I am getting error 13 -> Permission denied because of user mode. If change from usermode to kernel mode everything works fine. I need to bind the socket in user mode only. Please suggest a solution while explaining the problem above.

SIOCSIFADDR doesn't bind a socket, bind() does. SIOCSIFADDR sets the address of the machine's network interface. –Robᵩ May 3 '11 at 15:50 1 Just a small nitpick: running a program as root is very different than running in kernel mode. Programs run as root still run in user mode most of the time; they just have elevated privileges. All processes (root or not) switch between user and kernel mode when they make system calls like ioctl. –Jay Conrod May 3 '11 at 16:13 add a comment| 1 Answer 1 active oldest votes up vote 7 down vote You can't set the interface address unless you are root (well, technically, unless you have CAP_NET_ADMIN). See devinet.c. The solution is to run as root. How to implement that solution, whether to make your entire program SUID, or ask the user to run it via sudo or gksudo, or whether to factor your program into two parts (root and non-root), that choice is up to you. share|im
show that you can learn something new everyday. I setup my secondary DNS servers for both revsys.com and my personal domain in the way that I always have. But I http://www.revsys.com/writings/quicktips/bind-permission.html noticed that the secondary was consistently getting the following error: transfer of 'revsys.com/IN' from 69.44.154.136#53: failed while receiving responses: permission denied From this error I assumed that my master ( aka primary ) server http://askubuntu.com/questions/338218/why-am-i-getting-permission-denied-make-sock-could-not-bind-to-address-when was not setup correctly to allow transfers from the secondary. This is normally done with the following configuration option: allow-transfer { 192.168.0.2; }; Where 192.168.0.2 is the IP address of the secondary (slave) DNS permission denied server. After I had double checked this configuration on the master to make sure it was there and that I had not done something dumb like typo the IP address. On the surface everything seemed to be perfectly setup, but I was still getting the error. Eventually I realized that the error was not a permission denied error from the remote master server, but from the local bind permission denied DNS server. The error turned out to be a file permission error in the default layout of BIND on a Fedora Core system. Around the time of Fedora Core 3 the default configuration for BIND is setup to chroot the daemon into it's own filesystem space to help avoid and contain any security breaches. This is a great feature. To fix your permission denied error on your secondary or slave DNS server all you need to do is change the permissions of your data directory to include group write permissions. On my system that directory is /var/named/chroot/var/named/. You can do this with a simple: chmod 775 /var/named/chroot/var/named or chmod g+w /var/named/chroot/var/named It should be noted that you will only run into this error on a secondary or slave DNS server if you have the secondary store it's slave information in a file. This happens when a slave is configured like this: zone "example.com" IN { type slave; file "secondary-example.com"; masters { 192.168.0.1; }; }; Another option, that in many ways is more correct on a Fedora Core system, is to store your secondary zone files in the slaves/ directory. This directory is in /var/named/chroot/var/named/ and already has the proper permissions

In Linux ports from 0 to 1024 are reserved for system use. This means that in order to use one, you must have the authority to change - access basic system settings. The root user has such privileges and can actually use a port from the range 0 - 1024. In your problem as you can see, the system through Apache2 response indicates the root of the problem ([...]could not bind to address blah blah 80): (13)Permission denied: make_sock: could not bind to address [::]:80 (13)Permission denied: make_sock: could not bind to address 0.0.0.0:80 When the Apache2 http daemon starts, it tries to bind the 80 port as it is the default port for use in HTTP see, which is a port within the system assigned ports and as such it can only be accessed by root. You executed the start
