Getting Package Control for Sublime Text 3 installed when behind a corporate firewall can be a challenge, so much so that I keep forgetting how to do it whenever I get a given a new computer to work on – so time to write this down!
- Install CNTLM – once installed, open the cntlm.ini file (C:Program Files (x86)Cntlmcntlm.ini).
- Set your Username to your domain username and your domain to your domain name.
- Put a # in front of the password line.
- Fill in the correct IP and Port number for your corporate proxy. (# out the other if there’s only one).
- Save the ini file.
- Open a command line and type
cntlm -I -M http://test.com
(note, you may need to cd to the path that cntlm is installed in first)
- Copy the hash that gets returned into the ini file on the PassNTLMv2 line and remove the # from the beginning of that line, then save the ini file.
- Run services.msc and find the cntlm service and start it.
"http_proxy": "localhost:3128"to your Sublime Text User Settings file.
- Save that file.
- Copy the installation text from the Package Control Website and paste it into a new file in Sublime Text.
- Search for
urllib.request.ProxyHandler()and in between those brackets add:
- Now, copy all that text and paste it into the Sublime Text console (Ctrl+`) and hit return.
- You should see package control get installed successfully! (yay) once done, hit Ctrl+Shift+P and type packin and hit return and choose some packages to install!
Phew, all done!
Package Control behind a corporate proxy, if you have any other troublesome apps throwing 407 Authentication errors, then just configure them to point to
localhost:3128 and ensure that the cntlm service is running – oh and don’t forget to update the hash in the cntlm config should you ever change your password 🙂
