I have currently 7 servers that report logwatch every day.Fact is that it's lot of information to process every day, I would like to have as short as possible overview of events happened in last 24h is only critical/warning information . It would be + if all servers output could be gathered in 1 email
View 2 RepliesI've installed Ubuntu server on a small box with a couple of large hard drives to use as a remote backup server. Since my backups will run nightly in the wee hours, I'm configuring this to use Wake-on-LAN to start the server and run the backup. Once the backup completes - probably on the order of an hour later - another script shuts the server down. Once in a while I'll remote in to update packages and check on the status of the system, though I can check backup logs to insure that is still running.
Need I be concerned about the various cron jobs that periodically run to tidy things up? Should I periodically - say once/month - leave the system up for a full day to make sure that everything that needs to happen will run?

View 8 Replies View RelatedI'm looking at setting up a couple automated systems: Here are a few examples:
* Internal accounting system to download and process emails
* Public web server to visit
I could put each system on its own separate box -- for example, it's generally good practice to separate anything that external users have access to (such as a webserver) from internal processes such as accounting. Now, rather than dishing out the money for two separate servers, could I get away with just installing new instances of VMWare on the same box for each system?
To give you an idea, these are not large scale computationally sensitive systems. The accounting one is simply downloading and tallying emails, and the latter is just a webserver with maybe 5 hits per day on a good day. I could definitely pick up a new box for say $50, but I wanted to know the general practice of using VMWare on the same box versus two separate boxes.
jack uses 2 ports for input and 2 for output. I have a SoundBlaster 5.1vx card, and I would like to use a "line-out" plug for monitoring. But when I try to get jack to reserve four extra outputs by using the switch "-o 4", it gives me an error.

View 3 Replies View RelatedGidday, for some reason some of my RHEL servers don't send out a daily logwatch email (most do, but two don't) - and sadly I have no idea how to troubleshoot this.
Can anybody give some help/hints as to where/how I may troubleshoot this. I should add that these servers can/do send emails (I have some cronjobs that fire off emails upon completion of their jobs, so I know its not a sendmail config issue).
I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
Does anyone know the trick to getting Logwatch to make its entries a little less chatty and leave out the "Detailed" section of the Postfix report? I can't seem to tone it down and the daily reports I get include every recipient, host, etc., which is too much info to make a summary report useful.The first portion I get looks like this:
****** Summary *************************************************
9 *Warning: Pre-queue content-filter connection overload
2 SASL authentication failed
432 Miscellaneous warnings[code]....
This would be fine for a quick review that I do first thing. However,the "Detailed" portion that follows is over 2,800 lines long!
I've suddenly stopped getting emails from logwatch which runs on an Ubuntu server daily using cron.After a good day or so of troubleshooting, I was able to establish that it was the 'Service = named' line in my logwatch.conf file, which was stopping the emails from coming through. If I commented out this line, the logwatch emails come through with no issues, uncomment, and I don't get an email. I don't get any error from logwatch itself when I run it, even with '--debug high', leading me to think that my email configuration is setup ok, at least. Furthermore, I tried running logwatch with '--output file --format html' and logwatch produces a valid html file.
I then thought: "Could I have a entry in my Bind/named log files which could be rejected by my ISP's smtp server?". So, (to the best of my knowledge) I cleared out the log files in /var/log that contained messages from named. I then ran logwatch (including the named service in my logwatch.conf file) and I got an email through, with a pretty much empty named section, which is exactly what I anticipated. Great! - it's fixed.
So, the cron.daily ran early this morning, but still no email in my inbox when I got up. I then tried to run 'logwatch --Range today' and lo and behold, I got a logwatch report email, which included a named section, with log entries in there. So it seems that something that's been logged by named overnight to my logfiles (i.e. '--Range yesterday') has caused issues again with logwatch's ability to send reports through my ISP's smtp servers.
I occasionally see messages in my logwatch report then cannot find the actual log entry. Is there any way I can have logwatch give a clearer report?an example:
vsftpd:
Unknown Entries:
authentication failure; logname= uid=0 euid=0 tty=ftp ruser=a-specific-user

I need to set Nagios and permissions. I get one critical error in Nagios regarding disk. It says:

I have 10.04 desktop basically running xbmc sabnzbd and as a file server. the loads aren't too large as it is just for my house. But i moved from a server install to the desktop because of sound issues and running xbmc at start was a bit of a pain... so bit of background done.
My problem is that after installing 10.04 i got the disk utility pop-up saying one of samsung spinpoint 1tb (HD103UJ) has a critical error... now i didn't panic (although in the next couple of months i am intending to get another drive) but in the meantime i am simply wondering if this is a false flag? i've been getting this error for over 6 months now... pretty much from the last time i formatted the disk, i wiped it and then used dd to copy over a smaller partition, after which i used gparted to grow the partition to the whole drive. could this have created a false flag?
The 184 error is the only one, here is all the data i can glean from my system, attached is a screen of the relevent info from the disk utility, and this it from smartctl:
Code:

View 7 Replies View Relatedby now I have 10 servers for hpc, power computing oriented. My users need to launch several processes using qmake. The users are used to work with ubuntu 9.10, and the software from the repositories is switable for them. I've deployed ubuntu 9.10 to all 10 servers (pxe rocks). By now we work with parallel-ssh and cluster-ssh, which allows as to launch the same process to all servers. With this tools this tools the servers remain as independent but with the same software and the same launched command. Now we would like to go to next step and see all the servers as a single one with all the resources from the other 9 as if was its resources. The difference would be substantial in time to process and also time to design the command to launch.

View 2 Replies View RelatedI'm curious how I can use a Windows client with two separate accounts to connect, at the same time, to a SMB server hosting two shares. (Provided permissions and accounts are all in order)

View 3 Replies View RelatedMy ISP blocks outgoing email if it does not login properly with a valid account. I successfully configured sendmail to use SMART_HOST and confAUTH_OPTIONS with confAUTH_MECHANISM set to LOGIN PLAIN.
It successfully sends email because I tested it with evolution sending through 127.0.0.1, but I need to specify myacount@mydomain.com as the email address for root.
But it doesn't work for logwatch because it sends as from root@localhost.localdomain, and my ISP's smtp server rejects it. The message I get back in root@localhost account is the following:
