  • Best practice, or generally best way to set up web-hosting server, permissions, etc.

    - by Jagot
    Hi, I'm about to set up a server upon which a friend and I will be hosting web sites, and I'll be using Debian. I've set up a LAMP solution many times just to using for local testing purposes, but never for actual production use. I was wondering what are the best practices are in terms of setting the server up, in reference specifically to accessing the web root directory. A couple of the options I have seen: Set up a single user account on the server for us both to use and use a virtual host to point to the somewhere in the home directory, e.g. /home/webdev/www. Set each of us up a user account, and grant permissions in some way to /var/www (What would be the best way? Set up a new group?) I want to get this right when I first set this up as there won't be any going back for a while once our first site is up and running. Appreciate any guidance in advance.

  • X11 forwarding from one server to other

    - by n3oblit7
    I have a setup where I need to forward X11 from my local machine (laptop) to a Virtual machine. The server hosting this VM cannot be reached directly from my laptop. I need to first login to a gateway and from this gateway, I can access the VM. How can I forward X11 from my laptop to this VM? I have tried following but these do not work: [laptop # ] ssh -X [gateway] [gateway # ] ssh -X [VM] [laptop # ] ssh -tX [gateway] ssh -X [VM] I could forward X11 only till the gateway. (DISPLAY variable gets set on gateway)

  • HTTP Redirect from www.mydomain.com to my amazon ec2 account (instance)?

    - by fabius
    Hello! I have a domain, that is registered at a service provider but my site (wordpress blog) is hosted in a shared account with a friend in another other host service. I want to become seperate from this friend because I'm tired of boring him with my blog downtimes. Now, my problem is that I signed up to Amazon EC2 service and I created a instance (a virtual machine) to host my wordpress blog and now I'd like to redirect mydomain.com to this instance at Amazon EC2 and I don't know how to proceed in order to achieve that. The instance at Amazon EC2 is up and running (it's a 64bit linux machine) but I couldn't redirect mydomain.com to this instance at my host service webpanel. Could someone help me please???

  • Why am I getting 'undefined method' exceptions when executing 'run_list add', 'run_list remove' and 'rackspace server delete'?

    - by Peter Groves
    [Originally posted this to opscode forum, got no response] I’m testing out a free hosted chef-server account and multiple subcommands are failing with ‘Unexpected Errors’. Perhaps my version and the server version are incompatible? OS: Ubuntu 12.04LTS Local Chef: 10.12.0 (Installed through gem) Local Ruby: 1.8.7 Also, the workstation machine has been manually configured, but the client(s) I’ve been experimenting with are launched with the Rackspace plugin (using ‘knife rackspace server create…’) The problem commands seem to fail when talking to the host chef-server, however, before it ever tries to modify the client, so I don’t believe that’s where the problem exists. The virtual-servers that are launched by ‘knife rackspace server create’ are launched properly but then deleting them with knife fails. If I include a recipe in the run_list when I create the server, the recipe is properly added to the run_list. If I try to add it later or remove the one that there server was initialized with, those commands fail. Here is the output of a few relevant commands (with stacktraces): https://gist.github.com/7100ada3fd6690113697

  • Monitor a log file on Linux and send each line to another program

    - by mlambie
    I run an apt-cacher-ng server on Ubuntu Linux which writes logs in the following format: 1299745593|O|149406|XXX.XXX.XXX.XXX|uburep/pool/main/t/tiff/libtiff4_3.9.2-2ubuntu0.4_amd64.deb 1299745593|O|10154976|XXX.XXX.XXX.XXX|uburep/pool/main/l/linux-firmware/linux-firmware_1.34.4_all.deb 1299748529|O|39368|XXX.XXX.XXX.XXX|uburep/pool/main/n/nagios-nrpe/nagios-nrpe-server_2.12-4ubuntu1_amd64.deb 1300155440|O|680100|XXX.XXX.XXX.XXX|uburep/pool/main/t/tzdata/tzdata_2011c-0ubuntu0.10.04_all.deb It shows the timestamp, direction (in or out), byte count, IP and filename. Every time a line is written to it, I'd like to also send that line to another program. I will have this program insert the line into a database so that I can crunch some statistics about how much bandwidth we're saving through operating a caching server. I do not want to cat the log file every X minutes (via cron) looking for new entries as it'd be somewhat computationally uneconomical. Instead I'd prefer to have a daemon monitor the log, and when a change is detected, each line is sent to my database-insertion script. Will swatch achieve this, or are there better options?

