i've got a strange problem with a windows client...
my server is redhat-linux 6.2...
I have a self written tcp-server program on my internal ip 10.10.5.20 on port
The client (10.20.100.10) is a remote-user with NT...
strace shows, that my server programm is in accept() state.
The client is constantly trying to connect to port 130, but no connection is
I cannot check the client machine (it's not mine) and the user unfortunately
says, that his program works 100%-fine and it must be a bug on my side...
There is an output of tcpdump below.
These 3 lines appear all the time.
Can anybody explain why a connection is not established ?
the client is connected via two cisco-routers, which I cannot check for problems
My reading is that the SYN of the client is acked, but why does the client send
an reset afterwards. If I telnet to port 130 from anopther machine in my subnet
the connect will establish...
