RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Sample Text file
Description of problem: FTP is timing out when trying to transfer a text file via a client like FileZilla or WinScp.
The FTP only times out for a text file in a certain format. The sample file is attached.
If any changes are made - for example the attached file contains 311 characters and if the number of characters is reduced to 310 or below the file gets transferred successfully.
Another example is if any changes to the word 'list' is made like removing a letter or changing a letter in the the word then the file gets transferred successfully
The file also gets transffered successfully if the space between the words 'xxxx list' or 'list xxxxxxxxxx...a' is removed
The FTP only times out when the attempt is made without any encryption however the FTP is successful when TSL/SSL encryption is chosen in the client like WinScp
Version-Release number of selected component (if applicable): vsFTPd 3.0.2
How reproducible: Always reproducible with the file format attached with this bug
Steps to Reproduce:
1.Attempt to FTP(without encryption) the attached text file from a windows
machine using a client like WinScp or Filezilla to a Red Hat linux server(7.4)
Actual results: The FTP times out
Expected results: Must be transferred successfully to the Linux server
Thanks for the report. Unfortunately, I was not able to reproduce the problem with Windows 10 and the latest FileZilla, nor with WinSCP. I used vsftpd-3.0.2-22.el7.x86_64.
What exact vsftpd version are you using (rpm -q vsftpd)? Can you provide your vsftpd configuration? What transfer mode are you using, ASCII or binary? Are you using the latest version of Windows and the FTP client programs? Can you reproduce the problem with some Linux client, instead of Windows?
Thanks.
Hi ,
The vsftpd version used is vsftpd-3.0.2-22.el7.x86_64.
The transfer mode selected in winscp was default.
The OS used is Windows 7.
The issue cannot be reproduced on the ftp client and happens only for Filezilla and Winscp
Thanks
Antony
