On Linux, is root privilege required to send a wake-on-lan magic packet? If it depends on how you send the magic packet, please let me know under what situation root is required.

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
View 16 Replies View RelatedI 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.

View 1 Replies View RelatedThis 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?

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.

View 9 Replies View RelatedWhen 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..
I'm new to Linux (had some basic Unix experience in 1995 era). (Teenager) gave me HP2133 mini notebook running SUSE Linux Enterprise Desktop 10. Everything checks good (hardware and software), even wireless networking. Problem is she apparently created Admin/root password but says cannot remember. I cannot even set correct date time... yast is asking for root privilege:
Command: /sbin/yast2 time
Is there anything I can do to re-establish administrator privilege?

View 7 Replies View RelatedCan someone help me with this problem,trying to send a packet,using tcp/ip,the packet should look like this:
Code:
field 1: SOCKS protocol version, 1 byte (0x05 for this version)
field 2: status, 1 byte:
0x00 = request granted
0x01 = general failure
0x02 = connection not allowed by ruleset
0x03 = network unreachable
0x04 = host unreachable
0x05 = connection refused by destination host
0x06 = TTL expired
0x07 = command not supported / protocol error
0x08 = address type not supported
field 3: reserved, must be 0x00
field 4: address type, 1 byte:
0x01 = IPv4 address
0x03 = Domain name
0x04 = IPv6 address
field 5: destination address of
4 bytes for IPv4 address
1 byte of name length followed by the name for Domain name
16 bytes for IPv6 address
field 6: network byte order port number, 2 bytes
and this is my code:
Code:
int domainLen = strlen(domain);
char reply[domainLen + 7];
reply[0] = 5; // version
reply[1] = 0; // succed
reply[2] = 0; // reserved
reply[3] = 3; // its a domain
reply[4] = domainLen;; // lenght of domain
for(int j = 0; j < domainLen; ++j)
{
reply[j + 5] = domain[j];
}
reply[5 + domainLen] = 80; // port
reply[20] = '�';
Send(reply, sizeof(reply));
domain is "www.google.com". Am I doing it right ? I dont know much about bits.
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.
View 4 Replies View RelatedI 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"
View 1 Replies View RelatedI 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.

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)
