Description manikandan 2006-03-03 03:20:50 AEDT
Hi,

I have SSH installed in a HP-UX system.
Its version is 
SOE-openssh-3.7.1p2-pwexp26, SSH protocols 1.5/2.0, OpenSSL 0.9.7d 17 Mar 2004.

Now when i try to use sftp from other systems  to HP -UX where ssh is installed it is not working fine as excepted.

In brief i will mention the steps i followed.

1) Create a ssh-agent (client)by giving 
    eval `ssh-agent`
    And get its PID.

2)Then set the environment variables as
    --  export SSH_AGENT_PID=<ssh-agent_PID>>
    Then go to âcd /tmpâ and then do a âls -lrtâ to find some directory which is of name âssh-___â and then get into that ssh-____ directory ⦠you will have some file with the name âagent.xxxxxâ
    -- export SSH_AUTH_SOCK=<complete path as you find from above pwd command >

3)Then create the ssh keys by giving
#ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (//.ssh/id_rsa): 
//.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in //.ssh/id_rsa.
Your public key has been saved in //.ssh/id_rsa.pub.
The key fingerprint is:
8d:30:30:54:63:76:ff:bb:46:f7:55:2f:fb:7a:f9:2d root@wcary2qw

There enter the passphrase of some 8 characters.

4)Then add the keys to ssh-agent by giving
#ssh-add 
Enter passphrase for //.ssh/id_rsa: 
Identity added: //.ssh/id_rsa (//.ssh/id_rsa)
#
Enter the passphrase typed before.

4)Copy the public key(id_rsa.pub) and put the public key in the HP -UX corresponding user's home directory under .ssh directory in authorized_keys file.
  Suppose if we are giving 
    #sftp xxxx@47.128.213.56
   Then go /home/xxxx/.ssh 
   #touch authorized_keys
   #chmod 777 authorized_keys 
  Paste the public key inside this file.

5)Now when you do sftp xxxx@47.128.213.56 it will not ask for password it will directly go to sftp prompt
    #sftp xxxx@47.128.213.56
    sftp>

This as excepted.The same scenario is working for all os but for HP -UX it is not working.

So could anyone throw some lights on this issue.

Debug mode details obtained when tried sftp to HP-UX system

That looks like the HP-supplied package (and an old version at that).  Can you reproduce your problem with the vanilla source from http://openssh.com?
 
>    #touch authorized_keys
>    #chmod 777 authorized_keys 

This is probably the source of your problem and is a really bad idea.  Your authorized keys files should not be writeable by anyone other than the owner (mode 755 or better yet 700).

You can disable this check with the StrictModes sshd_config option but that's also a bad idea; better you fix your file permissions.

This is clearly a user misconfiguration.

Change all RESOLVED bug to CLOSED with the exception of the ones fixed post-4.4.
