SSH

[Cordell Robinson]

How much resource space will SSH use while running on an HPUX 10.2 and/or 11.0 workstation?

[Steven E. Protter · Accepted solution]

Disk Resources 20-30 Megabytes depending on what version you use. If you are running 11.00 you can download depots that install out to at most 40 Meg.

I'm running a massive scp file transfer right now and the process is ising 4 Megabytes of memory.

ssh is using 5 Megabytes of memory.

Thats really not much. This is a server. You are dealing with a workstation which isn't likely to have a lot of simultaneous connections.

the memory resident portion is even lower.

780 Kb for ssh
304 Kb for scp

Pretty efficient.

Sorry about the multi part post.

I should point out that the initial handshaking between the 10.2 & 11.0 O/S's will be SLOW: 20-30 seconds (or more depending on what hardware you're using). This is because the kernel has to generate and authenticate a random number. This has nothing to do with CPU resources (a temporary hit perhaps).
HPUX 11i has a /dev/random device that dramtically speeds up this process. It will handshake and authenticate in less than 10 seconds on even a moderately fast machine.

If you can: upgrade to 11i. Its worth the time and effort.

I've also attached my (now famous) document demonstrating how to use Secure Shell so that there will be no password challenge.
