HTCondorWiki: How To Enable Ipv Six

Page History

We added preliminary IPv6 support to Condor 7.7.5. As of 7.7.5, this functionality is experimental and is disabled by default. You can enable the support if you would like to try it out.

IPv6 support is available in 7.7.4, but has a severe bug where the condor_starter will likely crash when attempting to connect to another computer over IPv6.

Limitations

Later versions of Condor should remove all of these limitations.

Authentication is not supported. This is extremely insecure.
Microsoft Windows is not supported.
Mixed IPv4/IPv6 pools are not supported.
You must use NO_DNS=TRUE, with all of those ramifications.
You must set NETWORK_INTERFACE to a specific IPv6 address.

Notes

In places where Condor is expecting an IP address and a port (e.g. "192.168.0.1:9618"), IPv6 addresses must be wrapped in [square brackets] (e.g. "[fe80::862b:2bff:fe98:65f2]:9618").

Enabling IPv6

NO_DNS = TRUE
# NO_DNS requires a default domain name.  NO_DNS
# creates artificial hostnames similar to
# 2607-f388-1086-0-21e-68ff-fe0f-6462.example.com
# where the first portion is the computer's IPv6 address
# with dashes replacing the colons.  The second part
# is the DEFAULT_DOMAIN_NAME.
DEFAULT_DOMAIN_NAME = example.com

ENABLE_IPV6 = TRUE

# This should be the IPv6 interface for this computer.
NETWORK_INTERFACE = 2607:f388:1086:0:21b:24ff:fedf:b520

# This is the NO_DNS style name for the central manager
COLLECTOR_HOST = 2607-f388-1086-0-21e-68ff-fe0f-6462.example.com

ALLOW_READ=*
ALLOW_WRITE=*
ALLOW_ADMINISTRATOR=*
ALLOW_CONFIG=*
ALLOW_SOAP=*
ALLOW_OWNER=*
ALLOW_NEGOTIATOR=*
ALLOW_DAEMON=*

NETWORK_INTERFACE is required; used for detection of scope ids.

To Do

Is the changing meaning of $(HOSTNAME) with NO_DNS even present in IPv4? File as a bug.
