I have a strange issue where SSH won't properly connect with a private-key if the key file is in certain directories. I've setup the keys on a set of servers and the following command
ssh -i /root/privatekey firstname.lastname@example.org
works fine and I login to the given host without getting prompted by a password, but this command:
ssh -i /etc/keyfiles/privatekey email@example.com
gives me a password prompt. I've narrowed it down that this behavior occurs in only some sub-directories of /etc/. For example
/etc/httpd1/ gives me a password prompt but
/etc/httpd/ does not.
What I've checked so far:
- All private key files used are identical (copied from the original file).
- The private key file and directories used have identical permissions.
- No relevant error messages in the server/client logs.
- No interesting debug messages from
ssh -v(it just seems to skip the key file).
- It happens with connecting to different hosts.
After more testing it is not the actual directory name. For example:
mkdir /etc/test cp /root/privatekey /etc/test ssh -i /etc/test/privatekey firstname.lastname@example.org # Results in password prompt cp /root/privatekey /etc/httpd # Existing directory ls -ald test httpd # drwxr-xr-x 4 root root 4096 Mar 5 18:25 httpd # drwxr-xr-x 2 root root 4096 Mar 5 18:43 test ssh -i /etc/httpd/privatekey email@example.com # Results in *no* prompt rm -r test cp -R /etc/httpd /etc/test ssh -i /etc/test/privatekey firstname.lastname@example.org # Results in *no* prompt`
I'm sure its just something simple I've overlooked but I'm at a loss.
