CentOS 5.4 repositories

The pptp repository doesn't seem to work with 5.4.  yum list times out:

 
 http://poptop.sourceforge.net/yum/stable/rhel5/i386/repodata /primary.sqlite.bz2: [Errno 4]
Socket Error: (104, 'Connection reset by peer')
 Trying other mirror.
Same problem for other mirrors.

 rpming from it times out:
 rpm -ivh http://pptpclient.sourceforge.net/yum/stable/rhel5/pptp-release- current.noarch.rpm
 Retrieving http://pptpclient.sourceforge.net/yum/stable/rhel5/pptp-release- current.noarch.rpm
 error: /var/tmp/rpm-xfer.MLsFA7: headerRead failed: hdr blob(7575): BAD, read  returned 3568
 error: /var/tmp/rpm-xfer.MLsFA7 cannot be installed

wget gets a percentage, times out, gets some more, times out, etc.
Visiting with browser loads some and then times out

from non-5.4 machines things seem to go smoothly, of course I don't install
from there because it is the wrong version.

I talked to the people at Sourceforge for a while.  They did some tests and
then said everything there was OK, so it might be something with the pptp
part  (e.g., pptpclient). I did try various IP connections and MTU sizes
set., none of which worked.

Any known problems with the pptp site and CentOS 5.4?  Could it be a 5.4
error? Stuff from other repositories seems to yum install OK.  Here is my repo:

[pptp-stable]
name=PPTP Client stable repository for Red Hat Enterprise Linux $releasever ($basearch)

I suspect that this is due to ICMP filtering somewhere between your system 
and the sourceforge website:

pppd fails when init connection with kernel 2-6-28.10


Hi all, 

I was using linux kernel 2.6.22 with pppd 2.4.4 in an embedded hardware
(powerpc architecture) with a GPRS serial module. I was able to make a GPRS
connection, but now I've upgraded kernel version to 2-6-28.10 and pppd to
2.4.5 and it doesn't work. These are the log messages after sending the
ATD*99***1# command, when pppd is started:

Re: CentOS 5.4 repositories

Yes but I don't believe we block 3 and 4 ICMP packets or the problem would
manifest itself elsewhere too.  Maybe the 5.4 is doing it somehow?
I do not believe our router is.
