• Why do I have to log into hotmail twice?

  - by Tony Lee

  I just recently noticed I have to attempt a login into hotmail twice before it succeeds. Although I'm using Google Chrome (3.0.195.21), the symptoms are well described in a Mozilla thread. In short, I'm told: The e-mail address or password is incorrect. Please try again. The thread on mozilla's site that supposed to describe the latest details (and the 1st hit on google when I search for "hotmail login twice") requires an account to read so I'm hoping someone here has a good synopsis of what the cause is. I normally start at hotmail.com, which redirects to login.live.com/.... I can login by starting at mail.live.com, using IE8 or attempting a 2nd login. Oddly, if I start at login.live.com Chrome tells me there is a redirect loop. Does anyone know or have a public link to the root cause of the double login? (it is a hotmail account I'm login into) EDIT - Caused by my 'restricting how 3rd parties can use cookies'. If I allow all cookies, it works first time.

• Broken Python installation on CentOS 5.8

  - by Beckett

  I already searched for solution to my problem via Google and stackoverflow's search facility, but haven't found anything related specifically to it. Here's the problem: I needed python 2.7.3 on CentOS 5.8 machine which has only python 2.4.3 preinstalled. Also neither there's the suitable version in it's repositories nor I can upgrade installed version. That's why I decided to build python from source code. But I've made a mistake: instead of make altinstall I did make install thus changing default version of the current installation. It was before I found this article - How to install Python 2.7.3 on CentOS 6.2 . I guess 5.8 and 6.2 versions aren't different to the extent this article is inapplicable. After installation of new python version I installed pip, but once I tried to invoke it, I got "No module named pkg_resources" error. In order to solve this issue I installed setuptools from repository. But it had only led to another error: "Distribution Not Found". My final step was to follow the guide I posted the link to, but I was unable to perform last step: easy_install-2.7 virtualenv command threw "-bash: /usr/local/bin/easy_install-2.7: .: bad interpreter: Permission denied" error. Now when I try to invoke pip or pip-2.7 both commands raise the same error with different names of binaries after "-bash:". Is there any way to fix this problem, so I could install new python version (2.7.3) alongside with the preinstalled one (2.4.3) according to the guide? Any help will be appreciated. P.S.: yum is working fine, although it needs python to function, so I hope the damage I unknowingly caused isn't very severe. Also I'm not a native English speaker, so I apologize for possible occasional grammatical and/or spelling errors.

• How can I preview the contents of books sold on Amazon in Internet Explorer 10?

  - by Aceman

  I run 64-bit Windows 7 and have both Internet Explorer 10 and a newly-downloaded copy of Google Chrome. I downloaded the latter when I found that I could not look (preview) the contents of books sold on Amazon (using it "Look Inside" feature) and wanted to try to get a handle on how extensive the problem was (i.e., whether it occurred on other browsers, too). It turns out that this isn't a problem with Chrome. However, I have grown accustomed over the years to IE and would prefer to resolve this problem instead. Here's an example of my attempt to 'Search Inside' a book on sale at Amazon: http://www.amazon.com/Intellectuals-Race-Thomas-Sowell/dp/0465058728/ref=sr_1_1?s=books&ie=UTF8&qid=1382301764&sr=1-1&keywords=thomas+sowell#reader_0465058728 I understand that I can't (as is the case in some technical support websites) add a screen shot (ie. JPG to this), but if I were to describe what this looks like in IE, the area where the text would appear appears as a blank white page with horizontal lines where the text would ordinarily be. I have just examined this posting of mine via Chrome and the contents of the selected page are clearly visible.

• VMware "boot screen" - add info like contact, phone number, etc.?

  - by TheCleaner

  I've tried searching Google and VMware's KB but maybe I'm not typing the right search criteria...only finding ways to fix problems with booting or screen issues. On the default boot screen of a host it looks similar to this picture from GIS: I'm curious if it is possible somehow to make it look like this instead (adding custom details): I know for the most part the info is "useless" since it is administered remotely, etc. But when I deploy standalone hosts to branch offices, it'd be nice for them to see this type of info on the boot screen. I may also include the VMs hosted on it (again on standalone hosts). Normal monitoring, etc. will be done remotely. This is strictly for odd times when the branch contact may say "the electricians are saying they need to turn off this circuit but I have no idea who to call in IT to tell them this box needs to be shut down" or similar. Anyone who has dealt with small branch offices can tell you that if it isn't labeled they easily forget what it is for and will simply say after the incident "I didn't know what it was or who to call." Possible?

• Finding matching columns in excel

  - by fakaff

  I've never used excel before so I need the simplest solution available, and this is a work assignment due this week so I didn't have time read much of the documentation. Basically, I have two tables, A and B, and they are both thousands of rows long. Description of my task: right now (since I don't know better) I'm manually doing this: Go to row i in table B. Select entries in columns B(a, b, c) of that same row. Look for a row in table A where column A(b) matches row B(a). Paste the entries of columns B(a) of row i at the end of the row found in the last step. Repeat for row i + 1. Example: row B(cat, dog, mouse) matches A(mammal, cat, Mr. Whiskers). So I would paste B after A and have A(mammal, cat, Mr. Whiskers, cat, dog, mouse). Note: I am not joining tables. I am merely extending table A by pasting row A(b) if row A(b) matches row B(a). Also, sometimes entries are spelled slightly differently. Using wildcards to search for candidates would be of help. As the description should let on, this task is very tedious and inefficient if I don't know how to automate some operations (there are thousands of entries). Any quick tips as to how to be more productive is a big help.

• saving and searching encrypted mail

  - by student

  I often send and receive gpg-encrypted mail. At the moment I use thunderbird + enigmail (in linux) to do that. As far as I know there is no way in thunderbird to find all encrypted messages which bodies contain particular keywords. There also seems to be no option to save encrypted mails decrypted (so they would be searchable). However for me it is important to be able to search old encrypted mails. So my question is: Is there a way in linux to save incoming mails automatically decrypted in my inbox and save outgoing encrypted mail decrypted in the send folder? Both times adding a line to the body which remarks that the mail was encrypted. It could be another email client for linux that could to that or perhaps a solution using procmail or maildrop. For a procmail solution I guess there could be some problems with encoding (perhaps one have to use emil?) the solution should work well with german special characters in subject and body. Note that the solution should work for multipart encrypted messages (including encrypted attachments) too i.e. with everything which could thunderbird + enigmail generate. Further note that I don't want a discussion about security holes. For me it's ok if messages are stored decrypted on my harddrive (which is encrypted as a whole anyway). In doubt for a first solution it would be ok to store my private key passphrase in cleartext on my harddrive, too. The point is that the mails are encrypted on the mailserver or more generally on their "way through the net".

• AJP Connector Apache-Tomcat with php and java application

  - by Safari

  I have a question about proxy and ajp module. On my machine I have a Apache web server and a Tomcat servlet container. On Tomcat is running a my java webapplication. On Apache I have some services and I can call these in this way: http://myhos/service1 http://myhos/service2 http://myhos/service3 I would configurate a ajp connector to call my tomcat webapplication from Apache. I would somethin as http://myhost to call the Tomcat webapp. So, I configurated my apache in this way..and I have what I wanted: I can use http://myHost to visualize the Tomcat webApp by Apache. <VirtualHost *:80> ProxyRequests off ProxyPreserveHost On ServerAlias myserveralias ErrorLog logs/error.log CustomLog logs/access.log common <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /server-status !

• Failing to load rootfs: Ubuntu 10 + grub2 + rootfs ext4 w/ RAID1

  - by James

  I am having problems booting a new Ubuntu 10 (server) install.

If I ls (md2)/ it properly lists all the files on the RAID1 filesystem (ext4) so it doesn't appear to be an issue accessing the raid device. Does anyone have any suggestions as to what the problem might be? I can't figure this one out.

• Tools for displaying a multidimensional data table?

  - by ShreevatsaR

  [Apologies if this sort of question is off-topic for SuperUser. Please redirect to the right place if so.] There is a 3-dimensional array of values. (That is, instead of a table/2-dimensional array with values in a grid, the values can be thought of in a cube instead.) Is there a way to display this "cube" interactively, ideally on a webpage? Specifically, given the data, it would work something like this: the user selects two of the 3 variables. He then sees a "stack" of tables, one for each value of the third variable (cross-sections, in other words). By selecting the appropriate table from the stack, he can see the (i,j,k) value he wants. The "technology" for displaying such a thing (stacked tables, rotation, etc.) already exists, so this seems the sort of thing that someone ought to have written already. To be clear: I don't need sophisticated graphics necessarily, just the ability to select from cross-sections of variables. But I have no experience with (say, for displaying on a webpage) what web gadgets exist, so I'm clueless how to even search for one. (Google searches like "multidimensional data visualization" didn't throw up anything useful. Google Spreadsheets can do a few kinds of charts which can be embedded on a webpage, but I cannot tell if this is one of them.) [I can imagine how it ought to work for higher dimensions. For four-dimensions, instead of selecting just a stack, you'd first select an (i,j) from an "outer table", which would show all (k,l) values for that (i,j). For higher dimensions, inductively: you select (i,j), and then repeat what you'd do with 2 fewer dimensions.] So has this been written? Is this easy to write? Where ought one to look for such a thing?

• Graphite not running

  - by River

  I'm currently trying to install graphite 0.9.9 on a gentoo box using these instructions from the graphite wiki. Essentially, it fronts graphite using apache and mod_wsgi. Everything seems to have gone well, except that apache / the graphite webapp never seem to return a response to the web browser (the browser continuously waits to load the page). I've turned on the graphite debug info, but the only message in the log files is this, repeated over and over again in info.log (with the pid always changing): Thu Feb 23 01:59:38 2012 :: graphite.wsgi - pid 4810 - reloading search index These instructions have worked for me before to set up graphite on an Ubuntu machine. I suspect that mod_wsgi is dying, but I have confirmed that mod_wsgi works fine when not serving the graphite webapp. This is what my graphite.conf vhost file looks like: WSGISocketPrefix /etc/httpd/wsgi/ <VirtualHost *:80> ServerName # Server name DocumentRoot "/opt/graphite/webapp" ErrorLog /opt/graphite/storage/log/webapp/error.log CustomLog /opt/graphite/storage/log/webapp/access.log common # I've found that an equal number of processes & threads tends # to show the best performance for Graphite (ymmv).

• How can I get web pages from sub.a.com using url sub.b.com?

  - by Steven

  I have developed www.mysite.com. This site can be "integrated" into my partners website. What I do is to create partner1.mysite.com and repalce my header and footer with my partners header and footer and replace some CSS styling. This should make it as transaprent as possible for the user, so that they think they are still browsing my partners website. There are two ways I see how I can accomplish this: 1. My partner uses an IFrame to show the content from partner1.mysite.com 2. My partner creates sub domain and points it to my sub domain. Solution 1 is easy, but I'm not sure how search engines likes this, so I will try solution 2. QUESTION Can I use mysite.partner1.com but read content from partner1.mysite.com? I don't want to forward / redirect users to partner1.mysite.com. It's important that the URL is mysite.partner1.com / mysite.partner1.com/some/page. Is this possible? For testing, I have Apache configuration more or less like this: NameVirtualHost 10.0.0.17 <VirtualHost 10.0.0.17> DocumentRoot D:/wamp/www/mysite/ ServerName mysite.com </VirtualHost> <VirtualHost 10.0.0.17> DocumentRoot D:/wamp/www/mysite/ ServerName site1.mysite.com </VirtualHost> // Since this is on my localhost, I also configure site1 here <VirtualHost 10.0.0.17> DocumentRoot D:/wamp/www/site1/ ServerName site1.com </VirtualHost> <VirtualHost 10.0.0.17> ServerName mysite.site1.com --> DO SOME SORT OF FORWARDING HERE <-- </VirtualHost>

• Apache Probes -- what are they after?

  - by Chris_K

  The past few weeks I've been seeing more and more of these probes each day. I'd like to figure out what vulnerability they're looking for but haven't been able to turn anything up with a web search. Here's a sample of what I get in my morning Logwatch emails: A total of XX possible successful probes were detected (the following URLs contain strings that match one or more of a listing of strings that indicate a possible exploit): /MyBlog/?option=com_myblog&Itemid=12&task=../../../../../../../../../../../../../../../proc/self/environ%00 HTTP Response 200 /index2.php?option=com_myblog&item=12&task=../../../../../../../../../../../../../../../../proc/self/environ%00 HTTP Response 200 /?option=com_myblog&Itemid=12&task=../../../../../../../../../../../../../../../proc/self/environ%00 HTTP Response 301 /index2.php?option=com_myblog&item=12&task=../../../../../../../../../../../../../../../proc/self/environ%00 HTTP Response 200 //index2.php?option=com_myblog&Itemid=1&task=../../../../../../../../../../../../../../../proc/self/environ%00 HTTP Response 200 This is coming from a current CentOS 5.4 / Apache 2 box with all updates. I've manually tried entering a few in to see what they get, but those all appear to just return the site's home page. This server is just hosting a few Joomla! sites... but this doesn't seem to be targeting Joomla (as far as I can tell). Anyone know what they're probing for? I just want to make sure whatever it is I've got it covered (or not installed). The escalation of these entries has me a bit concerned.

• setting up tracd behind mod_proxy?

  - by FilmJ

  I'm having trouble setting up mod_proxy and tracd. Seems almost all the search results for this problem take me to the built-in trac documentation page that mentions it as an option. I have several VirtualServers already running on the box in question, so running tracd on port 80 or 443 is not an option, but I do want to make my trac server accessible on this machine without exposing an additional port via the firewall. Making things even more complicated is that I have multiple trac repositories being served by the same instance of tracd, and so I want to set it up so: http://trac.abc.com is proxy'd to localhost:8000/projects/abcproject, and http://trac.def.com is proxy'd to localhost:8000/projects/defproject. Currently, the setup I have below results in 100% 403 errors. The server is running as www-data and the directory where all trac files are stored is owned by www-data, AND tracd (as show below) is running as www-data, so not sure where it's getting hung up. The relevant configuration on /var/apache2/sites-enabled/trac.abc.com: ProxyPass / http://localhost:8000/abcproject ProxyPassReverse / http://localhost:8000/abcproject The relevant configuration on /var/apache2/sites-enabled/trac.def.com: ProxyPass / http://localhost:8000/defproject ProxyPassReverse / http://localhost:8000/defproject The command used to instantiate tracd: tracd -a defproject,/var/www/vhosts/trac-common/users.htdigest,DEFProject -a abcproject,/var/www/vhosts/trac-common/users.htdigest,ABCProject -p 8000 -b localhost -e /var/www/vhosts/trac-common/projects If I access the site at http://localhost:8000/ everything works fine, but if I try to access via any of the proxy'd hosts I end up with 403 at every turn. I've used mod_proxy successfully as described above for other servers, such as couchdb, so maybe this has to do with the headers sent by tracd??

