network problem after reinstallation
Hi everybody,
For some reasons, I have reinstalled Arch GNU/Linux a few weeks ago:
[bastien@zoulou ~]$ last -num 5
wtmp begins Wed Sep 18 16:29:10 2013
[bastien@zoulou ~]$ I have changed my box config from STATIC to DHCP.
After this reinstallation, I have some network problems that I do not know how to handle...
1 - after the launch of Thunderbird, I get the error message "Failed to connect to server [.....]".
So I close it then restart it immediatly, then I get the error message "Looked up [....]", then, sometimes it works,
sometimes I have AGAIN to close Thunderbird then restart it. And it works.
2 - if I have launch Thunderbird for some time, I cannot send a message. I have to close/restart Thunderbird
then I can send a message (if I don't wait before clicking on Send !).
3 - I have same problem with PACMAN. I sometimes have to click CTRL+C then re-run again PACMAN.
Here are my config files:
[root@zoulou bastien]# cat /etc/netctl/dhcpd
Description='A basic dhcp ethernet connection'
Interface=net0
Connection=ethernet
IP=dhcp
## for DHCPv6
#IP6=dhcp
## for IPv6 autoconfiguration
#IP6=stateless
[root@zoulou bastien]# [root@zoulou bastien]# cat /etc/resolv.conf
# Generated by resolvconf
domain home
nameserver 192.168.1.1
[root@zoulou bastien]# Do u have an idea?
Thanks!

Re: network problem after reinstallation
I think your network is going up and down. I assume this is a wired network.
How are you controlling your network? What services are you starting from systemd? (post the output of systemctl --no-pager )
My guess is that you have multiple services vying for control of the network.

Yes it is a wired connection.

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
107 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
[bastien@zoulou ~]$ Also, as you can see I have added a udev rule:
[bastien@zoulou rules.d]$ cat /etc/udev/rules.d/10-network.rules
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="00:24:1d:c9:f9:3a", NAME="net0"
[bastien@zoulou rules.d]$ Thanks,

Re: network problem after reinstallation
Did you enable both netctl and dhcpcd services? if so, then disable the dhcpcd service.
If you are not sure, please post the output of ls /etc/systemd/* -l

I never get such error message with Firefox.

Re: network problem after reinstallation
Perhaps I misunderstood. Is Thunderbird the only program with which you are having problems?

Re: network problem after reinstallation
Hi,
pacman also.
with Firefox I had such problem. I had to press F5 several times, but then I checked the connection settings and found out that there was a "use Proxy" checked box.
So I only have problems with pacman and Thunderbird.
But strange, over the last two days I had no problem with pacman. But I have changed nothing...
Thanks,
Bastien
