VPN attempt (via tunnelv) -- how do we get ethertap going?
[or, is there a better way than tunnelv to do the VPN hookup?]
the tunnelv README says only
>To set up Tunnel Vision on a Linux machine, you need:
>
>- Linux 2.1.112 or higher with the "ethertap" and "netlink" devices
> configured. Sorry, we know it's unstable, but we needed to use
> the new features.
>
> You need to load one ethertap kernel module for each tunnel you
> want to open at a time. Many people will just use one tunnel, so
> you only need one ethertap.
>
>- The SSLeay library. The only one we've tested is version 0.9.0b,
> so if you have problems, try switching to that version. SSLeay
> does the actual low-level encryption for TV. Look at
> ftp.replay.com to see if you can find SSLeay.
>
>- libc6, probably. We haven't tested it with anything else.
based on debian.org browsings, i know where to get libc6 and that
ssleay has been replaced by openssl. but my web searching for
ethertap has turned up very little.
Q: how do i enable ETHERTAP if it's a software-only thing? i've got
/usr/src/kernel-headers-2.2.17/include/config/ethertap.h
/usr/src/kernel-headers-2.2.17/include/config/ethertap
/usr/src/kernel-headers-2.2.17/include/config/ethertap/module.h
/lib/modules/2.2.17/net/ethertap.o
but have not clue what to do with them.
ifconfig? /etc/network/interfaces?
Q: same for NETLINK: what is it, how do i turn the hockeypuck on?
Q: modconf shows 'ipip' as an installable module. is it needed?
is it useful?
RTFM pointers hereby solicited. which FM?
