[BioC] GEOquery not working, NCBI changes?

[Gad Abraham]

Hi,

I'm having trouble getting GEOquery to work recently.

On Ubuntu 9.10/R-2.10.1/BioC 2.6.1, GEOquery 2.11.3, download.file
stops with "cannot open URL",
On Ubuntu 8.04.1/R-2.9.2/BioC 2.4.1, GEOquery 2.8.0, curlPerform stops
with "Server denied you to change to the given directory"

wget downloads the file fine, but requires PASV which download.file()
doesn't support
(http://tolstoy.newcastle.edu.au/R/e6/help/09/01/0969.html)

I suspect that NCBI has changes some server settings, is this a known issue?

Thanks,
Gad
