Dreamweaver can no longer access my server via SFTP

My site's server just changed its sshd configuration to remove insecure algorithms and Dreamweaver (v18.0 on a Mac with High Sierra 10.13) can no longer access it via SFTP. It does not support FTP.  I have the list of my server's supported SSH Ciphers, Kex Algorithms and MACs.

How can I find out what ssh standards Dreamweaver supports?  Is there a way (e.g., a config file) that I can update Dreamweaver to ensure it uses one of our supported crypto standards for SFTP?

The team is aware of the limitation and is working towards updating the feature.You can share your feedback with the team using Adobe Dreamweaver CC: Feature Ideas

Meanwhile, I suggest using Filezilla.

Thanks,

Preran

Thanks.  I had reviewed that and checked everything I could think of before finding out that out sysadmin had removed some less secure standards from our sshd configuration.  So my working theory is that the problem is that Dreamweaver is using one that our server no longer supports.  Hence my desire to find out what ciphers etc. Dreamweaver uses and if there there is a way to reconfigure it.

So you work for Dreamweaver and you recommend using other software Filezilla because you cannot fix the problem. Is that correct?

February 05 and the problem still exists.

Should we all move to other software permanently?

DW is web authoring software.  It's not a dedicated sFTP or FTP client.

If your server admins decided to elevate the sFTP cipher levels on their side, that's not DW's fault is it?

In the meantime, use FileZilla or similar sFTP client that can support your new ciphers.

SFTP is integrated and integral to Dreamweaver functionality. If Adobe can't keep up with the latest security availale for their customers, then they deserve to lose their existing customers to other software developers who do.

I have used Filezilla and other web tools alongside DW for a very long time.  As I always say, use the right tool for the job.  If DW can't do what you need, use something else.

I've been using Dreamweaver for approx 20 years. Couple of ftp bugs along the way but were fixed quickly. I have many websites and now can't update any via Dreamweaver! If I have to use other programs/software to upload, then why stay with Dreamweaver?? I am paying for a premium software, if it's not running at the forefront of technology then what's the point.

I can't remember when or if DW was ever at the forefront of web technology.   IMO, it's about 2 years behind where I think it should be.   That said, I mainly use DW for site management, code hints and auto code completion features for which it excels.   FTP is fine when it works but the truth is I actually prefer Filezilla because I can do more with it.

No I won't stop recommending Filezilla because it's a superior FTP/SFTP tool to use.

Adobe please fix this problem urgently.

Feel free to submit your feature request from the DW  Help menu.   This is a user-to-user forum.  Adobe engineers don't see these posts.

Unfortunately, it's fairly likely that it's simply not urgent for the majority of DW users out there. If it were, the forum would be absolutely flooded with "my FTP doesn't work" posts. There are a few from time to time, but when an issue affects the main user-base, there will be dozens of posts about it daily.

Unless Adobe receives input from multiple users on multiple fronts about a given issue, it will be categorized below "high priority" and other problems will be taken care of first. Have you clicked the link Preran gave to make your voice heard to the dev team over in the Bug Report/Feature Request forum?

The way Adobe does things, we won't know it's fixed, until it's fixed. They don't give ETAs on anything. It's possible that it's a simple fix and it will be out in the next dot release (which would be relatively soon if the CC update cycle continues as it has). It's possible that it's a bit tougher and requires more time to get it done and doesn't make it until the next full release. We won't be told either way.

Until it is taken care of, FZ is a simple and reliable alternative to DW's FTP module.

Then try and be helpful and get a fix instead of recommending alternative software. I already know what is out there. I want to keep using Dreamweaver as I have always done.

Seeing as how DW did not create the problem, have you considered changing web hosts?

Hi,

Can you tell us to which hosting server are you trying to connect?

Also, if you could list down the whole list of ciphers, MACs and KexAlgorithms supported by your server- we could debug this issue better.

From my host, although I have already reported this info previously.

It's a standard linux server. OpenSSH.
 

Here is the connection from your side:

Feb  2 09:30:41 100023bf0000 sshd[6426]: Unable to negotiate with xxx.xx.xx.xxx port 54843: no matching MAC found. Their offer: hmac-md5,hmac-sha1,hmac-ripemd160,hmac-ripemd160@openssh.com,hmac-sha1-96,hmac-md5-96 [preauth]


Here is what the server supports currently:

KexAlgorithms curve25519-sha256@libssh.org,diffie-hellman-group-exchange-sha256
Ciphers chacha20-poly1305@openssh.com,aes256-gcm@openssh.com,aes128-gcm@openssh.com,aes256-ctr,aes192-ctr,ae...
MACs hmac-sha2-512-etm@openssh.com,hmac-sha2-256-etm@openssh.com,umac-128-etm@openssh.com,hmac-sha2-512,h...


  Basically, dreamweaver is trying to connect to the server using very old ciphers that are basically no longer secure (and haven't been for some time).

CS6 is no longer sold, supported or updated.

The free Filezilla client is a good option for FTP when legacy versions of DW won't play nice with a given server configuration.

Thanks Jon,

I was working nicely last week but WPEngine changed it SFTP configuration to requiring aes192-ctr or aes256-ctr to connect securely to its server.

I can't find any of those options in DW to configure.

And you won't because CS6 has not been updated since Dec 2012.

You would need to purchase a Creative Cloud subscription to get the latest version of DW CC 2018.   Or as Jon said above,  use a dedicated FTP Client like Filezilla.
