#proxy #network

background

We need proxy to visit outside network, and it need verification.
But a lot of software, like git, nodejs, npm and so on sometimes cannot connect to outside network without proxy.

Solution

Install proxy software like cntlm to make local pc a proxy server if local pc has the verification to connect outside network.

Installation and configuration

1. Install cnltm

install setup.exe from below link
cntlm sourceforge

2. Config cntlm.ini

Username x30029338
Domain china.huawei.com
Proxy proxyhk.huawei.com:8080
NoProxy localhost,127.0.0.*,10.*,192.168.*,*huawei.com
Listen 3128
Gateway yes
Allow 90.90.0.0/16

3. Generate password

Execute command ".\cntlm.exe -H -u x30029338", and type in your password in the prompt. You wil get password which is needed in the cntlm.ini from the output of previous command.

Auth NTLM
PassLM *****
PassNT *****

4. Start cntlm

execute ""regedit", open registry editor, enter HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\cntlm\Parameters,
change AppArgs' value to "-f -c "C:\Program Files (x86)\Cntlm\cntlm.ini"
open admin powershell, execute command "net start cntlm"

Config Proxy using cntlm proxy server.

after we start the cntlm in the pc, we can set proxy in our develop environment.

export http_proxy=http://$pc_ip:3218 
export https_proxy=$http_proxy
