RE: [Snort-users] Fedora Core Linux 3 -- Snort IDS

Try updating yum (I know, sounds a little strange) do "up2date yum" and
then run "yum update"

Subject: [Snort-users] Fedora Core Linux 3 -- Snort IDS

Hello Friends,

I have installed FC3 on my m/c and I want to configure
Snort, snort snarf, IDS Policy Manager & snort inline
(IPS) . But for that I wanted to have the latest Linux
o the box.
Buy when I try to do yum -y update (or) yum update I
get errors.

My configuration are:

/etc/yum.conf
-------------

[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
retries=20
obsoletes=1
gpgcheck=1


# PUT YOUR REPOS HERE OR IN separate files named
file.repo
# in /etc/yum.repos.d

/etc/yum.repos.d/local-base
---------------------------

# My local FC mirrors
http://mirror.stanford.edu/fedora/linux/core/3/$ARCH/os/
http://www.mirrorservice.org/sites/d...pub/fedora/lin
ux/core/3/$ARCH/os
http://www.las.ic.unicamp.br/pub/fedora/linux/core/3/$ARCH/os/

/etc/yum.repos.d/local-updates
------------------------------

# My local FC update mirrors
http://mirror.stanford.edu/fedora/linux/core/updates/3/$ARCH/
http://www.mirrorservice.org/sites/d...pub/fedora/lin
ux/core/updates/3/$ARCH
http://www.las.ic.unicamp.br/pub/fedora/linux/core/updates/3/$ARCH



/etc/yum.repos.d/fedora.repo
----------------------------

[base]
name=Fedora Core $releasever - $basearch - Base
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/$releasever
/$basearch/os/
#mirrorlist=http://fedora.redhat.com/download/mirrors/fedora-core-$releaseve
r
mirrorlist=file:///etc/yum.repos.d/local-base
enabled=1
gpgcheck=1


/etc/yum.repos.d/fedora-updates.repo
------------------------------------

[updates-released]
name=Fedora Core $releasever - $basearch - Released
Updates
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/updates/$re
leasever/$basearch/
#mirrorlist=http://fedora.redhat.com/download/mirrors/updates-released-fc$re
leasever
mirrorlist=file:///etc/yum.repos.d/local-updates
enabled=1
gpgcheck=1


Now I tried the following & got the error report that
follows:
--------------------------------------------------------------

[root@secure yum.repos.d]# yum update
Setting up Update Process
Setting up Repo: base
http://mirror.stanford.edu/fedora/li...ta/repomd.xml:
[Errno 4] IOError: <urlopen error (-3, 'Temporary

http://www.las.ic.unicamp.br/pub/fed...epodata/repomd
..xml:

http://www.mirrorservice.org/sites/d...pub/fedora/lin
ux/core/3/i386/os/repodata/repomd.xml:

Trying other mirror.

more mirrors to try.
[root@secure yum.repos.d]#
[root@secure yum.repos.d]# pwd
/etc/yum.repos.d

Now I tried the -y option:
--------------------------

[root@secure yum.repos.d]# yum -y update
Setting up Update Process
Setting up Repo: base
http://www.mirrorservice.org/sites/d...pub/fedora/lin
ux/core/3/i386/os/repodata/repomd.xml:

http://www.las.ic.unicamp.br/pub/fed...epodata/repomd
..xml:

http://mirror.stanford.edu/fedora/li...ta/repomd.xml:

Cannot open/read repomd.xml file for repository: base
failure: repodata/repomd.xml from base: [Errno 256] No
more mirrors to try.
[root@secure yum.repos.d]#


Conclusion:
-----------
I tried all the options , but without any avail, I am
able to browse & connect to Internet from my Linux box
& able to ping the Gateway,
but as per above the Error 256 has something to do
with Name resolution.

Can anybody please help me in this scenario.


Thanks & Regards

Pradeep