• Squid not caching files (Randomly)

  - by Heinrich

  I want to use an intercepting squid server to cache specific large zip files that users in my network download frequently. I have configured squid on a gateway machine and caching is working for "static" zip files that are served from an Apache web server outside our network. The files that I want to have cached by squid are zip files 100MB which are served from a heroku-hosted Rails application. I set an ETag header (SHA hash of the zip file on the server) and Cache-Control: public header. However, these files are not cached by squid. This, for example, is a request that is not cached: $ curl --no-keepalive -v -o test.zip --header "X-Access-Key: 20767ed397afdea90601fda4513ceb042fe6ab4e51578da63d3bc9b024ed538a" --header "X-Customer: 5" "http://MY_APP.herokuapp.com/api/device/v1/media/download?version=latest" * Adding handle: conn: 0x7ffd4a804400 * Adding handle: send: 0 * Adding handle: recv: 0 ... > GET /api/device/v1/media/download?version=latest HTTP/1.1 > User-Agent: curl/7.30.0 > Host: MY_APP.herokuapp.com > Accept: */* > X-Access-Key: 20767ed397afdea90601fda4513ceb042fe6ab4e51578da63d3bc9b024ed538a > X-Customer: 5 > 0 0 0 0 0 0 0 0 --:--:-- 0:00:09 --:--:-- 0< HTTP/1.1 200 OK * Server Cowboy is not blacklisted < Server: Cowboy < Date: Mon, 18 Aug 2014 14:13:27 GMT < Status: 200 OK < X-Frame-Options: SAMEORIGIN < X-Xss-Protection: 1; mode=block < X-Content-Type-Options: nosniff < ETag: "95e888938c0d539b8dd74139beace67f" < Content-Disposition: attachment; filename="e7cce850ae728b81fe3f315d21a560af.zip" < Content-Transfer-Encoding: binary < Content-Length: 125727431 < Content-Type: application/zip < Cache-Control: public < X-Request-Id: 7ce6edb0-013a-4003-a331-94d2b8fae8ad < X-Runtime: 1.244251 < X-Cache: MISS from AAA.fritz.box < Via: 1.1 vegur, 1.1 AAA.fritz.box (squid/3.3.11) < Connection: keep-alive In the logs squid is reporting a TCP_MISS.

• Replacing DropBox with: Amazon S3 + SSL + GPG/TrueCrypt + Mounting on OSX ??

  - by Matt Rogish

  So, right now we're using DropBox to share various data files around between approximately 10 Mac OS X systems. However, we already have an S3 account and everyone on the lowest DropBox plan of $10/mo seems too expensive. So, I am contemplating something that would allow us to replace DropBox with our own home-grown solution. We are all fairly technical people and/or smart enough to follow some steps, so if it's not as "user friendly" as DropBox we're all comfortable with that. There are plenty of docs out there that have bits and pieces of what I want but some of the tools don't seem to fit the requirements: Transport security via SSL to the bucket Encryption of bucket contents Bi-directional syncing Most of the scripts I can find on the internet use "duplicity" which appears to fail #1 (it doesn't look like duplicity supports SSL to S3 - the docs don't state but the protocol looks plain old http http://www.nongnu.org/duplicity/duplicity.1.html#sect6 ) Many scripts use gpg to encrypt files. This seems like it could work, however I have to make sure that each OSX client is able to use the same key to encrypt and decrypt files (key management is left to me to manage). Finally, most of the scripts use one-way replication, e.g. using Amazon S3 as a simple backup store. As we'd be using Amazon S3 as the "repository" they fail this one. Whew. So, I'd love a single tool that does this but after an exhaustive search I don't think one exists. I'd be happy just knowing which tools out there can fulfill my 3 requirements, after that I can stitch together the rest. Any thoughts? THANKS!

• 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?

• Redirect 301 fails with a path as destination

  - by Martijn Heemels

  I'm using a large number of Redirect 301's which are suddenly failing on a new webserver. We're in pre-production tests on the new webserver, prior to migrating the sites, but some sites are failing with 500 Internal Server Error. The content, both databases and files, are mirrored from the old to the new server, so we can test if all sites work properly. I traced this problem to mod_alias' Redirect statement, which is used from .htaccess to redirect visitors and search engines from old content to new pages. Apparently the Apache server requires the destination to be a full url, including protocol and hostname. Redirect 301 /directory/ /target/ # Not Valid Redirect 301 /main.html / # Not Valid Redirect 301 /directory/ http://www.example.com/target/ # Valid Redirect 301 /main.html http://www.example.com/ # Valid This contradicts the Apache documentation for Apache 2.2, which states: The new URL should be an absolute URL beginning with a scheme and hostname, but a URL-path beginning with a slash may also be used, in which case the scheme and hostname of the current server will be added. Of course I verified that we're using Apache 2.2 on both the old and the new server. The old server is a Gentoo box with Apache 2.2.11, while the new one is a RHEL 5 box with Apache 2.2.3. The workaround would be to change all paths to full URL's, or to convert the statements to mod_rewrite rules, but I'd prefer the documented behaviour. What are your experiences?

