Unfortunately Solaris does not come with a ftps compatible client by default, but you can get round this by either a) installing another client such as lftp or b) using CURL
CURL is not a super friendly program however, so here are some of my notes on using it to access one of my servers.
Get a directory listing of the files in the source directory
curl -k -3 --ftp-ssl -u techie ftp://files.blah.com:990//export/home/sources/* -l
-k says to ignore certificate problems (this may be bad in the outside world – but this is all internal to my network and we don’t have ssl certificates)
-u specifies the username to connect to the server. You can optionally follow this with a : and a password -u username:password but this will be clear text. If you don’t specify a password on the command line it will prompt. Another option is to use a curl config file (–config with the username:password specified in it)
-3 says to use SSLv3 (this may not be relevant in your environment)
// in the directory path says that it is an absolute path not a relative one.
This will give you a list of the files inside the directory, which is super handy for scripting purposes.
Then you can issue curl command for each file you need to download like
curl -k -3 --ftp-ssl -u techie ftp://files.blah.com:990//export/home/sources/myfile.txt -O
-O specifies to create the file in your local directory, with the same filename.
Curl has a whole bunch of options and this is only a tiny snapshot. There is a really useful man page available online at http://curl.haxx.se/docs/manpage.html
