  • Httpd and LDAP Authentication not working for sub-pages

    - by DavisTasar
    I just recently installed a Nagios implementation, and I'm trying to get LDAP authentication working for httpd on Red Hat. (nagios.conf for Apache config below, sanitized of course) ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin" <Directory "/usr/local/nagios/sbin"> #SSLRequireSSL Options ExecCGI AllowOverride none AuthType Basic AuthName "LDAP Authentication" AuthLDAPURL "ldap://my.domain.controller:389/OU=Users,DC=my,DC=domain,DC=controller?sAMAccountName?sub?(objectClass=user)" NONE AuthzLDAPAuthoritative off AuthLDAPBindDN "CN=NagiosAdmin,DC=my,DC=domain,DC=controller" AuthLDAPBindPassword "myPassword" require valid-user </Directory> Alias /nagios "/usr/local/nagios/share" <Directory /usr/local/nagios/share> #SSLRequireSSL Options None AllowOverride none AuthBasicProvider ldap AuthType Basic AuthName "LDAP Authentication" AuthzLDAPAuthoritative off AuthLDAPURL "ldap://my.domain.controller:389/OU=Users,DC=my,DC=domain,DC=controller?sAMAccountName?sub?(objectClass=user)" NONE AuthLDAPBindDN "CN=NagiosAdmin,DC=my,DC=domain,DC=controller" AuthLDAPBindPassword "myPassword" require valid-user </Directory> Now, the initial authentication works, so when you first hit the page you can log in just fine. However, when you go anywhere else, it prompts you for authentication, fails (asking for a re-prompt), and gives this error message: [Mon Oct 21 14:46:23 2013] [error] [client 172.28.9.30] access to /nagios/cgi-bin/statusmap.cgi failed, reason: verification of user id '<myuseraccount>' not configured, referer: http://<nagiosserver>/nagios/side.php I'm almost certain its a simple flag or option, but I just can't find it, and I don't have a lot of experience working with Apache. Any assistance or help would be greatly appreciated.

  • Log incoming requests on Ubuntu (ports 80, 443)

    - by Maxim Eliseev
    We have Tomcat running on Ubuntu server. It runs a web service, open to the internet. Sometimes it has a sudden spike of traffic and goes down. There is nothing unusual in Tomcat access logs. I guess it is because some of the requests are so 'heavy' that they never finish and hence are not recorded to Tomcat access logs. Is there a way to configure Ubuntu to log incoming requests in the following format (below)? Date, Time, URL (with query string params), IP address (of client) There should be one line per request. Each request should be logged before it is executed. Only incoming requests to ports 80 and 443 should be logged.

  • VMware - Broadcom 1000Gbps NIC does not link at 100Mbps to a Cisco switch port

    - by Spirit
    Today we've stumbled on a very awkward situation with our VMWare Server. The server is with ESX 3.5 that has a 1Gbps NIC. We bought a brand new managed Cisco Linksys switch with 10/100Mbps interface ports but when we plugged the cable in one of the ports the link simply does not wanted to activate :S... Does anyone with more VMware experience have ever had similar problem? From what I know is that 1Gbps NICs are backwards compatible with 100Mbps switches. This is what we've tryed so far but with no success: Tryed: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004089 Tryed to modify the /etc/modules.conf folowing the guide from this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=813 After the changes I have restarted the networking services using # service network restart, # service mgmt-vmware restart and # service vmware-vpxa restart It seems that no matter how many times, or whatever approach/method (GUI or Shell) we try to change the speed and duplex of the network adapter and to force it to 100mbps it only accepts 1Gbps .. I am starting to go nuts :@

