General :: Using Route Command With A Non Root Process?
Sep 15, 2010
I use the system command route from a process (using the system() call). For security reasons the process does not have root privilege and for some reason I cannot use ioctl() either. I tried to set the capabilities of the process to NET_ADMIN and SYS_ADMIN but the route command still failed due to insufficient permissions.
What are the capabilities that I need to set for route to be successful?
I got this definition:"a process that replaces a series of related, specific routes in a route table with a more generic route." honestly I found it not so clear.. I want to know if this definition is correct and also more details about this subject..
I am using this command for blocking some ipaddress. but now i want to remove iapddress. when i try # route delete 64.126.45.122 SIOCDELRT: No such process
Is there a way to bind specific programs to specific network devices (not IPs, since I have dynamic IPs)?
For example, I wish for irssi to route through eth0 and w3m to route through eth1. Keep in mind these devices have dynamic IPs, so I cannot attached them to an IP.
The solution cannot be accomplished through route since route pivots on IPs not devices.
It's pid is increasing all the time... I'm writing a program to display all the process's info, this process really bother me. Oh..the Chinese words are sleeping..., can't use, can't use
I am trying to set the umask for a process(orkaudio) which is running as the root user.This program creates dir and files and I need the umask to be 022. I have edited my /etc/bashrc -- and when i type in umask i get 0022 --- Not sure how to go about getting this resolved...
I've some file with .sh extensions that runs some softwares.Now,how do I stop running that filesI know we run the command ./start_tomcat.sh to start the apache.Is there any command to stop that file/process or is it just kill the process to stop the process
I need to kill a process which has been started by user2 if I am user1 without being sudoers or using root.Do you know if there is a way of setting that when launching the process? Such as a list of users allowed to kill the process?
This causes Tomcat to be run as myuser, which is expected. However after issuing the reboot command the system starts up and root is now the owner of this process. How can I force the process to be started off as myuser on reboot?
i am looking for a detailed description of the login process for both root and normal user , also locally and remotely.i read some sentences that the files .bashrc and bash_profile are needed for this process. But that was very concise.
I have tried top and PS command but i am not able to find the RAM used by each process.top command says that 240MB RAM used but the Memory shows 0% for all the processes, same with ps. i want to know which process consumes all 240MB RAM.Is there any command which / script which can sort the running process in oder of increasing RAM usage so that i can see. Also i find it very hard to read bytes and KB. Is there any to way to chnage those units to MB
I have created three child process from one parent. And different child has different functions. Child 2 has got function to load file called "wc" to count file1 and and its required to get their files by command line arguments. I can get the files through command line but couldn't get the files when child 2 process start.
Is there any command in linux to figure out , given a process, which processor the process is running? I am interested in figuring out the CPU busy and CPU idle time of that processor.
I have a script that calls other scripts/commands which may or may not spawn other process. From my understanding, when I do a ps -ef, the highest numbered process ID is supposed to be the parent ID of all the other related child processes, is this correct? In most or all circumstances, I do a ps -ef | grep <processid> of my script and anything that spawns off that process IDs I assumed are the child processes of my script. If I want to terminate my script and all other child processes, then I kill the parent ID which is the highest numbered PID and this will subsequently kill all other child process IDs, is this correct?
Now, my question is whether there is any quick way of showing what are the child processes of a parent ID instead of what am currently doing now which is visually checking which one is the parent ID and "assuming" that the highest numbered PID is the parent ID of all the other processes. Below is a sample output of running ps -ef | grep exp | grep -v grep. I assume from the output below that the parent process/ID is PID 11322, is that correct?
I'd like to start a background job using the sudo command and route its output to a file. This presents a problem because the prompt for the password doesn't work properly. It looks something like this when I try it:
Basically I'm not properly prompted for the password and as soon as I type anything in my background job fails because it didn't receive the password. Is there any way to execute a sudo command by supplying the password on the same line as the command?
Because of my English skills I'll try to explain this subject as best I can, thank you for understanding. Fisrt of all, I am running some program on my slackware in background (using standard method - &). I need to make a script, which allows sending command to this process on my machine from another one. Furthermore this program have to be logged out (standard output f.e. ./myprogram > log.out.txt).It might be a separate Program A which runs my Program B but it cannot be screen, because it is not working like I'd like to and it cannot be java, because it's slow and working not the best so to speak
Is there any command to find out for how many Milli seconds a process is been running?s -a -o pid,etime | grep "process pid" gives the time in min:seconds. I wanted in milliseconds .
The first call to "somefunction" works as expected. The function prints "endfunction" and a process in background sleeps 30 seconds. In the second call I thought it should work in the same way, but the script sleeps 30 seconds before it prints "endfunction".Does someone know the reason of this behavior? Is there another way to do a command substitution of a function that has a background process without have to waiting for that process?
I write a script to read a file which is something like a pipe (or) queue , which shows the running status.In normal case, if i open this file with cat command, i have to use ctrl+c to exit this . What command shall i use to do the same inside a shell script ? I have tried ^C in my script , but it does not exit the process.
I do not understand this command well. Yes, I have looked at man route and that whilst that gives lots of information about the switches I cannot see it in context. I have a server with two nics. One to the Internet (eth1) and one to the lan (eth0). I use pppoe and when it is running I get a virtual adapter appear in ifconfic called ppp0 which shows the public DNS and ISP session IP. I entered the command: route add -host (gateway IP) dev eth1 and get the Internet to appear on the server. However, I do not get the Internet to the clients. I have turned off the firewall to be sure that this is not the problem.
