how to debug a client-server connection

[lists.j...@symetrie.com]

Hi,


I used the 4.2 mac client with my server without any pb.
I upgraded to 4.4, installed the 4.4 mac client.
Since this, I cannot connect (the client doesn’t see any connection, hence no db, in Profiles).

The strange point is that sao works correctly on this server: working from the browser through sao is possible.
The mac client works well with a 4.4 trytond running on localhost.

Is there a way to debug the connection problem with this 4.4 mac client ? for instance, enable a log file of his attempts to communicate ?

I already tried to clean up the known_hosts file.
I tried to give the server ip instead of the host name too.
telnet myserver 8000 shows a connection for a few seconds (no reply to ‘GET /‘).

You can lunch the client with --debug and --verbose flags to see what's
happing.

The same options are also avialble on the server.

Are you sure the server is listening to the ip you are accessing?
There is any firewall blocking the comunication? Maybe the mac client is
blocked by some firewall on your host.

Hope it helps.

Tryton client demands official certificates to connect to ssl else it
blocks with no warning.

Thanks, that’s the point. I have a cacert.org certificate but Tryton client maybe doesn’t ask the MacOs Keychain for the root certificate.
Either a warning should be emitted by the client, or this need be officially stated on the tryton website...

You can configure your own CA to use by the client:
http://doc.tryton.org/4.4/tryton/doc/usage.html#configuration-file

Normally, in verbose mode, there should be a error log displayed in case
of SSL error.
But I agree that we should show more information to the user:

Hi Cedric,

I was using the compiled client, that’s why I didn’t have a log.
I’ll try with tryton source to see the log and contribute if I can.

You can still pass arguments to the compiled client.

Didn’t think I could. So I tried.

~$ /Applications/Tryton.app/Contents/MacOS/tryton --verbose -l DEBUG -d

INFO:tryton.rpc:common.server.version(None, None)
ERROR:tryton.rpc:[Errno 54] Connection reset by peer

This error is not very clear :/

I finally solved this connection pb after adding intermediate certificate on top of .config/tryton/4.4/ca_certs file
and deleting again .config/tryton/4.4/known_hosts.
Good to use GTK client, often faster than sao in Firefox.
