Ordinarily (in a perfect world) I would totally agree with those comments, but alas, I don't live in a perfect world. So I've found that because (in my case) the addressing, etc. is controlled by another group, I've found it easier to get them to allocate an address (from their pool) and have it fed to my machine via DHCP (it sadly seems that the world has almost forgotten that you can assign things statically!) Then I can also allow them to feed me the correct domain and DNS resovler information, etc. (so that I can behave and operate nicely within their network). I have them feed me this info, because otherwise, when _they_ change the network, I'd never know... until _after_ I found out something was broken. Having said that... I still had to implement the address as static and I had to turn on my own 'bind' for DNS resolution, etc. because a lot of the information they provided by DHCP was still incorrect. But that was the idea. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