  • Can't ping IPs for devices not part of Windows Domain

    - by GiddyUpHorsey
    I have a home network with a Trendnet wireless router and a Windows Domain. The DNS server is on a Windows 2000 Server and is configured to forward queries to DNS servers provided by the ISP. The router provides DHCP and is configured with the Windows 2000 Server as the DNS server. When I connect iPhones to the network over WiFi, the router can ping the iPhones through its browser based admin interface, but Windows machines that are part of the Windows Domain cannot. A laptop was connected to the network over WiFi that wasn't joined to the domain and it could see the iPhones. All machines either have a fixed or DHCP allocated IP on the 192.168.0.* subnet. How do I configure the DNS server or the Windows Domain so that Windows machines can see the iPhones?

  • How to set up Aptana Studio 3 with a Bitbucket private repo

    - by Titus
    I have just started playing around with Git and would like to push a personal project to a newly created, private repo on Bitbucket using Aptana Studio 3. I tried to use the Git integration in Aptana but I couldn't figure out where to enter my username and password for Bitbucket anywhere. I tried using the Team > Share Project context menu but that keeps throwing the following message: Warning: Permanently added the RSA host key for IP address '207.223.240.181' to the list of known hosts. Permission denied (publickey). fatal: The remote end hung up unexpectedly I'm pretty sure that's because my repo is private. However, I couldn't find a provision to provide any form of credentials for linking to a private repo. Any ideas?

  • What determines the time to first ping response in an OS?

    - by Stuart Woodward
    When a server (say Windows, Linux) is rebooted, it will take some time to respond to ping. I'm assuming that the software firewall has to be up before pings will be returned as there might be a setting to disable ping responses. Everyone knows that Windows and Linux have have totally different architectures so lets treat them separately. The answer I'm looking for is "After XXX is running, pings will be returned." It would be helpful to know where in the boot order this is too. i.e. at the start or end. I ask because we get questions from a customer about why it takes so long to respond to ping after creating a Virtual Machine. I'm sure this is just an artefact of the OS boot behaviour.

  • How to share my localhost over the internet?

    - by Loolooii
    I really want to share my localhost over the internet to show my friends the progress of the website we're working on, so that I don't need to upload it to the public server each time I make a change. showoff.io is not free and localtunnel gives me "failed to authenticate" when trying to upload my public key (a lot of people seem to have this problem and there doesn't seem to be a solution for this). Does anyone know any other free service I can use or any other solution at all? I'm using a Mac. Thanks. UPDATE: with localhost I mean a web server running on my computer, I have a dynamic IP address and no I'm not behind a router (just using a wireless modem).

  • Cannot SSH into Amazon EC2 instance

    - by edelwater
    I read: Cannot connect to ec2 instance http://stackoverflow.com/questions/5635640/cannot-ssh-into-amazon-ec2-instance Amazon EC2 instance ssh problems etc... But could not fix it: suddenly (after a year of service, no changes on my winscp settings) it gives me "network error connection timed out" (im using ec2-user) (also from the amazon console). Log FILE: http://pastebin.com/vNq6YQvN All Sites that run on it run fine port 22 is allowed (never changed it) (security group) using the correct ec2-user and domain via my winscp / putty i can connect to other hosting (via ssh) update: SOLVED. I spend 2 days without looking at my own IP address .... (since it did not change the past 3 years....). Your comments made the spark in my brain. thank you so much. (and only now i find dozens of discussions from angry users that the static addresses from my provider are changed to dynamic ones: http://gathering.tweakers.net/forum/list_messages/1501005/12 ...)

  • Serve my website from different server during downtime

    - by nfedyashev.mp
    I have a VPS server running in the cloud. Fully automated server image upgrade/downgrade(by RAM/HDD plans). The problem is that server upgrade/downgrade takes time and involves total unavailability during this period(up to 30 minutes). Goal: during this downtime server my website(http://mydomain.here) from different server with some message like "Under construction". How can I do this? -- mydomain.here is hosted on godaddy and uses its DNS(If I call it right). It's pointing with A-record to my VPS's IP address now. Change in these DNS settings will take more than 30minutes, so it's not an option. How can I find mode "dynamic" DNS? What should I learn?

  • VPN is working, except for DNS lookups. Firewall (Cisco ASA 5505) issue?

