  • SQL Server Issue: Could not allocate space for object ... primary filegroup is full

    - by Luke
    Trying to figure out a problem at an office that has SQL Server 2005 installed on Windows SBS Server 2008. Here's the setup: It's an office, and the person who set this all up is nowhere to be found. I'm the best hope they have... One of the programs they use on a workstation gives them an error of "Could not allocate space for object 'Billing' in database "MyDatabase" because primary filegroup is full" when trying to save an entry in their software. I searched around for hours, looking for possible solutions. One was to check for available disk space, and another was to defrag. I checked the hard drives on the server, and there is plenty of space free. I also defragged, which may have helped the problem somewhat. It's hard to say, because it seems like with the nature of the error, if you try over and over you might get it to actually save. My next step was to try to see if autogrowth was enabled on the database. This would seem to be a likely / possible solution, but I can't access the database! If I run the SQL Management Studio, I can log in as my Windows user and view the list of databases. However, if I try to do anything (actually view the database, view the properties, add or edit users), I get errors that I don't have permission. For what it's worth, I also tried runing Management Studio as Administrator, in case that would help. No difference, though. Now, what I'm guessing is going on -- from my limited knowledge of SQL and from reading online -- is that though I'm logged in as a Windows administrator, that account does NOT have SQL access. I do see a list of SQL users, including SA, but I again don't have permission to add one or to change the password on an existing one. And nobody at the office has any idea what the SQL passwords could be. So... here's my thinking thus far: 1 - The "Could not allocate" error likely points to a database that needs to be allowed to autogrow. Especially since I verified there is plenty of free space and the HD has been defragmented. 2 - Enabling autogrow would be very easy to do if I had the proper access within SQL Management Stuido. That leads me to this link: http://blogs.technet.com/b/sqlman/archive/2011/06/14/tips-amp-tricks-you-have-lost-access-to-sql-server-now-what.aspx It sounds like it's a step-by-step guide for giving me the access I need to SQL. I'm guessing that if I followed this guide, I would be able to then log in to the SQL server via Management Studio with the proper permissions, and would be able to enable autogrow (or simply view the status of the existing database), and hopefully solve the "Could not allocate space" problem! So I guess I have a few questions: 1 - Would you guys agree with my "diagnosis"? Think I'm barking up the right tree? 2 - Is there any risk at all in hurting / disabling / wrecking the current SQL database or setup with me going through the guide to regain SQL access? I understand that per the guide, I would have to temporarily shut down SQL, so obviously it wouldn't be accessible during that time. But it wouldn't be worth the risk if there's a chance I could mess anything up... Like I said, the workstations ARE currently accessing the database somehow, but nobody knows with what login info or anything. Basically, it's set up, it works (usually), but if they had to reload the software, nobody would know how. Any feedback would be appreciated!! The problem is such that it's not an emergency for them, but an annoyance. If I could fix it, it would be wonderful. But if not, I think they'll manage, especially as they are going to eventually stop using this software. Thank you so much for your time! Luke

  • Rails 3 shows 404 error instead of index.html (nginx + unicorn)

    - by Miko
    I have an index.html in public/ that should be loading by default but instead I get a 404 error when I try to access http://example.com/ The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved. This has something to do with nginx and unicorn which I am using to power Rails 3 When take unicorn out of the nginx configuration file, the problem goes away and index.html loads just fine. Here is my nginx configuration file: upstream unicorn { server unix:/tmp/.sock fail_timeout=0; } server { server_name example.com; root /www/example.com/current/public; index index.html; keepalive_timeout 5; location / { try_files $uri @unicorn; } location @unicorn { proxy_pass http://unicorn; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } } My config/routes.rb is pretty much empty: Advertise::Application.routes.draw do |map| resources :users end The index.html file is located in public/index.html and it loads fine if I request it directly: http://example.com/index.html To reiterate, when I remove all references to unicorn from the nginx conf, index.html loads without any problems, I have a hard time understanding why this occurs because nginx should be trying to load that file on its own by default. -- Here is the error stack from production.log: Started GET "/" for 68.107.80.21 at 2010-08-08 12:06:29 -0700 Processing by HomeController#index as HTML Completed in 1ms ActionView::MissingTemplate (Missing template home/index with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml, :haml], :formats=>[:html], :locale=>[:en, :en]} in view paths "/www/example.com/releases/20100808170224/app/views", "/www/example.com/releases/20100808170224/vendor/plugins/paperclip/app/views", "/www/example.com/releases/20100808170224/vendor/plugins/haml/app/views"): /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/paths.rb:14:in `find' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/lookup_context.rb:79:in `find' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/base.rb:186:in `find_template' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/render/rendering.rb:45:in `_determine_template' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/render/rendering.rb:23:in `render' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/haml-3.0.15/lib/haml/helpers/action_view_mods.rb:13:in `render_with_haml' etc... -- nginx error log for this virtualhost comes up empty: 2010/08/08 12:40:22 [info] 3118#0: *1 client 68.107.80.21 closed keepalive connection My guess is unicorn is intercepting the request to index.html before nginx gets to process it.

  • libvirt qemu/kvm migration problem

    - by Panda
    I am using kvm and libvirt on my Dell server. Now i am trying to migrate one virtual machine from a physical server to another. However, I failed everytime. In virsh on physicalServer1, I typed: virsh # migrate virtualmachine1 qemu+ssh://username@physicalServer2/system error: operation failed: migration to 'tcp:physicalServer2:49163' failed: migration failed Then I searched FAQ part on libvirt.org. It says: error: operation failed: migration to '...' failed: migration failed This is an error often encountered when trying to migrate with QEMU/KVM. This typically happens with plain migration, when the source VM cannot connect to the destination host. You will want to make sure your hosts are properly configured for migration (see the migration section of this FAQ) I managed to ssh physicalServer2 from a shell on virtualmachine1 so the above red part did not explain my failure. I also open ports on physicalServer2, iptables -L shows following information: Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:bootps ACCEPT tcp -- anywhere anywhere tcp dpt:bootps ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:bootps ACCEPT tcp -- anywhere anywhere tcp dpt:bootps ACCEPT tcp -- anywhere anywhere state NEW tcp dpts:49152:49215 Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere 192.168.122.0/24 state RELATED,ESTABLISHED ACCEPT all -- 192.168.122.0/24 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable ACCEPT all -- anywhere 192.168.122.0/24 state RELATED,ESTABLISHED ACCEPT all -- 192.168.122.0/24 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable Chain OUTPUT (policy ACCEPT) target prot opt source destination The /var/log/libvirt/qemu/virtualmachine1.log on physicalServer2: 2011-05-06 13:37:30.708: starting up LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/kvm -S -M pc-0.14 -enable-kvm -m 2048 -smp 1,sockets=1,cores=1,threads=1 -name openjudge-test -uuid a8c704bc-a4f9-90db-3e57-40e60b00aac1 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/virtualmachine1.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=readline -rtc base=utc -boot c -drive file=/media/nfs/virtualmachine1.img,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=20,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=00:16:36:8a:22 :a0,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -vnc 127.0.0.1:2 -vga cirrus -incoming tcp:0.0.0.0:49163 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 char device redirected to /dev/pts/0 2011-05-06 13:37:30.915: shutting down The /var/log/libvirt/qemu/virtualmachine1.log on physicalServer1 is empty.

