Me. :) // I've been racking my brain trying to figure out why my 3.0-current // box has been unable to telnet to my USR TC racks. I can telnet to my USR NetServer/16 without problem. Indeed, the problem here is not a permanent one. It happens just once in a while. // I get the connected message, and then nothing. tcpdump shows similar // activity to what's been posted. // // I traced it to a sysctl I had in /etc/rc.local that bumped the tcp // recvspace to 65536. // // Resetting it to the default clears the problem up. I'm using recvspace as 65336 too. I'll try lowering it next the time it happens.
