hello. i have following setup: a machine (winChip 200mhz cpu, 32mb ram, linux 2.4.28) acting like a bridge with 2 interfaces (eth0 - to our ISP, eth1 - to our network) machine does not have any IP there is a 802.1q vlan eth0.2 eth0.2 and eth1 are bridged in br0 i have one 4mbit link which i share with my friend, i have 3mbit and he has 1mbit al...

- Renamed IMAGE_BASE to LD_IMAGE_BASE_OPT. - Moved "-fcommon" to KLIBCREQFLAGS in scripts/Kbuild.klibc. - Remove "dash" warning fixes which have been upstreamed. - Conditionalize the inclusion of compiler flags by using the proper compiler name or "cc-option". - Added "-Werror" to "cc-option" to catch flags that cause warnings. - Retain

I've updated CentOS 4.0 to 4.1 on several machines (some desktops, some servers). However on my laptop, update is failing with following error just after headers are downloaded: --> Running transaction check --> Processing Dependency: glibc-common = 2.3.4-2 for package: glibc --> Finished Dependency Resolution Error: Missing Dependency: glibc-common = 2.3.4-2 is needed by package

A friend has an old Pentium-133 laptop with 32MB of memory and a 1.3 GB hard disk that he wants to use as a web server for a very small community. Will CentOS (or any other RHEL derived distribution for that matter) install and run with acceptable performance on such a system, or will a specialized distribution like Damn Small Linux be a better choice? In this case, disk space is not a big

mb() typically uses mfence on modern x86, but a micro-benchmark shows that it's 2 to 3 times slower than lock; addl $0,(%%e/rsp) that we use on older CPUs. So let's use the locked variant everywhere - helps keep the code simple as well. While I was at it, I found some inconsistencies in comments in arch/x86/include/asm/barrier.h I hope I'm not splitting this up too much - the reason

Hi there good people, I''m a newbie in what concerns running Linux on machines other than desktops, so I need help from all you gurus out there :-) I have Linux installed on an old computer (Winchip C6, Pentium clone), acting as a router/firewall for two other computers. Both these machines are connected to the firewall via a dedicated ethernet card each, on different subnets, 192.168.0.7 (eth1) and 192.168.10.3 (eth2). Internet connection (eth0) is a 3Mbit/320Kbit cable modem. The firewall bo...
