I've been having problems with Ubuntu since I upgraded to 9.04. My primary concern is the time in which it takes to authenticate a login and sudo command.
When logging into Gnome, it takes about 2 minutes to login. The logon screen appears to freeze, but after a period of time the desktop loads.
Then there is sudo. Running a sudo command can take well over a minute, about the same time as the desktop login.
Finally, there is the console login (Ctrl+Alt+F1). The is the result every time:
MYHOST: user1
passsword:
Login timed out after 60 seconds.
Ubuntu 9.04 MYHOST tty1
I timed an ssh login from a remote host and it took nearly 2 minutes before it timed out on authentication of my password. Doing an ssh from the local host (MYHOST) failed as well. Yes, ssh is running and is accessible.
I'm not sure if it's an issue at the networking/resolution level, so here is some of that info:
This is my /etc/hosts file:
127.0.0.1 localhost
127.0.1.1 MYHOST
This is my routing table:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
link-local * 255.255.0.0 U 1000 0 0 eth0
default 192.168.1.11 0.0.0.0 UG 100 0 0 eth0
I'm not sure why the virtual bridge (virbr0) is configured. I removed all bridge definitions from /etc/network/interfaces:
MYHOST:/$ more /etc/network/interfaces
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
#auto br0
#iface br0 inet dhcp
# bridge_ports eth0
# bridge_fd 9
# bridge_hello 2
# bridge_maxage 12
# bridge_stp off
Lastly, here is some dmesg output:

[ 25.152504] eth0: no IPv6 routers present

I wonder if the bridge has anything to do with it. Everything was working fine in 8.10.
Any help would be appreciated.
