  • 389 DS Achitecture for Multiple Sites

    - by Kyle Flavin
    I'm looking to deploy 389 Directory in my environment to replace an existing iPlanet installation. I would be using it primarily to store user account data for authentication purposes. I have two physically separate data centers that I would like to share the same directory tree. My initial thinking is to setup 389 DS as follows: -A Master/Consumer in DataCenter A -A Master/Consumer in DataCenter B -Replication agreement between both masters, to mirror the directory tree in both environments. Does this sound like a reasonable approach? Is there a better way to do it? (ie: four masters?) Is there documentation for best practices when setting up 389 DS in situations such as this? Thanks.

  • Permissions in OS X for iTunes library with multiple users

    - by John
    I currently have a lot of music on an external drive and my iTunes set up from there. However, periodically, when the external drive isn't connected, iTunes will default back to the library location of my home directory user path. I don't want to mess with an external drive, as my Mac's HD is large enough to house the music collection. However, I have 4 family members – all with their own logins – using this same gob of music. I don't want four copies of the library, only one with all libraries referencing it. So, what I want to do is: Move all music files to a shared directory at /Macintosh HD/users/music. I created this directory and adjusted permissions, so all four users can read and write to this directory. Get all four accounts to reference this library instead of the external or local home locations I am hoping I can just check the box to keep library organized in my account, which is the admin and let iTunes move it all. Then delete current libraries for each account and re-add from the new shared location. Will the iTunes organization process cause permissions issues either by setting permissions to all the files access to my account only or write permissions or any other 'gotcha'? I am having a hard time coming up with a smooth solution that won't break everything and cause me to have mega duplicates or access issues. I would prefer not to do any XML library file editing if possible. Am I dreaming?

  • Hyper-V with multiple physical networks

    - by Yaman
    I have Hyper-V on my laptop with a wireless and Ethernet card, sometimes I connect using wireless card, and sometimes using the Ethernet cable. I am trying to configure Hyper-v to work always with internet provided to virtual machine. I have tried to create 2 virtual switches, one external to the Wireless network card, and the other one external to the Ethernet card. What happens is that the wireless network creates a bridge object in the network and sharing center\Network connections of windows 8, while the Ethernet does not. Unfortunately, they do not work together as external, i have to set the connected one to external and the other one as external, I also have to go to the properties of the bridge and virtual Ethernet properties to uncheck and check some components like: Client for Microsoft Networks Deterministic Network Enhancer VMWare Bridge Protocol QoS Packet Scheduler File and Printer Sharing for Microsoft Networks In order to make things work. Sometimes I keep the wireless network switch external, and go to another location (another wireless network), and it disconnects, i have to reconfigure the switches. Is there a way to do the configuration once and remain working wherever I connect, whether its Wireless or Ethernet and on any network with DHCP?

  • RouterLess, house-wired network using multiple powerline adapters

    - by Cliff Arnell
    related to the 'old days' of one ethernet cable tapped with Ts for each monitor.... my question might be very simple... or not. I have an over-the-air internet provider with a wire dish with a powered transceiver and cat5 cable out of the providers supplied modem. I'm presently connecting the output of the modem into my wireless router which sends the internet signal all over the house. Standard stuff, I believe. My Question. Can I just connect the output of the modem into 1 powerline adapter and tie all my equipment such as computer, printer, laptop, Tivo recorder, etc. into 1-each local powerline adapters located near each devices resulting in a 'house-wired' network and no router? I'm bothered by the idea that my over-the-air provider might be using something in my router to establish and keep my IP connection alive. I did have to configure the router for my IP, a router which, in my proposed scenario, would no longer exist. Thank you for your help.

  • dhclient append settings from multiple DHCP servers

    - by Brian
    I have a server with two interfaces connected to two separate networks, using DHCP for both. When dhclient is writing /etc/resolv.conf, I would like it to append settings that aren't already there. For instance, if I receive from one DHCP server: nameserver 10.0.0.1 search one.mydomain.com and from another: nameserver 10.1.1.254 search two.mydomain.com Then resolv.conf should look like this: search one.mydomain.com two.mydomain.com nameserver 10.0.0.1 nameserver 10.1.1.254 At the moment, it seems the last dhclient overwrites whatever was there. I know I can preconfigure settings in dhclient.conf using supercede or append, but then I have to hard-code the values. I've scoured the man page for dhclient, but it seems like dhclient prefers to work alone (i.e. not in conjunction with any other dhclients)...or am I missing something?

