Configure error libpam required but missing

Issue

In Linux, download the openvpn source and configure, and run the commands blew.

$ wget https://swupdate.openvpn.org/community/releases/openvpn-2.4.9.tar.gz
$ tar xf openvpn-2.4.9.tar.gz
$ cd openvpn-2.4.9
$ ./configure

But I get the error message saying:

checking for LZ4... no
checking lz4.h usability... no
checking lz4.h presence... no
checking for lz4.h... no
		usable LZ4 library or header not found, using version in src/compat/compat-lz4.*

checking whether the compiler acceppts -Wno-unused-function... yes
checking whether the compiler acceppts -Wno-unused-parameter... yes
checking whether the compiler acceppts -Wall... yes
configure: error: libpam required but missing

Solution

It needs to install pam development package.

• RHEL/CentOS

Go to https://pkgs.org/search/?q=pam-devel and download pam-devel, or run with yum.

sudo yum install pam-devel

• Ubuntu/Debian

Go to https://pkgs.org/search/?q=libpam0g-dev and download libpam0g-dev, or run with apt-get。

sudo apt-get install libpam0g-dev

hi everyone,

I am trying to update my OpenVPN and OpenSSL.
In order to Update and Configure and Make Install OpenVPN to openvpn-2.4.4, I need to update my openssl to the latest openssl-1.0.2n

$ cd~
$ wget https://openvpn.net/index.php/download/openvpn-2.4.4.tar.gz
$ sudo tar -zvxf openvpn--2.4.4.tar.gz
$ cd openvpn-2.4.4
$ sudo ./configure
$ sudo make
$ sudo make install

But when I reach ./configure above, I run into an issue with openssl as I have mentioned earlier:

checking tap-windows.h presence... no
checking for tap-windows.h... no
checking whether TUNSETPERSIST is declared... yes
checking for setcon in -lselinux... no
checking for pam_start in -lpam... no
checking for PKCS11_HELPER... no
checking for OPENSSL... no
checking for SSL_CTX_new... no
configure: error: openssl check failed

So I am attempting the following commands to update to the latest openssl :

$ cd /usr/src
$ wget https://www.openssl.org/source/openssl-1.0.1j.tar.gz -O openssl-1.0.1j.tar.gz
$ tar -zxf openssl-1.0.1j.tar.gz
$ cd openssl-1.0.1j
$ ./config
$ make
$ make test
$ make install
$ mv /usr/bin/openssl /root/
$ ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
$ openssl version

However, when I get to make test , I run into an error.
I have copy pasted my terminal output here because the output is HUGE : https://pastebin.com/sZVXiZaE

Does anyone have any idea how to move past this bug to continue and finish my openssl install?
Your help is highly appreciated.

The company I have been working for for a couple of months has an OpenVPN server running. Recently I wanted to install the client software on my Windows 7 desktop and my Linux laptop.

Our IT guy kindly supplied me with a executable to install and configure the client under Windows and a config file and certificates for Linux.

Windows 7 worked immediately but under Linux I had to do some extra steps to get it working properly. I’ll document them here for future reference and maybe other people running in to the same issues.

I had previously installed OpenVPN under linux and hoped the config file would be all I needed. When running

I got the error message:

Options error: Unrecognized option or missing parameter(s) in configfile.ovpn:11: verify-x509-name (2.2.1)
Use –help for more information.

Some digging around showed the “verify-x509-name” command was implemented starting at OpenVPN version 2.3. Using

and the default repositories in Ubuntu the installed version was 2.2.1

To get the latest version, I uninstalled the current installed version using

then downloaded and untarred the latest version from the community downloads (at this time 2.3.6)

Installing should work this way:

./config && sudo make && sudo make install

but I ran into dependency problems. Some error messages came up regarding the LZO package.

configure: error: lzo enabled but missing

I found this page by Droidzone describing the dependencies and some useful information on how to find missing dependencies during future installs. Worth a read.

sudo apt-get install libssl-dev liblzo2-dev libpam0g-dev

will install the necessary dependencies. After this the installation went fine:

OpenVPN 2.3.2 x86_64-unknown-linux-gnu [SSL (OpenSSL)] [LZO] [EPOLL] [eurephia] [MH] [IPv6] built on Dec 24 2014

Manually Installing OpenVPN 2.4.7 On Ubuntu 16.04 Xenial

Why I am still on 16.04 when ubuntu has already launch 19.04 Disco dingo? Answer is I have 16.04 with all the necessary tools. Anyway while working on hackthebox my vpn started dropping the connection. So, I decided to troubleshoot the problem myself before changing the configuration. After googling for hours and trying every possible method written I couldn’t find a solution to my OpenVPN issue. Finally I decided to follow htb alternate tcp connection. And from here begins the journey of openvpn and openssl.

