Hi everyone
Im new to list and this question may be out of place. This is my first
post. Im new to freebsd and trying to understand how to create a jail from
some system calls. I followed the jail subsystem description from the
handbook and im having a problem or may be using the call incorrectly. But
here is what im trying to do.
int main()
{
struct in_addr ipaddr;
struct jail myjail;
char path[PATH_MAX];
realpath("/tmp", path);
myjail.version = 1;
myjail.path = path;
myjail.hostname = "testjail";
const char *ip;
ip = "192.168.1.142";
inet_aton(ip, &ipaddr);
myjail.ip4 = ntohl(ipaddr.s_addr); // I get and error here, invalid
conversion from _uint32_t' to in_addr*
myjail.ip4 = ipaddr.s_addr; // and and error here, invlid
conversion from in_addr_t to in_addr*
}
I know that there is more that needs to be done but this just a test stub
as im trying to work thru the calls and understand whats going on.
Any would be appreciated thanks.
Take a look at the jail(2) man page:
The ``ip4s'' and ``ip6s'' give the numbers of IPv4 and IPv6 addresses
that will be passed via their respective pointers.
The ``ip4'' and ``ip6'' pointers can be set to an arrays of IPv4 and IPv6
addresses to be assigned to the prison, or NULL if none. IPv4 addresses
must be in network byte order.
So you'd do something like the following:
myjail.ip4s = 1;
inet_aton(ip, &ipaddr);
myjail.ip4 = &ipaddr;
You don't have to switch byte order.
and in that case of 7.2-R or later multi-IP jails the version should
not be 1 either.
I fixed tools/regressions/priv the other day; maybe this helps a bit
as well:
