I can't imagine how anyone else could answer that with no information about what the system will be used for. You might find svcs -p useful to associate services with running processes. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup]

Decide what you need and what you don't. . . . You might even visit http://docs.sun.com, download the manuals in PDF format for Solaris 10 System Administration and read them. Hard copy manuals are available if you want to pay for them! If you have the time and the money, Sun Educational Services offers five day courses with titles like Solaris System Administration I, Solaris System Administration II, etc. Five or six years ago they cost about $2,000 each, not counting cost of travel. They may cost more now. You might even want to buy two or three Sun workstations and set up your own home lab. I bought three Ultra 10 workstations so I could have a network to play with. It cost me about $100 each plus CPU and Memory upgrades. The Ultra 5 and Ultra 10 workstation use IDE disks which can frequently be salvaged from old PCs or purchased; an 80 GB drive sells for about $70 US from CDW or PC Connection. The largest IDE disk you can use is 127 GB. You can install a larger disk but you will see only the first 127 GB! Your private lab gives you complete freedom to install and configure, re-install and reconfigure, or to patch or not patch. If you screw it up, you can just re-install.

You can then enable specific services as needed using the svcadm command. For example to enable apache2 (after creating a usable http.conf file) # svcadm enable apache2 -- Mel Gibson isn't known for being faithful to the original source.

I'm not sure why this is such a bizarre question. For Linux, there are several web sites that have lists of all the services and describe what they do. No need to spend hours reading man pages... just look at a list and decide, "I need this one, I don't need this one, I'm not sure about this one". That's all I'm looking for... a list of all Solaris 10 services with maybe a two sentence explanation of what it is. What the heck is "restarter"? "identity"? "coreadm"? Note, I'm not asking the group for info on these particular services, but where I could find out about all of them at a glance. That shouldn't be a tall order. -- * John Oliver http://www.john-oliver.net/ * |
