How do I make my client acquire more than 8 connections? What settings in firewall and operating system, or flags at execution do I need to use to allow it?

1Could you possibly expand on this question to make it less specific? This has nothing to do with ubuntu or scripts.– Evil SporkSep 3 '11 at 19:54

@Evil I understand your concern. I haven't devised a clever way to do that though.– Jader DiasSep 4 '11 at 1:51

I edited it, though since I do not yet have editing permissions, others need to approve it.– Evil SporkSep 4 '11 at 2:04

Typically connection counts of 10 or lower usually indicate that you are behind a router or firewall that is not configured properly. Try enabling UPnP from within the Bitcoin client's options dialog. If that doesn't work, try manually forwarding port 8333 to the computer which is running the Bitcoin client/daemon.

You're right. The UPnP was activated by default but not working. The router was forwarding to an old IP address, and I fixed it by reseting it, so nothing changed on the PC. Sep 2 '11 at 22:14

2The outbound connection limit is exactly 8, the inbound connections are only limited by the
-maxconnectionstotal which is usually 125 (version 0.3.25). Sep 2 '11 at 22:21 -
1Thanks! It helped me realize my router had UPnP off. *facepalm– user173Sep 3 '11 at 7:15

2@EvilSpork is right. For easiest solution use UPnp. For the manual but much safer solution use port forwarding. Also having open inbound connection port (eithe manual or uPnp) also makes the rest of the network stronger. Firewalled clients can only receive connections from non-firealled clients so your open inbond port improves the connection access of nearby firewalled clients. Oct 17 '11 at 13:03

1One thing I would add is that only one client on a network subnet (your home LAN) needs inbound connection. The clients are "smart" enough to look for peers on local network first so if one client on your home LAN gets a new transaction it will be relayed to all other clients on the LAN.

A)
To disable the half-open TCP connections limit, set the value of the
EnableConnectionRateLimiting DWORD registry entry to 0 (0x00000000). To do this, follow these steps:1. Click Start, type regedit in the Start Search box, and then click regedit.exe in the Programs list. If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
- Locate and then double-click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
\EnableConnectionRateLimiting
In the Value data box, type 0, and then click OK.
Exit Registry Editor.
5. Restart the computer.
B) Open the command prompt and use the following opening switches, alternatively you could plug the switches into the properties of your exec. shortcut.
