xl2tpd compilation problem
« on: December 24, 2022, 03:16:57 PM »
I need to use xl2tpd on tinycore, I can't find it in the software repository,
so I have to try to compile it. Here are my steps:


 tce-load -iw compiletc.tcz
 tce-load -iw libpcap-dev.tcz

wget https://github.com/xelerance/xl2tpd/archive/refs/tags/v1.3.18.tar.gz

tar -xvf v1.3.18.tar.gz

cd xl2tpd-1.3.18

make

Finished smoothly, no error, what should I do next to get xl2tpd running thank you。

You would package it as a tcz extension, then run it according to its instructions. The book (link on the front page) contains an example of making a tcz.
The only barriers that can stop you are the ones you create yourself.

Thanks for curaga and gadget42's reply. I have found a lot of posts,
 but unfortunately I have not found complete examples,
which makes my following work in trouble.
 Can anyone provide a complete tutorial or link?
Search keywords are good too, thanks.
Maybe I'm not qualified for this job?
 But I need the xl2tpd client and hope someone can help me,
 I see a lot of discussion on the forum about l2tp,
it seems to have no results.

Oh, the forum is finally ready to reply!

It still doesn't seem to be Posting, and sending the command line is an error.

Now that xl2tpd is working, I intended to reply from the command line in order to clarify the process, but unfortunately this will cause an error.
Text description:

After compiling, extract the following files to the corresponding directory:

/xl2tpd/usr/local/bin/pfc
/xl2tpd/usr/local/sbin/xl2tpd
/xl2tpd/usr/local/sbin/xl2tpd-control
/xl2tpd/etc/xl2tpd/xl2tpd.conf
/xl2tpd/etc/xl2tpd/options.xl2tpd

mksquashfs xl2tpd/ xl2tpd.tcz

tce-load -iw pppd.tcz
tce-load -i xl2tpd.tcz

The basic work is done.

There is one problem to deal with: pppd defaults to /usr/local/sbin and xl2tpd to usr/sbin

ln -s /tmp/tcloop/pppd/usr/local/sbin/chat /usr/sbin/chat
ln -s /tmp/tcloop/pppd/usr/local/sbin/pppd /usr/sbin/pppd
ln -s /tmp/tcloop/pppd/usr/local/sbin/pppdump /usr/sbin/pppdump
ln -s /tmp/tcloop/pppd/usr/local/sbin/pppstats /usr/sbin/pppstats
ln -s /tmp/tcloop/pppd/usr/local/sbin/pppoe-discovery /usr/sbin/pppoe-discovery
source  /etc/profile
sudo xl2tpd -D
sudo xl2tpd-control connect-lac vpn
Good, it worked!

One detail is missing:
sudo mkdir /var/run/xl2tpd
It is used to store the control file l2tp-control
xl2tpd generates this file automatically

      After about a week of hard work, I finally got it ready to share with you.
I know I'm a layman when it comes to packaging modules, so if anyone has
a spare moment,And familiar with packing work, can do a good job to the
warehouse. Convenient for more people to share.Thanks!

Hi qingquan
There is one problem to deal with: pppd defaults to /usr/local/sbin and xl2tpd to usr/sbin ...
That's caused by line  65  in  l2tp.h:
https://github.com/xelerance/xl2tpd/blob/69b241082d02f6b4c28d6aef6c97c5738e834ff1/l2tp.h#L65

You can either change it in  l2tp.h  or add the following to your  CFLAGS=  setting:
Code: [Select]
-DPPPD=\"/usr/local/bin/pppd\"
