Although I have installed R many times on many machines without problems,
I have recently encountered a problem with accessing packages. R has been
installed successfully with the "--internet2" option. The session info is
below.

R version 2.8.1 (2008-12-22)
i386-pc-mingw32
locale:
LC_COLLATE=English_United States.1252;LC_CTYPE=English_United
States.1252;LC_MONETARY=English_United

attached base packages:
[1] stats graphics grDevices utils datasets methods base
loaded via a namespace (and not attached):
[1] tools_2.8.1

When I try to load a package ("chron" in this example) from the CMU
mirror, I get the following error message:
> utils:::menuInstallPkgs()
--- Please select a CRAN mirror for use in this session ---
trying URL
'http://lib.stat.cmu.edu/R/CRAN/bin/windows/contrib/2.8/chron_2.3-28.zip'
Error in download.file(url, destfile, method, mode = "wb", ...) :
cannot open URL
'http://lib.stat.cmu.edu/R/CRAN/bin/windows/contrib/2.8/chron_2.3-28.zip'
In addition: Warning message:
In download.file(url, destfile, method, mode = "wb", ...) :
cannot open: HTTP status was '403 Forbidden (Blocked by NG)'
Warning in download.packages(p0, destdir = tmpd, available = available, :
download of package 'chron' failed
This error applies to ANY package. The option --internet2 must be used. If
not, then I cannot even access the mirror. Can anyone help me out? Could
this be a firewall problem?
