pidgin 2.6.6 Unable to connect to Yahoo on Fedora 13
 

I installed pidgin 2.6.6 on fedora 13 and setup as following:
protocol: yahoo
pager server : scsa.msg.yahoo.com
port: 5050
file transfer server: filetransfer.msg.yahoo.com
file transfer port: 80
proxy: Use GNOME Proxy Setting

But I received the error:
Unable to connect to Yahoo

I tried the previous post about connecting to 66.163.181.166 or changed port but still didn't work.

However I have another computer with linux FC4 and the pidgin 2.6.2 installed on FC 4 with same configuration works.

the full error in the fedora logs would help

besides the unsupported and very out of date fedora 4 what are the differences in hardware between 4 & 13 computers?

what SELinux settings and set in fedora 13 ?
is there a SELinux error also for this ?
is port 5050 open in fedora 13 ? ( iptables should have it closed by default)

I looked at debug window and found out on fc13 (it's a lenovo t400):
(11:36:49) proxy: Connecting to login.yahoo.com:443 with no proxy
(11:36:49) proxy: Connection in progress

(11:36:49) connection: Connection error on 0x8699798 (reason: 0 description: Unable to connect to login.yahoo.com: SSL Connection Failed)

however on fc4 (dell latitude d810):

I set up company proxy address:port at proxy/automatic proxy configuration on both laptops. But don't know why the old computer pick up the proxy configuration

What is SELinux settings and set in fedora 13? Is it SELinux boolean?

SE is a kernel mod for security
in the 4 install i am betting it is not installed or set to the default( at the time ) permissive fedora 13's default is ENFORCING

SELinux
http://sradvan.fedorapeople.org/SELinux_FAQ/
http://en.wikipedia.org/wiki/Security-Enhanced_Linux
the orig creators page
http://www.nsa.gov/research/selinux/index.shtml

yes on fc4 se is not installed:
cat /selinux/enforce
cat /selinux/enforce: No such file or directory

on fc13:
[root@localhost]# cat /selinux/enforce
1
[root@localhost qiqili]# echo 0 > /selinux/enforce
[root@localhost qiqili]# cat /selinux/enforce
0

but after I changed it to permissive mode, and reconnect, it was able to connect to
scsa.msg.yahoo.com:5050 through company's proxy, but not connected to login.yahoo.com:

at this point ?
one thing fedora did change the software for the network back in 7 ( i think )
it went from "network" to "network-manager "
see the fedora services for that . The old one might still be in there but turned off.
http://www.mjmwired.net/resources/mj...3.html#network
http://www.mjmwired.net/resources/mjm-services-f13.html

Network is online:

"Option 2: In Gnome, [Right-Click] on the Networking icon in the top left of the toolbar.
Select Edit Connections....
Select System eth0 and click Edit...
Check Connect automatically and click Apply.
Enter 'root' password when prompted. "

I checked the "option2" and "connect automatically" was checked.

Here is the copy from fc4 debug windows for connection on login.yahoo.com wich was failed on fc13:
