das geht mit rinetd oder mit iptables. Beispiele solltest Du im Netz finden, oder sprich mit nochmal an, dann helfe ich Dir gerne.

Sebastian, ist deine etwas eigenwillige art zu quoten absicht? micha

Schau dir mal den rinetd an...

vielen Dank an alle Antwortenden für diesen Tipp! Unter SuSE 8.1 habe ich zwar rinetd installiert, doch es fehlt die /etc/rinetd.conf als Beispieldatei zum Editieren. Könnte mir hier einer eine solche Beispielsdatei posten? Danke! -- Herzliche Grüße, Stefan Hofmeir

Hi! I've a problem with the kernel bootloader. But i can't find the error.... i'm trying to change the kernel bootloader, so that i can boot from an diskonchip device directly with the kernel. the device which is used is /dev/nftla ( dec: 93:00). my idea was to copy ( with dd ) the kernel to the device /dev/nftla and then i partition the disk with one primary partition beginning after the kernel ( cyl 90 or 100 for example ) theoretically the kernels bootloader (512 byte ) should end before the partition table and only some variables are stored at 497 .. so there could be a broken partition table.. but this should work --> but it fails. normally there should be printed msg1 at the beginning, but nothing happens. anyway thx for helping mfg Robin Stemmer __________________________ stemmer@sevenbits.org Appendix: here are some hardware infos: ------------------------------------------------------------------------------------------- embedded 386sx, 4mb ram diskonchip m-systems 2200 (kernel with diskonchip support (mtd).. not patched) kernel 2.4.20 (lolo-sources because of size) 574995 bytes chip is found at 0xE0000 and some other devices ..
