  • Small office network setups

    - by user39822
    I work at a small office and we're overhauling our network setup there. We're a web dev company and at the moment we have 50+ production sites running on the same machine that runs our internal email, which is just plain stupid. We're moving all our client hosting off site and are now looking for something to run our internal office requirement. Below is a brain dump: Equal amount of Mac & PC, about 25 machines in total. We need a central "server" to host files that should be accessible everyone as a "network drive". If possible we'd like to use low cost hardware for this (Mac or Win based). Disk space should be upward of 1TB. Ideally we should also be able to run a small web server on this machine (LAMP stack) to run some planning and billing applications we wrote ourselves. We need some sort of MS Exchange alternative for things like a shared calendar and especially being able to set Out of Office replies. We have one printer that is connected to the network Setup should be something can preferably be managed easily via a graphical interface and NOT require command line skills. Users want to keep using Apple Mail or MS Outlook After a quick google I came across the Zimbra collaboration suite, can anyone recommend this or any other solution for our office?

  • Backup solution to backup terabytes and lots of static files on linux server?

    - by user28679
    Which backup tool or solution would you use to backup terabytes and lots of files on a production linux server ? Note that the files are all different and almost never modified, and usage is mostly adding files, so data volume is today 3TB growing all the time at around +15GB/day. Please do not reply rsync. Basic unix tools are not enough, rsync does not keep history, rdiff-backup miserably fails from time to time and screw the history. Moreover these are all file based backup, which put a lot of IOwait just to browse directories and query stat(). But i guess, except R1Soft CDP, there is no way around that. We tried R1Soft CDP backup, which is block level backup, and it proved good and efficient for all our other servers, but systematically fails on the server with 3 terabytes and gazillions of files. That is already more than 2 months that the engineers of R1Soft and datacenter are playing a hot ball game... and still no backup except regular rsync We never tried big commercial solutions, except R1Soft CDP since it was provided as an optional service by the datacented hosting our servers.

  • Why would e-mail from our own domain not be forwarded to gmail

    - by netboffin
    To solve a problem with spam on our server we tried to forward e-mail from our dedicated server's mailserver(matrix smtp service) to gmail, but while most e-mails got through e-mail from our own domain all went missing. They weren't in the inbox or spam or anywhere else. We've had to go back to using the old system, which means my boss gets a huge amount of spam. We have a windows 2003 server with iis 6 and the matrix smtp service installed. I've toyed with the idea of installing a mail proxy like ASSP but it looks pretty complicated. We're hosting 20 domains on the server as well as our own which has an online shop whose payment system depends on email. I can't start playing around with complicated solutions when it could have disastrous consequences and I don't know enough to implement them safely. So my question has two parts: Part One: Why can't we forward e-mails from people using the same domain. If our domain was foobar.com then [email protected] can't receive from [email protected], but he can receive from everyone else. Part Two: Is there a really simple server side solution to spam that would work with matrix? For instance popfile?

  • VirtualBox: using physical partition as virtual drive

    - by Hamman Samuel
    Background: I am using VirtualBox installed on Windows 7. From within VirtualBox I am using Xubuntu as a virtual OS. The reason I chose this approach is so that I don't have to keep turning off Windows and rebooting from Xubuntu every time I needed to switch OSes. And VirtualBox's seamless mode is pretty amazing to allow me see Xubuntu and Windows 7 all in one screen. Issue: Now I am thinking of a way to have Xubuntu more integrated into my system. By this I mean I want to have a physical partition for Xubuntu. But I want to still have the feeling of the seamless mode. Question: So finally, my question is: is it possible to load a partition in VirtualBox as a virtual OS? Case examples: Ideal scenario would be: I physically boot up and login to Windows 7. Now I want to access Xubuntu, so I load VirtualBox and access my Xubuntu partition without rebooting. And the other way around too, i.e. I boot up the system, login to Xubuntu, and can access the actual Windows 7 partition through VirtualBox. Other info: Please note that I am not talking about getting access to files, as I have a completely separate partition for my files, and am very familiar with VirtualBox's Shared Folders option.

