• Problem after system update. Root permission denied, user lib permission denied.

  - by gregor

  As I updated opensuse 11.1 with update packages from october and november 2009, I couldnt use the command ping. For root it gives Permission denied and for a regular user I get libresolv.so.2: cannot open shared object file: Permission denied. The other coulprit besides the update could be the instalation of google-chrome (.deb file to .rpm, some symbolic links for libs to make chrome work). When the system rebooted, X server also became blank. Before the reboot it worked, as did chrome, but the ping command didnt work even before the reboot. Any ideas? I ran some sort of disk check from a rescue CD, libresolv seems as other libs, root has uid=0 ...

• MOSS 2007 links issue

  - by r0ca

  I have a user that for some reason lost her "My Site" & "My Links" link on her local computer. When she logs into a Citrix server she can see them. I have had her dump temp Internet files and put the site in her trusted sites but nothing is working. I think thins started after some Windows updates but not sure. Any ideas on this one? BTW, it's not turned off kin Central Admin and none of her group memberships have changed.

• Changing Network Path of Offline Files

  - by Adam

  Many of our users have their Home folder set as Available Offline. Their Windows 7 laptops will not be back on our network for a few weeks. In the mean time, we're setting up new servers and reorganizing our files, so the network path to the Home folder is going to be completely different. Based on some testing I did, when the users return, any files they've created or modified while offline will be gone, and the new Home folder will be there and not set to sync. The offline cache of the old Home folder is still accessible through the Sync Center, but they're not going to want to dig through that and try to find what's missing. Avoiding this would involve keeping the old server around and moving everyone to the new location in person, so we know for sure they're synced first. Is there any way to avoid this that isn't as tedious, like a quick registry edit or something that will point the old offline cache to the new location?

• Hanging page loads every n loads

  - by Christian

  Hi Guys I recently moved my site to a new server (Apache 2, PHP5, MySQL5). The site is an Invision based forum. Every few posts / topics it just hangs. The data has been written because if you stop and reload, the post / thread is there. I thought it was a write issue initially, but nope. So, the data is written but the page load never completes. It doesn't leave the page where the data has been input. Whats the best way to trouble shoot this issue? The only thing I have done recently is reduce my MySQL timeouts, but I can't see that being an issue as the values are still big enough and there are no mentions of timeouts in the MySQL log. (For the record there is nothing in PHP's error log either) Thanks in advance!

• All nework interfaces hang for seconds while one interface goes up/down

  - by user3698377

  I am building a client/server application that uses several network interfaces in parallel for redundancy, and I have noticed that while one network interface goes down or goes up, the communication on other interfaces hangs for several seconds. I could reproduce this behavior without my application in a simple way: there are 2 interfaces available on computer 1 ( Ethernet and WiFi ) ping from computer 2 the IP address of the Ethernet connection of computer 1 disconnect the WiFi of computer 1 ping hangs for seconds, and then the packets are traveling again between the 2 computers. The hanging happens as well if I turn back on the WiFi connection on computer 1. It happens as well if I ping the WiFi IP, and turn off/on the Ethernet connection ( or unplug/plug the cable). I am using Linux Ubuntu 12.04 on both computers. Any ideas why is this happening, and if / how can it be avoided?

• Could not Upload file in network mapped drive using asp.net/vb.net

  - by Hasan

  I have tried several times to upload file remotely to a mapped network drive, but it is raising an exception: Could not find a part of the path 'X:\test\testing.wav'. I read through various internet /blog/ Microsoft help sites, but I still don't know what is wrong. Does anyone know what is causing this problem and how I can correct it? It works fine when I am uploading to a local drive as a test. It is also working When I am running the code from the development server, but if I try with published code, then it fails. :(

• How to restrict user to a particular folder in CentOS 6?

  - by Chris Demetriad

  I will need to create users so developers can log in and clone/pull/push changes/repositories from a github like platform. I've managed to add a user (using the root) to this CentOS machine; I now have this line in /etc/passwd: chris:x:32008:32010::/home/chris/public_html:/bin/bash ..and this in /etc/shadow: chris:$1$ruUeLtTu$onAY2hdu1J.UmHajEIlmR.:15385:0:99999:7::: I am able to SSH the server, I have permission to create a folder and I guess that should be enough. But I am able to see other files and folders outside public_html. How can I actually restrict the user to a particular directory so he can't "cd out" of his folder? Update: root@echo [~]# ls -ld /home/moove drwx--x--x 21 moove moove 4096 Mar 22 16:16 /home/moove/ root@echo [~]# ls -ld /home/moove/public_html drwxr-x--- 11 moove nobody 4096 Mar 27 11:29 /home/moove/public_html/ root@echo [~]# ls -ld /home/moove/public_html/dev drwxr-x--- 12 moove nobody 4096 Mar 27 14:47 /home/moove/public_html/dev/ root@echo [~]# ls -ld /home/moove/public_html/dev/arsenal drwxr-xr-x 3 arsenal moove 4096 Mar 27 14:53 /home/moove/public_html/dev/arsenal/

