• How to Setup Ubuntu Mail Server with Google Apps?

  - by Apreche

  I have a domain, let's call it foobar.com. All of the MX records for foobar.com point to Google's mail servers because I am using Google Apps for your domain to manage it. It's great because everyone gets all the advantages of GMail, but our e-mail addresses aren't @gmail.com. I also have a server. Primarily, it's a web server, but it also serves other things. One of the things it serves is the web site for foobar.com and also sites for various virtual hosts such as shop.foobar.com and forum.foobar.com. The server is running Ubuntu 8.04, because I like using LTS releases in production. The thing is, there are various applications running on the server that need the ability to send out emails. Various applications, like the cron jobs, send me e-mails in case of errors. Some of the web applications need to send e-mail to users when they forget their passwords, to confirm new registered users, etc. Lastly, it's nice to be able to send e-mail from the command line using the mail command, or mutt. How can I setup the mail on the web server to go through the Google apps mail servers? I don't need the web server to receive mail, though that would be cool. I do need it to be able to send mail as any legitimate address @foobar.com. That way the forum application can send mails with [email protected] in the from field, and the ecommerce application will have [email protected] in the from field. Also, by sending the mail through the Google servers, we can avoid a lot of the problems with the e-mails being blocked by various spam filters on the web. Google's SMTP servers are trusted a lot more than mine would be. I'm pretty good with administering Linux systems, but I am absolutely brain dead when it comes to e-mail. I need step by step directions from beginning to end on how to set this up. I need to know every thing to install, and every single change to the configuration files that is necessary. I have tried following various howtos and guides in the past, but none of them were quite right. Either they didn't work at all, or they offered a configuration that is not what I wanted. Please help. Thanks.

• Managing multiple independant domains with Google Apps

  - by Saif Bechan

  I am currently running a server where I have multiple domains with all of them running there own mail server. My plan is to outsource this whole email service and have Google, or competitor, do this for me. Let me start by telling you the setup I have now and want to migrate to Google. Initial setup I have a main domain where I run my server, and my nameserver. This is an important domain because this holds the connection with all my internal applications. For example log messages, cronjob messages, and virus-scan messages are sent to this domain. This email is also registered at my registrar and I use it to communicate with my ISP. Next I run a few independent websites that all need their independent email addresses. This can be on shared space, I don't mind. 1 Gig will be enough for everything I am going to do. Summary: superdomain.com (which only has a catchall for internal use and communication with my ISP) cars.com (independent) flowers.com (independent) foods.com (independent) I am going to be the admin for all of this. The independent domains don't need there own admin panel, they just need email addresses like info@ support@, etc. I do all the managing and they just send and receive emails using the accounts i give them. All of the websites have there different staff that use the accounts. Tried so far I have registered my superdomain, but I can only add aliases to the main domain. If I make all the other domains aliases the emails from [email protected] and [email protected] will have the same inbox. I want them to be separate. is the only way to achieve this by creating an account for each domain? And if so, is there no way of creating a superdomain account where I can edit all these accounts easily without having to log in 4 different places to get my work done. I have searched the Google help forums, and posted questions but without any results so far. Questions Can anyone please give me some advice on what to do. I currently use the free program Google has.

• libreadline history lines combine

  - by jettero

  This has been driving me crazy for about three years. I don't know how to fully describe the problem, but I think I can finally describe a way to recreate it. Your milage may vary. I have a mixture of ubuntu server and desktop machines of various versions and a few gentoo machines with various states of disrepair. They all seem to kindof do their own thing, although with similarities. Try this and let me know if you see the same thing. pop open two xterms (TERM=xterm) resize one so they're not the same issue screen -R test1 in one (TERM=screen) and screen -x test1 in the other hooray, typing in one shows up in the other; although notice that their different size produces artifacts and things issue a couple commands in your shell hit ^AF in the one that doesn't fit quite right, now it fits!! scroll back over the history a little goto 6 Eventually you'll notice a couple history lines combine. If you don't, then it's something unique to my setup, which spans various distributions and computers; so that's a confusing concept to me. If you see the thing I'm seeing then this: bash$ ls -al bash$ ps auxfw becomes this: bash$ ls -al; ps auxfw It doesn't happen every time. I have to really play with it — unless I don't want it to happen, then it always does. On some systems (or combinations), I get a line separator like the example above. On some systems, I do not. That I get the line separator on some systems seems to indicate to me that bash supports this behavior. Its history is entirely handled by libreadline and after perusing (ie, carefully reading) the man pages, I couldn't find a single readline setting for combining two history lines. Nor can I find anything in the bash manpage. So, how can I invoke this on purpose? Or, if I can't do that, how can I disable it completely? I would take either answer as a solution. Currently, I only see it when I don't want it.

• Win-XP Browsers Hang on page load - (waiting for...)

