Just installed Centos 4.0 from CDs. I am behind a proxy server which requires authentication. I can successfully browse the web with Firefox after configuring for the proxy in Firefox and responding to the authentication prompts. I can successfully run wget through the proxy (even downloading the xml file that yum failes on - see below). So far my only failure is with yum.

Reading the yum documentation and other forum and google comments, I see references to proxy setting in yum.conf and to the environment variable http_proxy. I've tried both with no success.

With the proxy defined in yum.conf and no http_proxy set, I get the following:

[root@dbatux etc]# yum update
Setting up Update Process

http://mirror.centos.org/centos/4/addons/i386/repodata/repomd.xml: [Errno 4] IOError: <urlopen error (111, 'Connection refused')>
Trying other mirror.
Cannot open/read repomd.xml file for repository: addons
failure: repodata/repomd.xml from addons: [Errno 256] No more mirrors to try.

With http_proxy set, I get the following:

My http_proxy is set to this format "http://username:password@proxyip:port"

Thanks for help in advance.

man yum says:



So in /etc/yum.conf try this:

Thanks, but as I said in my original post, I tried setting these three variables in yum.conf with the result below. I also tried increasing the errorllevel and debuglevel parameters, but yum produced no additional errors or logs.

[root@dbatux etc]# yum -d 10 update

I too had no success using the proxy options in yum.conf, instead I set the HTTP_PROXY variable in /etc/profile to make it work.

/etc/profile

......
HTTP_PROXY="http://yourproxy.yourdomain.com:80"
export HTTP_PROXY
.......

don't forget to source it to make it available

What do you mean by "don't forget to source it to make it available"?


Thanks

Hello

I'm use proxy allso, by hand with export ...
Today I find question and answer by hughesjr.

Like bingo. I try, but without succes to reach mirror. So I look in man and there find solution which hughesjr talk about.

So in /etc/yum.conf I change
proxy="http://proxyip:port"
proxy_username="username"
proxy_password="password"

to
proxy=http://proxy.mydomain.si:80/
proxy_username=
proxy_password=

I set proxy without username and password and write 3 lines without quotation.
And yum update start to work without exporting http...

Does the proxy apply to ftp also? many times the yum+proxy issue can be fixed by simply using a mirror with ftp access instead of http access.

yes, now I can also get ftp.

Hi --

I'm still having this issue myself. Putting HTTP_PROXY into my /etc/profile helped, now I get a 407 instead. Are there other variables I can set to get the username and password in there? Having them in my yum.conf didn't help at all.

Thanks.

EDIT: the fix is -- http_proxy=http://user:passwd@proxy.foo.com:portnumber

Hi

Good Day

I have read through this thread and I still dont see an answer?? I have tried to update the http_proxy in info in the yum.conf file as well as in the /user/.profile file.

I cant seem to do a yum update,or install software as It downloads it does the following

[root@nagios ~]# yum search nagios
Searching Packages:
Setting up Repos
update 100% |=========================| 951 B 00:00
http://mirror.centos.org/centos/4/os/i386/repodata/repomd.xml: [Errno 4] IOError: HTTP Error 400: Bad Request
Trying other mirror.
Cannot open/read repomd.xml file for repository: base
failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try.
[root@nagios ~]#


Now should the yum.conf file be updated or should the .profile be updated?
I used the following
http_proxy="http://username:passwd@150.1.1.49:80"

Cheers

Try the python fix at the following link and it should remedy the situation:
