I'm having a problem with minerd not able to connect to a stratum pool behind a corporate proxy. I can connect to a different longpoll pool fine using the proxy settings but stratum+tcp fails. The same stratum settings work fine outside the Corp proxy on my other mining boxes.

Are the proxy settings only configured to work when you aren't using stratum?

You can't use Stratum with a HTTP proxy because Stratum does not operate over HTTP, but you can use a SOCKS4/5 proxy.
For further assistance, please specify the type of proxy and the exact command-line arguments you have tried.

Is it possible to add Intel Xeon Phi support (MIC architecture)?
Thanks!

If you or someone else can give me access to the hardware, I might try to give it a go.

Hi, maybe this is not a perfect thread for this, but anyway... I have a problem with connecting to mine some LTC

Not perfect? You're using cgminer and pool-x.eu. Hmm, completly wrong thread I would say. Cheesy

Anyway, your URL looks wrong - check the postion of "/".

You're definitely in the wrong thread. Ask in your pool's thread or in the thread for cgminer, and provide more info about your configuration.

then use the -u and -p for auth and the -o just without credentials

I don't have any problem with the username and password for the pool I am using, I just have a problem figuring out the correct syntax to use with the -x option for the proxy server that that particular computer is using. The proxy username is PUBLIC\*****@LibraryPublic
So you are saying it should look like:
-x http://PUBLIC\*****@LibraryPublic@***.***.***.***:8082 ?

ah right, forgot you need it for the proxy not for the pool auth. in this case there probably isnt a easy solution besides making a hardcoded proxy into minerd or running with proxychains/similiar
are you enforced to use this proxy?

OK, thanks for your help, I'll try out that configuration tomorrow.
I'm not convinced that it will work though because my username also has an @ symbol in it.

I have tried using -x http://:8082: but this doesn't work.
I need to know the correct syntax to add the user name.

I am trying to use this software on a work computer that uses a proxy, so I have addded "-x http://:8082"
The output from the terminal says "[2013-07-02 10:17:04] HTTP request failed: The requested URL returned error: 407 Proxy Authentication Required"
The proxy needs me to add a user name, which I do know.
What is the correct format to add my user name to the proxy option to make it work?

Will changing my scantime affect performance on older, slower computers?

Quote from: pooler on February 13, 2012, 01:37:23 PM

Brief note on the -s/--scantime option
I have seen people suggest various values for this option in order to reduce stales when mining in pools.
The funny thing is that, to my knowledge, all Litecoin pools have long polling permanently enabled (which is good), and when long polling is enabled the scantime parameter is completely ignored.
For this reason, the use of this parameter only makes sense when you are mining solo.

When I configure CFLAGS="-03" is says that "C cannot compile executables"

It's "-O3", not "-03". See the difference? (It's big O, not zero.)

One other question for Pooler...Will changing my scantime affect performance on older, slower computers?

Holy Crap!! That is why it always says that it cannot compile executables!

is there built in support for failover to different configurations if (eg) a p2pool node goes down, or would one need to write their own external script for that?

No native support for that at this point, sorry. See here for some sample failover scripts.
