Probably useful for a lot of simple uses. Some CMS might ship Varnish as
part of it and there won't a need for CLI.

I really like this one. If we could have an option to let Varnish start
without the cache running (like -d) one could picture some sort of service
accepting connections from newly started varnishd servers. The service would
then configure the caches, provision them with VCL and start them up. The
need for messing around with having shell and config files on the
caches disappears.

Varnish CLI user feedback, please.

[Poul-Henning Kamp]

I'm looking at the CLI/varnishadm stuff right now, and would like some
feedback from you guys...

Right now (in -trunk) we have these possible CLI configurations:

A)  no CLI at all.

B)  CLI on stdin (-d)

C)  CLI on TELNET (-T)

D)  CLI on "call-back" (-M)

If the -S option is given, -T/-M CLI connections will require
challenge/response authentication.

(Before 2.1, I plan to add -S support to varnishadm, and maybe some
API functions to access the CLI in libvarnishapi.)

Which of these modes do you actually use ?

Are more modes needed ?

Any other insights on the CLI interface ?
