ssh error message

ssh error message

[Peter]

Hi,

when booting I get the following message:

  starting ssh: execvp: No such file or directory  [failed]

I uninstalled openssh, reinstalled, still I get the same message.

How do I correct this?

Thanks & regards

Can you post the portion of your log entries which show some details?  You may have to turn on debugging features to get the output.

In setup-system-services sshd is enabled.

There is a man age for execvp and execve which to understand is beyond my 
training.

In man execve I find under ERRORS:

              does not exist, or a shared library needed for file
              or interpreter cannot be found.

How do I find that out which of these might be the cause of the error?

Do you have the file:

/etc/ssh/sshd_config?

Please try running sshd from the command prompt.

There is no sshd to run; I mean in one of the (s)bin directories.

Aha! sshd.  I thought it was odd to try to run ssh as a daemon.

try "file /usr/sbin/sshd"
"ldd /usr/sbin/sshd" for details on shared library problems;
see if user 0 can run it from the command line:
"/usr/sbin/sshd"

I am running RH72. I can't find a file called sshd in any of the CDs there is 
only openssh.

ldd: /usr/sbin/sshd: No such file or directory.

In none of the /bin /sbin directories is there any sshd file and I do not know 
in which  program it is hidden in any of the install CDs of RH7.2.

These programs are installed:
openssh-3.1p1-3
openssh-askpass-3.1p1-3
openssh-askpass-gnome-3.1p1-3
openssh-clients-3.1p1-3

Re: ssh error message

[Ray Olszewski]

Peter -- if ldd cannot find sshd at its normal install location, then 
either you did not install it (no matter what you think you did) or you 
installed it to a non-standard location.

To check the second possibility, see if (as root) "find / -name sshd" 
returns anything. If it does, then you can probably just creater a symlink 
in /usr/sbin/  to the real location.

As to the packages (what you call "programs") you say are installed ... 
that version of OpenSSH is the current one. The Debian equivalent, "ssh", 
installs both server (sshd) and client (ssh). From the assortment of 
package names you list, I'd *guess* that RH has the server and client 
separated.

So if "find" does not turn it up for you, I'd try re-installing the 
openssh-3.1p1-3 package (it's likely to be the server, since another is 
middle-named "clients")  and seeing if that helps.

RedHat do split it out into client and server

The server rpm is openssh-server.

As Ray pointed out above, you have not installed the ssh daemon. From the above list, one can fairly conclude 

that only the ssh clients are installed on your system. Therefore, you should install the daemon, which resides

in the openssh-server-3.1p1-3.XXXX.rpm package (where XXX may be i386, 
i486, etc). This rpm is probably on the 2nd installtion CD. Hope that helps.

Not really. At least I didn't, either then or now.

I was attempting to distinguish an actual program, such as sshd (that is, 
either an executable binary or source code that can be either compiled or 
interpreted), from a package that contained that program, maybe an 
associated init script, a man page and other documentation, possibly sample 
config files, and whatever else the packager thought worth including(or the 
packaging system requires).

The distinction was meaningful back in mainframe days, and it remains 
meaningful today. Packages often contain programs, but they are not the 
same thing as programs.

In the context of troubleshooting your problem, drawing the distinction was 
cogent, since the problem was that you were mistaken about which package 
actually contained the program you wanted to run.
