    I was using a script to perform rsync in sudo crontab. The script does a 2-way rsync (from serverA to serverB and reverse). After i reboot both the server machines, the rsync is not working in sudo crontab. I also setup a new cronjob and it fails, The error is: rsync error: unexplained error (code 255) at io.c(600) [sender=3.0.6] rsync: connection unexpectedly closed (0 bytes received so far) [receiver] However, when run from terminal, the rync script works as expected without issues. please help.

  • Subnet calculator for MS Excel

    - by Martin
    I quite often use the handy subnet calculator here: http://www.subnet-calculator.com/ Which I find very useful. However, does anyone have details/a link for a version of this that offers similar functionality but is in an excel spreadsheet. I could then include it in a worksheet and I wouldn't have to keep visiting the website. Also handy if I don't have internet access - which can often be the case when I need it. Many thanks

  • exim4 redirect mail sent to *@domain1.example.com to *@domain2.example.com

    - by nightcoder
    Current situation: We have a VPS that hosts a website example.org. Exim is configured to work as a smarthost. All emails sent through exim are successfully relayed to another mail server (that is working on example.com). Goal: To forward mail sent to *@example.org to *@example.com, i.e. change the recipient's address from *@example.org to *@example.com. Problem: If I send email to address *@example.org, then it seems exim doesn't change the address, it still relays the message to another mail server but recipient is still *@example.org. Maybe the redirect is not applied for some reason. Configuration and logs: /etc/exim4/update-exim4.conf.conf: dc_eximconfig_configtype='smarthost' dc_other_hostnames='' dc_local_interfaces='' dc_readhost='example.org' dc_relay_domains='example.org' dc_minimaldns='false' dc_relay_nets='0.0.0.0/32' dc_smarthost='example.com::26' CFILEMODE='644' dc_use_split_config='false' dc_hide_mailname='true' dc_mailname_in_oh='true' dc_localdelivery='maildir_home' /etc/exim4/conf.d/router/999_exim4-config_redirect (created by me): domain_redirect: debug_print = "R: forward for $local_part@$domain" driver = redirect domains = example.org data = [email protected] (for now data is set to a specific address for simplicity and testing) exim log when sending email to [email protected] (should be redirected to [email protected]): 2012-03-20 19:40:07 1SA4ud-0005Dw-7k <= [email protected] U=www-data P=local S=657 2012-03-20 19:40:08 1SA4ud-0005Dw-7k => [email protected] R=smarthost T=remote_smtp_smarthost H=domain2.com [184.172.146.66] X=TLS1.0:RSA_AES_256_CBC_SHA1:32 DN="C=US,2.5.4.17=#13053737303932,ST=TX,L=Houston,STREET=Suite 400,STREET=11251 Northwest Freeway,O=HostGator.com,OU=HostGator.com,OU=Comodo PremiumSSL Wildcard,CN=*.hostgator.com" 2012-03-20 19:40:08 1SA4ud-0005Dw-7k Completed So, the address is not changed :( Please help!

  • Python install issue on Mac OS X

    - by Michael Waterfall
    I have been using the standard python that comes with OS X Lion (2.7.2) but I wanted to build a UCS-4 version to handle 4-byte unicode characters better. I had already installed pip and packages like pytz, virtualenv and virtualenvwrapper, etc., and these are installed in /Library/Python/2.7/site-packages. My $PATH is /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin. To build a new version of python on the machine (outside of any project specific virtual environments, that will come later), I followed the instructions on this article and managed to build it in /usr/local/bin. The problem is that when I launched a new bash window, I got the following virtualenvwrapper error: Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: No module named virtualenvwrapper.hook_loader virtualenvwrapper.sh: There was a problem running the initialization hooks. If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenv has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python and that PATH is set properly. The instructions said to move /usr/local/bin to the top of the /etc/paths file, and since then I've noticed some strange issues. I installed pip into /usr/local/bin and now I have assumed that since I'm working in /usr/local/bin, and the newly installed python's site packages is now located in /usr/local/lib/python2.7/site-packages, when I do pip freeze, it should be empty as nothing is installed there yet. However, pip freeze still reports things installed in the old (OS X) site-packages folder. Here's some info after the build: $ which python /usr/local/bin/python $ which pip /usr/local/bin/pip $ echo $PATH /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin When I uninstall a python package with pip, it removes it from the old site-packages folder as expected. When I install it again, instead of installing it in /usr/local/lib/python2.7/site-packages, it installs it in /Library/Python/2.7/site-packages (verified by attempting to install it again and receiving Requirement already satisfied (use --upgrade to upgrade): pytz in /Library/Python/2.7/site-packages ). How is it getting that path for the old site-packages folder? Why won't it install it in the correct location for the python install it's using? I'm getting several other issues since promoting /usr/local/bin but I think if I understand this I'll be able to get somewhere. Can anyone see what's happening? If you need any more info I'll be happy to provide it.

