wget does not work most of the time

[centguy]

update: Things seem to work a little better now but I still do not understand certain points:


If I boot up CentOS 6 (with /etc/sysctl.conf containing two lines to disable ipv6) and use firefox everything is normal. Good!
Now I ping a computer in my company called 10.217.164.107, nothing happens (expected because I have not established the vpn connection yet).

Without quiting firefox, I run the vpn script ncsvc to connect to my company VPN, then
the window that is running
ping 10.217.164.107

shows just two lines of (something like)

64 bytes from 10.217.164.107: icmp_seq=2634 ttl=62 time=6.06 ms
64 bytes from 10.217.164.107: icmp_seq=2635 ttl=62 time=5.97 ms

and it hangs.

To establish a working connection, I have to close all internet application (in this case just the firefox).
relaunch vpn connection, and the window with
ping 10.217.164.107
shows the the data is continously transferred.
Now, I can ssh to my remote computer computer and use the firefox as per normal.

Question: Do I really have to stop all internet services before I launch vpn ?

That's how it works for me too.

Thanks giulix63 for confirming.

I now leave the ping window on. Once I see there is no transmission, I know that I need to restart my network manager, or
rerun vncsvc.

Overall the VPN connection is very unstable from time to time. I thought it was the CentOS 6.1 problem, but apparently CentOS 6.6 (much less tested since I
just installed it) also have the same problem.

Sometimes I need to run many times vncsvc and key in the passwds before I can
get a stable connection, and then I am not sure when I will be kiced out from the vpn connection. This is rather serious.

I am so upset about it (this happened after after switching to fibre optics network, which is supposed to be faster, but it bring tonnes of problems for me).

Still wget is still consistently broken..

I just wish someone understand my problem.
