Read and UNDERSTAND the following guidelines: failure to follow them will at the very least cause your account to be terminated, and could possibly result in a jail sentence under the Federal Computer Crime statutes. WARNING: *You* are responsible for usage of your account. 1. Make sure your password is not found in a dictionary, nor one from any popular works of fiction. I will periodically run a password checker and sending mail to individuals whose passwords are found. 2. Make sure your home directory and .profile, .login, .cshrc, .kshrc, and others that you execute regularly are not writeable by anyone other than yourself (these are the files which the various shells execute at login time to initialize your environment; you can edit them to suit your tastes, but if others can write to them, they may turn them into trojan horses). In addition, .rhosts should not be *readable* by anyone other than yourself. This is a file that is used to define trusted hosts on the network, and in general, should not be used at all. If you need to allow access to your files for specific individuals, I'll create groups that will allow you to set group permissions. Currently, allowing group access is the same as allowing world access, since you're all in group "users". See man page for "chmod" for more information. 3. Only one login at a time per account. Accounts are for individuals, not groups, so you should only need to login on one line anyhow, but in any case, phone lines are the scarce resource on agora, and pigs are not welcome. Simultaneous logins will result in account termination after a single warning. 4. As far as cracking is concerned, you may attempt to break *local* security, if and only if: 1. You let me know ahead of time of your intent and direction of attack. If you don't do this, and I discover your efforts, I will assume the worst. 2. No destructive or otherwise malicious results occur as a result of your efforts. This includes denial of service (i.e. using all the disk space, being a cpu hog, etc.). 3. Any successes are reported to me *immediately*. 4. Successes are not used as an opportunity to be nosey (i.e. respect other users' privacy). Failure to follow these rules will result in at minimum, a loss of your account on agora with no refund and a public notice of your termination posted to pnw.general. If the offense is prosecutable, it will be. Absolutely no attempts at breaking security over the network will be tolerated! Any such attempts will be prosecuted. Period. Such attempts reflect very badly on agora and I do everything I can to preserve its reputation. Note: attempting to connect to systems (i.e. telnet, rlogin, ftp) to which you have no reason to believe you are welcome to do so (i.e. they are not listed somewhere as being publicly accessible), may be considered an attempt to break security over the network. Your account status will be up to the remote admin, regardless of whether or not you actually tried to login to the system.
