[[!meta title="Sysadmin bootstrap - seek for information"]]
|
|
|
|
After [[having setup the sysadmin console|sysadmin-bootstrap-1]],
|
|
it's now time to find out
|
|
|
|
Where to start?
|
|
|
|
## Background
|
|
|
|
When I start a new job somewhere, the biggest challenge in the beginning
|
|
is to find out, what to do, where, when and how. In most companies this
|
|
becomes clear after a few days. In ETH, it's a bit different: There are
|
|
many internal service providers, each with very different focus. To find out
|
|
which are the machines I have to take care of, where they are located
|
|
and which services are running on them took me about a year.
|
|
|
|
|
|
## Step one: My bosses and the local sysadmins
|
|
|
|
The ones who hired me should best know, what needs to be done.
|
|
After getting some basic information, the next
|
|
information centre here in ETH is the ISG, the
|
|
"IT Service Group", which takes care of general IT issues
|
|
in the department. In my case this is the the
|
|
[isginf](http://www.isg.inf.ethz.ch/).
|
|
|
|
### Your local ISG
|
|
|
|
So, what's about that ISG thingy? Why is it needed if I am hired
|
|
as a sysadmin? Aren't we competing against each other? The simple
|
|
answer is: **No.** While the ISG is also doing sysadmin related
|
|
stuff, their focus is on a broader view than the one of a dedicated
|
|
sysadmin. To quote from
|
|
[their site](http://www.isg.inf.ethz.ch/AboutUs):
|
|
|
|
...purchasing and repairing hardware....
|
|
...operating various central services...
|
|
...administration of several hundreds of workstations...
|
|
...allow the users...to concentrate on their main tasks...
|
|
|
|
So as a sysadmin, maintaining hundreds of server and cluster machines,
|
|
focussing on the groups demands, the sysadmin is mostly working in
|
|
a different area. On the other hand, a sysadmin can have the ISG
|
|
maintain stuff in the group, which they can do good
|
|
and the sysadmin probably does not want to do (like Windows workstations).
|
|
|
|
|
|
## Step two: Retrieve information from newly know sources
|
|
|
|
After the initial contact with the local folks, I'm ready to
|
|
dig into other sources I am know aware of. In this case:
|
|
|
|
* [The Systems Group wiki](https://wiki.systems.ethz.ch/)
|
|
* [The Sysadmin wiki](https://trac.systems.inf.ethz.ch/trac/systems/ns/)
|
|
* [/sans/: sysadmins home](http://sans.ethz.ch/)
|
|
* [Informatikdienste](https://www1.ethz.ch/id/services/a_z)
|
|
|
|
### Systems Group in detail
|
|
|
|
Most of the information related to the sysadmin job for the Systems
|
|
Group can be found in the wiki. Though the wiki is probably always
|
|
a little bit behind the reality, it is heavily used and gives pointers
|
|
to the right places.
|
|
|
|
### /sans/: Sysadmins home
|
|
|
|
This is still a pretty young project, but unique at ETH: It is a
|
|
regular sysadmin meeting and information exchange, without the formal
|
|
stuff or the the borders of departements. You may find a lot of
|
|
sysadmin related information directly on the website or find out more
|
|
in one of the meetings.
|
|
|
|
### ID: Informatikdienste
|
|
|
|
The ID are offering basic IT services for the whole ETH. Most of the
|
|
network stuff and things like the [Blog service](http://blogs.ethz.ch/)
|
|
is made by them. Although as a sysadmin you're mostly just using their
|
|
services without interacting with the people behind them, it's a good thought
|
|
to get in contact with them: In case the network is not working anymore,
|
|
they are the right ones to ask for help.
|
|
|
|
There's a "little" trap though: The ID combine a lot of "smaller"
|
|
departements and one has to find the right one for the right problem.
|
|
|
|
|
|
## Step three: Not offering your own services
|
|
|
|
While after some time a sysadmin will find out that a particular service
|
|
is missing in the group, it is probably worth **not** to offer it yourself:
|
|
Although one may get the impression that this particular service is not
|
|
available at ETH, you may almost always be wrong:
|
|
|
|
Almost every service is already being provided somewhere at ETH.
|
|
|
|
## Step four: Offering your own services
|
|
|
|
After one has tried out the various services, you may still be unsatisfied:
|
|
Either because the service is not being offered they way you require or it
|
|
takes you a lot of time and energy to use it. While it may be worth and useful
|
|
to run your own service, always triple check step three!
