Version: 4.00 from 2011-10-19

(P) & (C) 1997-2011 by Peter Bieringer <pb@bieringer.de>, see copyright notice for more details
Original site of publishing: http://www.bieringer.de/linux/IPv6/ ; suggestions, comments and improvements are welcome!

Additional Applications

If you miss hint for the old inet6-apps based stuff, please goto Obsoletes
This section is now in building progress again, using glibc-2.1 based software...growing slowly (depending on given time)
For quickstart, look at given URLs on the status page

Electronic mail (SMTP & POP)

Sendmail (now natively supported), see IPv6-Status/Application for details
POP+IMAP+SMTP: try package imap or courier-mail, see IPv6-Status/Application for details, both are supporting IPv6 now

World Wide Web (HTTP)

Server:

apache
thttpd

apache|apache2 (HTTP server)

Current Linux distributions already contain IPv6 enabled package, e.g. "httpd".
See also Deep Space 6 / Current Status of IPv6 Support for Networking Applications

Configuration

See Linux IPv6 HOWTO / apache2

thttpd (HTTP server)

Current Linux distributions already contain IPv6 enabled package, e.g. "thttpd".
See also Deep Space 6 / Current Status of IPv6 Support for Networking Applications

Squid (HTTP proxy)

Current Linux distributions already contain IPv6 enabled package, e.g. "squid".
See also Deep Space 6 / Current Status of IPv6 Support for Networking Applications

Configuration issues

You have to adjust IPv4 only addresses to IPv6 ones like

Binding of addresses

udp_outgoing_address ::

udp_incoming_address ::

tcp_outgoing_address ::

ACLs

acl localhost src ::ffff:127.0.0.1 ::1

acl to_localhost dst ::ffff:127.0.0.1 ::1

acl all src ::/0

acl sitelocalsrc src fec0::/48

acl linklocalsrc src fe80::/64

acl globaldst dst 3ffe::/16 2000::/3

acl ipv4src src ::ffff:0:0/96

acl ipv4dst dst ::ffff:0:0/96

Disable WCCP

wccp_router ::

mozilla (HTTP client/browser) / Firefox / Seamonkey

Current Linux distributions already contain IPv6 enabled package, e.g. "firefox" & "seamonkey"
See also Deep Space 6 / Current Status of IPv6 Support for Networking Applications

A list of sites for testing IPv6 HTTP transport is available at IPv6.org: http://www.ipv6.org/v6-www.html
You can also try my server IPv6 only server: http://www.ipv6.bieringer.de/

SMTP server Postfix

Current Linux distributions already contain IPv6 enabled package, e.g. "postfix"
See also Deep Space 6 / Current Status of IPv6 Support for Networking Applications

Router ADVertisement Daemon

Current Linux distributions already contain the tool, e.g. package "radvd"
See also Deep Space 6 / Current Status of IPv6 Support for Networking Applications

General: Configuring and starting

See Linux IPv6 HOWTO / radvd

Secure SHell (OpenSSH)

Current Linux distributions already contain IPv6 enabled packages "openssh" & "openssh-server""
See also Deep Space 6 / Current Status of IPv6 Support for Networking Applications

Usage:

Test, if sshd listen on IPv6 port:

[root@gate i386]# netstat -A inet6 -ln | grep 22

tcp 0 0 :::22 :::* LISTEN

Client using IPv6:

ssh -6 ipv6address
ssh -6 hostname.ipv6.domain.net

Hint: don't worry, if you see no listening IPv4 port, an connect over IPv4 will work, too, client using IPv4:

ssh ipv4address

PPP

Section outdated, migration to Linux IPv6 HOWTO planned.

IPv6-enabled by the maintainers

Why?

The original ppp binary package distributed by Red Hat isn't IPv6 enabled.

ToDo

First, test your installed pppd, perhaps it is already IPv6 enabled: strings `which pppd` | grep ipv6 should show e.g. IPv6 options which are mentioned in the man page.

Distribution	RHL 6.2	RHL 7.1	RHL 7.2
ToDo	untested	untested	rebuild source RPM with IPv6 enabling patches

URLs

IPv6 enabling patches (for version 2.4.1)

ftp://ftp.bieringer.de/pub/linux/IPv6/ppp/

Version and filename of the packet:

Latest version I've tested for IPv6 is 2.4.1-2 (IPv6-enabled rebuild on a RHL 7.2 system)

IPv6 enabled rebuild and installation:

Download (or copy from CD) source RPM package
Install source RPM (will be stored at SOURCES and SPEC)

rpm -ihv ppp-version-release.src.rpm

Copy given patches to subdirectory SOURCES
Copy given spec file to subdirectory SPECS (or apply diff)
Build binary package

rpm -bb ppp-version-release.ipv6.subrelease .spec

Update existing version

rpm -Fhv ppp-version-release.ipv6.subrelease .i386.rpm

Configuration and use:

See initscripts-ipv6 for details.

TTCP

Section outdated, use Iperf instead.

IPv6-ported some time ago by Marc Mosthav, minor glibc-2.1 fix by Peter Bieringer <pb at bieringer dot de>

Why?

It's for measuring the TCP network throughput from one host to another.
The original software can't handle IPv6 addresses and can't be used in a mixed environment. So a ported version is needed.

Version and filename of the packet:

Current IPv6 enabled release is ttcp/ttcp+ipv6-2.tar.bz2

Unpacking, configuration and installation

Move into the source directory, create a main directory and change into it

cd /usr/src; mkdir ttcp; cd ttcp

Unpack the new source:

tar xIf your-path/ttcp-version.tar.bz2

Move into the source directory:

cd ttcp-version

Now compile:

make clean; make

And install:

make install

/usr/local/bin

Usage:

Server: ttcp6 -r
Client: ttcp6 -t HOSTNAME

Try also ttcp6 {-?|-h} for more information.

PTCP

Section outdated, use Iperf instead.

IPv6-ported some time ago by Marc Mosthav, minor glibc-2.1 fix by Peter Bieringer <pb at bieringer dot de>

Why?

It's for measuring the TCP network throughput by roundtrips.
The original software can't handle IPv6 addresses and can't be used in a mixed environment. So a ported version is needed.

Version and filename of the packet:

Current IPv6 enabled release is ftp://ftp.bieringer.de/pub/linux/IPv6/ptcp/ptcp+ipv6-2.tar.bz2

Unpacking, configuration and installation

Move into the source directory, create a main directory and change into it

cd /usr/src; mkdir ptcp; cd ptcp

Unpack the new source:

tar xIf your-path/ptcp-version.tar.bz2

Move into the source directory:

cd ptcp-version

Now compile:

make clean; make

And install:

make install

/usr/local/bin

Usage:

Server: ptcp6 -s
Client: ptcp6 -c HOSTNAME

Try also ptcp6 {-?|-h} for more information.

Your connection is via: IPv4
