Basically, I go through certain logs on my linux hosts checking for anything out of place. You know, the usual, /var/log/messages, lastlog, etc. What I've been using is just a simplistic grep statement that looks for keywords in certain log files, such as warn, crit, etc., with the -i flag to ensure no case searches. I thought, well, surely there are others out there doing the same thing, but more automated. Perhaps something that can check files for keywords and then notify, via email, if anything out of the ordinary is seen.
For a certain task, everytime I have to open 10 bash terminals and write different commands on them. Any way to automate this? I am running Fedora linux.
I need to copy all subdirectories and files from one directory to another ever 5 minutes or so, with the old data automatically being overwritten with the new data. I'd also like this to run at startup. Is there any way this can be done? If so, what program would I need to schedule the automation and what is the command line I would need.
here is the thing. I've deployed BackupPC in a server at work, and everything is working fine. Now, what I need to do this thing. I have a remote server with a website and a postgres db running. I've been able to set up everything to be backed up using rsync. But I would like to make the same process to restore the backup immediately in a local server trough rsync, that has to be ready just in case of failure of the remote server. What I've tried to do is to run the DumpPostUserCmd, so whenever a dump is performed in the remote server, I can have my local server updated. What I've find out is that when you perform a restore through the web interface, the command that performs it is (using ps ax in the backuppc server):
So, what I could find out is: /usr/bin/rsync is the command that the process runs in the server where I want to put the restore. Then the options, and finally, source and destination of the restoration. But, as you can see, the source is '.' but I cannot guess where to point that!
The question that I am posting here is quite interesting as it was asked in the interview I attended today. And, honestly, I could not provide a solution. Ok, here goes the problem statement:Design a Web Interface that has three text fields:
IP Address: Subnet Mask: Default Gateway:
And a button:
When we click the Submit button, the two entries must be set in the concerned files and then the network service must be restarted to bring the new IP Address, Subnet Mask, and Default Gateway in effect.As we all know that these settings can be done by the root user or a user who has those priveleges.The complete web interface needs to be done only in PHP. Some Shell Script can be used if required.
Here's the setup: One x86 server (Red Hat 4) with two serial connections to an embedded linux device. One serial connection is to a power control so the device can the restarted, and the other is used for a console to this device. Both serial connections use minicom. People on my team VNC to the x86 server, where they find the two minicom sessions waiting for them as they are left open. I would like to automate connecting to the server and communicating over the serial lines.
Supposing I use ssh to the x86 server, could minicom be used over the serial lines without terminating the minicom processes seen through VNC? If not, is there a way to re-open those windows from within the ssh session, so a user who VNCs to the server won't have to reopen them? Could a single ssh connection control two minicom terminals simultaneously, or would there need to be two ssh connections? It is assumed a user and the automated process will *not* try to access the device at the same time; the automation would trigger during off hours.
Anybody knows how to fix overlapping tasks in KDE system taskbar?Here System Monitor overlaps with digiKamWorkaround to rearrange icons - start any new task.Sorry for taking real photo of the screen. When I do PrintScreen KSnapShot task appears in the list and makes all task to rearrange. The resulting screenshot contains already fixed view.
After upgrading from 10.10 to 11.04 all of a sudden, the task manager or task bar, keeps changing length. The individual window "buttons" themselves keep changing size - flashing even, and the space between them also changes. It is driving me nuts! The little system tray(?) icons no longer appear in the system tray, but all stacked on top of each other in the top left corner.
How do you launch a task from a terminal command line interface and it not be kill'ed if you close the terminal window. Like if I run jedit I type jedit & which launches jedit as a backgorund task. But, if I close terminal window, jedit dies to. How do I laucnch jedit and completely divorce it from the terminal task?
I used to have a log file monitoring script on my server but after an auto update recently it seems to have disapperaed.Can anyone think of some log file analyzers that send outputs of ssh, amount of disk space used etc. as I cannot remember the name of the program at all.
I want to monitor RDS (mysql database of EC2) using Nagios. In command line ( I am able to do it but I dont know how to feed it in nagios . On nagios server if I execute the following command , I am able to fetch the information of database (RDS)
I want some users should be barred from login into some of NIS clients. Please help me to accomplish this. I googled it but still not very clear to me. Can you please tell me how it works. The OS is RHEL 5.
I was looking for some software to run on my Debian vServer which monitors RAM, CPU and HDD usage. This tool should not require Gnome/KDE, so I guess I'll end up with a PHP tool. I did some search but came up with nothing. I'm using Parallels Power Panel (there might be a plugin or something like that?)
I am using CentOS 5.4 and did a yum install of cacti. I installed all the necessay packages, like net-snmp, php net snmp and all that. Everything else works but I can't for the life figure out how to monitor traffic on eth0. I do not have any SNMP Interface Statistics or alike in either the Associated Graph Templates or Associated Data Queries.
