can't connect true ssh with other machines

Post by GioMBG » 2018/04/30 09:07:30

Hi All,
after a lot of try I come here asking for suggestions in how to understand way I can't connect from my CentOS to some machines using keys...
Specifically I gave my key.pub to the maintainers of the servers with which I have to connect and they assure that have just install the key but every time I try to connect : for example :

Code: Select all

sftp -oPort=2222 user@11.222.333.444
their server ask for passwd like any key is installed...
any suggestion ?
always thanks

Several possibilities but most of them require you to have access to the logs on the destination server to diagnose. Permission problems, if there are any, on the key files on the destination server will be logged by sshd when you try to connect. Get them to check that as a first step.

Second, CentOS 7's ssh has dropped support for several old and insecure encryption methods. Running your client in verbose mode might help to find out if this is the problem.
CentOS 5 died in March 2017 - migrate NOW!

If your user is not set for sftp only you can use 'ssh -v' for easier debugging.
