We have just implemented a second means to share files with others. As part of the new account system, you have your own group matching your NetID. This is new, if you find a bug, report it to me. If you find a security flaw, please report it immediately, if you exploit it to your or someone else's benefit or detriment, you will lose your account privileges on the servers.
How do I see who is in my group or which groups I belong
Go to https://charon.ece.cornell.edu, your account page will list who's in your group as well as any groups you're a member of.
How to add members to my group
On amdpool ONLY, you may type "sudo /opt/altoolsalttools/ece/add<em>to</em>mygroup add_to_mygroup <netid> <netid>" where <netid> is completely replaced with the netid of the person you wish to share files with. Yes, there are supposed to be two instances of <netid> in this command.
Now, in your home folder, you should do the following:
| Code Blocknoformat |
|---|
cd $HOME chmod 750 . mkdir project chmod 770 ./project chmod g+s ./project |
Poeple in your group can now see into your home folder and write to your $HOME/project folder.
...
It is imperitive that you minimally protect your .ssh folder, espeicially if you use public keys (GIT server uses them, you may also use them on your own) To protect:
| Code Blocknoformat |
|---|
chmod 700 $HOME/.ssh chmod \-r go-rwX $HOME/.ssh |
Your account security is your responsibility!
How do I remove people from my group
On amdpool only, "sudo /opt/alttools/ece/delete<em>from</em>mygroup delete_from_mygroup <netid>".
I have sudo! Can I do other things like install software?
No, and I see logs of your attempts and may lock your account if I see to many attempts! ;)
