Re: Convert numbered JPG files to movie
Well, perhaps what you want is MJPEG, which is a packed file with each frame being a JPEG image. Check the MJPEG Wikipedia article and if you google for MJPEG you'll find an MJPEG howto on sourceforge. Now, if I'm not mistaken, an MJPEG file or stream is just a MIME packed stream of JPEG images with content type of multipart/x-mixed-replace. If that is so, you could probably produce an MJPEG file simply by using mpack, and the howtos you may find are for more complicated cases such as converting and MJPEG stream to MPEG. It may not work, but if you succeed in packing/unpacking MJPEG streams with mpack, I would be interested in knowing it because I will be decoding one such stream within a couple of monthes.

I think I may also consider taking a backup of my server setup ... :) Yes, and probably the 8 hour lag was your fault... I was also quite happy at first, they have some problems though - custom dns is a bit broken, sometimes the zone file misteriously vanishes when you change it. They lack some features which, without giving them any more trouble, would make a much better service: like allowing the mix of custom dns and url and email redirection. AFAIK, the perfect registrar is yet to be born... It would be easy to provide better service than them, if you were on that line of business... > > Thanks again, > Martin Not at all, -- Miguel ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

If the problem is keeping the data in memory, I don't think even mod_perl or mod_python will help you. Sugestion #1 - write an apache module; that will be always in memory. I'm not sure if it will be hard to compile. Sugestion #2 - forget about C++ and use mod_mysql or whatever is available for your DBMS. Sugestion #3 - split your web app in two parts: cgi scripts (or apache module) and a server app that keeps data in memory and responds to requests made by cgi scripts. Communication between the two can be made with pipes, sockets, shared memory or whatever you like. Sugestion #4 - load less data from the database; only that which you need to generate output. (For example, for an SQL database, use WITH, HAVING, OFFSET and LIMIT wisely).

Re: Bind as a chaching nameserver
AND make sure that either /etc/resolv.conf doesn't exist or that it contains a single nameserver line like this: nameserver 127.0.0.1 otherwise your local nameserver isn't queried. You see, there's really nothing else to do on a standard installation of freebsd... 1- named_enable="YES" in /etc/rc.conf 2- either delete /etc/resolv.conf or use nameserver 127.0.0.1 The default /etc/namedb/named.conf that comes installed does exactly what you want. -- Miguel Qua, 2006-04-26 às 08:05 +0100, Martin Hepworth escreveu: > Richard > > just set the forwarders to another nameserver in the named.conf and that's > it.. > > this will speed up SA massively. > > -- > martin > > On 4/25/06, Richard Collyer <[EMAIL PROTECTED]> wrote: > > > > Hello, > > > > I've recently been getting a lot of trouble with SpamAssassin performing > > a lot of rDNS lookups which is causing network issues (timeouts etc to > > DNS servers). > > > > I am trying to install BIND (or djbdns) as a simple caching nameserver. > > Just to take some of the load off the networks DNS servers (my ISPs). > > > > However I am having trouble finding a good tutorial to follow. > > > > I've looked at > > http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-dns.html > > but its mainly going on about being a nameserver which is not what I am > > after, wanting to keep it more simple than that. > > > > [EMAIL PROTECTED]:/usr/local/etc] $ named -v > > BIND 9.3.1 > > > > Can anyone suggest me a good tutorial to follow, I've googled but mostly > > they are for debain/redhat and some of the commands and files are > > different. > > > > Cheers > > Richard ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

My hint is very bad (I had a problem once, and assume any problem with gdm is the same). What is the value of the FirstVT option in /usr/X11R6/etc/gdm/gdm.conf?

Secondaries update from your server, initiating a zone transfer when they feel like it. Sending them a notify may also trigger the transfer, but not immediatly. I have a free secondary dns for anjos.strangled.net on rollernet.us, and it only updates from my server at most once a day (just about what I need, but comes close to being useless). > > My questions are - > a) Are my assumptions correct? > b) What would be the best way to explain this to a phone drone? Impossible. If the services you need (secondary dns) are not listed on their website then they won't offer the service either because they don't understand its usefulness or because it's against their interest. > c) Can anyone recommend a good registrar that will be able to set > this up with minimum fuss (and cost)? Check mine, http://www.gandi.net. Not cheap on .com, .net, .org domains, cheap on .info and .name. Anyway, they offer secondary dns and custom dns (if you come to the conclusion that it's best to leave the zone files outside your computer). I'm not entirely satisfied, mainly because they offer email redirection, secondary dns and custom dns, but each of these mutually excludes the other ones. There's also freedns.afraid.org, if you want to put your domain on a good, redundant server, and perhaps only host third level domains on your computer (they allow you to define NS records, and they also offer dynamic dns services). Rollernet.us offers besides secondary dns, backup mx for free. > d) Are there any good reasons not to do it this way (remember, this > is not a mission critical setup, and its main purpose is to tinker) Well, - if you plan to have your main server down for more than a week (default value in SOA record), then your zone will expire, even on secondaries. - if you're on a dynamic IP, then you'll have trouble with most registrars. Perhaps a more flexible option may be having a second level domain on a freedns service (like freedns.afraid.org) and one or more third level domains hosted at your server. But buy a domain, try it, and see what suits you.
