compiling vlock for 9.1

vrillusions · 11-25-2003, 02:36 PM

I'm trying to get vlock to work. I use that laptop at work alot... at an ISP... around a bunch of people that know linux. So needless to say just using the lock in KDE isn't going to stop them from going to the shell connections. In mandrake, it had vlock already compiled and I just had to install the package and I was good to go. Here, I think the shadow passwords is what's messing me up. I found a precompiled version, but for an old distro at http://homepages.paradise.net.nz/~ca.../packages.html I tried to run that and it said it couldn't do it for mine, probably because it was trying to read the regular password and not the shadow file. So I tried to compile it on my own. Found the distro at http://linux.maruhn.com/sec/vlock.html (went for one of the .tar.gz files) and then tried to compile it and it couldn't find the crypt() function, again because I am using shadow files instead. I also had to disable PAM options in it. What is PAM used for? Has anyone ever gotten it compiled and can just link to it or say how you did it? thanks.

From my understanding PAM still isn't part
of Slackware, PAM is the "pluggable authentication
module" that would allow you to for instance authen-
ticate against a user-database in PostgreSQL, or
OpenLDAP ...

I can't say anything about 9.1, but it compiles
fine in 8.1, with no modifications (and I use the
shadow-password suite, too) ...

Cheers,
Tink

ok, here's the entire session from me trying to compile it (sorry for it being a little long). also, that time I edited the make file, I removed the PAM references. I can post the makefile here too if that would help.

Code:

root@oriana /tmp$ wget --passive-ftp ftp://ftp.nnov.net/pub/software/linu...ock-1.3.tar.gz
--17:33:17--  ftp://ftp.nnov.net/pub/software/linu...ock-1.3.tar.gz
           => `vlock-1.3.tar.gz'