  • LSI 9260-8i w/ 6 256gb SSDs - RAID 5, 6, 10, or bad idea overall?

    - by Michael Pearson
    We're provisioning a new production server for our reasonably busy website. Our choice of host have available a 6 drive configuration with a LSI 9260-8i card. My initial thought was to fill all six bays with SSDs (Intel 520 256gb) and set them up in RAID. Good, bad, or terrible idea? Can the card handle it? Should we be using RAID 5, 6 or 10? This would be the first time the provider have filled all six slots for this rackmount with SSDs, so they're a bit hesitant. I'm wondering if somebody else with this card has done something similar in a production environment. We do about 43gb of writes per day and currently use about 300gb of storage. The server acts as webserver, database, and image store for approx 1 million files. The plan is to underprovision the SSDs by approximately 10% to 20% to increase their overall lifespan & performance. The fallback option is 2x480gb SSDs in RAID 1 and another 2x1TB HDDs in RAID 1. The motivation behind this is that the server rental cost difference between 2xSSDs and 6xSSDs is minimal (compared to the overall cost of the rental). We do not have any special high-IOPs requirements. However, if the configuration is known to work, I don't see a good reason to not use it and not have to worry about having separate 'fast and small' and 'slow and large' disks.

    I'm having an issue that is a little strange. I have a cPanel webserver that I own and have root. I was testing out emailing and noticed some issues.

  • Enterprise user management

    - by Eduardo
    I am looking for an enterprise user management system that meets these requirements: Delegated user administration: The group manager should be able to grant access to his supervised employees (without having to contact any administrator either to grant access or maybe create users). A group manager should be able to create other groups and restrict any permission he already has where he can add supervised employees. If a manager removes access to a supervised group, then all the subgroups will also lose access. Web based User Interface. LDAP interface to query users and groups (or may not exist at all if it is integrated in a single application). Do you know if there are any system that meet these requirements?

  • Nginx / uWsgi / Django site can handle more traffic with rewrite URL

    - by Ludo
    Hi there. I'm running a Django app, using uWsgi behind Nginx. I've been doing some performance tuning and load testing using ApacheBench and have discovered something unexpected which I wonder if someone could explain for me. In my Nginx config I have a rewrite directive which catches lots of different URL permutations and then forwards them to the canonical URL I wish to use, eg, it traps www.mysite.com/whatever, www.mysite.co.uk/whatever and forwards them all to http://mysite.com/whatever. If I load test against any of the URLs listed with a redirect (ie, NOT the canonical URL which it is eventually forwarded to), it can serve 15000 concurrent connections without breaking a sweat. If I load test against the canonical URL, which the above test I would have expected got forwarded to anyway, it can't handle nearly as much. It will drop about 4000 of the 15000 requests, and can only handle about 9000 reliably. This is the command line I'm using to test: ab -c15000 -n15000 http://www.mysite.com/somepath/ and ab -c15000 -n15000 http://mysite.com/somepath/ I've tried several different types - it makes no different which order I do them in. This doesn't make sense to me - I can understand why the requests involving a redirect may not handle quite so many concurrent connections, but it's happening the other way round. Can anyone explain? I'd really prefer it if the canonical URL was the one which could handle more traffic. I'll post my Nginx config below. Thanks loads for any help! server { server_name www.somesite.com somesite.net www.somesite.net somesite.co.uk www.somesite.co.uk; rewrite ^(.*) http://somesite.com$1 permanent; } server { root /home/django/domains/somesite.com/live/somesite/; server_name somesite.com somesite-live.myserver.somesite.com; access_log /home/django/domains/somesite.com/live/log/nginx.log; location / { uwsgi_pass unix:////tmp/somesite-live.sock; include uwsgi_params; } location /media { try_files $uri $uri/ /index.html; } location /site_media { try_files $uri $uri/ /index.html; } location = /favicon.ico { empty_gif; } }

