samd is the system management daemon. SAM is only a gui on top of samd.

For example, samd keeps record of devices down, removed users etcetra.
You can look at things, by:
strings /etc/sam/reg_da.db
strings /etc/sam/reg_dirs.db
cat /etc/sam/custom/default.tp

Normally, you'll need the following entries:

/etc/inittab:
samd:23456:respawn:/usr/sam/lbin/samd # system mgmt daemon

/etc/services:
samd 3275/tcp # sam daemon

Greetings,

Paula,

Still not what I like to know.
Found that document as well ! But did not bring me any closer.

Ceesjan,

How come sam keeps working if samd is stopped ?

[Ceesjan van Hattum]

Oops, you're right..
Sorry for jumping to conclusions.. just came back from lunch... maybe i forgot to take some coffee first.

I have no samd running on none of my systems (hpux11.00 and 10.20).
The sam-gui and /etc/sam directories are there, but no samd...

As you can find at http://members.tripod.com/rose_swe/cfg/bsp/ulmk460.html and others, the settings are known, but the real function...
I'll continu my search for you.
Sorry again for my false information.
Regards,
Ceesjan

I think it is related to GUI, all my servers are text only and no samd running.

I found this, but am a bit dubious about this explanation.

"Samd(SAM Daemon) maintains a Unix equivalent of the NT SAM and SECURITY database files in a suitably secure format."

It is assigned a port and has an entry in init.
So external connectivity come into it - mind you ???Run sam on remote system??? is a standard option in the text version of SAM so makes sense to have these entries.

Basically if you are not running GUI remove entries in /etc/services and inittab.

Hi Ceesjan,

samd is only running on 11i systems !

Clemmens

My servers are 11.00 so my message about services and inittab - ignore if you are running 11i.

Not correct but I found this :-

SAMD (Single Algorithm Multiple Data)

Paula,

I stopped the samd and started the GUI.
No problem !
Sam is still working fine.

Hi Clemens,

I was given this info from a very wise co-worker. Hope it's the answer you where looking for.

Samd only affects the operation of SAM with respect to the SLVM and DPS services. If samd is disabled, the only consequence is that you cannot use SAM to remotely configure those services. The services can still be configured and used normally outside of SAM if samd is disabled. Let me know if I can be of any further assistance.

In 11.00, SAM used /usr/sam/lbin/samagent for remote operations. (samd uses DCE/rpc)
This daemon was also developed to help enhance SAM in the future and enable multi-system management. Basically, if you have no use of SLVM or DPS,
you can kill it (or if you don't use SAM to manage these).
