[ale] tun on Ubuntu

[PairOfTwins]

Bjorn & Jim:

Ha!  tuncfg is 32-bit.  Guess "make" didn't really make this utility?  
Looking for a way to have remote desktop when the client doesn't have 
access to the router (small rental office in big building).


tom at dare:/sbin$ sudo file tuncfg
tuncfg: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for 
GNU/Linux 2.4.1, dynamically linked (uses shared libs), stripped
tom at dare:/sbin$ sudo ldd tuncfg
        not a dynamic executable

Thanks,
Tom
