  • Configure ApacheDS 1.5 with accessControlEnabled=true for authenticated access

    - by cmyers
    I need to set up an apacheDS instance. I am using standalone 1.5.5 on Linux. I have removed the example partition and added two of my own, each with their own suffixes. I have imported LDIFs for the two partitions and everything looks correct data-wise. I need to configure ApacheDS to disallow anonymous access. I was able to do that by following some of the directions here: http://directory.apache.org/apacheds/1.5/145-enable-and-disable-anonymous-access.html http://directory.apache.org/apacheds/1.5/32-basic-authorization.html Now only the administrator account (uid=admin,ou=system) can log in and make queries. I need to establish an admin account, and a "regular user" account which can read and write only certain entries within each partition. I tried to read the above docs and I got nuthin'. The second page "basic authorization" is completely incomprehensible to me. When I tried to add a "prescriptiveACI" to it using Apache Directory Studio, I get: Administration point 2.5.4.11=abc,2.5.4.10=efg does not contain an administrativeRole attribute! An administrativeRole attribute in the administrative point is required to add a subordinate subentry. where my partition is "ou=abc,o=def". I have no clue what is going on and the docs are really not helping, I am at a complete loss here. How can it possibly be this hard to just restrict access? P.S. can someone with proper rep please change the tag "apache" to the new tag "ApacheDS"?

  • Help building maya render node spec

    - by Ak
    Hi there, I'm looking to build 4x Maya render slaves/nodes for a friend of mine when his project gets green lit. The project involves MentalRay and lots of glass. I'm unsure if the new i7's 9xx or 8xx with hyper threading will do any better than a core 2 quad of the same (or close enough) speed. Does hyper threading make a difference to Maya or is it more performance per core based? I'm sure he's prefer I'd build another render node than pay for a bleeding edge CPU that only adds fractionly more GHz. -- The rest of the spec so far: 4Gb - 8Gb ram 64 bit OS: Probably Windows 7 (I know Linux is free, but want to build something my friend can support himself as easily as he supports his own workstation) 1TB HDD to hold textures, Maya files and renders which will be copied to central storage later Mobo with on-board video, gigabit NIC 500 - 650 watt PSU Desktop case something like a: Cooler Master ATCS 840 The machines will sold afterwards if necessary. -- If anyone has had experience in Maya and has done any tests with the new CPUs vs. the older ones I'd really appreciate your input.

  • Snort/Barnyard2 Logging

    - by Eric
    I need some help with my Snort/Barnyard2 setup. My goal is to have Snort send unified2 logs to Barnyard2 and then have Barnyard2 send the data to other locations. Here is my currrent setup. OS Scientific Linux 6 Snort Version 2.9.2.3 Barnyard2 Version 2.1.9 Snort command snort -c /etc/snort/snort.conf -i eth2 & Barnyard2 command /usr/local/bin/barnyard2 -c /etc/snort/barnyard2.conf -d /var/log/snort -f snort.log -w /var/log/snort/barnyard.waldo & snort.conf output unified2: filename snort.log, limit 128 barnyard2.conf output alert_syslog: host=127.0.0.1 output database: log, mysql, user=snort dbname=snort password=password host=localhost With this setup, barnyard2 is showing all of the correct information in the database and I'm using BASE to view it on the web GUI. I was hoping to be able to send the full packet data to syslog with barnyard2 but after reading around, it seems that it is impossible to do that. So I then started trying to modify the snort.conf file and add lines like "output alert_full: alert.full". This definitely gave me a lot more information but still not the full packet data like I want. So my question is, is there anyway I can use barnyard2 to send the full packet data of alerts to a human readable file? Since I can't send it directly to syslog, I can create another process to take the data from that file and ship it off to another server. If not, what flags and/or snort.conf configuration would you recommend to get the most data possible but still be able to handle quite a bit of traffic? In the end of it all, these alerts will be shipped to a central server via a SSH tunnel. I'm trying to stay away from databases.

