Hi All, Looking at the attached diagram - My server is IP 10.x.x.x and the client is on 172.x.x.x. 10.x.x.x Server sits in Our DataCentre. The PC on 172.x.x.x is a DMVPN Site I have complaints from users at this site when using a system to upload/download files. I have about 20 other sites who use the system also with no complaints. Bandwidth Utilization at the sites is not saturated. Looking at the screenshot - does this suggest that it is my server having buffer issues? (10.44.145.196)? Trying to decipher what the actual messages are telling me. Thanks ![alt text][2] asked 23 Sep '15, 06:32  exit12 edited 23 Sep '15, 06:33 |
One Answer:
Yes your Server has a full receive window and the client tests if the window is still at the zero size. What is the OS at the server? answered 23 Sep '15, 09:51  Christian_R |
Hi Christian,
The server side is actually a Linux machine I believe. I've attached another screenshot from the conversation as I just want to understand what each part means.
Looking at packet 4248 - it looks like the server reports a TCP Zero window. What does the 8010 - 63607 numbers represent/mean? Also seen in packet 4305, 4509, 4788.
Thanks
8010 is the Source Port and 63607 is the Destination Port of that packet.
