Hi, I am new in the world of CentOS and Linux. I am not a computer professional but want to do work in Linux, for which I am trying to learn the Linux basics.

I am having the PC and already installed is Fedora Core 11 as well as Windows XP (dual boot). Fedora has unstability because of its EOL. If I want to install the Cent OS for home PC (personal), should the installation CD (after getting it burned) would prompt me to replace the existing Linux (i.e. Fedora) or would it try to install into the whole of the memory? My requirement is to only replace the existing Fedora Core 11 but to make the Windows remain intact. 2. Though I am new in Linux, and even Fedora commands I don't know much but majority of the commands in Cent OS and Fedora are same? 3. What Cent OS should I download and install? I mean for a single PC at home, can I install the server CentOS or simple CentOS?

My requirement is to only replace the existing Fedora Core 11 but to make the Windows remain intact. It should give the same option that you see in Fedora, remove existing Linux distribution. There is also an option for custom partitioning. The default, if I remember correctly, is to remove existing Linux and replace it. 2. Though I am new in Linux, and even Fedora commands I don't know much but majority of the commands in Cent OS and Fedora are same? Yes. As far as command line goes, aside from package management, (RedHat based distributions, including Fedora and CentOS, use yum, Debian and Ubuntu based distributions use apt, ArchLinux uses pacman, and so on) the rest of the commands are going to be the same. (Or at least extremely similar--sometimes, a distribution has version x of a program and another distribution has version y--and version y might have a few different options.) If you are using the default Gnome desktop, sometimes the layout is slightly different so using the menu may have some slight differences---for example, RedHat and Fedora put the terminal under system tools, whereas Ubuntu (and oddly enough, Oracle Linux) put it under accessories. 3. What Cent OS should I download and install? I mean for a single PC at home, can I install the server CentOS or simple CentOS? There is no server/workstation version. It's all one version and you can customize during installation, which is the same as Fedora. I hope that Cent OS would be good to use at home. The only issues you may run into are that, as the price of stability, there are often older versions of packages--this can sometimes mean that a later version of a program isn't available, because it requires newer glibc versions, and, at times, hardware support from later kernels isn't available. However, due to many 3rd party efforts, such as elrepo, one can find the support for some newer piece of hardware. It sometimes requires more research than would be necessary for one of the more desktop oriented distributions, such as Fedora. -- Scott Robbins PGP keyID EB3467D6 ( 1B48 077D 66F6 9DB0 FDC2 A409 FA54 EB34 67D6 ) gpg --keyserver pgp.mit.edu --recv-keys EB3467D6 Buffy: You know, I just woke up and I looked in the mirror and thought, 'Hey, what's with all the sin.'

I use a fast mirror and d/l overnight with a wget bash script, run by cron. I have downloaded hundreds of DVD iso images with wget and curl during the past years. I had maybe one or two that were corrupted in one way or another, mostly because of improperly configured (windows) webservers. 4Gb with HTTP is no problem nowadays, FTP isn't either. If you have doubts about HTTP/FTP you can always use the Bittorrent way to download (also with commandline tools like btdownloadcurses or similar). It doesn't really matter when you download them although in some cases it can make a difference in speed to download overnight but with most tools you can also specify a maximum bandwith to use. To be sure an image is ok you can always check the image with the md5/sha1 checksum which is normally found in the same directory as the image on the HTTP/FTP server. kind regards, Michel ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] keychain problem
Hello and thanks for your reply! Well I took your advice and removed that keychain scriptlet from .bashrc and put it into .bash_profile. Not sure what the functional difference between the two would be. Perhaps you would care to elaborate? I know that rc stands for resource configuration but other than that I don't know why this statement would be more appropriate in the .bash_profile. However you do seem well versed in this and I hope you don't mind answering this question. So this is what I put into my .bash_profile $(keychain --eval --agents ssh id_rsa) and here is an ssh session from after when I did this: [bluethundr@LCENT01:~]#bash [bluethundr@LCENT01:~]#ssh-agent SSH_AUTH_SOCK=/tmp/ssh-cBwwRR5466/agent.5466; export SSH_AUTH_SOCK; SSH_AGENT_PID=5467; export SSH_AGENT_PID; echo Agent pid 5467; [bluethundr@LCENT01:~]#ssh-add Could not open a connection to your authentication agent.

Thanks for your help. I tried using it in the form of

Hi All, I am wondering what tools are available in CentOS 5.5 that would allow me to measure incoming and outgoing network speeds?

That's a great clarification for which I cannot thank you enough. I will look up SSH Agent Forwarding and start getting the hang of it.

Re: [CentOS] Network bandwidth tools.
It all depends on your requirements: - what sort of questions would you like your solution to be able to answer? (can you give us a few?) - what monitoring infrastructure do you already have? (SNMP, for example, could be rather useful here) - how much level of ad-hoc reporting do you require? - you mentioned incoming and outgoing network speeds, which doesn't necessarily refer to any web-specific analysis; is this what you meant? Plenty of tools out there: ntop may be a good starting point. http://www.cyberciti.biz/faq/howto-install-ntop-on-rhel-centos-fedora-linux/ Netflow and SNMP would be my first points of call if I wanted something more infrastructural. For ad-hoc use of TCP sessions, with a top-like experience, I would just break out tcptrack (there are RPMs available, but doesn't appear to be a Centos package) On 16/01/2011, at 6:08 PM, Jason S-M wrote: Hi All, I am wondering what tools are available in CentOS 5.5 that would allow me to measure incoming and outgoing network speeds?
