set kernel parameter use_fastroute


I have many problems with my Alpha server. There is an older operating system (4.0D). The system crashs often because of bad arp messages. They said, I have to patch the kernel with "use_fastroute=0". But I don't know how I must do it? Can somebody help me?

best regards

Re: set kernel parameter use_fastroute

kdbx -k /vmunix /dev/mem
(kdbx) patch use_fastroute=0
(kdbx) exit

that's it....

Re: set kernel parameter use_fastroute


I believe the kdbx>patch command changes the ondisk vmunix, to change the equivalent in memory location, the a[sign] command can be used as follows:

kdbx -k /vmunix
(kdbx) a use_fastroute=0

or as follows:

echo "a use_fastroute=0" | kdbx -k /vmunix
