Special Forums IP Networking Help determining what's blocking ports Post 302266403 by sysgate on Wednesday 10th of December 2008 05:29:37 AM

With no meaning to be offensive or rude, but :"I was recently assigned to be network administrator where I work" - the network admins I know have at least two certifications and many years of studying, practicing, etc. Being a netadmin is a bit different from being sysadmin or a programmer, so my point is that this reassignment doesn't speak good for your employer. But since you're in the jam already, let's try to help you.
You say that you can't get utorrent to work, usually torrent clients require some ports opened for P2P communication. There are lot of devices mentioned in your post - do you have access to all of them, for example to check any ACLs, firewalls ? Start with a simple telnet session probe to the destination IP, as in :
Code:
telnet 10.101.3.5 2054

- check the response and let us know, certainly, replace the respective IP address and port number. For port scanning, you can consider using nmap.

NAME
aseqnet - ALSA sequencer connectors over network SYNOPSIS
aseqnet [remotehost] DESCRIPTION
aseqnet is an ALSA sequencer client which sends and receives event packets over network. Suppose two hosts connected by network, hostA as a server and hostB as a client. The ALSA sequencer system must be running on both hosts. For creating the server port, run the following on hostA: hostA% aseqnet sequencer opened: 128:0 Then a user client 128 with port 0 was opened on hostA. (The client number may vary.) For creating the (network-)client port, run aseqnet with the hostname of the server: hostB% aseqnet hostA sequencer opened: 132:0 Now all events sent to hostA:128:0 are transferred to hostB:132:0, and vice versa. The ports created by aseqnet can be connected arbitrary to other sequencer ports via aconnect(1). For example, to connect hostB:132:0 to a MIDI output device 65:0: hostB% aconnect 132:0 65:0 Then events to hostA:128:0 will be delivered to hostB:65:0. The following command plays MIDI on hostB. hostA% pmidi -p 128:0 foo.mid The multiple clients may exist simultaneously. If hostC is connected as a client to hostA, events from from hostA are sent to all con- nected network clients, i.e. hostB and hostC. However, only one connection is allowed from a client to a server. To disconnect network, stop all clients before server by ctrl-C or sending signal to them. The server will automatically quit. OPTIONS
-p port Specify the TCP port number or TCP service name. -s addr Subscribe to the given address for read automatically. -d addr Subscribe to the given address for write automatically. -v Verbose mode. SEE ALSO