  • What's the risk of running a Domain Controller so that it is accessible from the internet?

    - by Adrian Grigore
    I have three remote dedicated web servers at different webhosts. Adding them to a common domain would make a lot of administration tasks much easier. Since two of the servers are running Windows 2008 R2 Standard, I thought about promoting them to Domain Controllers in order to set up the windows domain. There's another thread at Serverfault that recommends this. At the same time I've read a lot of times on different websites that this is not a good idea because an domain controller should always be behind a firewall LAN. But I can't set up something like this because I don't have a LAN with a static IP accessible from the internet. In fact I don't even have a windows server in my LAN. What I have not found out is why exposing a DC to the Internet would be bad idea. The only risk I can see is that if someone penetrates one of my webservers, it should be much easier to penetrate the others as well. But as far as I can see that's the worst case scenario since I am only going my web servers to that domain, not any computers from my local network. Is this the only downside or does it also make it easier to penetrate one of my web servers in the first place? Thanks, Adrian

  • Why did MAC-Adress Cloning Fix My Router?

    - by FranticPedantic
    I have a Belkin router, and about a year ago, I suddenly lost my internet connectivity from Comcast. The internet worked fine when I plugged it right into my laptop, so I just ignored it. When I moved to another apartmnet I eventually took the dive and called tech support. The tech told me to clone my MAC address which completely fixed the issue. Now I know what a MAC address is and I've read what MAC cloning is. What has bothered me since is that I don't see how this fixed the issue. As I have understood MAC address cloning, it has the router pretend it has the same MAC address as my computer. Here is why I don't understand why this fixes my issue: I have used several different computers with this router. Cloning the MAC address fixed it for ALL of my computers. The laptop I first used with my ISP was not the one that I eventually had connected when I cloned the address. Furthermore, I didn't have any problems for quite some time after I stopped using the first computer. It wasn't like the internet suddenly stopped working when I changed which laptop I was using Now it occurred to me that maybe there was some sort of expiration? Except... Which MAC address did it clone? It was just an option in the router administration page. Did it just pick whichever computer was connected to it? If my ISP still wanted the MAC of my first computer, how did some other computer's fix it? As mentioned earlier, why did this problem seemingly stem from nowhere? Anyway, I don't have any current problems so this is more just out of general curiosity. If anybody can explain it, it would be appreciated!

  • Looking for cheap Wireless router, with USB for attached USB disk drive

    - by geoffc
    I have a 802.11b router at home (DLink DI-614+ (B rev)) and it is working perfectly well for me. I want to replace it though, since it is out of updates, and now several years old and heck, I want a new toy to configure! I was trying to decide what to get. I could care less about 802.11g or n support, since B is fast enough, but every device in my house is now B/G, so G would be fine for me. N buys me little to nothing. (Small enough house that range is a non-issue). The features I realized I want are a USB port for sharing a USB hard drive. I would like to have a central device I could store files on. I do not want to waste the power of an always running PC to do this, so a router seems like the place to go. I would love it, if it could support Vonage VOIP as well, then I could ditch a power brick from a second device (I have the small DLink Vonage VOIP box). All the current examples of this router (with USB drive, yet to find one with VOIP too!) are in the $100+ range, and N and silly, when a B/G is in the $30 range around here.

  • How do you add a domain name to a VPS?

    - by jasonaburton
    Hi all, I have a VPS with allgamer.net (I use it to play minecraft). I also have a domain name with networksolutions.com What I want to do is attach that domain name to the VPS. I want to run a wiki on my domain name. If this is possible I can avoid buying another hosting plan just for the wiki. How do I go about doing this? I have very little knowledge in server administration so any advice you guys have is greatly appreciated! I'm pretty sure I have to change the DNS in my domain name to the DNS for my VPS, but on allgamer.net's interface there is no discernable place to find out what I need to change it to. Is there a way to find out the DNS via SSH on my VPS? As well, when I first got my VPS with allgamer.net I filled out a form for it with all my information, but they also wanted a domain name along with it. I gave them the domain name I currently own, but for some reason, it's like it's not connected to the VPS, like if I go to mydomain.com there's nothing, as well, if I use mydomain.com for my minecraft server, it also doesn't work. It's as if it's serving no purpose by being "attached" to my VPS. Any insights into this? Thanks for any help you guys can give me.

