  • How to set up multiple DNS servers on an intranet

    - by Brent
    We have an Active Directory network, with a mixture of Windows DNS, linux BIND servers, and want to use OpenDNS as our external DNS provider. I am wondering What is the best way to set up these servers (regarding forwarders, recursion, etc.)? Active Directory is our main internal DNS for our domain, and has 3 redundant servers. DHCP and all our servers use these as their DNS servers. Then we have a legacy AD server from an old network that is still authoritative for a bunch of domains. Finally, we have a couple of Linux Bind servers that are authoritative for a bunch of websites we host. Should our main AD servers point to our legacy AD server, which points to one of our BIND servers, which points to the other BIND server, which finally points out to openDNS? Or should our main AD servers point to all of these directly? - or is there a better option? What happens if a domain is listed in 2 places? Does DNS process the forwarders in order? What about root servers - if I want to use OpenDNS for "everything else", do I just list them as the last forwarders, and delete the root servers from all my DNS servers? How does recursion work - in this scenario, should I be using recursion or not?

  • Postfix relay gives error 450 while it should be 550

    - by dieter-be
    Hi, we use postfix to do relaying. We get several messages like the following in /var/log/mail (slightly edited) Apr 13 13:30:29 linserver postfix/smtpd[1064]: NOQUEUE: reject: RCPT from unknown[$ip]: 450 4.1.1 <[email protected]>: Recipient address rejected: undeliverable address: host domain.be [$ip] said: 550 <[email protected]>: Recipient address rejected: User unknown in virtual mailbox table (in reply to RCPT TO command); from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<BLUESTREAK.domain.local> Now, when the master mail servers gives a 550, claiming that the user does not exist, I want the relay to also give a 550 back. What happens now is that it seems to return a 450, causing clients to keep messages queued, keep trying and only notify users after a certain period has passed. According to what I could find, the soft_bounce could cause this. But we have not enabled this option (and by default it's off according to postfix docs) It might also have something to do with the *_reject_code postconf values. Especially since the log message complains the unknown ip. But as you can see in the postconf output below, smtpd_sender_restrictions and smtpd_client_restrictions are empty. So even if it would try to do any restrictions there, 550 is the "worst" error going on, so that's what I expect to be returned to the client. postconf: http://sprunge.us/JYgB Thanks, Dieter

  • APC not caching many files

    - by tetranz
    Hello I have a Drupal site running on a VPS at Linode with PHP 5.2.10 and APC 3.1.6. It never caches more than about 25 files and barely uses any of its available memory. Drupal has hundreds of php files. I have another server where APC seems to work well and does indeed cache hundreds of files. The only difference with that site is that it runs Ubuntu 10.04 and php 5.3.2. The config settings are the same. What could be wrong? I'll paste the config from apc.php below. This is after hitting multiple parts of Drupal. Thanks APC Version 3.1.6 PHP Version 5.2.10-2ubuntu6.5 APC Host xxx.example.com Server Software Apache/2.2.12 (Ubuntu) Shared Memory 1 Segment(s) with 32.0 MBytes (mmap memory, pthread mutex locking) Start Time 2010/12/02 11:32:17 Uptime 3 minutes File Upload Support 1 File Cache Information Cached Files 21 ( 1.4 MBytes) Hits 169 Misses 21 Request Rate (hits, misses) 1.00 cache requests/second Hit Rate 0.89 cache requests/second Miss Rate 0.11 cache requests/second Insert Rate 0.17 cache requests/second Cache full count 0 User Cache Information Cached Variables 0 ( 0.0 Bytes) Hits 0 Misses 0 Request Rate (hits, misses) 0.00 cache requests/second Hit Rate 0.00 cache requests/second Miss Rate 0.00 cache requests/second Insert Rate 0.00 cache requests/second Cache full count 0 Runtime Settings apc.cache_by_default 1 apc.canonicalize 1 apc.coredump_unmap 0 apc.enable_cli 0 apc.enabled 1 apc.file_md5 0 apc.file_update_protection 2 apc.filters apc.gc_ttl 3600 apc.include_once_override 0 apc.lazy_classes 0 apc.lazy_functions 0 apc.max_file_size 1M apc.mmap_file_mask apc.num_files_hint 1000 apc.preload_path apc.report_autofilter 0 apc.rfc1867 0 apc.rfc1867_freq 0 apc.rfc1867_name APC_UPLOAD_PROGRESS apc.rfc1867_prefix upload_ apc.rfc1867_ttl 3600 apc.shm_segments 1 apc.shm_size 32M apc.slam_defense 1 apc.stat 1 apc.stat_ctime 0 apc.ttl 0 apc.use_request_time 1 apc.user_entries_hint 4096 apc.user_ttl 0 apc.write_lock 1

  • How to create RPM for 32-bit arch from a 64-bit arch server?

