[SOLVED] L2TP error

PROBLEMCHYLD · 07-30-2016, 05:53 PM

I'm trying to install network-manager-l2tp-1.2.2, but I keeping getting an error message at the end of the script. Do anyone know how to fix it?

Code:

import-export.c: In function ‘export_ip4’:

There are more than one versions of Slackware. Which one are you using for this? Is it a full install?

PROBLEMCHYLD · 07-30-2016, 09:14 PM

Sorry for not being specific, but I'm using 14.2 with Generic Kernel and MLED. Seems like the script runs smoothly until it get to the end which spits out the error message I have posted. Thank you.

Richard Cranium · 07-30-2016, 09:28 PM

Where did you get the source that you are compiling and how did you proceed to build it?

PROBLEMCHYLD · 07-31-2016, 08:20 AM

I got it from here https://github.com/nm-l2tp/network-manager-l2tp and ran the script at the bottom. I tried both scripts and the results are the same.

Richard Cranium · 07-31-2016, 09:29 AM

Are you running Slackware64 14.2 or Slackware 14.2?

I'm running Slackware64 14.2. I downloaded a zip archive of the git link that you gave. I expanded that zip file, ran

Code:

./autogen.sh
./configure \
  --disable-static --prefix=/usr \
  --sysconfdir=/etc --libdir=/usr/lib64 \
  --localstatedir=/var \
  --with-pppd-plugin-dir=/usr/lib64/pppd/2.4.7
make

and everything appeared to build with no errors.

PROBLEMCHYLD · 07-31-2016, 10:36 AM

14.2 32bit

I changed lib64 to lib and I still get the error.

Richard Cranium · 07-31-2016, 11:15 AM

I'm not running 32 bit anywhere, so I won't be able to help. Good luck.

PROBLEMCHYLD · 09-03-2016, 09:31 AM

Does anyone know how to fix the error in the image? Everything compile with no problem, but installing the compiled contents gives me the errors.

gegechris99 · 09-03-2016, 11:58 AM

As root user, just type

Code:

make install

You don't need to use the sudo command

PROBLEMCHYLD · 09-03-2016, 01:52 PM

Thanks for the feedback, but still get the same errors. I have found something interesting on another forum. Maybe it can fix my problem. How do I approach it?

I saw this in network-manager-l2tp-1.2.2/README.md ...

Code:

# NetworkMananger-l2tp

NetworkManager-l2tp is a VPN plugin for NetworkManager 1.2 which provides support for L2TP and
L2TP/IPSec (i.e. L2TP over IPSec) connections.

For L2TP support, it uses xl2tpd ( https://www.xelerance.com/software/xl2tpd/ )

For IPSec support, it uses either of the following :
* Libreswan ( https://libreswan.org ) 
* strongSwan ( https://www.strongswan.org )

<<snip>>

Did you install xl2tpd and either ( Libreswan or strongSwan ) ?

The Networkmanager L2TP Plugin is intended for 64bit systems, at least the newer versions. This is why I switched to another client. I trying out the l2tp ipsec vpn daemon app. It seems like all L2TP apps are a pain in the azz on Slackware. Google doesn't help much and it is necessary for me to have it on my system.

Yes, Slackware DOES expect a bit more from the Operator.

But it also gives that Operator nearly complete control over their own System ( a feature that is just about extinct in all other OSen )

Both xl2tpd and strongswan are available as SlackBuilds so they should work 'out of the box' with 32-bit Slackware.

Neither xl2tpd nor strongswan have any REQUIRES= Packages.

So ... did you install the dependencies before you compiled the Network Manager PlugIn ?

####################################################

xl2tpd is an implementation of the Layer 2 Tunnelling Protocol (RFC 2661).
L2TP allows you to tunnel PPP over UDP. Some ISPs use L2TP to tunnel user
sessions from dial-in servers (modem banks, ADSL DSLAMs) to back-end PPP
servers. Another important application is Virtual Private Networks where
the IPsec protocol is used to secure the L2TP connection (L2TP/IPsec,
RFC 3193). The L2TP/IPsec protocol is mainly used by Windows and
Mac OS X clients. On Linux, xl2tpd can be used in combination with IPsec
implementations such as Openswan.
Example configuration files for such a setup are included in this RPM.

xl2tpd works by opening a pseudo-tty for communicating with pppd.
It runs completely in userspace but supports kernel mode L2TP. 

xl2tpd supports IPsec SA Reference tracking to enable overlapping internak
NAT'ed IP's by different clients (eg all clients connecting from their
linksys internal IP 192.168.1.101) as well as multiple clients behind
the same NAT router.

xl2tpd supports the pppol2tp kernel mode operations on 2.6.23 or higher,
or via a patch in contrib for 2.4.x kernels. Note that kernel mode and
IPsec SA Reference tracking do not yet work together.

I'm am not using network-manager-l2tp-1.2.2 plugin because it is intended for 64bit systems the reason for the errors on my system. I am using Slackware 32bit. So, to answer your questions, I did not install those packages because they wouldn't have done me any good. So I switch to another client and get the errors I posted. I am using

http://wiki.l2tpipsecvpn.tuxfamily.o...itle=Main_Page

I am not sure if I should change the first post because it seems to be causing confusion.
