I was just wondering if there was a way to find out, which processes were active at what time and more importantly when a certain process ended. Is there a log for that? didn't find any.

I know this is more of sugarcrm or php or apache problem but I would like to track the problem.
forums so I'm not sure this is the right place for this topic.So, my question/topic thing is:I have a PHP script that runs on an apache2 web server (www-data).From this script, i want to launch a process that stays alive all the time,ut the parent script keeps on going. So I think I will need to run a command like 'at' to put the process on a queue, and the script can continue and finish, without waiting for the process to stop. But it seems like I will need to run the 'at' command as a different user, because www-data stops the 'atd' process. I'm not sure about that. Does anybody know how this could happen?

I currently have sendmail installed. It starts as a daemon but I want to avoid doing that. I want to start it manually.Also am a dynamic host.so every time i start my computer my ip changes. I use ddclient to update my records at dyndns.com.but how to configure sendmail in the case of dynamic hosts since it looks at the file /etc/hosts which contains information about the static hosts.
View 2 Replies View RelatedI've just installed subversion.I need to create a script /etc/init.d/svnserve that will start at boot time.I want to use start-stop-daemon --start so I can track my process and eventually kill it using start-stop-daemon --stop.My problem is that I can't get it to work and the documentation shows no exemple.
I've replaced $DAEMON by the whole line: svnserve -d -R -r $REPO_ROOT and got -d is not an option.I'm not quite sure what to do at that point. If someone has some experience with start-stop-daemon it would be great.
Currently have access to a VPS where we are running a small game server on ubuntu - the problem is that it is a multi-user environment, so when one person restarts the server process, all files it creates are owned by that users name and group. I have created a group called 'game' and added both users to it, but I need to know how to make all files in the game server's directory to be r/w/x for the group 'game'. Currently, I have a script that chowns and chmods all files recursively on startup, but I'd prefer not having to do this.

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.
I'm having a problem with NFS. I'm trying to mount /home, which is on the server, to the client nodes. The server is currently running FC14 (64 bit) and I'm in the process of updating all the clients nodes to the same OS. Currently, all the client nodes are running FC8 (32 bit) and are capable of mounting /home on the server. However, the one client node that I have updated to FC14 is having problems mounting /home. I can ssh to the node with no problem however I get the following message:
Could not chdir to home directory /home/myuserid: Permission denied. Now, if I excute the following command: "sudo mount -a" I get no errors and now I can see my home directory.

I am in the process of setting up a couple of virtual servers in a cloud environment. I am currently working on my application server (Server 1) and am stuck on the creation of my ruleset for this server.
I need to allow SSH, FTP, HTTP, HTTPS, and PING on this server. This server will also need to be able to talk with a couple of database servers as well as a memcache server (all internally within my cloud environment)
I have been reading on iptables, since I have never messed with them before, and have come up with the ruleset I will paste below. I have taken other steps to secure my server...changing ssh port, not allowing root to login via ssh without logging in as a user, turning off unnecessary daemons, editing my hosts allow/deny files, just to name a few.
I am a newbie to iptables, so I would love a bit of helpful advice, criticism, and even a good explanation why I should add or remove or edit something. I really want to know the how AND the why!

Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.
as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.
