Mini-FAQs:

Q: I would like an account in the Hewitt Lab. How do I get one?

A: Contact me, shannon@astro.cornell.edu

Q: I would like to hook up my laptop or desktop to the network, how is that done?

A:Just plug in an ethernet cable and set your network configuration to use DHCP. Our DHCP server will detect your computer on the network and dynamically assign a IP number.

Q: What about the wireless network?

A: We have both Astronomy and astronomy wireless networks in Space Sciences. The Astronomy network requires a password, come see me if you need this password.

Q: How do I check my mail remotely (or from a my personal computer here in Space Sciences)?

A: Use Webmail. Here's the link...https://astrosun2.astro.cornell.edu/horde/imp. Webmail is also linked from our departmental web site www.astro.cornell.edu under Resources. Some people prefer to login remotely and use pine.

Q: What is ssh or scp? Do you offer ftp or telnet?

A: ssh stands for secure shell, scp secure copy. They are the secure replacements for telnet and ftp. Ftp and telnet send data using clear text meaning that anyone with a packet sniffer can discover your password. Everyone is strongly encouraged to use ssh and scp whenever possible. You can find free ssh and scp programs here http://www.openssh.org.

Q: I need to update the course web site for astroXXX. How is that done?

A: First make sure you have the correct permissions so you can edit the files you need to, check with Tom. Then log into falcon.astro.cornell.edu and change your directory to /home/web this will put you in the top level directory for the Cornell Astronomy website. From there you can cd whereever you need to go say, academics/courses/astro233 for instance. More details are available in the Computing at Space Sciences site in our dept. web pages.

Q: What's my hard drive quota on the server?

A: We don't set any quotas. However I monitor disk space usage and request that people not abuse this privilege.
