  • Is it possible to edit the web pages in the Profile Manager (OSX Lion Server) user portal?

    - by sglantz
    When setting up Profile Manager in Lion Server, there are a few web pages that are generated for web management of both devices and profiles. Is it possible to edit these pages in any way? I am just looking to customize the look and feel without changing the functionality. If editing is possible, where are these pages stored? I have looked through the /Library/Server/ProfileManager and /Library/Server/Web folders without any luck. This is one particular page I would like to edit. Ideally I would like to be able to edit the HTML directly. I am looking to match the page's style with a variety of other pages hosted on the server.

  • Unix users and permissions and how they interact with web files.

    - by Columbo
    Hello, When you issue the command ls in Linux you get this sort of thing: drwxr--r-- 1 fred editors 4096 drafts -rw-r--r-- 1 fred editors 30405 file1.php -r-xr-xr-x 1 fred fred 8460 file2.php I know that the rwxrwxrwx are the read, write and execute permissions for the current user. And I think I know that 'fred' is the user who owns the file. So I assume fred can write to file1 but no one else can. But what is the extra bit 'editors' and what is the difference between file1 and file2 with respect to one having an ownership of 'fred editors' and the other 'fred fred'? Also if a web user connects to one of the files, what is their user name and where is this decided? If the server decided that user connecting from the web was going to be fred, does this mean any web user could write to file1? Any information welcomed, I am resaerching this but just getting confused. Thanks

  • RabbitMQ - How I do configure servers for zero-downtime upgrades?

    - by Terence Johnson
    Having read through the docs and RabbitMQ in Action, creating a RabbitMQ cluster seems straightforward enough, but upgrading or patching an existing RabbitMQ cluster seems to require the whole cluster to be restarted. Is there a way to combine clustering, shovel, federation, and load balancing to make a rolling upgrade possible without losing queues or messages, or have I missed something slightly more obvious?

  • SQL Server 2008 Web edition in a hosting plan?

    - by Simon
    Do any hosting companies offer SQL Server 2008 Web edition in a hosting plan. GoDaddy for instance offers Standard/Enterprise editions which raise the price by $200 or so a month. I've tried a few hosting companies and can't find the web edition available. Why not? The web edition is supposed to be only $15/month - but I was hoping to be able to get this pricing through a dedicated server and not have to go off and separately get the licensing. I don't even know if its possible to buy just one copy!?

  • collectd:Monitoring server not showing clients

    - by Quintin Par
    I have setup a monitoring server with the following setup. <Plugin network> Listen "0.0.0.0" "25826" </Plugin> Now my clients are sending data to the monitoring server(verified through tcpdump). Even the collection folder shows that the data is being dumped /var/lib/collectd/rrd [ec2-user at x rrd]$ ll total 4 drwxr-xr-x 11 root root 4096 Nov 20 17:53 x-web-1.y.com [ec2-user at x rrd]$ I have also verified with find . -mmin 1 to see if its being constantly updated.

  • Does Apache2 Configured as ReverseProxy Hide Cookies Set by Backend Servers?

    - by Ianthe
    I use Apache 2.2.16 as Reverse Proxy. For a static website, I don't have any issues. However, when began to use cookies, I've noticed that cookies are not being sent to the client. Here's a snippet of my config: <VirtualHost *:80> ServerName app.somewhere.com:80 ServerAlias app ProxyRequests Off ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /app http://10.x.x.x/app ProxyPassReverse /app http://10.x.x.x/app <Location /> Order allow,deny Allow from all </Location> </VirtualHost> But when I try to access the app server directly, I receive the cookies ok. Is this an expected behaviour for Apache2? I'm using HAProxy for another application that sends cookies to the client and I get all of them.

  • sudoer scheme for a web developer that retains future control of a server?

    - by Tchalvak
    Background I have a server that I'm looking to set up, and provide access to another web developer. I don't want to put many constraints on him, though I wouldn't mind isolating the site that he'll be developing from others on the server that I will develop. The problem Mainly what I want is to make sure that I retain control over the server in the future. I want to reserve the ability to create/promote/demote and other administrative functions that don't deal with web software. If I make him an admin, he can sudo su - and become root and remove root control from me, for example. What is a good setup for the sudoers file so that he can do things like: *install software (through apt-get) restart apache access mysql configure mysql/apache reboot edit web development configuration type files in /etc * And can't do things like: take away other admin permissions change the root password have control over other security/administrative functions Example sudoer files that accomplish something like that could be useful, I'm sure that people have needed to do this before.

  • Can a Windows 2003 Active Directory server act as a NTP server?

    - by Rob Nicholson
    Within our LAN, there are two Windows 2003 servers with the Active Directory role. Both these servers have the time service configured to query NTP servers on the internet for the accurate time. That works fine. I've just installed XenServer v5.6 and it's asked me for the IP address of an NTP server. Without tweaking the firewall, I cannot configure this server to reference an internet based NTP server. But can I configure it to use the IP address of the internal AD servers, i.e. do AD servers also act as NTP servers to other computers? Thanks, Rob.

