Re: [asterisk-users] OT - How to organize TFTP root directory ?
2009/10/24 Warren Selby wcse...@selbytech.com What I do is run virtual interfaces on one box, and run multiple instances of atftpd inside xinetd, Great idea ! I didn't know it could be possible to run several instances of xinetd, each binded to a specific IP address. Is this specific to xinetd or does openbsd-inetd also support this feature ? Anyway, I'll check this in openbsd-inetd doc myself and (hopefully) report my findings here.

Anyway, I'll check this in openbsd-inetd doc myself and (hopefully) report my findings here. xinetd will let you do multiple bindings of a single port, with a single instance of xinetd running. You would define two service entries in the config file, with the same service name, different ids (e.g. tftp1 and tftp2), and different bind addresses (one for each interface). Each service entry would then run a different server program, or the same server program with different server_args. As far as I know, standard BSD (and Linux) inetd doesn't have this capability. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

You can also name the Ethernet interfaces to match: sudo ifconfig eth0:cisco w.x.y.z up Might as well make it obvious for the next guy. A good work-around, but I still like the idea of adding an execute configuration tool feature to atftpd. -- Thanks in advance, - Steve Edwards sedwa...@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

This helps, because it is fairly easy to write a script which dynamically generates the configuration. Right. Using TFTP has the obvious problem of placing all the configurations of the phones inthe open. Anybody can just go and grab them. (Hmmm... I wonder what it would take to do a brute-force scan on the range of all the MAC addresses used by IP phones) It is slow and unextendible. HTTP allow you to provide different content by User-Agent, by Host (name-based virtual hosting), and many other. Just in case you want to provide dynamic content over TFTP, be sure to cache it somewhere, as the dumb TFTP client can request any block of data from the middle of a file. It's no like a simple HTTP client takes that much ammount of code. Etherboot (http://etherboot.org/ ) has had an implementation of PXE over HTTP for quite some time. They were operating under the strict limitations of 64kB code size limit (and weren't getting anywhere near that, unless you built it with all the card drivers). TFTP should just die. -- Tzafrir Cohen icq#16849755 jabber:tzafrir.co...@xorcom.com +972-50-7952406 mailto:tzafrir.co...@xorcom.com http://www.xorcom.com iax:gu...@local.xorcom.com/tzafrir ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Re: [asterisk-users] OT - How to organize TFTP root directory ?
What I do is run virtual interfaces on one box, and run multiple instances of atftpd inside xinetd, each one bound to a different IP and a different root directory. Thus, my file structure looks like this - /home/phones/ /home/phones/cisco/ /home/phones/cisco/7960 (root directory for one of the atftpd instances) /home/phones/cisco/7961 (root directory for another atftpd instance) Then, with a little dhcpd.conf magic, you can easily point different sets of phones to different tftp servers, using pools that match on key Product ID (I think) strings. --Warren Selby On Fri, Oct 23, 2009 at 8:54 AM, Steve Edwards asterisk@sedwards.comwrote: Steve Edwards asterisk@sedwards.com writes: atftpd can do PCRE substitutions to transform a requested file name into something else.

This makes this TFTP root directory a bit messy. What are the best practices or tricks to manage this TFTP root directory ? I was thinking of either : 1. building a dedicated source TFTP tree in which files are cleanly organized (vendor/models:...) which would be synchronized (one way ? two ways ?) with the official TFTP tree (that would be then, collapsed to a single directory) 2. tune DHCP/TFTP server config so that each phone would retrieve its config files from a vendor-dedicated subdirectory. I don't have a clue about solution 2. Is it even possible ? Solution doesn't look very encouraging as it might be difficult to keep trees in sync. #2 might be possible, but there's a lot of depends on factors. The ISC dhcpd often packaged in linux distributions has the ability to specify different dhcp options to different pools of addresses. You can then assign clients to pools based on a substring match of their mac address. This then requires that the client (phone) will use the URL specified in dhcp option 66. With all this put together you can assign each brand of phone to its own pool/options where the options point it to a URL containing the firmware for that brand of phone. I do this with my polycom phones and it works well. Don't know if it works with other brands of phones. -Dave ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I think assigning a given address or an address pool to certain phones is quite easy. The trouble is to somehow forward every TFTP request coming from this address to a given subdirectory. For example, Thomson ST2030S phones would query a kind of bootfile (whose name can be changed with ISC DHCP server options) but it would later query another config file which (apparently) must reside on TFTP root. Sometimes, I wondered if I should have several logical IP addresses for my physical TFTP server so that I could forward each TFTP request to appropriate subdirectory : if TFTP request is received in address1, then root directory is /srv/tftp/dir1 and so on ... -- Jared Smith Training Manager Digium, Inc. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