  • Issues getting a Cisco WLC 5508 to find AIR-LAP1142N

    - by user95917
    hoping someone can help me with a problem here. I'm attempting to setup a test (loan from Cisco) wireless network. Here's what i've got/done: 5508 Controller - Service Port IP set to 10.74.5.2 /24. Management IP set to 10.74.6.2 /24 with a default gateway of 10.74.6.1. Virtual IP set to 1.1.1.1. Copper SFP in slot 7, CAT5 (known good) going from there to port 1/0/47 on the switch. Green lights on both ends. 2960-S Switch - Vlan1 - 10.74.6.1 /24. dhcp pool 10.74.6.0 /24, default router 10.74.6.1. excluded-address 10.74.6.1, 10.74.6.2. 1/0/4 on the switch is set to switchport mode access and no shut. 1/0/47 on the switch is setup to switchport mode trunk and no shut. 1/0/4 has a CAT5 (known good) cable going from there to the AP. When I do a sh cdp nei from the switch, i can see the AP and Controller listed. When i configure my PC's nic to 10.74.5.5, and plug a cable from my nic to the SP port on the controller i can get on the device via the gui. In there, the only errors/info that show up in the trap are: Link Up: Slot: 0 Port: 7 Controller time base status - Controller is out of sync with the central timebase. I've manually set the time but apparently that's not quite the problem (or at least not the entire problem). When i plug the AP in, i see on the switch console that it grants it power, it sees it connect...but the controller won't see it for some reason. From what i've read you shouldn't have to do anything to the AP as it's managed by the controller...but i'm not sure what setting I'm missing for it to work. The AP light on top is continually cycling green, red, yellow. When I first start it up, it blinks green for 20 or so seconds, then goes to solid green for another 20 seconds or so, then flashes blue, green, red for awhile...but always ends up goinn back to the standard, green, red, yellow. Does anyone see any obvious issues with my setup or have any suggestions as to why i might be having a problem? Thanks for your help!

  • USB ports causing Wireless and Mobile Phone tethering drop out

    - by chrolli
    I have a problem with my USB ports and I can't seem to pinpoint the problem. I'm hoping that I can get some idea as to how to troubleshoot my problem. Problem description: I recently bought a USB Wireless Adapter in order to connect my Desktop PC to the WLAN. The dongle keeps dropping off connection regularly on average once a minute. And the connection is slow. What I've tried: I installed a network scanner to determine signal strength. The PC/adapter combo is getting about 70% signal strength. I have a laptop that has an internal Wireless adapter. I moved the laptop near the location of the PC. The signal strength was above 90%. I installed the USB adapter on the laptop. I placed the laptop near the location of the PC. The signal strength was above 80%. And there is no drop out issue. I've isolated the problem to be on the PC. I used internet tethering on my mobile phone in order to test the USB ports. I get the same problem, themobile phone keeps dropping in and out. I plugged the adapter and phone on all USB ports, and it is still dropping out on all ports. I've isolated the problem to be the Motherboard, USB hub. I updated the BIOS, and USB driver. Still dropping out. I noticed that when I used the mobile phone tethering method, the phone (iphone 5) is guarenteed to drop out and does not appear to charge if I jiggle the the 8-pin connector on the base of the phone. If I push the pin tightly on the phone, the phone starts charging, as soon as I let go, it stops and drops out from the PC. This is strange because this doesn't happen when it is plugged to the powerboard. Which means that the 8 pin connector is fine. I'm not sure what the problem is. I assume that it is to do with the USB ports not supplying enough power which in turn causes the devices to intermittently drop out. The reason I say this is because the USB cable works fine when plugged into a powerboard with enough power supplied to the phone. Only when it is plugged into the USB port on the PC, does it drop out. My motherboard is Asus P8z68-v le. My Wireless adapter is the D-link DWA131. I can't seem to find any settings in the BIOS to increase the south bridge voltage so as to supply more power to the USB ports. Although this problem only occurs when I'm trying to hook up to a device supplying internet connection. My USB HDD, Flash drives, and Mouse and Key are working fine! Any suggestions please?

  • The server rejected the session-establishment request: WCF hosted on IIS

    - by Dave Hanna
    Background: I'm working on a project where we have about a dozen distinct WCF services implemented in an IIS application, communicating over net.tcp on the default port (808), using the Microsoft Net.Tcp Port Sharing Service. I recently added a self-test method to the base class of each of these services so that I could remotely hit the service and get back a status string verifying that it was in operation. We implement this app in a ladder of environments - Development, QA, UAT, and finally production. My problem: My test program, which instantiates a connection to each service in turn and invokes the self-test method, works fine on all the environments below production. We recently moved the app to production, and I'm getting a weird error that I can't explain: On the first of the services that I hit, I get back an exception: "The server at [URL] rejected the session-establishment request". All the other services respond fine. I initially thought there was something wrong with the particular service that was failing, but I tried rearranging the list of services into a different order, and it SEEMS to always be the first service that I hit that fails. (I say SEEMS because it think once in the early iterations of testing, I saw it happen on the second service that it hit. But I haven't been able to reproduce that.) I've looked at application startup delays, and that doesn't seem to be the problem, because I can come back and run the test again as soon as it finishes - a delay of only a minute or two - and get the same error. Also, in the lower level environments, there is a start up delay of probably 30 seconds to a minute, but the result still comes back as expected. I've tried accessing the services over http from INetManager, and I get intermittent failures on all the services - a particular service will return a yellow screen of death on on invocation, then come up with the expected link to the WSDL on the next one seconds later. I'm completely at a loss to explain this behavior, or how to resolve it. I've googled the error message, and not found anything helpful. It may be a configuration issue - the production servers are newly provisioned VM's, and we may not have the config exactly right (whereas all the lower level environments have been running this and other similar apps for some time), but I have not idea what to look for. I've looked at the properties of the app pool that the app is running on and compared it to the lower level environments without finding any differences. If somebody can point me in the right direction, you would have my undying gratitude.

