Since I only use emacs to edit files, I can do without whatever internet services it is trying to access. Can anyone suggest how to fix this problem?

At home it is a second or two. DNS on your laptop is broken: Emacs is trying to resolve something, probably the FQDN to an address, or the address to an FQDN, that takes that long to time-out. This would be equally true of any other service that tried the same translation, but you don't notice because little other desktop class software does perform that check. At a guess.

Thanks Daniel, I know stuff will break when I go outside the limits of the LAN, but as I said, all I use emacs for is to edit files. My problem is, how do I turn off whatever it is trying to do (since I won't be needing the results of its doings anyway)? As it happens, I was trying to edit the files to get the network going elsewhere, and the 2 minute delay each time was really funny, in an annoying fashion. -- Ron House Building Peace: http://peacelegacy.org Australian Birds: http://wingedhearts.org Principle of Goodness academic site: http://principleofgoodness.net ^ permalink raw reply [flat|nested] 10+ messages in thread

Ah, sorry, I wasn't clear: this does not *have* to break when you are outside your LAN. My laptop doesn't, for example, which is good. > My problem is, how do I turn off whatever it is trying to do (since I won't > be needing the results of its doings anyway)? Some of these things happen inside glibc, I am afraid, so the answer is typically "with difficulty". I don't know specifically what in Emacs is triggering the behaviour, though. I would suggest ensuring that your host has an entry in /etc/hosts for the hostname you use, though, which should reduce the problem. Alternately, you could tune down the DNS lookup time. > As it happens, I was trying to edit the files to get the network going > elsewhere, and the 2 minute delay each time was really funny, in an annoying > fashion.

I remember (some 7-10 years ago) that emacs would simply not start with a broken network setup I dont remember what the correction was (something to do with hosts) but what I do remember was something like this: emacs would refuse to start if the ethernet cable was unplugged. And I was (more or less as you describe): What the hell does emacs have to do with the net side of things?! > > > As it happens, I was trying to edit the files to get the network going > > elsewhere, and the 2 minute delay each time was really funny, in an annoying > > fashion. > > All die.

It needs a unique system name to do proper file locking when editing possibly networked files, and to be able to reliably work with emacsclient. That's well within the "all I use emacs for is to edit files" department. -- David Kastrup ^ permalink raw reply [flat|nested] 10+ messages in thread

Actually I think what it tries to do, is to find the FQDN of the machine it's running on. https://bugzilla.redhat.com/show_bug.cgi?id=216311 http://groups.google.com/group/comp.emacs/browse_thread/thread/783fe03168a5c168/640f9279be617a10 The workaround, according to the above URLs), is to put the FQDN of the laptop into its hosts-file.

A good to start to identify this package is to check what it's trying to connect to. Maybe you can try to start emacs using 'strace', and see what it's waiting for? What happens if you bring down the network interface? Good luck, Dirk. -- Dirk-Jan C.

From etc/PROBLEMS: *** Emacs startup on GNU/Linux systems (and possibly other systems) is slow. This can happen if the system is misconfigured and Emacs can't get the full qualified domain name, FQDN. You should have your FQDN in the /etc/hosts file, something like this: 127.0.0.1 localhost 129.187.137.82 nuc04.t30.physik.tu-muenchen.de nuc04 The way to set this up may vary on non-GNU systems. ^ permalink raw reply [flat|nested] 10+ messages in thread
