Firewall Detection At start up Limewire detects my routers firewall then after about half an hour the firewall icon disappears and the port is open and not reported as closed even if port 6346 is reported as closed I can still upload at a good rate what I am saying is that Limewire opens up a lot of ports on my routers SPI firewall which are not used by Gnutella at all |
After I run Limewire it opens up all my ports that were reported as closed leaving them wide open then after I'm done with my transfers and close limwire they go back to closed |
So, what's the problem? That's what LimeWire's supposed to do -- it's LimeWire using UPnP to configure itself for optimal use. If you really don't want it, go to Tools -> Options, Advanced -> Firewall Config, and change the option to "Do Nothing". |
yeah I know that but more then port 6346 becomes open |
6346 is the Gnutella port. What else opens? |
1125 1126 144 4933 6348 4638 those are the ports that are currently open while running LW earlier today there were even more open I'm not sure what associated ports LW runs on I was thking LW only runs on port 6346 |
You did get Limewire from the official website http://www.limewire.com , right? There should be nothing besides 6346 open. |
yes I got limewire pro from liemwire.com |
How did you determine that those other ports were opened? |
I used a few web sites that do port scans and took a look around my windows a bit but it doesn't seem to happen 100 percent of the time that I am using LW I was checking to see if other ports were open because of the new firewall icon displayed on LW inspired me to look into that a little further which I normally do a security check from time to time |
That kind of check isn't 100% correct. Routers open up ports all the time in response to simply using it. The way connections work is that when a program makes an outgoing one, it uses what's called an "ephemeral port", that is, a random port. Routers generally open up those ports for incoming access. |
all right thanks I'll still keep checking tho |
Please forgive me I am brand new to networking and was concerned about computers running on my home network and any security issuers that might arise from using LW on my network |
if you REALLY would like a detail look at whats opening ports.. do this: start > run > cmd.exe <enter> now type in the black dos window: netstat -a -b -v now it should look like this: Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp. C:\Documents and Settings\*your account*>netstat -a -b -v Proto Local Address Foreign Address State PID TCP NETWORK-93BA05E:http NETWORK-93BA05E:0 LISTENING 2000 [Apache.exe] TCP NETWORK-93BA05E:epmap NETWORK-93BA05E:0 LISTENING 1100 c:\windows\system32\WS2_32.dll C:\WINDOWS\system32\RPCRT4.dll c:\windows\system32\rpcss.dll C:\WINDOWS\system32\svchost.exe -- unknown component(s) -- [svchost.exe] TCP NETWORK-93BA05E:microsoft-ds NETWORK-93BA05E:0 LISTENING ...etc if you dont want it to resolve hosts, or use names of ports, just use the -n option, this forces the numerical option which makes everything has a name back into its number form: C:\Documents and Settings\*your account*>netstat -a -b -v -n Active Connections Proto Local Address Foreign Address State PID TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 2000 [Apache.exe] this will give you LOTS of stats on what programs and services have activated a port. if you want to know what is being sent over these ports, download ethereal and its required winpcap ethernet library at http://ethereal.com/ you can learn some interesting things about networks by just sniffing ;) |
thank you |
