We are very happy to announce an update of the VERA Runtime libraries and the Vera IXPRouter library. This is mostly a minor update to correct small problems in compiling and using the IXPRouter library. Some relevant changes include: 1) Instructions on using WINE to compile microassembly code. 2) An enhanced user interface for the router 3) Various small bug fixes. The software is available at http://www.cs.princeton.edu/nsg/vera. Please feel free to post any questions. Zuki (for Scott Karlin and Wen Xu) -- Yitzchak Gottlieb zuki@CS.Princeton.EDU
Hi Zuki, I just try out the new released VERA. I met some problem during compiling. 1. I cannot find the file p3tosa.h metioned in Libixprouter/common/src/makefile LIB_HDRS +=p3tosa.h 2. After I comment out the line metioned above, all the Library was compiled succefully; However, when I try to compile IPmm application, it report some error like: ..../Vera/Libixprouter/sa/lib/libIXPRouter.a(control.o)(.text+0x124):fake: relocation truncated to fit: ARM_26 atoi I cannot figure out the reason. Wish you could give me some idea. Thanks, Best Regards, Qiu Qiang

Qiu Qiang, You are quite right, I seemed to have released slightly problematic code. The fix is, as you suggest to comment out that LIB_HDRS line in the Makefile. For the other problem I have attached a patch which should be applied to Vera/Libixprouter/sa/src/control.c it removed references to the atoi function and used a substitute available in Libsck. To apply the patch, simply run # patch control.c controlpatch Remember to keep a copy of the old control.c, and don't hesitate to point out any other bugs that you find.

Dear Scott and Zuki, It seems somebody raise the same question on how to setup Ping Program on VERA before; however, even I follow the instruction tightly, I still cannot make it work. Here is my system configuration [Host 1] ---> [0]IXP1200[1]<---[Host 2] Host 1: IP Addr. 192.168.133.146, MAC addr. 00:E0:29:00:8A:57" Host 2: IP Addr. 192.168.133.147, MAC addr. 00:E0:29:00:8C:AE" I add the following cache entrys to ipmm.c {"192.168.133.146", "192.168.133.147", "DE:F0:12:34:56:78","00:E0:29:00:8C:AE", 0x01}, {"192.168.133.147", "192.168.133.146", "12:34:56:78:9A:BC","00:E0:29:00:8A:57", 0x00}, Then, compile the Libixprouter.a with VRP. Running IPmm application: sgo ipmm.srec and using all the default setting in the released VERA software. When I try to ping Host 2 from Host 1, from the debug message, It seems that the packets was rcved, but the Microengine cache miss always occurs, and no packet is xmted. I have tried it in both Nov. Released Version and new Released version(With small modification on the atoi function calling in control.c, I guess no overall effect ) Wish you could kindly point out what I am missing. Thanks, Best Regards, Qiu Qiang
Qiu Qiang, The cache entries seem to be right. Are you sending 64 byte packets? (Using ping -s 22). What is the debugging output from the SA at the first cache miss? The first packets into and out of the router will certainly miss in the cache. What is the debugging output on subsequent misses?
