| Mail facilities and ask for root on your machine | ||
| Local password: “passwd –l” | ||
| Ask for a copy# from the main office (WeH4212) | ||

| help@cs.cmu.edu | |
| Help desk (x8-4231) “how do I…?” | |

| Costs money: | ||
| new kerberos Ids | ||
| printing | ||
| network ports | ||
| software | ||
| backups | ||
| dialups (1-800) | ||
| Free: | ||
| accounts on machines | ||
| WaveLan | ||
| Log in, get a “ticket” | ||
| tokens, klog, aklog | ||
| Tickets are good for 25 hours | ||
| Used for: | ||
| authentication | ||
| encryption | ||
| Renew forever: kauthd username | ||
| network/clock failurečkerberos failurečlogin failure | ||
| Access control: | ||
| fs la /afs/cs/user/colohan | ||
| fs sa /afs/cs/user/colohan rlidwka | ||
| Ignore unix permissions! | ||
| Careful with mail directory permissions! | ||
| Turn tickets into tokens with aklog | ||
| Quotas: | ||
| fs quota /afs/cs/user/colohan | ||
| telnet jeeves | ||
| Backups in ~/OldFiles | ||
| Always log into SCS domain! | ||
| Use pop3 to your maildrop (ux#.cs.cmu.edu) | ||
| imap/Exchange in beta | ||
| Do not run a client on the ux# servers! | ||
| Printing | ||
| Printers off of \\monolith | ||
| File sharing | ||
| AFS | ||
| FAT Partition | ||
| Peter Dinda’s FAQ | ||
| Choose a window manager | ||
| edit ~/.xinitrc | ||
| Depot | ||
| It “owns” /usr/local | ||
| make your own collections | ||
| become a misc maintainer | ||
| Getting local root if your machine dies | ||
| vmware | ||
| Local disk is /usr0, shared disk is /mnt/share | ||
| man cdrecord | ||
| A reminder: ZINMT | ||
| Zephyr Is Not My Thesis | ||
| To receive: zwgc (started by default) | ||
| To send: zwrite colohan –m “Lunch?” | ||
| Emacs zephyr mode | ||
| FZQ | ||
| Zephyr archive | ||
| Common “instances”: | ||
| help.*, chat.*, newsbites, graffiti, sddd, *.d, facilities.announce, facilities.discussion | ||
| Don’t sign messages | ||
| Don’t take people too seriously | ||
| Andrew/MIT zephyr use is different | ||
| cmu.cs.scs: important announcements | |
| cmu.cs.*.announce: new software or changes | |
| cmu.cs.general: general interest items | |
| cmu.misc.market: fun fun fun! | |
| On unix, use localhost as news server | |
| On Windows, use dnntpd.srv |
| ssh –X colohan@ux4.sp.cs.cmu.edu | |
| scp gs138.sp:~/foobar ./ | |
| Very useful from off campus! | |
| Create a .maildelivery file on your maildrop machine (ux#) | |
| man maildelivery | |
| Use username+foo@cs.cmu.edu | |
| man spamassassin-maildelivery | |
| Refill the printers | ||
| Don't leave the printers jammed | ||
| Don't print big jobs during peak hours | ||
| Ask facilities before you do strange things | ||
| broadcast packets | ||
| move hardware | ||
| commercial anything | ||
| looking through other people's files: get explicit permission first | ||
| look for permissions in their .plan | ||
| ask them directly | ||
