My ncat redirection runs quite happily until for several hours then stops accepting connection with the following error New connection denied: connection limit reached (100) I guess this makes sense but I'm pretty sure I don't have 100 simultaneous connections via ncat as each connection should be being closed down after connection am I missing something or is there a value i can use with --max-conns that tells it to just accept unlimited connections.Thanks for this report. What is the command line that you use?ncat -l server1 143 --max-conns 100 --sh-exec "ncat --ssl imap.gmail.com 993" I know 100 is the default but if you set it to say 10 you get the same behaviour it kind of feels like its doing a count of total connections rather that simultaneous connectionsAnother question: is this on Windows or another operating system?
