Putty: Incoming Packet was garbled on decryption

Question

I am unable to connect to my server on my local network (VM).

I have multiple servers I am able to connect to.

When I try to putty into the server, I get the message

Incoming Packet was garbled on decryption

What I've tried:

I googled and tried to implement their solution -- force blowfish and ssh2. Still does not work.

How do I fix this?

Answer 1

I just had this problem. This is what I did to fix it:

Download latest version of PuTTY (I was using 0.62 instead of 0.63) In PuTTY configuration, go to Connection->SSH and move "Blowfish" to the top of the list under "Encryption cipher selection policy".

Answer 2

i had the same problem "Incoming Packet was garbled on decryption".

for the connection i used:

> putty.exe -proxycmd "plink.exe john@81.163.163.63 -P 22 -nc 10.10.10.10:22 -i c:\Users\john\.ssh\id.ppk " john@10.10.10.10  -i c:\Users\john\.ssh\john.ppk

the solution=> First of all launch "plink" part of the command:

> plink.exe john@81.163.163.63 -P 22 -nc 10.10.10.10:22 -i c:\Users\john\.ssh\id.ppk

it will ask "the server host key is not cached". Just click "yes", "yes" etc.

After that launch full command:

>putty.exe -proxycmd "plink.exe john@81.163.163.63 -P 22 -nc 10.10.10.10:22 -i c:\Users\john\.ssh\id.ppk " john@10.10.10.10  -i c:\Users\john\.ssh\john.ppk

in my case it solved the problem.
