Our office has a /24 IPv4 and a /48 IPv6 network.
Test to see if it would be possible to run parts of the TERENA Secretariat office network on IPv6 only.
This page keeps track of progress, bugs, and issues with this transition.
I will start with all systems and services that are used only internally.

To avoid name resolution problems, it was necessary to copy to the legacy 127.0.1.1
entries to ::1
:
127.0.0.1 localhost 127.0.1.1 ldap.terena.org ldap # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback ldap.terena.org ldap

NAT64 |
|
|
DNS64 |
|
|
Cisco 3750 does not support IPv6 access lists on VLANs |
Needs replacing in 2011 anyway. New box might support NAT64? |
|
Sharp AR-M276 |
This copier/printer does not support IPv6 at all. |
|
HP Laserjet 4250 |
Jetdirect J7949E does not support IPv6. Replace this with the JetDirect 635n. |
|
Google Mini does not support IPv6 |
Needs replacing in 2011 anyway, but don't forget to check!! |
|
Windows 2003 + MS SQL 2005 + Exact Globe 2003 != ?? |
Check if this works... |
Some tests indicate the Ecdysis works well.
Also, they presented at our own conference last year
Take into consideration!
Linux issues
|
PECL radius |
IPv6 doesn't work. Needed for TERENA web site. Considering rewriting code to use LDAP. |
|
apt-get |
|
|
Pear Net_Socket |
Does not like IPv6 addresses, wrote patch. |
|
ntp |
|
|
ntp |
dumps core without IPv4 loopback address. Keep legacy 127.0.0.1 address |
|
Confluence and JIRA LDAP auth via IPv6 = b0rked |
Workaround: use IPv6 only hostname: |
|
Radiator |
Cannot use IPv6 LDAP server. Filed support ticket at Open.com.au. Fixed as of 2011-02-12. Also make sure to add flags to any custom perl hooks: |
|
Listmanager |
Custom email list manager, running on Erasmus. 2 lists were doing queries to |
Windows issues
|
WinSCP |
Upgrade to 4.2.8 or later to get IPv6 going |
|
EMS PostgresQL manager |
Tunneling via SSH does not work. Native Postgres connections work, so the bug must be in |
|
TurtoiseSVN |
I had some repositories checked out with TurtoiseSVN, using my SSH keys from Putty/Pageant. Any actions on the repository started to have a really long delay after switching off IPv4 on the subversion server. Fixed after using the right repository URL format, in my case using the Putty session name instead of the host name. This session has everything set properly already. In my case the hostname is |
|
Remote Desktop client ( |
A RDP (Remote Desktop) connection to a Windows 7 computer using a hostname that only has a AAAA record takes 11 seconds. |
Mac OS X issues
|
Autoconfiguring name servers does not work for Mac OS X |
Macs need manually configured name servers, boo! |
|
CIFS client on Mac OS X does not support IPv6 |
Unable to file bug report due to lame web site ("An error has occurred. Please report the error to Apple Inc. by emailing the error detail to devbugs@apple.com.") |
|
CyberDuck does not work with IPv6 hostnames |
Use either literal IPv6 address, or IPv6-only host name |
Misc
|
Axis Q1755 web cam |
Can be configured to do IPv6, but only PING works |
|
VMware ESXi, Vcenter, VCB. These SHOULD work. Curious if it really works |
|
|
HP and Sharp printers, but we need IPv6 ACLs first |
|
|
Cisco AnyConnect |
Client get IPv4 + IPv6 address from the office, so remote user can access all IPv6 services |
