Title:
netstat statistics overflow
Status in net-tools package in Ubuntu:
Fix Released
Status in net-tools package in Debian:
Fix Released
Bug description:
Binary package hint: net-tools
In netstat's summary "netstat -s" the fields 'InOctets' and
'OutOctets' appear to be a 32 bit signed value. When sending or
receiving large amounts of packets the values occasionally wrap around
and change sign.
$ netstat -s
...
IpExt:
...
InOctets: 201874790
OutOctets: -2029455654
...
The raw data however is correct:
$ cat /proc/net/dev

Versions:
ubuntu 10.04 - x64_86
net-tools 1.60
netstat 1.42 (2001-04-15)
Netstat should use a bigger integer type, at the very least use an
unsigned interger type.
