<p>loadbars (0.5.3) stable; urgency=low</p>

<p>  * Introduce new param --hasagent. With --hasagent 1 loadbars will not<br />
    run 'ssh-add' which would ask for your SSH key password to add it to <br />
    the ssh agent. With --hasagent 0 (default value) loadbars will run<br />
    'ssh-add' on startup in order to add your SSH key to the SSH agent.</p>

<p>  * Add openssh-client dependency to the .deb package.</p>

<p>  * Some code bugfixing.</p>

<p> -- Paul Buetow <***@buetow.org>  Tue, 01 May 2012 11:57:27 +0200</p>

<p>loadbars (0.5.2.2) stable; urgency=low</p>

<p>  * Test release, to test the deb.buetow.org repo key sign stuff.</p>

<p> -- Paul Buetow <***@buetow.org>  Sun, 08 Apr 2012 15:23:53 +0200</p>

<p>loadbars (0.5.2.1) stable; urgency=low</p>

<p>  * Hotfix release, contains only a corrected version string.</p>

<p> -- Paul Buetow <***@buetow.org>  Sun, 08 Apr 2012 15:23:53 +0200</p>

<p>loadbars (0.5.2) stable; urgency=low</p>

<p>  * Initial .deb</p>

<p>  * Heavy code refactoring (more modular code)</p>

        <![CDATA[Ein nuetzliches Tool fuer die Analyse von Netztraffic (insbesondere TCP-Verbindungen) ist <a href="http://www.tcptrace.org/">tcptrace</a>. tcptrace nimmt einen Netzdump (in .pcap Format, z.B. erstellt per tcpdump) und kann saemtliche TCP-Verbindungen tracen und Satistiken erstellen. 

<small><pre>
root@venus:~# tcpdump -i any port 80 -c 100 -w /tmp/test.pcap
tcpdump: listening on any, link-type LINUX_SLL (Linux cooked), 
   capture size 65535 bytes
100 packets captured
100 packets received by filter
0 packets dropped by kernel
</pre></small>

Danach mit -b einen tcptrace Brief-Output erzeugen:

<small><pre>
root@venus:~# tcptrace -b /tmp/test.pcap 
1 arg remaining, starting with '/tmp/test.pcap'

Oder mit -l etwas mehr Statistiken zu jeder TCP-Verbindungen ausgeben lassen:

        <![CDATA[Es ist schon eine Weile her, und da ich einige Tage nichts mehr gebloggt habe, wollte ich dies mal wieder tun. <a href="http://loadbars.buetow.org">Loadbars</a> 0.5.1 wurde bereits letzten Monat released (diejenigen, die das auf <a href="http://freecode.com/projects/loadbars">Freecode</a> (ehem. Freshmeat) verfolgen (sich dort das Project subscribed haben) sollten dies schon mitbekommen haben. Neu ist eigentlich nur die Moeglichkeit die Einstellungen in der Konfigurationsdatei ~/.loadbarsrc&nbsp;persistent&nbsp;zu konfigurieren. Loadbars schreibt diese Konfig automatisch, sollte sie noch nicht existieren, und setzt saemtliche default-Werte. So lassen sie sich einfacher herausfinden und nach eigenen Interessen anpassen.<div><br /></div><div>Da ich nun die naechsten 2 Wochen Bereitschaft habe (d.h. weniger Dinge ohne Computer erledigen) ist die Wahrscheinlichkeit hoch, dass ich in der Zeit wieder etwas basteln werde :)<br /><div><br /></div><div><pre style="border-top-width: 1px; border-right-width: 1px; border-bottom-width: 1px; border-left-width: 1px; border-top-color: rgb(0, 0, 0); border-right-color: rgb(0, 0, 0); border-bottom-color: rgb(0, 0, 0); border-left-color: rgb(0, 0, 0); border-top-style: solid; border-right-style: solid; border-bottom-style: solid; border-left-style: solid; font-family: 'Courier New', courier; background-image: initial; background-attachment: initial; background-origin: initial; background-clip: initial; color: rgb(0, 0, 0); padding-top: 10px; padding-right: 10px; padding-bottom: 10px; padding-left: 10px; margin-bottom: 30px; border-top-left-radius: 7px; border-top-right-radius: 7px; border-bottom-right-radius: 7px; border-bottom-left-radius: 7px; font-size: 12px; ">Sat Feb 25 20:09:02 CET 2012
* Release v0.5.1
* Add config file support (~/.loadbarsrc) and it's possible to configure 
 any option you find in --help but without leading '--'. For comments 
 just use the '#' sign. Sample config:
 showcores=1 # Always show cores on startup
 showtext=0 # Always don't display text on startup
* Add hotkey 'w' which writes current settings to the configfile
* Remove --title option (no need anyway)
* Some code cleanups
* Some bugfixes</pre></div></div>]]>

Z.B. passt sich die Fenstergroesse automatisch der Anzahl der angezeigen Balken an. Es ist auch moeglich die Fenstergroesse mit den Cursortasten manuell zu beeinflussen. Der angezeigte Text wird automatisch ausgeblendet, wenn die Balken zu schmal sind, so dass kein Text mehr reinpasst und automatisch eingeblendet, wenn wieder genuegend Pixel vorhanden sind. Ein weiteres Keyfeature ist, dass (bisher nur rudimentaer) auch die Speicherauslastung visualisiert werden kann. Bisher leider nur RAM und SWAP Verbrauch. Die ganzen feinen Untergliederungen (Puffer, Paging usw) sind noch nicht drin, ist jedoch geplant.</div><div><br /></div><div>Hier das Changelog:</div><div><br /></div><div><div><i>&nbsp;Release v0.5.0</i></div><div><i>* Add stats for rudimentary memory and swap usage (--showmem option or m hotkey)</i></div><div><i>* Remove --width and --inter options</i></div><div><i>* Add --barwidth option, each bar is barwidth pixels now</i></div><div><i>* Add --maxwidth option, which represents the max total window width</i></div><div><i>* Auto disable text display if text does not fit into window (maxwidth) pixels</i></div><div><i>* Auto re-enable text display if text does fit again into window&nbsp;</i></div><div><i>* Key right increases window width by 100px and left decreases by 100px</i></div><div><i>* Key down increases window height by 100px and up decreases by 100px</i></div><div><i>* Set 'samples' default values from 1000 down to 500.</i></div><div><i>* No sporadic crashes on shutdown anymore</i></div><div><i>* Some internal tweaks, no separate event thread needed anymore.
