Re: [RDD] Can create, overwrite, but can't delete carts/cuts in rdlibrary/rdimport
Hi, I normally list all machines as their IP unless its just a standalone in which case I think its usually down as 127.0.1.1. Obviously the machine host name doesn't change. It seems odd that it will do everything except delete. I'm pretty sure since Riv 2, it has used the /var/www/rd-bin/ directory to run the rd cgi script for cart manipulation. Is it possible this script is not complete in some way or that the backup host is trying to use apache from another machine rather than its own local one? The setting for this is inside rdadmin - edit host: HTTP Xport: localhost Core Audio Engine: localhost Wayne Merricks The Voice Asia On 19/08/13 17:56, Jim Stewart wrote: Hmm. You might be on to something: Yes it does seem to have the correct IP and hostname, but: The backup is on the inside of an additional NAT router. The history of this is that the ONAIR machine was also inside of this at one time, but because this router (which also provides a VPN for other purposes at our company), has not be the most robust and reliable, I moved the ONAIR machine to the outside of it. Our new ON-AIR (ON-AIR2) is also on the outside and works fine too. So the backup seems to be able to reach the ON-AIR machines just fine as it is outbound traffic, but there could be issues with the ONAIR machine reaching the backup through the NAT. I think I have MySQL configured accept connections from both LANS (both just private IP LANS), but I may need to double check that. I can swing the IP address for the database location on the backup back and forth between the On-Air and the local database just fine. Is there any other kinds of traffic I need to verify can happen between the two machines?I also think this router might provide a symmetric NAT, or something like that as our Telos-One CODEC won't work through it (even with proper ports forwarded) either. The only question about this is why the backup also doesn't seem to run in standalone mode (only looking at itself for everything). In review rdadmin shows the backup as hostname of pas0, and an IP address of 192.168.0.11 (but just tried 127.0.0.1 too). Inside the NAT there is a Windows server providing DNS resolution of pas0 but not on the outside. The on-air machine has a hostname of On-Air but just the loopback 127.0.0.1 for the IP address (its real address is 192.168.4.10), is this a problem? Also of note is that the backup server is an older installation that has been upgraded in-place through a couple of major debian versions, in case there might be some left over cruft their. Can you propose some additional tests I can perform to see if we are proceeding down the right path? Thanks so much for your time!

Eventually I plan on writing a little blog/article about my experiences and configuration that should be helpful to others but want to learn a little more about Rivendell and tweak my setup a little more before I do. I currently have the core system working, with Jack audio on a Presounus 1818VSL USB multichannel sound device, running three darkice streams (Transmitter, Public, Preview/Production) from Jack with some processing done by jack-rack inserted in the public stream. I have RDAIRPLAY doing all kinds of routing changes and other things via macro carts fired from either a log, or hot buttons (that sometimes call external shell scripts), I have RDCATCH grabbing and importing various elements on a daily basis. Then I have all this fully remote accessible via both VNC and remote X (usually tunneled through SSH) for our operators to use on their Windows desktops and smart-phones. We play locally stored music interrupted by live remotes and sporting events (with cue, talkback, and mix-minus foldback) from either Skype, or a Telos-one CODEC, or a Plain Old Telephone (POTS) interfaced to the Presounus sound device (Can I use LiveWire on the Telos CODEC directly to the computer?). We rebroadcast our college games (with their permission) via their webcast that has 25/35hz subaudible automation tones (currently using a borrowed hardware tone decoder, does anyone know of a good linux/Jack-compatible software solution? The NCH-audio + Wine + Alsa_In solution seems too messy to me) Did I mention this was all on one computer and I haven't even needed to install a traditional broadcast audio console yet? My main remaining task is to get three rivendell systems working in a hot-backup/fail-over + cold-standby arrangement where two systems are typically powered on at a time (main and backup-server), and this backup-server gets constantly updated from the main system via rsync (have that working now), and have the database configured for master/slave redundancy (not working yet) in a way where the backup can run fully stand-alone with the master on-air system down. Then I want a third computer (already have it running) that would normally be powered off, but can be powered on and then synced from the backup-server so that it could become a new ONAIR machine. (our backup-server is a headless thing that is located in an awkward location and normally used for other purposes so not to be appropriate as a permanent replacement for ONAIR). Our ONAIR machines come from a pile of older Pentium-4 semi-server class machines that were discarded and given to us by an associate company. So our plan is to simply run them into the ground on our radio station, but with the security of having a good system of fail-overs and backup

Since the users section resides outside the Hosts section in rdadmin, I kind of assumed it was global for all machines in the database. In any case, the user names and permissions seem to match when running rdadmin from each machine, including the Assign Group Permissions section. If you meant the normal Linux/Unix system user log ins, then I agree, in at least my case (no YP set up) the two users are unique but as noted, both have permissions to the audio library locations local to each machine.
