General :: WOL - Send Magic Packet?

Apr 1, 2011

As i am posting in this forum you might already have guessed that I am a total linux noob, but I am a pretty faster learner. I know a few basic things but I feel like I am stuck with my problem.I want to send the Magic packet (wake on LAN) from my linux machine to another, but I am unsure how to approach this. I have google�ed my ass off but I am none the wiser. I found a few forums posts and programs that can do the trick and guides in how to use the programs but I have no idea how to install them.You have to know that my linux machine is a NAS server and has therefore only Konsole access (no GUI). As I said before I am pretty much a noob

Ubuntu :: Magic Packet Received / But Wake On Lan Doesn't Work

Oct 15, 2010

I am trying to remotely wake up my computer. I am using the wakeonlan tool as follows wakeonlan -i 146.x.x.x 00:0f:.I have used wireshark on the remote computer and verified it was getting the magic pack. wireshark sees the packet, and immediately the remote computer sends an ICMP dest. unreachable (port unreachable) packet back, although I assume that is normal.On the remote computer, I used ethtool so I am enable to verify that suports wake-on is set to "g" or magic packet.

I believe that wake-on-lan is enabled in the bios. I have a hp dc5000, so I turned on S5 wake on lan in the bios. However, the computer does not wake up.My assumption is that once the computer is off, the router doesn't know where to send to packet because that ip is not there anymore. Does that make any sense? What other troubleshooting steps can I take? I don't have control over the routers though.

General :: Ubuntu: Give Sftp Root Privilege To User?

Sep 18, 2010

This is my first thread ever to make on the linux forum, and I just began using linux Ubuntu Lucid for my server. Please bare with me because I think I am questioning such a basic question. How do you give sftp root privilege to user? I've made group "admin" and made 2 users under that group. Trying to upload a file onto a server using SFTP with one of the user and it fails and says "Permission denied."

I gave full sudo/root permission to the group "admin" from /usr/sbin/visudo I mainly use Tranmit4 but I also have filezilla. Or is there a way to run sudo command on either ftp client application?

General :: Dreamlinux - Root Says 'superuser Required' While Installing FROM Root

Apr 21, 2011

I am trying to install google chrome on my computer, it is in a .deb package and I am using dreamlinux. Earlier today I installed a .cbr/.cbz file reader from root, that was also a .deb and it worked just fine. now I go to install google chrome and it says (Blue is my command, and red is the system response):

I checked under my USER GROUPS and Root is still set as root, and I haven't been using it unless I need to install with it to other directories, Should I be using another command to install? or is it a problem that may affect other aspects of my system? ... My biggest concern is not getting google in, I can wait for that ... I just wanna know why ROOT is under the impression it's not a superuser.

Fedora :: Missing Root Privilege Key Thingy

Apr 8, 2011

When I started using Fedora (with Gnome) a week ago, I noticed a key symbol in the system tray, or however you call that in the linux world ;-). I can't remember what it was called, but it appeared after I loaded a program or administrative function that required root privileges. If I understand correctly there's a certain timeout after you put in the root password that allows you to run more than one program with elevated privileges so you don't have to put in the root password all the time. I remember reading somewhere that you can change that timeout. This key symbol basically was a "screw the timeout, i'm done being root".

This key symbol doesn't appear anymore though and I'd really like it back.
I'm pretty sure, I didn't do anything to make it go away, as I didn't play around with any security settings.

It was a little tricky to search for this as I can't recall the actual name of this... key thingy..

Red Hat / Fedora :: Determine Network Interface That Will Be Used To Send Packet For An IP?

Apr 9, 2010

I'm writing to you because I encountered the following problem. My program displayes all network interfaces that are available in the system, but I would like to adda functionality in which a user can enter a destination address IP (ex. the IP address of the Google search engine) and will get information which network interface will be used to send it. As I know it is associated with reading information from routing table in the system. Maybe you know the API (functions/methods) which I could use to do it in RedHat ? I program in C/C++, but if you know how to do it in other programming languages (Java, Perl, Python) I will be grateful for any information.

Programming :: Send A UDP Syslog Packet With Source Port Set To 514

Jan 25, 2010

I am trying to generate a UDP syslog packet from my C application. But I am facing a problem with a Cisco Router ACE that does not like the Source Port being '0' and thus drops the packet.How can I specify the Source Port in the UDP header to '514' as stated in RFC3164 (Section 2: Transport Layer Protocol)? "It is RECOMMENDED that the source port also be 514 to indicate that the message is from the syslog process of the sender"

Programming :: Perl - UDP Server Receive / Send Packet To Host

Apr 1, 2010

I have found many examples out on the www for creating udp servers with sockets. The problem I am running into is after I receive the packet from a host I need to be able to send a custom made packet(I'm using RawIP / NetPacket to make my packet) back to this host. The only way to do this is seemingly through the send() function. This function however doesn't appear to allow me to specify which host to send my packet to.

General :: Send An Email From Root Console Using A Non Created USER?

Dec 29, 2010

I scan a document with root pressing the scanner button. I would like to send an email using my gmail account. OK. nothing difficult with that... mbsmtp + mutt for sending trhough the sh script.

1-root is to be avoided at max to do some internet duties, due to security. Apt-get is good, but ok surfing or email sending shall be avoided for higher security.

2- sudo or su running mutt through this way, ok, using an existing user. OK, possible and simple, but not comfortable since you have to use an account of an user existing (create a new user for scanner and email?? - no, come on, we have linux and can maybe find a solution)

how to send an Email from root console using an non created USER?
