The problem was with the hostname I had given my PC - being a seasoned Windows user/developer on a Linux learning curve I gave my pc a hostname in the format "aaa" (as you would in Windows
) however OO expects it to be in the format "aaa.bbb.ccc", i.e. vector.linux.net.
Changing the hostname into the required format results in OO starting with no delay.
My experience does not indicate that a hostname in the format aaa.bbb.ccc is required by OOo or anything else. I have no delay in opening OOo and my computers are named as follows:
The domain name is not actually OURDOMAIN but it's a single word in all caps. The computer names and domain name are the same in Windows. I gave the computers their names and also made up the domain name, as we don't really have a domain, just what Windows calls a workgroup.
Perhaps I'm missing the point or some detail. But I've been naming computers as aaa.BBB for years in Linux and have no problems. I use fixed IP addresses assigned by me for the computers. The router gets a DHCP address from the ISP. It is of no relevance for purposes of the home network. I use a DNS server address given by my ISP.
I am absolutely NOT suggesting you change anything that's working. I'm just questioning whether an aaa.bbb.ccc format is *necessary* and if so, why has my aaa.BBB format worked for years?