  - by CHarmon

  Hello, I’m having problems with my browsers hanging on loading pages on my desktop machine. I’m using Windows XP Pro with SP3 and fully updated except for IE 8. All three of my browsers, IE 7, Chrome and Firefox are having the same problems. Pages are not being loaded and are hanging on “waiting for …”. The browsers are waiting for the page being loaded or ad servers. Sometimes a page will load but the loading graphic continues to be displayed as if the page were still loading when the page appears to be fully loaded. The problem is bad enough that I can’t really use any of my browsers. I can eventually get most pages to load by stopping and restarting the page load. I have DSL modem with a wireless router and I have been able to eliminate the modem and router from being the source of my problem. My laptop doesn’t have any problems even when hardwired to the router and with the wireless connection disabled. I deleted the NIC and let XP re-install. Also tried a different network cable. Tried the same router port used in the laptop test. One clue that may be important is that I can’t connect to my router using the desktop machine…the page hangs while trying to connect. I can ping the router and I can quickly connect to the router using the laptop. I also can’t use the Windows update process – the page never fully loads. The problem affects other user accounts and even happens in safe mode. I am convinced the problem is with part of the O/S…some layer able to affect all of the browsers. The purpose of this post is to see if anyone has some ideas before I do a XP repair. I have done quite a bit of trouble-shooting: Ran a full anti-virus scan with AVG – no problems. Ran full scans with Spybot, MalwareBytes and Sophos anti-rootkit – no problems. Ran Chkdsk with both options checked. Ran Disk Clean up Defragged RE-installed IE7 Cleared all the browser caches Ran Ccleaner (registry tool) Ran HijackThis – nothing unusual (problem happens in safe mode too) Ran Process Explorer – no unusual processes Used System Restore and fell back several days – no change in the problem Booted to last known good configuration – no change in the problem Ran MicrosoftFixit50199.msi – no change in the problem Any ideas or suggestions would be appreciated…I’m not looking forward to doing a repair on XP. Thanks in advance for any help.

• Weird IIS with Windows Authentication + IE problem

  - by Paulius Maruška

  I have a website running on IIS and using Windows Authentication. All users that are configured to get access to the site are form a AD domain (not local users). In the properties of a Website, I have set to use the AD domain as the realm. Now, when using Firefox, Safari or Chrome - Everything is fine. When the user tries to open the site, he get's the login box. he enters simply "username" and "password" (let's pretend that it's an actual login and password :P) and he get's into the site. When using IE, however, things get nasty. When the user tries to open the site - he get's the login box. User enters the "username" and "password" again, but those get rejected! And when the second time login box pops up - it has the username filled in as "web-server-domain-name\username" which is wrong, because web-server-domain-name is not the domain where all users reside (it's "ad-domain"). I've spent days trying to figure out what's going on... Note, that if I manually enter "ad-domain\username" - I get accepted into the site without problems. So, my guess is that IE sends wrong username if domain is not specified. Anyway, IE is the only browser that triggers this behavior! Is it possible to do a server-side fix? Maybe it's possible to somehow auto-map the users to AD users? If it's not solvable server-side - is there a client-side fix for this? Thank you. PS: I'm more of a programmer than a sys-admin, so configuring servers isn't the strong side of mine... :P UPDATE: @Evan: Yes, "Digest authentication for Windows domain servers" is also enabled. @Eric: IIS version is 6.0. The authentication methods enabled are: Integrated and digest - all other methods are disabled. As for the security log. I looked at it, when doing "username" and "password" login in Chrome/Firefox and when doing "ad-domain\username" and "password" login from IE - the generated log messages are the same (I see no difference, anyway). When entering "username" and "password" I don't see any errors in the security (or any other) log, so can't tell what method it's trying to use. UPDATE 2: As suggested by Eric in the comments - I played around with Fiddler... While playing with it, I noticed, that when "username" and "password" is entered in FF and IE - the "Authorization" header value (encrypted) sent by IE is longer (almost two times) than one sent by FF. I tried to disable Windows Integrated authentication and only leave the Digest enabled - that fixed the problem (meaning, IE used the right realm just like other browsers), but that caused bazillion other problems with my site, because with Digest - user impersonation on the server doesn't work (that causes problems, when connecting to database etc). Any ideas?

• What are incentives (if any) to use WinRT instead of .Net?

  - by Ark-kun

  Let's compare WinRT with .Net .Net .Net is the 13+ years evolution of COM. Three main parts of .Net are execution environment, standard libraries and supported languages. CLR is the native-code execution environment based on COM .Net Framework has a big set of standard libraries (implemented using managed and native code) that can be used from all .Net languages. There are .Net classes that allow using OS APIs. WPF or Silverlight provide a XAML-based UI framework .Net can be used with C++, C#, Javascript, Python, Ruby, VB, LISP, Scheme and many other languages. C++/.Net is a variation of the C++ language that allows interaction with .Net objects. .Net supports inheritance, generics, operator and method overloading and many other features. .Net allows creating apps that run on Windows (XP, 7, 8 Pro (Desktop and Metro), RT, CE, etc), Mac OS, Linux (+ other *nix); iOS, Android, Windows Phone (7, 8); Internet Explorer, Chrome, Firefox; XBox 360, Playstation Suite; raw microprocessors. There is support for creating games (2D/3D) using any managed language or C++. Created by Developer Division WinRT WinRT is based on COM. Three main parts of WinRT are execution environment, standard libraries and supported languages. WinRT has a native-code execution environment based on COM WinRT has a set of standard libraries that more or less can be used from WinRT languages. There are WinRT classes that allow using OS APIs. Unnamed Silverlight clone provides a XAML-based UI framework WinRT can be used with C++, C#, Javascript, VB. C++/CX is a variation of the C++ language that allows interaction with WinRT objects. Custom WinRT components don't support inheritance (classes must be sealed), generics, operator overloading and many other features. WinRT allows creating apps that run on Windows 8 Pro and RT (Metro only); Windows Phone 8 (limited). There is support for creating games (2D/3D) using C++ only. Ordered by Windows Team I think that all the aspects except the last ones are very important for developers. On the other hand it seems that the most important aspect for Microsoft is the last one. So, given the above comparison of conceptually identical technologies, what are incentives (if any) to use WinRT instead of .Net?

• Use windows 7 inside virtual box,as guest i mean, to create a Windows 7 USB using "Windows 7 USB/DVD Download Tool" ? (Linux as host)

  - by Abel Coto

  I want to download the Windows 7 professional iso (x32), from microsoft, and , i can do two things. Or buy a new burner , as mine doesn't work (i am trying to decide what dvd writer i could buy) or use a usb dongle to copy the iso to it , and install it via usb. I want to install Windows 7 in a netbook that now has debian,and in my pc. I think i have to buy only the license for the pc , as the netbook came with windows 7 preinstalled, so i suppose that i can use that serial to activate the windows , although i don't know how to install windows 7 starter instead of professional (i think if you remove a file from the iso, windows let you choose the edition to install). The problem is that in both pcs there isn't any windows , only debian. My father has a netbook with windows 7 starter, but i think it hasn't antivirus (at least until have the Karspersky Internet security for 3 pcs bought ), and i don't trust to make the usb there , if i don't now that there isn't any virus or malware. So i am trying to find a way of Create a Windows 7 usb installation , to at least be able to install windows 7 in the netbook without a external dvd writer. I know that with dd in linux you can copy a debian.iso to the usb , and then install debian with it (i've done it) using something like dd if=win7.iso of=/dev/sdb, but i don't know if this would work for windows 7 iso,and if dd will correctly copy the iso to the usb. I suppose that if you are able to boot and install windows 7 from the usb , is that the method works,and you can forget of problems later with the windows 7 installation (problems because some files could not be copied or like). So , i remembered that Microsoft created a tool to copy the iso to the usb using windows. So i thought that i could install in my pc , virtual box , as i have VT and 8 GB ram in it, and download the iso from microsoft ,install windows 7 in the virtual machine , and then copy the iso inside the machine , donwload the iso tool, and atach a usb to the pc, connect it to the guest , and use the tool to copy the iso to the USB. But i don't now if is possible to use a virtual machine to do this , or the virtualization could give problems with the usb, or something. I have found some minutes ago this How to make a windows 7 usb flash install media, from linux? The first method (dd) is the one i like more , and i trust more ( i don't now if the second method using ms-sys , works well , and if i can trust it. I understand that a iso is like a .rar , but no compressed,only containing the files ,so mount the iso and cp the data inside perhaps is ok. Although the method i like more is the microsoft one (more because is from microsoft , and i suppose they now what they do ,at least with this usb related thing, than anything). Perhaps worth more to buy a external dvd writer haha ... Should the virtual machine method work ?

• OpenVPN multiple servers on the same subnet, high availability

  - by andre

  Hey everyone. Let me start by saying that my Linux experience isn't super awesome but I can usually find my way around things easily. Over at work we have an OpenVPN setup that's been due for some improvement for a while now. The main server (tap mode) runs in our office, behind a rather slow DSL connection. The main problem is that, since I'm usually out of the office, every time I want to access something on the virtual network I have to go through that server to get anywhere else. We have two servers up on 100 Mbit connections that we use for development and production purposes, about 3 more servers in the office (one of them behind a different T1 line for VOIP) and about two dozen clients who use the network on a daily basis from various locations. We've had situations where network routing (outside of our control) would not allow people to reach our main OpenVPN server whilst the other locations were connectable. Also any time someone outside the office wants to fetch something from any of the servers (say, a 500 MB code repository), a whopping 20 KB/s download speed is just unacceptable these days (did I mention slow DSL? ok). We had to implement traffic shaping on this server since maxing out this connection was fairly trivial. I had the thought of running two (or more) OpenVPN servers in the network. These would have to have the same subnet though, as our application relies on virtual network's IP addresses for some of its core functionality. The clients would also preferably retain the same IP addresses but that's not vital. For simplicity, lets call the current server office and the second server I'm setting up, cloud. Call the server on the T1 phone. This proved to be rather complex because as soon as I connect to cloud, I cannot see office. Any routes to a server that would go through office also do not work while I'm connected to cloud (no ping, nothing) and vice-versa. There's no rules for iptables that would be blocking the traffic either. Recently I came across this article on linuxjournal but the solution they provide seems to only cover the use of two servers and somewhat outdated (can't even find much documentation, their wiki is offline). They also state that adding more servers would be a complex task. Ideally I would like to keep the existing server office running the virtual network and also run the OpenVPN daemon on the cloud and phone servers (100 Mbit and very reliable connection, respectively) so that we're on safe ground in case of a hardware failure, DSL failure, etc. So, in essence, I'm looking for a highly available OpenVPN solution (fix, patch, hack, tweak, whatever you want to call it) that will accept connections on multiple hosts (2 or more) whilst keeping the same IP address subnet regardless of the server to which you connect to. Thanks for reading and sorry for the long post, I hope it gets the point across :P

• File copying software to do this kind of work... in Windows 7 32 bit

  - by Senthil

  I need a software (Windows 7 32bit) to help me in this process: I have my documents, music, video clips, movies, pictures in my hard disk. These will not be scattered around the system. But will be inside C:\Senthil\ At the end of every week, I want to plug in an external hard disk and run a software that should make sure whatever is inside C:\Senthil\ is also present in the external disk. Files deleted from C:\Senthil\ should be deleted there, and new files should be copied etc... at the end of the process, every bit inside the source folder in my internal disk should be inside my external disk. A couple of important requirements and points: I do NOT need multiple versions or historic versions. I don't need the previous versions of my files. I only want the latest copy to be present in my "backup". Incremental backup makes sense. If files were not touched since the last backup, it need not copy. The size of my folder will run into GBs and in a year or two will go into TBs. But I will make sure the size of the external HDD is equal to or bigger than my source folder. I do not want it to run automatically because when I accidentally delete a file in my source, it will delete the one in the backup (I know this is why we have versioning facilities). I just want to be able to run it manually so that I am in control of when the backup is made and what is backed up and I should be able to pick something from the backup and restore it to the source folder in the above situation. Is there any software that will let me do exactly this? I don't want any other "smart" facility of the software to interfere with this process. I know what I want and the software can keep its smartness to itself :D The main reason I am asking this question is, I am a software developer and I can write this software myself. But I am a little constrained by time at the moment and I want to know if there is an existing program that can do this. Kindly don't worry about earthquakes or fire or snowstorms and bring up the "in case of a natural disaster your backup will also be in the damage zone and will be lost" argument because: I will have bigger things to worry about than my holiday memories. I don't think I will digitally store any life-ruining documents. This backup is only to avoid the inconvenience of obtaining a new copy of stuff that I have. Not to protect them against the end of the world. I am more worried about power surges in my area frying my system, hard disk failure, children who merrily hit Delete or teens who hit Shift + Delete or myself getting a little careless at times! In short: Is there a file/folder syncing software that listens to what I say and doesn't try to act smart? Please forgive me if I sound arrogant :)