    - by Gnanam
    Our production server is running CentOS5 64-bit arch. Because there are no RPM available currently for SQLite latest version (v3.7.3), I created RPM using rpmbuild the very first time by following the instructions given here. I was able to successfully create RPM for 64-bit (x86_64) architecture. But am not able to create RPM for 32-bit (i386) architecture. It failed with the following errors: ... ... ... + ./configure --build=x86_64-redhat-linux-gnu --host=x86_64-redhat-linux-gnu --target=i386-redhat-linux-gnu --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info --enable-threadsafe checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes checking for style of include used by make...

  • LAMP server VM issues

    - by nullArray
    After getting a recommendation to salvage a wiki by installing a LAMP server, I went on the prowl for a good virtualized one. I used the VMware Player version. Since the windows box has Bonjour, I can, for example, go to http://lamp.local. and it works see the web client. The problem is, I can't ssh to a directory to scp the files I need, mount a usb thumbdrive (usbfs is unsupported) nor get samba working. I can't even update the ubuntu installation, it fails. I've tried bridged, nat and host-only networking settings in VMware Player. Bridged gives me an undefined IP, while the other two each have different IPs. All three settings allow me to access the web config, but none of them give me samba access. Windows usually freezes, then reports that it cannot connect. I'd rather not wipe a box to do a dedicated install, is there I way I can get this VM working, or are there better LAMP VMs out there? This one came already working and set up with VMware Player, so I thought it would be perfect... Thanks,

  • Explorer.exe not starting after login on Windows Server 2003 (Terminal Services and console)

    - by Pepperoni Icecream
    When users login to a Windows Server 2003 R2 running Terminal Services they have a blank desktop. Upon inspection, explorer.exe is not running. When I login as administrator, using either RDP or to the console, I am having the same issue. I can pull up the taskman and start explorer.exe manually. I have another Terminal Server setup exactly the same way (same apps, settings, GPO, etc . . .) the only difference is we deployed Symantec Endpoint Client 11.0.5 on Friday. For some reason the working Terminal Server is still on 11.0.4, but the suspect server received the 11.0.5 client upgrade. I checked the eventviewer for any relevant explorer.exe entries to no avail. It seems that if SEP is preventing explorer.exe from starting at login it would do the same for the domain admin starting explorer.exe from the taskman. I disabled the SEP client and services on the server and issued smc -stop and tried logging in again. Still no explorer.exe. So I'm not sure if the client upgrade is relevant but it is worth mentioning since that was the last system change. The 2 servers are members of a NLB group. I took the bad terminal server out of the group until the issue is resolved. Actually stopped the host using NLB manager Any help is appreciated.

  • what web based tool, to allow a non-technical user to manage authorized keys files on a Linux (fedora/centos/ubuntu/debian) server

    - by Tom H
    (Edit: clarification below) We have a number of groups of developers that change frequently, and a security policy to require individual logins to servers using rsa or dsa public keys, which is achieved via the standard method of adding id_dsa.pub to their authorized keys file. I am using chef to sync the user accounts across machines, however our previous method of using webmin to manage the user passwords is not designed for key based auth, and hence is not easy to use for non-technical users. The developers are logging in from the WAN using ssh, they can either provide their own key, or an administrator will send them a private key. The development machines are located in the cloud and we have a single server available to host the master set of accounts. Obviously I could deploy ldap or other centralised authentication system, but that seems a bit over blown when webmin worked well for the simple case. It is easy to achieve synchronised users, groups and passwords across a bunch of low security development boxes using webmin clustered users and groups. However looking at the currently installed webmin it is not so easy to create the authorized keys as it is to create user accounts and passwords. (its possible, but its not easy - some functionality is in the usermin module, or would required some tedious steps) Ideally I'd like a web interface that is pretty much dedicated to creating users and groups, and can generate key pairs on the fly, and can accepted pasted in public keys to add to the users authorized keys file. If the tool sync'ed the users and keys as well, that would be great, but I can use chef to do that part if the accounts are created correctly on the "master" server.

