Can someone help me fix this issue. I am connected few hours before but then when I tried to rename a folder using Putty I got disconnected and got this error.
Error: Disconnected: No supported authentication methods available (server sent: publickey)
I've tried the following solutions I got from the net.
- Re-gen private key
- Convert .pem to .ppk
- Move .ppk to other folder that all user has permission
- Use the ff username user,root,bitnami,ec2-user
- I tried it in Cyberduck, Winscp, filezilla, Putty
Thank you I hope someone can help me.
bitnami developer here.
Depending on which platform you are working you could download again the .pem file in order to connect to your server.
If you are working on any of our launchpads (https://aws.bitnami.com/, https://google.bitnami.com/, etc.) you have the option
to download you .pem key, so it's not necessary to regenerate the key.
On the other hand, if you are working on the amazon ec2 console and you did not download the private key pair of your server in the moment of the creation of the machine you won't be able to connect to it again unless you create another machine.
In order to reconnect to the server you should download again the key files and use it with putty/filezilla/etc. Make sure you put the correct ip of the server or you won't have access to it.

I have Oracle Linux 8.5 in Oracle Cloud, and have been using the host for several months.
But today I was trying to setup vscode remote ssh and looks like I messed up the ssh key that I use to login to the host. Now I cannot!
I tried to follow this documentation and this thread to fix some commands.
However, that did not help! And in fact now the host having difficulty stopping quickly; rebooting looks fine.
Any ideas on how to correct this issue?! (Was having a lot of fun until this struck :) )
In the OCI console, go to the instance, and click on the "console connection", this will show you 2 options, one is create local connection, which will allow you to upload a new ssh key file. Or you can create a console connection and then update the authorized_keys file with your new id_rsa.pub contents
Console connection did NOT work for me. That's why I went by attaching the volume to another instance. The documentation I followed suggests to mount /dev/sdb3. However that did not work for me. Instead, I mounted /dev/ocivolume/root, and modified the ssh key there, and now works!
I have AWS EC2 instance. I am using filezilla 3.8.0 but I cannot connect instance, filezilla doesnt accept account type normal and asking password. When I type user name ubunbu and password blank I received following message:
Disconnected: No supported authentication methods available (server sent: publickey)
I inserted pem key and converted ppk key also. My staff can connect but I cant. What is wrong?
Thanks
It happens in AWS EC2. As EC2 provide Connection through an SFTP need some other methods.
Firstly the CONNECTION will be in FTP as default. Need to change to SFTP.
Then instead of directly giving host name and password, it must be done in Site manager. Step by step procedure given below:
So the steps for troubleshooting:
Go to Filezilla's Settings
SFTP
Add Key File (Give the ppk converted key file or FZ will convert the pem ket)
Then take File in Filezilla
Go to
File
Site Manager
New Site
Give any name (ec2-amazon)
In General, give host name 'Public DNS' (eg: ec2-34-423.ap-southeast...)
Change the Protocol to SFTP
Logon Type: Normal
User : ec2-user or ubuntu - depends
Clear Password
Connect!
Hope you will be connected. Happy Hosting...:)
More specifically here's a screenshot of the dialog where you are supposed to add your ssh private key.
Try the following configuration in filezilla,
set Logon type = Interactive,Protocal = SFTP, and attach keyfile to filezilla SFTP setting from MenuBar -> Edit -> Settings ->SFTP -> Add Key File.
Hope this helps.
I was facing the same problem-
I follow up #Amith Ajith answer but found my setting was as it, is.
I choose a file as privatekey.pem which i generated.
Change "Transfer setting" as active
it worked for me.
I am using Windows 2012 R2 VM machine in Azure. I have read multiple article to setup Filezilla server in this environment. However, I am not successful. Any one faced this issue? Any solution will be greatly appreciated.
Just remember to add Filezilla to Windows Firewall :-)
I'm dealing with the same thing right now. locally the FTP serv works great. remote I cannot establish a passive connection. Based on my research this is because Azure is not set up for Passive-FTP. I am uncertain if we can get FileZilla to operate in a active-FTP mode. Will post back if I ever get to the bottom of it. Mine currently connects and authenticates but 'cannot retrieve directory listing' when it tries to kick over to passive (transfer) mode.
In addition to checking the Virtual Machine endpoints are open, be sure to also add the appropriate Windows Firewall rules if you have Windows Firewall enabled on your Windows VM.
Yes, We can connect to Azure server via FileZilla Client.
Steps:
Login to Azure portal: https://portal.azure.com
Click on App Services.
Select the Site and then click on Get publish profile.
Save the file and open it in notepad.exe.
The file contains 2 <publishProfile> sections. One is for Web Deploy and another for FTP.
Under the <publishProfile> section for FTP make a note of the following values:
publishUrl (hostname only)
userName --------------------------> This is the information you are looking for
userPWD
Add the PublishUrl to Hostname, Username and password in their respective fields.
Connected.

