Installing dtcp
It is known that the dtcp runs under FreeBSD, NetBSD and OpenBSD.
- Installing using FreeBSD ports or NetBSD pkgsrc
You can find the dtcp in ports/net/dtcp under FreeBSD or
pkgsrc/net/dtcp under NetBSD. So, if you are using FreeBSD or NetBSD,
it is better to use the ports or the pkgsrc for installing the dtcp.
The dtcp depends on the qpopper for the qpopauth command which is
included in it, to maintain an authentication database. Though, there
is some limitation in the dtcpauth, you can use it for a replacement
of the qpopauth.
Or, if you have no plan to use dtcps, perhaps you don't want to
install the qpopper.
If you are using the FreeBSD ports, you can prevent the qpopper from
being installed during installing the dtcp by the dependency from the
dtcp. If you don't want to install the qpopper, please specify
DTCP_CLIENT_ONLY=YES
as an option for the make.
- making dtcp by yourself
You can install the dtcp easily by running `make && make install' even
when you don't use the potrs nor the pkgsrc.
However, you may need to change the part of the dtcps.rb, dtcpc.rb and
dtcpauth.rb under some OSs.
The settings are for FreeBSD 4.6-RELEASE and later, and NetBSD 1.6 and
later by default.
If you are using other than these OSs, you may need to change
following constants appropriately. There are following constants to
be considered in dtcpc.rb and dtcps.rb:
- TUNIF = "gif0"
- The interface to be used for tunnel.
- TUNIF_CLONING = true
- Whether the virtual interface cloning (ifconfig
create/destroy) is supported or not.
- TUNNEL_CREATE = 'ifconfig %s tunnel %s %s'
- The command to be used for the tunnel creation.
- TUNNEL_DELETE = 'ifconfig %s deletetunnel'
- The command to be used for the tunnel deletion.
- ROUTE_METHOD = ROUTE_IFP
- The command type to be used for configuring routes.
- ROUTE_CHANGE
- route add -inet6 #{dest} ::1
- route change -inet6 #{dest} ::1 -ifp #{tunif}
- ROUTE_INTERFACE
- route add -inet6 #{dest} -interface #{tunif}
- ROUTE_IFP
- route add -inet6 #{dest} ::1 -ifp #{tunif}
- Other
- Set a route to a link-local address of a tunnel
interface of local side.
Next, if you want to use qpopauth, you need to change dtcps.rb for the
database in which APOP password is stored.
The settings in dtcps.rb are corresponding to the qpopper installed
from the ports of FreeBSD or the pkgsrc of NetBSD by default.
Otherwise, please change the part in dtcps.rb appropriately.
- POPAUTHDB = '/usr/local/etc/qpopper/pop.auth'
- The path for the database.
- POPAUTHUID = 'pop'
- The owner of the database.
There are same constants in dtcpauth.rb. If you have a plan to use
dtcpauth, please change it, too.
The rc scripts will not be installed. You can find the rc scripts for
NetBSD. If you are using NetBSD, copy these scripts into /etc/rc.d as
dtcpc and dtcps.
Don't forget to set execution bit.
If you want to run dtcpc and dtcps in daemon mode under other OSs, you
need to copy dtcps.sh and dtcpc.sh and custmize these appropriately.
Since the dtcp is written in Ruby, you need Ruby installed. If you
are using the ports or the pkgsrc, you don't worry about it. Ruby
will be installed according to the dependency.
However, if you don't use the ports nor the pkgsrc, you need to
install Ruby by your self.
If you are using NetBSD and planning to install Ruby from the pkg, at
least you need to install lang/ruby-base and security/ruby-digest.