Heres the output of "snmpwalk localhost -c public -v2c" , SNMPv2-MIB::sysDescr.0 = STRING: Linux xxx.xxxx.net 2.6.18-164.6.1.el5xen #1 SMP Tue Nov 3 17:53:47 EST 2009 i686 SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-MIB::netSnmpAgentOIDs.10 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (7515443) 20:52:34.43

I am trying to monitor the interfaces on the local computer only.
I want to know which was the best networking monitoring tool in linux wright now im using opennms . i like to try out with any other monitoring tool can somebody say which one is best one followed in linux industry
I have my task list in evolution (mainly so it can sync with my phone and online task list) but I always forget to look at the task list. Is there an application or plugin which periodically displays the contents of the tasklist or even better, it briefly displays the most urgent/important tasks when I login? Or anything else which automatically displays the most important tasks. Currently I have to open the task list and look at them (which I usually forget). I do not mean some kind of alarm when the task is due but more a daily reminder of what to do.
Is there any trick to make a user's interactive shell captive inside my intended shell script after login, or else logout? i.e. Mr.Naughty can never make to the command prompt to do something nasty.
Can you provide some form of monitoring on this server or recommend any server-side applications that could monitor the status, in high detail, including traffic, etc?
I'm running a Debian/Samba PDC on a Windows network. We desire to monitor a few network shares, so that whenever a change is made to a file in those, we have a log of who did it and when. Some capability of seeing what the change was, or a way of reverting it, would be nice luxuries. But username and timestamp are most important, if possible.
On the debian forums, someone advised using Tripwire for this purpose. didn't give much other advice about it so I kind of struck out on my own researching tripwire. got it installed, played wth it, and found it problematic, to say the least. It seems a bit much on the complexity and security side, and it seems more oriented towards maintaining system integrity, than monitoring documents. So far I've not managed to get a policy update working on account of a cascade of errors about a few hundred files under /proc disappearing, despite no changes to the system.so I'm wondering if anyone here has advice.
1. Does debian have this sort of functionality built in? is there a system log I can parse to get this information? 2. Is tripwire the right application for our purpose? 3. Is there anything better suited, more user-friendly or more parsimonious. I don't need something to monitor all system files, guard against intrusion, and make me cups of tea, just to monitor a few folders that I specify
I am looking for some monitoring tools (such as disk usage,memory usage, cpu,etc) for my linux machines. I came across two tools, cacti and splunk.Which one is better ? It will be nice if you can also let me know the reason.
I'm looking for some sort of a way keep track of all of my users that are logging in to my server (centos 5), what I mean is this: at our firm we outsource some of our work (programing), now all of the developing is done under our servers, what I'd like to find is a way of taking all of the users log on time and display by days/weeks/months - so I could see how much did everyone had put in. Another thing that I'm looking for is a way to monitor an ongoing session and record user activity, now I've seen ObserveIT, but it doesn't support Linux agents as of today.
I'm looking for commandline monitoring tool for mysql and only thing I can find is mtop. Unfortunately, mtop's development halted back in 2004. Can someone suggest an alternative? or is there such thing?
I need to monitor resource of my server.I have found munin and sysstat, Does munin use systat? or they are different package?because in some documents I have found on net,for installing munin, systat is needed !!for example on RedHat based distor, sysstat package is needed! but on debian is not needed
I'm looking for an application that can run remotely to periodically check a webserver to ensure that it's delivering pages. I can't use one of the free web-based services because the servers I'm monitoring are closed to the outside internet. I have internal client machines I'd like to install the monitoring tool onto that can check specific URLs in both HTTP and HTTPS. Then email a notification when something stops responding. It would be nice to have a tool that is platform agnostic (written in perl, python, etc.) so I could have flexibility in what type of client machine I use for the monitoring.
We have few servers and we need to monitor mysql and ping (port 80) on our servers to send us email notification and also we need sms notification when something is wrong, we can ask our developer to write sms notification (which is very important for us) because we already have the API and only need a output from a good monitoring tools to show to our developer and ask him to write the notification program.
Our primary sever is centos with WHM installation and hosts about 600 websites.(need to monitor mysql & port 80 on this.)The secondary one is windows server with virtuzzu installation and host about 15 windows VPS (The server crashing some times and we need to findout its out of service ASAP .)Should we use monitoring websites such as hypersins.com or siteuptime.com (which is a little expensive for us especially because of international sms rates.) or there is nice tools we can easily configure and use !
I see tons of these in my dmesg, and it's causing my virtualbox vms to crash with disk IO errors. It's only affecting the Linux guests. What would cause this?
Code: INFO: task tar:1865 blocked for more than 120 seconds. "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
