osx - Questions for Network Analyzing in Perl -


I am planning to create a network analyzer for my thesis, which receives the SNMP's MAC address of the hosts connected to the management Uses to Switch. From there, I will get the packets going through the switch through port mirroring, and then analyze it. For this, I'm using Perl though, I have two questions.

  1. Is there a way to scan the switch altogether? Let's say that my software is running on PC A, which is then connected to switch A's span port. Then switch A's FFT / 10 interface is connected to FAT / 10 of switch B I was told that unless both FAT / 10 extension ports are there, you will not be able to get the pack from Switch B. Is it true? If not, how will it work?

  2. Does Pearl support sniffing together packets from two different NICs? Assume that the SPAN port of switch A is connected to NIC A, and the SPAN port of switch B is connected to NIC B. Is there a library in Perl, which will allow me to mirror the packet together with both switches?

    Sorry if no one is able to understand the question. I have a hard time coming in the form of my mind as my delusion has already been wasted as it is.

    1: Yes, it is true that you need to connect both switches with port mirroring.

    2: This technique is called forking / threading / listening to the event. It is possible to use these methods.

    Here are some pointers:

c - Mpirun hangs when mpi send and recieve is put in a loop -

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