  • Understanding mail failure notices, 554

    I'd like to confirm the meaining of a mail failure notice. Here's the message Hi. This is the qmail-send program at mydomain.com I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <[email protected]>: 1.2.3.4 does not like recipient. Remote host said: 554 <[email protected]>: Relay access denied Giving up on 1.2.3.4 The way I understand this is, that 1.2.3.4 is not setup to receive mail for this domain. dig domain.com MX shows ;; ANSWER SECTION: domain.com. 6245 IN MX 10 mail.domain.com. domain.com. 6245 IN MX 20 mx.anotherdomain.com. (1.2.3.4 is mx.anotherdomain.com.). The puzzling part is that I have reports that messages sent from gmail get delivered to this address. P.S. Is this a proper question for serverfault?

  • who has files open on a linux server

    - by Robert
    I have the fairly common task of finding who has files open on our Linux (Ubuntu ) file server in our Windows environment. We use Samba on the network and I use Putty from my workstation to establish a shell window to run bash scripts. I have been using something like this to find what files are open: (this returns a list of process ids with each open file) Robert:$ sudo lsof | grep "/srv/office/some/folder" Then, I follow up with something like this to show who owns the process: (this returns the name of the machine on the network using the IP4 protocol who owns the process) Robert:$ sudo lsof -p 27295 | grep "IPv4" Now I know the windows client who has a file open and can take action from there. As you can tell this is not difficult but time consuming. I would prefer to have a windows application I can run that would just give me what I want. So, I have been thinking about creating some process I can run on Linux that listens on a port and then returns a clean list of all open files with the IP address of the host who has the file open. Then, a small windows client application that can send the request on the port. It seems like this should be a very common need but I can not find anything like this that has been done before. Any suggestions?

  • Failing to send email on Ubuntu box (Karmic Koala)

    - by user25312
    I have a home network with an XP and Ubuntu (9.10) box. I have created a small test php script for checking that I can send emails from my machine. I am using the same php.ini file with the same [mail settings], yet the file works on my XP box, and fails on the Ubuntu box. I have included the script here, hopefully, someone can spot whats going wrong: <?php // send e-mail to ... $to="[email protected]"; // Your subject $subject="Test Email"; // From //$header="from: test script"; $header='From: host-email-username@hostdomain_here' . "\r\n" . // Your message $message="Hello \r\n"; $message.="This is test\r\n"; $message.="Test again "; // send email $sentmail = mail($to,$subject,$message,$header); // if your email succesfully sent if($sentmail){ echo "Email Has Been Sent ."; } else { echo "Cannot Send Email "; } ?> The emails have been spoofed for obvious reasons, but otherwise, the script is exactly as the one I tested [Edit] I have since installed mailutils package on my Ubuntu box, now the script runs and returns 'Email has been sent'. However, the mail never arrives in my mail inbox (I've waited 1 day so far). Is there something else I need to be looking at?

  • Physical-to-virtual for personal use

    - by Journeyman Geek
    One of my current projects involves reducing the number of old computers lying around. So far, the office systems have been downsized from 5 to 2. One system which had no data on it was dumped entirely, while three other identical boxes were consolidated into to one (I swap hard drives as needed and they just work(tm)). I want to make further cuts. The physical systems in question all run windows xp sp3, and were old Pentium 4s with 256 MB of RAM. Currently, I have got a VirtualBox running on another system. My intention is to migrate all services to that. We can assume that disk space and RAM on the host is not an issue. I'd rather not go with a client-server physical-to-virtual (P2V) method like what VirtualBox uses now. I have a few specific concerns as well - specifically whether I'd need to reactivate or sysprep for dissimilar hardware first. An offline tool for imaging (Windows or Linux) would not be an issue since the drives could be mounted onto another system I have anyway or I could use a LiveCD. What would be my options for P2V conversion, and what would I need to keep in mind when doing this?

