Hello all,
I am trying to work on the NFS and RPC, i am trying to understand
the code, i have enabled the debugging messages of rpc using rpcdebug -m
<module> -s all.
now i can see that lot of debug can be found in /var/log/messages, i do see
that there are lot of other debug messages printed in the nfs using dprint
other than there logs, so where can i find those logs, or is there any other
way to enable them.

Not sure if I understand you correctly, you meant you wanna filter which debug messages that belong to RPC and which ones aren't? If so, IMO perhaps grep could do some help? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com ^ permalink raw reply [flat|nested] 6+ messages in thread

They can often be modified later, but do it the easy way for now, just pass it in as argument to the kernel. If you're using grub, in your menu.lst file you should have an entry like: === title Desktop -- openSUSE 11.3 - 2.6.36.2-3 root (hd0,4) kernel /boot/vmlinuz-2.6.36.2-3-desktop root=/dev/disk/by-label/root resume=/dev/disk/by-id/ata-ST3250310AS_9RY00PYW-part1 splash=silent showopts vga=0x31a initrd /boot/initrd-2.6.36.2-3-desktop === Just add cpufreq.debug=7 at the end of the kernel boot line.