  • Can't get Monit to work

    - by Andrea
    I am trying to configure Monit on my local machine to get a taste at how it works, but I have some issues. What I am trying to do is to get any evidence that Monit is up and running correctly and is actually monitoring something. So my /etc/monit/monitrc looks like set daemon 60 set logfile /var/log/monit.log set idfile /var/lib/monit/id set statefile /var/lib/monit/state set eventqueue basedir /var/lib/monit/events slots 100 set httpd port 2812 and allow username:password check process apache2 with pidfile /usr/local/apache/logs/apache2.pid start program = "/etc/init.d/apache2 start" stop program = "/etc/init.d/apache2 stop" if failed port 6543 protocol http then exec "/usr/bin/touch /tmp/monit" If I understand correctly, since apache does not listen on port 6543 (it is just a random number) I should get an error, and as a consequence the file /tmp/monit should be created. So I start monit by sudo service monit start sudo monit monitor apache2 Unfortunately no such file is created. Instead the web console shows an error for apache - execution failed. The log says 'apache2' failed to start. What am I doing wrong? EDIT As suggested in the comments, I ran monit in verbose mode, by monit -vv monitor apache2 (the exact command suggested in the comments failed). The output is Runtime constants: Control file = /etc/monit/monitrc Log file = /var/log/monit.log Pid file = /var/run/monit.pid Debug = True Log = True Use syslog = False Is Daemon = True Use process engine = True Poll time = 60 seconds with start delay 0 seconds Expect buffer = 256 bytes Event queue = base directory /var/lib/monit/events with 100 slots Mail from = (not defined) Mail subject = (not defined) Mail message = (not defined) Start monit httpd = True httpd bind address = Any/All httpd portnumber = 2812 httpd signature = True Use ssl encryption = False httpd auth. style = Basic Authentication The service list contains the following entries: Process Name = apache2 Pid file = /usr/local/apache/logs/apache2.pid Monitoring mode = active Start program = '/etc/init.d/apache2 start' timeout 30 second(s) Stop program = '/etc/init.d/apache2 stop' timeout 30 second(s) Existence = if does not exist 1 times within 1 cycle(s) then restart else if succeeded 1 times within 1 cycle(s) then alert Pid = if changed 1 times within 1 cycle(s) then alert Ppid = if changed 1 times within 1 cycle(s) then alert Port = if failed localhost:6543 [HTTP via TCP] with timeout 5 seconds 1 times within 1 cycle(s) then exec '/usr/bin/touch /tmp/prova-monit' timeout 0 cycle(s) else if succeeded 1 times within 1 cycle(s) then alert System Name = system_andrea-Vostro-420-Series Monitoring mode = active

  • Having trouble Getting "RTSP over HTTP"

    - by Muhammad Adeel Zahid
    There is an axis camera that is connected to our site (camba.tv) through axis one click connection component (which acts as proxy). We can communicate with this camera only through http by setting the proxy to our OCCC server's address. If we want to get RTSP streams (h.264) we are only left with "RTSP over HTTP" option. For this I have followed axis VAPIX 3 documentation section 3.3. I issue requests through fiddler but don't get any response. But when i put the URL (axrtsphttp://1.00408CBEA38B/axis-media/media.amp) in windows media player (with proxy set to OCCC server 212.78.237.156:3128) the player is able to get RTSP stream over HTTP after logging in. I have created a request trace of communication between camera and windows media player through wireshark and the request that brings the stream looks like http://1.00408cbea38b/axis-media/media.amp HTTP/1.1 x-sessioncookie: 619 User-Agent: Axis AMC Host: 1.00408CBEA38B Proxy-Connection: Keep-Alive Pragma: no-cache Authorization: Digest username="root",realm="AXIS_00408CBEA38B",nonce="000a8b40Y0100409c13ac7e6cceb069289041d8feb1691",uri="/axis-media/media.amp",cnonce="9946e2582bd590418c9b70e1b17956c7",nc=00000001,response="f3cab86fc84bfe33719675848e7fdc0a",qop="auth" HTTP/1.0 200 OK Content-Type: application/x-rtsp-tunnelled Date: Tue, 02 Nov 2010 11:45:23 GMT RTSP/1.0 200 OK CSeq: 1 Content-Type: application/sdp Content-Base: rtsp://1.00408CBEA38B/axis-media/media.amp/ Date: Tue, 02 Nov 2010 11:45:23 GMT Content-Length: 410 v=0 o=- 1288698323798001 1288698323798001 IN IP4 1.00408CBEA38B s=Media Presentation e=NONE c=IN IP4 0.0.0.0 b=AS:50000 t=0 0 a=control:* a=range:npt=0.000000- m=video 0 RTP/AVP 96 b=AS:50000 a=framerate:30.0 a=transform:1,0,0;0,1,0;0,0,1 a=control:trackID=1 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1; profile-level-id=420029; sprop-parameter-sets=Z0IAKeNQFAe2AtwEBAaQeJEV,aM48gA== RTSP/1.0 200 OK CSeq: 2 Session: 3F4763D8; timeout=60 Transport: RTP/AVP/TCP;unicast;interleaved=0-1;ssrc=060922C6;mode="PLAY" Date: Tue, 02 Nov 2010 11:45:24 GMT RTSP/1.0 200 OK CSeq: 3 Session: 3F4763D8 Range: npt=0- RTP-Info: url=rtsp://1.00408CBEA38B/axis-media/media.amp/trackID=1;seq=7392;rtptime=4190934902 Date: Tue, 02 Nov 2010 11:45:24 GMT [Binary Stream Content] But when i copy this request to fiddler, I only get 200 status code with content-type set to application/x-rtsp-tunneled and there is no stream data. The only thing i do different with stream is to use Basic in authorization header instead of Digest and I do not get 401 (Un authorized) status code. Can anyone explain what's happening here? How can I write request sequences to get stream in fiddler? If it is needed, I can upload the wireshark request dump somewhere.

