On website, it writes:
You don't look like our agent!
We will only give our flag to our Agent 95! He is still running an old version of Windows...
Agent 95 ? Maybe its window 95 user-agent ?
On https://en.wikipedia.org/wiki/User_agent we can see that the user-agent or Window95 is Microsoft Internet Explorer/4.0b1 (Windows 95)
We access to the website with this user-agent and we can read the flag:
$ curl -h "^Cft Internet Explorer/4.0b1 (Windows 95ows 95)" http://jh2i.com:50000/
[tom.rorato@linux Downloads]$ curl -H "User-Agent:Microsoft Internet Explorer/4.0b1 (Windows 95) " http://jh2i.com:50000/
flag{user_agents_undercover}
[...]
The flag is: flag{user_agents_undercover}