  • Restreaming video from XSplit to multiple JustinTV/TwitchTV channels in different resolutions and bitrates

    - by lmojzis
    I have a really simple question but the answer may be a little more complex I guess. Okay. Let's go. I have an Application called Xsplit Broadcaster (http://www.xsplit.com/). It supports streaming video through RTMP. Now what I want to do is this: +--(720p)--> TwitchTV FirstChannel XSplit --(720p RTMP)-->[MyTranscodingServer]--+ +--(360p)--> TwitchTV SecondChannel Is there a simple way to do this? Additional info: Both channels accept standard RTMP stream on their RTMP endpoint using either username/password or streamkey. The server operating system is GNU/Linux

  • multiple definition in header file

    - by Jérôme
    Here is a small code-example from which I'd like to ask a question : complex.h : #ifndef COMPLEX_H #define COMPLEX_H #include <iostream> class Complex { public: Complex(float Real, float Imaginary); float real() const { return m_Real; }; private: friend std::ostream& operator<<(std::ostream& o, const Complex& Cplx); float m_Real; float m_Imaginary; }; std::ostream& operator<<(std::ostream& o, const Complex& Cplx) { return o << Cplx.m_Real << " i" << Cplx.m_Imaginary; } #endif // COMPLEX_H complex.cpp : #include "complex.h" Complex::Complex(float Real, float Imaginary) { m_Real = Real; m_Imaginary = Imaginary; } main.cpp : #include "complex.h" #include <iostream> int main() { Complex Foo(3.4, 4.5); std::cout << Foo << "\n"; return 0; } When compiling this code, I get the following error : multiple definition of operator<<(std::ostream&, Complex const&) I've found that making this fonction inline solves the problem, but I don't understand why. Why does the compiler complain about multiple definition ? My header file is guarded (with #define COMPLEX_H). And, if complaining about the operator<< fonction, why not complain about the public real() fonction, which is defined in the header as well ? And is there another solution as using the inline keyword ?

  • Nginx Multiple Domains

    - by showFocus
    I am trying to add a second virtual host to nginx. When i go to the new domain it redirects to the old one. I have tried restarting Nginx, rebooting the server.

  • NAT Policy Inbound Source Problem on SonicWall TZ-210 with Multiple DSL Lines

    - by HK1
    We recently added three more DSL connections to our SonicWall TZ-210. My NAT Policies work fine as long as I leave them set with an inbound interface of X1, which hosts our original DSL connection. However, I'd like to change some of the NAT Policies to use inbound source/interface X2, X3, X4 or Any. In my initial tests, when I change one of the policies to use an inbound interface of X2, that port forward policy does not work at all. Traffic never makes it to the internal destination. What could be the problem?

  • Session persistence between multiple Rails / Unicorn servers with Redis as session_store on AWS

    - by d_ethier
    I've got 2 nginx EC2 instances pointing to 2 Unicorn EC2 instances in a round robin load balanced configuration. The two nginx instances are being the Elastic Load Balancer. Both Unicorn instances have a Redis session_store configured which is in a master/slave configuration with an Elastic IP attached to the master. I've tried configuring the session stickiness on the load balancer, but sessions are lost on each page refresh. I'm using the redis-store gem for the session_store configuration and redis support. Anyone have any ideas as to why this is not working?

