connect() parameters or maybe something else.
I'm having trouble when running a program that uses the connect(). I keep receiving errno: 22. Below is the code that I am using.
Do I have the variables set up correctly?
Am I passing the correct parameters?
I have been searching for source code on the connect function but haven't found any. IF you know of some posted on the net I would really appreciate it.
-------------------------------------------------------------------------
int read_sold(char rxfile[], char message[])
{
int i, rc, s;
char hostname[64];
char readbuff[MAXREAD];
struct sockaddr_in sin;
struct sockaddr const fin;
memset(readbuff, 0, MAXREAD);
/*
*** Get TCP address and socket
*/
for (i = 0; i < 3; i++){
if (tcpaddress(&s, POSTORXPORT, &sin, (sizeof(sin)), message) == 0)
break;
if (i == 2) return -1;
}
/*
*** Try to connect to the address
*/
for (i = 0; i < 3; i++) {
if (connect(s, &fin, sizeof(fin)) < 0) {
if (i == 2) {
sprintf(message, "Client CONNECT failed: errno = %d",
errno);

virt-viewer
VIRT-VIEWER(1) User Contributed Perl Documentation VIRT-VIEWER(1)
NAME
virt-viewer - display the graphical console for a virtual machine
SYNOPSIS
virt-viewer [OPTIONS] DOMAIN-NAME|ID|UUID
DESCRIPTION
virt-viewer is a minimal tool for displaying the graphical console of a virtual machine. The console is accessed using the VNC protocol.
The guest can be referred to based on its name, ID, or UUID. If the guest is not already running, then the viewer can be told to wait until
is starts before attempting to connect to the console The viewer can connect to remote hosts to lookup the console information and then
also connect to the remote console using the same network transport.
OPTIONS
The following options are accepted when running "virt-viewer":
-h, --help
Display command line help summary
-V, --version
Display program version number
-v, --verbose
Display information about the connection
-c URI, --connect=URI
Specify the hypervisor connection URI
-w, --wait
Wait for the domain to start up before attempting to connect to the console
-w, --reconnect
Automatically reconnect to the domain if it shuts down and restarts
-d, --direct
Do not attempt to tunnel the console over SSH, even if the main connection URI used SSH.
EXAMPLES
To connect to the guest called 'demo' running under Xen
virt-viewer demo
To connect to the guest with ID 7 running under QEMU
virt-viewer --connect qemu:///system 7
To wait for the guest with UUID 66ab33c0-6919-a3f7-e659-16c82d248521 to startup and then connect, also reconnecting upon restart of VM
virt-viewer --reconnect --wait 66ab33c0-6919-a3f7-e659-16c82d248521
To connect to a remote console using TLS
virt-viewer --connect xen://example.org/ demo
To connect to a remote host using SSH, lookup the guest config and then make a direct non-tunnelled connection of the console
virt-viewer --direct --connect xen+ssh://root@example.org/ demo
