aryx Posted June 24, 2006 Report Share Posted June 24, 2006 I have a server which uses utorrent's built in tracker.Then I have 12 LAN computers which downloads a torrent from this tracker, but...They all download just fine - but there are some issues:It seems like they don't upload anything they recieve. (The flag is D and the only peer is the server).In the connection column it shows 1(2) 0(12).What can be the reason for them not sharing the file with each other?There is also one other thing, suddenly it stops from sending data on certain clients for 1-3 minutes before it starts again. Why is that?Regardsaryx Link to comment Share on other sites More sharing options...
Ultima Posted June 24, 2006 Report Share Posted June 24, 2006 Firewalled from each other? Link to comment Share on other sites More sharing options...
aryx Posted June 24, 2006 Author Report Share Posted June 24, 2006 No, it is a classrom that is on a vlan. The server has one NIC and connects to four classrooms on four vlans.The ip address on the vlans is 192.168.20x.0 (x=1-4), with Default gateway 192.168.20x.1I noticed the ip config on the server was 192.168.20x.254.Could it be that the server dosn't send back a response to the correct ip subnet?

Klaus_1250 Posted June 24, 2006 Report Share Posted June 24, 2006 Take a look at the ip's of the peer (right-click in the peer-screen and use copy peers and paste them in notepad). Have you tried ping'ing / tracert'ing between pc's on the various vlan's and to the server? Sounds to make like a small glitch in the network setup, but that difficult to say with limited information. Link to comment Share on other sites More sharing options...
Switeck Posted June 24, 2006 Report Share Posted June 24, 2006 Due to routers/switches, there may be a firewalled condition between each vlan -- even though the individual computers inside each vlan are not firewalled to each other. Link to comment Share on other sites More sharing options...
aryx Posted June 25, 2006 Author Report Share Posted June 25, 2006 It might be an ACL on the VLAN switch, I'll take a look at that next time I'm at work.I'll to a tracert as well Link to comment Share on other sites More sharing options...
aryx Posted October 29, 2006 Author Report Share Posted October 29, 2006 It is still not workingThis is how the network setup is:3 x 24 port switches with 4 vlans.vlan 11 - Classroom 1 - 192.168.201.0/24vlan 12 - Classroom 2 - 192.168.202.0/24vlan 13 - Classroom 3 - 192.168.203.0/24vlan 14 - Classroom 4 - 192.168.204.0/24I seed from a server which has access to all these vlans, it's a network interface card that reads vlan information and has an IP address in each vlan:vlan 11 - 192.168.201.254vlan 12 - 192.168.202.254vlan 13 - 192.168.203.254vlan 14 - 192.168.204.254Can anyone see what I need to do to get this fixed? Do you need more information? Link to comment Share on other sites More sharing options...
kurahashi Posted October 29, 2006 Report Share Posted October 29, 2006 Ok, vlans are defined but the question is if the routing is (properly) configured beetween them. Link to comment Share on other sites More sharing options...
Switeck Posted October 29, 2006 Report Share Posted October 29, 2006 Is there a firewall on the server doing "stateful packet inspection"?Most such firewalls don't handle BitTorrent traffic correctly or fast enough. Link to comment Share on other sites More sharing options...
kurahashi Posted October 30, 2006 Report Share Posted October 30, 2006 Switeck, look at the IP's This server apparently doesn't do any routing, it only has an IP in every VLAN (192.168.20x.254).But the gateways are 192.168.20x.1 Link to comment Share on other sites More sharing options...
Switeck Posted October 30, 2006 Report Share Posted October 30, 2006 A firewall may be used even when routing is not done. It could even be a case of a firewall being misconfigured. Link to comment Share on other sites More sharing options...
aryx Posted November 4, 2006 Author Report Share Posted November 4, 2006 There is no firewall, the server has a .254 address in each vlan and there is no routing. The server has a "server network card" that can read vlan data. there is one port on the network card, but in windows you can see 4 network connections, one for each subnet. And those network connections are configured with a 192.168.20x.254 address.Could it be that utorrent can't send out peer information to the clients because it sends it to the wrong subnet? They can all download from the server, but they do not share data with each other. Link to comment Share on other sites More sharing options...
Switeck Posted November 4, 2006 Report Share Posted November 4, 2006 Can they "see" other peers on the same subnet at least?If not, it may be a firewall on the peers. Link to comment Share on other sites More sharing options...
aryx Posted November 4, 2006 Author Report Share Posted November 4, 2006 When every machine has startet they appear in the peers count. 1(1) Seed 0(12) Peers.As I see my answer it looks like the clients gets the needed data from the server, right? Since it can see the clients... Link to comment Share on other sites More sharing options...
aryx Posted November 8, 2006 Author Report Share Posted November 8, 2006 Any idea how I can find out what the problem is? How can I test to see if anything is blocking traffic? Can it be that the clients are listning on wrong ports? Link to comment Share on other sites More sharing options...
Switeck Posted November 8, 2006 Report Share Posted November 8, 2006 Can these computers share files between each other using windows sharing?Can these computers PING each other? Link to comment Share on other sites More sharing options...
aryx Posted November 11, 2006 Author Report Share Posted November 11, 2006 I've done some more research now, it seems like the firewall is activated during sysprep minisetup, and that is the reason why they can't share with each other.Thanks for your effort to help me solve this!
