CLI
slugs
Check whether an HTTP slug is available before reserving it.
HTTP tunnels are addressed by a globally-unique slug (<slug>.intunnel.eu). Before you
reserve one with up http <slug>, check it's free.
tunnelctl slugs check <name>check validates three things — format, the reserved-name list, and whether someone
already owns it — and exits 0 if the slug is available, 1 if not.
$ tunnelctl slugs check myapp
myapp is available
$ tunnelctl slugs check myapp
myapp not available (already reserved by user test@example.com)# gate an `up` on availability
tunnelctl slugs check myapp && tunnelctl up http myapp 8080Slug rules
Slugs are DNS-safe: 3–32 characters, lowercase letters, digits and hyphens, starting and ending with a letter or digit. See Tunnels & protocols.
(The TCP/UDP equivalent — checking a port — is ports check.)
