Title: "ProxyPass URL must be absolute!" website meltdown
Post by: LANMonkey on December 23, 2012, 08:57:37 PM: I can no longer reach any of the websites, including webmail and server-manager. The terminal display shows a constantly repeated message,

Code: [Select]
Syntax error on line 1087 of /etc/httpd/conf/httpd.conf: ProxyPass URL must be absolute!
I can't log in at the terminal, but I can log on with PuTTY.

The only thing I can think of is that one of my ProxyPass targets is the Windows Home Server, which has the URL, symbiota.homeserver.com.

What should I do? I'm sure I've seen this problem before here, but a search has not pulled up any threads.

I'm sorry, but I do not understand the procedure, "rollback changes" nor have I applied any syntax anywhere in SME.

Post by: Stefano on December 23, 2012, 09:36:01 PM: then you are using ProxyPass

read here: http://wiki.contribs.org/SME_Server:Documentation:ProxyPass

you did something wrong.. you'd find the domain where you are using proxypass and revert/delete the settings
you should also take a look in bash history, it can help you (and us) to understand what's going wrong

OK, I'll uninstall ProxyPass, reinstall it and that should do the trick? I'll post the details of what I am trying to do with ProxyPass.

If you explain how to look up "bash history", I'll do that and post the results. Maybe I should to this first. Let me know what to do.

Apparently, this was one of the last things I was up to. But it was done a month ago at least.

You did not follow the instructions correctly. Read what you entered, and compare it with what the wiki says to enter
Do this to fix it (including the http: part & the trailing slash):

db domains setprop symbiota.homeserver.com ProxyPassTarget http://192.168.0.247/
(the above all on one line)
then do
signal-event domain-create symbiota.homeserver.com

Please read all instructions ACCURATELY & CAREFULLY in future!

Post by: LANMonkey on December 23, 2012, 11:07:23 PM: That did it!

The loop stopped in my terminal. Can I assume that a reboot is not necessary? All the websites are back up, including my WHS site.

As far as I can tell, Problem Solved.

Thank you very much.
