Problem with Hub to switch
I am writing in Linux forums after a long time :D
I have a network in my office (With Linux + Win Desktops, some are thin clients).
I am facing a strange problem.
I am having a dlink hub(8 port) and dlink switch(16 port).
Both are connected with crossover cable.
Machines connected to the hub can ping each other properly.
But when i ping a machine which is connected to a switch i get packet loss.
Also small packet ping is ok, but when i increase the packet size, the data loss occurs :(
ping -s 40000 <to a switch machine> = loss
ping <to a switch machine> = OK
ping <to a machine in same hub> = Excellent.
Switch to Switch is also OK.
I have changed cross over cable but its the same... And this same structure worked a few days ago fine!
Another hint for me was that, when i connect the cross over cable to the switch, the collision LED on the hub blinks a lot.. Otherwise its off.
