We had a similar problem and found it was related to port 113 and firewalls. We had the ftp server on a Linux box and were using the client from z/OS. We ended up creating a rule to keep the Linux ftp server from sending to port 113 of the client. Port 113 has something to do with identd.

If I do the same FTP transfer to a Windows server I got a transfer rate of about 900K/sec. The mainframe OSA card is running at 100 Mb/sec full. Since the Windows and the LINUX server are on the same switch and got the same throughput capability I suppose that there is an optimal setting that is done automatically when the transfer is done with a Windows server but this setting is not done automatically with a LINUX server. I tried PASV but it didn't change the bad transfer rate. Could you tell me what this setting could be? Thank you! ************************************************************ Francois Pare Universite Laval Service de l'informatique et des telecommunications 1055 avenue du Séminaire Pavillon Louis-Jacques-Casault Quebec (Quebec) Canada G1V 0A6 tel.: 418-656-2131 ext. 4013 fax: 418-656-7305 ************************************************************ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
