i6 Services: FAQ
i6 Services: FAQ
Q. "I forgot my password, what do I do?"
A. Visit our password reset page for instructions to reset your password.
Q. "I think I have the right password, but every time I try to connect to i6, it says permission denied."
A. If you're on a Mac or Linux, be sure that you are including your NetID in your ssh command: ssh NETID@i6.cims.nyu.edu. We capitalize NETID in our documentation for emphasis, but you need to type it in all lowercase. Secondly, make sure that you're connecting to i6.cims.nyu.edu and NOT access.cims.nyu.edu. If this still fails, attempt a password reset.
Q. "When I try to access my site, it tells me it's Forbidden."
A. 99.9% of the time this is a Unix permissions issue that you can resolve yourself. See our Interact page for a brief look at setting permissions, as well as a hint to get you started with the permissions of you index.html file.
Q. "I accidentally deleted my public_html folder. What do I do?"
A. Your public_html "folder" is actually a symbolic link in your home directory to your web directory. If you've deleted this link, you can recreate it by SSH'ing to i6 and running the following command: "cd; ln -s /web/NETID public_html" where NETID is your NetID in lowercase letters.
Q. "When I attempt to SSH to i6, I get a big scary message about a public RSA key problem, and can't connect."
A. If you connected to i6 in a past semester, it's possible the i6 hardware has changed since then, which could have resulted in a new RSA key. An RSA key is essentially something to identify a remote machine so that you know you are connecting to the machine you intend to, and not a machine that has hijacked the hostname of the machine. You can confirm the legitimacy of the machine you're attempting to connect to as actually being i6 by checking our Secure Connection Verification page and looking at the current fingerprint value for i6: https://cims.nyu.edu/webapps/content/systems/userservices/netaccess/secure_verification
To get around this error, you will need to open up your "known_hosts" file and delete the lines relating to i6. The known_hosts file is usually found in the ~/.ssh/ subdirectory. On Mac's it's usually something like /Users/your_local_username/.ssh/known_hosts.
If you don't connect to other services besides i6, it is safe to remove all the content of this file to start fresh.
Q. "Despite all the settings being correct, my SFTP program such as Fetch will not connect."
A. See the above question and check for an RSA key in your known_hosts file, and delete the lines regarding i6 if they exist, then try again.
Q. "My site itself (not my i6 account) has a password on it and I forgot what it is."
A. Your site most likely has a .htaccess file in place. A .htaccess file is one which allows you to control who can or can't access the site. This .htaccess file would most likely be located in your web directory accessible via /home/NETID/public_html/.htaccess. If this file exists, you can modify it to your liking, or just delete it. Please consult Google for basic .htaccess usage.
Note that some instructors include the existence of an .htaccess file as part of your curriculum. When in doubt, ask your instructor if it is important to him/her that your website be restricted by a .htaccess file.
