Data Solved: SSH-KEYGEN doesn't work
Hi,

Am running the following commands on our server to generate a key for passwordless SSH, however we are getting 100% blank key files.

E.g. when looking id_dsa.pub or id_dsa they are 100% empty - the files get created, but contain no content and have a file size of 0b.

mkdir ~/.ssh
chmod 0700 ~/.ssh
ssh-keygen -t dsa -f ~/.ssh/id_dsa

*no pass phrase is put in*

Your identification has been saved in /root/.ssh/id_dsa.
Your public key has been saved in /root/.ssh/id_dsa.pub.
The key fingerprint is:
xx:xx:xx:xxx........

And then the files id_dsa amd id_dsa.pub are both empty. There but empty.

Any ideas?

I have tried all the various different options for CHMOD at the start, 777, 755, 666 etc ... I have also tried both with and without a password. All of them still give me an empty file. Smilie

Problem Solved

My bad. Thanks all.

The /root user directory was full.
It wouldn't allow any more data to be written to it.

Is your SSL OpenSSL or something commercial? Your listing works perfectly fine for me. Try 'echo something > ~/.ssh/id_dsa', just to see if the system itself is having problems writing to that file for some reason.

[edit] Hah, I knew it.
