  • Help diagnosing Likewise Open Active Directory authentication problem

    - by purpletonic
    I have two servers which were up until recently authenticating against the companies Active Directory Domain controller. I believe a recent change to the Active Directory administrator password caused the servers to stop authenticating against AD. I tried to add the servers back to the domain using the command: domainjoin-cli join example.com adusername this seemed to work without complaints, but when I try to login via ssh with my domain account, I get an invalid password error. When I run the command: lw-enum-users it prints all of the domain users, and looking up my own account, I see that it is valid and my password hasn't expired. I also ran lw-get-status and received the following: LSA Server Status: Agent version: 5.0.0 Uptime: 0 days 3 hours 35 minutes 46 seconds [Authentication provider: lsa-activedirectory-provider] Status: Online Mode: Un-provisioned Domain: example.com Forest: example.com Site: Default-First-Site-Name Online check interval: 300 seconds \[Trusted Domains: 1\] \[Domain: EXAMPLE\] DNS Domain: example.com Netbios name: EXAMPLE Forest name: example.com Trustee DNS name: Client site name: Default-First-Site-Name Domain SID: S-1-5-24-1081533780-4562211299-822531512 Domain GUID: 057f0239-7715-4711-e64b-eb5eeed20e65 Trust Flags: \[0x001d\] \[0x0001 - In forest\] \[0x0004 - Tree root\] \[0x0008 - Primary\] \[0x0010 - Native\] Trust type: Up Level Trust Attributes: \[0x0000\] Trust Direction: Primary Domain Trust Mode: In my forest Trust (MFT) Domain flags: \[0x0001\] \[0x0001 - Primary\] \[Domain Controller (DC) Information\] DC Name: dc1.example.com DC Address: 10.11.0.103 DC Site: Default-First-Site-Name DC Flags: \[0x000003fd\] DC Is PDC: yes DC is time server: yes DC has writeable DS: yes DC is Global Catalog: yes DC is running KDC: yes [Authentication provider: lsa-local-provider] Status: Online Mode: Local system Anyone got any ideas what might be occurring?

  • When using procmail with maildir, it returns error with code I found

    - by bradlis7
    I'm not an expert at procmail, but I have this code: DROPPRIVS=yes DEFAULT=$HOME/Maildir/ :0 * ? /usr/bin/test -d $DEFAULT || /bin/mkdir $DEFAULT { } :0 E { # Bail out if directory could not be created EXITCODE=127 HOST=bail.out } MAILDIR=$HOME/Maildir/ But, when the directory already exists, sometimes it will send a return email with this error: 554 5.3.0 unknown mailer error 127. The email still gets delivered, mind you, but it sends back an error code. I fixed this temporarily by commenting out the EXITCODE and HOST lines, but I'd like to know if there is a better solution. I found this block of code in multiple places across the net, but couldn't really find why this error was coming back to me. It seems to happen when I send an email to a local user, sometimes the user has a .forward file to send it on to other users, sometimes not, but the result has been the same. I also tried removing DROPPRIVS, just in case it was messing up the forwarding, but it did not seem to affect it. Is the line starting with * ? /usr/bin/test a problem? The * signifies a regex, but the ? makes it return an integer value, correct? What is the integer being matched against? Or is it just comparing the integer return value? Thanks for the help.

  • Block all but http traffic on a network interface

    - by Oli
    I've got two network interfaces on an Ubuntu machine which go out to two different networks but both have internet gateways. I need to limit it so that any outgoing http requests it makes (ie through wget) only go through eth0 and all other traffic goes through eth1. I dare say the solution might have something to do with iptables but I've no experience with it so would appreciate all help.

  • [Resolved] Finishing the install of php-xmlrpc on a VPS

    - by wp
    Hi, please help if possible: 1) I was able to completely install php-xmlrpc on a different VPS which uses lxAdmin control panel, without even needing to rebuild php. 2) On a VPS with Direct Admin, I followed detailed instructions (found at the DA site), this included rebuilding php, and after reboot, xml/rpc still doesn't show up in phpinfo.php. Details: centOS 5.3 php5.2.10 php-xmlrpc is installed on the VPS, and the installation "success" was confirmed at the time. Several days later, PHP was rebuilt following detailed instructions (for adding extra modules) provided by direct admin at their site. In the end, xml/rpc still doesn't show up in phpinfo.php. Anyone know how to make this work with Direct Admin? Thank you.

  • Stack , data and address space limits on an Ubuntu server

    - by PaulDaviesC
    I am running an Ubuntu server which has around 5000 users. The users are allowed to SSH in to the system. So in order to cap the memory used up by a process I have capped the address space limits using limits.conf. So my question is , should I be limiting the data and stack ? I feel that is not required since I am capping address space. Are there any pitfalls if I do not cap the stack and data limits?

  • Is bonding mode=5 a solution against MAC flapping?

