Hello, I am having trouble getting the curlPerform function to authenticate using the .netrc file. From the documentation I've read it certainly seems as though this function should be able to authenticate via the .netrc file. The example I am using here comes from the "R as a Web Client- the RCurl package" paper and demonstrates using the .netrc file to access the

Hi, I have two accounts with broadvoice. Now, I want to be able to distinguish between them. I though that this would be simple by adding "/EXTEN" at the end of the register statement. For example: register => num1:pass@sip.broadvoice.com/1000 Unfortunately, this is not working. When I call into my box I hear busy tone. My config looks like this: [root@voip asterisk]# cat sip.conf

I expect that when I do > lapply(vec,f) f would be called _once_ for each component of vec. this is not what I see: parse.num <- function (s) { cat("parse.num1\n"); str(s) s

Hi: The sysadmin on the system where the icecast server I more or less administer runs sent me an E-mail today saying that icecast had pushed up the system load to over 8 and that he had to kill it off. Some discussion and examination of the log files suggest that there's a problem with removing streams from the YP server. The main source on our server is on a machine that's used for
