Hi Harry,

Tks for your advice.

Knoppix LiveCD 4.0.2
1.5 Mb ADSL broadband via modem

If I understand you correctly you are talking about one computer booting any of 3 different OS, and not 3 different computers.
No, on the same PC. WinXP and FC3 are running on separate HD.

I have my problem partitially solved with following step;
One of the nameserver assigned died.

# cat /etc/resolv.conf
Code:
nameserver 202.123.77.196 
nameserver 202.123.77.213
# ping -c 3 202.123.77.196
Code:
PING 202.123.77.196 (202.123.77.196): 56 data bytes

--- 202.123.77.196 ping statistics ---
3 packets transmitted, 0 packets received, 100% packet loss
# ping -c 3 202.123.77.213
Code:
PING 202.123.77.213 (202.123.77.213): 56 data bytes
64 bytes from 202.123.77.213: icmp_seq=0 ttl=252 time=17.8 ms
64 bytes from 202.123.77.213: icmp_seq=1 ttl=252 time=18.2 ms
64 bytes from 202.123.77.213: icmp_seq=2 ttl=252 time=18.2 ms

--- 202.123.77.213 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 17.8/18.0/18.2 ms
After reverting their order, web browsing was much faster than before.


However each time booting up Knoppix LiveCD 4.0.2, /etc/resolv.conf is an empty file with no entry.

# cat /etc/resolv.conf
Code:
# Insert nameserver here 
# nameserver 127.0.0.1
After setting up ADSL broadband connection, following nameservers are assigned automatically;
nameserver 202.123.77.196
nameserver 202.123.77.213

But "nameserver 202.123.77.196" is not active. Each time I have to revert their order.

How to get it corrected? ISP only provides dynamic IP. DNS server is in ISP's office.

Regarding disable ipv6 in the kernel, I have to run
echo "alias net-pf-10 off" >> /etc/modprobe.conf
echo "alias ipv6 off" >> /etc/modprobe.conf

and reboot Knoppix LiveCD afterwards to take effect. But once reboot all entries disappear. Is there any suggestion? Tks.

Other informations are as follows;

CPU AMD Athlon 1.4
RAM 512MB
ADSL Modem NEC, Model ATU R-110, MAC Add 00-01-38-02 -09 -3C

How have you configured Knoppix without a router?
As follows;
Connect PC to ADSL modem and run;

Kstart --> Systems --> ADSL/PPPOE configuration
then following its instruction.

Try pinging sites by URL and by IP address and see if there is an extreme difference in how long it akes for you to get a response whn using URLs (not how long the ping is, but if it actually takes much longer with a stopwatch to get a response).[/list]

Is there a way checking the speed of ADSL broadband? I'm interested to know the actual speed of my 1.5Mb ADSL broadband connection. TIA
