Where is tcl / tk ?
 

I tried to install tkpppoe which required tcl / tk.
I installed tcl but could not find tk .
How to get it ?

The tk package is in the slackware/tcl directory of your installation media and on the Slackware mirrors.

I should be installed if you made a full install, which is recommended, if you use Slackware.

But I can't be sure I gave you a relevant information as you do not indicate for which distribution and version you miss it :scratch:

I have installed the full dvd version of slackware 12.2 yet tcl / tk is not there. Downloaded the tar.gz packages and installed it. I had to login as root and invoke tkpppoe yet I could not connect to internet.

Invoking tkppoe from CLI gives this o/p.

root@darkstar:/home/sridhar# tkpppoe
No protocol specified
Application initialization failed: couldn't connect to display ":0.0"
Error in startup script: invalid command name "tk"
while executing
"tk appname TkPPPoE"
(file "/usr/bin/tkpppoe" line 40

If you're trying to run it from a terminal while you're running an X session as a regular user, you may get this.

The command for tcl interpreter is "tclsh" and for Tk applications it is "wish". Do you have these in your path?

It should be there. May be a problem with your installation media ?

I suggest you try this, as root (I suppose you mounted your DVD as /media/dvd; change that to fit your DVD's mount point):This should install or reinstall all tcl/tk related packages.

FYI (I keep a local mirror of the distribution up to date with rsync):If you do not have one of these packages, you can get it using the Slackware Package Browser.

When I login as root I could invoke tkpppoe and connec to internet. But I could not do so as ordinary user. I have marked "Allow non=root users" option in tkpppoe.
As ordinary user I get the tkpppoe running but it doesn't connect to net.
Checked file permissions for pppoe-start / stop and resolv.conf and they are ok.

root@darkstar:/home/sridhar# ls -l /etc/ppp/resolv.conf
-rwxr-xr-x 1 root root 54 2009-02-18 08:15 /etc/ppp/resolv.conf

root@darkstar:/home/sridhar# ls -l /usr/sbin/pppoe-start
-rwxr-xr-x 1 root root 5599 2009-02-17 22:11 /usr/sbin/pppoe-start

root@darkstar:/home/sridhar# ls -l /usr/sbin/pppoe-stop
-rwxr-xr-x 1 root root 2323 2009-02-17 22:11 /usr/sbin/pppoe-stop

root@darkstar:/home/sridhar# ls -l /usr/bin/tkpppoe
-rwxr-xr-x 1 root root 108493 2009-02-17 21:48 /usr/bin/tkpppoe

Then you obviously have Tcl/Tk. In the first example that you gave, you're trying to run tkpppoe as root. Please give the terminal output you get as an ordinary user.

A workaround: Try "ssh -Y root@127.0.0.1" and run your script.

Whe I ran tkpppoe as normal user I get the dialog box of tkppoe but when I press the start button nothing happens and I could not connect to net.

This problem is with slackware only. I can run this s/w successfully in other distros (Arch , PCLOS, Zenwalk etc. )

Are there any log files? I think we need more debugging info. But it's likely to be some sort of permissions problem.

I agree. I tried changing to a+x for /etc/ppp , pap-secrets, resolv.conf etc but still the problem persists.

I don't have the log file .

chmod a+x only make theses files executable by all. That is not the point.

Check who is authorized to read/write on theses files instead.
