- nico 3y agoOld habits die hard I guess ;) Btw, had a classmate in college we called chungi (pronounced choon-ghee), we made some cool school projects together, including a videogame Thanks for the nc recommendation
- madacol 3y agocool! nc google.com 80 HEAD / HTTP/1.1 HTTP/1.1 200 OK ... Hint: write `HEAD / HTTP/1.1` and hit twice {ENTER}
- imoverclocked 3y ago“curl -v url” saves a lot of typing while also supporting https/vhosts/etc while still showing all of the communication and other debug info.
- Sophira 3y agoI'm actually a little surprised that worked; one of the major differences between HTTP/1.0 and HTTP/1.1 is that all HTTP/1.1 requests MUST include a Host HTTP header, so technically a HTTP/1.1 request without such a header is malformed.
- ttfkam 3y agoWeb servers have always had to be written for the web clients that existed, not how they should have existed. Sadly, a 100%-compliant web server (or client for that matter) would be greatly hobbled as to who it could communicate with on the real web. Although I do think the situation is far better now than it was 20 years ago.
- csydas 3y agoSeconding this; during my B2B support days, this was essential, especially, since as security got a bit crazy, not all systems had telnet installed anymore and you weren't always in a position to install it. Windows' best equivalent if it doesn't have telnet is from powershell: Test-NetConnection -Computername [hostname or IP] -Port [some port number] With the -Port flag, it will try to do a similar connection to a specific port.
