[nos-bbs] JNOS tun - fails to compile

[Jay Nugent]

Greetings fellopw NOSers,
    It has been a very long time since I have needed to compile JNOS, and I 
think I need a little help.

    I did an RSYNC to grab the latest source from Maiko's site.  The 
compile goes along fine until it encounters the first incidence of TUN.C 
at which point I get a few ERRORS and then it exits without creating an 
executable.

    Here is the output of that last lille bitof the compile:

--------------------------------------------------------------------

    The target machine is 64-bit running Debian Stretch/sid 
4.13.0-45-generic.


    If I understand this correctly, JNOS brings along the TUN code and it 
is not provided by the Linux distro?  I thought that it came with Linux 
but each machine I have tested CANNOT find the 'tun' device when I attempt 
to do an 'ifconfig tun0 192.168.100.100'.

    I don't find any Step-By-Step on Maiko's site that walks us through 
creating/installing a 'tun' device.


    Any help is welcome!