• Anyone else being hit by traffic on TCP port 11370

  - by Jakub

  I've been watching my logs (Ubuntu 9.10 server) and dunno about any of you but I am getting a ton of traffic from sources like Russia, Romania, etc.. on port 11370 (my iptables are logndrop'ing it. But was just curious). Some googling revealed this info: http://www.keysigning.org/sks/ -which seems to use port 11370 & 11371 Could that be the service they are scanning for (i don't run it)? ICS shows this: https://isc.incidents.org/port.html?port=11370 Just curious what you guys think and if anyone has seen this before? If need be I can post my log on here, but its just a dropped log of TCP port 11370 from various IPs. Thought it was strange as thats the ONLY Port I seem to repeatedly be hit on (from logs). I'm running on a Linode (VPS) if that matters to annyone.

• Multiple PHP versions running as cgi

  - by Pierre

  I'm trying to install a second version of PHP, to run alongside the current version of php. I've compiled the latest php source from github (5.5-DEV), and I'm trying to run it as CGI. Here is my virtual host config: <VirtualHost *:8055> DocumentRoot /Library/WebServer/Documents/ ScriptAlias /cgi-bin/ /usr/local/php55/cgi Action php55-cgi /cgi-bin/php-cgi AddHandler php55-cgi .php <Directory /Library/WebServer/Documents/> Options Indexes FollowSymLinks Includes ExecCGI AllowOverride All Order Allow,Deny Allow from all </Directory> DirectoryIndex index.html index.php </VirtualHost> But when I go to http://127.0.0.1:8055/info.php, I get the following error: Forbidden You don't have permission to access /cgi-bin/php-cgi/info.php on this server Edit I'm now switching between LoadModule php5_module /usr/local/php54/libphp5.so and LoadModule php5_module /usr/local/php55/libphp5.so It works for now, but is not ideal. I would like to have the different versions of php on different virtual hosts

• Testing Tomcat with Virtual Hosts

  - by Marty Pitt

  I'm trying to test Tomcat virtual hosts on my dev machine (windows 7/Tomcat 6). I'd like to have requests for localhost, test1.localhost and test2.localhost all route through to the same tomcat instance. I've edited my hosts file to look as follows: 127.0.0.1 localhost ::1 localhost 127.0.0.1 test1.localhost 127.0.0.1 test2.localhost And added modified the Engine in server.xml as follows: <Engine defaultHost="localhost" name="Catalina"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase" /> <Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true" xmlNamespaceAware="false" xmlValidation="false"> <Alias>test1.localhost</Alias> <Alias>test2.localhost</Alias> </Host> </Engine> However, I'm getting a 404 when hitting test1.localhost:8080/myWebApp, although localhost:8080/myWebApp works fine. I can ping test1.localhost fine. What have I missed?

• Monitoring Maximum Process Network Activity

  - by user125973

  We have a collocated server on which we run some OpenVZ hosts. Recently, we have had to pay a lot extra we keep exceeding our bandwidth quota. Our quota is 5 Mb/s but we have spike to almost 50. I looked at the graphs and there are some spikes happening at some intervals. I want to know which process is causing this so I need a tool that monitors the processes and gives me the one with the maximum instant traffic (It doesn't matter how much traffic we have as long as we don't exceed the 5Mb/s quota). Does anyone have a recommendation for this? My hosts are CentOS 5 with OpenVZ so I can see all the containter processes from the host, if that helps in any way.

• ubuntu: sending mail with postfix?

  - by ajsie

  i've got some questions about how it works: so ubuntu server comes with postfix installed. if i want my php script to send a mail to lets say [email protected], how does it work? do i have to specify any ip to another MTA (my ISP's MTA?) in postfix's configuration file? and if someone sends back, will it get to my ip? is it postfix that receives it? or has it to do with fetchmail?

• Postfix dynamic smtp_helo_name

  - by William

  I have a mail server that relays e-mails for two different domains. I want the smtp_helo_name to be different based on the domain. I'm assuming there is no way to do this via checking the mail headers, so I was wondering if there was a way to do it by sending mail for one domain to one IP, and mail for the other to another. I tried modified master.cf to do this: localhost:smtp inet n - n - - smtpd ip1:smtp inet n - n - - smtpd ip2:smtp inet n - n - - smtpd -o myhostnamee=example2.com And setting smtp_helo_name to $myhostname in main.cf I also tried doing -o smtp_helo_name instead, neither work. Any suggestions would be great. Thanks

• Remove apache from ubuntu

  - by Keyo

  I want to remove apache as if it was never installed, no config files left behind. I intend to reinstall apache2 fresh. I have tried various combinations of apt-get options to no success. apt-get remove apache2 apt-get remove --purge apache2 apt-get purge apache2 apt-get autoremove apache2 None of these totally remove apache properly. Nothing works, the /etc/apache2 directory still exists. So I deleted it. When I install apache the folder is never created. Running Ubuntu server 10.10.

