The "ethernet card description" is the name of an Ethernet interface. |

There are four 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 |
+ |
Prerequesties: |
| 446 |
+ |
- Make sure the "tun" kernel module is loaded |
| 447 |
+ |
# modprobe tun |
| 448 |
+ |
- Make sure IP Fordwarding is enabled on your system |
| 449 |
+ |
# echo 1 >/proc/sys/net/ipv4/ip_forward |
| 450 |
+ |
|
| 451 |
+ |
A virtual network configuration script is required and the |
| 452 |
+ |
default is /usr/local/BasiliskII/tunconfig unless you specify |
| 453 |
+ |
a different file with the "etherconfig" item. |
| 454 |
+ |
|
| 455 |
+ |
This script requires you that "sudo" is properly configured |
| 456 |
+ |
so that "/sbin/ifconfig" and "/sbin/iptables" can be executed |
| 457 |
+ |
as root. Otherwise, you can still write a helper script which |
| 458 |
+ |
invokes your favorite program to enhance a user priviledges. |
| 459 |
+ |
e.g. in a KDE environment, kdesu can be used as follows: |
| 460 |
+ |
|
| 461 |
+ |
#!/bin/sh |
| 462 |
+ |
exec /usr/bin/kdesu -c /path/to/tunconfig $1 $2 |
| 463 |
+ |
|
| 464 |
+ |
4. Access the network through the user mode network stack. |
| 465 |
+ |
(the code and this documentation come from QEMU) |
| 466 |
+ |
|
| 467 |
+ |
By setting the "ethernet card description" to "slirp", |
| 468 |
+ |
Basilisk II uses a completely user mode network stack (you |
| 469 |
+ |
don't need root priviledges to use the virtual network). The |
| 470 |
+ |
virtual network configuration is the following: |
| 471 |
+ |
|
| 472 |
+ |
Basilisk II <------> Firewall/DHCP server <-----> Internet |
| 473 |
+ |
(10.0.2.x) | (10.0.2.2) |
| 474 |
+ |
| |
| 475 |
+ |
----> DNS server (10.0.2.3) |
| 476 |
+ |
| |
| 477 |
+ |
----> SMB server (10.0.2.4) |
| 478 |
+ |
|
| 479 |
+ |
Basilisk II behaves as if it was behind a firewall which |
| 480 |
+ |
blocks all incoming connections. You can use a DHCP client to |
| 481 |
+ |
automatically configure the network in Basilisk II. |
| 482 |
+ |
|
| 483 |
+ |
In order to check that the user mode network is working, you |
| 484 |
+ |
can ping the address 10.0.2.2 and verify that you got an |
| 485 |
+ |
address in the range 10.0.2.x from the Basilisk II virtual |
| 486 |
+ |
DHCP server. |
| 487 |
+ |
|
| 488 |
+ |
Note that ping is not supported reliably to the internet as |
| 489 |
+ |
it would require root priviledges. It means you can only ping |
| 490 |
+ |
the local router (10.0.2.2). |
| 491 |
+ |
|
| 492 |
+ |
When using the built-in TFTP server, the router is also the |
| 493 |
+ |
TFTP server. |
| 494 |
+ |
|
| 495 |
|
FreeBSD: |
| 496 |
|
The "ethertap" method described above also works under FreeBSD, but since |
| 497 |
|
no-one has found the time to write a section for this manual, you're on |
| 504 |
|
not an Ethernet device, Basilisk II will display a warning message and |
| 505 |
|
disable Ethernet networking. |
| 506 |
|
|
| 507 |
+ |
Mac OS X: |
| 508 |
+ |
The "slirp" method described above now seems to work. |
| 509 |
+ |
|
| 510 |
+ |
|
| 511 |