  • SELinux - Allow multiple services access to same /home/dir

    - by Mike Purcell
    I currently have SELinux enabled and have been able to configure apache to allow access to /home/src/web with a chcon command granting the 'httpd_sys_content_t' type. But now I am trying to serve the rsyslogd.conf file from the same directory, but every time I start rsyslogd I see an entry in my audit log saying that rsyslogd was denied access. My question is, is it possible to grant two applications the ability to access the same directory, while still keeping SELinux enabled? Current perms on /home/src: drwxr-xr-x. src src unconfined_u:object_r:httpd_sys_content_t:s0 src Audit log message: type=AVC msg=audit(1349113476.272:1154): avc: denied { search } for pid=9975 comm="rsyslogd" name="/" dev=dm-2 ino=2 scontext=unconfined_u:system_r:syslogd_t:s0 tcontext=system_u:object_r:home_root_t:s0 tclass=dir type=SYSCALL msg=audit(1349113476.272:1154): arch=c000003e syscall=2 success=no exit=-13 a0=7f9ef0c027f5 a1=0 a2=1b6 a3=0 items=0 ppid=9974 pid=9975 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=30 comm="rsyslogd" exe="/sbin/rsyslogd" subj=unconfined_u:system_r:syslogd_t:s0 key=(null) -- Edit -- Came across this post, which is sort of what I am trying to accomplish. However when I viewed the list of allowed sebool params, the only relating to syslog was: syslogd_disable_trans (SELinux Service Protection), seems like I can maintain the current SELinux 'type' on the /home/src/ dir, but set the bool on syslogd_disable_trans to false. I wonder if there is a better approach?

  • Printer offline until spooler service is restarted multiple times

    - by Zian Choy
    When I try to print from my ThinkPad to a printer shared through a Windows 7 Homegroup hosted by a desktop computer, I often have to restart the Print Spooler service several times before the job will go through. In particular, this problem occurs when the desktop is in sleep mode when the print job is started and then brought out of sleep mode after the print job has been kicked off. Both computers are running Windows 7 32-bit edition with the latest patches. I have tried the following with no improvement: SNMP registry hack (see MS KB for details) Following the instructions in a blog post entitled "Sharing Printers on Vista 64-bit" Looking at Printer offline until spooler service is restarted

  • How to maintain long-lived python projects w.r.t. dependencies and python versions ?

    - by Gyom
    short version: how can I get rid of the multiple-versions-of-python nightmare ? long version: over the years, I've used several versions of python, and what is worse, several extensions to python (e.g. pygame, pylab, wxPython...). Each time it was on a different setup, with different OSes, sometimes different architectures (like my old PowerPC mac). Nowadays I'm using a mac (OSX 10.6 on x86-64) and it's a dependency nightmare each time I want to revive script older than a few months. Python itself already comes in three different flavours in /usr/bin (2.5, 2.6, 3.1), but I had to install 2.4 from macports for pygame, something else (cannot remember what) forced me to install all three others from macports as well, so at the end of the day I'm the happy owner of seven (!) instances of python on my system. But that's not the problem, the problem is, none of them has the right (i.e. same set of) libraries installed, some of them are 32bits, some 64bits, and now I'm pretty much lost. For example right now I'm trying to run a three-year-old script (not written by me) which used to use matplotlib/numpy to draw a real-time plot within a rectangle of a wxwidgets window. But I'm failing miserably: py26-wxpython from macports won't install, stock python has wxwidgets included but also has some conflict between 32 bits and 64 bits, and it doesn't have numpy... what a mess ! Obviously, I'm doing things the wrong way. How do you usally cope with all that chaos ?

  • Windows7 home 64bit + Outlook 2010, multiple non-concurrent users

    - by Jim Taylor
    We have one windows computer shared by eight people. I have set up separate login accounts for each user. One account has administrative privileges, the others are standard users. We installed Outlook 2010 with the intention that each user could access their own email separately, without seeing the mail of other users. This has not worked as we intended. When the administrator logs in to each standard user account and starts the outlook mail setup, he is prompted for the administrative password, and then sets up the mail account. When accessing the outlook mail program after setup, each mail account shows as a separate tab in a communal inbox, rather than a separate mail box for each user. How would we accomplish the desired separation of Outlook mail accounts? Thanks for your advice Jim T.

