yum does not displayt URL of packages?

edencraze · 11-24-2009, 04:17 PM

One strange thing that struck me while using yum is that it does not display the URL of a package while its downloading it. All that I get to see is this:

Code:

(1/110): PackageKit-0.5.4-0.1.20091029git.fc12_0.5.4-0.4.20091029git.fc12.x86_64.drpm                 | 174 kB     00:01     
(2/110): PackageKit-device-rebind-0.5.4-0.1.20091029git.fc12_0.5.4-0.4.20091029git.fc12.x86_64.drpm   |  28 kB     00:00     
(3/110): PackageKit-glib-0.5.4-0.1.20091029git.fc12_0.5.4-0.4.20091029git.fc12.x86_64.drpm            |  26 kB     00:00

and a progress meter while the download is taking place.

I wonder if there is any option or plugin, which when turned on, will display the URL, from which each of these packages are downloaded, on the output.

yum wont tell you which URL, but it will tell you from which repo, and that is easily matched to URL in /etc/yum.repos.d/ or /etc/yum.conf

@centosboy: and how I do make out the complete URL using the information in the repo file? For example, what if, I want the URL from which the package "PackageKit" is being/has been downloaded... How do I find this out?

Kind of a tricky one to answer.
Say for example i want the repo URL where iptables is/was downloaded from...i could do this

Code:

yum info iptables

.....
Available Packages
iptables.i386                                                           1.3.5-5.3.el5_4.1                                                            updates

this tells me the updates repo contains this package.
so i check in /etc/yum.repos.d and find updates

Code:

#released updates
[updates]
name=CentOS-$releasever - Updates
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
exclude=kernel*
#protect=1

and the url is there. quite messy...

but this wont work if the package you are looking for is not available on any of your repos.

another command which does almost the same thing is the yum list package command. again, one of your installed repos must have the package or you will get no results

What i understood from trails is that yum downloads a metalink XML file using the url specified in the mirrorlist tag and then this XML file (metalink) contains a list of mirrors.

Code:

<?xml version="1.0" encoding="utf-8"?>
<metalink version="3.0" xmlns="http://www.metalinker.org/" type="dynamic" pubdate="Fri, 04 Dec 2009 21:16:17 GMT" generator="mirrormanager" xmlns:mm0="http://fedorahosted.org/mirrormanager">

    <file name="repomd.xml">
      <mm0:timestamp>1259815133</mm0:timestamp>

        <url protocol="ftp" type="ftp" location="IN" preference="100">ftp://mirror.cse.iitk.ac.in/fedora/updates/12/x86_64/repodata/repomd.xml</url>

        <url protocol="http" type="http" location="RU" preference="98">http://mirror.svk.su/fedora/linux/updates/12/x86_64/repodata/repomd.xml</url>
        <url protocol="ftp" type="ftp" location="RU" preference="98">ftp://mirror.svk.su/fedora/linux/updates/12/x86_64/repodata/repomd.xml</url>
        <url protocol="rsync" type="rsync" location="RU" preference="98">rsync://mirror.svk.su/fedora/linux/updates/12/x86_64/repodata/repomd.xml</url>
........
........
      </resources>
    </file>
  </files>
</metalink>

What complicates things is that the mirrors' URL point towards retrieving a repomd.xml file. When I looked into this file, I found that it contains a listing (in XML) pointing to locations from where i can download information about the files available from the server.

However, all this was done manually and to automate this sequence, I need to know how to expand the $releasever and $basearch variables in the .repo files. Do you know how I could automatically find this?
------------------------------
The reason I am going through all this headache is that certain files do not get downloaded directly. So what i do is create a tunnel using ssh to another server using the command ssh -D 1234 server.com and download the individual packages through this tunnel.

Do you happen to know of any method to make yum download automatically through this tunnel without me having to interrupt for each non-downloadable file?