  • PHP: gethostbyname() suddenly no longer resolves names to IPs when run in Apache

    - by hurikhan77
    One of our older legacy servers which gets no further updates or reconfigurations suddenly stopped resolving hostnames to IPs when PHP is executed within Apache. However, it still works fine when executed from the CLI. From the RSS caches last modification time, I deduce that it stopped working on around Mar, 28th. To reproduce the problem, I created a script using fsockopen() and it said "connection failed (errno 2)". I further reduced the problem to being related with a failed name resolution: <?php $addr = gethostbyname("twitter.com"); echo "ADDR($addr)"; ?> When I run this through Apache, the output is ADDR(twitter.com), which is wrong. When I run this from the CLI, the output is ADDR(aaa.bbb.ccc.ddd) with varying IP addresses, as expected. Nothing on the server setup has changed. CLI and Apache module share the same php.ini. PHP is version v4.4.9 with Zend Optimizer v2.5.10. Apache is v1.3.31. I know the versions are old. But since nothing has been changed, a solution like "try to upgrade versions first" is no solution as the server's feature set/versioning is frozen and will be replaced soon. Still we need a solution. If I run dig through the script, it works in both environments (mod_php and CLI) but this is more than an ugly hack as it would involve many edits and testing throughout the whole script base which is also undesired as the PHP application on the server is frozen, too, and only receives security updates. It will be replaced by a complete rewrite (on the new server). But as the rewrite will take some time and successive replace parts of the legacy application, we need a fix for the resolver problem. I already googled a bit and while the problem is known, many did not find a fix. The fix to raise memory limits did not work. Restarts did not work. The resolver in mod_php just did stop working for no apparent reason. :-(

  • Persuading openldap to work with SSL on Ubuntu with cn=config

    - by Roger
    I simply cannot get this (TLS connection to openldap) to work and would appreciate some assistance. I have a working openldap server on ubuntu 10.04 LTS, it is configured to use cn=config and most of the info I can find for TLS seems to use the older slapd.conf file :-( I've been largely following the instructions here https://help.ubuntu.com/10.04/serverguide/C/openldap-server.html plus stuff I've read here and elsewhere - which of course could be part of the problem as I don't totally understand all of this yet! I have created an ssl.ldif file as follows; dn:cn=config add: olcTLSCipherSuite olcTLSCipherSuite: TLSV1+RSA:!NULL add: olcTLSCRLCheck olcTLSCRLCheck: none add: olcTLSVerifyClient olcTLSVerifyClient: never add: olcTLSCACertificateFile olcTLSCACertificateFile: /etc/ssl/certs/ldap_cacert.pem add: olcTLSCertificateFile olcTLSCertificateFile: /etc/ssl/certs/my.domain.com_slapd_cert.pem add: olcTLSCertificateKeyFile olcTLSCertificateKeyFile: /etc/ssl/private/my.domain.com_slapd_key.pem and I import it using the following command line ldapmodify -x -D cn=admin,dc=mydomain,dc=com -W -f ssl.ldif I have edited /etc/default/slapd so that it has the following services line; SLAPD_SERVICES="ldap:/// ldapi:/// ldaps:///" And everytime I'm making a change, I'm restarting slapd with /etc/init.d/slapd restart The following command line to test out the non TLS connection works fine; ldapsearch -d 9 -D cn=admin,dc=mydomain,dc=com -w mypassword \ -b dc=mydomain,dc=com -H "ldap://mydomain.com" "cn=roger*" But when I switch to ldaps using this command line; ldapsearch -d 9 -D cn=admin,dc=mydomain,dc=com -w mypassword \ -b dc=mydomain,dc=com -H "ldaps://mydomain.com" "cn=roger*" This is what I get; ldap_url_parse_ext(ldaps://mydomain.com) ldap_create ldap_url_parse_ext(ldaps://mydomain.com:636/??base) ldap_sasl_bind ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP mydomain.com:636 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying 127.0.0.1:636 ldap_pvt_connect: fd: 3 tm: -1 async: 0 TLS: can't connect: A TLS packet with unexpected length was received.. ldap_err2string ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) Now if I check netstat -al I can see; tcp 0 0 *:www *:* LISTEN tcp 0 0 *:ssh *:* LISTEN tcp 0 0 *:https *:* LISTEN tcp 0 0 *:ldaps *:* LISTEN tcp 0 0 *:ldap *:* LISTEN I'm not sure if this is significant as well ... I suspect it is; openssl s_client -connect mydomain.com:636 -showcerts CONNECTED(00000003) 916:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:188: I think I've made all my certificates etc OK and here are the results of some checks; If I do this; certtool -e --infile /etc/ssl/certs/ldap_cacert.pem I get Chain verification output: Verified. certtool -e --infile /etc/ssl/certs/mydomain.com_slapd_cert.pem Gives "certtool: the last certificate is not self signed" but it otherwise seems OK? Where have I gone wrong? Surely getting openldap to run securely on ubuntu should be easy and not require a degree in rocket science! Any ideas?

  • Making sense of S.M.A.R.T

    - by James
    First of all, I think everyone knows that hard drives fail a lot more than the manufacturers would like to admit. Google did a study that indicates that certain raw data attributes that the S.M.A.R.T status of hard drives reports can have a strong correlation with the future failure of the drive. We find, for example, that after their first scan error, drives are 39 times more likely to fail within 60 days than drives with no such errors. First errors in re- allocations, offline reallocations, and probational counts are also strongly correlated to higher failure probabil- ities. Despite those strong correlations, we find that failure prediction models based on SMART parameters alone are likely to be severely limited in their prediction accuracy, given that a large fraction of our failed drives have shown no SMART error signals whatsoever. Seagate seems like it is trying to obscure this information about their drives by claiming that only their software can accurately determine the accurate status of their drive and by the way their software will not tell you the raw data values for the S.M.A.R.T attributes. Western digital has made no such claim to my knowledge but their status reporting tool does not appear to report raw data values either. I've been using HDtune and smartctl from smartmontools in order to gather the raw data values for each attribute. I've found that indeed... I am comparing apples to oranges when it comes to certain attributes. I've found for example that most Seagate drives will report that they have many millions of read errors while western digital 99% of the time shows 0 for read errors. I've also found that Seagate will report many millions of seek errors while Western Digital always seems to report 0. Now for my question. How do I normalize this data? Is Seagate producing millions of errors while Western digital is producing none? Wikipedia's article on S.M.A.R.T status says that manufacturers have different ways of reporting this data. Here is my hypothesis: I think I found a way to normalize (is that the right term?) the data. Seagate drives have an additional attribute that Western Digital drives do not have (Hardware ECC Recovered). When you subtract the Read error count from the ECC Recovered count, you'll probably end up with 0. This seems to be equivalent to Western Digitals reported "Read Error" count. This means that Western Digital only reports read errors that it cannot correct while Seagate counts up all read errors and tells you how many of those it was able to fix. I had a Seagate drive where the ECC Recovered count was less than the Read error count and I noticed that many of my files were becoming corrupt. This is how I came up with my hypothesis. The millions of seek errors that Seagate produces are still a mystery to me. Please confirm or correct my hypothesis if you have additional information. Here is the smart status of my western digital drive just so you can see what I'm talking about: james@ubuntu:~$ sudo smartctl -a /dev/sda smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: WDC WD1001FALS-00E3A0 Serial Number: WD-WCATR0258512 Firmware Version: 05.01D05 User Capacity: 1,000,204,886,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Thu Jun 10 19:52:28 2010 PDT SMART support is: Available - device has SMART capability.

