On several occasions my x510 mediaserver is inerfering with my network. all pc's that login to the network do not get an ip adress, windows gives a black screen with a mouse cursor when logging in. ia not able to log into the server, but i can ping it from a pc that is allready loged in. i cannot play music from it with my logitech squeezebox. after resetting the x510, the problem is over for a few days. is there anybody who has any idea?? i allready diasabled the remote options. rgds patrick

we have this nice program APP.
that we put on the server and on a workstation
it';s network testing app. end to end

it sends fast data back and forth between the 2. systems, end to end, it overloads the subnet on purpose.
it checks for errors and for low bandwidth
and more.

it works like the online speed tests you see.
but why better and is only on your subnet.
this is just one tool of many
try it?

PING proves little. (sure the target is partially alive sure (part of the 5 layer OSI stack is alive)
it's just this one command. here...
"Echo-request message" type8 code 0.
it's only a TCP-IP diagnostic mode.

you ping this out and the other echos back
it does not prove end to end communications at all. only the most lower layers. work.
Ping only checks raw ICMP socket,
this one line explains what it does.
" the ping program initializes, it opens a raw ICMP socket so that it can employ IP directly, circumvent-ing TCP and UDP" this tells All i need.

see that circumenting word, that means its not and end to end full test. not at all.
ever.

it's like looking at car in the drive way
PING, i see a car,
but does it drive?, who knows? not PING. or just looking at a car. parked.
PING IS ECHO, and proves only that the socket on the other end can see a ping and respond.

see RFC-792,
