When an FTP install fails for some reason (FTP server refusing connections, selected distribution not found on server, etc), most of the time a reboot is needed. Failure to reboot will make it impossible to reconnect to the FTP server (you get DNS errors often, although others have been seen). The DNS server I use and my network connection work fine, if you make sure that you can get into the server. If you let BSD find out that it can't, then you have problems. Fix: Reboot everytime you make a typo. Boot from floppy. Eat lunch. How-To-Repeat: Install BSD. Go into options, and change the distribution to something which doesn't exist. Select your favorate FTP site. Go back into options, change the distribution to one that does exist. It won't work.
Responsible Changed From-To: freebsd-bugs->jkh sysinstall problem.
State Changed From-To: open->closed I absolutely cannot reproduce this - does this happen with any of the recent snaps on current.freebsd.org?
