openssh banners not displayed

[hirschma]

Login Banners displayed by the openssh sftp-server are
not displayed in the Filezilla client.

From my sshd_config:

Banner /etc/ssh/sshd-banner

The referenced banner displays when ssh'ing into the
server, and when using the sftp command from console as
well. Filezilla, however, seems to strip such banners out.

Does the banner get displayed if using psftp from PuTTY?

[hirschma]

Yes, psftp from PuTTY works 100%.

[Alexander Schuch]

Can you please try again with most recent version of FileZilla 2 or preferably even FileZilla 3 (beta)?

Furthermore, "man 5 sshd_config" says regarding "Banner" option: "This option is only available for protocol version 2." Maybe that could help?

I see this issue. I can also reproduce with putty and sftp on a linux box. I am connecting to an openssh 1.0.0d server that is protocol 2 only.

to clarify I can produce the correct result (banner seen) on psftp (putty) on the same windows host. I can also see the correct result using an sftp client from a linux box.

[Peter Duffy]

We're also experiencing this problem (filezilla 3.7.3) - it's a major issue for us, as we need to display a banner warning that the system is private and monitored. Basically, it means that at present we can't use filezilla.

Is anyone working on this issue?

[mike latessa]

Any plans to fix this bug? Banner works with alternative clients like WinSCP

Some Notes :

Putty is showing the banner correctly.
But the banner is showing only after the login is entered (see below)

There's a putty configuration option to control if putty displays the banner or not "ssh_show_banner"

Triage suggestion

I have set up a Linux VM and can confirm that psftp and putty will display the login banner over SSH and SFTP. It appears that FileZilla Client doesn't display the login banner. Based on what I'm seeing in version 3.26.1 it appears that this is not a bug -- login banners appear to not be implemented. I'm changing the ticket type to "Feature request" as a result.

However, I suggest closing this ticket as "rejected" for lack of movement.

[Tim Kosse]

Login banners have no semantic meaning, the protocol does not require that they be displayed.
