pemu-New Version 2007-07-12 Linux/Windowspemu-New Version 2007-07-12 Linux/WindowsHow to use
!!!!!!!!!!!!!!!!!!!!!!!
This is Linux Version, It can’t be compiled directly on Windows
or any other platforms. There is separate windows version!
This version requires 32 bit CPU (or 64Bit CPU in 32 bit mode)
!!!!!!!!!!!!!!!!!!!!!!!
I. Compile from source, use this only if you know what you are doing,
otherwise, try compiled version.
Required – gcc3.4 – qemu is not compatible with gcc 4.x, so you will need
3.x.
1. Edit Make file, and customize line:
TUNE_FLAGS=-march=pentium4 -mtune=pentium4
with whatever CPU you have (type man gcc to see possible types)
This is only for optimization! It won’t help to compile on non x86 CPUs
2. type make
Ignore warnings.
If you are lucky, it may compile, if not, try using compiled version
II. So you either compiled from source or decided to use binary version, how
to use for first time:
1. prepare flash file, execute following command:
dd if=/dev/zero of=FLASH bs=1k count=16k
2. Download PIXOS image from somewhere, it is tested with 6.35, 7.22 and 8.02
3. There is no need to uncompress image (as it was in older version).
edit pemu.ini, it should look like:
—–
serial=0×12345678 <— PUT Your Serial Number here
image=pix <— PUT YOUR PIXOS image name here
key=0×00000000,0×00000000,0×00000000,0×00000000 <— PUT AC if You USE 6.x
bios1=mybios_d8000
bios2=bios.bin
bios_checksum=1
—–
Don’t enter any spaces, or empty lines or something else, as it will not
work!
if you already have image installed in flash, edit the second line to:
image=NONE
Copy Serial No and key from your existing pix, and save file
Activation Keym, set in pemu.ini is used only for PIXOS 6.x version!,
For PIXOS 7.x and 8.x, key should be entered with activation-key command
Serial No should be in HEX!!!!!
You should Use Serial No and activation key from existing pix. PIX model
in not important. E.g. You can use SN and AC from pix 501, 506, 515, etc.
Serial Numbers and keys from ASA are not compatible.
edit ifup.ini to configure how interfaces are initialized it should look
like this:
——
tap0 10.0.0.1 255.255.255.0
tap1 10.1.0.1 255.255.255.0
tap2 10.2.0.1 255.255.255.0
tap3 10.3.0.1 255.255.255.0
tap4 bridge eth0
——
virtual ethernet interfaces are specified using options like this
“-net nic,vlan=1,macaddr=00:aa:00:00:02:01 -net tap,vlan=1,script=ifup”
Up to 5 interfaces can be specified, but different mac addresses should be
used if connecting several virtual pixes
FINALY, run emulator with:
./pemu -net nic,vlan=1,macaddr=00:aa:00:00:02:01 -net tap,vlan=1,script=ifup -net nic,vlan=2,macaddr=00:aa:00:00:02:02 -net tap,vlan=2,script=ifup -serial stdio -m 128 FLASH
As from version 2007-07-02 there is new method of connecting to network -
called lcap (something like pcap but will probably work only on linux)
Using lcap, packets can be directly send and received via host ethernet
interface. Eample of ussage:
-net nic,vlan=1,macaddr=00:a0:00:00:00:01 -net lcap,vlan=1,ifname=eth0
This will directly connect eth0 and pix’s ethernet0 without any external
programs or bridging tricks. WARNING – using this method will not allow
traffic to/from host computer to emulated PIX
This code is still very experimental and in some cases it might not work.
The latest argument is FLASH image file, -m 128 means 128 MB RAM, which is
required for 7.x
for 6.x -m 32 is enough
Program is terminated with ctrl-c, there are other ways to use serial
console, read qemu manual for more info.
example -serial [url=telnet::1234,server,nowait]telnet::1234,server,nowait[/url] In this case serial console
is accessible with command: telnet localhost 1234
