Dear R-help, I've been compiling R from source on our Linux boxes for quite a while. One thing that bugs me is that I always get an error when make check-all where it choked up running tests/internet.R. That wasn't a big deal, as I can run install.packages()/update.packages() fine, and that's all I use the 'net connection for. The problem is that it takes a _long_ time to fail internet.R. I dug in just a bit more this time (that I was sufficiently annoyed). The problem is:> read.table("ftp://ftp.stats.ox.ac.uk/pub/datasets/csb/ch11b.dat")Error in file(file, "r") : unable to open connection I tried running the line in an interactive R session, and sure enough, it takes more than 10 minutes before I see the error. I do have both HTTP and FTP proxy set (to the same URL), and ftp (e.g., to CRAN) works outside of R. Can anyone provide some hints as to what the problem might be, or where to look?

Can you open a url() connection? Works for me within a second on both Windows and Linux.
