Hi, I am running FC7 32bit but, as I said, I am not very sure about this actually being related to AG3.1Beta or any other problems with the venue server itself. When it occurred there was no time to trace where the origin of the problem was... Venue server is AG3.0.2 running on FC6 32bit. About the autoplace, the only thing I found different from the reported in the ticket is that it occurs when clicking the 'quit' button (and not the Window Decoration 'X').

Hi Antonio, We're seeing the second problem (adding a new service when using unicast causes old ones to restart on a multicast address) here at RIT, running Windows XP. I just submitted a bug report for it ( http://bugzilla.mcs.anl.gov/accessgrid/show_bug.cgi?id=1678) --Andrew Ford On 7/12/07, Antonio Bandeira <bandeira(a)fe.up.pt> wrote: > > Hi, > > I've found a few "problems" with the new AG3.1 beta.

I was helping someone set up an AG 3.1 node yesterday and saw what appeared to be a similar problem. When a new service was added the system seemed to switch to multicast for all services. Not 100% sure this was the case, as I was setting it up remotely, but switching to multicast and then back to unicast fixed the problem... Brian

a few AG3.1 beta problems
by Antonio Bandeira 12 Jul '07

Hi, I've found a few ï¿½problemsï¿½ with the new AG3.1 beta. Donï¿½t know if it is just me, but... I am currently running FC7, but I think some of this problems can also be found in WinXP. - Bridge sorting is not persistent. After restart agtk the order is no longer the one set under ï¿½preferencesï¿½. - Working in unicast mode, adding a new service under ï¿½node managementï¿½ will cause all previously added services to restart using a multicast address. - Autoplace from VIC will not show up for the second time I try to set it. The first time I hit 'autoplace' in vic, it works fine. I can set it ok and when done I hit 'quit'. When I try to set it again, hitting 'autoplace' button in vic, it does nothing. I also had problems connecting to a 3.0.2 Venue Server with encryption set up. Vic was not able to connect. I am not very sure about this, but at that time, the only way to solve it was removing encryption from the venue configuration.

Hi Fred, Can you submit a bug and include your VenueClient.log with it so we can look into it? Thanks for letting us know. If you find any more issues, don't hesitate to submit them too.

Changing over to the beta1 of AG3.1 version has eliminated the problem and the new server has been very stable so far. I'm thinking about a release 7 of the AG3.0.2 packages which include the same prerequisites as used for the 3.1-beta1 packages (these prerequisites include m2crypto & twisted); maybe that will stabilise the 302 server. Having said that, its probably worth giving 3.1 a try. chris > Traceback (most recent call last): > File "/usr/lib/python2.4/site-packages/M2Crypto/SSL/SSLServer.py", > line 29, in handle_request > request, client_address = self.get_request() > FIle "/usr/lib/python2.4/SocketServer.py", line 373, in get_request > return self.socket.accept() > File "/usr/lib/python2.4/site-packages/M2Crypto/SSL/Connection.py", > line 125, in accept_ssl > return m2.ssl_accept(self.ssl) > SSLError: unexpected eof > > The venueserver is Slack 11 running AG 3.0.2 packages from Vislab.

Good afternoon all, I'm having a recurring problem that I have to restart our VenueServer every day or so. When I connect and open the screen session, its always the same M2Crypto SSLError: Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/M2Crypto/SSL/SSLServer.py", line 29, in handle_request request, client_address = self.get_request() FIle "/usr/lib/python2.4/SocketServer.py", line 373, in get_request return self.socket.accept() File "/usr/lib/python2.4/site-packages/M2Crypto/SSL/Connection.py", line 125, in accept_ssl return m2.ssl_accept(self.ssl) SSLError: unexpected eof The venueserver is Slack 11 running AG 3.0.2 packages from Vislab. I noticed new packages for Slack 11 (6e I think) and went ahead and upgraded last week thinking the new packages might fix the problem but its not. --- Jeremy Mann UT Health Science Center
