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

James Knott replied to Bruce Sinclair's discussion 'Large Scale NATs'
"Another thing that appears to be forgotten is NAT breaks some protocols.  For example, IPSec authentication headers cannot possibly work with NAT, because they verify the IP addresses and ports haven't been changed.  NAT also forces…"

James Knott replied to Bruce Sinclair's discussion 'Large Scale NATs'
"While NAT is possible on IPv6, there's really no need for it.  NAT provides no security beyond what's capable with a properly configured firewall."

"When pinging a link local address, you have to specify the port you're going out on.  Are you doing that? Here's what Microsoft says: http://technet.microsoft.com/en-us/library/cc780986%28v=ws.10%29.aspx"

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

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

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.