  • Switch Before Firewall / Router - Multiple public IPs

    - by rii
    I currently Have a 10Mbit Full duplex circuit connected to a small unmanaged switch which then connects to a Sonicwall Firewall / Router. I have several public IP addresses (/28) that are assigned to several devices in my setup. Now the problem is the small switch I have was lent to me and needs to be returned, I have replaced this switch with several other switches but for some reason any other switch I use causes the network to become extremely slow. I believe this is a problem with the autonegotiation of theses hubs, so I am thinking of purchasing a small managed switch (cisco 300 series) and making the receiving port on the swith Explicitly 10Mbit Full Duplex and see if this works. My question is, being that this is a managed switch and needs an IP, will I still be able to run my public ips through it? Say the circuit has 70.80.4.1 - 7 will I still be able to assign 70.80.4.2 to my firewall and 70.80.4.3 to my router connected to some other port in the switch? Will I have to assign the switch a public IP address in this range as well for it to "route" to those other devices or does the switch does not care what IPs goes through it while operating as a Layer 2 Switch? Any help would be greatly appreciated. Thanks in advanced!

  • Linux: Can I link multiple destinations via softlinks?

    - by kds1398
    Attempting to end up with something similar to this: $ ls -l lrwxrwxrwx 1 user group 4 Jun 28 2010 foo -> /home/bar lrwxrwxrwx 1 user group 4 Jun 29 2010 foo -> /etc/bar The intention is to be able to move a file to foo & have it go to both destination directories for now. The goal is to eventually unlink /home/bar link after confirming there are no issues with moving the files to /etc/bar. I am restricted in that I am unable to change or add to the process that moves the files.

  • Hosting multiple websites from home

    - by dean nolan
    I have just been accepted for Microsofts Wevsite Spark program which I mainly got for the tools, Visual Studio, Blend. I also have a few of my own websites, personal and a couple of business ones. I also work freelance and sometimes I would like a place to just put a demo up of a clients project. The websites I currently have are all on differnet hosting provders and domain registrars. The WebsiteSpark comes with Windows Server 2008 and SQL Server 2008. It would be really advantagous of me to have all these in one place but also so I have complete control over the database and the environment. So I am thinking over the next 4-6 months of migrating all this to my own server that I will host from home, or maybe even setup at home and then store in a proper datacentre. I was wondering what steps I should take and what to be aware of, specifically: 1) having all these different websites on one computer and having the url got to the proper place. 2) Cost effectiveness? Having the server in home as apposed to datacentre. Most solutions I see charge over £1000 a month to have a machine in datacentre. This is mostly for my own ease of management and shared hosting which I currently have is very limited configuration wise. Would getting a server in house be beneficial for then upgrading to the cloud? What measures should I take with my ISP? I know this is a lot I've asked but just even links to good articles would be good. Thanks

  • Copy large files to multiple machines on a LAN

    - by Jonathan Callen
    I have a few large files that I need to copy from one Linux machine to about 20 other Linux machines, all on the same LAN as quickly as is feasible. What tools/methods would be best for copying these files, noting that this is not going to be a one-time copy. These machines will never be connected to the Internet, and security is not an issue. Update: The reason for my asking this is because (as I understand it) we are currently using scp in serial to copy the files to each of the machines and I have been informed that this is "too slow" and a faster alternative is being sought. According to what I have been told, attempting to parallelize the scp calls simply slows it down further due to hard drive seeks.

  • Fill down in Excel, but based on multiple values

    - by Jenn D.
    I have spreadsheets (not created by me) that have blank entries in one column where they should really have data. I want to take every empty cell and fill it with the nearest value above it. I'm looking for as little manual intervention as possible, because I'll have to do it repeatedly. I thought some previous version of Excel, or maybe another spreadsheet from the distant past, would do this by default -- that is, if you selected the column with foo and bar, and chose the equivalent of "fill down", you would get what's in the WANT column. What I actually get in Excel is the GET column. HAVE: WANT: GET: foo 1 foo 1 foo 1 2 foo 2 foo 2 bar 1 bar 1 foo 1 2 bar 2 foo 2 3 bar 3 foo 3 I'm worried that this might need a macro to be done properly. I used to be a whiz with Excel macros, and then suddenly they were all in VB. My fallback position will be to dump the whole thing to CSV and write a Python script, but if there's any way to do it in Excel that would be much preferable. Even if it involves a couple of different manual steps, that's fine; just not one step per group of lines. That is, a process of "copy the column, do X to it, cut and paste it back" would work, but "do X for each occurrence of foo or bar" won't. The files are too big for that. Any thoughts are appreciated!

