sockets - Reading 802.1Q frames with specific VLAN tag under Linux -


Is there a way to get data for a specific VLAN tag frame? The frame being tagged by inputting htons (0x22f0) as input to all the VLAN sockets () I currently receive: 

  m_iSocketDesc = socket (AF_PACKET, SOCK_RAW, htons (0x22f0)); Numbytes = recvfrom (m_iSocketDesc, message_data, 1522, 0, null, 0)    
 
 
 I A similar requirement was to get a packet with a specific VLAN, I created a VLAN interface and forced it to my raw socket. Now I can send 802.3 frames, the kernel insert / removes the VLAN tag.  
     
  1.  
     Create the VLAN interface, you must have root access  
      add ip link link & lt; PhyInterface & gt; Name & lt; PhyInterface.VLANID & gt; Type VLAN ID VLANID Example: IP Link Link Link eth0 Name eth0.100 Type vlan 100  
  2.  
     Use the normal bind function in your application to connect to the VLAN interface Please. Eth0.100 in the above example.    
     You can specify the following two links for the sample code (I am the owner of the  not  code)  < P> Getting:  
     Receiving:  
     The only change is needed to bind the virtual VLAN interface instead of binding to the physical interface. Note that the received ethernet frames are un-tagged frames. Any frames sent to this interface will be automatically tagged with VLANID.

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...