  • CentOS security for lazy admins

    - by Robby75
    I'm running CentOS 5.5 (basic LAMP with Parallels Power Panel and Plesk) and have thus far neglected security (because it's not my full-time job, there is always something more important on my todo-list). My server does not contain any secret data and also no lives depend on it - Basically what I want is to make sure it does not become part of a botnet, that is "good enough" security in my case. Anyway, I don't want to become a full-time paranoid admin (like constantly watching and patching everything because of some obscure problem), I also don't care about most security problems like DOS attacks or problems that only exist when using some arcane settings. I'm in search of a "happy medium", for example a list of known important problems in the default installation of CentOS 5.5 and/or a list of security problems that have actually been exploited - not the typical endless list of buffer overflows that "maybe" a problem in some special case. The problem that I have with the usually recommended approaches (joining mailing lists, etc.) is that the really important problems (something where an exploit exists, that is exploitable in a common setup and where the attacker can do something really useful - i.e. not a DOS) are completely and utterly swamped by millions of tiny security alerts that surely are important for high-security servers, but not for me. Thanks for all suggestions!

  • Powershell ActiveDirectory-Module on SBS-2008?

    - by wullxz
    I read plenty of tutorials that describe how to install ADWS (ActiveDirectory Webservices) and Powershell. But I never saw any hint about installing ADWS on a SBS-2008 in order to work with Powershell and ActiveDirectory-module. I know, that I should use the SBS-Console to manage users, but there are tasks where it could be good to use AD as database of users and computers to loop through them (e.g. remote-commands on all workstations, find out user-lastlogon-times etc). Can anybody say, if it's ok (and supported?) to install AD-Powershell-Module and ADWS on a SBS-2008? Thanks

  • What is the best way to clone Win7 machines?

    - by John Hoge
    I'm looking to buy 5 new Win7 boxes and would like to ease deployment by cloning the OS. What I would like to do is install a fresh OS (Dell doesn't seem to sell machines without preinstalled crapware anymore) and then install a few apps on the first one. Once it is just right, I want to clone the OS and install the image on the other four machines and just change the machine name. Is this possible to do without any extra third party software? What I am thinking of doing is backing up the disk image of the first machine to a network share, and then booting the others to the windows install DVD and restoring the same image on each machine. Has anyone had any luck with this technique?

  • How to Fix Mail Server SSL?

  • PXE in an 802.1X environment

    - by newmanth
    My organization is about to implement 802.1X on our enterprise, but we currently use PXE-based OS deployment sequences in SCCM. I'm looking for a way to continue using PXE in an 802.1X environment. Our infrastructure uses Cisco network gear running at 12.2 (or newer). We are an all Windows network and all clients support 802.1X. All new workstations have Intel AMT available (but not factory configured). In a worst case scenario, we'll use a guest vlan for OSD, but I'd rather have the OSD occur in an authenticated session. I've seen white papers that describe using AMT to act as a supplicant for PXE boot, but can't find any implementation details...

  • Rewind print job under Windows Server 2008

    - by FooLman
    Hello, We are in the transition from Novell NetWare to Windows server 2008. In case of the printer server we print jobs thousands of pages long. NetWare printer manager has a handy function which allows to rewind a print job to a specified page. In case of a paper jam at the 750 page on a 800 page document this is really convenient. Does anybody know if there is a solution for this? The lists printed are in plain ascii lists with printer command characters embedded, and we are using dot matrix printers. Thanks for any help or suggestion. Regards.

  • What is the minimal steps to setup a client-server network using Windows Server 2008 R2 standard?

    - by Motivated Student
    Background I have One computer server with Win Server 2008 R2 standard installed but it has not been configured. This server has 2 LAN adapters. One adapter is connected to ISP and the other one connected to HUB/Switch. Other computers working as clients are connected to the same HUB/Switch to which the server is connected. IP Printers, IP scanners, IP camera are also connected to the same HUB/Switch. Note: I am a newbie. I only know how to plug RJ-45 sockets and assembly computer peripherals. I have no prior experience in Windows Server at all. Please teach me from the newbie's point of view. Objective I want to establish the following: Each client can access the internet, printers, scanners after it has been successfully authenticated by the server. Unauthenticated clients cannot access the internet, printers, etc. The server hosts a local site. Clients can browse internally using a private domain www.company.com. If the same domain name has been used by other on the internet, my private domain must override the public domain.

