This is the result for running either the telnet version or the standalone version of the code.

happens in iTerm2 on OSX 10.6.8

After exiting the animation my cursor has vanished, and does not return. OH NOES!

Needs binding to IPv6 as well as IPv4.

I'm trying to write a systemd service/socket file for nyancat right now, but I noticed the processes don't quit after the socket is closed.

After talking to the people from #systemd on Freenode it seems the process should exit when it gets an EOF, but nyancat does not. I think it should.

It would be nice if you would consider adding proper source release tarballs,
as GitHub auto-generated tarballs are not immutable. This is an issue [1] for
operating systems creating packages for nyancat. Thanks in advance.

Mention that nyancat is available on MacOS using homebrew, here is the link for the homebrew package. Also add the nyancat gif as also mentioned in pull request #60

Salve,

I dunno if you give a damn, but my nyan.sh script has faithful reconstruction of the cat and adapts to the terminal window. It also adapts the RGB palette. Perhaps you want to glean some of my tricks from nyan.sh

If neither TERM variable set nor -t option given nyancat crashes with SIG_SEGV.

Probably it does 'cause at nyancat.c:353 it tries to strcpy() from null-pointer nterm.

As I see on https://nyancat.dakko.us/ :

Due to bandwidth limitations, the Nyancat telnet server has been shut down.

Can we (Everyone with a server and spare space) help by hosting it ? You have the domain name, maybe a small script for mirroring around a public instances list could be nice :)

It would be a shame that this piece of internet history (mine for the least) dies like that.

It would be nice to add screensaver support to vlock (console lock program): it is about writing a plugin (a .so library) which should be placed under /usr/lib/vlock/modules for debian distro. I am able to write the plugin however I am not sure if it will fit in a debian .deb package (files conflict?)

What do you think?

OpenBSD 5.9 will ship with pledge(2). It's a security mechanism to restrict what programs are allowed to do. Most of the base system has been patched to use it, and work has started on pledging relevant third party programs in ports. It's defined in unistd.h which nyancat has already an include for.

For nyancat, it would look like this :

#if defined(__OpenBSD__)
    if (pledge("stdio tty", NULL) == -1) {
        err(1, "pledge");
    }
#endif

Would you be willing to merge this if I submit a PR?

It doesn't seem safe to be running this with root privileges :)

Ideally, you could run this on a different port and have a daemon just connect the ports together, with safe code able to run on port 23 as root.

Option negotiation hangs if the remote client WILL send the terminal type, but WONT negotiate window size, or vice versa.
Looks like it's because the timeout alarm is cancelled when one of the two extended options are received (line 446).

As the title: I would help with a pull request, but I can't understand how it should work.

Thanks in advance.

is it possible to change the color? instead of using the default colors

I followed you on twitter last night and requested that you follow me back so I could message you (I wasnt given the option to direct message you), I am a fan of your projects and needed your expertise on one of my projects.

P.S this was the only way I saw to contact you

brew formula?
