Hello I have Secure Shell on my servers. I have the following problem:

1)Each time the ssh command is launched the following is displayed:
Couldn't connect to PRNGD socket "/var/run/egd-pool": No such file or directory The ssh connection is working but we do not want the error message. Although the Strong Random Number Generator was installed, I do not have /dev/random nor /dev/urandom

2) I can ssh as stated above but cannot sftp. It just hangs with Couldn't connect to PRNGD socket "/var/run/egd-pool": No such file or directory

How can I resolve this? All replies are appreciated.

Are you sure it is installed ?

swlist -l fileset|grep -i random

Yes. See my output below:

You can try to make the device files with mknod, should look like this.
1580 cr--r--r-- 1 bin bin 78 0x000000 Aug 11 2007 /dev/random
1597 cr--r--r-- 1 bin bin 78 0x000001 Aug 11 2007 /dev/urandom

Or, force a reinstall of the software and double check the swinstall logs to see if there was any error.