• Looking for way to log process terminations on OS X (Mac)

  - by Stan Sieler

  I'm looking for a way to log all process terminations on my Mac (OS X 10.6.8). (And see pid, timestamp, process name) I've implemented something similar for HP-UX, but it required a kernel-level driver and intercepting several variations of "exit()" (the normal one, and the one invoked on behalf of a process while it's aborting). Why do I want the info? I've been seeing messages in my system log file (dmesg) like: CODE SIGNING: cs_invalid_page(0x1000): p=91550[GoogleSoftwareUp] clearing CS_VALID CODE SIGNING: cs_invalid_page(0x1000): p=92088[GoogleSoftwareUp] clearing CS_VALID Although dmesg lacks timestamps, apps/Utilities/Console : Database : all : search for CS_VALID shows that the messages appears about once every 58 1/2 minutes. I suspect the number after "p=" is a process id (pid) ... but for a process that has long since terminated by the time I see the message. So, if there was a process termination log mechanism that recorded the pid, the time of termination, the reason for termination, and the process name (at time of termination), that would probably allow me to determine who's causing those errors to be logged! (No, I'm not running Chrome on my Mac, and "ps -ef | grep -i goog" gets no hits either ... I'm not consciously running any Google apps on the Mac) thanks, Stan [email protected]

• Why are certain folders in my XP network share really, really slow?

  - by bikefixxer

  I have a workgroup set up with Windows XP. My file "server" is running XP Pro and the clients are running XP home. I've turned simple file sharing off on the server because certain clients need access to certain folders and not to others, and I want to keep it that way. Therefore, I've used the granular sharing/security settings to enable certain clients access to certain folders. I'm using the net use command in a batch file on the clients to add the share when they logon so it's always available via a mapped drive or a shortcut. On some clients "My Documents" points to the mapped drive, but all of the local and application settings stay local. Everything works well except for accessing a certain folder on the network. It contains a lot of random batch files and self-executable programs I use for diagnostics and what not, and nearly every time I open the folder the computer hangs for 15-60 seconds. This happens on every machine, including the server (but not nearly as often as the clients). I've searched high and low and cannot figure it out and it's driving me crazy. Here are all the things I've tried to no avail: Disabled firewall (XP) and anti-virus (ESET NOD32) Deleted any desktop.ini file I can find in the share Disabled "automatically search for network folders and printers" Disabled "remember each folder's view settings" Set HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer NoRecentDocsNetHood = 1 Tried with mapped drives and with UNC shortcuts Ran CHKDSK Removed Read-Only attribute from all folders (well, tried to remove, it always came back on with a half check) Added the server's static IP to the hosts file on the clients I've tried monitoring the server's performance to see if anything makes sense. Occasionally the issue coincides with a spike in pages/sec (memory) but not always. Other than that, everything else seems normal. The anti-virus would seem to be the most likely cause to me considering the batch files and what not, but it still hangs when it is completely disabled. I'm at a loss and if anyone can help me with this I'd greatly appreciate it!

