Some weeks ago I bought an AMD64 X2 which now I must connect to the internet, using my old Pentium 4 as router to the dynamic address I receive from my cable provider whenever I boot. Having used Testing since it came up in Potato times, I never needed and never acquired networking knowledge. Debian did all that for me,
After three weeks of studying books, manuals and HOWTOS and try- ing to configure the two computers, I am constantly running in circles. I can ping from one computer to the other and from the old computer to the internet, and I can do everything I did be- fore with my old computer, but there is no connection at all between the new one and the internet. This I need urgently be- cause the AMD 64 has only a daily build netinst Etch I downloa- ded and burned to disk on October 17th. It is terribly castra- ted (even using 'more' instead of 'less'), but there is no way out of the networking circles without apt-get or aptitude which seem to be unreachable. My third computer, the one within the skull, seems to be rapidly loosing flexibility and efficiency after an uptime of more than 75 years. I have tried to sum up the important data using the names in the following paragraph. Real names are different, of course. All this is a bit lengthy, but since I avoid opening attach- ments wherever I can i think it is better to leave it in the body of the posting.. ==================================================================== OLD - old computer, Intel Pentium 4 2.40 GHz, Debian Testing, Kernel 2.6.17-2-686 (Debian 2.6. 17-9); INTERFACES eth0 and eth1 NEW - new computer, AMD Athlon 64 X2 Dual Core 4200+.
