• Can a named (bind) crash make a server unreachable?

  - by giorgio79

  My server recently became unreachable, and after restart a named error was the last line I found in /var/log/messages before restart: Jun 26 00:15:06 host named[1303]: error (network unreachable) resolving 'dlv.isc.org/DNSKEY/IN': 2001:500:71::29#53 Jun 26 06:38:55 host kernel: imklog 5.8.10, log source = /proc/kmsg started. Jun 26 06:38:55 host rsyslogd: [origin software="rsyslogd" swVersion="5.8.10" x-pid="1294" x-info="http://www.rsyslog.com"] start Jun 26 06:38:55 host kernel: Initializing cgroup subsys cpuset Can a named crash make a server unreachable? I doubt it, as I assume I should still be able to login with ssh via IP, but the server did not respond...So, I am trying to make heavy guesses here.

• nginx redirect what is not coming from load balancing

  - by dawez

  I have nginx on SERVER1 that is acting as load balancing between SERVER1 and SERVER2 in SERVER1 I have the upstreams for the load balancing defined as : upstream de.server.com { # similar upstreams defined also for other languages # SELF SERVER1 server 127.0.0.1:8082 weight=3 max_fails=3 fail_timeout=2; # other SERVER2 server otherserverip:8082 max_fails=3 fail_timeout=2; } The load balancing config on SERVER1 is this one: server { listen 80; server_name ~^(?<LANG>de|es|fr)\.server\.com; location / { proxy_pass http://$LANG.server.com; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # trying to pass a variable in the header to SERVER2 proxy_set_header Is-From-Load-Balancer 1; } } Then in server 2 I have: server { listen 8082; server_name localhost; root /var/www/server.com/public; # test output values add_header testloadbalancer $http_is_from_load_balancer; add_header testloadbalancer2 not_load_bal; ## other stuff here to process the request } I can see the "testloadbalancer" in the response header is set to 1 when the request is coming from the load balancing, it is not present when from a direct access: SERVER2:8082 . I would like to bounce back to the SERVER1 all the direct requests that are sent to SERVER2, but keep the ones from the load balancing. So this should forbid direct access to SERVER2:8082 and redirect to SERVER1:80 .

• Slow network interaction between 2 kvm host machines

  - by VirtualNoob

  We have 2 physical machines, Host1 is a CentOS 6.4 kvm host and hosts ~7 kvm VMs all running Ubuntu 12.04 - all of this runs perfectly. Recently we've added a 2nd host system, host2, again a CentOS 6.4 kvm host with a view to running another couple of VMs and providing some failover against host1 should it be required. Both physical machines reside in the same cabinet in our DC, and are on the same subnet - let's say host1: 1.1.1.64 and host2: 1.1.1.81. Both have their gateway set to the DC gateway of 1.1.1.254 with no hardware firewall in between. On each machine, I have 4 NICs that are bonded together to form a single interface, which is then bridged to allow the VMs to access the network. All of the VMs are online, and all of them can successfully ssh into the hosts without any delay. Both systems can access the internet fine, and I can ssh into both systems from home without any issues. However, there is a real delay when attempting to ssh from host1 to host2 (or vice versa) and this obviously means that any action required on host2, that is controlled by host1 either takes forever or results in failure due to timeout. In the interest of keeping this post short, I've put my ifcfg files into a pastie: http://pastie.org/8081648 I've tried both adding a firewall rule in each machine for the other, and also disabling the firewall entirely, so that can't be the issue. I've tried troubleshooting this myself but can't seem to get to the bottom of it. Any help or advice would be appreciated. Thanks in advance.

• Detecting Request that uses invalid Encoding using Modsecurity

  - by Ali Ahmad

  I am trying write a virtual patch using modsecurity for my hosted web application using following rule i.e. <Location /index.php> SecDefaultAction phase:2,t:none,log,deny # Validate parameter names SecRule ARGS_NAMES "!^(articleid)$" \ "msg:'Unknown parameter: %{MATCHED_VAR_NAME}'" # Expecting articleid only once SecRule &ARGS:articleid "!@eq 1" \ "msg:'Parameter articleid seen more than once'" # Validate parameter articleid SecRule ARGS:articleid "!^[0-9]{1,10}$" \ "msg:'Invalid parameter articleid'" </Location> The problem is how can i reject requests that use invalid encoding as a global WAF configuration so that this patch cannot be circumvented.

• Windows 2012 remote access can't connect

  - by Gelo Volro

  I have installed Windows Server 2012 for about 9 months ago. Earlier I could connect to my server with an external IP perfectly, but the license for the remote desktop services has ended. First, I thought it was the reason, why I couldn't use my server as RDP-server, to which users may connect. But, than in web I read, that it's possible to use windows native features, just to remove the RDP services, which are trial and the server will work as RDP-server, but with some limitations ( for e.g. such free RDP service may accept only 1 connection and other connection will be disconnected etc ). Is it true, that it's possible? If yes, please give a piece of advice, how should I repair it. Because I don't want to use TightVNC or other stuff. Thanks!

• Where does Rundesk execute local tasks from

  - by Leon Stafford

  I'm trying to interact with the nodejs Azure sdk from a CentOS installation of Rundeck. If I try from the "run" adhoc virtual shell, I am able to after running azure account import <mykey> and can then also execute other Azure commands inside of jobs if I set them as Rundeck node tasks and not selecting "dispatch to nodes" in the job settings. Trying to run the Azure sdk commands as commands to be dispatched to the node (local) fails with the error: localhost1-NodeDispatch-localexec 04:53:04 /usr/bin/env: node: No such file or directory 04:53:04 Failed: NonZeroResultCode: Result code was 127 I am not able to "jumpstart" the same environment by running azure account import <mykey> I am assuming this is a permissions/environmental issue, though not sure how to fix it. UPDATE: Executing whoami from the same job returns rundeck, so I assume I will need to either modify that to execute tasks as my system user or grant permissions to get the rundeck user into the node environment the Azure sdk is running in?

• BIND: forward 1st level zone

  - by raven

  First of all: sorry for the language, English is not my primary language. I have star-like DNS structure with many filials (more that 2): ^ | v filialNS_1.filial_1.city.local <---- ns.main.city.local <---- filialNS_2.filial_2.city.local ^ | v ns.mail.city.local is slave of all filials zones filialNS_1 is master of filial_1.city.local filialNS_2 is master of filial_2.city.local filialNS_N is master of filial_N.city.local I want to: serve DNS queries for xxx.filial_N.city.local with filialNS_N.filial_N.city.local forward all queries for xxx.xxx.xxx.local from filialNS_N to ns.main.city.local forward other queries to our provider's DNS on filial (or google-public-dns or anything else) FILIAL CONFIG named.conf zone "filial_1.city.local" { type master; file "/etc/namedb/dynamic/filial_1.city.local"; allow-update { key DHCP_UPDATER; }; allow-transfer { <ns.main.city.local IP address> }; }; zone "2.76.10.in-addr.arpa" { type master; file "/etc/namedb/dynamic/2.76.10.in-addr.arpa"; allow-update { key DHCP_UPDATER; }; allow-transfer { <ns.main.city.local IP address> }; }; zone "local." { type forward; forward only; forwarders { <ns.main.city.local IP address> }; }; nslookup server.filial_1.city.local - works fine nslookup server.main.city.local Server: 127.0.0.1 Address: 127.0.0.1#53 ** server can't find server.main.city.local: NXDOMAIN Where am I going wrong?

