in a xen environment , i see a lot op dropped packets via netstat -i
Is this a sign of network problems, or is it normal to see this kind of numbers? i'm not sure how to interprete the data. is this normal, bad, critical. What are your stats on this?
I guess i have a xen issue of some sort, but not sure what yet
I'd like to make a script that I can execute every time I sign on to my linux box that keeps track of the time and allows to me to add a remark to a file. So basically once I log in, I run the script, and it outputs the date and time to a text file (log.txt). But that isn't my problem.

Hi,
My Solaris Workstation has got 4 NICS, out of which one of them(bge3) is unplugged from the rest of the external network & connected to other interface(bge1). The isolated NIC serves as a simulated Ethernet Interface for my application under development.

pcap_stats
PCAP_STATS(3) Library Functions Manual PCAP_STATS(3)NAME
pcap_stats - get capture statistics
SYNOPSIS
#include <pcap/pcap.h>
int pcap_stats(pcap_t *p, struct pcap_stat *ps);
DESCRIPTION
pcap_stats() fills in the struct pcap_stat pointed to by its second argument. The values represent packet statistics from the start of the
run to the time of the call.
pcap_stats() is supported only on live captures, not on ``savefiles''; no statistics are stored in ``savefiles'', so no statistics are
available when reading from a ``savefile''.
A struct pcap_stat has the following members:
ps_recv
number of packets received;
ps_drop
number of packets dropped because there was no room in the operating system's buffer when they arrived, because packets
weren't being read fast enough;
ps_ifdrop
number of packets dropped by the network interface or its driver.
The statistics do not behave the same way on all platforms. ps_recv might count packets whether they passed any filter set with pcap_set-
filter(3) or not, or it might count only packets that pass the filter. It also might, or might not, count packets dropped because there
was no room in the operating system's buffer when they arrived. ps_drop is not available on all platforms; it is zero on platforms where
it's not available. If packet filtering is done in libpcap, rather than in the operating system, it would count packets that don't pass
the filter. Both ps_recv and ps_drop might, or might not, count packets not yet read from the operating system and thus not yet seen by
the application. ps_ifdrop might, or might not, be implemented; if it's zero, that might mean that no packets were dropped by the inter-
face, or it might mean that the statistic is unavailable, so it should not be treated as an indication that the interface did not drop any
packets.
RETURN VALUE
pcap_stats() returns 0 on success and returns -1 if there is an error or if p doesn't support packet statistics. If -1 is returned,
pcap_geterr() or pcap_perror() may be called with p as an argument to fetch or display the error text.