• Linux Startup Script after Gnome Login

  - by Eric

  I have a Fedora server that I want to spawn an interactive python script after the user logs on. This script will ask the user for various types of information for configuring the system or it will search for the previous config file and show them the predefined information. Originally I was going to put this in rc.local or make it run with init.d but that messed up the boot due to how the script is spawned. So I would like this script to run as soon as the user logs in to Gnome. I've searched around quite a bit and found this answer which appears to be exactly what I want, but it isn't working the way I want it to. Below is my entry. [Desktop Entry] Name=MyScript GenericName=Script for initial configuration Comment=I really want this to work Exec=/usr/local/bin/myscript.sh Terminal=true Type=Application X-GNOME-Autostart-enabled=true Whenever I login, nothing happens. So I then did a test to modified "myscript.sh" to just echo some text to a file and it worked fine. So it appears the portion that isn't working is the script popping open a terminal and waiting for the users input. Are there any additional options I need to add to make this work? I can confirm when I run /usr/local/bin/myscript.sh from the CLI it works fine. I have also tried adding "StartupNotify=true" and still no luck. Edit @John - I tried moving my Exec= to /usr/local/bin/myscript-test and this is what myscript-test contains. #!/bin/bash xterm -e /usr/local/bin/myscript.sh Yet again, when I just run the myscript-test it works fine. However when I put that in my autostart, nothing happens. Edit 2 - I did a few more tests and it did start working but I had to remove Terminal=True before the xterm would pop. Thanks for your help.

• Access server using IP on another interface

  - by Markos

  I am using Windows Server 2012 instead of a router for my home network. Currently I am using RRAS and computers from local network can access Internet correctly. Here is a map of the current setup: [PC1] ---| |---- (lan ip)[Server](wan ip)--> internet [PC2] ---| I have applications running on Server, such as IIS and others. All can be accessed from internet using wan ip and from lan using lan ip. I have a domain, lets say its my-domain.com, which is resolved to my wan ip. What I want is to enable my LAN computers to be able to connect to services on my server using the very same address as internet users: eg http://my-domain.com/. However this does not work for my lan computers. What I understand is that I need to set up some kind of loopback route in a way that packets comming to LAN interface get routed to WAN interface. But I haven't found how to achieve this (in fact, I don't know WHAT to search for). Feel free to ask for additional informations and I will try to update the question.

• IP tables blocking access to most hosts but some accesses being logged

  - by epo

  What am I getting wrong? A while back I locked down my web hosting service while hardening it or at least trying to. Apache listens on port 80 only and I set up iptables using the following: IPS="list of IPs" iptables --new-chain webtest # Accept all established connections iptables -A INPUT --protocol tcp --dport 80 --jump webtest iptables -A INPUT --match state --state ESTABLISHED,RELATED --jump ACCEPT iptables -A webtest --match state --state ESTABLISHED,RELATED --jump ACCEPT for ip in $IPS; do iptables -A webtest --match state --state NEW --source $ip --jump ACCEPT done iptables -A webtest --jump DROP However looking at my apache logs I notice various log entries in access_log, e.g. 221.192.199.35 - - [16/May/2010:13:04:31 +0100] "GET http://www.wantsfly.com/prx2.php?hash=926DE27C156B40E55E4CFC8F005053E2D81E6D688AF0 HTTP/1.0" 404 206 "-" "Mozilla/ 4.0 (compatible; MSIE 6.0; Windows NT 5.0)" 201.228.144.124 - - [16/May/2010:11:54:16 +0100] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 226 "-" "-" 207.46.195.224 - - [16/May/2010:04:06:48 +0100] "GET /robots.txt HTTP/1.1" 200 311 "-" "msnbot/2.0b (+http://search.msn.com/msnbot.htm)" How are these slipping through? I don't mind the indexing bots (though I am a little surprised to see them get through). I suppose they must be getting through using the ESTABLISHED,RELATED rules. And no, I can't for the life of me remember why the first match state rule is there So 2 questions: is there a better way to set up iptables to restrict access to specified hosts? How exactly are these 3 examples slipping through?