  • Active Directory Time Synchronisation - Time-Service Event ID 50

    - by George
    I have an Active Directory domain with two DCs. The first DC in the forest/domain is Server 2012, the second is 2008 R2. The first DC holds the PDC Emulator role. I sporadically receive a warning from the Time-Service source, event ID 50: The time service detected a time difference of greater than %1 milliseconds for %2 seconds. The time difference might be caused by synchronization with low-accuracy time sources or by suboptimal network conditions. The time service is no longer synchronized and cannot provide the time to other clients or update the system clock. When a valid time stamp is received from a time service provider, the time service will correct itself. Time sync in the domain is configured with the second DC to synchronise using the /syncfromflags:DOMHIER flag. The first DC is configured to sync time using a /syncfromflags:MANUAL /reliable:YES, from a peerlist consisting of a number of UK based stratum 2 servers, such as ntp2d.mcc.ac.uk. I'm confused why I receive this event warning. It implies that my PDC emulator cannot synchronise time with a supposedly reliable external time source, and it quotes a time difference of 5 seconds for 900 seconds. It's worth also mentioning that I used to use a UK pool from ntp.org but I would receive the warning much more often. Since updating to a number of UK based academic time servers, it seems to be more reliable. Can someone with more experience shed some light on this - perhaps it is purely transient? Should I disregard the warning? Is my configuration sound? EDIT: I should add that the DCs are virtual, and installed on two separate VMware ESXi/vSphere physical hosts. I can also confirm that as per MDMarra's comment and best practice, VMware timesync is disabled, since: c:\Program Files\VMware\VMware Tools\VMwareToolboxCmd.exe timesync status returns Disabled. EDIT 2 Some strange new issue has cropped up. I've noticed a pattern. Originally, the event ID 50 warnings would occur at about 1230pm each day. This is interesting since our veeam backup happens at 12 midday. Since I made the changes discussed here, I now receive an event ID 51 instead of 50. The new warning says that: The time sample received from peer server.ac.uk differs from the local time by -40 seconds (Or approximately 40 seconds). This has happened two days in a row. Now I'm even more confused. Obviously the time never updates until I manually intervene. The issue seems to be related to virtualisation and veeam. Something may be occuring when veeam is backing up the PDCe. Any suggestions? UPDATE & SUMMARY msemack's excellent list of resources below (the accepted answer) provided enough information to correctly configure the time service in the domain. This should be the first port of call for any future people looking to verify their configuration. The final "40 second jump" issue I have resolved (there are no more warnings) through adjusting the VMware time sync settings as noted in the veeam knowledge base article here: http://www.veeam.com/kb1202 In any case, should any future reader use ESXi, veeam or not, the resources here are an excellent source of information on the time sync topic and msemack's answer is particularly invaluable.

  • apache2 namevirtualhost resolving wrong site

    - by joe
    Running apache 2.2.6. I'm setting up a development environment. dev and production will be hosted on the same machine, same IP address. DNS entries like prod.domain.com and dev.domain.com point to the same IP. * Imprortant: it is required that dev and prod are otherwise completely separate. Each will run it's own apache instance. Each will use it's own apache configuration. Each, prod and dev, will host http and https. I have this set up and working, but not as restrictive as I'd like. For instance, the production config: NameVirtualHost *:80 NameVirtualHost *:443 <VirtualHost *:80 > ServerName prod.domain.com # ... etc </VirtualHost> <VirtualHost *:443 > ServerName prod.domain.com # ... etc </VirtualHost> The dev site is set up similarly, using ports 8080 and 4443. Each site works fine. But assuming both apaches are running, one can also hit "cross-site" by mistake. So, inadvertently hitting prod.domain.com:8080 successfully returns a page from the dev site. It would be much better if this failed completely. This is a bit more difficult to solve (for me) because of the need for two apache configs. If all in one, the single process would have full knowledge of everything. So, I tried to solve this with brute force, including virtual hosts for the "other" site, with something that would fail, like no access to documentroot. But apache then inexplicably finds the "wrong" virtual host. Here's the full config for production, with the dummy dev configs. NameVirtualHost *:80 NameVirtualHost *:443 # ---------------------------------------------- # DUMMY HOSTS <VirtualHost *:8080 > ServerName dev.domain.com:8080 DocumentRoot /tmp/ <Directory /tmp/ > Order deny,allow Deny from all </Directory> </VirtualHost> <VirtualHost *:4443 > ServerName dev.domain.com:4443 DocumentRoot /tmp/ <Directory /tmp/ > Order deny,allow Deny from all </Directory> </VirtualHost> # ---------------------------------------------- # REAL PRODUCTION HOSTS <VirtualHost *:80 > ServerName prod.domain.com:80 DocumentRoot /something/valid/ <Directory /something/valid/> Order allow,deny Allow from all </Directory> </VirtualHost> <VirtualHost *:443 > ServerName prod.domain.com:443 DocumentRoot /something/valid/ <Directory /something/valid/> Order allow,deny Allow from all </Directory> # .... other valid ssl setup </VirtualHost> Here's the strange thing. With this configuration, a prod.domain.com:80 hit succeeds. But a prod.domain.com:443 hit fails, because it finds the dev.domain.com:4443 instead. I've also tried removing the port from the ServerName, but it still doesn't work. Sorry for the long question. Hopefully this is enough information. Thanks in advance for any help.

