Bugs fixed in CIAO 4.10

The following is a list of bugs that were fixed in the CIAO 4.10 software release.

Connection timed out

The CXC retired the cdaftp.cfa.harvard.edu FTP server in the summer of 2017. It was replaced with cda.cfa.harvard.edu. Old versions of the download_chandra_obsid script try to use the old URL, and will eventually fail with a time-out error message:

# download_chandra_obsid (version): ERROR [Errno 110] Connection timed out

Workaround:

The fix for this was introduced in the CIAO 4.9.3 (May 2017) scripts release. Users are encourage to update to the latest version.

Users who cannot upgrade to the latest version may use the mirror site functionality to override the Chandra archive FTP site URL. Users can supply the -m|--mirror flag

unix% download_chandra_obsid --mirror=ftp://cda.cfa.harvard.edu/pub

Or can set the CDA_MIRROR_SITE environment variable

(tcsh) setenv CDA_MIRROR_SITE ftp://cda.cfa.harvard.edu/pub

(bash) export CDA_MIRROR_SITE=ftp://cda.cfa.harvard.edu/pub