• nconf nagios config no services defined

  - by user1508056

  I've setup Nagios core on OSX 10.7 server via macports fine. It seems to load fine and the sample config files all copied over to /opt/local/etc/nagios/objects/ fine and are specified correctly in the nagios.cfg file. I then installed nconf manually and got it running without much fight. Then I clicked on "Generate Nagios config" in nconf and get 1 warning and 4 errors. When I expand the error box here what I see: Nagios Core 3.5.0 Copyright (c) 2009-2011 Nagios Core Development Team and Community Contributors Copyright (c) 1999-2009 Ethan Galstad Last Modified: 03-15-2013 License: GPL Website: http://www.nagios.org Reading configuration data...

Total Warnings: 1 Total Errors: 3 I've tried several different things (played with cache settings, changed file permissions/ownership, edited some config files manually, etc.) but nothing gets me past this step. The thing is, when I run 'sudo nagios -v /opt/local/etc/nagios/nagios.cfg' the output shows it is reading a number of services, a localhost, and a contact in the .cfg files...so I'm pretty confident those are ok and the problem is nconf isnt reading the correct .cfg files or something like that. Any ideas what to double check? I did lots of googling and found nothing on this specific issue--so either I'm special (I'm not) or am overlooking something really simple. The path to nagios binary is listed as /opt/local/bin/nagios, if that matters. Also, all the nagios files are owned by nagios:nagios, wheras nconf files are owned by user, with only the directories/files specified in the nconf docs belonging to the _www user and/or group (things like output, temp, config, etc.). Thanks.

• Windows XP Loading Problem

  - by Sadeq Dousti

  Sometimes, my Windows XP does not load correctly. It shows the login screen, and when I click my username, it load the desktop background, but the Explorer does not show up. So, I cannot see the icons on the desktop, the start menu, etc. If I press Ctrl+Alt+Del to show Task Manager, I can run programs (like media player or browser) from File--New Task (Run...). Also, in the Task Manager, I see Explorer.exe running. I tried to kill and re-run it, but nothing happens. I used Sysinternals Process Explorer to see if there were any odd process or odd behavior, but nothing was fishy. After several restarts, the system finally worked as expected. But this is not permanent: Sometimes, when I restart the system, it works just as described above (Explorer does not show up). But sometimes it works normally. I used Kaspersky to search for viruses, but nothing showed up. I think the info presented above is not enough to pinpoint the problem. Yet you might be able to tell me about a tool or something, which I can use to give you more info, or even solve the problem. PS: I can easily use the Safe Mode. It does not seem to suffer from this problem. Hence, I suspect there's some process (service) for which Explorer is waiting, but that process runs into trouble (say a race ondition, or an infinite loop) and so Explorer stalls as well.

• Multidimensional data table?

  - by ShreevatsaR

  [Apologies if this sort of question is off-topic for SuperUser. Please redirect to the right place if so.] There is a 3-dimensional array of values. (That is, instead of a table/2-dimensional array with values in a grid, the values can be thought of in a cube instead.) Is there a way to display this "cube" interactively, ideally on a webpage? Specifically, given the data, it would work something like this: the user selects two of the 3 variables. He then sees a "stack" of tables, one for each value of the third variable (cross-sections, in other words). By selecting the appropriate table from the stack, he can see the (i,j,k) value he wants. The "technology" for displaying such a thing (stacked tables, rotation, etc.) already exists, so this seems the sort of thing that someone ought to have written already. To be clear: I don't need sophisticated graphics necessarily, just the ability to select from cross-sections of variables. But I have no experience with (say, for displaying on a webpage) what web gadgets exist, so I'm clueless how to even search for one. (Google searches like "multidimensional data visualization" didn't throw up anything useful. Google Spreadsheets can do a few kinds of charts which can be embedded on a webpage, but I cannot tell if this is one of them.) [I can imagine how it ought to work for higher dimensions. For four-dimensions, instead of selecting just a stack, you'd first select an (i,j) from an "outer table", which would show all (k,l) values for that (i,j). For higher dimensions, inductively: you select (i,j), and then repeat what you'd do with 2 fewer dimensions.] So has this been written? Is this easy to write? Where ought one to look for such a thing?