    - by macke
    I've got the following set up: LAN -> DHCP / DNS / VPN server (OSX 10.6) -> Cisco ASA 5505 -> WAN Connecting to the LAN via VPN works fine. I get all the details properly and I can ping any host on the internal network using their IP. However, I can't do any host lookups whatsoever. I've looked through the logs on and found this nugget in the firewall log: 3 Sep 08 2010 10:46:40 305006 10.0.0.197 65371 portmap translation creation failed for udp src inside:myhostname.local/53 dst inside:10.0.0.197/65371 Port 53 is dns services, no? Because of that log entry, I'm thinking that the issue is with the firewall, not the server. Any ideas? Please keep in mind that I have very little knowledge and experience with this kind of firewall and the little experience I do have is with the ASDM GUI console, not the CLI console.

  • setting up ssh on minix 3.2

    - by Mark
    I have install MINIX 3.20 on VMware player on LINUX. Now, I am trying to ssh into Minix from the same Linux machine, but I am encountering some problems. First I installed openssh on MINIx then I tried to ssh onto the Minix virtual machine with ssh [email protected] but I got the following output: [email protected]'s password: Permission denied, please try again. [email protected]'s password: Permission denied, please try again. [email protected]'s password: Permission denied (publickey,password,keyboard-interactive). I am sure the password I entered is correct, I have tried to ssh into MINIX on MINIX and it worked but not when I tried it from my linux machine. I have followed the steps for setting up ssh from this webpage, but it didn't work as shown above.

  • How to have a soft-real-time process in presense of heavily swapping IO-intensive background load?

    - by Vi
    schedtool: PID 32301: PRIO 4, POLICY R: SCHED_RR , NICE -20, AFFINITY 0xf ionice: realtime: prio 4 But the music is stumbling anyway. Background load is low prio (SCHED_IDLEPRIO, idle ionice), but uses a lot of memory (more than is physically available) and does a lot of IO and calculations. Latencytop shows about 1500ms for: Following symlink Writing buffer to disk (sync) Page fault Writing a page to disk both for the bg load and for unrelated processes. Load average is 10 and counting. Why cannot it allocate, for example, 200MHZ of one of the cores and 32M of memory and not less than once per second opportunity for IO for mplayer to make it happy while continuing calculations on the background? Or: why it cannot leave background task and swap loving each other but keeping the rest of the system as if there were no background load? How to have RT processes AND heavy bg load simultaneously (without of virtual machines)?

  • Dynamic Subdomains

    - by crash
    On my new site I want to have dynamic subdomains. I'm trying to make it so that the subdomains use the same web root as the main domain, all under a single CodeIgniter installation. For example, subdomain.example.com would lead to example.com/subdomain, which is actually example.com/index.php/subdomain. I've already the DNS, virtual hosts set up but I"m getting caught up on the .htaccess. The effect of the linked htaccess is that when navigating to any subdomain, it gets caught up in an infinite loop. (Error log after one request.) It's the same effect for www., which should just resolve to the main domain.

  • Can a named (bind) crash make a server unreachable?

    - by giorgio79
    My server recently became unreachable, and after restart a named error was the last line I found in /var/log/messages before restart: Jun 26 00:15:06 host named[1303]: error (network unreachable) resolving 'dlv.isc.org/DNSKEY/IN': 2001:500:71::29#53 Jun 26 06:38:55 host kernel: imklog 5.8.10, log source = /proc/kmsg started.

I doubt it, as I assume I should still be able to login with ssh via IP, but the server did not respond...So, I am trying to make heavy guesses here.

  • How to make a server check it's own availability on the web?

    - by Javawag
    Hi all, Just a quick question – my server is running at my house serving www pages at www.javawag.com. The problem is that my home internet connection keeps dropping randomly - for about 10 mins at a time. This is only an intermittent problem and will go away soon I hope. However, my server doesn't recover properly - when the connection comes back, I can still access it at 192.168.0.8 (locally) without any issue, but at www.javawag.com there's no reply! (Just an aside - my home internet connection is dynamic ISP, the domain www.javawag.com points to javawag.dyndns.org which in turn points to my IP, updated every minute by ddclient on the server) Is there some way for the server to check if it's accessible from the outside world periodically, and if not restart Apache/reboot? Oh, and if I reboot the problem fixes itself also! Javawag

