Once downloaded the installation script you may encounter a trouble like this:
.../ssw/offline/swmaint/script/ssw_install.size: Too many arguments.
to overcome this is sufficient to insert the following lines in ".../ssw/offline/swmaint/script/ssw_install.ftpget"
and
".../ssw/offline/swmaint/script/ssw_install"
setenv SSW $HOME/ssw
setenv ssw_host sohoftp.nascom.nasa.gov
setenv ssw_sw_host sohoftp.nascom.nasa.gov
setenv ssw_tar_old_style ""
setenv ssw_sw_sets "ssw_ssw_site ssw_hinode_gen ssw_hinode_sot ssw_packages_binaries ssw_ssw_gen"
setenv ssw_db_sets ""
setenv ssw_passive_ftp 1
setenv ssw_noepsv
setenv ssw_skip_sizechk 1
Now from shell run manually these two scripts:
csh -f .../ssw_install.ftpget
and
csh -f .../ssw_install
Now your installation should be ok!