  • Installing Tomcat on CentOS 5

    - by andybaird
    Disclaimer: I am not a server admin, I am a windows user that has lead a life of sinful installation wizards and drag and drop I'm attempting to install Tomcat on CentOS 5 hosted by a MediaTemple dedicated virtual server. I basically followed this guide: Installed jpackage and configured the yum.repo.d jpackage file to set enabled=1 Used yum to install java (yum install java) Downloaded the binary distribution of tomcat with "wget http://archive.apache.org/dist/tomcat/tomcat-6/v6.0.14/bin/apache-tomcat-6.0.14.tar.gz" set JAVA_HOME to point at the jdk location I found with "export JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/" I gunzip/untar the Tomcat files and run ./startup.sh to start the Tomcat server. That is supposed to put the Tomcat server at myserver.com:8080 - however, I just get a could not contact host error when I try to browse to it (or when I try 'curl localhost:8080' from SSH) After I type ./startup.sh, here is the console output: [root@myserver bin]# ./startup.sh Using CATALINA_BASE: /root/apache-tomcat-6.0.14 Using CATALINA_HOME: /root/apache-tomcat-6.0.14 Using CATALINA_TMPDIR: /root/apache-tomcat-6.0.14/temp Using JRE_HOME: /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/ [root@myserver bin]# Is there a step I have missed here?

  • Coldfusion 9 losing connection to MySQL 5 database server a couple of weeks after the server is started

    - by user1503757
    We get the following Coldfusion error message after our server have been running for a couple of weeks: Error Executing Database Query.Could not create connection to database server. Attempted reconnect 3 times We run Coldfusion Enterprise 9 on a one year old XServer with Snow Leopard and MySQL 5 The server has about ten DSN set up in the Coldfusion Administrator All local, with default advanced settings, and host set to "localhost" The server is not under heavy load. The strange thing is that after a restart of the server, everything works fine. Then after a week or so, some databases will stop working, in the sense that Coldfusion cannot create a connection to them. If I then go to the Coldfusion Administrator and click "Verify all datasources", I will get that only 2 or 3 got verified, the other ones failed, and it is always the same datasources that can't be verified when the server starts to behave like this if I try to verify again, BUT NOT neccessary the same datasources that couldn't be verified the last time the server behaved like this. I know about the setting "max_connections" and we have included a line for that setting in the MySQL config file and set it to 2000, and when we read it by a query it says "2000", so that can't be the problem. Anyone?

  • IIS7 binding to subdomain causing authentication errors (TFS 2010)

    - by Tommy Jakobsen
    I'm trying to bind a IIS web site (Team Foundation Services 2010) to a subdomain, which is causing authentication errors. First I'll explain what I've done to set it up. This is the fist time I do this, so please correct me if I'm wrong. The web server is a stand-alone Windows Server 2008 R2 x64, running IIS7 with .NET Framework 4. I have the following A-records, pointing to my server: server.mydomain.com *.server.mydomain.com So all subdomains of server.mydomain.com points to the server. In IIS7 I have a web site (TFS 2010) on port 8080, with a virtual directory (named tfs) that is using Windows Authentication. I have one binding on the web site pointing to all unassigned IP addresses, port 8080 and having a host name of tfs.server.mydomain.com. Now, shouldn't I be able to access the virtual directory through: http://tfs.server.mydomain.com/tfs That is not working. However, I can access it through: http://tfs.server.mydomain.com:8080/tfs But, it won't let me authenticate using a Windows account (Server\Username). A windows account that I can authenticate with, when accessing the site through http://localhost:8080/tfs. What am I missing here?

  • Single application through OpenVPN tunnel (Debian Lenny)

    - by mikael
    I'm using Debian Lenny and I want to tunnel rtorrent only through a OpenVPN tunnel. I have a tunnel running, the config file looks like this: client dev tun proto udp remote openvpn.xxx.com 1194 resolv-retry infinite nobind persist-key persist-tun ca /etc/openvpn/xxx/keys/ca.crt cert /etc/openvpn/xxx/keys/client.crt key /etc/openvpn/xxx/keys/client.key tls-auth /etc/openvpn/xxx/keys/tls.key 1 ns-cert-type server comp-lzo verb 3 auth-user-pass script-security 3 reneg-sec 0 My idea is that I could run a sockd proxy internally that redirects traffic to the openvpn tunnel. I could use the *nix "proxifier" application "tsocks" to make it possible for rtorrent to connect through that proxy (as rtorrent doesn't support proxies). I have trouble configuring sockd as my IP inside the VPN changes every time I connect. This is a config file someone said would help: http://ircpimps.org/sockd.conf As my IP changes at each connect I don't know what to put in that config file. I have no control over the host side config file. Any help wanted. Any other method is very welcome.

  • Disable IPv6 on Debian VPS (Virtuozzo!)