  • Disabling CPU management

  • remote telnet and email

    - by Mustafa Ismail Mustafa
    This issue has been occupying my work for the last few days and I will be understating when I say its driven me up the blasted walls. Essentially, I can ping and tracert the domain jnrcs.org and the subdomains mail.jnrcs.org and mail.jordanredcrescent.org. All three mentioned point to ip address 212.38.147.97. About 4 days ago, when we registered the domain "jnrcs.org" suddenly all external connection to the mail server from outside was lost. Not just mail, but other http based port-forwarded or natted services (such as camera surveillance and pbx services). I tried good old telnet (I'm a linux user) and I get the following output: telnet> o mail.jnrcs.org 25 Trying 212.38.147.97... telnet: Unable to connect to remote host: No route to host telnet> Tracert gives me: traceroute to mail.jnrcs.org (212.38.147.97), 30 hops max, 60 byte packets 1 192.168.1.2 (192.168.1.2) 0.869 ms 0.944 ms * 2 * * * 3 * * * 4 * * * 5 * * * 6 * 212.38.128.118 (212.38.128.118) 33.875 ms 39.187 ms 7 * * * 8 * * * 9 * * * 10 * * * 11 * * 212.38.147.97 (212.38.147.97) 67.621 ms I am stumped. Other friends from all around the world can telnet no problem. What could have possibly happened to make telnet/smtp/pop/imap/http access stop? Please bear in mind I'm primarily a developer but I [am under the delusion] that I can carry my weight in IT administration :) TIA

  • What's the right way to create a Ubuntu user whose home directory is /var/www/SITE?

    - by Leonnears
    First of, I need to state I'm a complete ignorant when it comes to server administration on Ubuntu, and I'm doing what I can. I have been trying to do this for hours with no luck. Basically, I want to create a Ubuntu user whose home directory is /var/www/SITE, and prefered it is chroot'd to it. The chroot part is not so important right now, as first I prefer to make anything work. The user should be able to upload files here and the webserver (www-data user?) should be able to pick them up with no problem. I was able to create the user and give it the home directory /var/www/SITE. (the user is "anders"). I gave him a password, and "anders" can connect to FTP just fine and upload files. But here's where things don't work: While my user can upload files to that /var/www/SITE directory, when I access the webpage on my browser I get a Forbidden error. Note that anders is also a member of the www-data group. I can fix this by running sudo chmod g+s /var/www/SITE/* anders -R but this is of course not ideal. Ideally the files should "work" as soon as I upload them. What's the right way to fix this? If it matters (don't think so), I'm editing my files in Coda 2 and anders is the user for it.

  • How to collect the performance data of a server during an unreachable/down period using Nagios?

    - by gsc-frank
    Some time services and host stop responding due to a poor server performance. I mean, if for some reason (could be lot of concurrency services access, a expensive backup execution on the server or whatever that consume tons of server resources) a server performance is very degraded, that could lead that the server isn't capable to establish any "normal network communication" (without trigger whatever standards timeouts defined for such communication). Knowing host's performance data (cpu, memory, ...) in case of available during that period (host is not down and despite of its performance degradation still allow plugins collect performance data) could be very useful for sysadmin to try to determine what cause the problem, or at least, if the host performance was good and don't interfered at all in the host/service down. This problem could be solved using remote active (NRPE) or remote passive (NSCA) if such remote solutions could store (buffered) perf data to be send to central Nagios server when host performance or network outage allow it. I read the doc of both solutions and can't find any reference to such buffer mechanism neither what happened in case that NSCA can't reach Nagios server. Any idea of how solve this lack of info? so useful for forensic analysis. EDIT: My questions isn about which tools I can use to debug perf problems or gather perf data to analysis, but is about how collect (using Nagios) host perf data even during a network outage for its posterior analysis (kind of forensic analysis). The idea is integrate such data to Nagios graphers like pnp4nagios and NagiosGrapther. I know that I could install tools like Cacti in each of my host, and have a kind of performance data collection redundancy, but I really want avoid that and try to solve all perf analysis requirements with one tools: Nagios