    - by Yuri
    There is two are interconnected Cisco WS-2950T. By the one GBIC port on first switch connected a first NIC of bonding interface, and by the one GBIC port on second switch connected a second NIC of bonding interface. Of course the both switches sees the bonding MAC-address only on one interface (eg it is GBIC on first switch) and all incoming traffic for bonding interface passes through this GBIC. But in "mode=5" all outgoing traffic are distributed between the all interfaces that make bond. In this case, the packets will be dropped from the second switch and anyway will going through the first switch? Or the division will be working?

  • Help setting up NSD daemon (DNS server)

    - by Catalin
    While searching for a secure dns server I came across the NSD project. I was really impressed by what seemed to me the best option out there that's open source. One problem thought their 'tutorial' is really not beginner friendly. I have basic DNS knoledge but what's in there is out of my league. I need to have multiple sites on this CentOS server I've recently got my hands on. They also need to receive email. Details: I have a master host and would love to set this in the way described in the rows that follow: masterhost.com -> ns1.masterhost.com mail.masterhost.com www.masterhost.com addonhost.com -> ns1.masterhost.com mail.masterhost.com www.addonhost.com And so on. Any help in setting up this DNS server please? All answers and suggestions are welcomed. Thank you in advance.

  • What is the best distro to host a KVM virtualization solution

    - by elventear
    I am looking for a Server oriented distro that we can expect have decent support but also offer as much as possible some of the latest features that KVM might offer. I am leaning towards Ubuntu LTS 10.04, because well it's LTS and more bleeding edge, but I find Ubuntu not serious enough in terms of support (I say this a heavy Ubuntu user). Given that Centos 6 is not out yet, I am not sure if going Centos 5 would be the best option in terms of getting more features from KVM. Any other distro you would recommend that could meet the criteria of long term support? (At least 4 years)

  • Running OLEDB VB6 Windows Progam Under Wine

    - by Beaner
    I'm trying to install a VB6 Windows program that uses OLEDB to access VFP tables to run under Wine 1.0.1 on Ubuntu 9.10. Wine is configured to Windows version Windows XP. The program install ran okay, and I used winetricks to install MDAC 2.8 and JET 4.0 sp7. I also installed Microsoft's vfpoledb and vfpodbc drivers. The application starts and displays an error message, item cannot be found in the collection corresponding to the requested name or ordinal. Does anyone have an idea how to fix this?

  • When using grep from VIM, how to jump to results?

    - by Marplesoft
    When using the grep plugin to VIM, I can search the current directory for all occurrences of a string within a set of files, like this: :grep Ryan *.txt This outputs something like this: file1.txt:3:Ryan was here file2.txt:10:Ryan likes VIM file3.txt:5:superuser.com is a fav of Ryan (1 of 3): Ryan was here Press ENTER or type command to continue If I press enter, it just takes me back to my editor. What I really want to do is be able to open up one of those files and jump to the place where the string was found. Is there a way to do this? The 1 of 3 part makes me think there's a way to tab through the results, but I don't know what commands are available to me. Can anybody shed some light on this?

  • Setting up Pure-FTPd with admin/user permissions for same directory

    - by modulaaron
    I need to set up 2 Pure-FTPd accounts - ftpuser and ftpadmin. Both will have access to a directory that contains 2 subdirectories - upload and downlaod. The permissions criteria needs to be as follows: ftpuser can upload to /upload but cannot view the contents (blind drop). ftpuser can download from /download but cannot write to it. ftpadmin has full read/write permissions to both, including file deletion Currently, the first two are not a problem - disabling /upload read access and /download write access for ftpuser did the job. The problem is that when a file is uploaded by ftpuser, it's permissions are set to 644, meaning that user ftpadmin can only read it (note that all FTP directories are chown'd to ftpuser:ftpadmin). How can I give ftpadmin the power he so rightfully deserves?

  • KVM virtual machine networking, NAT and bridge together

    - by stoqlt
    I have two running KVM guests on an Ubuntu (Lucid) host. One of them uses the simplest NAT method, and DHCP inside. The other uses the bridge method and static IP inside. Both work fine. Can I mix the networking methods? I'd like to create some set of scripts which used the local 192.168.122.x address, no matter if the guest has or not has an additional bridged LAN interface. Having eth0 and eth1 interfaces inside would be fine. Thanks for your interest.

  • monitoring a /21 for potential bad guys with snort and port mirroring

    - by Adeodatus
    Hi all, I want/need to start monitoring our network a bit better. Its an odd network in that it comprises 2 /22 public IPs and a slew of private admin IPs. I do have one point in the network where it all comes together and I can turn on port mirroring on the catalyst. From that port, I'd like to turn up a box running various utilities. Snort is high on my list but it'd be nice to also get some networking statistics with something like Netflow. So, what are peoeple's thoughts. I can turn up a box needed for this with a bit of ease. We have the hardware available. What should I run? I'd love to know what kind of nasty things are potentially going on but I'd also like to see statistics on what people are doing on the network so I can better tweak our systems to handle it better and improve performance. I'm open so please, give me some ideas to go along with what I've got.