  • How to synchonise address books across multiple PC's

    - by Rob
    I am using Thunderbird 15.0.1 on two different Windows computers (Vista and Win 7). I maintain the email list for a local club, and often need to send out emails to all members from my home and office Pc's. I use a Thunderbird Address Book to maintain a list of club members and would like any changes made to that list to synchronise to both machines. Can anyone recommend a good way of doing this? I've found a couple of extensions that claim to do this, but both seem to have review that suggest they no longer function correctly since they are quite old extensions. Is there another tool that I would be better off using? Rob

  • Multiple users writing to one Samba mount point in OSX

    - by Sam
    I have an OSX box containing a script which writes a unique file to a Samba share. The first part of the script mounts the share. On the machine are 2 users- UserA and UserB. Each requires to run this script at any given time however only the user who mounted the share is able to write to it. I really need both users to have rwx access. Here is what I have tried: Mounting then chmod'ing the mountpoint (no effect- overruled by Samba server?) chmod'ing the mountpoint then mounting (same as above) sudo mount_smbfs Both users have admin privileges. Ideally a solution would be executable by one of the users (contained in the script) and not rely on mounting at machine boot time. Any ideas appreciated, thanks!

  • Configuring nginx server to handle requests from multiple domains

    - by KillABug
    Use Case:- I am working on a web application which allows to create HTML templates and publish them on amazon S3.Now to publish the websites I use nginx as a proxy server. What the proxy server does is,when a user enters the website URL,I want to identify how to check if the request comes from my application i.e app.mysite.com(This won't change) and route it to apache for regular access,if its coming from some other domain like a regular URL www.mysite.com(This needs to be handled dynamically.Can be random) it goes to the S3 bucket that hosts the template. My current configuration is: user nginx; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; charset utf-8; keepalive_timeout 65; server_tokens off; sendfile on; tcp_nopush on; tcp_nodelay off; Default Server Block to catch undefined host names server { listen 80; server_name app.mysite.com; access_log off; error_log off; location / { proxy_pass http://127.0.0.1:8080; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_redirect off; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; client_max_body_size 10m; client_body_buffer_size 128k; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; } } } Load all the sites include /etc/nginx/conf.d/*.conf; Updates as I was not clear enough :- My question is how can I handle both the domains in the config file.My nginx is a proxy server on port 80 on an EC2 instance.This also hosts my application that runs on apache on a differnet port.So any request coming for my application will come from a domain app.mysite.com and I also want to proxy the hosted templates on S3 which are inside a bucket say sites.mysite.com/coolsite.com/index.html.So if someone hits coolsite.com I want to proxy it to the folder sites.mysite.com/coolsite.com/index.html and not to app.syartee.com.Hope I am clear The other server block: # Server for S3 server { # Listen on port 80 for all IPs associated with your machine listen 80; # Catch all other server names server_name _; //I want it to handle other domains then app.mysite.com # This code gets the host without www. in front and places it inside # the $host_without_www variable # If someone requests www.coolsite.com, then $host_without_www will have the value coolsite.com set $host_without_www $host; if ($host ~* www\.(.*)) { set $host_without_www $1; } location / { # This code rewrites the original request, and adds the host without www in front # E.g. if someone requests # /directory/file.ext?param=value # from the coolsite.com site the request is rewritten to # /coolsite.com/directory/file.ext?param=value set $foo 'http://sites.mysite.com'; # echo "$foo"; rewrite ^(.*)$ $foo/$host_without_www$1 break; # The rewritten request is passed to S3 proxy_pass http://sites.mysite.com; include /etc/nginx/proxy_params; } } Also I understand I will have to make the DNS changes in the cname of the domain.I guess I will have to add app.mysite.com under the CNAME of the template domain name?Please correct if wrong. Thank you for your time