  • How to configure sendmail to relay through a specific server

    - by ErebusBat
    I have a tiny home server setup behind my cable modem (bresnan communications). I want to be able for this box to send out email (not receive) for notifications and whatnot. What I have already done: I have installed and configured sendmail. I have added mail.bresnan.net as my SMART_HOST directive. What I belive the problem is When I attempt to send an email I get the following in my mail log: Dec 22 10:24:17 batcave sendmail[1530]: oBMHOHrs001530: from=aburns, size=140, class=0, nrcpts=1, msgid=<[email protected]>, relay=aburns@localhost Dec 22 10:24:17 batcave sm-mta[1531]: oBMHOHWZ001531: from=<[email protected]>, size=397, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Dec 22 10:24:17 batcave sendmail[1530]: oBMHOHrs001530: to=<[email protected]>, ctladdr=aburns (1000/1000), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30140, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (oBMHOHWZ001531 Message accepted for delivery) Dec 22 10:24:18 batcave sm-mta[1517]: oBMH9mVv001357: to=<[email protected]>, ctladdr=<[email protected]> (1000/1000), delay=00:14:30, xdelay=00:00:42, mailer=relay, pri=300339, relay=pmx0.bresnan.net. [69.145.248.1], dsn=4.0.0, stat=Deferred: Connection timed out with pmx0.bresnan.net. You can see where the message is accepted for delivery by my sendmail server, then where it attempts to hand off to bresnan's server and it timesout. This is where my question is. Asstute readers will notice that pmx0.bresnan.net is not what I have my SMART_HOST directive set as. This is the (outside?) MX server for the bresnan.com/net domain. Apparently bresnan has their network configured so that you can not access this server from within their own network and instead must use the mail.bresnan.net server (which I can connect to). The problem is that I don't know how to tell sendmail to use this server and not the domain. What I have tried Setting a hosts entry so that the pmx0 server points to the mail IP address. This doesn't work, which makes sense as sendmail is obviously doing an MX query to find the server which returns the IP so there is never a need to do a 'normal' DNS resolve so the hosts file never gets involved.

  • Log with iptalbes which user is delivering email to port 25

    - by Maus
    Because we got blacklisted on CBL I set up the following firewall rules with iptables: #!/bin/bash iptables -A OUTPUT -d 127.0.0.1 -p tcp -m tcp --dport 25 -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --gid-owner mail -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --uid-owner root -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --uid-owner Debian-exim -j ACCEPT iptables -A OUTPUT -p tcp -m limit --limit 15/minute -m tcp --dport 25 -j LOG --log-prefix "LOCAL_DROPPED_SPAM" iptables -A OUTPUT -p tcp -m tcp --dport 25 -j REJECT --reject-with icmp-port-unreachable I'm not able to connect to port 25 from localhost with another user than root or a mail group member - So it seems to work. Still some questions remain: How effective do you rate this rule-set to prevent spam coming from bad PHP-Scripts hosted on the server? Is there a way to block port 25 and 587 within the same statement? Is the usage of /usr/sbin/sendmail also limited or blocked by this rule-set? Is there a way to log the username of all other attempts which try to deliver stuff to port 25?

  • moving files and directories between two machine, via a third, preserving permissions and usernames

    - by Jarmund
    The situation is as follows: Machine A has a file repository accessible via rsync Machine B needs the above mentioned files with all permissions and ownerships intact (including groups etc) Machine C has access to both A and B, but has a completely different set of users. Normally, i would just rsync everything over, directly between A and B, but due to severely limited bandwidth at the moment, i need something different, as rsync times out after building the list of the 430 files (49Mb uncompressed... can be compressed down to ~7Mb). What i've tried so far: rsync everything over from A to C, tar it, copy the tarball over, and then untar it, however, this messes up the ownership and/or the permissions. To rsync it from A to C, i run this command: rsync --numeric-ids --password-file=/root/rsync_pwd_file -oaPvu rsync://[email protected]/portal_2/ ./portal_2/ ...and from the looks of things, they do end up on C with the correct ownerships/permissions/flags/everything (not 100% sure, though.. are there any more switches i can throw in there? did i miss something?) copying the tarball over is simple enough (slow as a one-legged turtle due to the bandwidth, but it checksums out alright) What i'm unsure of is the flags and switches for creating and extracting the tarball, so could someone please provide the full commands for creating a tarball from /root/portal_2 on machine C (with everything intact) and extracting the tarball into /var/ex/portal_2 on machine B? ? Also, are there any other approaches worth mentioning that could allow me to perform this? I have root access to A and C, whereas i only have rsync access to B. PS: I'm running rsync v2.6.9 on machine B, and unfortunately i do not have the oportunity to upgrade to v3

  • When using gt5 in my home directory I get a blank page.

