I have some problems with the install of the ssh protocol. I have installed all the packages what I need for that. But when I start the SSH or the Daemon SSHD then I get always the Message "PRNG is not seeded" After that I have download the PRNGD Package too. But I don't know exactly what I have to to that the PRNGD is running perfectly and so I can start the SSH or the SSH-KEYGEN and so on. Who can help me, or better can give me a little instruction what is to do.
Thanks in advance.

I am also trying to set this up and running into the same problem. I have prng running but sshd still give the same "PRNG is not seeded" message. Did you get this resolved?

Thanks,
Gene

Try the following:

1.Install Random Number Generator Patch.
2. Create user sshd
3. Create Key pair.

Thanks

Your problem seems to be created by the patch itself! The Solaris patch 112438-01 should create the /dev/random and /dev/urandom files to be used by the prngd program, but it WON'T create the symbolic links under /dev directory - not even - though the physical devices:
/devices/pseudo/random@0:random
and
/devices/pseudo/random@0:urandom
are being created.

Problem resolution: run the next two commands
1. ln -s /devices/pseudo/random@0:random /dev/random
2. ln -s /devices/pseudo/random@0:urandom /dev/urandom

...and there you go without any problems. Just create your key pairs and run ssh or sshd freely...

You might want to try to install patch 112438-01 from the shell script, which makes rebooting your computer unnecessary after the physical devices being created. Try the following link: http://halplant.com:88/software/Solaris/scripts/setup_random

Hallo Maik,

you have to change the permissions for /devices/pseudo/random@0:urandom and /devices/pseudo/random@0:random
, e.g. chmod 644 ...

Best regards

Hendrik

I'm having this same issue. I've tried creating these sym links, but there is no file called /devices/pseudo/random@0:urandom on my system!

This worked perfectly on Solaris 7, why not on 8?