• ISPconfig3 + CentOS 6.2 , confused on how to move forward after initial install?

  - by Damainman

  I installed ISPCONFIG3 on centos 6.2 using the great guide on howtoforge.com. Everything is up and running and I can access ISPCONFIG via a browser. However I am not sure how to move forward with the initial setup so I can setup the very first account and get my website live. Details: Only have 1 server, the centos+ispconfig is running on a virtual machine of XEN XCP. I setup the server name to be server1.mydomain.com. I only have 2 usable ips. I plan to use them as follows: xx.xx.xx.01 : For my website and the websites of all accounts I add. xx.xx.xx.02 : For ns1.mydomain.com and ns2.mydomain.com (Yea I know they should be different ips at different locations, but this is what I have to work with at the moment.... ) I registered the nameservers at my registrar with the .02 ip. I want to use bind and ISPconfig to run the DNS on my server itself and not via my registrar. Right now if I go to the .01 IP it shows the centos+apache successful install page. So to break it down basically I am not sure where to start when it comes to: (What to consider and what to do to setup the first domain on the server) Telling bind to use the name server domains with .02. Setting up my First website(which will be my main website) in ISPconfig so mydomain.com resolves properly to my server. Make it so when you go to the .01 IP, it either redirects or shows the contents of my main website. (If this can't be done, then any advice is appreciated) Making sure that when I add a new domain, it automatically puts in the proper information for the domain so it points to the right mail, database, dns, entry. If I overlooked a tutorial then please feel free to let me know, and any advice would be greatly appreciated. Some of the tutorials I found were not specific to doing everything on only one server with Centos+Apache+Bind. Right now all I did was install centos and install ISPconfig3. Trying to move forward correctly so I don't mess up everything I did by not knowing what to do. Thank you in advance!!

• Rebasing a branch which is public

  - by Dror

  I'm failing to understand how to use git-rebase, and I consider the following example. Let's start a repository in ~/tmp/repo: $ git init Then add a file foo $ echo "hello world" > foo which is then added and committed: $ git add foo $ git commit -m "Added foo" Next, I started a remote repository. In ~/tmp/bare.git I ran $ git init --bare In order to link repo to bare.git I ran $ git remote add origin ../bare.git/ $ git push --set-upstream origin master Next, lets branch, add a file and set an upstream for the new branch b1: $ git checkout -b b1 $ echo "bar" > foo2 $ git add foo2 $ git commit -m "add foo2 in b1" $ git push --set-upstream origin b1 Now it is time to switch back to master and change something there: $ echo "change foo" > foo $ git commit -a -m "changed foo in master" $ git push At this point in master the file foo contain changed foo, while in b1 it is still hello world. Finally, I want to sync b1 with the progress made in master. $ git checkout b1 $ git fetch origin $ git rebase origin/master At this point git st returns: # On branch b1 # Your branch and 'origin/b1' have diverged, # and have 2 and 1 different commit each, respectively. # (use "git pull" to merge the remote branch into yours) # nothing to commit, working directory clean At this point the content of foo in the branch b1 is change foo as well. So what does this warning mean? I expected I should do a git push, git suggests to do git pull... According to this answer, this is more or less it, and in his comment @FrerichRaabe explicitly say that I don't need to do a pull. What's going on here? What is the danger, how should one proceed? How should the history be kept consistent? What is the interplay between the case described above and the following citation: Do not rebase commits that you have pushed to a public repository. taken from pro git book. I guess it is somehow related, and if not I would love to know why. What's the relation between the above scenario and the procedure I described in this post.

• Change Logon DPI setting in Windows 8.1

  - by jmc302005

  I love how M$ keeps making decisions for me about how I want my desktop to look. Now they have added per-user dpi settings. The problem this has created is that there is no adjustable dpi setting for the Lock/Logon screen. Let me explain. you can change the dpi setting to be the same across all displays and this does affect the icons and font on the lock/logon screen. However it does not affect any app/program that can run on the lock/logon screen. Ex. I use a 44" flat screen tv for my monitor on my desktop. Big enough for me to sit in my recliner and use my comp. But I don't have a wireless keyboard. And it sucks having the wire from the keyboard running across the floor. Plus I really don't want to keep a keyboard next to me. So I use the on screen keyboard for logging in and quick typing (search, web address, etc.) So the problem is that with the new dpi setup my on screen keyboard takes up nearly half the screen. Does M$ think we are all blind? Oh no I remember they think desktops should look like tablets and phones. I tried looking through the registry to see if I could find a setting for it. In the key HKEY_USERS.DEFAULT\Control Panel\Desktop there is a string value named "LogicalDPIOverride" with a value of -1. I have a feeling this is where I can fix the issue. I tried changing the value to 0 and to 1 with no change in the result. Instead I noticed that after logging out and back in the -1 value was back in the registry. So now M$ has also added a way for us to not be able to change a setting in the registry. They are making it harder and harder for us power users to be able to do anything with the settings in windows. Soon we will all have the same exact Windows with absolutely no customization. ok sorry for the quick rant. The real question here is. How can I change this defualt dpi crap? Can I use the LogPixels string that worked for dpi in Windows 7? Here are 2 Screen shots 1 of the Lock Screen and 1 of the Logon Screen http://i.imgur.com/6RM5ufE.jpg http://i.imgur.com/cnY5bmm.jpg Please any help will be appreciated.