  • Black screen appears when booting new install of Ubuntu 11.10 on my desktop, cannot access Grub menu to fix

    - by izn
    I installed 11.10 on my desktop PC but get a black screen after the BIOS screen when I try to boot it. I was able to run 10.04.04 on my hard drive before installing 11.10 and I am also able to use 11.10 on my usb pendrive and CD ROM. I've tried unplugging all USB devices before booting and also upgrading from 11.10 to 11.10. Holding the shift key from the BIOS screen doesn't allow me to access the GRUB menu to try: Highlight the first entry, press “e” to edit it. Navigate to words “quiet splash”, delete them and type “nomodeset” in their place (without quotes). Press Ctrl + X to continue boot. Once on the desktop, go to System Administration Additional Drivers and activate the recommended drivers. So running 11.10 on my pendrive, I tried editing /etc/default/grub, commenting out the GRUB_HIDDEN_TIMEOUT setting by putting a '#' in front of it to display the grub menu and setting GRUB_TIMEOUT setting to a value greater than or equal to 1 e.g. GRUB_TIMEOUT=10. However, when I run sudo update-grub, I get: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?) I get the same error with update-grub after: sudo mount /dev/sda1 /mnt and after: sudo grub-install --root-directory=/mnt /dev/sda reboot sudo update-grub Other suggestions to fix the update-grub problem: Open synaptic, then purge all the related grub installed packages and reinstall grub-pc then and finally: sudo update-grub Or use Grub Customizer http://ubuntuforums.org/showthread.php?t=1195275 What would be the best way to approach this? I'm concerned about purging "all the related grub installed packages" but if it's true some files are corrupted this would seem necessary. Also, was I executing the correct commands i.e. with mount and grub-install, before running grub-update?

  • Alternatives to Splunk?

    - by MichaelGG
    I'm pretty impressed with Splunk, especially version 4. Pretty graphs, alerting (Enterprise only), and fast, accurate, searching. It's a great product. However, the cost just way too high to consider for full production use for our company. All we really need is to be able to index different logs in a central place, and have reasonable searching on that. Having alerts based on a saved search is also really nice. We don't really go beyond that. In fact, our biggest usage has been in deploying new applications. Everything gets logged via log4net to either the Event log on Windows or a text file on Linux. Splunk makes it pretty easy to quickly search across those to make sure all the parts of the app are working ok -- that's saved us tons of time versus hunting down individual logging sources. What alternatives exist in this market? I have a sinking feeling Splunk's pricing is so high because they have the best product by far, and they know it. We want the server to run on Windows. I'd be open to a split model, using one product for general logs (collect via syslog/Snare), and a dedicated product for our custom apps (like Log4Net Dashboard). Would using a simple syslog server such as Kiwi, sent to SQL Server (perhaps with fulltext enabled) work? I'd hope the cost should be well under 5 figures, USD. (And yes, I know, we're cheap. We're a startup with little money, and BizSpark takes care of all our MS licensing.) Edit: I should add, we have about 10 physical servers, 20 VMs, and a couple firewalls and switches. 90% is Windows.

