Yepp. Synchronizing over SSL does not yet work. I have it on my to-do list since quite some time, but can't find the time to implement it. So at the moment you have to synchronize without SSL. 

 Hi,

Ok, to see if I understand. You mean setting SSL = 0 in my cfg file and leaving the rest as it is, right? Then I synchronize by hand and I guess I'll be prompted for the password. Perhaps I should remove my local password file to avoid that the password is send unencrypted?

Cheers,

That's correct. The password will be sent unencrypted if you get prompted, but if you use the automatic scheme the password will be encrypted (but not the logbook entries of course). But your concerns are right, running this thing not over SSL is a bad thing these days...

 Ok, thanks a lot! I'll try asap and report back.

Cheers,

Ricardo

Unfortunately I only got 1/2 hour to go back to this... I was trying to avoid copying the whole remote elog server from 20 people (that's what I get with the automatic cloning, right?)

So, I set SSL=0 and removed the password file, but still got the same result. Then I looked in the code a bit, and can see that the problem happens in retrieve_remote_md5(...) in the lines:

   p = strstr(text, "ELOG HTTP ");
   if (!p) {
      if (isparam("debug"))
         rsputs(text);
      sprintf(error_str, loc("Remote server is not an ELOG server"));

in elogd.c, where I see text is filled by retrieve_url()

So what seems to fail is that retrieve_url() gets back a string from the remote server which doesn't include the string "ELOG HTTP ". But I don't know what that really means. Here is what I get if I try:

bash-3.2$ /usr/local/sbin/elogd -v -m -p 8080 -c /usr/local/elog/elogd.cfg -D

I get the following output:

Retrieving entries from "https://www.pp.rhul.ac.uk:8080/ATLAS Trigger"...

Remote server is not an ELOG server

Your problem is here. I wrote that synchronization is not possible through SSL, but you try to access https://www.pp.rhul.ac.uk:8080 which is SSL (because you have https:// not http://). 

 Ah, I see. Hmm, ok it doesn't work without the s either. I can't access the server in that case. Ok, I think I'll just wait for this feature to be available. Thanks for your help!

 Of course you also have to switch your mirror server not to use SSL as well. You can check this then by accessing it directly via http://www.pp.rhul.ac.uk:8080/ATLAS Trigger from the same computer. Also make sure that you don't have any firewall issue.