• Mysql Servers for Attendance System

  - by foo

  I'm building an attendance system. There are about 20 places where people will check in and check out using Mifare 1K Card. It will use MySQL as the database. The system will display something like "#ID IN: 800AM" when the first time the user checks in and "#ID OUT: 400PM" when the user checks out. For this to work, all the databases need to be synchronized with each other all the times. For an example, if user A went to location #1 to check in but by the time he wants to return home, the server at location #1 went down, he needs to go to location #2 or the nearest server to check out. The server at location #2 should display '#ID OUT: 400PM" and not "#ID IN: 400PM" since he's already checked in. So, what should I use to ensure this idea will work? My main concern is with the network (other department manages it) which is very unpredictable. It just love to go down anytime it wants to. Update LOL, didn't realize my question is not clear, just noticed it when you guys pointed it out, sorry about that. My real question is, how can I configure my MySQL to be synchronized with each other (20 servers)? MySQL cluster ? (tried reading about it, but I'm not sure if it's the right thing to do) My current setup (first phase): Local database for each server OS: Slackware A main server that keeps track which staff is at which server A web based front end for the user to see their history (which connects to the server based on their records) Main Pros No worries about network problems since it is a local database Main Cons A user can only check in and out at the same server. Databases/Servers are not connected with each others. Have to add the user to each server if the users want to check in at different locations. Which means, if he wants to go to location A, he must be checked out from location A first and then check in at location B. The server at location B didn't know that the user has checked in before at A. By the way, I've already centralized my NTP to a local server. About the network, let's just say, I don't have the authority to make changes so that the network will be better. The network won't effect all 20 servers at once, usually, just a few of them for several times a week. If there are anything else you would like me to answer, please just ask.

• Automating silent software deployments on Solaris 10

  - by datSilencer

  Hello everyone. Essentially, the question I'd like to ask is related to the automation of software package deployments on Solaris 10. Specifically, I have a set of software components in tar files that run as daemon processes after being extracted and configured in the host environment. Pretty much like any server side software package out there, I need to ensure that a list of prerequisites are met before extracting and running the software. For example: Checking that certain users exists, and they are associated with one or many user groups. If not, then create them and their group associations. Checking that target application folders exist and if not, then create them with preconfigured path values defined when the package was assembled. Checking that such folders have the appropriate access control level and ownership for a certain user. If not, then set them. Checking that a set of environment variables are defined in /etc/profile, pointed to predefined path locations, added to the general $PATH environment variable, and finally exported into the user's environment. Other files include /etc/services and /etc/system. Obviously, doing this for many boxes (the goal in question) by hand can be slow and error prone. I believe a better alternative is to somehow automate this process. So far I have thought about the following options, and discarded them for one reason or another. 1) Traditional shell scripts. I've only troubleshooted these before, and I don't really have much experience with them. These would be my last resort. 2) Python scripts using the pexpect library for analyzing system command output. This was my initial choice since the target Solaris environments have it installed. However, I want to make sure that I'm not reinveting the wheel again :P. 3) Ant or Gradle scripts. They may be an option since the boxes also have java 1.5 enabled, and the fileset abstractions can be very useful. However, they may fall short when dealing with user and folder permissions checking/setting. It seems obvious to me that I'm not the first person in this situation, but I don't seem to find a utility framework geared towards this purpose. Please let me know if there's a better way to accomplish this. I thank you for your time and help.

• Port forwarding not working properly

  - by sudo work

  I'm trying to host a small web server from my home network; however, I have not been able to successfully port forward ports to the local server. My current network topology looks like this: Cable Modem/Router - Secondary Wireless Router - Many computers (including server) The modem/router I'm using is a Cisco (Scientific Atlantic) DPC2100, provided by my ISP. The wireless router that I'm using as the central hub to my home network is a Linksys E3000. The computer being used as a server is running Ubuntu 10.04 Server Edition. The main issue is that I can't access the server remotely, using my WAN IP address. I have port forwarded my wireless router; however, I believe that I need to somehow set my modem to bridge mode. As far as I can tell though, this isn't possible. Here are the various IP address settings: DPC2100 WAN: 69.xxx.xxx.xxx Internal IP: 192.168.100.1 Internal Network: 192.168.7.0 E3000 IP Address: 192.168.7.2 Gateway: 192.168.7.1 Internal IP: 192.168.1.1 Internal Network: 192.168.1.0 Server IP Address: 192.168.1.123 Gateway: 192.168.1.1 Now I can do an nmap at various nodes, and here are the results (from the server): nmap localhost: 22,25,53,80,110,139,143,445,631,993,995,3306,5432,8080 open nmap 192.168.7.2: 22,25,80 (filtered),110,139,445 open (ports I have forwarded in the E3000)* nmap 69.xxx.xxx.xxx: 1720 open *For some reason, I can SSH into the server at 192.168.7.2, but not view the website. Here are also some other settings: /etc/hosts/ 127.0.0.1 localhost 127.0.1.1 servername ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters /etc/apache2/sites-available/default snippet <VirtualHost *:80> DocumentRoot /srv/www/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> ... </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> ... </Directory> ErrorLog /var/log/apache2/error.log LogLevel warn CustomLog /var/log/apache2/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> ... </Directory> </VirtualHost> Let me know if you need any other information; some stuff probably slipped my mind.

