I suspect the above error could result from
the use of "ssh-keygen" as opposed to "./ssh-keygen".
Root should not have "." in its PATH setting. Looks that some of your hosts
do have "." in root PATH and others don't.

The next error message looks like one when I try to run
binaries meant for a different OS.
In your case, it is possible that you may have tried to run
binary, meant for Solaris 2.x (  SunOS 5.x ) on Ultra, on
SunOS 4.1.4 (or older?).
When you type the command,
the name of the executable file (mounted via NFS from Solaris host possibly)
to the shell on SunOS 4.1.4. Then, the shell figures out
it is not an object file since the newer ELF format is not known to it,
and tries to run this as shell script, and we get the error.
I have seen this message too many times to figure out
the architecture mimsmatch  immediately :-)
(I used to have Sun, DEC and HP, but now stick to Sun, but we have
SunOS 4.1.4 still running as well as later SunOS 5.x)

If the above was the cause of your problem, you need to create a binary meant for
SunOS 4.1.4 .  That you mention the non-working ones are SparcStation makes
me suspect this scenario.