  • Can't get Apache 2.2.21 to compile with OpenSSL support

    - by angstwad
    Alright -- having a bad couple days here compiling Apache 2.2.21 on CentOS 5.7 with the following configure commands: ./configure --enable-ssl=shared --with-ssl=/usr/local/openssl I've compiled from source OpenSSL 1.0.0e from source: ./config --prefix=/usr/local --openssldir=/usr/local/openssl shared zlib-dynamic I attempt to start Apache and it returns: httpd: Syntax error on line 54 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/mod_ssl.so into server: /usr/local/apache2/modules/mod_ssl.so: undefined symbol: SSL_get_servername If I look at how the libraries are linked, this is what I get: [root@web1 modules]# ldd mod_ssl.so libssl.so.6 => /lib64/libssl.so.6 (0x00002aaaaace4000) libcrypto.so.6 => /lib64/libcrypto.so.6 (0x00002aaaaaf30000) libdl.so.2 => /lib64/libdl.so.2 (0x00002aaaab281000) libz.so.1 => /lib64/libz.so.1 (0x00002aaaab486000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00002aaaab69a000) libc.so.6 => /lib64/libc.so.6 (0x00002aaaab8b5000) libgssapi_krb5.so.2 => /usr/lib64/libgssapi_krb5.so.2 (0x00002aaaabc0e000) libkrb5.so.3 => /usr/lib64/libkrb5.so.3 (0x00002aaaabe3c000) libcom_err.so.2 => /lib64/libcom_err.so.2 (0x00002aaaac0d1000) libk5crypto.so.3 => /usr/lib64/libk5crypto.so.3 (0x00002aaaac2d4000) /lib64/ld-linux-x86-64.so.2 (0x0000555555554000) libkrb5support.so.0 => /usr/lib64/libkrb5support.so.0 (0x00002aaaac4f9000) libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x00002aaaac702000) libresolv.so.2 => /lib64/libresolv.so.2 (0x00002aaaac904000) libselinux.so.1 => /lib64/libselinux.so.1 (0x00002aaaacb19000) libsepol.so.1 => /lib64/libsepol.so.1 (0x00002aaaacd32000) Basically, I've tired compiling from source OpenSSL (both 0.9.8r and 1e), having yum reinstall from the repos, done a make clean and remade both OpenSSL and Apache numerous times -- but I can't get it to compile into the apache base or dynamically as a shared object file. What am I doing wrong here? Update 1: After doing a make clean and make distclean, I've reconfigured with the same parameters as above without any effect. The config.log is at Pastebin. Update 2: Modifying the LD_LIBRARY_PATH had no effect on the lib-deps of mod_ssl.so. UPDATE 3: I've compiled and recompiled many times, and verified with ldconfig that the OpenSSL libs dir is in my path, and included in ld.so.conf. Still cannot get httpd/mod_ssl to load the library at runtime.

  • Adding a Microsoft Exchange 2010 account to my Windows Phone 7.5 mobile (Nokia Lumia 800) without trusted certificate

    - by MAXE
    I have problems in creating an account on my Nokia Lumia 800 (OS version: 7.10.8773.98, of course with Windows Phone 7.1 mounted with all updates) to one of my company's Microsoft Exchange 2010 server, because it cannot provide a trusted certificate...but only when contacting it from outside my network (like https ://mail.(CompanyName).com). Accessing the server from inside my network (pointing directly to the machine name or internal IP address: https ://(MachineName) or https ://10.0.1.200) gives me NO PROBLEM AT ALL! Setting correctly (I guess) all the parameters for the account (accessing from outside my network), the connection (after correctly set my credentials as asked) will not be established. It gives the next error (translated from my language manually): Error of <CompanyName> There is a problem with the certificate of (Server Address). Please contact support or the provider. Last try: X minutes ago Error code: 80072F06 I've tried all possible configurations and parameters (including the check The server requires an encrypted (SSL) connection, of course), but no way. EDITED: As suggested by Oliver Salzburg, I also tried this way without any results. I tried so: I went to my OWA (Outlook Web Access) that gives me the same problem (problems the certificate, it's not trusted) After accepting to continue, I clicked on the Error in Certificate button of the Internet Explorer 9 address bar - Show Certificates - page Details, show: - Copy to file... button - in the exporting wizard: Next - Binary encoding DER X.509 (.cer) (but there was also Base binary 64 X.509 (.cer), no way) - Next - saved to a new file From my Google Mail Account, I sent a mail to myself the certificate as attachment I read the mail from my WP7 phone, saved the attachment and then ran it: answering Yes to Do you wany to install the certificate? of course... Closed any active program and rebooted the phone Re-tried in synchronizing my account....:(...SAME PROBLEM! EDITED 2: Thanks again to Oliver Salzburg, I tried the next solution: I went to the site https://www.testexchangeconnectivity.com/ I selected Exchange ActiveSync option, as suggested I setted all my parameters, as I made for my phone I also setted the option Ignore SSL attendibility (and in another test I didn't) I performed my test This is the complete log (I removed my parameters): Seems the same problem (machine name in the certificate is different from the external Exchange website domain name?)! It is possible to get rid of this annoying (I know by myself who is this server!) problem? Thank you very much.

  • How to configure DNS so that www.example.com goes to one server, *.example.com to another

    - by fishwebby
    I'm trying to set up my domain as follows, but I'm not actually sure if it's possible. I have a domain where I would like the base and www addresses to go to my static site, but others to go to my application server. For example: My domain is registered with Dreamhost, and my application is on a VPS at Webbynode. I've set up the domain in Dreamhost to use Webbynode's nameservers: ns1.dnswebby.com ns2.dnswebby.com ns3.dnswebby.com And in Webbynode I've set up a wildcard A record to point to the IP address of my VPS: * 1.2.3.4 A and this works nicely, if I go to app.example.com it resolves to my application server at Webbynode. However, what I'd like to do is have example.com and www.example.com go to my static site, hosted back at Dreamhost, whilst still having any other domain go to my app. What I've done to try and achieve this is set up these DNS "NS" entries at Webbynode, trying to get Dreamhost to resolve these domain names: (empty) ns1.dreamhost.com NS (empty) ns2.dreamhost.com NS (empty) ns3.dreamhost.com NS www ns1.dreamhost.com NS www ns2.dreamhost.com NS www ns3.dreamhost.com NS (I don't have a fixed IP address at Dreamhost so I can't just set up simple A records). However this doesn't work... does anyone have any idea if this is possible and if so how it could be done? Update: I've got this working now, as above for the domain (i.e. registered with Dreamhost, but using Webbynode's nameservers). To delegate the DNS for www.example.com to Dreamhost, I've got the following DNS entries set up: www.example.com. ns1.dreamhost.com. NS www.example.com. ns2.dreamhost.com. NS www.example.com. ns3.dreamhost.com. NS (note the full stops at the end) And to get example.com to resolve to my static site, I set up CNAME record: example.com. www.example.com. CNAME So now, example.com and www.example.com go to my static site on Dreamhost, and if they change the IP address of my shared hosting it won't affect me, and all other subdomains go to my application server. This seems to work nicely, but if anyone knows a better way to do it I'd be happy to hear it. Thanks to all who replied.

