IMP 12.5 EXTERNAL FILE SERVER - Public KEY Doesn´t FIT IN

[aheredia0519840]

Hello Everyone, 

I'm out of ideas with this, I've followed the Cisco guide for MFT, the problem is when I want to add the File Server's public key into the IMP server, but the External File Server Public Key field does not seems to take all the public key. 

I've searched and tried many things but nothing works, I hope you guys can help me.

Public Key on IMP: X.X.X.X ssh-rsa XXXB3NzaC1yc2EAAAADAQABAAABgQCye890Q2/Np/ttY9RaDckUo7O34L19J5+9hszjQq08xUEvGeDx/r4vI4PVh4BuSy/fYIk8H9g4zSvFAzQhi8mnGSuQIe+XNaYBOryxvTRAKZ30NODz2TcupNrPCujDrjxTMLvSU9g08XD0tZgCPMOogaR2pVw15EO3gE+jcWiBIBkZKTyKNEbimaC1JEBL2WKZYMzjFMnlOwiZ6UB7by1UjKMLh9x5p4zVG2Plf8qFCREfsmt8O8HitNkDFpclqpRuXZNuJnaBvNCCZUTPZ+FUmRWZZ5SajXHydqjihz+wHyZmM7jzwV38JRp0ApgdddVyb7foxJXeWrpNVlz206TQjtSysCFJw4kj1V20J+wpJLgNe8cyMFf640f8YnGLZYf4K3maxHPTBsliacFnRxhTe0WC0fzcM/KZz3pYVJZGty7q12/CjJosuuRGl6xvR

@Roger Kallberg may have more guidance....

How long is that key exactly? Is it longer than 4096?

Hello @Maren Mahone,

thank you for your answer, I really didn't know the key length, but solved this generating a knew key pair of 2048.

Hi,

I ma having a similar issue. How did you generate a new key using 2048?

I got it working after downgrading to version 16 from version 19

Hi Collinks2,

How did you do this? I have a similar issue on 10.5 IMP. I want to connect the external file system (CentOS 8.0).

Please advise,

B

@Balazs Balogh,

I installed Ubuntu server 16.0.I followed the mft guide.You will also need to install Microsoft sql server Database.

Centos 8 should also work.

so you will create user. Go to the user directory.Navigate to .ssh and create authorized_file

copy the public node key from imp and past in this authorized_file

refer to the below link for more information
