I use dolphin on a ArchLinux client to connect to a Gentoo sshd server to serve files. I connect like so in dolphins adress bar: sftp://kai@black.landsberger.poeritz.de/home/kai/data/ Dolphin errors out and sais: Unable to request the SFTP subsystem. Make sure SFTP is enabled on the server. in a red bar right below the adress bar. This ONLY occures when I connect an ArchLinux based client to a gentoo based sshd. archlinux-client -> gentoo-sshd : FAIL gentoo-client -> gentoo-sshd : OK archlinux-client -> archlinux-sshd : OK All systems are up to date I tested other methos like "fish" for "sftp" and also command line sftp. All of these work fine. Also, before the recent KDE update "archlinux-client -> gentoo-sshd" used to work as well. So I suspect dolphin in its newest version to cause this. Reproducible: Always Steps to Reproduce: 1. sftp://user@your-gentoo-based-sshd:/ Actual Results: I get the error message: Unable to request the SFTP subsystem. Make sure SFTP is enabled on the server. Expected Results: I should be presented my remote fs.
Created attachment 85956 [details] See how it fails on the left, but works on the right an bottom
Thanks for the bug report! This is a bug in KIO, I'll reassign it.
The sshd on the gentoo server is: OpenSSH_6.6p1-hpn14v4, OpenSSL 1.0.1f 6 Jan 2014 The ArchLinux client gets updated on a daily basis. And prior versions of dolphin/KIO used to work just fine
Thanks for the bug report, but please provide detailed information: http://techbase.kde.org/Development/Tutorials/Debugging/Debugging_IOSlaves/Debugging_kio_sftp

I can confirm this happening for me too, also from Arch. dolphin 18.12.0-1 libssh 0.8.5-1 (both client and server) libssh2 1.8.0-3 (both client and server) openssh-hpn-git 7.5.P1.r74.ga0c37a72-2 (server) /etc/ssh/sshd_config https://pastebin.com/F0JzfnBQ SSH (fish://) works, sftp does not (both with the main user and the sftp chroot user called readonly). I have tried following https://techbase.kde.org/Development/Tutorials/Debugging/Debugging_IOSlaves/Debugging_kio_sftp#Logging but I get no output, even after running kdeinit5
This works if using openssh 7.9p1-1 instead of openssh-hpn-git 7.5.P1.r74.ga0c37a72-2 on the server
This could be related to: https://git.libssh.org/projects/libssh.git/commit/?h=stable-0.8&id=a6e055c42b34ec50f55606312b09ec2e14990416
I think this has been fixed in libssh.