  • samba 3.5 "force user" doesn't seem to be sticking

    - by myCubeIsMyCell
    After installing a new OS with newer version of samba, I'm having trouble accessing my shares. I can browse to the specific share, but only to the top level. As best I can tell from the logs, it seems the "force user" in the samba config isn't sticking beyond the initial connection. Details below. I installed a new version of CentOS on my storage server. My old CentOS (4?)install had samba version 3.0.33, new CentOS is using 3.5.10. No domain/AD involved ... just home workgroup. no real security... just some shares hidden & some defined as read-only. here's my config: [global] workgroup = WORKGROUP server string = Samba Server Version %v netbios name = luna security = share # logs split per machine log file = /var/log/samba/log.%m log level = 2 # max 50KB per log file, then rotate max log size = 50 winbind use default domain = Yes [strge] comment = please path = /storage browseable = yes read only = no force user = windowsguest force group = users guest ok = yes So... the problem I'm running into is that the 'force user' only seems to hold for the initial connection & I see all the top level folders fine. When I drill into a folder I get access denied - which appears to be due to my windows user info being sent (trys to authenticate xuser - a non-existant user to samba, so maps to nobody & fails). Here's the smb error msg: [2012/11/29 14:30:27.326195, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [xuser] -> [xuser] FAILED with error NT_STATUS_NO_SUCH_USER [2012/11/29 14:30:27.326251, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [nobody] -> [nobody] FAILED with error NT_STATUS_NO_SUCH_USER Most of the top level directories are 755, some 777. Either way, can not access them. If I do a chown -R windowsguest.users ... no change... but if I do a chmod -R to 777 or 755 they become browsable... but still can't create files (even for 777 ones). Not sure what role it plays if any... but had to recreate the user windowsguest under the new os install, uid & gid match old user. Seems the main issue as far as I can tell is that samba isn't maintaining the 'force user' - but I could be wildly off base. Client OS is win7 pro x64. Thanks for any suggestions or advice!

  • Connecting to localhost resolves 127.0.0.1 but connects with external IP [Linux, Debian]

    - by skgsergio
    I'm having a problem with a dedicated server, I don't known if it's the default behavior but this is the problem: If I connect to a service located on the server with localhost the service gets as source IP the external IP. Let me show an example, I use netcat for listening on 127.0.0.1:4444 xxxxxx # nc -vv -l -s 127.0.0.1 -p 4444 listening on [127.0.0.1] 4444 ... Lets check if it's ok: xxxxxx ~ # netstat -atnp | grep 4444 tcp 0 0 127.0.0.1:4444 0.0.0.0:* LISTEN 14038/nc Ok lets connect: xxxxxx ~ # nc -vv 127.0.0.1 4444 localhost [127.0.0.1] 4444 (?) open Return to the tty that have the listening process and I get this: connect to [127.0.0.1] from xxxxxx.net [176.31.xxx.xx] 50354 So that's the problem. I have a server daemon that have to listen on localhost and checks that the ip is 127.0.0.1 when the client connects but for some reason when I connect to localhost it reports the external ip... If I do the same with IPv6 it works as excepted... Detects connection as localhost (::1). Some info that can be useful: "localhost" resolves without problems to 127.0.0.1 xxxxxx ~ # ping -c1 localhost PING localhost (127.0.0.1) 56(84) bytes of data. 64 bytes from localhost (127.0.0.1): icmp_req=1 ttl=64 time=0.086 ms Nothing weird on my hosts file, I think... xxxxxx ~ # grep -v ^# /etc/hosts 127.0.0.1 localhost localhost.localdomain 176.31.xxx.xx xxxxxx.net ns1.xxxxxx.net ::1 ip6-localhost ip6-loopback feo0::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts And ifconfig reports all ok... eth0 Link encap:Ethernet HWaddr e0:69:95:d8:30:a1 inet addr:176.31.xxx.xx Bcast:176.31.108.255 Mask:255.255.255.0 inet6 addr: 2001:41d0:8:xxxx::/64 Scope:Global inet6 addr: 2001:41d0:8:xxxx:x:xx:xx:xx/64 Scope:Global inet6 addr: fe80::e269:95ff:fed8:30a1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:16916 errors:0 dropped:0 overruns:0 frame:0 TX packets:16914 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8410679 (8.0 MiB) TX bytes:10539881 (10.0 MiB) Interrupt:28 Base address:0xe000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:5570 errors:0 dropped:0 overruns:0 frame:0 TX packets:5570 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:744490 (727.0 KiB) TX bytes:744490 (727.0 KiB)

  • Why do we need different CPU architecture for server & mini/mainframe & mixed-core?

    - by claws
    Hello, I was just wondering what other CPU architectures are available other than INTEL & AMD. So, found List of CPU architectures on Wikipedia. It categorizes notable CPU architectures into following categories. Embedded CPU architectures Microcomputer CPU architectures Workstation/Server CPU architectures Mini/Mainframe CPU architectures Mixed core CPU architectures I was analyzing the purposes and have few doubts. I taking Microcomputer CPU (PC) architecture as reference and comparing others. Embedded CPU architecture: They are a completely new world. Embedded systems are small & do very specific task mostly real time & low power consuming so we do not need so many & such wide registers available in a microcomputer CPU (typical PC). In other words we do need a new small & tiny architecture. Hence new architecture & new instruction RISC. The above point also clarifies why do we need a separate operating system (RTOS). Workstation/Server CPU architectures I don't know what is a workstation. Someone clarify regarding the workstation. As of the server. It is dedicated to run a specific software (server software like httpd, mysql etc.). Even if other processes run we need to give server process priority therefore there is a need for new scheduling scheme and thus we need operating system different than general purpose one. If you have any more points for the need of server OS please mention. But I don't get why do we need a new CPU Architecture. Why cant Microcomputer CPU architecture do the job. Can someone please clarify? Mini/Mainframe CPU architectures Again I don't know what are these & what miniframes or mainframes used for? I just know they are very big and occupy complete floor. But I never read about some real world problems they are trying to solve. If any one working on one of these. Share your knowledge. Can some one clarify its purpose & why is it that microcomputer CPU archicture not suitable for it? Is there a new kind of operating system for this too? Why? Mixed core CPU architectures Never heard of these. If possible please keep your answer in this format: XYZ CPU architectures Purpose of XYZ Need for a new architecture. why can't current microcomputer CPU architecture work? They go upto 3GHZ & have upto 8 cores. Need for a new Operating System Why do we need a new kind of operating system for this kind of archictures?

