Data transfer

O'lnes — Tue, 18 Jun 2002 11:31:00 GMT

We are running UNIX platform, and use both telnet programs : Reflection and Netterm in the client side, can someone suggest what protocol (eg. Kermit ) that best suit for use to data transfer in our case? what protocol work fine in both these two programs ? Thank a lot.

andy,

from your PC, in a command window (ms-dos), use ftp

cd \directory to send or receive files in

ftp UNIXHOSTNAME
UNIX_USERNAME
UNIX_PASSWORD
get filename

or

put filename

Also, you might want to use the "bin" option to allow binary file transfers.

On the PC do "ftp -H" to get command line help, and for commands within ftp type in help (after starting ftp)

on unix, type in "man ftp"

This may or may not help (I'm no expert on this) I think SSH can be used to do rcp like stuff...

You can write ftp scripts

You said you currently TELNET into the unix boxes, which means YOU HAVE a LOGIN.

It's a LOT easier if you set up FTP on your unix server than installing special programs on all of your client PC's that need to transfer data!

Hello,

I apologize in advance if I'm not understanding when you state "requires setup ftp server and login". You don't need to "set up" an FTP server; your server is an FTP server.

Please elaborate.

On your unix box do this:

grep ftp /etc/services /etc/inetd.conf | grep -v "\:#"

which should produce something like this:

/etc/services:ftp-data 20/tcp # File Transfer Protocol (Data)
/etc/services:ftp 21/tcp # File Transfer Protocol (Control)
/etc/services:tftp 69/udp # Trivial File Transfer Protocol
/etc/services:sftp 115/tcp # Simple File Transfer Protocol
/etc/services:bftp 152/tcp # Background File Transfer Protocol
/etc/services:ftp-ftam 8868/tcp # FTP->FTAM Gateway
/etc/inetd.conf:ftp stream tcp nowait root /usr/lbin/ftpd ftpd -lLio
/etc/inetd.conf:tftp dgram udp wait root /usr/lbin/tftpd tftpd

then check /etc/ftpd/ftpaccess, if it doesn't exist, then you are ready to to use FTP without any further ado.

i want the download/upload tools called by the program, ( I mean the tools is in our application program so it is not possible to use ftp).
Any suggestion?

Reflection has a very nice graphical ftp client program and depending on how new it is, Reflection may also have an ftp server for the PC. Standard HP-UX comes out of the box with ftp and every Windows-based PC also has ftp as a simple DOS comand.

rcp requires special services to be setup for authentication and is also available in the Reflection software package. However, rcp is much slower and creates a bigger network load than ftp (lots of small packets going both ways). FTP is an adaptive protocol in several ways. For slow speed links, it makes changes to insure reliable data transfers and for high speed links, uses the maximum packets size. And in all cases, FTP allows multiple records to be transferred before requiring an acknowledgement, all of this to maximize throughput. FTP is also the only protocol that translates ASCII files, a big requirement when trying to integrate unrelated operating systems (like Windows and Unix).

What application program? ==>

"i want the download/upload tools called by the program, ( I mean the tools is in our application program so it is not possible to use ftp).

You can install perl on your PC's:

http://www.cpan.org/ports/index.html#win32

and then load the FTP module and have at it!

If you are using netterm, netterm has zmodem protocol available. You can get the HPUX side of zmodem from the software porting and archive center.

Then you can send escape sequences down to your netterm session that can begin the transfer.

Reflections includes the ftp client. Just set up the client to login, choose transfer method (ascii/binary/tenex/smart), then choose files to transfer.
