Steve Kemp writes about security issues with C programs [1]. It seems obvious that if you are going to do something that is overly tricky (such as anything related to setuid programs) then you should have a good knowledge of what you are doing. Steve goes a little further and suggests that anyone who doesn’t [...]

I had an old Compaq Athlon 1GHz system that seemed to be broken. It would display random things on the screen from the BIOS and fail the boot, it looked like a motherboard problem. Fortunately before I gave it away (I give away all my broken machines to members of my local LUG who want [...] Using the “ulimit” controls over process resource use it is possible to limit RAM for processes and to limit the number of processes per UID. The problem is that this often is only good for accidental problems not dealing with malicious acts. For a multi-user machine each user needs to be allowed to have two [...] When previously writing about how I partition disks [1] I mentioned that I use smaller RAID partitions than the maximum size to reduce reconstruction time in the event of a crash. Linux software RAID has a feature known as write intent bitmaps which means that every time some data is about to be written the [...] I’ve just been working with a Flash device used as /dev/hda (the root filesystem) for a router. The aim is much the same as with my idea of using an EeePC as a router [1]. The client in question may consider the EeePC for future deployments but are concerned about the ability of ASUS to [...] Having had a number of hard drives fail over the years I use RAID whenever possible to reduce the probability of data loss caused by hardware failure. It’s unfortunate that some machines make it impractically difficult to install a second hard drive (my laptop and some small form factor desktop machines I have given to [...] It seems to me that the Asus EeePC (a $AU499 ultra-light laptop with only flash storage) would make a decent router. Often full desktop PCs are used as routers because they run the most common software and have standard interfaces. There have been dedicated router devices with flash for a long time, but without the [...] It is not uncommon to run a Linux system with a kernel that was compiled for another distribution. One reason for doing this is the difficulty in compiling and testing a kernel to make sure it will do what you require. It’s not THAT difficult for someone who knows what they are doing, but if [...] At the end of the month we are having linux.conf.au (one of the best Linux conferences in the world) in Melbourne. Here is some quick advice for people who are attending: If you have not yet booked a hotel then www.wotif.com is a good option to try, it’s a hotel booking web site that is [...] Are there any active LUGs in Singapore? A friend in Singapore is about to set up his laptop to dual-boot and would like the possibility of getting some direct help if it ends up not booting Windows… I looked at the Linux.org page listing LUGs in Singapore [1]. There are two entries, one has a [...] |
