Connecting Ubuntu to Windows Network Share

Recently started sharing some files on a Windows 7 computer using Shares. Turned off the wizards and other dummified options and used an Administrator group in order to assign my local Windows account permissions to access the Share remotely. This wasn’t working, and it turns out, I needed to add the account name itself and could not use a permissions group. This worked… but, for some unknown reason, the share was no longer accessible after a reboot.

Next issue I had was producing a listing error when trying to use Nautilus to see the files on the share. I then tried using some terminal commands but was receiving a “Mount.cifs cannot allocate memory mounting Windows share” message. These Windows registry edits might have solved the issue I was having… or perhaps it was the samba updates that helped?

Linksys WRT54G Router as Wireless Bridge

DD-WRT_speedTestResults

With 2 desktop computers and 2 laptops with another desktop being added to the mix, I felt it was time to cut down on these wireless signals. My motivation is part security and part efficiency… with a dash of paranoia.

While looking through old electrical gear, I found a Linksys WRT54G v8 wireless router. Bells started ringing in my head.

I remembered reading an article on some custom firmware that allowed for routers to be turned into repeaters or a wireless bridge. When I looked it up, it turns out that the Linksys WRT54G v8 was a perfect candidate for this DD-WRT firmware.

There’s a few Youtube videos out there that will help you through the process, which seems intimidating, but really isn’t that complex. And for those preferring an text & image based tutorial there’s the bridge article by WIFI Planet.

For my particular router (the v8), I only needed to:

1. Download the files from the DD-WRT Router Database (for the heck of it, grab em all). http://www.dd-wrt.com/site/support/router-database
2. In the admin panel of my Linksys router apply the vxworkskiller firmware. After applying this firmware, your router can only be accessed from a computer via a static IP and FTP.
3. Used the included tftp.exe file to upload the micro_generic firmware to my router.
4. Rebooted the router again and then inside the newly installed DD-WRT firmware, I followed these instructions to set it up as a wireless bridge. http://www.dd-wrt.com/wiki/index.php/Client_Bridged

Besides the speed benefits, I also have a little more security as I can just unplug a single device and all my computers are immediately taken offline. Also going to rest a little easier knowing I don’t have a half dozen wireless signals traveling through my body all night long.

Solve Them Puzzles with a Little LSD

Some theorize that psychedelics create a state of mind that can lead to some profound spiritual or scientific discoveries. Others believe it just makes you loose your mind and hallucinate. Well, all I can say is that Cisco systems are slightly more complex than Legos and I’d prefer a hippy over alcoholic working in my I.T. department.

From Wired.com:

It must be changing something about the internal communication in my brain. Whatever my inner process is that lets me solve problems, it works differently, or maybe different parts of my brain are used, ” said Herbert, 42, an early employee of Cisco Systems who says he solved his toughest technical problems while tripping to drum solos by the Grateful Dead — who were among the many artists inspired by LSD.
