  • What indicates high thresholds in TCP statistics, especially Failed Connection Attempts?

    I am trying to learn about TCP statistics, especially Failed Connection Attempts. What value would indicate a high threshold? Also, what causes these errors to occur? Does this indicate an issue at the remote or local host? Or does it have to do with network bandwidth or lack of I/O, etc.? Thanks!

  • capture PLC-data in our LAN

    Our PLC-vendor is going to provide us collected PLC-data on a server in our LAN. Are sockets (port higher then 1024) the best way to do this? As we are AS/400-minded people, will FTP resolve this with the same performance? Or are there other possibilities? Please, please, give us some guidelines.
