i am not familialized with Linux i installed recently a TACACS+ server under CentOS 5.5 and it is working well but my boss asked me to make a weekly backup of the tacacs.log file to check who was connected at any time the problem is that i don't know how tp make this backup and how to make it automatic and also he asked me to change the default port of tacacs from 49 to another port does someone knows how to make it?

It will start at the scheduled time and do the "search" part of it but it hangs before it creates the archive. These two processes (backup_cron & y2base) remains running and never terminates.
Here are the last few lines in the Yast log before it hangs:

Linux/Ubuntu noob here so please be gentle So I own an Ubuntu server (7.10 - "gutsy") which was previously used for my small business. All setup and maintenance of this server was done by an admin who has since moved on and I can't get in touch with.As part of the setup, this admin has somehow setup the server such that whenever I plug in an external HDD (USB) it automatically runs a backup script which copies over a whole bunch of stuff to this drive.I want to cancel/delete this script as this is no longer necessary. Can anyone give me any pointers as to how I could track down where this script is and how to remove it?
View 2 Replies View RelatedI wonder if anyone knows of a cross platform sync/backup utility that can do the following:
Incremental backups Revisioned backup (possibility to not just restore the latest but to go back to a specific point in time) Two way sync. E.g. two computers sync to the same server and the server also pushes changes to the clients (well I suppose it might be possible to solve it by restoring the latest backup also)
Cross platform: Linux, Windows & Mac (the server side may be Linux only)
Basically I want a revisioned version of Unison or a local version of Dropbox with support for custom folders. Depending on how you see it.
I'm not afraid to script things together if no pre-built solution exists but there are tools that when combined might do this. However it must be possible to automate, this comes from the fact that I want to be able to schedule it so it performs automatically. (If there is a way to push changes to the computers, like Dropbox, that's a plus but not a requirement.) This also means that a command line utility might be preferable over a GUI-only one.
I have been looking around online and I am seeing that there are several solutions for doing a nightly automated backup on Linux. I was wondering what people here actually use for doing such and why they use one particular backup method over another.
What I am looking to do is every night (at say 3am) I want my system to backup my 200gig Documents folder to my external hard drive. Does Ubuntu have a tool built in by default to do this or do I need to add something from the repos/online?
Currently, I would like to setup an automatic backup system, where the data on my computer is copied to an external harddisk which is connected to the router (Siemens SE551). This device theoretically allows setting up a file server, but unfortunately I can't access the share from Linux. I have not yet tried to access this share from Windows.
The rough plan is to use rsync and ssh, issued by a cronjob on both, my Ubuntu- and on my WinXP-notebook. But before considering this, I have to get my system connected with this drive.
BTW: I am using Ubuntu 10.4.
According to the SE551 manual [URL], NAS is not provided.
I followed this manual and set security OFF. According to the router's web interface, the device was recognized correctly.

After I spent some time discovering The BIG BANG of Universe and The Meaning of Life :
I managed somehow to create a script to make some backup of files on server and TAR it and then FTP the archive to another location FTP server and then emails result.
It also measures time needed to complete it and deletes archive older than XX days (set in find -mtime +20) and makes incremental backup every weekday and FULL on Sundays (which suits me bcoz no heavy load).
Files for TAR to include and exclude are in txt files listed each line separate name:
file: including.txt:
make /usr/bin/make all-am
make: Nothing to be done for `/usr/bin/make'.
make: *** No rule to make target `all-am'. Stop.
whats wrong with this???
I have installed CentOS 5.5 successfully and I have VNC working. This server will be a headless box that will reside in a server rack. I intend to perform any necessary maintenance on the machine remotely though my desktop computer. My problem is that when CentOS is on the login screen, I cannot connect with VNC. Once I have logged into a user account, then I can connect.
I would like the server to automatically login to one of my users each time it boots so that the VNC connection will be opened. Currently I have two users, root and Zachary. I would like the server to automatically login to the user Zachary.
In the CentOS Gnome GUI, when I go into System > Administration > Login Screen, and then click on the Security tab there is an option to "Enable Automatic Login." If you check this box a select form field becomes active; however, there are no user accounts showing in that select field. I tried typing in the user name that I wanted to automatically login, but after closing the screen it clears that username. What am I missing?
I installed CentOS 5.2 because I want to install the latest VMWare Server (2.0.1).The release notes of vmware server say: "Support for CentOS 5.2".But after installing CentOS 5.2 and updating the packages marked for update,the Version of the system is 5.3. I know from Debian that if you do not explicitly want to do a system version upgrade,only bug fixes and security fixes are installed. That seems to be different with CentOS/RHEL?
Is there any way (or what ist the right way) to prevent automatic upgrade from one release to another? I don't want VMWare Server to stop working because of some upgrade from 5.x to 5.y.
I've just built a fresh Centos 5.4 install on a 533 MHz P3. This machine is going to be used as a thick client on a LAN. I'm trying to implement automatic logons to the KDE desktop but the automatic logon implementation isn't working as expected. I'm hoping that someone can tell me what I've done wrong. Here's what I've done so far:
1. Created a non-root user account named "bob". "bob" has generic low-level privileges on the machine.
2. I've tried to enable automatic logons using the following GUI menu selections:
Control Center > System Administration > Login Manager > Administrator Mode > Convenience Tab

View 1 Replies View RelatedI run a few dozen dedicated web servers all running CentOS 5.5. A long time ago when one server was apparently compromised, I was urgently advised to sign in to the server and run "yum update" at least once a week to ensure that everything which I had installed using "yum", would get updated with any recently available updates, including security fixes, and that one reason I might have been hacked before was because I hadn't been doing that.
So, I'm still not sure if that would have prevented the original break-in, or how much this has reduced my chances of being hacked, but I've been faithfully signing in to each server every week for the past few months and running "yum udpate". Most times, this results in a lot of patches being downloaded and applied, so it's clear the machines are not doing it automatically. I figure it's about time to learn how to make the machines do this on their own. Is there a standard way to make "yum update" run automatically, every day, or every week? Yes, I'm sure there are many ways to do it, but is there a single way used by the majority of webmasters of CentOS sites who have automatic updates set up? Googling a bit for "make yum updates automatic" turned up some threads like:
[code]...
in which people describe writing their own custom scripts to do yum update automatically. This seems odd. It seems like the kind of thing that there would be a standard way to turn on. Also, is there a reason that virtually every newly provisioned dedicated server does not have "yum update" set up to recur automatically? If it's true that people break into websites using exploits that have been found in older versions of webservers and other software, and that sometimes these breakins would have been prevented by the newest patches, wouldn't it reduce the number of websites being compromised if the OS had yum updates turned on automatically by default?
I'm trying to make my system automatically shutdown once the battery level is low, but still without success. I've tried kpowersave, gnome-power-manager, kpower, klaptop but none of these worked for me. Well, I can't imagine I would be that stupid, but simply it doesn't work. In all cases mentioned above (kpower, klaptop, gnome-power-manager) I've tried to setup the laptop to shutdown once the defined level is reached, but the laptop never actually switched off unless all the battery was drained.
Btw. I think all the above mentioned apps only work once the user is logged in. But I'd like the solution to work also when the PC is on without anyone logged in. I thought I could write a bash script based on parsing of acpitools output and define it as a service, which would monitor the battery level, but I simply don't believe there isn't any functional solution to this.
Next week we will get a new Server for rent with a preinstalled Debian. If we download the Networkinstaller and put it in Grub, it is possible to set some settings with a script or commandline? We need SSH and the Network haves to run. So we have to set up the Networkadress , Gateway and Netmasq. So if the Networkinstaller is booting that we get direcly access with SSH to install CentOS. It is possible?

