I hope this isn't off-topic by too much. If it is, a word to me privately and I'll wait for responses to queries I've made elsewhere. I maintain two FTP servers and support four Windows-based FTP clients for users of those servers--FTP Voyager, FlashFXP, Filezilla, and WinSCP. One server accepts a

I decided to put the two logs from `sshd -d' side-by-side to try to figure out where the differences are. Both logs have the following lines immediately after the connection request: debug1: Client protocol version 2.0; client software version FTP-Voyager-15.2.0.15 debug1: no match: FTP-Voyager-15

More info. I used getenforce' and found SELinux is installed but disabled on the system where FTP Voyager can connect using SFTP over ssh, and not installed at all on the system where FTP Voyager cannot connect. In fact, using either the `getenforce' or `'sestatus' on the no-connect system yields `

The problem is that the older client doesn't support ciphers newer than CBC and arcfour (both depreciated on the newer server versions of OpenSSH). Lookup how to re-enable these suites using the Cipher directive.

It helps to explain things, Daniel, but truly, the client in question is horrendously out of date and deprecated for all secure intents and purposes, I'm quite happy to retire it from active support on my server. On Sat, 16 Jan 2016 15:19:33 -0300, you wrote: >Hi, Steve. > >On 14/01/16 13:10, Ste