  • Using .htaccess to protect direct access of files

    - by claydough
    We need to prevent direct access of files on our site from someone just entering a URL in their browser. I got this to work by using an htaccess file and it is fine in IE & Safari, but for some reason Firefox doesn't cooperate. I think it has something to do with the way Firefox reports referrers. Here is my code in the .htaccess file. RewriteEngine On RewriteBase / RewriteCond %{HTTP_REFERER} !^http://(my\.)?bigtimbermedia\.com/.*$ [NC] RewriteRule \.(swf|gif|png|jpg|doc|xls|pdf|html|htm|xlsx|docx)$ http://my.bigtimbermedia.com/ [R,L] If you want to see an example of this, try accessing this first... http://my.bigtimbermedia.com/books/bpGreyWolvesflip/index.html It blocks it properly in all browsers. Now if you go to this URL and click on the link, it works in IE and Safari, but Firefox chokes and seems like it is in a loop. Any ideas how I can get this to work in Firefox? Thanks!

  • Getting Squid to authenticate with kerberos and Windows 2008/2003/7/XP

    - by Harley
    This is something I setup recently and was quite a big pain. My environment was getting squid to authenticate a Windows 7 client against a Windows 2008 Server invisibly. NTLM is not really an option, as using it requires a registry change on each client. MS have been recommending Kerberos since Windows 2000, so it's finally time to get with the program. Many, many thanks to Markus Moeller of the Squid mailing lists for helping to get this working.

  • Sporadic crash of master-slave MySQL replication process

    - by obarshay
    Hello, I was wondering if someone has experienced this and can perhaps provide some insight into this issue. We have a plan-vanilla MySQL master-slave replication set up. The tables are MyISAM and the master can get quite read/write active. We use the slave instance to perform full daily backups in order to avoid bringing down the master server. The backup process does the following: STOP SLAVE SQL_THREAD mysqlhotcopy all tables START SLAVE SQL_THREAD Every once in a while (once a month or so) the replication breaks with varying error messages indicating a corrupt query or log file.

  • Connection reset by peer: mod_fcgid: error reading data from FastCGI server Issues

    - by user145857
    Help is greatly needed for our server. We are experiencing random "Connection reset by peer: mod_fcgid: error reading data from FastCGI server" errors which cause a 500 internal server error. If the page is then reloaded it loads normally as it should. We are running MPM Worker with mod FCGID to handle PHP. We had APC cache enabled but disabled it recently to see if it would fix the problem, but the random mod FCGID errors are still continuing. No other opcode cache is active now. Our settings are below: <IfModule worker.c> MinSpareThreads 25 MaxSpareThreads 150 ThreadsPerChild 25 ThreadLimit 100 ServerLimit 700 MaxClients 700 MaxRequestsPerChild 0 </IfModule> <IfModule mod_fcgid.c> FcgidMaxRequestLen 1073741824 FcgidMaxRequestsPerProcess 2000 FcgidMaxProcessesPerClass 100 FcgidMinProcessesPerClass 0 FcgidConnectTimeout 300 FcgidIOTimeout 900 FcgidFixPathinfo 1 FcgidIdleTimeout 300 FcgidIdleScanInterval 120 FcgidBusyTimeout 300 FcgidBusyScanInterval 120 FcgidErrorScanInterval 12 FcgidZombieScanInterval 12 FcgidProcessLifeTime 3600 </IfModule> The server is a 64 core 2.1 GHZ 94 GB RAM so it has some power. Some of the fcgid timeout settings are higher because we run large reports which take up to 15 minutes. Any help is greatly appreciated! Just to clarify, the random fcgid errors are occurring when a user clicks a page on our site and the 500 error page loads instantly. This is random and occurrs less than 1% of the time but it is still an issue.

  • default gateway of a host

    - by varun
    if my understanding is correct, the following is what happens when a host A wants to communicate with a machine X outside its network. 1) The host ,checks it routing table to find out if there is any direct routes to the machine. 2) It finds out that the machine is outside its network and has to sent the packets to the default gateway(router) R. 3) The host sents an ARP broadcast to get the mac of the router R. 4) After getting the MAC, the host creates a packet with src IP and MAC as that of the host A, dest IP of the remote machine X and dest MAC of the router R. 5)The router R receives the packet, either drops its or sents its to its next hope, which can be another router or the remote machine X itself. Can anyone explain, how the steps would be, if i set the default gateway of the host A as host A itself...?

  • Cassandra hangs with kernel exception when adding jna jar to classpath

    - by george_h
    I have a fresh installation of cassandra v2.0.8 on a RedHat Enterprise Linux v5. I have added a sym link of the jna.jar in cassandra's /lib folder. I start cassandra and it hangs after printing out the classpath in the terminal. When I check my /var/log/message I see this message Jun 9 07:19:05 Bigdata1 kernel: INFO: task java:4889 blocked for more than 120 seconds. Jun 9 07:19:05 Bigdata1 kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

If I remove the jna.jar symlink then everything is fine. Anyone know why this is happening ?
