It was fun while it lasted: Barracuda Copy – Copy End-of-Life

Posted by jpluimers on 2016/02/05

Copy had some advantages and disadvantages. For instance, it was better handling long file names, character encodings in filenames and a lot easier to configure over a CNTLM proxy than DropBox, but unlike DropBox didn’t keep history of changes.

Alas no more copy.com as of 20160501: [WayBack] Barracuda Copy – Copy End-of-Life.

They suggest using [WayBack] Mover with OneDrive as target: [WayBack] Barracuda Copy – Moving Your Data from Copy

Note that Mover has many more connectors, including cloud storage ones (Box, Copy, Dropbox, Google Drive, OneDrive and Yandex.Disk are free):

[WayBack] Connectors • Mover: FTP, Dropbox, Box, GoogleDrive, Copy, Egnyte, Amazon S3, SharePoint, MySQL the list goes on!

For me it means it’s time to think about what kinds of cloud storage I want to use and how to share what data with others at which access level. As I’m already contemplating on how to use ZFS, I now have two storage concepts to think about.

Batch file to open a specific TCP port in Windows 7 / 2008 Server and up

Posted by jpluimers on 2015/09/18

Thanks to the answer by Kevin Richardson on How to open ports on Windows firewall through batch file, I wrote this batch file that uses the add command of the Netsh AdvFirewall Firewall Commands which requires Admin privileges to run:


:: open port (first argument passed to batch script, second argument is description)
:checkPrivileges
net file 1>nul 2>nul
if '%errorlevel%' == '0' ( goto :gotPrivileges ) else ( goto :getPrivileges )
:isNotAdmin
:getPrivileges
echo You need to be admin running with an elevated security token to run %0
goto :exit
:isAdmin
:gotPrivileges
netsh advfirewall firewall add rule name="Open Port %1 for %2" dir=in action=allow protocol=TCP localport=%1
:exit
::pause
exit /b

Was ist Cloud? Great presentation including transcript by Kristian Köhntopp.

Posted by jpluimers on 2015/08/23

When one of my DevOps friends asks: Was ist Cloud?.

Kristian Köhntopp even published it as a SlideShare deck with transcript: Was ist Cloud?.

There is even a video: Froscon “Was ist Cloud?” – Video.

Thanks a million, Kris, this is very much worth reading for anybody doing Ops, Dev or DevOps.

There is even a

Blast from the past: the digital highway as imagined circa 1995.

Posted by jpluimers on 2015/08/07

Blast from the past: the digital highway as imagined circa 1995 (thanks Kristian Köhntopp for sharing this a while ago).

Learned a new phrase too (handfeste Datenträger) for something a marching band friend of mine was involved in: before he suddenly passed away at 39 he was a “high bandwidth courier” giving meaning to the phrase by Tanenbaum “Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway” by driving around magnetic tapes and optical media between various locations for about 600+ km a day.

Who could imagine in the age where ISDN at home (@ 64 kibit/s) was fast, that 20 years later you could have fiber (@ 500 Mibit/s) at home both for like EUR 50/month.

Like Steve Streeting posted: having high bandwidth (relative to the time you live in) makes you stop thinking about your internet speed

It allows you to find new usage patterns. Which is good for imagination, work, etc.

PS:

I lied a little. EUR 50/month is for the subscription only. Nowadays that means a permanent connection. In the ISDN days having a permanent connection to an ISP would set you down another EUR 50/month for the ISP, and about EUR 600/month of data usage to the telecom provider.

I did that for a couple of years until cable and ADSL became available. Why? Because it was the fastest way to stay informed (gopher, newsgroups, mailing lists, early forums and web-sites) and get the latest software (mainly over FTP).

Imagine this was only years after not even HCC being able to sustain the costs of a Fidonet transatlantic link, and now two decades later. I’ve posted about Fidonet before, and back-then it was the most affordable way to access information from across the world.

Now less than a century after the first transatlantic phone service was established in 1927, world wide communication is almost free (and there is even internet in space).

PPS:

Swets – where my friend worked for filed for bankruptcy last year. No more high bandwidth couriers…

ENDIAN Firewall – Connected client can access EFW but no other hosts: enable promiscuous mode on VMware ESXi

Posted by jpluimers on 2010/10/12

While solving a problem with Windows 7 machines not being able to ping the machines on the GREEN LAN of an Endian when connecting through OpenVPN, but XP machines could, I did a few upgrades, then went on to solve the problem.

  • Upgraded from ESX 3.5 to ESXi 4.1 (I needed this anyway because of Pass Through USB support)
  • Upgraded the community edition appliance from Endian 2.2 to Endian 2.4 (which has more configuration options, and better ways for reporting and logging)

Then I went on solving the issue, which I suspected was a kind of routing problem. Read the rest of this entry »