  • LDAP installed, running, but can't connect remotely [Ubuntu 10.10]

    - by Casey Jordan
    Hi all, I installed LDAP on my ubuntu 10.10 system, using the tutorial found here: https://help.ubuntu.com/10.10/serverguide/C/openldap-server.html Everything seems to be working well, when logged into the server via ssh I can run commands like: > ldapsearch -xLLL -b "dc=easydita,dc=com" uid=john sn givenName cn dn: uid=john,ou=people,dc=easydita,dc=com sn: Doe givenName: John cn: John Doe So I think that's a good sign that things are working well.

  • Ubuntu 12 crashed and took down network

    - by Leopd
    We recently set up a new Ubuntu 12.04LTS server on our network. It's not fully configured so it's not doing much beyond sshd and a default apache2 install. But this evening it appears to have crashed. It wasn't responding to the network or the keyboard. But the worst part is, it took down the entire network. My knowledge of the network stack below OSI layer 3 is very limited, so the rest confuses me. When this machine was physically connected to the network, no other machine could connect to the outside internet. When things were broken, running arp showed that our gateway's IP address (10.0.1.1) was listed as "invalid." Unplugging the server from the network fixed the problem, and plugging it back in broke it again. So the crashed server was advertising itself as owning the gateway's IP address? There's nothing at all in syslog during the time when it was causing problems. Any ideas about how to figure out what went wrong or what we can do to prevent it from happening again? I'm hesitant to even put the machine back on the network right now. Update ** It crashed again, and I ran tcpdump -penn arp (thanks bahamat!) for several minutes and got this... (timestamps and duplicate lines removed) 00:1e:65:f8:dc:24 > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: Request who-has 10.0.1.1 tell 10.0.2.191, length 46 00:1e:65:f8:dc:24 > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: Request who-has 10.0.1.44 tell 10.0.2.191, length 46 60:d8:19:d4:71:d6 > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: Request who-has 10.0.1.1 tell 10.0.2.125, length 46 d4:9a:20:04:e9:78 > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 42: Request who-has 192.168.1.1 tell 192.168.1.100, length 28 Update 2 ** When the network is functioning properly, arping -c4 10.0.1.1 returns this: ARPING 10.0.1.1 60 bytes from c0:c1:c0:77:25:8e (10.0.1.1): index=0 time=267.982 usec 60 bytes from c0:c1:c0:77:25:8e (10.0.1.1): index=1 time=422.955 usec 60 bytes from c0:c1:c0:77:25:8e (10.0.1.1): index=2 time=299.215 usec 60 bytes from c0:c1:c0:77:25:8e (10.0.1.1): index=3 time=366.926 usec --- 10.0.1.1 statistics --- 4 packets transmitted, 4 packets received, 0% unanswered (0 extra) When the bad server is plugged in, arping -c4 10.0.1.1 returns: ARPING 10.0.1.1 --- 10.0.1.1 statistics --- 4 packets transmitted, 0 packets received, 100% unanswered (0 extra) Context ** 10.0.x.x is the main subnet. 10.0.1.1 is the main internet gateway 10.0.1.44 is a printer 10.0.2.* devices are all laptops / workstations I have no idea what's using the 192.168.x.x subnet -- your guesses are at least as good as mine. A VM on a workstation? A misconfigured WAP? Somebody re-sharing wifi? A machine that failed to DHCP? The offending ubuntu server's MAC address ends in cd:80 so isn't listed in the dump. It should DHCP to 10.0.3.3 Thanks for any help. This ARP stuff is all voodoo to me. Packets just go to IP addresses, right? ;)

  • Ubuntu unattended-upgrades stops apache

    - by Robbie
    This morning i was alerted to the fact that both apache instances serving my app were not responding to requests from my load balancer. I attempted apachectl restart and it said apache was not running. So, i started apache on both instances and got the service up again. I then followed the logs and worked out that both had performed upgrades via the unattended-upgrades package moments before they stopped responding. /var/log/unattended-upgrades/unattended-upgrades.log 2013-07-02 06:30:51,875 INFO Starting unattended upgrades script 2013-07-02 06:30:51,875 INFO Allowed origins are: ['o=Ubuntu,a=precise-security'] 2013-07-02 06:33:57,771 INFO Packages that are upgraded: accountsservice apache2 apache2-mpm-prefork apache2-utils apache2.2-bin apache2.2-common apparmor apport apt apt-transport-https apt-utils bind9-host binutils dbus dnsutils gnupg gpgv isc-dhcp-client isc-dhcp-common krb5-locales libaccountsservice0 libapt-inst1.4 libapt-pkg4.12 libbind9-80 libc-bin libc-dev-bin libc6 libc6-dev libcurl3-gnutls libdbus-1-3 libdbus-glib-1-2 libdns81 libdrm-intel1 libdrm-nouveau1a libdrm-radeon1 libdrm2 libexpat1 libfreetype6 libgc1c2 libgnutls-dev libgnutls-openssl27 libgnutls26 libgnutlsxx27 libisc83 libisccc80 libisccfg82 liblwres80 libruby1.8 libx11-6 libx11-data libxcb1 libxext6 libxml2 linux-firmware linux-image-virtual linux-libc-dev linux-virtual multiarch-support openssl perl perl-base perl-modules python-apport python-crypto python-keyring python-problem-report python-software-properties ri1.8 ruby1.8 ruby1.8-dev sudo tzdata update-manager-core 2013-07-02 06:33:57,772 INFO Writing dpkg log to '/var/log/unattended-upgrades/unattended-upgrades-dpkg_2013-07-02_06:33:57.772399.log' 2013-07-02 06:36:10,584 INFO All upgrades installed I'm running Ubuntu 12.04 on Amazon EC2 servers.

  • Vagrant reporting VirtualBox guest additions out of date

    - by DTest
    Fairly new to Vagrant, so bear with me if I don't understand the process. I downloaded a CentOS box off http://www.vagrantbox.es/ Started it up running VirtualBox 4.2.4 and got this message: [default] The guest additions on this VM do not match the install version of VirtualBox! This may cause things such as forwarded ports, shared folders, and more to not work properly. If any of those things fail on this machine, please update the guest additions and repackage the box. Guest Additions Version: 4.0.8 VirtualBox Version: 4.2.4 So I used the vbguest plugin to update the guest additions, then repackaged the box as suggested. Having replaced the old box and loading it up I get the same message about guest additions being outdated, but vbguest reports that they are up to date (the automatic vbguest update is disabled in my Vagrantfile): Vagrant::Config.run do |config| config.vm.box = "centos56_64" config.vbguest.auto_update = false config.vbguest.no_remote = true end And the commands: dtest$ vagrant up [default] Importing base box 'centos56_64'...
