In 4.8 and 4.9 is the legacy code. When it doesn't work between a 4.x client and server then the TTCP as such is broken. My changes (tcp hostcache) are in 5.2 for the first time. Before it it's the legacy code as well. I hope I haven't broken TTCP more than it was before. > and solaris(but i guess they don't do ttcp) and linux (not yet). Linux never will. They consider TTCP broken by design. Solaris I dont know. The problem is that TTCP will never make it mainstream or even little side stream. FreeBSD is the only BSD implementing it. Removing it would make maintainance of the tcp code a bit easier. Yet there are a couple of our FreeBSD folks emotionally attached to it (but they do not actively or even passively maintain it). -- Andre