  • CentOS 5 VPN Server won't work

    - by Miro Markarian
    I have a CentOS 5 server configured to be both a L2TP server and a PPTP server + a radius server for hosting the AAA. My problem is that, the L2TP works great and I can connect to it, but can't connect to PPTP and every-time it ends up with error #619 when it gets to the verifying username and password section. Here is the log I got from /var/log/messages Dec 17 07:40:02 serverdl pptpd[8570]: CTRL: Client 5.52.247.62 control connection started Dec 17 07:40:03 serverdl pptpd[8570]: CTRL: Starting call (launching pppd, opening GRE) Dec 17 07:40:03 serverdl pppd[8571]: Plugin radius.so loaded.

I believe it must be a radiusclient issue because both of the PPTP and L2TP services use radius to authenticate. And another thing I think must be the issue is that when assigning IPs to the PPP interfaces, I have done the following config. Is that right? For L2TP: localip 10.10.10.1 remoteip 10.10.10.2-254 For PPTP: localip 10.10.9.1 remoteip 10.10.9.2-254

  • How to set up daisy-chained routers for separate sub-nets?

    - by joe
    This question seems to be similar to others, but I'll take a shot anyway. A client recently switched ISPs from TDS to Comcast Business Class. Before the switch, they had 5 static IP addresses assigned. Now they'll have a single IP address that will change whenever Comcast decides to do so. The issue is that this internet connection will be shared among two companies, both having (and wanting to keep) their own private subnets. Because TDS was supplying multiple IP addresses to the one location, this allowed me to put each router on the switch. Now, with Comcast, they only get one IP address, meaning there has to be a main router before the subnet routers. Luckily, the cable modem has a built-in router, which I would like to connect to each company's router, and still have DHCP enabled on all accounts. Question: What do I need to do to the subnet routers to keep them separate from each other, but still allow internet access from the main router. I would love to say "I tried this", and give you links, but everything I find on the internet only mentions daisy-chaining routers with DCHP disabled.

  • Internet Explorer / Windows 7 does not want to show HTML file from local network drive

    - by Jaanus
    Setup: I have Windows 7 running inside VirtualBox on Mac OS X host. I have a shared drive with some HTML files, that I am mounting as a local drive W: in Windows, from the VirtualBox server \VBOXSVR. I want to look at them with a browser in Windows. Chrome in Windows 7 opens and shows those HTML files just fine (file:///W:/welcome.html). But Internet Explorer does not, and shows this error instead of the files: Internet Explorer cannot display the web page What you can try: [button Diagnose Connection Problems] More information This problem can be caused by a variety of issues, including: Internet connectivity has been lost. The website is temporarily unavailable. The Domain Name Server (DNS) is not reachable. The Domain Name Server (DNS) does not have a listing for the website's domain. If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section. For the internet zone in the status bar, it shows: Internet | Protected Mode: On IE settings are a mystery to me, and I could possibly get it to work by tweaking IE settings, but I don't know which ones. How do I make IE show the same files that Chrome is happy to show? (Chrome showing them means that the files themselves are fine, there is something about the setup that just makes IE be a diva.)

  • Mapped network drive connection timeout

    - by Terix
    I have server "Alpha" and server "Beta". Server Beta has a shared folder, that is mapped on server Alpha as "X:" On server Alpha there is a .vbs script that runs and take some files on local drive and copy them on X: drive. My issue is if no user log on server Alpha for a long time, it seems like the tcp connection underneath the mapped drive has a timeout, and the vbs script fails on the copy of file. As soon I log with remote desktop on Alpha server, the .vbs is successfull on the copy of the files. I have made many tests, using file logs to check what was happening and I found no way to refresh the connection and let the .vbs be able to copy files unattended.. I have always to log with remote desktop on Alpha server to refresh the connection and let the .vbs copy the files without issues. What can I do to avoid to log every time? The .vbs script runs 3 times a day and is very annoying. I do not have control over server Beta so I cannot change anything there, and I am very limited on changes I can do on server Alpha ( I cannot change registry and that sort of things)

