labweb1001 and labweb1002 host Wikitech, Horizon and toolsadmin (Striker).
As wiki hosts they are fairly non-standard: code is deployed the usual way, but X-Wikimedia-Debug does not work, login uses the developer account (LDAP) credentials, and various things might be less reliable (e.g. logging).
Connecting
Connect to labweb1001 over ssh by proxying through a bastion (e.g. bast1003.wikimedia.org). As with other hosts, ensure you have ProxyJump configured in .ssh/config (see Production shell access). Then connect as follows:
user@laptop:~$ ssh labweb1001.wikimedia.org
Note that the domain name is .wikimedia.org, not .eqiad.wmnet.
Maintenance
labweb1001 and labweb1002 are load-balanced and redundant, using LVS. To take one of them out of service for maintenance, log in and run
labweb1001:~$ sudo depool
After maintenance, put the host back into service:
labweb1001:~$ sudo pool
Logs
Horizon logs are at /var/log/apache2/horizon_*, which can be scanned for failed user logins, etc. Make sure you check both labweb1001 and labweb1002.
