ftp proxy sometimes does not work

[FumioKishida]

hi i am using f5 ftp proxy "big-ip"

i made a ftp batch file like follows:

ftp "-s:test.txt"

test.txt:

open proxy.xxx.com
user1@destination.xxx.com
passwd1
ascii
get /logfiles/todaylog.txt
quit

but the above script sometimes does not work.

is the "s option" not supported in f5 ftp proxy?

The F5 never received the -s option. That is a client option, used by the FTP program you are using. The F5 would only receive the commands in the file they the client is parsing using that option.

If you are "sometimes" seeing uses, is that with different users attempting to FTP? How is the FTP profile and any persistence configured?