• My network drive disappears from Mac OS Finder

  - by Mariusz

  I have recently bought a Netgear WNDR3800 router to use it in my home network. But just the same day I installed it, I noticed a strange behaviour of Finder and iTunes. Let me explain it further. There is a Synology DS111 NAS attached to that router and two Macs with Mac OS X Lion. One of them is connected by a cable and the second one wirelessly. Before I changed my router to the new one I mentioned above, Finder always used to display my NAS on its sidebar. So I could just click its network name to access shared folders existing on it. But after I installed WNDR3800, I can no longer access the NAS that way. It is no longer displayed. I always have to mount it manually by typing its IP address using the Finder's 'connect to server' option. The same NAS supports TimeMachine backups and has an inbuilt DLNA server. And the same situation here. I can't perform a backup because my NAS is no longer accessible in TimeMachine preferences. iTunes does not display it as well (as a multimedia server) even though it used to before I installed that router. What's important, everything works fine for a couple of minutes after I restart the router or the NAS. Or even when I change the NAS's IP address it becomes accessible again in Finder, TimeMachine and iTunes, but only for some time. Both the Mac computers I mentioned behave the same way. And all those issues have been taking place sice I installed that new router. Before I did that, everything had worked fine. My old router was Netgear WGR614v10. Would you be so kind to tell me what you think could possibly be the reason of that behaviour? What settings of the router should I look closer at? I'm not a network specialist, but is it possible that some network packets are blocked for some reason? I will be grateful for any clues you give me. Thank you.

• NIC is receiving, but not transmitting at all?

  - by Shtééf

  I'm trying to fix a very strange problem remotely on a machine at a customer site. The machine is a Dell PowerEdge, I believe a 1950 (haven't verified, but the lspci output matches specs I found.) The machine has two similar NICs, identified as Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) by lspci, and using the bnx2 driver. (I suspect these are on-board and on the same controller, which is what I'm accustomed to for this type of machine.) The primary interface eth0 works perfectly, and is in fact how I am ssh'd in. However, the secondary interface eth1 is not transmitting. I can see this in ifconfig output, for example, where the TX field is always 0. However, it is receiving, and tcpdump shows ARP requests coming from the ISP's gateway on the other side. The interface is physically connected to a Siemens BSTU4 modem, configured by the ISP. The link is properly set to 10MBps and full duplex, without negotation, as the ISP requested. A small /30 subnet is configured. For the sake of anonimity, let's say the machine is 3.3.3.2/30, and the ISP's gateway .1. The machine has no firewall settings whatsoever. Even running something like arping -I eth1 3.3.3.1, and running tcpdump alongside, shows no traffic whatsoever being transmitted on the interface. (But the other side keeps steadily sending ARP requests, and that is all that can be seen.) What could be causing this? Here's some output, anonymized, which may hopefully help: $ ethtool eth1 Settings for eth1: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: Not reported Advertised auto-negotiation: No Speed: 10Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: off Supports Wake-on: d Wake-on: d Link detected: yes $ ip link show eth1 3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:15:c5:xx:xx:xx brd ff:ff:ff:ff:ff:ff $ ip -4 addr show eth1 3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 inet 3.3.3.2/30 brd 3.3.3.3 scope global eth1 $ ip -4 route show match 3.3.3.0/30 3.3.3.0/30 dev eth1 proto kernel scope link src 3.3.3.2 default via 10.0.0.5 dev eth0

• Multiple OS's and GRUB chainloading

  - by Kent

  Hi, I want to have multiple OS installations and I have been advised that chain loading using GRUB is a good way to handle this. I have looked at tutorials on the web but I still have some questions before I can start. I want: Windows XP: 20 GB. For running some school stuff and a game which does not work through WINE. Xubuntu 9.04: 85 GB. My main OS. Another Linux distribution: 15 GB . For experimenting and trying Linux distributions out. I will: Wipe and install various distributions quite often on the 15 Use dd to make a copy of my Windows partition after installing it and getting things to work as I like. My experience is that Windows needs to be re-installed maybe once per year to not get bloated and slow. I have been told: To use GRUB chain loading. It will make it easier when kernel upgrades are made in the Linux distributions, as they modify the GRUB boot-menu. To my understanding I need to: (I might very well be mistaken) Install Windows first. Then install Xubuntu and let it write over the MBR with GRUB (I guess this is the default). Get the GRUB on the MBR start Windows XP if I want to (it's done by default), start Xubuntu using the kernel of my choice or defer execution to the boot sector of my other Linux distribution. The actual chain loading will only occur when I want to start my experimental install of Linux. I wonder: Is step 3 above correct and a good way to handle this? Is it also a good way to use chain-loading for both Xubuntu and my experimental Linux installation? How do I get a Linux distribution to install the boot loader it comes with to the boot sector of its partition and not to the MBR? If I can't get it to not touch the MBR. Then I could make a backup of the MBR using dd and then write it back after installing my experimental Linux installation. But then, how would I get the boot loader (lets say GRUB) into the boot sector of the experimental Linux installation? How would it work if said Linux installation gets a new kernel update and needs to update the GRUB menu?

