Web Server Bleg

35 Comments

Geek Alert for this post.

I’m running a web server app on my computer, which I can address by http://localhost:8080/webapp, where “webapp” is the app.

It works fine, but in theory, I should be able to access it from another machine on the network via http://localhostIP:8080/webapp, where “localhostIP” is the IP address of my machine, but I can’t. It just times out.

I’ve even installed Apache on the machine, and I’ve set up a reverse proxy in the Apache config file per the following:


ProxyRequests On


Order deny,allow
Deny from all
Allow from 192.168

#Set up reverse proxy for Webapp server

ProxyPass /webapp/ http://localhost:8080/webapp/
ProxyPassReverse /webapp/ http://localhost:8080/webapp/
ProxyPreserveHost On

Again, where “webapp” is the actual webserver that I’m trying to access remotely.

When I try to access this from either a remote, or my local machine, by http://localhostIP/webapp, I get the message: “The requested URL /webapp was not found on this server.”

Any Apache gurus who can tell me what the problem might be? I’ve opened up firewall to both http and https.

Problem solved. As noted in comments, it was a combination of allowed ports and SELinux.

Twit

I just noticed that I have almost thirty followers on Twitter, even though I have only tweeted once since joining a couple years ago. I was feeling a little guilty, so I’ve set up my RSS at the blog to feed it. I may or may not start actually manually tweeting in the future, but at least there’s some content there now.

Conference is over, and Patricia and I are driving down the coast highway. We’ll be stopping in Cambria tonight, and then back to LA tomorrow. I might keep an eye on things with my phone, but I won’t be posting much, if at all. Be good in comments.

I’m heading off to drive up to the space conference in Mountain View, and will arrive some time this evening. Be good in the comments sections.

[Late evening update]

Had a good drive up, except for getting stuck in a traffic jam for an hour just east of Gilroy. Got a good whiff of garlic, though.

Back on line tomorrow morning from the conference. Lori Garver is the headliner.

I’ve done some amount of searching, and I can’t figure out whether it’s possible to automatically feed the RSS from my blog to my stream, and if so, how to do it. I see lots of instructions as to how to follow streams in an RSS reader, but not the other direction. Anyone know? I currently do this on my FB wall (I never manually post anything on FB, other than comments to others’ posts), so if Google doesn’t offer the capability, they need to catch up.

Someone asked a similar question in the forum on Tuesday, with no replies yet.

A Suggestion for Mozilla

In the next version of Firefox, can you please put in a little utility that tells me which tab in which browser instance is causing it to eat up the CPU? Just this blog post took several minutes to create…

[Update Tuesday morning]

Folks, note that this is not a memory problem (I’ve got eight gigs of RAM) — it is a CPU problem. I have a quad-core Phenom II, and it still gets brought to its knees, at least in Firefox, but sometimes it slows down everything.

Firefox Problems

2 Comments

So, I recently upgraded to Firefox 4 in Fedora Core 14. It’s not officially supported (it’s supposed to be part of Core 15), but it seemed to install all right from an rpm. The other day, after an unrelated reboot, it started acting strangely. It wouldn’t reload my tabs from the previous session (the “Restore” button did nothing but go gray when I hit it). Also, it’s no longer loading Firefox 4 when I click on the icon for it — it loads 3.6. I actually removed 3.6, and 4, and reinstalled 4, using yum (after renaming my old .mozilla folder). I didn’t reinstall 3.6. Yet when I run Firefox, it runs 3.6. Other symptoms — the Firefox tab in the task manager at the bottom of the screen has no Firefox icon (it’s just generic), the search function doesn’t work.

Does anyone have any idea what’s going on?

[Update a while later]

Per a suggestion in comments, I did find a Firefox 5 package for Fedora 14. It seems to be working all right so far, except I’ve probably lost all the open tabs I had (and there were many dozen). Though perhaps all of the open tabs were part of my problem…

Fedora Sound Problem

5 Comments

For the first time evah, I finally got the Nvidia drivers installed on my machine (I had been using nouveau), and the video is great. Problem is, I’ve lost sound in videos. It’s not an intrinsic sound problem — I can still hear system sounds, and the audio in Second Life (which is the reason I finally broke down and fought with the system to get the video drivers installed) is fine. But when I play Youtube, silence. Anyone have any ideas?

[Update a while later]

It’s not just Youtube — videos in general don’t work (e.g., PJTV).

[Update a few minutes later]

OK, continuing to narrow it down. It’s a Firefox problem. Things are fine in Opera (which I assume means that it’s not an underlying Flash problem).

[Update a few minutes later]

Never mind. I shut down and restarted Firefox, and all seems to be well now…
