This is exactly the behaviour you want in a server that's on all the time - but exactly not what you want in a VM / laptop that gets paused regularly..

Thanks for suggestions, everyone. This does seem to be what's happening (despite the fact that the VM is running ntpd). Even quite a while after un-sleeping the computer, the VM continues to have an incorrect date, so ntpd doesn't seem to be doing a very good job here. An attempt to install VMware Tools for Linux turned out to be a headache (the VM doesn't have a number of things it wants, such as kernel header files). I abandoned that idea. I'll just shut down the VM before sleeping the machine, or maybe try to suspend the VM before sleep and see if that works just as well.

Re: [Catalyst] Tutorial (in VMware) keeps losing ability to authenticate
I'd guess the time in your VM is going crazy? (I.e. not getting updated).. Cookies (etc) are based on real time stamps - so if your VM gets very confused about the time, logins will stop working… Can you try just running 'date' inside and outside your VM - if these aren't close, that is almost certainly your issue..

Re: [Catalyst] Tutorial (in VMware) keeps losing ability to authenticate
I seem to recall have authentication problems with a Catalyst app a while ago, but only in the IE browser. IIRC the problem was something to do with the VM's clock losing sync and an IE cookies clash. Check the clock on your VM is accurate - worth a go :) Ben On 30 January 2013 21:10, Dan Lowe wrote: > I have been doing the Catalyst tutorial, at > > https://metacpan.org/module/Catalyst::Manual::Tutorial > > I am using the VMware virtual machine, as recommended.

[Catalyst] Tutorial (in VMware) keeps losing ability to authenticate
I have been doing the Catalyst tutorial, at https://metacpan.org/module/Catalyst::Manual::Tutorial I am using the VMware virtual machine, as recommended. This is running in VMware Fusion 5 Pro on a Mac. Overall it works perfectly fine, except that periodically, I lose the ability to authenticate to the demo CRUD app (MyApp). Based on observation, it seems that the only common factor is that it works fine before my laptop is put to sleep for the night, and it is broken in the morning. It doesn't seem to matter where in the tutorial I am. VMware, and often the Catalyst app server, are running when the laptop goes to sleep. (Arguably I should not do that, though the VM itself comes back just fine, and the app server still responds, it's just that I am no longer able to authenticate.) Things I have tried already: 1. Move the ~/MyApp/ directory aside, remove /tmp/myapp (session data cache), and run the server from e.g. ~/Final/Chapter05/MyApp. This results in the same behavior (app server runs, and response to http requests, but when authenticating, all I ever get is the "Empty username or password" error). 2. Reboot the VM 3. Reboot the Mac 4. Get to a working point, stop the app server, tar up ~/MyApp, and then next time it breaks, (stop app server) cd ~ rm -rf ~/MyApp /tmp/myapp (untar the copy of ~/MyApp) cd ~/MyApp ; script/myapp_server -r But that doesn't work, it exhibits the same behavior. 5. Delete ~/MyApp and /tmp/myapp and do the tutorial over again, pasting in all of the code from the web page. (This is the only approach that has worked so far, unfortunately.) I am just learning Catalyst (obviously), so I don't have any good theories here except that sleeping the VMware VM is corrupting something in its memory or filesystem, causing the trouble. Memory would not seem to be a legitimate suspect though, because rebooting the VM does not fix the problem. Whatever is wrong is persisting across reboots, i.e. it's probably on the filesystem. Does the tutorial cache data other than in /tmp/myapp? I have tried to find other caches, but since I am running unprivileged, it seems as if it would not be able to write outside of my home directory or /tmp, and I've already looked in both of those. I don't see anything under ~/MyApp that appears to be dynamic data, only in /tmp/myapp. Thanks for any advice, Dan ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/