• How to Configure Source NAT (Private IP => Public IP Outbound)

  - by DavidScherer

  I'm running VMWare ESXi Free and have Zentyal SBS 3.2 running as a Gateway. I have 5 Public IPS (CIDR/29, let's call them 69.1.1.1 - 69.1.1.5) and currently Zentyal is bound to 69.1.1.1 as the Gateway, with the other 4 Public IPs set as Virtual Interfaces in Zentyal (wan2-wan5) I have machines sitting on the Private Network (10.34.251.x) that, when going Outbound (to Google for instance) should be seen by the Internet as an IP other than the Gateway (69.1.1.1), this is because our machines need to be able to communicate with 3rd party APIs that expect these requests to come from a specific IP. From what I could find, SNAT (Source NAT) in Zentyal is used to achieve this, but I'm not sure how to configure it and cannot find a specific piece of Documentation for it at Zentyal. I've tried setting this up a couple different ways, with no results and at this point I have no idea if I'm going about this completely wrong, or my lack of experience with networking and the associated terminology is preventing me from placing the correct values in the correct fields. I get the following form to set up "SNAT" rules in Zentyal: Perhaps someone can offer some guidance and definitions for the fields above? SNAT Address Is this the Public IP I want to masquerade? Outgoing Interface Should this by my External NIC (one connected to Public 'Net), or is it the "Private" interface? It sounds as though this should be the External interface as I want the traffic from the internal network sent Out over this Interface (using a different IP than normal, anyway) Source Is the the Source on the internal network (one of the private IPs?), a public IP I want to masquerade as, or something else entirely? Destination Is this a place on the Internet (eg, "Only do this for the Site Google.com"/IP) or am I allowing myself to become confused again? Service I'm assuming this allows me to restrict which services this rule will apply to, but is it for a service on the internal network or a service being accessed on the external network? If I can offer any further details or information to make what I'm trying to do more clear, I will happily do so. Honestly any kind of help here would be very appreciated. I'm not a NetOps or anything even close, I spend most of my day writing code and my entire "team" at this company consists of "me, myself, and I" so while I try to broaden my KB at every possible opportunity, I can only learn so much, so fast and I feel like with networking especially there's just so much, coupled with a learning curve for each solution that likes to (from my limited perspective) use slightly different terminology that what I'm used to (and I don't exactly have the necessary experience to cross reference this stuff with the stuff I already know in context).

• Second HDD not seen by Windows 7 on Dell Xps l501x

  - by George

  I have a Dell XPS Laptop (l501x). I have replaced the original Seagate 500GB hard drive with an SSD Intel 320 120GB when I first purchased it a year ago. It's been working great. The laptop is booting in about 23 seconds, so the SSD is great. I have an Acronis image created that I came back to every three months just to keep everything clean. The SSD is partitioned with one logical drive for my data. So, recently I thought since I am not using my optical drive often enough to swap it out with a HDD caddy and add my seagate 500gb hard drive. I ordered the caddy placed the HDD in it and now load Windows. It just hangs on the screen that should show the Windows logo. I have tried everything that I know and searched it online. I have uninstalled the SATA controller AHCI and let Windows install it. Still will not boot into windows. I wanted to mention that the Seagate 500GB drive was the one that came with my laptop before I switched to the Intel SSD. As you know Intel has this application called Intel Rapid Technology which loads once in a while and shows the second hard drive, but then, when I restart it hangs again and Windows will not load. As soon as I remove the HDD Caddy and restart it loads Windows fine. I also formated the Seagate 500GB HDD in NTFS and still Windows will not load. When I go into the BIOS it shows the Fixed SSD and also "Sata ODD 500GB" instead of the optical drive but it will not boot into Windows when the HDD caddy is present. There is nothing wrong with the caddy. I have another laptop (Asus) and I installed the HDD caddy and Windows 7 loads without any glitch. I don't get it. I have also flashed the BIOS because Dell had a new version (A08). I also wanted to add that I refreshed Disk Management and the Device Manager and the second drive does not display. At this point I think it's a Windows issue so before I reinstall Windows 7 Home Premium from scratch I wanted to see if there was anything I was missing. Any advice would be greatly appreciated.

• One user sometimes gets an unknown certificate error opening Outlook

  - by Chris

  Let me clarify a little. This isn't an unknown certificate error it's an unknown certificate error in so much as I can't figure out where the certificate comes from. This happens on a Win 7 Enterprise machine connecting to Exchange 2010 with Outlook 2010. The error he gets is that the root is not trusted because it's a self-signed cert. Take a look at this screenshot because even if I had generated this myself I wouldn't have put "SomeOrganizationalUnit" or "SomeCity" or "SomeState", etc. (Red block covers our domain name.) I'm a little concerned this is a symptom of a security breach. Exchange 2010 has three certificates installed but none of them are this certificate. They all have different expiration dates (one is expired) and different meta-data. edit: There are two scenarios that I see the certificate warning and one of them I can reliably repeat. When the user leaves his computer on over night Outlook pops the Security Warning window. I don't know what time this happens. Using Outlook Anywhere if I connect to Exchange externally via a cellular USB modem the Security Warning window will appear every time I close and reopen Outlook. Whether I say Yes or No does not make a difference on whether or not I can connect to Exchange and send/receive email. In other words, I can always connect to Exchange. I've checked my two Exchange servers and my Cisco router for a certificate that matches this one and I can't find it. edit 2: Here is a screenshot of the Security Alert window. (I've been calling it Security Warning... My mistake.) edit 3: I stopped seeing this error several weeks ago but I can't tie it to any single event (because I just sort of realized that warning had stopped showing up) but I think I found the source of the certificate. Last week I found out that the certificate on our website DomainA.com was invalid. I knew that our web admin had installed a valid certificate so when I look into the problem I found out I was being presented with the invalid certificate that this posting is in regards to. The Exchange server's domain is mail.DomainA.com so I can only guess that Outlook was passing this invalid certificate through as it did some kind of check on DomainA.com. This issue is still a mystery because the certificate warning stopped appearing several weeks ago whereas the invalid certificate issue on the website was only fixed last week. It ended up being a problem with the website control panel. The valid certificate was installed but not being served for some reason and instead the self-signed cert was being served.

