In most wallets you can increase it with command line options or with the wallet .conf file.
Code:
-maxconnections=<n>    "Maintain at most <n> connections to peers (default: 125)"
-maxoutbound=<n>       "Maintain at most <n> outbound connections to peers (default: 8)"

With more connections you can reach the whole network with less hops. And it might help finding less orphans. Not sure.
Also, with more connections you can download the blockchain faster (if you're not CPU and/or IO bottlenecked, which is generally the case).

The reason I asked because I solomined YAC for days and found nothing, not even an orphan block and I just recently increased the active connection limit and was not sure that it would have any connection between solomining. I guess it doesn't.

Ah, so this isn't about RPC connections of miners to the wallet...

I think in all the time mining YAC (2 weeks or so) I had just a single orphan.

The YAC network doesn't seem particulary loaded with traffic, so I think 8 connections are just fine.

By the way the Windows Yacoin wallet reports 15 active connections, and my Linux wallet (which is the one I am solo mining with) reports 8 connections. Both are at v0.4.2.

Transactions must be included in a block to be properly completed. When you send a transaction, it is broadcast to miners. Miners can then optionally include it in their next blocks. Miners will be more inclined to include your transaction if it has a higher transaction fee.

-H 2 in scrypt-jane now puts keccak onto the GPU. However the CUDA kernel is still a perfect example of how NOT to do efficient CUDA code.
Meaning without further optimizations, don't expect any miracles yet!

EDIT: seems my 660Ti could do around 400 kHash/s Keccak alone (when I remove the ROMix phase of scrypt). This is about 10 times the performance I had with the CPU based Keccak (single core used). What I do not understand however is why the CPU use of that cudaminer instance still hovers around 15%... It should be idling!

Is there any way to set up Cudaminer to have a failover / backup server if one goes down? Cgminer allows you to edit that in the config but there isn't a config file for cudaminer. Is there any way to set it up with the .bat?

Something like this from cgminer??

I think a good way to make this possible is with a --shutdown parameter, which would make cudaminer shutdown as soon as it has a connect failure.

Why would I want it to shut down? I just want it to switch to another server if it disconnects and is unable to reconnect. Eventually, I'd like it to go back to the original server when it's up again.  Huh

Stanr010, the shutdown would allow an external script or control software to manage the failover process...

please watch the volume of quotations (> 80% in your posting)

Failover is on my TODO list. But right now I am completing the scrypt-jane feature.

Not for YAC, but maybe people can now start to try mining somewhat lower Nfactor coins.

I believe I can still make that Keccak GPU code 50 times faster. What you see is just the first working draft.

I believe it's still spending 3/4 of the GPU time in the Keccak code. Otherwise you would
be seeing the indicated 2303.87 khash/s instead of "only" 530...Wink Maybe in a day or two I've
got the speedup you need.

I downloaded a MicroCoin wallet. Donations go here please: 1Lxc4JPDpQRJB8BN4YwhmSQ3Rcu8gjj2Kd

Meh... wallet doesn't sync. initially it shows 2 connections. After a minute they drop to 0.

Not a small sum agreed.. But cbuchner1 is worthy of such an award - he deserved it. I think we all need to financially support such an important job.