  • VMware virtual machine network devices malfunctioning

    - by sheepz
    I'm running Ubuntu 10.04 LTS and VMvware workstation 7.0.1 build-227600. The virtual machine i'm running in VMware is a custom distribution built on Debian Linux version 3.1. I'm still pretty much a beginner with UNIX administration. After having messed around with the vmware (changed only the name of the folder, the vmx and and other .v* files accordingly in which the .vmx was situated, and the configuration in the vmx file accordingly), the network devices on the virtual machine do not work anymore. The virtual machine is used for securely sending messages. The virtual machine: As far as I know, this perl file called proxy-gen-ifalias eth0 is responsible for properly setting up the two virtual network devices eth0 and eth1. The Virtual machine comes with a GUI interface in which I have set up two ethernet network devices, one internal, the other external. Now, after having messed around with this, the UI gives me this error message: perl proxy-gen-ifalias eth0 /etc/modprobe.d/alias-eth0 /sbin/update-modules perl proxy-gen-ifalias eth1 /etc/modprobe.d/alias-eth1 /sbin/update-modules ifdown eth0 ifdown: interface eth0 not configured ifdown eth1 ifdown: interface eth1 not configured perl proxy-gen-netcfg /etc/network/interfaces ifup eth0 SICCSIFADDR: No such device eth0: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device eth0: ERROR while getting interface flags: No such device Failed to bring up eth0. ifconfig eth0 eth0: error fetching interface information: Device not found make: *** [/etc/network/interfaces] Error 1 ~ Here are the contents of the two perl files referred to in the message: paste.pocoo.org/show/2AMzAYhoCRZqlGY7wUFk/ proxy-gen-netcfg

  • Extract large zip file (50 GB) on Mac OS X

    - by chingjun
    I was trying to move the files to another hard drive. So I archived all my photos in one large ZIP file using the Mac OS X built-in compress function. But the file failed to extract. I've tried many programs, but none of the programs I tried were able to extract the file. I've tried Mac OS X's extract utility, StuffIt Expander, 7-Zip (command line), all failed. Mac's archive utility and StuffIt don't seem to support large files, and 7-Zip's command line version gave an error stating unsupported archive. I have no luck in Windows either as many of my files have Chinese filenames, and couldn't extract to the correct name under Windows. Are there some programs that can support large files, can handle files compressed using Mac OS X's compress function, and can support UTF-8 filename? With or without GUI is fine. Update Well, I had made the wrong decision to compress the files, and it's already too late. I thought I should be able to extract the file if I could compress it. It's too late, the original copies are gone, only a large ZIP file left here. I have tried using 'unzip', but it says End-of-central-directory signature not found. I guess it doesn't have large file support as well. I would try the Windows Vista method as stated by SuperMagic, but I need to borrow a computer for that. Anyway, thank you everyone, but please provide more suggestions on what software that could possibly extract that file.

  • ProCurve network expansion

    - by Blue Warrior NFB
    I've hit a bit of a wall with our network scale-out. As it stands right now: We have five ProCurve 2910al switches connected as above, but with 10GbE connections (two CX4, two fiber). This fully populates the central switch above, there will be no more 10GbE Ethernet connections from that device. This group of switches is not stacked (no stack directive). Sometime in the next two or three months I'll need to add a sixth, and I'm not sure how deep of a hole I'm in. Ideally I'd replace the core switch with something more capable and has more 10GbE ports. However, that's a major outage and that requires special scheduling. The two edge switches connected via fiber have dual-port 10GbE cards in them, so I could physically put another switch on the far end of one of those. I don't know how much of a good or bad idea that would be though. Is that too many segments between end-points?

  • Centralized Windows/Mac Patch Management that is easy to use

    - by BiggsTRC
    I'm looking for advice on what patch management solutions you would recommend based upon your experience. I'm also looking for which ones you would not recommend based upon your experience. We have a mixed network of Windows and Mac clients. Our central servers are all Windows servers, although I have considered putting in a Mac server to better handle our Mac clients. The issue we are facing currently is that we need to maintain the patches on all of our third-party applications. Right now we use WSUS, which handles with patching of Windows and some Microsoft products but that is about it. I need something to cover the other applications, specifically things like Adobe products (Reader, Flash, Dreamweaver, etc.) Our network isn't that big (maybe 200 clients) and I don't have a person to dedicate just to patching and maintaining a patch management solution. Thus very large and complicated solutions like System Center are most likely out. I have recently been looking at Dell's Kace K1000 solution (http://www.kace.com/products/systems-management-appliance/). It seems simple and it provides a lot of tools in one package that I would like/need as well. I like the fact that it is self-contained in an appliance and that it is designed for solutions like mine. However, I'm not sure if this is the best solution. I've also looked some at Shavlik's Netchk solution (http://www.shavlik.com/netchk-protect.aspx) but I don't need an anti-virus product. However, it looks like they might have a very good patch database. My question is this: What are your thoughts on these to products? Are there better products out there? Are there issues that I'm not considering? I want something that is very good at patching a broad range of products, that is simple to use, that takes a minimal amount of management (like WSUS), and that (hopefully) works with Mac and Windows.

