Ubuntu 16 - VMWare Player 12 - GCC Not found

First solution
cd /usr/lib/vmware/modules/source 
wget https://github.com/mkubecek/vmware-host-modules/archive/player-12.5.9.zip 
unzip player-12.5.9.zip 
cd vmware-host-modules-player-12.5.9/vmmon-only/ 
make 
cd ../vmnet-only/ 
make 
cd .. 
mkdir /lib/modules/`uname -r`/misc 
cp vmmon.o /lib/modules/`uname -r`/misc/vmmon.ko 
cp vmnet.o /lib/modules/`uname -r`/misc/vmnet.ko 
depmod -a /etc/init.d/vmware restart


Second solution

mkdir ~/vmmodules #create a temp folder and copy files.
cp /usr/lib/vmware/modules/source/vmnet.tar /usr/lib/vmware/modules/source/vmmon.tar ~/vmmodules/ 
# make the modules manually 
tar -xvf vmmon.tar 
cd vmmon-only 
make 
cd .. 
sudo cp vmmon.o /lib/modules/`uname -r`/kernel/drivers/misc/vmmon.ko.gz 
tar -xvf vmnet.tar 
cd vmnet-only 
make 
cd .. 
sudo cp vmnet.o /lib/modules/`uname -r`/kernel/drivers/misc/vmnet.ko.gz 
#Then reload the modules and restart vmware service, vmplayer should works now. 
sudo depmod -a 
sudo systemctl restart vmware


Thrid solution

#install the right version of gcc
$sudo apt-get install g++-4.9 

Trick

$sudo sed 's/gcc version 5.4.0/gcc version 6.4.0/' /proc/version > /tmp/version
$sudo mount --bind /tmp/version /proc/version
$sudo vmware-modconfig --console --install-all
$sudo umount /proc/version && rm /tmp/version

SSH Skip port forwarding

vs ngrok
Serveo is an excellent alternative to ngrok. Serveo was inspired by ngrok and attempts to serve many of the same purposes. The primary advantage of Serveo over ngrok is the use of your existing SSH client, so there's no client application to install.

Other slight advantages include preservation of URLs across reconnect for free (ngrok allows this only for paid accounts) and in-terminal request inspection and replay (ngrok uses a web interface).

vs OpenSSH

Using Serveo instead of OpenSSH frees you from having to configure and maintain a server. It also handles HTTPS and subdomain generation, two features that complicate a typical SSH port-forwarding setup.

Server Side (PCX Need root permission)

$sudo vi /etc/ssh/sshd_config

AllowTcpForwarding yes
GatewayPorts yes


$sudo firewall-cmd --add-port=7004/udp [--permanent]
$sudo firewall-cmd --add-port=7004/tcp [--permanent]

Target PCB

$ssh -f -N -R 7004:127.0.0.1:22 -l user_PCX -p port PCX(ip/domain name)
This means open port 7004 on PCX forwarding to port 22, PCX will start to listen on port 7004.

Source PCA
$ssh PCX(ip/domain name) -l user_PCB -p 7004

Enjoy!
