Hi experts,

I had installed lftp package to my server ,, How i need to test whether my server capable of SSL? and how to test
Vadim RappCommented:
I would start with simply trying the session with Master Server, since this is the final purpose. Or you can grab any SSL-capable client listed at, for example CoreFTP, and try to connect to your server by SSL.
Vadim RappCommented:
Here's an example of the FTP over SSL session log. The server is of course different since I don't haev AIX, but the FTP should be the same. I have highlighted the pieces that tell that it's indeed secure session.

Hi vadimarapp,

Thanks for all your support. Still i am facing some file dependence error. However i installed all the require libstdc++  rpm files.

# lftp
exec(): 0509-036 Cannot load program lftp because of the following errors:
        0509-150   Dependent module libstdc++.a( could not be loaded.
        0509-022 Cannot load module libstdc++.a(
        0509-026 System error: A file or directory in the path name does not exist.
Vadim RappCommented:
Sorry, can't help in this, since have no idea about neither Unix, nor C.
you need to add /usr/local/lib to LIBPATH in /etc/profile

Hi vadimrapp1,

Good morning !

Update: Successfully installed lftp on AIX 5.3 as clinet. Now i need to ensure how SSL connection establishing !  i am able to connect to remote ftp server . But i need evidence? How ? where i can find lftp log file , where u got FTP over SSL session log (in above post)

Vadim RappCommented:
In my post, I used windows-based client, totally different, and only as an example of what to look for. Presumably, your lftp also produces some log, like every ftp client does, and that's where you will find the lines similar to my example. You will probably find out where the log is created in the documentation on lftp.
MaddyUNIXAuthor Commented:
its not solved my purpose
Where is the problem? Did you fix the LIBPATH?
Vadim RappCommented:
Probably for the two months, the purpose has changed sufficiently from "Successfully installed lftp on AIX 5.3 as clinet" to "its not solved my purpose" to suggest C grade.
Question has a verified solution.