  • Would like to change audio codec, but keep video settings with ffmpeg

    - by Craig Tataryn
    I have a video for which I'd like to convert the audio codec to AAC 320 kbps / 44.100 kHz. What would I use for ffmpeg switches such that all the video settings and codec remain the same, but only the audio codec and settings change? Here's my video: $ ffmpeg -i Winnipeg.rb\ Scala-Talk.mov FFmpeg version SVN-r25375, Copyright (c) 2000-2010 the FFmpeg developers built on Oct 6 2010 13:02:41 with gcc 4.2.1 (Apple Inc. build 5664) configuration: --enable-libmp3lame --enable-shared --disable-mmx --arch=x86_64 libavutil 50.32. 2 / 50.32. 2 libavcore 0. 9. 1 / 0. 9. 1 libavcodec 52.92. 0 / 52.92. 0 libavformat 52.80. 0 / 52.80. 0 libavdevice 52. 2. 2 / 52. 2. 2 libavfilter 1.48. 0 / 1.48. 0 libswscale 0.12. 0 / 0.12. 0 Seems stream 0 codec frame rate differs from container frame rate: 2000.00 (2000/1) -> 10.00 (10/1) Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Winnipeg.rb Scala-Talk.mov': Metadata: major_brand : qt minor_version : 537199360 compatible_brands: qt Duration: 01:10:53.00, start: 0.000000, bitrate: 283 kb/s Stream #0.0(eng): Video: h264, yuv420p, 800x598, 94 kb/s, 10 fps, 10 tbr, 1k tbn, 2k tbc Stream #0.1(eng): Audio: adpcm_ima_qt, 22050 Hz, 1 channels, s16 Stream #0.2(eng): Audio: adpcm_ima_qt, 22050 Hz, 1 channels, s16 At least one output file must be specified Many thanks in advance!

  • Creating multiple SFTP users for one account

    - by Tom Marthenal
    I'm in the process of migrating an aging shared-hosting system to more modern technologies. Right now, plain old insecure FTP is the only way for customers to access their files. I plan on replacing this with SFTP, but I need a way to create multiple SFTP users that correspond to one UNIX account. A customer has one account on the machine (e.g. customer) with a home directory like /home/customer/. Our clients are used to being able to create an arbitrary number of FTP accounts for their domains (to give out to different people). We need the same capability with SFTP. My first thought is to use SSH keys and just add each new "user" to authorized_keys, but this is confusing for our customers, many of whom are not technically-inclined and would prefer to stick with passwords. SSH is not an issue, only SFTP is available. How can we create multiple SFTP accounts (customer, customer_developer1, customer_developer2, etc.) that all function as equivalents and don't interfere with file permissions (ideally, all files should retain customer as their owner)? My initial thought was some kind of PAM module, but I don't have a clear idea of how to accomplish this within our constraints. We are open to using an alternative SSH daemon if OpenSSH isn't suitable for our situation; again, it needs to support only SFTP and not SSH. Currently our SSH configuration has this appended to it in order to jail the users in their own directories: # all customers have group 'customer' Match group customer ChrootDirectory /home/%u # jail in home directories AllowTcpForwarding no X11Forwarding no ForceCommand internal-sftp # force SFTP PasswordAuthentication yes # for non-customer accounts we use keys instead Our servers are running Ubuntu 12.04 LTS.

  • Synchronising a remote folder with a local one.

    - by Workshop Alex
    I am using a network disk (that's connected to my router by USB) to store several data files. A simple .NET application that I've created is supposed to read and modify these data files. However, some security issues are preventing this application to access these files directly. (Actually, these have been built-in to my application on purpose since it's not going to support NAS disks.) Since this disk is shared with several computers, I just want to have a simple synchronisation method, which will copy the files to a local folder where3 my application can access them. And, once modified, it should send back the modified files to the NAS disk again. I have two options: 1) Build a second application to do my own synchronisation. 2) Find some build-in function inside Windows 7 Ultimate which can do this for me. Option 2 is preferred. Option 1 is something I can do easily, if need be. I don't need third-party tools. (Still, feel free to add some references to good tools, although I won't accept them as answers.) Basically, is this possible with Windows 7 and if so, how?

