wget proxy: set the http_proxy environment variable

Posted by jpluimers on 2021/11/05

[WayBack] WGET 1.11.4 for Windows (win32) as well as many other tools use the [WayBack] http_proxy envonment variable to specify the http proxy settings.

To set it to a locally running Cntlm proxy, use this syntax:

set http_proxy=http://localhost:3128

NTLM proxy authentication and Dropbox: need to try NTLMAPS and cntlm

Posted by jpluimers on 2021/11/01

Interesting:

Some corporate networks are behind HTTP proxy servers that use NTLM authentication. Dropbox currently doesn’t support this kind of proxy authentication. However, some users have reported some success using an intermediate proxy, such as [WayBack] NTLMAPS or [WayBackcntlm, to get Dropbox running on their network.

This article explains steps on various systems to install proxies that support NTLM authentication: [WayBackAllow Dropbox to Authenticate With a NTLM Proxy Server – The Unofficial Dropbox Wiki.

Need to try these. Maybe they work for Copy.com too (:

Facebook ist in Bezug auf Kundenzufriedenheit und Vertrauen in Umfragen zieml…

Posted by jpluimers on 2020/10/16

Nice thread as it talks a bit about how keep your own stuff secure with companies doing MitM, or have VPN infrastrcuture.

[WayBack] Facebook ist in Bezug auf Kundenzufriedenheit und Vertrauen in Umfragen zieml…

Most larger TLS based web-sites now have HSTS so detect MitM.

Having a proxy locally helps checking the certificates.

Corporate laptops usually has device management. If they use MitM, their root certificates are usually put back automatically. But not all software uses the same root certificate store (:

In the past, I have used [WayBack] cntlm, or VPN (routing only corporate traffic over VPN).

There are corporate VPN variants, which take over the complete routing table or even run arbitrary scripts as root on your box on connect in order to do “endpoint validation”. And then there is OpenVPN, which routes the traffic that the company shall see to the company and lets you use normal connectivity for the rest.

You want openvpn, in all cases.

Another trick I have used is to VPN/SSH out of a corporate box and route some of the traffic over it.

Finally, for some larger corporate VPN software, there is an open source replacement that has better configuration options: OpenConnect supports AnyConnect, Juniper and GlobalProtect.

Dixin’s Blog – Use Fiddler with Node.js

Posted by jpluimers on 2019/10/30

[Archive.is] Dixin’s Blog – Use Fiddler with Node.js Fiddler is an useful HTTP proxy debugger on Windows. It would be nice if it can work with Node.js applications. To do this, just need to proxy Node.js requests through Fiddler… on port 8888.

There is a snippet for it at github/Dixin/CodeSnippets/…/fiddler.js (now moved to [WayBack] github.com/Dixin/Blog/…/Blog/Dixin.Nodejs/fiddler.js)

It complements a few posts I’ve written about Fiddler using port 8888 as a proxy before:

Using Chrome on Windows with a different proxy server than the system one (which is used by Internet Explorer)

Posted by jpluimers on 2019/10/25

By default, Chrome uses the same proxy server as Internet Explorer: the system one that your Chrome settings page accesses from chrome://settings/search#proxy through this command-line call:

"C:\Windows\system32\rundll32.exe" C:\Windows\system32\shell32.dll,Control_RunDLL C:\Windows\system32\inetcpl.cpl,,4

There is no GUI way inside Chrome to change this, but there is a command-line parameter: --proxy-server="ipaddress:port"

So create a new shortcut to Chrome, then you can change it.

This comes in very handy if you want to test

  • some sessions through for instance Internet Explorer going through HTTP Fiddler (that defaults at localhost:8888)
  • other sessions through Cntlm (that defaults to localhost:3128)

Some background information:
