p300 switching to Java 1.6?

guruz — Thu, 22 Jan 2009 12:20:15 +0000

The Java 1.6 features that p300 currently uses (splashscreen, tray icon) are included in a way so that Java 1.5 will still work.

However, I want to do some things that makes this not possible.

Is anyone still using p300 with Java 1.5? Because there is for example only 1.5 for OS X 10.4. Please tell me.

p300 got mentioned in German Linux User magazine!

guruz — Mon, 05 Jan 2009 18:55:37 +0000

Thanks a lot to cassmodiah for scanning me the short review of p300. It appeared in the 12/2008 issue of the German magazine “Linux User”. This is the first offline mentioning of p300 as far as I know

Merry Christmas!

guruz — Wed, 24 Dec 2008 16:27:18 +0000

Have some nice holidays!

I actually planned to do some p300 work these days, but I’ve got a lot of social obligations. Most of them I even do voluntarily

2 Years of p300!

guruz — Sat, 20 Dec 2008 11:27:49 +0000

As you can see on the p300 page on freshmeat, the first public release was 2 years ago. Hooray

Trouble with p300 and 64-bit Java on Windows?

guruz — Fri, 19 Dec 2008 17:53:19 +0000

You can contact me, I can give you a fixed version. The fix will also be included in the next version.

Thanks ShadowIce for mentioning and testing.

p300 1011 has been released

guruz — Fri, 05 Dec 2008 06:12:38 +0000

I’m happy to announce the latest version of p300

The changes are:

With the change from 3-character revision to 4-character, the auto updater was broken. This is now fixed for future releases. However, this means the auto upater is not able to launch revision 1011. You have to manually download it.
Allowing of hosts has been reworked to be more easy: p300 detects which hosts are on the LAN/VPN using multicast and broadcast UDP. These hosts are added to an “implicit allow” list. Implicit allow is only enabled for new p300 installation, not existing ones. You can enable or disable it in the webinterface.
Before a host is displayed as online, we make sure it is reachable with p300 HTTP. Fixes this bug.
There was a bug in certain Windows and Java versions when a complete drive is shared. This is fixed now.
Multicast TTL is now 100.
Removed the multicast device settings. They made no sense anyway since broadcast was also used.
Removed guruznetworkinterfaces.implementation.InterfaceInformationRetriever, it made no sense anymore.
Manual discovery in webinterface now also auto-allows the host.
Some smaller fixes, enhancements and internal refactorings.

If you experience any problems with network devices (like Hell4you does) in this release, please report.

Next p300 version about to be released in the coming days.

guruz — Tue, 02 Dec 2008 12:19:19 +0000

Just have to do some testing here and there. If you want to help, contact me.

p300 bug in Windows when sharing a complete NTFS drive

guruz — Thu, 20 Nov 2008 12:59:19 +0000

Blackout888 and oXyde reported a weird p300 bug that happens with various Windows (Vista, XP) and Java (1.6.0_04, 1.6.0_10) versions, but only in some cases:

Sharing of a complete drive (e.g. d:\) formatted with NTFS is not possible in systems affected by this bug. The reasons are currently unknown, the HTTP error reported by p300 will be “400 Not existing or not readable”.

I am currently absolutely unsure why this is happening. Is anyone else affected and can maybe tell more information?

Update 21.11.2008: new File(“d:\\”).isHidden () returns true if d: is a NTFS drive. p300 does not share hidden files, therefore the sharing will fail. Why Java / Windows behaves like that.. I don’t know, but I will look at it. But at least it means that this “bug” will be fixed in the next p300 version: On Windows we will also share hidden files.

Update 2 21.11.2008: It is actually already in the Sun Java Bug Tracker

Weird p300 connection problems

guruz — Sun, 09 Nov 2008 20:28:30 +0000

I have spent some hours with Hell4You debugging an issue with p300 connectivity on his network. The result of the issues were that browsing and chatting sometimes worked, sometimes it didn’t. By looking at the p300-generated hostfinder webpage and debugging around with the Eclipse debugger we were able to track it down: Some of his hardware / software is duplicating UDP packets and using its own IP as the source IP of the duplicated packet. Really really weird stuff. This resulted in connectivity sometimes not working because the wrong IP was used by p300.

The latest p300 version that will come in some weeks will fix this issue: It will always be checked with HTTP if some ip:port is really running p300. If you experience the same problem as described here, I can send it earlier

For the record, he is using a 3com OfficeConnect and a SpeedTouch 780wl.

Lesson learned? Never trust UDP!

p300 987 has been released

guruz — Mon, 20 Oct 2008 20:42:11 +0000

I have found the time to release the latest p300.

The changes are mostly bugfixes, thanks to all reporters (oXyde and more):

Fixed two very stupid bug in the downloader that prevented a download from finishing when it had multiple sources (e.g. if a host we are downloading from was reachable via LAN and via VPN)
Fixed another bug in the downloader that (sometimes?) prevented files over 2 GB from finishing
Try to more agressively send multicast packets. This should eliminate “bad argument for IP_MULTICAST_IF2: No IP addresses bound to interface” messages
Most options in the webinterface are hidden per default. There is a checkbox to have those options shown again
Moved some stuff from MainDialog methods in Action objects
Search edit field in main window gets the keyboard focus when window is shown or mouse is over the edit field
Link to iTunes store in the shopping search results (US, Germany, Belgium). Tell us if you need more
After click on send button in chat the input field gets the focus
“Open results in webinterface” button in the search results
Browse a directory directly from the search results
More options in the main menu
double click on LAN/VPN hosts in main window: Add a host
The search from the browse window now opens the new search GUI instead of the old webinterface search UI
The window for the upload log and the console should now properly auto-scroll (at least on Linux and OS X). Also, their size has been limited to 512 KB

Have fun

Version 876 of p300 has been released

guruz — Fri, 03 Oct 2008 10:45:14 +0000

Finally the long-awaited search function inside p300 is released

thanks to the hard work of Sebastian, the global search finally works! Yay!
- Please note that the UI for the search results has only the most basic features yet. more to come.
increased window size from 600×400 to 800×600
hostname for unique LAN identifier generation will be kept even if it changes. This should fix some duplicate hosts in the host list.
We now have a support webchat. Thanks to axod from mibbit!

First impressions of the p300 global search result window

guruz — Tue, 23 Sep 2008 20:09:18 +0000

While Sebastian is working on the core, I am currently doing the GUI part. Unfortunately, we are both very limited in time. But I hope it will only be 1 to 3 weeks for the next release.

Version 809 of p300 has been released

guruz — Wed, 17 Sep 2008 19:17:23 +0000

Version 809 of p300 has just been released. It is only a small bugfix release.

Changes:

Java WebStart should finally really work. At least let’s hope that. (bug of the last version)
The auto updater should work again. (bug of the last version)
Icon on send button in chat
Allow Hamachi IPs (Starting with “5.”) per default
Removed caption from search button in main window
When manually adding a host for discovery, it will automatically be allowed

Have fun and report any bugs you find!

Auto Updater of p300 broken

guruz — Sun, 07 Sep 2008 15:29:38 +0000

With the resource loading changes made in the recent 762 release, the auto updater of p300 is currently broken. If your p300 was auto-updated and does not start anymore, please download it manually.

Sorry for that

The p300 webinterface is broken when starting with Java Webstart

guruz — Wed, 03 Sep 2008 11:30:44 +0000

… but only on Linux and Windows. I suppose the problem has something to do with loading resources. I will look into that and release a fix in the next days.

In the mainwhile, download p300 instead of using Java Webstart

Update: Sebastian just reported that it works with OpenJDK 1.6.0_0-b11. So, maybe give it a try.

p300 revision 762 released

guruz — Wed, 03 Sep 2008 09:04:54 +0000

Finally, another release of p300. Let’s hope I have more time for p300 after my diploma thesis.

Changes:

menu button in main window
changed most of the tree items to menu items
changed main tree so that chat and webinterface of hosts are easier reachable
set focus to input edit field in chat window when opening
add share directly from main menu
simplified adding shares, sharename will be derived from directory name
ENTER to send in chat instead of CTRL+X
download button in GUI file browser
added Amazon.co.jp to shops
moved icons around in the JAR
automatic scrolling down in console and upload log
download completition percentage has now two decimal places
hidden files or directories in the shares cannot be acessed anymore
hide Sharemonkey buttons until the quality of their results improves
changed some internal things on how resources are loaded
better inclusion of Java Webstart on http://p300.eu/download/
updated icon shown im Java Webstart
added splash screen in Java Webstart
the ID used for identification in LAN will now contain the encoded hostname. this makes p300 work from multiple computers using the same home directory. Currently all will show the same display name though.
links to suggest feature and to send feedback

Have fun with it

Again, some p300 UI polishing

guruz — Sun, 31 Aug 2008 10:37:38 +0000

To make it easier to access the chat feature, I revised the main window UI again. If you hover over one of the hosts, 3 icons for the host will appear for Browsing, Chat and Webinterface

The window:

The icons:

(Hostnames blurred out)

To be released soon, contact me if you want it NOW
