Do not run anytermd as root.
Anyterms code has not been audited for security. It is almost certainly possible to cause it to crash by sending it invalid input, and experience suggests that this sort of weakness can also be exploited to allow arbitary code execution.
Note that all CGI applications and similar programs are subject to this sort of problem, though some are better written than others. The Anyterm code does not need run with a higher priviledge level than any other web application, so weaknesses in Anyterm do not put your system at any higher risk than weaknesses in any other web application would.
Avoid exposing anytermd directly to the Internet.
anytermd should be used only as a backend service, reachable only via a frontend HTTPS proxy, such as Apache, that requires authentication. http://anyterm.org/1.1/install.html gives examples of how to set this up.
A more complete and up-to-date discussion of security issues in anytermd can be found at http://anyterm.org/security.html.
If you just want to test Anyterm, you can do:
If you want to set up SSH-over-HTTP access on localhost:8022, you might run it as:
anytermd --command "/usr/bin/ssh -o your-username@localhost" --port 8022 --user nobody --charset utf-8 --local-only
Anyterm is more fully documented on its web site, http://anyterm.org/. The web site may be more up-to-date than this man page.
