Ethernet

Recommended Posts

Thanks, have now set up shorewall. AND have managed to reliably connect/disconnect broadband via the network-icon. But perhaps I spoke too soon about it working first time, because that isn't always the case; quite frequently the system boots without starting eth1 and then no number of attempts to connect via the icon works. On checking in MCC/System-services I've noticed that netplugd is not set to 'on boot'; is this significant? Also, I did not provide any of the Hostname/DNS server/Gateway information when setting up the connection, essentially because I don't know it and, since the connection works anyway, I thought it was optional. Probably not.

When you installed shorewall did you use:

 

urpmi shorewall

 

If so, I've had problems before. If you go into MCC, Security, and then Firewall, go through the GUI configuration, and make sure you choose the ethernet card.

 

I found that when I didn't do this, after rebooting I couldn't access the internet, but as soon as I stopped the shorewall service, it would start working.

 

It then turned out to be a slight configuration problem.

Have just installed shorewall on this hdd as you suggested - via the gui. Just one point, though; MCC does not say whether or not shorewall has been successfully installed, although I assume that all is OK. Is there any way of checking this on-line other than selecting verbose at boot-time?

At the CLI, you can type:

 

service shorewall status

Can you post an "ifconfig -a"?

 

Also, if you ping your router, do you get any errors like destination unreachable? This will show if the firewall isn't configured properly as I found in my case, when I had to go to mcc and reconfigure.

Am still a novice; don't know how to 'ping'

Open a terminal, log in as root (type "su", and enter the root password), then type e.g.

 

ping www.siteyouwanttoping.com

or

ping 123.456.789.000

 

for more options, type

man ping (for quitting the manpages, type "q")

or ping --help

Tried with ping www.mandrivausers.org, which resulted in:

 

PING mandrivausers.org (83.245.15.165) 56(84) bytes of data.

64 bytes from kwh.kernow-gb.com (83.245.15.165): icmp_seq=1 ttl=53 time=27.1 ms

..

..

64 bytes from kwh.kernow-gb.com (83.245.15.165): icmp_seq=36 ttl=53 time=30.4 ms

 

When I terminated it with Ctrl-C the answer was:

 

--- mandrivausers.org ping statistics ---

36 packets transmitted, 36 received, 0% packet loss, time 35032ms

rtt min/avg/max/mdev = 26.523/28.013/31.762/1.157 ms

 

Presumeably this is positive :unsure:

It could be an ipv6 issue if you are having problems browsing etc. What's your web browser? If Firefox, try:

 

about:config (in the url address bar)
filter for ipv6
change from false to true

 

then, what might be worth doing if still having problems browsing, to add this line to /etc/modprobe.conf

 

alias net-pf-10 off

Currently both broadband modem and Firefox are working well - that's LE2005 with shorewall - so I'll keep these tips in mind for when the router is installed. Thanks.

With regard to my paranoia about hackers, if I'm not using the web I cut the connection via the network-icon, which needs root permission. Is there any way of avoiding this, i.e. giving permission to a specific user, perhaps in a similar way to enabling the pcmciahdd at boot via /etc/fstab?
