Could not create directory /var/teamsserver

Question

I've installed os x server (Mavericks) on my mac and would like to add bot. For some reasons my remote repo is located on other external server and I have access to it by username and password on specified port. I've added remote repo to os x server like this:

ssh://1.2.3.4:PORT/path/to/repo.git

...filled username and password.

Then I've added bot in Xcode but when I hit integrate it fails with logs:

Cloning into 'ssh_myusername_1_2_3_4_PORT_path_to_repo_git'...

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

SSH Known Hosts file path is located at /Library/Server/Xcode/Config/ssh_known_hosts

SSH strict host checking is enabled (you can disable this by editing the

SSHStrictHostKeyChecking key in /Library/Server/Xcode/Config/xcsbuildd.plist

Untrusted HTTPS certificates is disabled (you can enable this by editing the

TrustSelfSignedSSLCertificates key in /Library/Server/Xcode/Config/xcsbuildd.plist

I assume that there is a problem with permissions but in my /var there are some directories with different permissions and of course there is no teams server folder...

So I don't know how to setup proper permissions (without changing permissions of other subdirectories of /var...). I can try manually make directory "teams server" but don't know with what permissions... ? Do you have any ideas?

EDIT: For test purpose I've created teamsserver directory with 777 but that doesn't solve my problem. Logs looks the same as previous butjust WITHOUT line:

Could not create directory '/var/teamsserver/.ssh'.

Any ideas?

Thanks

Answer 1

I experienced a similar issue with scheme action build scripts when attempting to run git commands against a github repo protected by ssh key pairs.

Bots run builds using a _teamsserver system account. As you've discovered, these accounts don't have home directories by default. To setup builds to access and modify their home directory, I had success with the following (your mileage may vary):

sudo mkdir /var/teamsserver
sudo chown -R _teamsserver:_teamsserver /var/teamsserver/
sudo chmod -R 770 /var/teamsserver/

HTH

I did 3 things to allow me to get past this, although I'm not sure which of them solved the problem:

1. Change all git repositories in my project to use the HTTPS rather than SSH (git) version of the url
2. Disabled SSHStrictHostKeyChecking as per the instructions from the source control log from the bot.
3. Enabled TrustSelfSignedSSLCertificates as per the same instructions from the log.

Also check out https://discussions.apple.com/thread/5586872 in case this is a problem for you.

I will back some of these items off and test when I have more time.

Answer 3

If you've tried the above and still are getting a permission denied error, you probably don't have the right permissions to that file/directory.

• Who are you running as? $id
• $ls -al the directory that the server is trying to read the id_rsa from (Probably similar to this path: Library/Server/Xcode/Data/BotRuns/BotRun-a28db5fc-1932-47a0-a528-f52c75e421e2.b‌​undle/credentials/65885363-194e-454b-a3ce-56dcaaf5d3c9/id_rsa)
• change ownership of that file ^^ ($sudo chown {#id} {#path})

Answer 4

Ok, I took some time but I've a solution... Two solutions actually. Ashamed to admit but read and understand logs is enough to solve the problem (again :P).

FIRST ANSWER:

My server host key was added to .ssh/known_hosts BEFORE installing os x server. Server does't use that path of known hosts. As log says server uses:

SSH Known Hosts file path is located at /Library/Server/Xcode/Config/ssh_known_hosts

and that file was empty in my case. So to solve the problem it is enough to copy known_hosts to ssh_known_hosts:

sudo cp ~/.ssh/known_hosts /Library/Server/Xcode/Config/ssh_known_hosts

It's that simple.

SECOND ANSWER:

Acording to log again

SSH strict host checking is enabled (you can disable this by editing the SSHStrictHostKeyChecking key in /Library/Server/Xcode/Config/xcsbuildd.plist

Change SSHStrictHostKeyChecking to false.

It's done again.
