General :: (13)Permission Denied: Make_sock: Could Not Bind To Address 0.0.0.0:80

Sep 14, 2010

I want to let a regular user (not just root) restart apache on my Ubuntu machine.I was using /etc/init.d/apache2 so I figured this is what I have to set permissions for. I set the owner group for this file a group to which that user also belongs. I set the chmod to 775 but it didn't work. I then even set it to 4775 thinking this would totally make it work but it still didn't.I'm obviously giving permissions to the wrong file.

The error says:

Quote:

httpd not running, trying to start (13)Permission denied: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs But I didn't find httpd anywhere on my machine.

Ubuntu :: Android And Chrooted - Mysqld Can't Create Ip Socket Permission Denied

Sep 1, 2011

I have a droid phone, and I have ubuntu 9 running on it. This is done by chrooting since the phone runs a linux kernel. And it works... I have a question though. tightvncserver does work, and its able to listen on 127.0.0.1.. Its how you view your X session. So you chroot to Ubuntu, then start vncserver. Then switch back to android and login to ubuntu via vnc client. but apache, mysql, and postgresql do not work. Well. They dont seem too.. except for mysql. Mysql will start but only if you tell it not to use networking by saying skip-networking in my.cnf

Mysql says: mysqld cant create ip socket permission denied Apache2 says it can find 127.0.0.1 but doesnt actually run same with postgresql... All seem to be compiled with arm architecture. So why does tightvncwork? Why is it so special? How can it listen on the loop back (127.0.0.1) when nothing else can...

I have /proc and /dev bind to the chroot side. I can run ifconfig okay, and I can run /etc/init.d/networking start okay.. But apache2, mysql, etc have problems binding. I have removed apparmor even though technically its not running, but I removed it and its configuration files, just because I thought perhaps mysql looks at apparmor, but I doubted it.

Ubuntu :: Ssh Permission Denied (publickey) Bind To Port 22 On 0.0.0.0 Failed: Address Already?

Jul 19, 2011

I'm trying to add a key public key for my dev box which is a vm running ubuntu natty, and I am unable to connect via ssh. I've tried rsa and dsa, as well as these commands:

exec ssh-agent bash
ssh-add ~/.ssh/id_rsa
ssh-add ~/.ssh/id_dsa

I think I've found the error by running sudo /usr/sbin/sshd -Dd, but I'm not sure how to fix it:

OpenSUSE :: Traceroute Broken In 11.4 - Unable To Create ICMP Send Socket: Permission Denied?

Apr 5, 2011

Code: # traceroute -I 69.12.32.2 Note: the -i and -I options were exchangedfor compability with LBL traceroute Use -I for ICMP, and -i <ifname> to specify the interface name unable to create ICMP send socket: Permission denied Note that the command was done as root. This worked in 11.3.

And yes, it works without the "-I". But it should work with the "-I". One shouldn't have to boot into Windows, just to run "tracert" there.

Programming :: CSH Permission Denied When Accessing Local File

Mar 9, 2011

I've just recently started learning shell scripting and I've been working on a basic csh script, but I've been having a few problems. Here's the script

Code:
#!/bin/csh
echo Enter a file name
$< = FILE ##Name of file
echo enter a size (in kilobytes) to monitor
SIZETOMON = $< ##Size value that's input by user
du -k $FILE = $SIZE ##Size of the file that the user wishes to monitor
while (1)
if $SIZE > $SIZETOMON then
echo ALERT: File size is greater than $SIZETOMON
end

And here's the output
Code:
/home/lucer/foo.txt: Permission denied.
Badly placed ()'s.

I'm not really sure what the issue is with the "badly placed ()'s" or why it won't let me access files that I can access with the same shell when it's not in a script.

General :: 'Could Not Chdir To Home Directory /home/[user]: Permission Denied'

Jan 6, 2010

I have a secondary disk which holds a /home directory structure from a previous install of Linux. I installed a new version on a new primary drive and mounted this secondary drive as the new /home. Problem is, even though the users are the same names and I can access the home directories for the users, I cannot login directly to their home directories, as I get the following error: -

Code:

login as: [me]
[me]@[machine]'s password:
Last login: Wed Jan 6 18:34:33 2010 from [machine]
Could not chdir to home directory /home/[me]: Permission denied
[[me]@[machine] /]$

Now, since the usernames are correct and the users are in the passwd file with the correct home directory paths, could it be user ID's that are different or something else? It's not as though I cannot access the home directories for the users, simply that I cannot log directly into them from a login prompt.

Networking :: Can't Bind Send Socket: Address Already In Use

Feb 23, 2009

I am currently trying to get a B.A.T.M.A.N mesh network up and running. the thing uses UDP port 4305 for broadcasting to nearby nodes and it seems this port is closed or used by something else.

now i have tried to open this port with commands like

Code:

iptables -A INPUT -p udp --dport 4305 -j ACCEPT
iptables -A OUTPUT -p udp --dport 4305 -j ACCEPT

it still gives me the same error saying the socket cannot connect.any way for me to scan that udp port, see what is blocking it and open the thing up ?

Networking :: Raw SCTP Socket Cannot Bind With Port?

Jul 26, 2010

If I open a raw SCTP socket, am I able to bind to a specific port? (I only want to see SCTP packets from a particular IP address AND port.) Or, any raw SCTP socket, regardless of port binding , will get all SCTP packets received by the OS from that IP address? The port doesn't matter and is ignored.
