UNIX for Dummies Questions & Answers

Crap, I messed up. One typo and I set the permissions to 655 instead of 755. Now I'm locked out of the remote server. How do I fix this?

EDIT: Never mind, fixed it. I'm going to remove the .ssh directories on all machines and restart the process of key generation.

6 means RW read-write... not good on any directory unless you wish no access... you need on a directory the x (for execute) to traverse the directory...

It is still not working. The two servers (Faust and Hornet) may have different permissions. I can copy files in a Hornet terminal to/from Faust, but I need a password despite the key. I cannot copy files in a Faust terminal to/from Hornet because of the key; no password prompt, but scp hangs.

?
Do you mean you made a copy/paste in a GUI?

No, I mean scp [fileonhornet] [faustuser@faustserver]:[destination]

Lets try to concentrate on ONE server (at a time...), when I get stuck (it happens sometimes, the worst case is when it works one way only (that was my first post...)).
choose your local and your distant server.
Read again carefully Bakunin's post (explains far better than I can... thanks Wolf!).
Best would be to start all over once more.
this time I need to know if you are root (yes there are some admin that configure sshd not allowing root to use ssh...), if not can you su/sudo to have admin priviledge (we might need it...).
As you user can you use any other ways to connect except ssh ( telnet, remsh...) if so, what, the idea is to see without ssh if all is OK
If you can't I will need to think a bit more....

Alright, a new development has come to light. It seems I don't have enough space on Hornet to copy all the files I need. There's about 273 GB worth of files, and apparently I only have a few MB of space. On a 300-TB supercomputer. In whose mind does that make sense?