• missing files after reassemble of RAID-5

  - by Kris_R

  I had to open my file-server's housing on Sunday to replace a faulty fan. What I didn't see was that one of the sata-cables was not properly connected. The 1st thing I did after a reboot was a check of the RAID status and it showed immediately that one drive is missing. Till this moment the device was not used (however it was mounted, so I'm not 100% sure that system did nothing). I stopped md0 and re-plugged the cable: mdadm --stop /dev/md0 poweroff After another reboot I checked the removed drive: mdadm --examine /dev/sdd1 ... Checksum : 3276bc1d - correct Events : 315782 Layout : left-symmetric Chunk Size : 32K Number Major Minor RaidDevice State this 0 8 49 0 active sync /dev/sdd1 0 0 8 49 0 active sync /dev/sdd1 1 1 8 65 1 active sync /dev/sde1 2 2 8 33 2 active sync /dev/sdc1 3 3 8 17 3 active sync /dev/sdb1 I was a bit surprised that it was shown as active (even if earlier mdadm said, that this device was removed from array) and its checksum was OK. I recreated RAID with: mdadm --assemble /dev/md0 --scan The command mdadm --detail /dev/md0 showed that all drives were running and system was in "clean" state. I mounted the device md0 and then came hic-cup. I wanted to work on one of the last files that I had been using before all the situation and it was not there. In another place I missed actually all files from the directory where I was working. As far as I can see most of the files that are older than a few days are intact but some newer ones are missing. Now the big question: what would be your advice? Is there a way to get these data? I thought about removing the drive that was earlier labeled by mdadm and rebuild array with another empty HDD. I've found that after re-assemble the "broken" drive has another label (changed from sdd to sdb). Can this have influence on rebuilt process? If yes, how to reassemble the array properly? I'm sure the SATA-cables are connected still in the same order to the controller. p.s. Please no advises like "restore from backup". I'm doing back-ups on Sunday's night and this happened in the late afternoon, so backup is not really options for me. p.s.s. I asked this question on Unix&Linux but no answer came up during last two days. I'm getting quite anxious. Sorry for duplicating if any of you reading the other forum.

• Having two IP Routes/Gateways of last Resort on an HP Switch

  - by SteadH

  We have an HP Layer 3 Switch that is doing IP routing between vlans. The general set up is that the switch has an IP address on each VLAN and IP routing is enabled. On our servers VLAN, we have a firewall that has a connection to the outside world. To set a IP route on the HP router, we use IOS command ip route 0.0.0.0 0.0.0.0 192.168.2.1 where 192.168.2.1 is the address of our firewall, and the zeros essentially mean to route all traffic that the switch doesn't know what to do with out the firewall as a gateway. We're in the middle of an ISP and firewall change. I set up the new firewall and ran the IOS command ip route 0.0.0.0 0.0.0.0 192.168.2.254 (the address of the new firewall). Things started working nicely. When I reviewed the configuration of the switch though, I noticed that it did not replace the previous ip route command, but just added another route. Now, I know how to remove the old firewall route (no ip route 0.0.0.0 0.0.0.0 192.168.2.1), but what is the effect of having these two 0.0.0.0 routes? Is it switch implosion? Will a server just respond back over the route it receives the request from? I've read elsewhere that having two default gateways is an impossibility by definition, but I'm curious about this situation that our switch allowed. Thanks!

• Understanding RedHats recommended tuned profiles

  - by espenfjo

  We are going to roll out tuned (and numad) on ~1000 servers, the majority of them being VMware servers either on NetApp or 3Par storage. According to RedHats documentation we should choose the virtual-guestprofile. What it is doing can be seen here: tuned.conf We are changing the IO scheduler to NOOP as both VMware and the NetApp/3Par should do sufficient scheduling for us. However, after investigating a bit I am not sure why they are increasing vm.dirty_ratio and kernel.sched_min_granularity_ns. As far as I have understood increasing increasing vm.dirty_ratio to 40% will mean that for a server with 20GB ram, 8GB can be dirty at any given time unless vm.dirty_writeback_centisecsis hit first. And while flushing these 8GB all IO for the application will be blocked until the dirty pages are freed. Increasing the dirty_ratio would probably mean higher write performance at peaks as we now have a larger cache, but then again when the cache fills IO will be blocked for a considerably longer time (Several seconds). The other is why they are increasing the sched_min_granularity_ns. If I understand it correctly increasing this value will decrease the number of time slices per epoch(sched_latency_ns) meaning that running tasks will get more time to finish their work. I can understand this being a very good thing for applications with very few threads, but for eg. apache or other processes with a lot of threads would this not be counter-productive?

• Exchange 2013 Internal Relay via Smart Host

  - by Matt Clements

  Thank you for your help in advance! I am currently setting up an Exchange 2013 server, to replace our old POP3/SMTP system, however we would like to roll this out gradually when convenient for our staff. Our plan is therefore: Setup Exchange 2013 to retrieve email via POP Connector - Done Setup Exchange 2013 to send ALL mail via a SmartHost - Issues I have set the domains in Mail Flow Accepted Domains to Internal Relay, enabled a Smart Host for * as the domain name, and disabled/deleted the accounts that are not setup yet; however Exchange just bounces the emails with no errors.

• AWS Load balancer connection reset

  - by joshmmo

  I have an ELB set up with two instances. The issue I have with it is that when I do not add www. to it, the ELB just hangs. This is some info I get when I spider with wget: Spider mode enabled. Check if remote file exists. --2013-06-20 13:40:54-- http://learning.example.com/ Resolving learning.example.com... 54.xxx.x.x53, 50.xx.xxx.x71 Connecting to learning.example.com|54.xxx.x.x53|:80... connected. HTTP request sent, awaiting response... No data received. Retrying. when I add www. it works great. I have a GoDaddy SSL cert that I added to the listener section that covers 3 domains, www.learning.example.com, files.learning.example.com and learning.example.com. These are my listener settings: - HTTP 80 HTTPS 443 N/A N/A - SSL 443 SSL 443 Change canvasNew (Change) My EC2 instances are running apache2 on Ubuntu 12.04. I will be happy to post my vhosts file if needed. However, when I ran the server with the domains pointing to just one EC2 instance things worked fine. How can I fix this issue for learning.example.com? Why does www work just fine? A second question would be what is the difference between instance protocol and load balancer protocol? EDIT: Here are the dig results for learning.example.com from yesterday. I changed the DNS entry to point to one instance to make sure it was the elb. When I switch it back I will do it for www.learning.example.com ; <<>> DiG 9.9.1-P2 <<>> learning.example.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 20210 ;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;learning.example.com.

It's running great. www and the non-www url work perfectly fine. Its only when I switch things to the ELB that learning.example.com hangs and www.learning.example.com works. Hopefully you can get some ideas flowing.

• Software for RAID Failure Alerts?

  - by QF_Developer

  I have two 256 GB Samsung 840 Pro SSD disks in a RAID 1 array. I would like to receive a notification if one of the disks in the array fails. Can anybody recommend an application I can install on the server to fire an email if such an event occurs? Here are some additional specs: Supermicro X9SCM-IIF motherboard utilising the hardware RAID controller. OS = Windows 2012 Standard Also is it possible to simulate a disk failure by pulling it out of the bay? SSDs appear to fail close together when in a mirrored config so I'd like to know ASAP if one goes down so I can swap them out with minimum delay. UPDATE 26th June 2013 ------------------------ None of the software that ships with the Supermicro X9SCM-* motherboards offer support for RAID monitoring. As has been pointed out here, these boards are built on an Intel chipset for RAID and so I installed Intel Rapid Storage Technology that supports automated email notifications on RAID failure http://www.intel.com/support/chipsets/imsm/sb/cs-020784.htm One small issue, the software only allows you to send email notifications without SMTP authentication. There's a bunch of different workarounds here: http://communities.intel.com/thread/30771