    - by MT
    When using gt5 in various directories on my system (including my home directory) I get blank results. If I limit the max-depth enough, I get results. For example, in my home directory 'gt5 --max-depth 2' produces a listing, while 'gt5 --max-depth 3' produces a blank page. I've noticed that the temporary html file that gets created in tmp (such as '/tmp/gt5.9035.kJVM08Y9/gt5.html' is a zero-byte file. I can successfully do a du in the same directory (which is what I thought gt5 was using), so I'm not sure what to check?

  • Software RAID 1 broken, how do I fix this?

    - by Edward
    I'm running CentOS 6 x86_64. There is a software RAID 1 being used on the two internal 80GB drives. I got the following e-mail sent to me: A DegradedArray event had been detected on md device /dev/md1. Faithfully yours, etc. P.S. The /proc/mdstat file currently contains the following: Personalities : [raid1] md0 : active raid1 sda1[0] 511988 blocks super 1.0 [2/1] [U_] md1 : active raid1 sda2[0] 8190968 blocks super 1.1 [2/1] [U_] bitmap: 1/1 pages [4KB], 65536KB chunk md4 : active raid1 sdc1[0] sdb1[1] 1953512400 blocks super 1.2 [2/2] [UU] md3 : active raid1 sdd5[1] sda5[0] 61224892 blocks super 1.1 [2/2] [UU] bitmap: 1/1 pages [4KB], 65536KB chunk md2 : active raid1 sdd3[1] sda3[0] 8190968 blocks super 1.1 [2/2] [UU] unused devices: <none> The system appears to have booted fine and is working. The two drives' content did not change at all. I only removed and reinstalled them while I was booted on the CentOS Live DVD. How do I get the array working again?

  • Cygwin file and directory user and group

    - by dvanaria
    I use Cygwin as my main development environment on both my home and work computers. In order to share files between the two computers, I use Dropbox, which is installed in the following folder on both computers: c:\cygwin\home\dvanaria\dropbox Everything works great, except for one thing. When I'm working on my home computer and do an ls -l on any directory, all the files show up as owned by dvanaria of group Users. But when I work from my work computer, an ls -l shows all files as being owned by Administrators and of group Domain Users. I know Cygwin uses some kind of mapping between Windows users and permissions to the /etc/passwd file. But to be honest I have no idea how this file works or how it maps to Windows under Cygwin. Could anyone help figure this out? The main problem is that I can't edit any files when using my work computer, only read them.

  • VirtualBox error with Ubuntu virtual machine

    - by user2985363
    I am trying to work on a coding project and cannot open my Ubuntu virtual machine with Oracle VM VirtualBox. I took a snapshot yesterday at about 11, and it was working fine. Several times I closed and reopened it. Today when I tried to open it, I kept getting the error below. Failed to open a session for the virtual machine Ubuntu 12.04 32-bit. VM cannot start because the saved state file 'C:\Users\Tyler\VirtualBox VMs\Ubuntu 12.04 32-bit\Snapshots\2014-01-30T19-59-05-976647800Z.sav' is invalid (VERR_FILE_NOT_FOUND). Deleted the saved state prior to starting the VM. I tried deleting the file as it said, but none of the snapshots would open still. The file is still in my recycling bin. What can I do? Also, I took the 1/31 snapshot today before I deleted the previous one.

  • Initrd and Initramfs

    - by nitins
    I have read about the differences between the two from stackoverflow. But I am still finding it difficult to understand tmpfs and the real advantages of initramfs over initrd. I find that on RedHat EL 5 or Ubuntu 12.04, I have only initrd files in /boot. However RedHat EL 6 has both intird and intramfs files. Does that mean only Redhat 6 has implemented intiramfs and we still have initrd image there?