(OS OpenSUSE 11.2) On the ./configure stage i've got the following error message configure: error: Could not find libwrap. You must first install tcp_wrappers. But libwrap library has installed already. I see this by the output of ls command within /lib directory

So i suggested option --with-libwrap=/lib could solve the problem. But it is not. Also i was tried make #export LD_LIBRARY_PATH=/lib with no result. The problem is still there.
I'm running CentOS 5.4 on a Dell Xeon PowerEdge 1850. I want to back up an RHEL 4x web/mail server, 2 WinXP workstations, and 2 Ubuntu desktops....and I want them to go to my Dell LTO2 tape drive. What are my best options? I want a series of incremental daily backups and then a different series of weekend full backups.
I should have clarified that this is all in a small office LAN environment and that the RHEL web & mail server is another PowerEdge 1850 that is co-located with the CentOS server (same rack).
I am planning to implement a backup strategy to backup my basic system ,applications installed and the different configurations also of the personal data (From documents , music etc , to my photos , 3d design files etc) I have a Hard disk (well SSD really) of 120GB for the system (8GB Swap,30GB / and 60GB /home), one 750GB Hdd for save my music,photos,images and other things not related to 3d design , and i am going to buy tomorrow 2 hdds more , one of 1 TB for use only for 3D design , for save final images , models , textures , 3d related documentation and like , and one 1,5 TB HDD to use as backup of the personal data and the system. (One 500 Gb partition for backup system, and hold clonezilla images, and one for backup the data for example)
By the moment what i have done , is use clonezilla to save a image of / and another image of /home in my other hard disk (I save a image of system installation in ext3 prior migrate to XFS , and later , one image with the system migrated to XFS) and i have used Rsync to copy both / and /home to two partitions in the other hard disk , so have a copy also of clonezilla images. I think use clonezilla ,is useful to do each some time,so be able to have a fast way of recover the system , but i would like to implement a daily or weekly backup of my data and system , for example making a full backup and then incremental backups.
Perhaps for backup data this is a good aproach , but for backup configuration files , and the system in general ? , i mean , if i backup the things while using the system , could some files being not backuped , because being used ?
If i decide to install,for example, my new Wacom Intuos4 M tablet, for that i need to install the kernel source , and compile some modules and things by hand (because repository packages of wacom are a bit older than need for new intuos4) ,that will change my system and add new libraries and files to it.
If i make a full backup , and then incremental backups , each some time , if i have a problem or make a mistake when installing it or doing something , i have only to restore the backups via live cd, no ?
But if some files are being used , that, will not be backuped, so when restore it , that files , will be modern versions compared to the backup (perhaps that files would not be later modified , but who knows) and i could have problems no ? Perhaps a solution is have a clonezilla image of the system prior the first full backup ,and restore it fist to have a new installation ,with all files , used included, and then restore the full backup of the 1h later ,and the incremental backups until the moment all gone bad , to have the system working again no ?
So i don't have to be worried by files used by the system as long as also of doing online backups , also have a exact image of my system , that will make me able to restore it in some minutes and don't have to install all , by hand and remember what i had installed. Also that lets me to backup only , at least when doing full and incremental backups , the directories of the system that are dynamic, and change , and those that are static , backup them only one time.
I have a CentOS 5.4 installation with 2 Hard Drives [Disk 1 and Disk 2]. I have mounted the Disk 2 as a ext3 partition called /backups within the OS installed in Disk 1 [other partitions on Disk1 include / and SWAP].
I have a CRON job that creates specific backups of Disk 1 onto Disk 2.
This works fine.
My Problem : I wish to move Disk 2 to a New Box on which Iam planning to load the same CentOS 5.4.
My Questions :
1. Will Disk 2 be immediately identified in the new install and I add it as another partition in the new install ?
2. Do I have to perform any specific set of operations to integrate Disk 2 into the new Box ?
3. this kind of migration of a Disk partition contained on a Seperate Hard Disk cannot be migrated to a New install CentOS Box ?
on my server I have atMail and a intranet site being hosted using mySQL for the database locally, and obviously backing it up would be a good thing. I got the backup package from the list if you use the add/remove software called dump-0.4.etc.. can't seem to find much on how to use it, set it up, nothing. Granted I could be looking for the wrong thing which I'm sure is the case. As of now it's looking like a USB drive is going to be my only option, that will change in the future as this "project" goes further (we are a windows shop trying out Linux, and the next step is going to be adding another server that's a file server at that point we'll probably go to NAS for the backup and then transer that to a USB for offsite/secondary backup).

Is there anywhere that gives detailed (suitable for non-experts) instructions on how to install rdiff-backup?
Only ancient versions seem to exist in any repository, which appears to rule out use of yum. Finding rpm packages also seems extremely difficult. And I'm not too clear what would be required to install from sources.
