Segfault Returns! Free Disposable Or Persistent Kali Server!

in News

Hello!

Looks like a lot of fun to me. It's called The Hacker's Choice. (THC)

You login via ssh from anywhere and instantly get a free Docker container instance in SF or DE depending on where you might be coming from. The instances run Kali with a zsh as the shell. Exits are via tor and various VPNs. Looks like IPv4 only. There is a channel on Telegram.

Instances are "disposable," which means that instances are deleted when you log out. They claim, "NO LOGZ."

The login message is very helpful. The login message provides ssh tweaks for setting up persistent instances. It also clarified questions I still had even after reading the THC web page.

Lots of stuff is tricky/fun. As just one tricky/fun example, when you log in you are in /root, but root's persistent home directory is /sec/root. If you do want files to persist between visits, you have to know to cd from /root to /sec/root. Or just cd without any argument also works, since $HOME=/sec/root.

There is an option to pay, apparently a one-time $100 amount, to get service level upgrades on bandwidth, processor, memory, hdd access speed, and storage.

History

This is the resurrection of our 1997 'segfault.net' root server. The server of '97 served as a stepping stone for many hackers, coders and researchers. It's where we hosted phrack, Team Teso, HERT, Hack in the Box, the first encrypted IRC network and many others.

I shut it down in 2019. Now it's back.

Here's a link to the HN article where I found THC.

If you log in, you might find my Hello in /everyone/hello.txt.

Happy Saturday!

Tom

    I logged in at segfault. Now I see

    included in the login messages. As noted above, I used to find myself in /root. Now I was in /sec/root after I logged in. Could it be that zsh remembers where I was? Can I still write?

    By the way, I was in /root when I closed the connection but ended up back in ~ (/sec/root) when I logged in again after closing the connection.

    Hmm. Fun/tricky. Maybe I'm just missing something simple. :)

    Well, I am guessing that you @FatGrizzly might be on the DE server, and that the two segfault servers might not be 100% in sync for the /everyone directory. Maybe I might try to login to segfault.net from Amsterdam instead of from here in Sonora, MX. Coming from Amsterdam might get me an instance on the DE segfault server.

    Thanks @FatGrizzly!! :)

    Looks like the new ABUSE message might be for everyone, not just for me. I was imagining it might be for me cuz I ran the yabs yesterday.

    But, no LowEndTalk message from @FatGrizzly here either. Maybe I'm not on the SF server. And maybe they have more than two servers. Or something else. Oh well, fun/trucky or tricky/fun.