I'm trying to get a CI setup going and have got Mavericks server downloaded and linked with Xcode all on one machine.
Here's the set up:
Two git repos, hosted on OS X server, named CI and CISubmodule.
CISubmodule added as a submodule to CI
Every time I add bot I get a Host key verification failed error on integration. It's clear from the logs that the server is unable to clone CISubmodule due to an authentication error (I've tried SSH, HTTP, HTTPS) but I don't know why it's failing authentication.
I've set up the server so that logged in users can read and write.
I've tried everything mentioned here.
I'm guessing it's because the server is running as teamsserver and the repo is probably under my username, but I can't figure out how to give it permission to clone. Could it be that the SSH key requires a password? If so, how do I set it up so that it doesn't need a password any more?
Any guidance would be greatly appreciated.
Thanks,
Simon
I had the same case and I am not sure what happend exactly, I think the reason was I had more remote repository accesses and ssh keys pointing git-server side pointing to the same repository.
Deleting the remote repository accesses and cleaning up authorized_keys file helped.
I can confirm the CI server works with submodules, but make sure the .gitmodules file and xccheckout file point to the same repos
you may need to use passphrase-LESS keys for os x server to properly connect to 3rd party hosted git repos. it cannot connect with there is a passphrase needed.
ssh-keygen -p
it worked for us
One thing that helped me was to change my submodule URLs to use HTTPS instead of SSH.
When doing this, make sure that Xcode is actually using the new URLs. Even though I made the changes and pushed them, Xcode was caching the SSH URLs and using them. Remove all your SSH URLS from your server, then also remove them from your client under Preferences->Accounts. Then restart the server and restart Xcode, confirming that the new HTTPS URLs are being used when you create your bot.
I am trying to connect to EC2 server using putty with the help of .pem. It is giving me an error:
Disconnected: No supported authentication methods available (server sent: public key)
I have created a .ppk through puttygen. Still facing the same problem.
Can any one help me with the solution.
This usually means that there was a problem with how the pem file was converted to a ppk file, or that the pem file was not the right one to begin with. Make sure you followed the instructions for using puttygen correctly. There is an example here: Convert PEM to PPK file format
Alternatively, use a windows ssh client that uses pem files directly. Two options are:
Cygwin - it includes an ssh command line client.

U need a private key to connect to the server, the key U have probably is a public key, so U need to generate a private key in puttygen.
Perhaps, you use Ubuntu AMI. Should be user name - ubuntu.

For those searching, I had this issue but the latest authentication method was not supported by the old version of Putty. Upgrading Putty allowed me to connect.
I downloaded the latest Putty from the official website of Putty; then it required to uninstall, so I backed up by finding the key in the registry for:
HKEY_CURRENT_USER > Software > SimonTatham
By clicking on that entry and choosing File > Export and saved to desktop, this contains all the data and settings for Putty should something go wrong during uninstall.
Now with Putty backed up, you can uninstall Putty (CCleaner is a good option), and when it asks if you want to remove the sessions click NO, otherwise it will wipe the data, but fortunately you have the data backed up to the registry by this point.
Finally, now you can install the latest version of Putty. The latest version of Putty has the necessary authentication methods that AWS uses.
