Newbee's problem related to ssh configuration

@aha_1980 alt text

I already did it and It shows like this. Is the state right?

Hi @ylink,

yes that looks good. And you use the user name that is in the Profile section as the SSH <username>?

Can you run ssh -vvv -p 29418 <username>@codereview.qt-project.org and see where it complain?

Regards

It complains as follow:

The problem is I run command "ssh-keygen -t rsa -b 4096 -C youremail@email.com -f ~/.ssh/yourgerritusername_id_rsa" as wiki described before and I only got 2 files, a private key and a public key. I don't know why the connection complains lack of other files?

@ylink

could be QTQAINFRA-1530, please see there for workarounds.

@aha_1980 Here's another error message after fixing the private key problem......The message is "packet_write_wait: Connection to 54.229,21,112 port 29418: Broken pipe"

@ylink

Is it correct that the SSH version changed between the two logs?!

I currently have no idea for the broken pipe error - please google around a bit.

Can you ssh to other servers?

In the worst case, you can use Gerrit with HTTP also, the HTTP password is in your personal settings in Gerrit.

@aha_1980 The second log is from my ubuntu OS while the first is from windows bash. Still thanks for your help.

My steps:

cd /home/user8937666/QtProj/key/
ssh-keygen -t ed25519 -f /home/user8937666/QtProj/key/my_qt_ssh_key -N "" -C myKeyForQt <<< $'\ny' >/dev/null 2>&1
ssh -vvv -p 29418 user8937666@codereview.qt-project.org  -i /home/a/QtProj/key/my_qt_ssh_key

Now works (thanks). But with default RSA (without -t ed25519 ) it doesn't work (error "no mutual signature algorithm"), why?
