HI all,
I've got a question about using public key authentication. I've been
looking on the maling list archives and FAQ, and it's probabely me, but
I can't find an answer to this question. Sorry if I am the 1000th person
asking this question, I know that's annoying, but I can't find the answer.
I'm using public key authentication to access some servers through ssh.
I put my private key on a usb memory stick cause I need to access the
servers from different locations (when on holiday, from my home, from my
office, etc). I've password protected the private key with a very long
passphrase which is virtually unguessable. To be able to access the
private key from multiple OS'es, the fs of the memorystick is fat16.
Fat16 does not support any rights on files, so mounted on linux, all
files have 0755 permissions. The ssh client doesn't accept private keys
with 0755 permissions though. Setting -o StrictModes=no when invoking
the client does not seem to work (bad configuration option).
Is there any way around this? If there is not, it would mean it is
impossible to use public key authentication from multiple locations
since memorysticks have to be formatted in fat16 to be able to use it on
multiple OS'es.
Even if I would format the memorystick with a ext3 fs, which would make
it useless on windows, the problem would still persist. UID's accross
multiple linux machines are never the same. Having the private key owned
by some user with mode 600 would make it useless on another system since
the same uid probabely belongs to another user on that machine.
I hope somebody can help me with this problem, thanks for you patience.
Cheers,
Dolf.