Possible Solutions I tried:

1. Tried restarting virtual box.
2. Tried regenerating my opvn file.
3. Tried updating my timezone.
4. Tried resetting my timezone in htb profile and again regenerating ovpn file.
5. Tried closing all connections and again connecting.
6. Tried reading almost all threads related to similar issue.

But the above two issues kept on coming.
Finally I decided to change openvpn configuration from UDP to TCP according to official htb website.

Alternate TCP Connection
By default, our network uses UDP port 1337. If this port is blocked at your location, you can try switching to TCP 443 by editing your .ovpn file.

So after changing configuration the moment I ran:

Output:
Options error: Unrecognized option or missing parameter(s) in vpnfile.ovpn:18: tls-crypt

Checked the version:

Install OpenVPN 2.4.7

Output:
checking for a BSD-compatible install… /usr/bin/install -c
checking whether build environment is sane… ye
schecking for a thread-safe mkdir -p… /bin/mkdir
.
.
[truncated output]
.
checking for SSL_CTX_new… no
configure: error: openssl check failed

Install OpenSSL

Note:
-openssl may or may not be needed. Since I uninstalled openssl to install latest version. Steps are mentioned below.
— /usr/local/bin is for locally compiled package and /usr/bin is for trivial binaries not needed in single user mode

Try Installing OpenVPN

For the error “configure: error: ssl is required but missing”

For the error “configure: error: lzo enabled but missing”

For the error “configure: error: libpam required but missing “

Note:
-Sudo is not used as the vm was running as root. Also we can specify manually where to install ssl libraries,etc. It is just a general workaround.

Solved OpenVPN-2.5.7 configure: error: lzo enabled but missing

Hi i am trying to upgrade my OpenVPN 2.5.3 to 2.5.7 version.

I followed below the instructions:

But at the ./configure section i got

I have installed below packages but no luck.
Any help would be appreciated at this point.

Here is solution i find from

_martin

To be honest I think that just butchers the FreeBSD installation and puts unnecessary symlinks across the FS. With that configure script you can tell it where the libs are, it will use is that way. You are also risking an issue if somebody/something removes those symlinks.

As a side note you can use ports to build it too as it was mentioned above. If you for some reason prefer different version than what is offered by ports you can use ports-mgmt/portdowngrade to select previous versions.

Noob trying to set up VPN ubuntu 10.10

Noob trying to set up VPN ubuntu 10.10

Post by JACKRABBit » Fri Mar 15, 2013 9:38 pm

I am trying to set up openvpn running on a VMware Workstation virtual machine using Ubunutu 10.10. I have tried to install openvpn using two different methods but both have not seemed to quite work for me yet.

The first way opening terminal and using sudo apt-get install oepnvpn with the following results:

$ sudo apt-get install openvpn
Reading package lists. Done
Building dependency tree
Reading state information. Done
E: Unable to locate package openvpn
linux@ubuntu:

After that didn’t work I went to the openvpn website and downloaded openvpn-2.3.0.tar.gz. from there I was able to extract then cd over to openvpn-2.3.0. From here I attempted to use ./configure && make && make install and received the following:

checking for ssl_init in -lpolarssl. no
checking for aes_crypt_cbc in -lpolarssl. no
checking for lzo1x_1_15_compress in -llzo2. no
checking for lzo1x_1_15_compress in -llzo. no
checking for PKCS11_HELPER. no
checking git checkout. no
configure: error: ssl is required but missing
linux@ubuntu:

From what I googled I believe this is an openssl problem so I went back into the terminal and tried

$ sudo apt-get install openssl
Reading package lists. Done
Building dependency tree
Reading state information. Done
openssl is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
linux@ubuntu:

So it seems that this is also up to date, I found two other options that said to go to system>admin>Synaptic Package Manager and try and hit reload. Also I tried to go to settings>repositories>download from>other>select best server but after searching it returns with «No suitable download server was found. Please check your internet connection.»

I’m unsure what to do after this point if someone would be kind enough to please advise how I would be able to get this set up properly that would be great!

Build OpenVPN on Ubuntu 14.04 from source code

Building/compiling OpenVPN from source code is not straight forward as you might think. The main problems are dependency issues.
