialing i get
a message like this:

pppd daemon died unexpectadly
Exit status 3
see `man pppd´ for an explanation of the error codes
or take a look at the kppp FAQ on http://developer.kde.
org/~kppp/index.html

the ppp log says this:
cannot open any of these log files
/var/log/syslog.ppp
/var/log/syslog
/var/log/messages

if you've got any ideas devils casper send 'em my way please.

Thanx

Hi guys .

I've been searchin through the net for a solution to my problem, and maybe i've found something!!! I'm not sure though but it seems to have worked on older distro's that have had exactly the same problem....well thats what i've been reading, but being a linux noob and not knowing my way around yet i want someone to check exactly what i'm doing so i dont break anything!!

Here's the instructions i've found:

I have the solution

Just solved this two nights ago. Here we go.
1) open etc/ppp/peers/kppp-options and remove the # in front
of noauth if it is there.
2) open etc/ppp/pap-secrets and make sure your isp username
and password are there, again with no # in front of the line.
3) open etc/ppp/peers/provider and first make sure the correct
modem is listed, mine is on com port 2 so my line reads
/dev/ttyS1. Then this is the biggie because this line was very
wrong on mine. The chat script line should read :
connect "/usr/sbin/chat -v -f /etc/ppp/peers/provider"
That should do it.
By the way when putting settings in kppp (click configure button)
i used PAP and CR/LF and CRTSCTS and 115200 and /dev/ttyS1(which in
my case is com port 2).


will it set my hair on fire or what?

Saw what you have there and will have to try it.

At this point I'm almost as familiar with using Linux in the Terminal mode as I was with MS/DOS so finding my way around in the "etc" directory is no longer a problem - just time consuming.

The only reason I'm interested in this end of it is that I want to be able to fully exploit the abilities of "Contact" which I've found to be an excellent piece of PIM software.

Oh, you asked what modem am I using . . .

I'm using a Dell Inspiron 5100 laptop and the built in modem. When using Linux (which I do now far more often that the old MS XP OS)
the built-in modem works just fine - only when I'm in ROOT but not at all when in what I call the primary user directory (PUD?)

I'll keep you posted - and thanks for the interest!

This is just an update for anybody who has the same problem that I had.

Here's the solution that worked on my system:


First in a konsole......su to root and type; chmod u+s /usr/bin/rfcomm


The user will need read, write and execute permission in:
kppp and /etc/resolv.conf

And the user set uid box should be checked in;
opt/kde3/bin/kppp

After this I got accounts other than root on the internet and my headaches stopped!

I don't know about any security implications so if theres anything terrible please feel free to tell me


Later
