SSH MOD Dwarf

[LievenDV]

don’t forget to change the connection mode in the settings when trying windows (can’t find screenshot of exact name)

[broupe]

connection mode = SFTP
…isn’t it?

“…change the connection mode in the settings…”
…to what?

[LievenDV]

@broupe

Everything with my MOD Dwarf is 100% functional.
except SSH

Sorry
missed this.

Assuming this included succesfully accessing and using the web interface on Windows as well, my reply is irrelevant

[broupe]

still grateful

[Rom]

It seems for me you did everything right… @jon ?

@broupe

Now I have a new MOD Dwarf, and it does not work…

I suspect this is your issue. SSH keeps fingerprints for each known host in ~/.ssh/known_hosts. The fingerprint from the new dwarf will not match the fingerprint from your old dwarf. You can remove an entry using the command outlined here.

[broupe]

removed the host, and got this, very promising:

but sadly it did not work:

[jon]

I must be honest, I have no experience with that software. But, considering that you can access the WebGUI on the same machine, I would say that something is wrong on the software side.

Also, have you tried to access via Terminal?

[broupe]

You can remove an entry using
[the command outlined here
(https://developerinsider.co/how-to-remove-known-ssh-host/).

did that in Terminal

• got this reply:

1. Host 196.168.51.1 not found in /Users/bjarneroupe/.ssh/known_hosts

2. however…:
   /Users/bjarneroupe/.ssh/known_hosts

192.168.51.1 ecdsa-sha2-nistp256
moddwarf.local ecdsa-sha2-nistp256

same laptop - same MOD Dwarf

You can remove an entry using
[the command outlined here
(https://developerinsider.co/how-to-remove-known-ssh-host/).

did that earlier in Terminal

• got this reply:

1. Host 196.168.51.1 not found in /Users/bjarneroupe/.ssh/known_hosts

2. however…:
   /Users/bjarneroupe/.ssh/known_hosts

192.168.51.1 ecdsa-sha2-nistp256
moddwarf.local ecdsa-sha2-nistp256

same laptop - same MOD Dwarf …

[broupe]

in Terminal getting closer…

• maybe I got the syntax wrong in my prompt ?
  (the “hvcc-Freezer.lv2” part of the sentence)

[root@moddwarf ~]# scp -rp hvcc-Freezer.lv2 root@192.168.51.1:/root/.lv2

Inside Dwarf, but still not quite there… SFTP subsystem?

• Termius log:
  Connecting to “192.168.51.1” port “22”

  Host “moddwarf.local”:“22” is known and matches

I see a similar behaviour with my Dwarf: using Windows, everything is file (i can connect using putty or WinSCP), but using a virtual machine running Ubuntu (hosted by the same windows pc) I am only able to access via ssh.

[plutek]

a couple of years ago, i found it was impossible to do scp file transfers with a Dwarf unless i used the -O parameter.

see here: Scp problem

…your final error message, above, seems eerily like my error message: “subsystem request failed on channel 0”.

dunno if this is related or provides any useful clues?? perhaps @falkTX can shed some light, as he did for my issue.

@plutek

Scp problem

Thanks!
…tried it, didn’t work…

bjarneroupe@MacBookAir ~ % scp -rp -0 Users/bjarneroupe/Downloads/hvcc-Freezer.lv2 root@192.168.51.1:/root/.lv2
scp: illegal option – 0
bjarneroupe@MacBookAir ~ %

tried again:
scp -rp /Users/bjarneroupe/Downloads/hvcc-Freezer.lv2.zip root@192.168.51.1:/root/.lv2
subsystem request failed on channel 0
scp: Connection closed

[plutek]

@broupe

scp: illegal option – 0

note that it needs to be an uppercase O, not a zero.

[broupe]

Thanks!
-O helped a lot I think…

now I have to fix the “path to…hvcc-freezer.lv2 folder” command;
methinks there’s something wrong with the syntax…

scp -rp -O Users/bjarneroupe/Downloads/hvcc-Freezer.lv2 root@192.168.51.1:/root/.lv2
root@192.168.51.1’s password:
Users/bjarneroupe/Downloads/hvcc-Freezer.lv2: No such file or directory

[DaveM]

/Users maybe instead of Users.

[broupe]

Thanks DaveM!
That concluded my quest.

finally Freezer is back on my pedalboard!

Thanks to all you great people:

You’re welcome
…and in my opinion, Freezer is a great plugin
