protocols - are there specific echo and non-echo telnet ports -


I have some doubts about telnet and the echo that I have not found lucky with Google (also to say That I have done my homework)

  • Does the telnet specification say that there are specific echo ports and specific non-echo ports?
  • If so, is port 23 and 10001 specially different?
  • If conditional yes, then this is some version of the Telnet protocol specific; in other words they have been added after some specific recurrence of Telnet and / or are they fully compliant telnet clients and partially Do you complain?
  • What if there is a difference between any locale and remote echo? I believe that I am talking about resonance from the server side (remote echo?) But in any case what is this?

    I'm not sure if telnet / protocol is a specific child stack overflow site or not? If yes, can someone tell me there? All port numbers are registered in IANA and it is referred to as telnet for specification which is

    port assignment When service hosts (i.e., remote terminal access) are used for remote user access, this protocol is assigned to server port 23 (27 octal). It is L = 23

    RFC number RFC 862 for echo protocol which equally defines 

      TCP based EcoService One Eco Service TCP On the connection based application is defined as. A server hears for TCP connection on TCP port 7. Once a connection is established, any data received once is sent back. This continues until the call-user can not terminate the connection.   
     Port number 10001 is registered for "SCP configuration".

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...