  • Gentoo Linux useful utilities

    - by Alakdae
    I want to make a list of utilities that come in handy in Gentoo (general Linux tools available in all distributions also appreciated). What tools and commands do you use and consider helpful in administration of a Gentoo server? I will update the list with command from answers from time to time. eclean Utility for cleaning distfiles and binary packages. Usage example: eclean distfiles Usage example output: Cleans out the files in /usr/portage/distfiles. Pretty handy.

  • how does svn work with apache?

    - by ajsie
    i've got ubuntu installed with lamp. im using webdav to upload/download files to/from the ubuntu web server, after i have edited the php source files in netbeans. however, i wonder what is best practice for editing source files and committing these changes to the new website. cause if we are 2-3 developers, i guess we have to use svn. but i have never used it before so i wonder how it works. should i install it and then select the /var/www (apaches webroot) as the repository folder? then when i check in, all the changes will apply immediately? could someone please explain following steps: how to download, edit the source files, upload the files and see the new changes in the website. cause i have only worked with a local apache before, and it was only me. now there will be some more programmers so i have to set up a decent, central environment for this, and have to know how netbeans, svn, webdav and apache works all together. thanks!

  • How can I download a file directly to a web server?

    - by matt
    I'd like to download files directly to a hosted server, whether it's one I set up myself or a hosted service like Dropbox. For example, when I download a podcast, instead of downloading it to my computer then uploading it to the server, how can I have it download directly to the cloud. My interest here is reducing the traffic I'm using over a metered data plan on my laptop, so I don't want my computer acting as a physical intermediary caching the file. Ideally, there would be some way for me to have a download link and tell it to go directly to my server. How can I accomplish this? I realize that this question is potentially involving a "webapp" and it is potentially involving "server administration" and since my goal is to cut my computer out of the loop I can see people saying this is off-topic and should be on another site. My issue is this: I don't know if this is going to be a webapp solution or a server solution but I do know regardless I'm going to be using a computer to get it done and I am replacing a function that's currently done on my computer so I figured I'd ask it here. If I was wrong and this definitely should be at webapps feel free to let me know or just migrate it.

  • Multiple cable adapter setup not working - VGA to smartphone. All cables tested and work

    - by Christopher Rucinski
    Issue Pictured overhead projector setup does not work. #1 - #2 - #3 - Phone. All cables are tested and work! The issue is the HDMI connection between cable #2 and #3. With all other cables, the screen will automatically be displayed onto the projector screen. No extra work needed. With the pictured setup, the smartphone screen is not displayed onto the projector screen. What is the issue with the HDMI connection?? Background We recently had to do presentations at work (school), but the administration only provided VGA means of hooking up to it. Mostly likely reason probably dealt with cost. Anyways, there are several teachers that have brand new Samsung Series 9 ultrabooks (or similar). You know, the ones without VGA support. So I bought an adapter for those ultrabooks. Cable #5 in the picture below. However, both my coworker and I have been wanting to just display our phone screens on the projector. This I knew would require some extra work. What I have VGA cable to projector (cables go through the wall) For laptops HDMI to VGA cable For laptops MHL adapter For 11-pin microUSB phones microHDMI to VGA cable For ultrabooks 11-pin to 5-pin microUSB adapter For older 5-pin microUSB phones) Equipment Projectors 1 projector with VGA and HDMI input (issue is coworkers forget to switch sources) 1 projector with VGA only input Laptops 2 new Samsung ultrabooks w/o VGA or HDMI support 1 ultrabook with VGA and HDMI support several other laptops with at least VGA support 1 tablet with 11-pin microUSB at least 1 new phone with 11-pin microUSB at least 1 old phone with 5-pin microUSB Tested VGA cable (#1) to laptop Good VGA cable (#1) to HDMI adapter (#2) to laptop Good VGA cable (#1) to microHDMI adapter (#5) to laptop Good Projector to HDMI cable (not shown) to MHL adapter (#3) to Galaxy Note 3 smartphone Good VGA cable (#1) to HDMI adapter (#2) to MHL adapter (#3) to Galaxy Note 3 smartphone Does not work!! Extra Notes The 11-pin MHL adapter will not fit inside the 11-pin to 5-pin microUSB adapter so older phones can be displayed on the screen.