  • Setting up virtualbox for outside access

    - by Morgan Green
    I have a computer running a server that my subdomain on my shared hosting account points to. IE subdomain.mydomain.org goes to my home server. Now then; what I'm wanting to do is be able to access my VirtualBox servers through that subdomain and a different port. E.G Ubuntu Virtual Box Server 1 Username:Ubuntuhost1 Password:MyUbuntuHost1 Port:4000 Internal IP: 192.168.1.60 External IP: 24.29.138.45 Ubuntu Virtual Box Server 2 Username:UbuntuHost2 Password:MyUbuntuHost2 Port:4001 Internal IP: 192.168.1.61 External IP: 24.29.138.45 Now I want to be able to access RDP number 1 through Port 4000, but if I access Port 4001 it will connect to the server on port 4001; both using the same subdomain. The next issue is the fact that even though I know what the IP addresses are on the router for the virtualbox hosts through ifconfig it doesn't change the fact that they don't show up on the router. If anyone knows how to configure this to work please help me out because I've been racking my brain to the highest extent I can. Alright; here's an edit to clarify more; Sorry. My ports on the router are edited to forward Port 4000 on Internal IP 192.168.1.63 (My Ubuntu Internal IP address) Now when I go to my Router Home Page my VirtualBox Internal IP Address doesn't show on the attached device listings, so I set up port forwarding anyways to the VirtualBox Internal IP. My end goal is when I connect to mydomain.org and I connect through port 3389 it takes me to my host computers server, but if I put in mydomain.org and go through port 4000 it's going to redirect to my VirtualBox server; Is this even possible? Sorry; I'm trying to clarify the most I think I can I just don't know how else to explain my issue.

  • Windows 7 sharing folder from command line, selecting users and triggering the "Apply" of changes

    - by clintp
    I have a drive that doesn't get mounted until after I log in. (A Truecrypt thumbdrive device, and no, I'm not making it a "System Favorite" to get around this.) I'd like to construct a batch file to share it once I've gotten it mounted because the sharing info doesn't seem to stick through a reboot. From the GUI, I'd go into the folder Properties-Sharing. And then in Advanced Sharing I'd pick the name to share it as. And then under the "Share..." button I'd pick the users and the permissions I want to grant them. After "Apply" there's a pause -- I'm not sure what's happening here, but the dialog says "Sharing Items..." -- and then everything is okay. From the command line, I've done: net share MyFolder=F:\MyFolder cacls F:\MyFolder /G FirstUser:F cacls F:\MyFolder /G OtherUser:F And this almost works. I can see the share on the network then, but nobody has permissions to do anything. If I go into the GUI and change anything (and I can see my command-line changes in there already) and press "Apply" I get the: "Sharing Items.... This may take a few minutes" Dialog... and then Voila! It works. I get the "Your folder is shared" dialog with the command-line changes I made, along with the GUI change that I made to trigger the "Sharing Items..." dialog. Everything's peachy. Is a service being restarted? Which one? What's triggering the sharing to take effect? And -- more importantly -- how do I do it from the command line?

  • Can I use iptables on my Varnish server to forward HTTPS traffic to a specific server?

    - by Dylan Beattie
    We use Varnish as our front-end web cache and load balancer, so we have a Linux server in our development environment, running Varnish with some basic caching and load-balancing rules across a pair of Windows 2008 IIS web servers. We have a wildcard DNS rule that points *.development at this Varnish box, so we can browse http://www.mysite.com.development, http://www.othersite.com.development, etc. The problem is that since Varnish can't handle HTTPS traffic, we can't access https://www.mysite.com.development/ For dev/testing, we don't need any acceleration or load-balancing - all I need is to tell this box to act as a dumb proxy and forward any incoming requests on port 443 to a specific IIS server. I suspect iptables may offer a solution but it's been a long while since I wrote an iptables rule. Some initial hacking has got me as far as iptables -F iptables -A INPUT -p tcp -m tcp --sport 443 -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 443 -j ACCEPT iptables -t nat -A PREROUTING -p tcp --dport 443 -j DNAT --to 10.0.0.241:443 iptables -t nat -A POSTROUTING -p tcp -d 10.0.0.241 --dport 443 -j MASQUERADE iptables -A INPUT -j LOG --log-level 4 --log-prefix 'PreRouting ' iptables -A OUTPUT -j LOG --log-level 4 --log-prefix 'PostRouting ' iptables-save > /etc/iptables.rules (where 10.0.0.241 is the IIS box hosting the HTTPS website), but this doesn't appear to be working. To clarify - I realize there's security implications about HTTPS proxying/caching - all I'm looking for is completely transparent IP traffic forwarding. I don't need to decrypt, cache or inspect any of the packets; I just want anything on port 443 to flow through the Linux box to the IIS box behind it as though the Linux box wasn't even there. Any help gratefully received... EDIT: Included full iptables config script.

