20. Remote Access Proxy Out
One advantage I've had is the ability to use a proxy into my home network.
I setup my firewall/router to allow port 22 in to an Ubuntu machine at my house
This allows for remote access of my wife's machine as well as monitoring systems at home.

23. Virtual Environment VirtualBox Open Source Edition (OSE)
Sun (Oracle?) Edition

28. Virtual Environment
VMWare

29. Virtual Environment VMWare Free and Paid Versions
Better USB Support in past

31. Virtual Environment VirtualBox networking NAT Download Speed Fine
NAT Upload Speed 1/10th or Worse

32. WINE
Office Documents

33. Virtual Environment Virtual Machine Not Always Needed WINE
No Linux equivalent for Visio
Word Documents - .docx – open fine in OOo 3.1
Excel Wine crashes regularly.
.xlsx documents open fine in Calc
Discuss WINE
Windows is Not an Emulator
Works for many Windows Programs
Limited to Non – NT applications – Office, IE 6, Older apps

35. WINE
MS Word 2007 Under WINE
Next slide shows Office 2007 – Word – running under wine.

36. Word 2003 – and 2007 – would often start much faster than Open Office.
When I was using OOo 2.x, I did some comparisons between Word 2003 on WINE and OOo 2.x native.
Word would start and open a document in 10 seconds or less.
Open Office would start and open the same document in roughly 30 seconds.
Open Office 3.1 is much faster than before.
Also compare the two slides – previously Open Office would not handle Revision Tracking as well as Word in Native Word documents.
Next Slide

37. Now, with Open Office 3.1, revision tracking is no longer an issue.

38. Also with Open Office, you can view Excel 2007 files without a problem.

39. ISSUES
What are some of the issues and pitfalls of running Linux in a Windows environment?

40. ISSUES Limited Support
When running Linux in a windows environment there will be less support for your system – if it breaks, too bad.
You may also need to search out drivers and solutions on your own time.

41. ISSUES Limited Support Inability to Natively Test Some Applications
Working in a Virtual environment – using either VMWare or VirtualBox – is sufficient for most applications
There are issues with blackberry, and uploads

42. ISSUES Limited Support Inability to Natively Test Some Applications
Compliance with Standards
In many cases, the IT department will impose restrictions.
In my instance, it was encryption. Hard drives on laptops have to be encrypted. LA County chose PointSec.
Also, with the VPN, the Cisco IPSEC client worked just fine. The Juniper sslvpn client works for some things but doesn't allow for Linux-based remote desktop support.

43. ISSUES Limited Support Inability to Natively Test Some Applications
Compliance with Standards
Confusion in Describing Solutions to Others
Being an IT manager, I often am volunteered to show others how stuff works.
In my instance, I must think through how items work in Windows and then describe it.
This also occurs when – for example – showing presentations.
