The multi-point host in the Network may have multiple IP addresses at the same time, especially when Dynamic Host address allocation is used, it is difficult to know what the IP address on the host is. The following uses a C program to list all IP addresses on the host. The code below is as follows:
Void print_all_ip (void)
{
Char szHostName [128];
(Is_array ($toList)) {
$this->to = Join ($toList, ",");
} else {
$this->to = $toList;
}
Set the Cc:recipient (s)
if (Is_array ($ccList) sizeof ($ccList)) {
$this-GT;CC = Join ($ccList, ",");
} elseif ($ccList) {
$this->cc = $ccList;
}
Set the Bcc:recipient (s)
if (Is_array ($bccList) sizeof ($bccList)) {
$this-GT;BCC = Join ($bccList, ",");
} elseif ($bccList) {
$this->bcc = $bccList;
}
}
Send the message; This is actually just a wrapper for

Article Title: how to configure multiple IP addresses for a network card in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
We know that in Linux, NICs are called eth0, eth1, eth2 ......, All Nic configuration files are stored in/etc/sysconfig/network-script/, the
Physical Environment: dual-Host amp; 43; multiple NICs amp; 43; one Nic is bound with two IP addresses amp; 43; switch scenarios with arp cache: the dual-host master-slave switchover uses a virtual IP address to provide unified external services. problem: After the master-slave switchover, the virtual IP address is bound successfully, but cannot be pinged to the same virtual IP address or the physical en

REDHATLINUX-DHCP (assign multiple IP segments)-Linux Enterprise Application-Linux server application information, which is described below. We all know that DHCP is required for dynamic IP allocation in the LAN. However, all DHCP information is transmitted in the form of broadcast, so it is impossible to pass through the router. This determines that a DHCP server can only assign IP addresses to clients in t

The MSYQL profile my.cnf has option bind-address=127.0.0.1, which means that MySQL server listens for local requests, and if any host can be open to request, write 0.0.0.0, but this is not safe. Listen to an IP, specify this IP address can be, but to ensure that MySQL user in the Allow this IP access, otherwise can not operate on the database. So is it possible to specify only a few IP in the configuration?Simple Direct answer: ImpossiblePlease refer to: #option_mysqld_bind-addressThe MySQL serv

When we use Linux to set up Web servers and FTP servers, we may encounter the need to implement multiple sites on a single service (virtual host), in which case we can increase the physical network card to solve. But how many extra slots do we have on our servers? So we can do this by binding multiple IP addresses to a network card, so let's look at how to bind

If a host is bound to have multiple IP addresses, then in the passive response and active initiating connection two ways, the source IP address selection mechanism is certainly different.
When the host receives the external packet and sends the response packet, the response source address is clearly the address of the client request, which is very easy to un