  • Solution to easily share large files with non-tech-savvy users?

    - by Tim
    Hey all, We've got a server setup at work which we'd like to use to exchange large files with known clients easily. We're looking into software to facilitate this, but somewhow typing "large file hosting" into Google gives questionable results.. ;) We've come up with the following requirements, and I hope any of you can points us in the direction of a solution that offers this functionality, or is malleable to our needs. Synchronization / revision management is of no concern, it's mostly single large (up to 1+ GB) file uploads & downloads we'll need. We'd like to make the downloads expire & be removed after a certain number of days / downloads, to limit the amount of cleanup we'd have to do. The data files exchanged sometimes hold confidential information, so the URLs generated should be random and not publicly visible. Our users are of the less technically savvy variety, so a simple webform would be best over a desktop client (because we also have to support a mix of operating systems). As for use of the system we'd either like to send out generated random URLs for them to upload their files, or have an easy way manage & expire users. Works on a linux (Ubuntu) server (so nothing .Net-related please) Does anyone know of software that fits the above criteria? We've already seen a few instances of this within the scientific community, but nothing we could use directly.. Best regards, Tim

  • 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?

  • Openbsd init script for ssh VPN tunnel

    - by manthis
    I have a server hosting SSH tunnels and Openbsd 4.5 clients connecting to it. Things work just fine but I am in the need of automating the connection from the client to the server. So that if the client is accidentally rebooted, then the connection initiates unattended. So it should be as straight forward as to include the ssh connection in an init script. However I have miserably failed to do so by including it to /etc/rc.local, which is the file I usually do this sort of things in. Right now I am using autossh to also restart the connection if necessary and the script that I put on /etc/rc.local follows: #!/bin/sh # # Example script to start up tunnel with autossh. # # This script will tunnel 2200 from the remote host # to 22 on the local host. On remote host do: # ssh -p 2200 localhost # # $Id: autossh.host,v 1.6 2004/01/24 05:53:09 harding Exp $ # ID=root HOST=example.com #AUTOSSH_POLL=600 #AUTOSSH_PORT=20000 #AUTOSSH_GATETIME=30 #AUTOSSH_LOGFILE=$HOST.log #AUTOSSH_DEBUG=yes #AUTOSSH_PATH=/usr/local/bin/ssh export AUTOSSH_POLL AUTOSSH_LOGFILE AUTOSSH_DEBUG AUTOSSH_PATH AUTOSSH_GATETIME AUTOSSH_PORT autossh -2 -f -M 20000 ${ID}@${HOST} The script detaches just fine when run manually so I just include it on /etc/rc.local as echo -n 'starting local daemons:' if [ -x /usr/local/sbin/autossh.sh ]; then echo -n 'ssh tunnel' /usr/local/sbin/autossh.sh fi echo '.' I have also tried calling it from /etc/hostname.tun0 in case there may be issues with /etc/rc.local not being called at the right time when network connections are ready, so I would use: inet 10.254.254.2 255.255.255.252 10.254.254.1 !/usr/local/sbin/autossh.sh Your input is highly appreciated.

