Here is my yum.conf:

PHP Code:



[main] 
cachedir=/var/cache/yum 
keepcache=1 
debuglevel=2 
logfile=/var/log/yum.log 
pkgpolicy=newest 
distroverpkg=redhat-release 
tolerant=1 
exactarch=1 
obsoletes=1 
gpgcheck=1 
plugins=1 
metadata_expire=1800 
proxy="http://192.168.3.1:8080" 
#export http_proxy 
# PUT YOUR REPOS HERE OR IN separate files named file.repo 
# in /etc/yum.repos.d

when I perform yum update O get this:

I have tried in my yum.conf and nothing works but I can browse the internet!

PHP Code:



http_proxy="http://192.168.3.1:8080" 
export http_proxy

I have run out of options. help!

My immediate thought regarding your 'proxy' statement in yum.conf, is have you tried without the "" surrounding the proxy url? I wouldn't think this would help, though I have never used them and I don't recall seeing in doco this way. Shouldn't be too hard to test. Also, try a `yum clean all` command to flush all the cached yum data.

Next thought, is do you have access to the proxy server logs? If so, have you checked them to confirm that your yum is in fact trying to use the proxy. Also, check any other obvious errors from the proxy server side.

Further troubleshooting you could do, is either iptables logs (assuming you are using iptables) to see where the traffic is going and/or tcpdump to see what the http headers are reporting.

Also I know for a fact the yum.conf, proxy, entry does work, but don't know if it takes precedance over the http_proxy environment variable. If you have it set, try clearing it, do make sure only the yum.conf setting is being used.

Finally, have you added a "logfile" parameter to your yum.conf? This is not on by default, but will allow you to have yum write to a log file. This may give you some more clues as to the source of the problem. Check out `man yum.conf` for further details on logging.

I set a port on my switch for SPAN and I have collected data that I will analyize tonight. I will also look at the firewall logs and well as the squids logs as well. I have other machines on the same subnet that do have any problems at all downloading and uploading things going through the proxy. So it wouldnt supprise me if I dont see anything abnormal. It has to be something on that server.

Did you try any of the easy stuff I mentioned?
I went an did a quick test on my Fedora8 PC which isn't going to be too much different from a yum standpoint, and found that if I have "" around my proxy line in yum.conf, I do get an error when I try to run yum. SO ... did you remove the quotes and test?

Here is a text log from my quick test:
[root@fedora ~]# cat /etc/yum.conf |grep proxy
proxy="http://192.168.1.200:3128"
[root@fedora ~]# yum list
Options Error: Error parsing '"http://192.168.1.200:3128"': URL must be http, ftp or https not ""

You have to also add a trailing slash or you might get:

Code:

just add this line to you yum.conf
proxy=http://come.com:80/

[root@localhost ~]# yum update
