Hi! Thanks for lftp. A great piece of software.
We need an option to completely disable retries. The option net:max-retries = 0 unfortunately means unlimited retries. I have an issue with LFTP (Version 4.4.15) when it comes to “misbehaving” mainframe remote sites. The problem occurs when the FTP server/proxy (IBM FTP CS V1R13) fails to get exclusive permissions to the target dataset (file). The server then issues a 125 message and terminates the connection. (Which I think is incorrect behavior, but that's not the point). What happens next is that lftp reconnects again (I have net:max-retries = 1. I don’t want it to retry!) and does NOT issue the SITE commands that were in the command file, prior to the put command. This time, the FTP server does not have a problem, so lftp successfully sends the file, but it then gets the wrong record length on the remote side ☹. This is my command file: set ftp:use-feat false set dns:fatal-timeout 50 set net:max-retries 1 set cmd:fail-exit true set ftp:sync-mode true set ftp:use-site-utime false set net:connection-limit 1 open 10.0.0.2 set net:socket-bind-ipv4 172.17.0.2 site SBD=(IBM-278,ISO8859-1) site LRECL=240 site RECFM=FB put -a /var/tmp/vidare_tmp.21077.21504tina1399629722_00b996a43ed577108682 -o \'BQY0P.QY300A10.FEFI(+1)\' and the resulting log: ---- Resolving host address... ---- 1 address found: 10.0.0.2 ---- Connecting to 10.0.0.2 (10.0.0.2) port 21 <--- 220 blaha FTP Proxy, Authorized use only, use user@host to login ---> USER US00000@MVS3 <--- 331-TCPFTPD1 IBM FTP CS V1R13 at mvs3ibm.sys.bla.ha, 10:02:08 on 2014-05-09. <--- 331-Connection will close if idle for more than 5 minutes. <--- 331 Send password please. <--- 230 US00000 is logged on.

Is there a way I can disable the reconnection and instead have LFTP fail with non-zero result when the connection gets dropped? I would really appreciate that. It’s IBM on a mainframe I’m talking to. They are a bank. They don’t care that they violate the RFC. We are their only customer that has issues with this. Thanks! Mattias
