Description masanari iida 2007-04-11 04:28:19 EDT
Description of problem:
When I configure kdump with scp, I execute "service kdump propagate".
It succesfully propagate key into ~/.ssh/authorized_keys2 file.
But the file permission is not properly changed to 600.
So I failed to start "service kdump start" in the next step.

Version-Release number of selected component (if applicable):

# rpm -qa |grep kexec

How reproducible:
Always when I configure kdump with scp.

Steps to Reproduce:
1. Configure /etc/kdump.conf  as  kdump with scp.
2. Create an account on kdump scp destination box.
3. Execute    # service kdump propagate 

Actual results:
kdump script create ~/.ssh/authorized_keys2 file with permission 664.

# ls -l
total 4
-rw-rw-r--  1 kdump kdump 408 Apr 11 17:00 authorized_keys2

In /var/log/secure, when I start "service kdump start"
Apr 11 16:41:52 abc123 sshd[12083]: Authentication refused: bad ownership or
modes for file /home/kdump/.ssh/authorized_keys2

Expected results:
kdump script create ~/.ssh/authorized_keys2 file with permission 600.
# ls -l
total 4
-rw-------  1 kdump kdump 408 Apr 11 17:03 authorized_keys2

Additional info:

Following line in /etc/init.d/kdump cause the problem.

        cat $KEYFILE | ssh -x $SSH_USER@$SSH_SERVER "mkdir -p ~$SSH_USER/.ssh;
chmod 700 ~$SSH_USER/.ssh;  cat >> ~$SSH_USER/.ssh/authorized_keys2"

        cat $KEYFILE | ssh -x $SSH_USER@$SSH_SERVER "mkdir -p ~$SSH_USER/.ssh;
chmod 700 ~$SSH_USER/.ssh;  cat >> ~$SSH_USER/.ssh/authorized_keys2; chmod 600
