Use CNTML to pass through NTML proxy

Leave a reply

Lots of company require end users to use a proxy to access internet. Some of them are using NTML proxy such as ISA. But some software such as Xshell, putty are not supporting NTML proxy.
So we can use CNTML to pass through NTML proxy.

Official website：http://sourceforge.net/projects/cntlm/
You can also refer to wiki：http://sourceforge.net/apps/mediawiki/cntlm/index.php?title=Main_Page

1. Download CNTML. I suggest to download the zip version due to users may not have admin rights.
2. Unzip it.
3. Modify configuration file cntlm.ini，Please note that the password is in plain text and it’s a security risk：

Username: Your domain username
Domain: Your domain name
Password : Your domain password. (It seems that if you have # in your password, you may get some problem)
Proxy : You NTML proxy address, such as 10.0.0.1:8080
Listen cntlm: By default it’s 3128

4. Create a shortcut for cntlm.exe, and then right click the shortcut, choose property. And add ” -c cntlm.ini” at the end of target. Otherwise CNTML will try to laod the configuration files in C:\Program Files\cntlm中的cntlm.ini, and you’ll get an error.
5.Double click the shortcut to start CNTML. And then open task manager, you can find that cntml is running.
6. In Xshell, create a new proxy which is 127.0.0.1:3128

This is the fastest way, but requires a decent internet connection.

Shut down all your running VM’s and enter Maintenance Mode.

Install FreeBSD on Linode VPS

1 Reply

I’m a FreeBSD fan, I prefer to use FreeBSD as the web server if possible.
In the pass Linode doesn’t support FreeBSD, people who want to use FreeBSD have to choose Digital Ocean or other service provider.
And in earlier this year, Linode has migrated all VPS from Xen to KVM, and it made installing FreeBSD on Linode VPS possible. But FreeBSD is not official supported by Linode. You can’t deploy FreeBSD via Linode control panel. So I wrote this article to share my experience about how to install FreeBSD on Linode.

1. Add a new linode VPS.

2. Go to the dashboard, and create a new vDisk.

Fix”Video Schedule Internal Error”blue screen problem

1 Reply

I just set up a new Z170/6700K machine which is running windows 10. But I always got the blue screen with error message Video_Schedule_Internal_Error.

bluescreen

After investigation, I found that this problem was caused by the latest Intel Video card driver win64_15407.4279.
The workaround is to change the shared memory settings for the Intel Video card. You need to assign 128M memory for per 8G memory. It means:

If you have 8G memory, assign 128M memory for the Video card;
If you have 16G memory, assign 256M memory for the Video card;
If you have 32G memory, assign 512M memory for the Video card;
