unix - have to find the port number for a particulat ip address -


I need to find the port number of a server, I have the host name and the IP address. Is it possible? I need this when I try to connect to this server through Putin, by throwing it a network error: Connection rejected the error, which may be due to incorrect port number Thanks in advance < / P>

So you're searching for port number, listen on the SSI server on that system. Usually it is Port 22 (the famous SSP port), but you are right, it can be changed in the SSH server configuration. If so, then you have two possibilities:

  1. Ask the administrator of the SSH server for the port number

  2. Creating a network Scan the server that shows all open ports However note that it can be considered as abusive behavior and may be blocked in the middle path.

    But most likely you are facing another problem:

    And note one side: a server < / Code> is a service, often listening to a port, you can usually interact with a specific protocol "speaking" a reference to software running a system computer, usually But these days the network can be accessed through several servers operated on a system A system can be identified by its IP address, many people mislead it and referring to "system" refers to "server" which is simply false and technically confusing. is.

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.