  • How do I install the main repositories for RHEL6

    - by eisaacson
    We've setup RHEL6 on a new server. As far as we can tell, our subscription is all setup properly. However, when I run yum repolist, it doesn't show any repositories. /etc/yum.repos.d/redhat.repo is empty. I tried pasting in the content from another RHEL6 server's redhat.repo but as soon as I run yum, it wipes it out again. I just need to get the basic RedHat repositories setup so I can install packages. EDIT: Using the GUI, I went to System Administration Red Hat Subscription Manager. Under the 'Products' tab, it did not show any products. EDIT: When I run yum update, here's what I get: # yum update Loaded plugins: product-id, refresh-packagekit, security, subscription-manager This system is receiving updates from Red Hat Subscription Management. Setting up Update Process No Packages marked for Update When I log in to RedHat customer portal, it shows that subscription as active. EDIT: To make sure I wasn't having a subscription issue. I re-registered and re-subscribed. I get all the same results. # subscription-manager register --force # subscription-manager subscribe --pool=*redacted* EDIT: contents of /etc/yum.conf [main] cachedir=/var/cache/yum/$basearch/$releasever keepcache=0 debuglevel=2 logfile=/var/log/yum.log exactarch=1 obsoletes=1 gpgcheck=1 plugins=1 installonly_limit=3 contents of /etc/yum/pluginconf.d/rhnplugin.conf: [main] enabled = 0 gpgcheck = 1

  • Symantec Endpoint Protection Virus Definitions

    - by Gus Denton
    I have done some Googling but I cannot get a definitive answer certainly not from the Symantec KB. I have a Virtualised Win 2003R2 server 32bit. It has been provisioned to me with Symantec Endpoint Protection 11.0.62xxx CLIENT (not a definitions server) the directory C:\Program Files\Common Files\Symantec Shared\VirusDefs is 750MB IT doesn't contain .tmp directories so it is NOT a corrupt definitions server. IT does contain directories named with a date pattern YYYYMMDD.xxx Some of these folders are 12 months old and I would like to recover the space. The sysmantect forums are full of this stuff but a lot of the postings contain links back to documents that are not specific to End Point Protection Client. It appears that I should be able to delete the older folders and all will be OK. with a service restart however there is a warning about having Live Update Administrator Installed Firstly I have no idea if I have this installed how to I check and secondly can I just ditch these old files and restart ? Regards Gus Denton Learning and Teaching Uni of New South Wales Sydney Australia For those trying to assist me I thankyou. I have followed some instructions found on the Symantec site and assumed that the response from Nixphoe would resolve my issue. It appears that as I am on a provisioned VM from a central IT unit I cannot run the Symantec commands from the Run prompt as my admin creds to get me in. (smc -stop) Basically I need to claw back some Diskspace from the c: drive which is being filed up with WSUS patches and Symantec files. I have managed to delete one symantec cache through the live update control panel and recovered 470Mb I suppose my last question for those more experienced than myself is, can I simply remove say the two oldest virus definition folders without completely foobaring the End Point protection and the server ? Regards Gus
