Hi all

I received " prngd[1759]: write() in socket_write() failed: Broken pipe " error in syslog ..

Is that will create any problem if it is please guide me how to resolve it.

Hello,

Chasing up on prngd as a possible root cause I think is quite worthwhile, and you suggestion about installing /dev/random is something quite good to pursue too.

I recommend you install the following application to avoid that error.:

Probably that software will fix that issue, actually is a common issue when using ssh.

Best regards,

It looks as though a reader process (possibly an ssh client) terminated while trying to read a stream of random number. Do a:
UNIX95=1 ps -C prngd -o comm,pid
to see the the PRNG daemon is still running. If so, you are fine. If not,
cd /sbin/init.d
./prngd.rc stop
./prngd.rc start

I've tested that in other servers, that a occurence of the client-sessions, you can fix that temporaly by a reboot, but it will returns.

prngd[2168]: write() in socket_write() failed: Broken pipe.

Fix.:
Install /dev/random

Have fun!!!
