Tcpdump , ethereal , not worthy ? Multithreaded aplication ?
If you wanna measure/count how many bytes does a client receive ( on the server side ) , you can easily implement a contor , for receive bytes.Suposing that all byte's receive by one client are send by the server , it's easy to make something like :
Code:
send(j,da,sizeof(da), 0);
Let's say da is the string passed to the client ( a client J ).You incremenent a contor so measure how many bytes are transfered to the client.
Let's say I send 4 bytes to the client ( once ) and then 3 .. I can do this.
Code:
int j;
int TRAFIC=0; /* start 0 bytes transfered to client j */
nbytes=send(da,sizeof(da),0);
TRAFIC=TRAFIC+nbytes;
So if all trafic to a specified client , is send by the server to that client , you can easily count how many bytes , are received by the client J .
I'd like to find out how to redirect Outbound packets.
So instead of having packets go to IP1 as they normally would, have them go to IP2 instead.
I believe this is possible using IPFW but I'm not sure. I've played with it, but haven't gotten too far.
Any ideas would be appreciated. (1 Reply)
I am working on a project, which has the following type of hardware setup.

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.
Now, I'd like to capture RAW... (1 Reply)

Hello
I need to send some packets to check connection. Packets will be catch by snoop. Is there any Sun tool to send some packets on selected IP and Port?

hi guys
I've configured snmp on some linux
snmpd.conf
rocommunity com_read x.x.x.10

But I have no idea how to configure that basically when SNMP is configure there... (5 Replies)
I was checking routing table, and noticed that our server has a lot packets from localhost:

Hi,
I'm quite new to unix networking and ip tables. I'm running a debian (htpc) server with two NIC's; eth0 and wlan0.
I'm trying to set it up in a way that eth0 is the default interface for internet, but some processes should run through wlan0.
For example, I'm using eth0 for downloads... (2 Replies)

ssl_ctx_get_client_ca_list
SSL_get_client_CA_list(3) OpenSSL SSL_get_client_CA_list(3)NAME
SSL_get_client_CA_list, SSL_CTX_get_client_CA_list - get list of client CAs
SYNOPSIS
#include <openssl/ssl.h>
STACK_OF(X509_NAME) *SSL_get_client_CA_list(const SSL *s);
STACK_OF(X509_NAME) *SSL_CTX_get_client_CA_list(const SSL_CTX *ctx);
DESCRIPTION
SSL_CTX_get_client_CA_list() returns the list of client CAs explicitly set for ctx using SSL_CTX_set_client_CA_list(3).
SSL_get_client_CA_list() returns the list of client CAs explicitly set for ssl using SSL_set_client_CA_list() or ssl's SSL_CTX object with
SSL_CTX_set_client_CA_list(3), when in server mode. In client mode, SSL_get_client_CA_list returns the list of client CAs sent from the
server, if any.
RETURN VALUES
SSL_CTX_set_client_CA_list() and SSL_set_client_CA_list() do not return diagnostic information.
SSL_CTX_add_client_CA() and SSL_add_client_CA() have the following return values:
STACK_OF(X509_NAMES)
List of CA names explicitly set (for ctx or in server mode) or send by the server (client mode).
NULL
No client CA list was explicitly set (for ctx or in server mode) or the server did not send a list of CAs (client mode).
