On my system also the files have 0 length (appart kcore (image of the kernel), maybe because it s just a virtual filesystem?
So, for instance you can access your cpuinfo by doing cat /proc/cpuinfo.
On one of our boxes I got:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 7
model name : Pentium III (Katmai)
stepping : 3
cpu MHz : 451.028941
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes

bogomips : 450.56

bogomips : 448.92
Also, a cat /proc/sys/net/ipv4/tcp_max _syn_backl og
returns 128
and if you should be able to increase it by doing:
echo 256 > /proc/sys/net/ipv4/tcp_max _syn_backl og
Beware that when you want to get data, less may not work where cat will.
(also avoid a cat /proc/kcore... or at least, use strings instead)

Thanks
