Installing gogoCLIENT on Linux

After a fair bit of installing the client on different versions of Linux, I've created a list of things required to successfully install it.  These work as of today.  If I find further fixes needed,…Continue

I'm trying to install the gogoc client on openSUSE 13.1.  I've followed the various instructions in other discussions about compiling the client.  However, I've come across another problem that I…Continue

I went to get the latest version of the Linux client source code and discovered the server has changed.  It's now apparently on gumroad.com.  What happened to the old way of obtaining the client?  Do…Continue

gogoClient on Linux and DNS

I have a Linux based firewall where I run the gogoClient.  One thing I've noticed is that if the tunnel is down, that computer will not connect to a DNS server.  I have 2 DNS servers, with IPv6 addresses and one with an IPv4 in my host files.  The IPv4 address is last.  Normally, if a server is unreachable, the next server in the list will be used.  I also run dnsmasq on the firewall and it too fails, when the tunnel is down.  Is there something in the gogoClient that's causing this behaviour? …See More

"I found the problem.  The package libstdc++48-devel was not installed on my system.  After installing it, I can now compile the client. "

"I downloaded the file from gumroad.  It appears to be the same version as I got 4 years ago.  Given all the problems that are now appearing, perhaps it's time for an update.  Things have changed over the past 4 years. "

gogoc client rpm

A while ago, I mentioned here about an RPM for the gogoc client on rpm.pbone.net.  Since I was building a new firewall, I thought I'd give it a try, instead of the usual compiling method I'd used in the past.  However, when I try running the client I get an error "(gogoc_dir=)The directory does not exist".  Has anyone else got this RPM to work?  Perhaps I should go back to the old way.  At least it worked.  I'm running openSUSE 13.1 64 bit and used gogoc-1.2-25.90.x86_64.rpm.tnx jkSee More

"I've seen that before when one or more parties involved in the packet exchange has a really slow or high latency connection.  I'm not coming in from GoGo6 to see this, but maybe that's part of the issue?"

Why is this site such a disaster lately???

For the past while, the gogo6 site has been a real mess.  I have tried it in 3 different browsers (Seamonkey, Firefox &  Chrome) and on both Linux & Windows.  In all cases, the page looks like crap, with some parts unreadable.  When will this be fixed?See More

Sybex Cisco Certified Network Associate book. Wait before buying

I have been studying this book with the intent of obtaining Cisco CCNA certification.  However, I noticed several errors in the chapter on IPv6.  I have been in contact with the author about this and he said he will be updating that chapter to correct the errors I pointed out.  I have the Deluxe Edition, 6th edition, revised and updated for 2011, but I believe the errors may also be in the 7th edition.  So, if it's on the shelf now, it will likely contain those errors.  Wait for one with a…

Good IPv6 reference book

I have noticed that many problems people experience are due to not understanding IPv6 and how it differs from IPv4.  There is one book that contains a lot of useful IPv6 information.  It is IPv6 Essentials, by Sylvia Hagen and published by O'Reilly.  It's available in both paper and e-book versions.  What's nice about the e-book version is purchasers are entitled to free updates.  I refer to this book…

IPv6 port scan site

I don't recall if I mentioned this before, but there's an IPv6 port scan site, which you can use to check your firewall on IPv6.
