Permission denied (publickey).

Hi Everyone,

This site is really impressive lot of useful info. I am a new user (Just registered ;D). I have started using mac from few days. I am struck on some problem if some one had encountered/aware of this please help

I am trying to install a database. From terminal I have logged in as root user and have added the hostname in the /etc/hostconfig file. After which I tried connecting through ssh to the user "Viswanath" I got the below error

sh-3.2# hostname
Viswanath

sh-3.2# ssh Viswanath@Viswanath
Permission denied (publickey).

sh-3.2# ping Viswanath
PING Viswanath (216.255.187.213): 56 data bytes
^Z
[2]+ Stopped(SIGTSTP) ping Viswanath

sh-3.2# ssh [email protected]
Permission denied (publickey).

In the database which I am installing there is a step which I am supposed to execute during which it started asking me (Pls find the log below) for the password continuously even after entering the password. Then to check if I could login to my user using ssh I followed the above process even that didn't work

sh-3.2# gpssh-exkeys -h Viswanath

I also tried creating a new user from the system preferences--> accounts and then tried connecting through ssh but all my tries went in vain.

sh-3.2# ssh gpadmin@Viswanath
Permission denied (publickey).

If some one is aware of the solution please help.

Thanks & regards

Hi All,

The issue is solved. Need to change the permissions for ssh folder also /etc/hosts file need you add
127.0.0.1 hostname...