  • Running SSL locally on a hosts redirected domain name with Ubuntu and Apache

    - by Matthew Brown
    I recently made some changes to my Ubuntu computer so that a domain name resolved to my local copy of Apache. I edited /etc/hosts and added 127.0.0.1 thisbit.example.com Then set up a VirtualHost for the responses I wishes to create. That all works fine and my testing is now shooting on ahead without harm or risk tot he production server. Now for my next trick I need to test the authentication and so need to do this with HTTPS Basically https://auth.example.com needs to work on my PC without the SSL causing an issue which I imagine would be the case as I am clearly not the true https://auth.example.com but for the basis of this exercise I need to pretend that I am. Now it might be that the Apps I'm testing don't worry about checking the certificate. (Many are in Java which I'm no expert with). What gotchas am I likely to encounter and what is the best way of not letting my own hacks spoil my testing? I'm guessing the place to start is to enable SSL with Apcahe... I've never done that before as it has never come up before.

  • NAT, iptables and problematic ports

    - by Rajie
    I am building a small office network with virtual machines. My schema is this: Computer A: gateway, ip 1.1.1.1, iptables used for NAT [eth0=public internet dhcp, dhcp; eth1=gateway] Computer B: client, ip 1.1.1.2, using gateway from Computer A. NAT is working, and Computer B can access the internet using the A's gateway. I redirected some incoming ports from A to B (for instance, if A receives a request to port 80, it goes automatically to Computer B's Apache). The thing is that I do not really understand how to open/close ports for Computer B from Computer A. I know how to close a port: iptables -A INPUT -p tcp --dport 80 -j DROP And it will refuse all incoming (not output) connections to port 80. However, this works for main interface eth0. I tried to, for instance, drop ingoing and outgoing connections for Computer B, port 80: iptables -A FORWARD -i eth1 -o eth0 -p tcp --dport 80 -j DROP iptables -A FORWARD -i eth0 -o eth1 -p tcp --dport 80 -j DROP But it does not work. And I cannot figure out what I am doing wrong. Any clue?

  • How to fix an SSD

    - by anonymous
    I have a Samsung 128 go SSD : MZ5PA128HMCD-01000. When I'm using it : there is always I/O errors. I tried to secure-erase it. But it is impossible to create a new NTFS (or any filesystem...) partition because I still get I/O errors. I tought maybe upgrading the firmware will solve the problem. Unfortunately, I'm not able to upgrade the firmware with Samsung SSD Magician Tool ... because Magician says there is no Samsung SSD on my computer... Is there a way to make Magician recognize this Samsung MZ5PA128HMCD-01000 SSD? Is another tool available to flash any firmware on a SSD? What should I do to fix this SSD?

  • Problem restarting my Ubuntu system

    - by VoY
    Whenever I try to restart my Ubuntu either from the command line by typing reboot or in GNOME the computer goes from X to console, starts the shutdown process and then a message saying "[ some number ] Starting new kernel" appears on the screen and the computer goes back to X login screen. I suspect this must have something to do with nvidia drivers, because it seemed to have appeared around the time I bought a new graphic card. Also, when I reboot the second time I see weird graphical artifacts on the screen. When I boot from ubuntu live cd I can reboot just fine. I used jaunty, recently I switched to karmic with no change. This bug is very annoying, because I have to hard reset my computer in order to reboot. Also not good for the filesystems, I suspect. Can you suggest a way to debug the cause or if not at least the easiest way to go about reinstalling ubuntu without losing customizations/settings/data?

  • moving dynamic disk from Windows to another Windows computer when original Windows is not available

    - by Andrei
    How do I mount dynamic disk on new system without access to the old OS ? I need to move Dynamic data disk from old Windows XP (Pro, SP3) system, where disk crashed, to new Windows system without having access to the old OS. On new system, Dynamic disk shows as "Dynamic - Foreign". Microfoft has instructions for moving Dynamic Disk [1]. But Microsoft assumes having access to the old system. But I do not have acess to the old system. I am struck with "Dynamic - Foreign" static of the disk on new system. Thanks WinXP Pro SP3 [1] http://technet.microsoft.com/en-us/library/cc779854(WS.10).aspx Move Disk to another computer.

  • "setpci: command not found" in CentOS

    - by spoon16
    I'm trying to configure my Mac Mini running CentOS 5.5 to start automatically when power is restored after a power loss. I understand the following command has to be executed: setpci -s 0:1f.0 0xa4.b=0 When I run that command on my machine though I get bash: setpci: command not found. Is there a package I need to install via yum or something? I'm not seeing a clear answer via Google and I looked at the man page for setpci and it doesn't mention anything. Also, does this command need to be run every time the machine starts or just once?

When i look /etc/sysconfig/network/routes i can see the gateway address. I can not use that file because not every versions of open suse have that file. So i need to use a common way to find out the gateway addres.