• serving static assets via http is really slow compared to sshfs (apache2/nginx)

  - by s1lv3r

  After migrating to a new VPS I had some users complaining about slow loading images on their sites. After creating some test files with dd I realized that I can download all files via sshfs with full speed while downloads via web are painfully slow. The larger the file is and the longer the transfer takes, the slower the transfer speed gets. I thought I had some problems with Apache and just spend the whole evening with replacing Apache2 against nginx for static file serving - with no effect at all. No I/O wait states in top. Tons of RAM free, no high CPU utilization and hdparm shows a decent I/O performance at all times. I just have no idea anymore, what's happening on this server. This is a link to a demo file: http://master.dealux.de/file.tgz Anybody an idea what I can check out?

• CentOS, YUM Errors?

  - by mike

  Hi, I am using a Media Temple DV server with CentOS upon trying to install ImageMagick via yum, I get the following error: There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: /usr/lib/python2.4/site-packages/rpm/_rpmmodule.so: undefined symbol: rpmdbCheckTerminate Please install a package which provides this module, or verify that the module is installed correctly. It's possible that the above module doesn't match the current version of Python, which is: 2.4.3 (#1, May 24 2008, 13:47:28) [GCC 4.1.2 20070626 (Red Hat 4.1.2-14)] Can anyone shed some light on what I might be able to do to fix this? Thanks!

• How to configure Apache on Amazon Elastic Beanstalk

  - by Ian

  My PHP5.3 application is currently running on a Windows 2003 server running XAMPP 1.7.7 I've decided it will be better if I can get it moved onto the cloud, and Amazon Elastic Beanstalk looks like the easiest way to go. I'm starting with a 64bit Amazon Linux running PHP 5.3 container. My next step is to limit access to the website with an htpasswd file. I'd rather not use .htaccess files. How do I configure Beanstalk Apache conf file settings (on Windows the settings are stored in httpd.conf)?

• LDAP Authentication for multiple AD Domains

  - by TrevJen

  I have 3 full trust domains (2 child and one root). I need to use LDAP to allow authntication for domain users. The trick is that I need the application to use an AD server for the child domain BUT proxy the LDAP query and authentication for the root domain. I see that it maty be possible with AD LDS and some trusts and synching, but it looks pretty hairy and overly complicated. The short of it is: 3 domains (Parent, ChildA, ChildB) My 3rd party app will need to use ChildA domain servers to authenticate either: a. a user in the parent domain or b. a user in the ChildB domain I already have full trusts between all domains, and regular NTLM authentication works fine (unless you are trying to authenticate with LDAP)

• Are there any negative impact running all services on a single static IP?

  - by Jake

  I need to setup a VPN trunk (with remote branch office location), Video Conference and Web Server on-premise in the office. I am used to ISP providing blocks of 8 or 16 IPs. But I have a new ISP which says they only can provide a single IP. Are there any issues with running all services on a single IP? I don't think this has any thing to do with bandwidth..? I'm not using SSL certificates... I can do port forwarding to different machines... What else...? Disclaimer: I am a programmer by training. Sorry for noob question.

• Choosing a low cost wildcard SSL cert (PsotiveSSL, RapidSSL, or other)?

  - by Malcolm

  I'm looking to put in place a wildcard SSL certificate for a server that will be providing REST style web services to multiple subdomains. We use NameCheap.com for our DNS services and they offer a choice of 2 very competitively priced wildcard certs: PositiveSSL Wildcard $129.99/yr RapidSSL Wildcard $148.88/yr Is there any reason to choose one of these branded certs over the other? Or are there problems with these low cost certs that we should aware of? If so, what SSL vendor/products do you recommend and why do you recommend them? Thank you, Malcolm

• Freebsd or Linux? as BGP router over 100mbps

  - by Yucong Sun

  I am building a server to act as a BGP border router for my 100mbps uplink in ISP. I needs these feature: 1) Dual stack BGP peering/routing (at least 100Mbps, maybe more). 2) Potential full internet BGP feed. 3) Some basic ACL functionality. The hardware is L3426/8G ram. NIC will be on-board dual port Broadcom 5716. I've worked with Linux extensively before and it seems to be able to handle 100mbps, but I heard FreeBSD is faster on networking stuff. Which one should I use? And do we have some performance benchmark numbers out there? Cheers.
