ipxnet (tunnel IPX over TCP/IP)
|
|
|
|
Host a standalone IPX network over tcp for old DOS games running in
|
|
dosbox.
|
|
|
|
For more information, see "https://www.dosbox.com/wiki/connectivity". Note
|
|
that the "Start IPX server" step is unnecessary when using this build
|
|
of ipxnet.
|
|
|
|
There are two use cases for ipxnet, with two separate executables:
|
|
|
|
- Users start the daemon as needed, and kill it when they're done. For
|
|
this, there's no need for an init script. The executable for users is
|
|
called "ipxnet". It logs to standard output only, and doesn't detach
|
|
from the terminal. The officially assigned UDP port number can't be
|
|
used, as it's port 213 and normal users can't bind to ports below 1024.
|
|
|
|
- Persistent daemon, that starts at boot and runs until shutdown. The
|
|
executable for this is "ipxnet-system", but you don't normally run it
|
|
directly. Instead, there's an init script. To make ipxnet start at boot:
|
|
|
|
# chmod 755 /etc/rc.d/rc.ipxnet
|
|
|
|
...then edit /etc/rc.d/rc.local and add:
|
|
|
|
if [ -x /etc/rc.d/rc.ipxnet ]; then
|
|
/etc/rc.d/rc.ipxnet start
|
|
fi
|
|
|
|
The default UDP port for ipxnet-system is 213. To change this, edit
|
|
/etc/rc.d/rc.ipxnet.conf, then run "/etc/rc.d/rc.ipxnet restart" if the
|
|
daemon is already running.
|
|
|
|
The ipxnet-system log file is /var/log/ipxnet.log. It will not be
|
|
overwritten when the package is reinstalled.
|
|
|
|
The ipxnet-system binary is installed setuid nobody and setgid nogroup
|
|
by default. If you want to change this, set IPXUSER and/or IPXGROUP
|
|
in the SlackBuild's environment. It's a bad idea to run this as root,
|
|
since it hasn't been audited for security. If you're really paranoid,
|
|
you probably will want to create a dedicated ipxnet user and group.
|
|
|
|
ipxnet-system also has the cap_net_bind_service capability set, meaning
|
|
it must be installed on a filesystem that supports capabilities (this
|
|
includes but is not limited to ext2/3/4 and reiserfs v3). This is required
|
|
for it to run as "nobody" yet be able to bind to low-numbered ports,
|
|
and is a much safer alternative to running it as root.