• Nginx, logrotate and empty files

  - by tzulberti

  I have a problem with nginx/logrotate. The problems is that nginx is logging access to 2 files (main and data). I have the following contrab setting: 0 * * * * /usr/sbin/logrotate -f /home/orwell/orwell-setup/bin/logrotate-nginx And the file "logrotate-nginx" has the following content: /tmp/data.log { rotate 90 daily missingok notifempty size 1 sharedscripts postrotate [ ! -f /tmp/nginx.pid ] || kill -USR1 `cat /tmp/nginx.pid` MORE THINGS endscript } /tmp/main.log { rotate 90 daily missingok notifempty size 1 sharedscripts postrotate [ ! -f /tmp/nginx.pid ] || kill -USR1 `cat /tmp/nginx.pid` MORE THINGS endscript } The work is done in the two files, but there is a problem that nginx stops logging into those files. Both files are created, but they are empty. Any ideas why nginx stop logging info to both files?

• How to know if it's phishing or not in android apps?

  - by Zakaria Dza

  In IM apps (not only), there is a browser frame that appears and prompts for example to connect to facebook account, ebuddy for example (can't post pictures :( ) http://nsa34.casimages.com/img/2013/06/26//130626121230193046.jpg My question is: how can I know if this frame is from facebook.com and not a phishing website. I know that the apps in the play store are legit (mostly at least), but how can we trust apps that we install from outside the store? Or is there any way to check the credentials form action? Thanks for your answers and sorry for my bad english. (And sorry for the picture, couldn't make a screenshot ;-) )

• Split a table in Word without losing row title

  - by Shane Hsu

  Word has the feature to repeat title row of a table when a table is so long that it spans a bunch of pages. I need to categorize my data into several pages, and I did that by splitting the table and insert page split to put them all in a page of itself. So now I got several page of data, but only the first page has title row. Is there anyway else to do this beside manually adding the title row to all the other pages? Original data: _________________ | Cat.

  I have set up a rule to forward incoming emails from Outlook to my Gmail account. The problem is that certain mails in which I'm a CC (about 1000/day monitoring system running status) are also forwarded to my Gmail and fill up my account very quickly. I have set up rules in Outlook to move those emails to a certain folder (called Monitored_Emails), but I don't know how to filter those emails so they don't forward to Gmail. How can I set this rule to forward all emails except those in a certain folder name?

• Ping or accessing WAN IP from LAN results in failure on only one box

  - by ComputerUserGuy

  Morning/evening gents. I purchased a radical domain name today to set up a name for my services and to set up SSL. I configured the SSL fine and all but when I went to my website I couldn't connect. I can connect to the site with any other device in my house and my friend can connect to it as well from outside of the LAN. I am hosting the services with my computer and I can't access the service. Whenever I ping it using the command prompt I get a result of "General Failure.". It saddens me that they couldn't make a better message as it kind of brings me down. I'm not sure what's the deal here as I have all of my firewalls down and my ports are forwarded. Running Windows 7. Thanks for the assistance chaps.

• Wake a Mac display from sleep via SSH

  - by MaxGabriel

  I'm using Jenkins as a CI server, where I'm SSHing into an iMac running OS X Mountain Lion (10.8.4) to run some UIAutomation integrations tests on an iOS app. The iMac actually sits 10 ft from me (but across a table) so I'm able to see the screen. However, the tests don't wake up the display, so I often can't see them. Is there a way to wake up the display from the terminal once Jenkins has SSHed in? So far I have tried using Applescript to press an arrow key, and using the Wake Assist application. I also tried setting the wake schedule to be the current date. Finally, I tried using the caffeinate command: caffeinate -t 300 &. The computer's "Wake for Wi-Fi access" checkbox is enabled. So far my best workaround is to just set the iMac to stay awake for atleast 3 hours. However, it'd be nice to keep normal sleep behavior, as I hypothesize that the screen waking from sleep would alert me visually that the integration tests are running. It's also significantly cooler :)
