This is my logs for vsftpd.
I am not able to troubleshoot why the error "426 Failure reading network stream." is comming.
What are the possible reasons for this error?

!!!THANX!!!

What client are you using?

Are you able to ping without any lose or really high times?

Have you tried using PASV mode as suggested in the logs?

I dont know the ftp client. Because users are uploading the files from remote site. How it can be a problem of ftp client?

We are using the passive mode only.

Pinging is also ok.

I'm not sure if it's related since your error says reading, rather than writing, but the VSFTPD FAQ has this:

Code:

Q) Help! I'm getting the error "426 Failure writing network stream." on downloads.

A) You shouldn't see this with v1.2.1 or newer versions of vsftpd. Older

versions of vsftpd can give this error if the user tries to download

something from an unusual filesystem (e.g. FAT), which don't support

performance features used by vsftpd. With vsftpd-1.1.3 and newer there is a

config workaround, use_sendfile=NO.

But my vsftpd version is 2.0.1-5.EL4.5

I know this is an old post, but did you ever figure out what was going on? I'm having the same issue.
