There are three approaches to networking with Basilisk II: |
| 366 |
|
|
| 367 |
|
1. Direct access to an Ethernet card via the "sheep_net" kernel module. |
| 368 |
|
The "ethernet card description" must be the name of a real Ethernet |
| 432 |
|
your network administrator about the nets and zones you can use |
| 433 |
|
(instead of the ones given in the example above). |
| 434 |
|
|
| 435 |
+ |
3. Access the network through a "tuntap" interface. |
| 436 |
+ |
The "ethernet card description" must be set to "tun". |
| 437 |
+ |
|
| 438 |
+ |
TUN/TAP provides packet reception and transmission for user |
| 439 |
+ |
space programs. It can be viewed as a simple Point-to-Point |
| 440 |
+ |
or Ethernet device, which instead of receiving packets from a |
| 441 |
+ |
physical media, receives them from user space program and |
| 442 |
+ |
instead of sending packets via physical media writes them to |
| 443 |
+ |
the user space program. |
| 444 |
+ |
|
| 445 |
+ |
A virtual network configuration script is required and the |
| 446 |
+ |
default is /usr/local/BasiliskII/tunconfig unless you specify |
| 447 |
+ |
a different file with the "etherconfig" item. |
| 448 |
+ |
|
| 449 |
+ |
This script requires you that "sudo" is properly configured |
| 450 |
+ |
so that "/sbin/ifconfig" and "/sbin/iptables" can be executed |
| 451 |
+ |
as root. Otherwise, you can still write a helper script which |
| 452 |
+ |
invokes your favorite program to enhance a user priviledges. |
| 453 |
+ |
e.g. in a KDE environment, kdesu can be used as follows: |
| 454 |
+ |
|
| 455 |
+ |
#!/bin/sh |
| 456 |
+ |
exec /usr/bin/kdesu -c /path/to/tunconfig $1 $2 |
| 457 |
+ |