  • Server suddenly running out of entropy

    - by Creshal
    Since a reboot yesterday, one of our virtual servers (Debian Lenny, virtualized with Xen) is constantly running out of entropy, leading to timeouts etc. when trying to connect over SSH / TLS-enabled protocols. Is there any way to check which process(es) is(/are) eating up all the entropy? Edit: What I tried: Adding additional entropy sources: time_entropyd, rng-tools feeding urandom back into random, pseudorandom file accesses – netted about 1 MiB additional entropy per second, problems still persisted Checking for unusual activity via lsof, netstat and tcpdump – nothing. No noticeable load or anything Stopping daemons, restarting permanent sessions, rebooting the entire VM – no change in behaviour What in the end worked: Waiting. Since about yesterday noon, there are no connection problems anymore. Entropy is still somewhat low (128 Bytes peak), but TLS/SSH sessions have no noticeable delay anymore. I'm slowly switching our clients back to TLS (all five of them!), but I don't expect any change in behavior now.

  • Squid proxy server not forwarding traffic

    - by DilbertDave
    I'm trying to set up a web filtering system (dans guardian) on my home network but am failing at the first hurdle - configuring the Squid Proxy server. No matter what I do I cannot seem to configure it properly and I just receive the 'Requested URL could not be received' error page. If I remove the proxy setting on the browser everything works normally. Ultimately I want to run this on something like a Raspberry Pi but at the moment I'm testing with a virtual machine (although efforts with a netbook were equally unsuccessful). The VM has a clean installation of Linux Mint 15 and I've installed squid via apt-get. I've followed numerous walkthroughs but this on (https://help.ubuntu.com/lts/serverguide/squid.html) pretty much sums up the process I've been taking. I'm obviously missing something but cannot figure it out - any assistance appreciated.

  • restrict windows remote desktop

    - by radioactive21
    Is there any way to prevent users from launching and using remote desktop and to restrict it to only local admins or domain admins? The reason being is that we do not want users to remote desktop home, but at the same time we want it to be available to certain users like administrators or power users. Ideally there is a group policy that can be set to groups or users who have access to the remote desktop application from their machine. Clarifications: I need the machine to be able to still have remote desktop work, just only with a specific user or group. The point is that we allow certain users to use remote desktop and others to not have access to it. There are machines where there are multiple users, so we cant just block a whole machine or by IP. This needs to be done per a user account or login.

  • Keepalived with apache unable to bind interface on Backup server

    - by davideagle
    I have two debian 6 servers running keepalived 1.1.20 with one server acting as a Master and the other as a Backup. Both servers host apache 2.4 that have a global Listener on all interfaces on port 80 (Listen *:80) how ever I have some sites that require a listener for port 443 (SSL) and that is configured for each VirtualHost in the Apache config since I do not want every VirtualHost to listen on port 443. The problem is when I try to start Apache on the Backup machine that does not hold the virtual interface the VirtualHost is supposed to be listening on, I get AH00072: make_sock: could not bind to address 1.1.1.1:443. I know this is expected behavior of Apache. The real question is are there any known workarounds or solutions to this scenario?

  • Access Denied on LAN IIS Access via Integrated Authentication

    - by Pharao2k
    I have an IIS 7.5 (Win2k8R2) Webserver, which publishes an UNC Share (on a Fileserver) with restricted access. The AppPool Identity is a Domain User-Account with read access to mentioned UNC path. Authentication modes are set to Anonymous and Integration Authentication. When I access the path via localhost from the Webserver itself, it works, but if I try the Hostname or IP from either the Webserver or a Client, I get three authentication prompts (does not accept my credentials) and a 401.3 Unauthorized error message (but it states that I am logged in as my normal credentials which definitely have access rights to the UNC path and its files). Security Zone is set to Local Intranet. Sysiniternals Process Monitor lists CreateFile operations on the UNC path (and other existing files in it) with Access Denied and Impersonating on the correct credentials. I don't understand why it is not working, it seems to use the correct credentials on every step on the way but fails with is operations.

  • How to configure HA iSCSI for Solaris 10

    - by Noah
    BACKGROUND: We have a StarWind NAS that we are currently using for High Availability storage with our Windows network. Starwind has mirrored drives and multiple ip paths, that the Windows Server combines into one HA disk store. QUESTION: How do I accomplish the same thing under Solaris 10? I've looked at ZFS but to document seems to indicate that ZFS wants to do its own raid/mirroring. I can also attach via iSCSI from Solaris and am presented with both drives being served by the Starwind NS. So, how do I configure solaris so that disk M1 and M2 are considered as a single fault tolerant drive?
