UNIX for Dummies Questions & Answers

Hi,

I have a generic id say "abc". In a client i logged into using this generic id and generated the key for autologin to do ssh to a server.

I have kept the key in authorized_keys file in the server under the home directory of this generic id. (/u/abc/.ssh/authorized_keys)

when i do ssh to server from this client it is not logging in automatically and asking me to enter the password.

How to fix it. i have other generic ids for which auto login is working fine. only for this partcular id i am facing the problem.

what could be the issue, Please suggest. Thanks.

Hi,

can you please post the command you enter to start the ssh session and the output of the subsequent login failure? (please use verbose output from ssh with the -vvv switch)

thanx
fra

options to note:
1. is /u/abc/ the right home directory for abc?
2. maybe its about time you create a new id_rsa.pub adn copy the contents anew to your server's authorized_keys

goodluck!

Hi,

As i already mentioned, it is working fine for other generic ids. so it is not time which is the fact for the issue.

i ran the command ssh-keygen -t rsa and it created a file named id_rsa.pub which contains the value that i copied it to authorized_keys file in /u/abc in the server.

it is not giving any error when it tried to login automatically from client, just asking password to enter.

also i found something else when i dig more,
i logged in to server directly by this way

Code:

 
ssh rbalaj16@server1
pasword: (here i am entering the password)
./sesu - abc
password: (same password again i enter here)

when it goes inside, it is not setting the PATH variable which wil be set using the procedure mentioned in .login or .profile file under /u/abc. even whoami command also not working. is this the one making issue when i try to autologin?
but for other generic ids PATH set is working fine.

Hi,

regarding getting rid of the password request at login time, try to explicitly specify the full path to the id_rsa (the local *private* key) on your local host with the -i switch of ssh command and let's see if passwordless login works.

Please also use the -vvv switch so that we can see the full ssh session debug messages.

Then we can nail down the other issues.

see ya soon

Hi,

Auto login is working fine now.

i googled with error after i enable the verbose mode -v
found a forum SSH Key Failure on One Account - The macosxhints Forums
which discussed on the same topic.

it worked out after i change the permission as below.

Code:

 
chmod 700 /u/abc/.ssh/authorized_keys
chmod 600 /u/abc/.ssh

Thanks for your help and suggestions.

Hi,

can you please help me to fix the another issue i mentioned in this thread.

when i get into a server as genric id say "abc". it is not setting PATH variable, even whoami also failing.

what changes i have to make in .login or .profile file.

Hi,

can you please try to check if .bashrc in the user's remote home directory is exsistent and contains a PATH definition? If not, create/edit the .bashrc file so that there is a PATH definition in there; finally source .bashrc in your users' remote homedir .bash_profile, i.e.:

Code:

 source ~/.bashrc

let us know how it goes
see ya
