Newbee's problem related to ssh configuration

[ylink]

I am new here and want to start to contribute to the Qt project. I followed the step described in https://wiki.qt.io/Setting_up_Gerrit and got stuck in the 7th step of "Local Setup". I tried the command "ssh codereview.qt-project.org-gerrit gerrit stream-events" in both Windows PowerShell and Bash in Windows 10. however I received the error message: "ssh: Could not resolve hostname codereview.qt-project.org-gerrit: Name or service not known". How do I fix this? If I didn't provide enough information, please state in the comment and I'll add up.

Hi @ylink,

It seems there is a bug in the wiki, it should be

ssh codereview.qt-project.org gerrit stream-events

That said, I don't know what stream-events does. For testing, I always use

ssh -p 29418 <username>@codereview.qt-project.org. I have to specify username and port because I did not setup the sshconfig file.

Edit: Fixed the URL in the wiki

@aha_1980 said in Newbee's problem related to ssh configuration:

ssh -p 29418 <username>@codereview.qt-project.org

Thanks for your answer. I have tried your approach and there is no error message related to resolving hostname. Unfortunately, program returned a new error message: Permission denied (publickey). How can I fix this problem?

[aha_1980]

Hi @ylink,

have you uploaded you SSH public key to Gerrit? (Step 4 and 5)

[ylink]

@aha_1980

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

[aha_1980]

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 please post the ssh -vvv output again...

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?
