That is strange Dennis. I'm not worried about it because everything works just fine.. I.E. File transfers, internet browsing, downloading email transfers...ect..ect.. But my whole point is in trying to find out if this is a kernel bug in 2.4.20 or netstat. The bug being the fact that this MSS value is being reported incorrectly. I think its a Kernel bug because If I use "route -nee" I get the same info. Maybe I don't have something checked in my kernel menu-config that needs to be checked so that these values I.E.. "mss".. are reported correctly. Or am I completely missing something. This is also why I wanted to see what other peoples experiences and "netstat/route" output generated. > BTW: MTU != MSS Yes thanks. I knew this already. > MSS should be MTU - 40. But I don't think netstat is telling the > truth here... What makes you say the above Dennis? I would like some facts if possible. From what I've read and come to understand sofar is that both an IP header and TCP headers are 20 bytes in size. So this value would = 40. So are you saying that Netstatand Route somehow says "no matter what" subtract -40 bytes for IP and TCP headers? Somehow that seems just as strange as your output of MSS ='ing "0". But then again this is all pretty new to me so I will be researching more of this as well as TCP and MSS and ethernet standards. Thanks, Joshua Banks __________________________________ Do you Yahoo!?
