should be done soon.

I saw my port mentioned here!
So they cut out the libuuid stuff, and the multicast NIO which I had to sidestep anyways.

It's nearly 4am, and Im not in the right place to do a rebase, but look forward to a new update of the 'stable/unstable' and my mix of both the 'merge' exe's this week!

good to have copies.

to run some simple programs, and I setup an Infocom intrepeter, InfoTaskForce to run from cilo. I just received word it actually works on real hardware!

I copied it to flash and added
boot system flash ciscoload.bin

Release 37 / Serial number 851003

Another routine day of drudgery aboard the Stellar Patrol Ship Feinstein. This
morning’s assignment for a certain lowly Ensign Seventh Class: scrubbing the
filthy metal deck at the port end of Level Nine. With your Patrol-issue
self-contained multi-purpose all-weather scrub brush you shine the floor with a
diligence born of the knowledge that at any moment dreaded Ensign First Class
Blather, the bane of your shipboard existence, could appear.

Deck Nine
This is a featureless corridor similar to every other corridor on the ship. It
curves away to starboard, and a gangway leads up. To port is the entrance to
one of the ship’s primary escape pods. The pod bulkhead is closed.

Deck Nine Score: 0/4451

And they work building CILO on both Linux and Windows.

Now that I can acutally compile CILO! I don't know how useful it'll be for the world at large, but at the minimum I can do some basic benchmarking to see how performance is, inside of Dynamips now.

And it's a bear to build a MIPS-ELF toolset for Windows, so I know I'd want that out there.

I couldn't find this anywhere, but here we go.

dynamips.exe -P 2600 -r 128 -X -t 2611XM C2600-AD.BIN -p 1:NM-4E -p 0:16:WIC-2T -p 0:32:WIC-2T

By default the 2611 has a net module in slot 0, a dual port FE (CISCO2600-MB-2FE) so you can't change that. But you can put a net module in slot 1. WIC slots map weird. Also the 2611 is stuck to only 2 WICs.

well more so --sparse-mem. Using -X works fine.

I ran a one million packet ping, of 36 bytes to SLiRP, and I got the happy result:

"Success rate is 100 percent (1000000/1000000), round-trip min/avg/max = 1/14/616 ms"

So I'll release a stand-alone EXE for SLiRP first that works over UDP, then I'll see about adding it directly into Dynamips, so you can control it from there, and do things like add redirection.

Currently the hypervisor mode is broken. And the DLL only works when statically called, dynamic references break for some unknown stack corruption reason. (increase the stack of dll2.c ??) There is also far too much printf'ing going on. I may have to do that lame fprintf(stdout). I dont know or a macro for output. yuck.

Standalone MIPS and PowerPC work.
dynamips.exe -X -T 7200 -P 1700 -t 1710 -r 64 --idle-pc 0x80369ac4 c1700-y-mz.120-7.T.bin
dynamips.exe -X -T 7200 -P 7200 -t npe-150 -p 0:C7200-IO-FE -T 7200 c7200-is-mz.120-7.T3.bin... read more

Plus I updated the binaries. I think I may have included an -march=native build.... Also I got some more images to test.

I think this will trash the table layout...

So far the unstable MIPS emulator doesn't work at all. I've had much better luck with the unstable PowerPC emulator, but it's not 100%.

Yep, instead of two copies of Dynamips that can JIT one or the other on MinGW, I've managed to get both sides to compile into the same binary.

Really.

Testing has NOT been extensive, but I can load a 1710 and 7200 IOS image. I haven't tried it with the hypervisor to see if I can do both at the same time yet...

PowerPC
dynamips.exe -X -T 7200 -P 1700 -t 1710 -r 64 c1700-y-mz.120-7.T.bin

MIPS
dynamips.exe -X -T 7200 -P 7200 -t npe-150 -p 0:C7200-IO-FE -T 7200 c7200-is-mz.120-7.T3.bin... read more

and (C7200-IPBASE-M), Version 15.0(1)M runs and idles once you set a value.

There is still plenty of cleanup to do, and I still need to see if the latest GNS3 can drive this Dynamips. After that I'd like to see a Win64 build, so we don't have the 32bit memory space issues, although the only MinGW64 stuff I have want to be too much like Unix, so things fail all the time trying to build stuff with conflicts with winsock headers.... read more

I setup two routing instances, well basically two subdirectories, with the program and IOS in the parent.

r1

..\dynamips.exe -P 7200 -X --sparse-mem -T 7200 -t npe-200 ..\C7200-IS.BIN -p 0:C7200-IO-FE -s 0:0:udp:10000:127.0.0.1:10001

r2

..\dynamips.exe -P 7200 -X --sparse-mem -T 7201 -t npe-200 ..\C7200-IS.BIN -p 0:C7200-IO-FE -s 0:0:udp:10001:127.0.0.1:10000

And I've been running an extended ping, with the sweep size.... read more

And it is kind of tedious. You have to make sure your NPE has an ethernet device, or of course add in an Ethernet device.

dynamips.exe -P 7200 -X --sparse-mem -T 7200 -t npe-200 C7200-IS.BIN -p 0:C7200-IO-FE -s 0:0:gen_eth:"\Device\NPF_{0CFA803F-F443-4BB9-A83A-657029A98195}"

But yes, this works. Of course your ethernet device will be different than mine.

I will probably re-write the pcap code to be dynamic. I've always hated how Dynamips won't run without winpcap, and maybe I'm not going to use it...

So, first off I managed to get Dynamips to run on MinGW which was nothing short of amazing. Next I was able to rebase it againt the current github repo, and not only did it build, but JIT works too! And it is amazingly FAST!

I still haven't even tried to network it at all, there is most likely all kinds of bugs and crashes, but wow not bad!
