Can anyone tell me where to find info on Virtual Memory size limitations. By Virtual Memory I'm talking about the VIrtual Memory that is used when mapping physical pci controller memory to Virtual Memory space. What and where are the limitations of how much a system can use and so forth. I am running out of it and need to find out why and how I can (if possible) increase the amount available. I'm using 2.4.16-SuSE kernel. Sorry if this it WAY OFF TOPIC but I am using SuSE and I know there are lots of very knowledgeable people on this list. Thanks in advance Mark
IIRC, the base kernel is limited to 1GB of physical memory with 3GB of
virtual memory per process and 1GB for the kernel. The 4GB flavor
(e.g. 2.4.16-4GB kernel) can handle 4GB of physical memory. It is not
clear to me that it can handle anymore virtual memory.
Taken from the help in "make menuconfig" on 64GB memory model:
This selection turns Intel PAE (Physical Address Extension) mode on.
PAE implements 3-level paging on IA32 processors. PAE is fully
supported by Linux, PAE mode is implemented on all recent Intel
processors (Pentium Pro and better). NOTE: If you say "64GB" here,
then the kernel will not boot on CPUs that don't support PAE!

I'm trying to forward port 6969 on my firewall to port 22 of an internal machine. I've tried the following: $IPTABLES -t nat -A PREROUTING -p tcp -d <external ip> --dport 6969 -j DNAT --to 192.168.1.1:22 I have also tried: $IPTABLES -t nat -A PREROUTING -p tcp -d <external ip> --dport 6969 -j DNAT --to-destination 192.168.1.1:22 and finally I tried: $IPTABLES -t nat -A PREROUTING -p tcp -d <external ip> --dport 6969 -j DNAT --to-dest 192.168.1.1:22 I have had no luck with any. Anybody have suggestions? Adam

Are you using SuSEFirewall2? There are options in the configuration file for FW_Forward and FW_Redirect , numbers 13 - 15. Maybe that is what you are looking for? -- $|=1;while(1){print pack("h*",'75861647f302d4560275f6272797f3');sleep(1); for(1..16){for(8,32,8,7){print chr($_);}select(undef,undef,undef,.05);}}

Actually I'm using a firewall script put together from a basic tutorial. I do not have SuSEFirewall2 on the machine and would prefer to not have to install it since I already have a script. I'm looking for the actual IPTables command to do this forwarding. Adam
