How to install checkpoint snx (SSL Network Extender) – Deepin 15.4 desktop

How to install checkpoint snx (SSL Network Extender) in Deepin 15.4 desktop 64bits

Kernel version of Deepin

Linux test-ebook5 4.9.0-deepin5-amd64 #1 SMP PREEMPT Deepin 4.9.8-5 (2017-05-02) x86_64 GNU/Linux

After the installation of jdk_1.8.0_u112 (64bits), firefox 52 ESR, snx_install.sh (checkpoint).

java version “1.8.0_112”
Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)

Mozilla Firefox 52.1.2

The snx is not working with the following problem:

snx: error while loading shared libraries: libpam.so.0: cannot open shared object file: No such file or directory

Debug for this problem:

sudo ldd /usr/bin/snx
linux-gate.so.1 (0xf7719000)
libX11.so.6 => /usr/lib/i386-linux-gnu/libX11.so.6 (0xf75a7000)
libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf758a000)

libXdmcp.so.6 => /usr/lib/i386-linux-gnu/libXdmcp.so.6 (0xf7362000)

Do this for fixing this problem:

sudo apt-get install libstdc++5:i386 libpam0g:i386

After the fix, check again:

CVE-2017-7494 – Samba 漏洞

漏洞警报(CVE-2017-7494)

All versions of Samba from 3.5.0 onwards are vulnerable to a remote
code execution vulnerability, allowing a malicious client to upload a
shared library to a writable share, and then cause the server to load
and execute it.

Manual fix/Workaround

Add the parameter:
nt pipe support = no

to the [global] section of your smb.conf and restart smbd. This
prevents clients from accessing any named pipe endpoints. Note this
can disable some expected functionality for Windows clients.
