Hi all,
When I start DSL I can't access the internet. However, after I unplug and replug my USB ethernet adapter, I can connect.
First, some of my system specs: Dual boot Windows98/Linux (flavor of the day, right now it's DSL) Dell Latitude laptop 400 MHz PII 128 Mb RAM 6 Gb HD Billion 5200S ADSL modem/router (provided by ISP) Realtek RTL8150 USB ethernet adapter (I don't have an NIC card, that's why I use the adapter).
Here are the results of "ifconfig eth0" and "route" for the before and after unplug/replug scenarios:
BEFORE: # ifconfig eth0 (just the first 3 lines) Link encap: Ethernet HWaddr 00:E0:4C:03:38:08 inet addr:192.168.1.33 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
#route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 58.8.37.1 * 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
AFTER: # ifconfig eth0 Link encap: Ethernet HWaddr 00:E0:4C:03:38:08 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
#route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 58.8.37.1 * 255.255.255.255 UH 0 0 0 ppp0 default ppp-58.8.37.1.r 0.0.0.0 UG 0 0 0 ppp0
So, while I'm very happy that I can connect to the internet with only the trivial step of unplug/replug, I am curious as to what's going on. Further, the issue isn't so trivial in other distros. In Slax, for example, when I unplug my USB cable the computer freezes ("kernel panic"). In Gentoo-based systems, nothing seems to happen (i.e. I still can't connect after replug). In Puppy, the whole unplug/replug is a non-issue since it works right out of the box.
Can anybody here help to explain this to me?
Thanks, Gerry
