WS-FTP unable to connect to server after software update
I have a bit of an authentication problem. I updated some packages on my Slackware64 14.1 system yesterday. Today, when a client was trying to WS-FTP to his account, he was blocked. The WS-FTP log is below. I've tried restarting openSSH. I can ssh to this account, but the client cannot WS-FTP. I'm sure it has something to do with the update, but I don't have any idea where to look. Need help

Hmmm, I'm probably not going to get them to do that. Is there a way to change something on my end?

I think you need more info. What FTP client works form your computer? Have you tried WS-FTP on your computer? Note that older algorithms and methods are being 'expired' all over the web. They may not have a choice.

Yes, I know, I've run into this before. I've asked the fellow to check on updating his WS-FTP.
I am able to sftp from a remote linux host, no problem. I don't have access to WS-FTP.
I'm wondering if I can somehow specify an older encryption mechanism in a configuration on my Linux server.
