I don't think my message went to the list. I'm trying again. thanks, --Felipe
Hi Nmap Devel list Ncat version 5.00 All on localhost SERVER: ncat -l 31400 CLIENT: ncat localhost 31400 This "chat" works only one way, and tcpdump "port 31400" confirms it. The client can send to server "hello world" and when server replies, it doesn't not show up in tcpdump, or on the CLIENT screen. What's wrong? I tried the --chat command, and --verbose doesn't give clues. I've read through http://nmap.org/ncat/guide/ncat-chat.html As a test, I tried: SERVER: yes | ncat -l 31400 CLIENT: ncat localhost 31400 and nothing shows up on either screen (but ram usage goes up slightly, around 20%) SERVER: ncat -l 31400 CLIENT : yes | ncat localhost 31400 Works as expected. The intended operation is also 100% successful on traditional `netcat' Felipe
