How to setup multiple SSH keys

Irakli Ghachava

Hi, I've followed the guidelines for setting up multiple SSH keys in bitbucket but it doesn't work.

Here is my setup

~/.ssh/config

Host github.com
IdentityFile ~/.ssh/github
IdentitiesOnly yes

Host bitbucket.org-{username_1}
HostName bitbucket.org
User git
IdentityFile ~/.ssh/bitbucket-nari

Host bitbucket.org-{username_2}
HostName bitbucket.org
User git
IdentityFile ~/.ssh/bitbucket-delori

I can't connect to either bitbucket.org-{username_1} or bitbucket.org-{username_2}.

ika@Iraklis-MacBook-Pro ~ % ssh -Tv bitbucket.org-{username_2}
OpenSSH_9.8p1, LibreSSL 3.3.6
debug1: Reading configuration data /Users/ika/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 21: include /etc/ssh/ssh_config.d/* matched no files
debug1: /etc/ssh/ssh_config line 54: Applying options for *
debug1: Authenticator provider $SSH_SK_PROVIDER did not resolve; disabling
debug1: Connecting to bitbucket.org-{username_2} port 22.
ssh: Could not resolve hostname bitbucket.org-{username_2}: nodename nor servname provided, or not known.

 

Here is local git config in one of my repositories

 

[user]
name = {username_2}
email = {email}

[core]
  repositoryformatversion = 0
  filemode = true
  bare = false
  logallrefupdates = true
  ignorecase = true
  precomposeunicode = true

[remote "origin"]
  url = git@bitbucket.org-{username_2}:trsthb/dpp-portal.git
  fetch = +refs/heads/*:refs/remotes/origin/*

[branch "master"]
  remote = origin
  merge = refs/heads/master
  vscode-merge-base = origin/master

[branch "develop"]
  remote = origin
  merge = refs/heads/develop
  vscode-merge-base = origin/develop

Everytime I run git pull it throws following error

 

ssh: Could not resolve hostname bitbucket.org-irakli____ghachava: nodename nor servname provided, or not known 

fatal: Could not read from remote repository. 

Please make sure you have the correct access rights and the repository exists.

What am I doing wrong here?

 

P.S. Yes, I've added public keys to corresponding bitbucket accounts in personal bitbucket settings.

Hello @Irakli Ghachava ,

thank you for reaching out to the Community!

This happens because the alias you used in your SSH configuration file is not being correctly translated to a valid hostname when you're trying to connect. The alias you define should match exactly what you use in your Git remote URL.

Double-check your SSH config and Git remote URL for any typos. The alias in the SSH config (bitbucket.org-{username_1} and bitbucket.org-{username_1}) should match exactly with what you use in your Git remote URL.

Also, confirm if the owners of the ssh config file is the same user executing the command.

You can check if the configuration is correctly taking place by testing the SSH with more verbose logs : 

ssh -Tvvv git@bitbucket.org-{username1}

If the config file is properly configured, we will expect a log similar to below at the very beginning:

debug1: Reading configuration data /Users/<username>/.ssh/config

debug1: /Users/<username>/.ssh/config line 7: Applying options for bitbucket.org-{username_1}