• mixing different technologies using ARR reverse proxy

  - by Jaepetto

  I'm currently trying to put together a proof of concept on mixing various technologies onto one web site in order to ease migrations and add flexibility. The idea is to create one 'mashup' site behind an IIS 7.5 ARR reverse proxy. For the time being the ARR reverse proxy forwards all request to our main site. The request are as follow: client -> ARR: Get / ARR -> Server 1: Get / Server 1 -> ARR: 200: /index.htm ARR -> client: 200: /index.htm ...so far so good. Let's say, I want to add a new site (root of another server) as a subsite of my main website. a simple inbound rule does the trick: <rule name="sub1" stopProcessing="true"> <match url="^mySubsite(.*)" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false" /> <action type="Rewrite" url="http://server2/{R:1}" /> </rule> The requests now are: client -> ARR: Get /mySubsite ARR -> Server 2: Get / Server 2 -> ARR: 200: /index.htm ARR -> client: 200: /index.htm ... still ok. The issue comes when the site on server2 sends a redirection (e.g. to a login page). In the case of SharePoint, it will redirect the user to: /_layouts/Authenticate.aspx?Source=%2F ...which does not exists: client -> ARR: Get /mySubsite ARR -> Server 2: Get / Server 2 -> ARR: 301: /_layouts/Authenticate.aspx?Source=%2F ARR -> client: 301: /_layouts/Authenticate.aspx?Source=%2F client -> ARR: Get /_layouts/Authenticate.aspx?Source=%2F ARR -> client: 404: Not Found Does anyone know a way write the outbound rule to rewrite the response from server 2 "301: /_layouts/Authenticate.aspx?Source=%2F" to "301: /mySubsite/_layouts/Authenticate.aspx?Source=%2FmySubsite%2F"?

• What Sort of Server Setup Am I Likely to Need? - School A/V streaming

  - by DeathMagus

  My prior experience with servers has generally been limited to home file-sharing servers, low-traffic web-servers, and the like. This leaves me with the technical knowledge of how to set up a system, but little experience in terms of scaling said system. My current project, however, has me as the technical lead in setting up a school for online audio and video streaming. The difficulty I'm running into is that I don't quite have the experience to guess what they'll need, and they don't have the experience to tell me - so I've tried to ask as many pertinent questions about what they want to do with their server, and here's what I found out: About 1000 simultaneous users, and hoping to expand (possibly significantly) Both video and audio streaming, at obviously the highest quality possible Support for both live and playlist-based streaming. Probably only one channel, but as it's an educational opportunity, I imagine letting them have a few more wouldn't hurt. No word on whether they're locked into Windows or whether Linux is acceptable. Approximate budget - $7000. It may actually be about $2k less than this, because of a mishap with another technology firm (they ordered a $7000 DV tape deck for some reason, and now the company wants them to pay a 30% restocking fee). The tentative decisions I've already made: I'm planning on using Icecast 2 for my streaming server, fed by VLC Shoutcast encoding. Since the school already has a DMZ set up, I plan on placing the Icecast server in there, and feeding it through their intranet from a simple workstation computer in their studios. This system isn't in any way mission critical - it's an education tool (they're a media magnet school), so I figure redundancy is not worthwhile to them from a cost:benefit perspective. What I don't know is this: How powerful of a server will I need? What is likely to be my major throttle - bandwidth? How can I mitigate that? Will I need anything special for the encoding workstation other than professional video and audio capture cards and a copy of VLC? Are there any other considerations that I'm simply missing? Thanks a lot for any help - if there's more information you need, let me know and I'll tell you all I can.

• Frequent and weird wifi disconnections

  - by Sidou

  How would you explain, troubleshoot (and solve) the following problem? Wifi ADSL modem router D-link 2640R installed in living room at about 1.8m height. Working fine, synchronising and getting/serving stable internet connection. First situation: -Laptop 01 in other end of the house, let's say in room01 southern to the living room, distant by about 15m. Getting stable signal of good to very good quality. No disconnection. -Laptop 02 in room02 opposite to room01 (5m West) which makes it almost at the same distance and direction from the router located 15m North. Getting stable signal of good to very good quality. No disconnection. Second situation: -Laptop 01 moved to room03 Northern to the living room (actually just 3m behind the wall where the router lies). Getting stable signal of excellent quality. No disconnection. -Laptop 02 still in room02 but now experiences frequent disconnections (actually almost impossible to get the Internet even though the signal level is still very good. Either no Internet with the wifi icon appearing connected to access point or no connection established at all which happens every 2 minutes and that means virtually no Internet at all as I can just get a timeframe of 1 minute or so to load any website or even get to the router's web based control panel. If Laptop 01 is completely shut down or its wifi adapters shut down or even still working but its wifi MAC address forbidden, then Laptop 02 has no problem at all. If Laptop 02 is moved to a nearer location to the router, in the living room for instance, then no connection problem occurs even if Laptop 01 is also connected. And also if we move back Laptop 01 to its original location (room 01), then no problem as well. I'm completely lost and don't know how to address this issue. I tried to change the Wifi channel and even tried the auto channel scan but that didn't solve it. I know that the problem is probably coming from Laptop 01 being in its new location or some sort of interference as the problem occurs only under the described condition but I have no idea how to solve it! I also scanned the neighborhood for wifi jam using InSSIDer, there are few other access points but they don't seem to affect the situation. Any ideas about the steps to follow or tools to use ?
