curl: (7) couldn't connect to host // wget --> failed: Connection refused.

linea · 05-27-2009, 10:35 AM

Hi all,

I am quite a newbie. I have Mandriva 2009 Spring installed on a Thinkpad T40. All works well but since last week I have broken somehow curl and wget :

Quote:

[tompot@localhost]$ wget http://www.yahoo.com
--2009-05-28 08:08:58-- http://www.yahoo.com/
Connecting to 217.19.195.242:80... failed: Connection refused.

Quote:

[tompot@localhost]$ curl http://www.yahoo.com
curl: (7) couldn't connect to host

One clue I have is, since I installed XAMPP, I have created the xampp service and might have modified something else for curl and wget.

Please, don't hesitate to refer me to another solved thread to reseach.

Thank you

Hi

welcome to LQ!

Is the URL still accessible via ordinary browser? What's the
network topology, are you behind a proxy/firewall? What do
you see when you

Code:

telnet www.yahoo.com 80

?

Cheers,
Tink

Thanks Tinkster,

I forgot to mention

I have still perfect access to the internet (all url) via http and ftp with FF 3.0.10.

lynx doesn't seem to be working :

Quote:

[tompot@localhost]$ lynx http://www.yahoo.com

Looking up 217.19.195.242
Making HTTP connection to 217.19.195.242
Alert!: Unable to connect to remote host.

lynx: Can't access startfile http://www.yahoo.com/

Telnet isn't installed on my config.

but dig seems to work :

Network is local wifi with 3 machines + printer. Sisco router.

Where should I start looking ?

I tried Konqueror. Same probleme as Lynx not access to any url.

Either somehting special with my firefox config for http and the filezilla for ftp.
Or Firefox is messing up the mandriva build-in browsers.

Tinkster · 05-27-2009, 02:02 PM

I don't think ff has that power ... if you don't have telnet - how about netcat?
Is SE Linux enabled, and your FF the only browser permitted out on ports 80
and/or 443?

You could also try to run curl or wget under strace, log info ot a file and
see where you get errors/permission problems ...

Cheers,
Tink

No telnet, no netcat either
SELinux is RH distro isn't it ? I am Mandriva.--> no idea about ports opened for which browser.

I am looking at the strace output... won't be easy

For info while I try to understand the raw output, here is the -c output :

My search didn't bring me anywhere

Can someone help me ?

Tinkster · 06-01-2009, 11:45 AM

Not with that amount of info. I'd highly recommend installing
either telnet or nc (nc being the predfered choice because it's
far more versatile).

Cheers,
Tink

jamescondron · 06-01-2009, 11:50 AM

Whats in /etc/hosts? Firefox used to do funny things resolving via hosts, especially if you have some proxy set up. Is that all clear?

Thank you.

Give me :

127.0.0.1 localhost

I managed to install netcat. Here is what it gives :

Quote:

[root@localhost etc]# netcat -v www.yahoo.com 80
www.yahoo.com [209.131.36.158] 80 (http) open
read(net): Connection reset by peer

Tinkster · 06-02-2009, 01:32 AM

Hummm ... still doesn't make any sense. Is there a proxy
somewhere that firefox knows about, and other browsers
don't?

linea · 06-02-2009, 01:38 PM

Excellent Tink, you got me on the way.
I feel like a moron now.

I changed proxy settings on drake gui...
Now wget and curl is working.

However netcat is still giving me the same thing.

In my mother tongue I'd say "Touche pas à ca p'tit con".

Thanks a lot Tink.

Mcdo · 05-21-2012, 12:56 PM

curl and wget try to download things through proxy even if the proxy is unavailable. so the simplest way is to export http_proxy="" and put it into your .bash_profile.
