Hi everyone, :)
Now that I'm comfortable with interfacing with Kermit from glftpd and connecting
to other encrypted FTP-servers, I have started looking at the more important
features requested, like file transfers.
I just recieved a late request for using site-to-site transfers. :/
The reason is, that glftpd maintains indexes (which the SITE SEARCH command
uses), and statistics for all transferred traffic.
If I insert files into the local FTP-folders by other means than using the
actual FTP-server, the server would need periodic reindexing, and traffic
statistics would become incorrect.
If available, I would like to use the site-to-site method, by establishing
control-sessions to both FTP-servers, and instructing them to send files between
eachother.
This is mentioned in RFC959, section 3.2:
"It is possible for the user to specify an alternate data port by
use of the PORT command. The user may want a file dumped on a TAC
line printer or retrieved from a third party host. In the latter
case, the user-PI sets up control connections with both
server-PI's. One server is then told (by an FTP command) to
"listen" for a connection which the other will initiate. The
user-PI sends one server-PI a PORT command indicating the data
port of the other. Finally, both are sent the appropriate
transfer commands."
Is this feature available in C-Kermit?
If not, I'll have to collect files from the remote hosts to a local temp folder,
and then do a second session against localhost to insert the files into the
local site.
Not a biggie, but if I could avoid it, I would. :)
