And, as I recall, postfix has less file accesses than qmail. (And a LOT less than sendmail.) I love postfix: it's been a pleasure to fiddle with (with a READABLE config) and is amazingly clear code with a wide range of versatility: one of my favorite things is that you can mix and match flat files with db files (usually a hash) with regex's with perl-compatble regexs... Want to have your aliases done "normally" as a hash? Sure.. but you can also add in a pcre file or two, and maybe even a flat file... other than the speed issues for each, postfix doesn't care what sort of 'map' you use. (You can even toss in an ldap or sql map if you want, but I haven't needed that.) The 'sendmail compatible' is overstated. It doesn't read sendmail.cf. It -does- act normally with things like .forward file, and the format of the alias file is the same and that sort of thing. It's actually much easier to get postfix to do Stupid MTA Tricks than it is to do the same with sendmail (did I mention I love pcre's? It's nice to refuse mail from all-numeric 'local parts' in email addresses) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Postfix can receive huge domains. # postconf -e "mydestination = $myhostname, localhost.localdomain, \ hash:/etc/postfix/virtual" You list your virtual domains in /etc/postfix/virtual file.

Hello Duane On 27 Mar 2001, at 21:58, Duane Powers wrote: > I don't know if anyone has the details on redhat's kickstart > program, and whether that is something that could be ported to > debian... Any suggestions? At the moment we do the following: - base install (3 floppies + base.tgz from nfs drive). - break the installation when "dselect" starts - download a "configs.tgz" from the network. This contains customized versions of debian "config" files in /etc as well as other utilities in /usr/local/ and /var/www/. This configures /etc/apt/sources etc. It also contains a file "/etc/deblist" which was generated using "atp-get --set-selections". - run apt --get-selections < /etc/deblist - run apt-get --deselect-update - manually edit /etc/... to suite the particular install. This is flexible, when we change something on the network, we change in the master "configs.tgz" and all subsequent installs get it. The process is not broken when there is an upstream update - because of debian policy for "configuration" files. We have a script which backs up each machine and creates a personalized "config.tgz" file. If we have to reload a machine, we just use that one instead. (It will get upgraded to the latest "stable" stuff during the re-install process.) The problems: "apt-get --deslect-upgrade" is painfully slow - particularly on slow hardware. And you have to sit and watch and answer "y/n" stuff 'till it is finished. (Can't wait for debconf to be working on a useful level). The personalisation of the config files is slow. I think we could do with a script which runs after the config.tgz has been extracted and asks things like domain names and user names. I tried using a customized "base.tgz" that installed everything in one go. But it was too inflexible and introduced too many bugs, so we went back to the old procedure as outlined above.

Re: Streaming Video
I have some experience doing this, so here goes: 1.) you need some kind of encoding equipment. This will depend on the quality of video you want to stream, the format, and the bandwidth available. For example, if you want to do real-time streaming, you need HARDWARE encoding. Software encoding is just not fast enough for real-time streaming. A word to the wise...real-time capture-streaming is EXPENSIVE! As far as hardware suggestions go, I recommend either the Minerva box (a network appliance), or the Optibase cards. 2.) You need to pick a streaming media server (software). The realmedia streamer is free for demo, but the quality of realmedia is somewhat lacking, as I'm sure you know. This may however, be a viable option depending on bandwidth. If you want to stream mpeg or mpeg2, you are going to shell out some major cash for the software. 3.) Storage will be important. You will need a bit of storage if you want to archive anything. Even if you don't want to archive, encoding-streaming will take up a chunk of space on a fast disk set as temporary files are created dynamically. This being said, you are also going to have to have a dedicated server to stream. The system requirements for a streaming server are a lot higher than you might expect. The streaming server will choke, wheeze, gag, and otherwise be unhappy if you are doing ANYTHING else on it. Yes, this is regardless of the OS. 4.) I recommend you contact SICORP. I worked for them previously as a tech, and they do know what they are talking about. You want to contact JD.

Re: "kickstart" for debian needed
Hello Duane On 27 Mar 2001, at 21:58, Duane Powers wrote: > I don't know if anyone has the details on redhat's kickstart > program, and whether that is something that could be ported to > debian... Any suggestions? At the moment we do the following: - base install (3 floppies + base.tgz from nfs drive). - break the installation when "dselect" starts - download a "configs.tgz" from the network. This contains customized versions of debian "config" files in /etc as well as other utilities in /usr/local/ and /var/www/. This configures /etc/apt/sources etc. It also contains a file "/etc/deblist" which was generated using "atp-get --set-selections". - run apt --get-selections < /etc/deblist - run apt-get --deselect-update - manually edit /etc/... to suite the particular install. This is flexible, when we change something on the network, we change in the master "configs.tgz" and all subsequent installs get it. The process is not broken when there is an upstream update - because of debian policy for "configuration" files. We have a script which backs up each machine and creates a personalized "config.tgz" file. If we have to reload a machine, we just use that one instead. (It will get upgraded to the latest "stable" stuff during the re-install process.) The problems: "apt-get --deslect-upgrade" is painfully slow - particularly on slow hardware. And you have to sit and watch and answer "y/n" stuff 'till it is finished. (Can't wait for debconf to be working on a useful level). The personalisation of the config files is slow. I think we could do with a script which runs after the config.tgz has been extracted and asks things like domain names and user names. I tried using a customized "base.tgz" that installed everything in one go. But it was too inflexible and introduced too many bugs, so we went back to the old procedure as outlined above.

Re: Streaming Video
I have some experience doing this, so here goes: 1.) you need some kind of encoding equipment. This will depend on the quality of video you want to stream, the format, and the bandwidth available. For example, if you want to do real-time streaming, you need HARDWARE encoding. Software encoding is just not fast enough for real-time streaming. A word to the wise...real-time capture-streaming is EXPENSIVE! As far as hardware suggestions go, I recommend either the Minerva box (a network appliance), or the Optibase cards. 2.) You need to pick a streaming media server (software). The realmedia streamer is free for demo, but the quality of realmedia is somewhat lacking, as I'm sure you know. This may however, be a viable option depending on bandwidth. If you want to stream mpeg or mpeg2, you are going to shell out some major cash for the software. 3.) Storage will be important. You will need a bit of storage if you want to archive anything. Even if you don't want to archive, encoding-streaming will take up a chunk of space on a fast disk set as temporary files are created dynamically. This being said, you are also going to have to have a dedicated server to stream. The system requirements for a streaming server are a lot higher than you might expect. The streaming server will choke, wheeze, gag, and otherwise be unhappy if you are doing ANYTHING else on it. Yes, this is regardless of the OS. 4.) I recommend you contact SICORP. I worked for them previously as a tech, and they do know what they are talking about. You want to contact JD.

Does anyone have a suggestions about streaming video. I have a Town as a client and they are asking about streaming their local cable access channel over the net. I'm guessing I can grab the video feed off of the cable through a TV card in the Web server but then what? All hardware/software suggestion are welcome.
