Hi Dan,
Sorry to interfere in this discussion but after reading your last post, a question arises:
Has anybody been able to install successfully Evergreen on Ubuntu 7.04 following the instructions available on the Wiki? You indicated that you face these problems with Ubuntu 6.10. Now, if instructions have been written for 7.04, I suppose this implies that the installation is feasible on that distribution. Am I wrong? Should we abandon this path and try a new install on Gentoo instead?
Thanks,

Hi Pierre:
I don't think your configuration file is at fault; I replaced the ejabberd.cfg configuration file on my Gentoo machine with a copy of your file, changed one setting (cobaye-ti to my own hostname), and started up ejabberd successfully (going on to run Evergreen, etc, without any noticeable differences).
Maybe it would be worthwhile uninstalling ejabberd and erlang, and installing them again, then copying your configuration file into place and registering the users? It seems that the problem you're experiencing is entirely at the ejabberd / erlang level (which is sadly the obstacle that ultimately caused me to give up on Ubuntu 6.10 back when I was writing the install instructions for Ubuntu!).

Good morning Dan,
On my peregrination in the web to solve this problem, I never heard about these strange behaviours: you have to reveal this somewhere ! Thankfully, Google will harvest this mailing list...
Apart from that, these little tricks didn't help much : the ejabberd server is still dead calm...
I verified the ejabberd.cfg file for syntax errors (no problem), restart and stop ejabberctl and then ejabberd start : still, ejabberd won't work. Finally I reboot the machine, did a netstat -l -n : nothing on the ports that ejabberd is suppose to listen. Did again the little sequence of commands : again nothing from ejabberd.
This is so strange : before the capital letters problem, ejabberd was running nicely...
So I upload the ejabberd.cfg here ( http://www.bibliotheques.uqam.ca/flash_bugs/ejabberd_cfg.txt <http://www.bibliotheques.uqam.ca/flash_bugs/ejabberd_cfg.txt> ).
Thanks a lot,

Pierre,
I am glad (yet also amazed) that the case change fixed your registration problem. I do not think you really needed to go through and change all your other files and settings, but it shouldn't hurt if it was done accurately. As for your recent issues, you almost certainly have some syntax error in your ejabberd.cfg file (though I am not sure how it worked before). You are also running into some more ejabberd (on Ubuntu at least) weirdness, which I will now explain. To start ejabberd, you use the command:
sudo /etc/init.d/ejabberd start
which is fine and dandy, but it doesn't complain about syntax errors! It loads an erlang process which attempts to start ejabberd, but that part silently fails. You are left with a "Started" node but no running server, and attempts to register an account give the long nasty erlang error message you got. To make matters worse, when you are in this state, the following commands:
sudo /etc/init.d/ejabberd stop
and
sudo /etc/init.d/ejabberd restart
and
sudo /etc/init.d/ejabberd force-reload
NO LONGER WORK. The running node will both refuse to go down and will refuse to reload the (presumably) now corrected config file.
Thankfully, there is a solution not involving finding and killing the rogue erlang process (which would work as well). For reasons I have never bothered to fully look into, the following commands DO WORK:
sudo ejabberdctl restart
and
sudo ejabberdctl stop
!!!! So, why not just use ejabberdctl and forget about the 'ejabberd' init script altogether? Well, turns out that there is no 'ejabberdctl start' command. Hey, don't look at me, I didn't write it :)
That leaves us with the problem of finding your syntax error. If you want to upload the ejabberd.cfg file we can all take a look, but I would bet the line of the hour is the culprit:
{hosts, ["localhost"," cobaye-ti.bib.uqam.ca"]}.
Double check for matching " ",[ ], and { }, and also be aware that the period '.' at the end is a requirement.
Once you get ejabberd back together, I would suggest rebooting to clear out any half-running parts of the system and try again. Since this is obviously just a test machine, sometimes a restart is the easiest way to clean the slate.
Good luck,
DW

Hello Dan,
Yes, it worked : I registered the two accounts, the upper case letters
seems to be the problem. After registering the accounts, I tried to start
Open SRF but it give me the same error message. Then I remembered that the
capital letters were everywhere (opensrf.xml, opensrf_core.xml, .srfsh.xml).
I modified these files, restart Opens SRF: same error message. I change the
/etc/hosts and /etc/hostname files, reboot the machine. After that, ejabberd
was dead : the command sudo ejabberdctl status returned:
Node 'ejabberd at cobaye-ti' is started. Status: started
ejabberd is not running
Nothing on any ports (5222, 5223, 5269). Strange, as I just change the
capital letters. Euh.. this is an entirely new problem.
I tried to register an account, it give me that message:
RPC failed on the node 'ejabberd at cobaye-ti': {'EXIT',
{badarg,
[{erlang,
port_control,
[stringprep_port,
1,
"

{stringprep,control,2},
{jlib,nameprep,1},
{ejabberd_auth,
auth_modules,
1},
{ejabberd_auth,
is_user_exists,
2},
{ejabberd_auth,
try_register,
3},
{ejabberd_ctl,process,1},
{rpc,
'-handle_call/3-fun-0-',
5}]}}
I put the ejabberd sasl log file (
http://www.bibliotheques.uqam.ca/flash_bugs/sasl2.txt ). Do I have to
reinstall Evergreen (step 20) to change the capital letters in the
bootstrapping database host (cobaye-TI.bib.uqam.ca) ?
Thanks,
Pierre Nault