    - by chris_l
    I have a Debian Lenny VPS, that's running virtualized by Parallels/Virtuozzo. Currently, the network interface doesn't have an IPv6 address - and that's good, because I don't have an ip6tables configuration. But I assume, that I could wake up one day, and ifconfig will show me an ipv6 address for the interface - because I have no control over the kernel or its modules - they're under the control of the hosting company. That would leave the server completely vulnerable to attacks from IPv6 addresses. What would be the best way to disable IPv6 (for the interface or maybe for the entire host)? Usually I would simply disable the kernel module, but that's not possible in this case. Update Maybe I should add, that I can use iptables and everything normally (I'm root on the VPS), but I can't make changes to the kernel or load kernel modules because of the way Virtuozzo works (shared kernel). lsmod always returns nothing. I can't call ip6tables -L (it says that I need to insmod, or that the kernel would have to be upgraded). I don't think, that changes to /etc/modprobe.d/aliases would have any effect, or do they? Networking Config? I thought, that maybe I can turn IPv6 off from /etc/network/... Is that possible? I just see, that they've set up avahi, so I should probably change the setting use-ipv6=yes to "no" in /etc/avahi/avahi.conf (?) Has anybody already tried this solution, and can I rely on it? I don't know too much about avahi. Would it actually have any effect? Or could it even bring my entire interface down, once IPv6 is enabled by the kernel?

  • I am under DDoS. What can I do?

    - by Falcon Momot
    This is a Canonical Question about DoS and DDoS mitigation. I found a massive traffic spike on a website that I host today; I am getting thousands of connections a second and I see I'm using all 100Mbps of my available bandwidth. Nobody can access my site because all the requests time out, and I can't even log into the server because SSH times out too! This has happened a couple times before, and each time it's lasted a couple hours and gone away on its own. Occasionally, my website has another distinct but related problem: my server's load average (which is usually around .25) rockets up to 20 or more and nobody can access my site just the same as the other case. It also goes away after a few hours. Restarting my server doesn't help; what can I do to make my site accessible again, and what is happening? Relatedly, I found once that for a day or two, every time I started my service, it got a connection from a particular IP address and then crashed. As soon as I started it up again, this happened again and it crashed again. How is that similar, and what can I do about it?

  • lm-sensors - always returns 32 degrees (celsius) for temperature

    - by mopoke
    On my VIA EPIA motherboard (using VIA VT8231 ISA bridge), I get strange output for the lm-sensors temperature reading. It always returns 32 degrees (celsius). I have previously had correct output for temperature (my munin graphs show temperatures typically in the range of 50 to 60 degrees. I've tried uninstalling (and purging) the lm-sensors package, have re-run sensors-detect a number of times and rebooted but nothing seems to change the output. I am running Ubuntu Karmic Koala (9.10).

  • Unable to ping domain.local, but can ping server.domain.local

    - by Force Flow
    I have a single windows 2008 server running active directory, group policy, and DNS. DHCP is running from the firewall (this is because there are multiple branch locations, and each location has its own firewall supplying DHCP. But, for this problem, the server and workstation are at the same location). On an XP workstation, if I try to visit \\domain.local or ping domain.local, the workstation can't find it. A ping returns Ping request could not find host domain.local. If I try to visit \\server or \\server.domain.local or ping server or server.domain.local, I'm able to connect normally. If I ping or visit domain.local on the server, I'm able to connect normally. A-Records are in place in the DNS service for server, domain.local, and server.domain.local. A reverse lookup zone also is enabled and PTR records are in place. If I wait 20-30 minutes, I am eventually able to ping and visit domain.local--but, when attempting to ping, it takes 30 second to return an IP address. I am also unable to join a new workstation to the domain during this wait period. If I try, the error message returned is "network path not found". Is there something I'm missing?

  • Plesk wildcard subdomain not working

    - by avdgaag
    I'm trying to set up a wildcard subdomain on my VPS. Ultimately I want to end up with this: main site: my.domain.tld subdomain: sub1.my.domain.tld - should end up serving my.domain.tld/sub1 I am using plesk 8.6. I have created a DNS A record pointing at my VPS' IP. I have then restarted the DNS server and waited up to 24 hours. But trying ping sub1.my.domain.tld results in an unknown host error. So I know there's more stuff involved, configuring apache etc. But so far, I cannot even get the subdomain working at all, let alone serve up the right content. I have also tried a CNAME record, to no effect. I have also tried creating a regular subdomain with a fixed name, which also does not work. Pre-configured subdomains DO work, like ftp.my.domain.tld or mail.my.domain.tld. I am clearly missing something here, but my hosting provider charges a small fortune for any support request not involving hardware physically burning down, so I'm hesitant to ask them. Any ideas?