  • SSL Handshake negotiation on Nginx terribly slow

    - by Paras Chopra
    I am using Nginx as a proxy to 4 apache instances. My problem is that SSL negotiation takes a lot of time (600 ms). See this as an example: http://www.webpagetest.org/result/101020_8JXS/1/details/ Here is my Nginx Conf: user www-data; worker_processes 4; events { worker_connections 2048; use epoll; } http { include /etc/nginx/mime.types; default_type application/octet-stream; access_log /var/log/nginx/access.log; sendfile on; keepalive_timeout 0; tcp_nodelay on; gzip on; gzip_proxied any; server_names_hash_bucket_size 128; } upstream abc { server 1.1.1.1 weight=1; server 1.1.1.2 weight=1; server 1.1.1.3 weight=1; } server { listen 443; server_name blah; keepalive_timeout 5; ssl on; ssl_certificate /blah.crt; ssl_certificate_key /blah.key; ssl_session_cache shared:SSL:10m; ssl_session_timeout 5m; ssl_protocols SSLv2 SSLv3 TLSv1; ssl_ciphers RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP; ssl_prefer_server_ciphers on; location / { proxy_pass http://abc; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } The machine is a VPS on Linode with 1 G of RAM. Can anyone please tell why SSL Hand shake is taking ages?

  • Process PHP files from a network share in a vmware virtual machine

    - by nhinkle
    As a testing environment, I have set up a vmware virtual machine running Windows Server 2008 R2. I have Apache and PHP installed (as part of the xampp package). I am doing the development outside of the VM, and so want Apache to serve PHP files from a VM shared folder (which appears as a network share in the VM). I have done this by creating an NTFS symbolic link in Apache's htdocs directory. I can access this directory from the browser, and plain-text files are readable. However, PHP fails to process files, instead returning the following error: Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'C:/xampplite/htdocs/path/to/file.php' (include_path='.;C:\xampplite\php\PEAR') in Unknown on line 0 It appears to be a permissions issue — PHP doesn't seem to be allowed to read the file to process it. However, Apache has no problem opening files in the directory. I cannot figure out how to give PHP the necessary permissions to process the file. Does anybody know of a way to make this work, or else another solution for getting the files into the VM automatically while I develop on the host machine?

  • Strange RDP / Remote Desktop problem

    - by John Landheer
    I'll try to be as specific as I can be: Server is running SBS 2008 R2 (with all updates) Server is connected to the internet Server has 2 NIC's, one is disabled Server is running RDP Service (accessible directly from the internet, I know, not as secure as it should be) Computers A and B are on the same local net. Computers A and B are both Windows 7. Users X and Y are both admins on the server Computer A can connect as user X to the server with mstsc Computer A can connect as user Y to the server with mstsc Computer B can connect as user X to the server with mstsc Computer B CANNOT connect as user Y to the server with mstsc! Error that username/password is incorrect. The last point is the problem, I get an authentication error. This used to work flawlessly for the last year. The server and desktops have been rebooted. EDIT: I tried: prefixing domain to the username prefixing the server computer name to the username change the password copy/paste the password from notepad to make sure it was correct I find it very strange.... EDIT: The computers are not on the same subnet as the server. The server is at my hosting provider. All computers as all users can reach the web app that is running on the server.

  • How should I deploy my JVM-based web application on ubuntu?

    - by Pieter Breed
    I've developed a web application using clojure/compojure (JVM based) and while developing I tested it using embedded jetty that runs on 0.0.0.0:8080. I would now like to deploy it to run on port 80 on ubuntu. I do dynamic virtual hosting, so any request for any host that arrives on port 80 should be handled by my application. The issues that worries me are: I can still run it embedded but I'm worried about running my app as root (needed for binding to port 80). I'm not sure if I can 'give up root' when in the JVM. Do I need to be concerned by this? besides, serving web applications is a known problem and I should be using known solutions for this (jetty or tomcat) but especially tomcat seems very heavy weight. Besides, I only have one application that listens to /* and does routing internally. (with compojure/ring). What I'm trying to say with this is that tomcat by default assigns WARs to subfolders which I don't want. So basically what I need is some very safe way of binding to port 80 on ubuntu that can with minimal interference send all requests to my app. Any ideas?