  • Config deployment on multiple servers.

    - by user66601
    I have multiple servers in WEB cluster (identical configuration for all of them, despite the IP) How do you deploy changes in configs on multile servers? I make the new config, then create config per every server (placing correct IP), and next: upload them on every server, replacing old ones (rsync over ssh) set on every server a job which reloads webserver at the same time (servers use ntp). - this done by issuing commands by script (to save time for logging in) before adding a job for server reload - there's checksum test of the config on the server) - an a notification in case of fail How do you see such method? What should be the "professional way :) ? (I don't say my way doesn't work... it works and saves my time not used for logging on every webserver.) Regards,

  • How do I install yum on Redhat Enterprise 4?

    - by Bob Cross
    For historical reasons, one of the machines that I manage has a Redhat Enterprise 4 boot disk (among others). Every now and then, we have to boot into RHEL4 to bring up some of the legacy software that we support and connect to. Since it's a fringe system, the Redhat support has long since lapsed and I can't convince myself that it would be worth paying just to get RPMs that I can go and get for myself. That said, the default RHEL tools are heavily biased against letting you do exactly that. I would like to install yum and use that as my package discovery and installation. So, is there an installation guide to integrating yum with an older RHEL 4 system?

  • Why does deleting from the command line take significantly less time than from a GUI?

    - by Jordan Plahn
    So this is probably the dumbest question you'll read today, but it's something I just wondered about as I was deleting a dozen or so images from my computer. With a quick rm -rf command on the directory's contents, all the images were gone in a snap. When I drag the same dozen or so images to a trash can/recycle ban, it takes sometimes 10 seconds or more. Now I'm sure some of it comes from the overhead of the GUI and such, and some of it may be the fact that the file still "exists" in some form if it's put into the recycle bin, but is there anything else that accounts for such a huge time disparity? Are "rm" and "delete" just such fundamentally different commands so I'm trying to compare apples and oranges? Enlighten me, please!

  • Full Apache config migration

    - by Victor Rashkov
    I searched alot and didn't find an applicable answer. I have a working LAMP setup on Ubuntu machine and I have to migrate to a new server in a different country. The old server is 11.10, the new server is 12.04LTS. My problem is that I simply can not remember the steps I followed when I configured the current server which is not the basic LAMP install. It is Apache with FastCGI, SuEXEC, a GD library, worker MPM and all sitting on top of a mhddfs system. There are also other configs I've changed and I can not recall what they are. Because of the complexity of the setup, my attempts to migrate to the new server fail. I get permissions errors, cgi problems etc. Therefore my question is : Is there a sane way to simply tar a full backup of the current web server installation, including MySQL, Php amd the apache server with all configs, and then move it to the new machine? I shall be forever thankful on any advise. So far non of thise I found here gave me an answer. Thanks!

  • Router that allows custom Dynamic DNS server [closed]

    - by Thuy
    I've made my own DDNS service and it works fine using an application running on clients to update the IP. But if for some reason I don't have the choice of using my software and instead I need to use a router to update the IP, it becomes troublesome. For example, I needed to setup IPsec from a customer to me and the customers router/firewall (netgear srx5308) has a dynamic IP which is given from the ISP which can't offer static IPs. So it needs to use dynamic dns for it to work. In this case there really isn't a client to run the software on since it's a router/firewall. Unfortunately it seems that most routers are rather unfriendly towards custom DDNS solutions and most offer only dyndns.com or similar templates. Which was the case with this router too. Leaving me with no way to use my own dynamic dns server IP. I have the option of switching out the customers router and I've been looking around for alternatives and other routers/solutions and I was wondering if anyone on this great site might have been in a similar situation or might just know about some router/firewall that is more friendly towards custom ddns solutions that I might be able to use. Thanks in advance for any help or guidance!
