Hi,
I have setup the SSH keys for passwordless login as u mentioned above. But when I use the automated sftp script in crontab it fails when executed manually it executes.

Please let me know what might be the issue.

But in this case it will prompt you for the passphrase while refreshing the .profile!!

In my case, even after removing all the files in ‘.ssh’ folder in both client and server, the ssh works perfectly. Can someone explain about this?

scp -pq ./copy:temp.txt user@server:/home/user/bin/

While transferring the files from one server to another, if the file contains a colon(:) then it is assuming the file name before colon as server name and giving the error “host nor service provided, or not known”

For ex: scp -pq copy:temp.txt user@server:/home/user/bin/.

If the file name is “s:temp.txt”, it is taking “copy” as server name… Any suggestions on how to resolve this issue?

And for those of you on hp-ux 11.31, (or other O/Ses) resist the tempation to add these lines into your .bashrc / ,bash_profile, because you will, like me, lock yourself out :-

exec /usr/bin/ssh-agent $SHELL
ssh-add

Shame :(

We wish to devlope the software with cd-lock protection.

- Installation process

I feel like an idiot.
chmod 600 ~/.ssh/authorized_keys solved the problem, meanwhile I have 2 other machine that have no problem with 755 permission…

Thanks :)

#ssh-copy-id -i //to copy your keys
Insted of DSA key RSA is very strong so always prefer RSA key

I saw the program. Run the following commands to deal with it.

chmod 701 ~/
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

Hi it works fine for me ,but everytime i close the putty and try to do scp again it asks for the passphrase again .so each time i login afresh i have to start the ssh-agent and the ssh-add
….like i m wondering if there is a better way to do it?

While generating the key donot put any passphrase, just press ENTER.
then does not prompt for password.
it worked for me.

I followed the procedure and its perfect.
I have another question.
Requirements: I want to assign my root account with a DSA key so that only with that specific DSA
can use the root account
How can I achieve this?

Thanks
