How to set up PuTTY for direct access to your Tool Labs account
You are likely going to set up connections to each of the login servers:
The remaining configuration options are identical for all login servers. Of course, you may prefer screen and scroll buffer sizes of your choice:
How to set up WinSCP for direct access to your Tool Labs account
After connecting to your Tool Labs account with WinSCP, you may then wish to connect to a particular TOOL account directory (e.g. foobot, or my-tool, etc). Following are instructions (using WinSCP v5.5.0).
- Access the root directory by clicking the root directory icon. (A folder icon with a backwards slash in the right/remote pane of WinSCP) You will now be in /<root>.
- Scroll down to the the data directory and double click to access.
- Next double-click on the project directory. (accessing some of these directories may take several seconds, so be patient)
- Scroll down to the tool of your choice and double-click. You are now in your chosen TOOL directory.
To get back to your Tool Labs account directory click the root directory icon again, then home, then scroll down to your username directory and double-click.
Troubleshooting permissions errorsSometimes the file system permissions on the tool's directory (
/data/project/$TOOL) can get messed up and be missing the group write permission. You can check the current permissions by logging into a bastion and showing the directory:
$ ssh tools-login.wmflabs.org $ ls -ld /data/project/bd808-test drwxrwsr-x 7 tools.bd808-test tools.bd808-test 4096 Jul 19 15:07 /data/project/bd808-test/
- "d" - this is a directory.
- "rwx" - These are the permissions for the directory's owning user. "r" - read, "w" - write, "x" - eXecute.
- "rws" - These are the permissions for the directory's owning group. "r" - read, "w" - write, "s" - sticky. Sticky implies execute and also attempts to set the same group ownership on all new files and directories created inside the directory.
- "r-x" - These are the permissions for "other" users (users who are not the owner or in the owning group). The "-" means that other users cannot write to this directory.
$ ssh tools-login.wmflabs.org $ become $MY_TOOL $ chmod -R g+w /data/project/$MY_TOOL # Recusively grant write permission to the group on all files and directories.