  • What Triggers a syncronization between Exchange 2007 Mail Store and Edge Servers?

    - by BillN
    We are using Exchange 2007 for our mail. In our configuration, we need to add an alias to each users mailbox. When we do, the Edge server, another Exchange 2007 box, will reject the alias with a User Unknown error until the next morning. I seem to recall that in Exchange 2003, you could force an update from the Management console, but I can not find a way in 2007. It is obvious that a sync job is scheduled to run each night, but I cannot find it.

  • If I use openvpn, can vpn servers monitor my usernames/passwords?

    - by Duff
    Openvpn uses a type of encryption similar to ssl. This seems to suggest that even if I choose an incredibly shady VPN server, then my content will be secure. That is, the VPN server will be able to monitor what websites I patronize, but not the actual data I transfer. That said, I am not an expert at this type of thing. I wanted, therefore, to make sure that I understand correctly. Is it true that if I use openvpn that my username/passwords are secure, even if the VPN is untrustworthy? If not, why? (And how, if at all, can it be fixed?) Examples of things that I don't know much about that may (or may not! I honestly don't know much about this.) be related to my question are: DNS leakage, IPv6, tracking cookies, browser plugins and websites that don't support https.

  • Web service not accessible from behind corporates firewalls - how come?

    - by Niro
    We run a Saas serving a widget which is embedded in customer websites. The service include static javascript code hosted on amazon S3 and dynamic part hosted on EC2 with Scalr (using scalr name servers). We received some feedback from users behind corporate firewalls that they cant access our service (while they can access the sites including the widget). This does not make sense to me since the service is using normal http calls on port 80 and our URL is quite new without any reason to be banned by firewalls. My questions are: 1. Why is the service is not accessible and what can I do about it? 2. Is it possible that one of the following is blocked by corporate firewalls: Amazon s3, the dynamic IP address provided by amazon, Scalr name servers. Any other possible reasons, way to check them and remedies for this? Thanks!

  • Naming standard for additional A records/IP addresses for IIS servers?

    - by serialhobbyist
    When you're adding another IP address to and IIS server, what naming standards do you use for the A records? Background: I've a bunch of sites on an IIS server which use (CNAME'd) host-headers and a single IP address. Server names (and A records) adhere to unfriendly (as in difficult-to-remember) naming standards whereas CNAMEs, and therefore host-headers, can be friendly. Now I've a need for several SSL certificates for different sites. I was thinking about using an additional IP address for each to-be-SSL'd site but still using friendly CNAMEs. So then I come to what to call the A record. What do you do? Related to this question.

  • What's more cost effective, Hosting your web startup on Foss or Windows?

    - by user37899
    Hi, Not coming from the windows world, I'm confused about licensing. I think my knowledge may be out of date. Before we gave up with windows web servers (IIS 2), we used to have to pay Client Access licence's. This worked out quite expensive. Is it cheaper to host 1000's of users on Windows than use Free open source software tools? http://serverfault.com/questions/124329/network-load-balancing-efficience-and-limits. This post suggests I can pay $15 a month, for unlimited users. I certainly hope that this is unbiased view, I am a professional and use the right technology for the right job. I hope i am not feeling the wrath of a windows (or linux for that matter) fanboy. Perhaps a Microsoft certified Licensing person can clear this up. Should i be recommending to startups windows servers and products over lamp? Cheers!

  • How to replicate a windows servers (IIS,Files,ConfigurationState)?

    - by Geo
    Maybe a better question is: What is the closest competitor for DoubleTake? I am looking to replicate a windows production server in case it fails have a immediate backup. Any idead? NOTE 1: I forget to add that this server is on the EC2 Amazon Cloud. NOTE 2: The main situation we have is recreating the configuration settings like IIS, FTP Server, SQL Server, SVN Server. NOTE 3: So far I have been giving three options as answers for my original question: AppAssurance -- After talking to their sales team they do not support Amazon as cloud provider. Basically there is a technical need to be able to reboot from a disk or similar media. So ESX Virtual machine environment will work, but not the EC2. Acronis -- which works as a backup in ghost style. This will work for other type of scenarios. Use the Amazon EC2 API -- This option is ideal, but only works if you are developing a cloud application rather than hosting a regular application in a cloud scenario. This means that I am still looking for the answer. Any other ideas.

  • How to invalidate nginx reverse proxy cache in front of other nginx servers?

    - by Olivier Lance
    I'm running a Proxmox server on a single IP address, that will dispatch HTTP requests to containers depending on the requested host. I am using nginx on the Proxmox side to listen to HTTP requests and I am using the proxy_pass directive in my different server blocks to dispatch requests according to the server_name. My containers run on Ubuntu and are also running a nginx instance. I'm having troubles with caching on a particular website that is fully static: nginx keeps on serving me stale content after files updates, until I: Clear /var/cache/nginx/ and restart nginx or set proxy_cache off for this server and reload the config Here's the detail of my configuration: On the server (proxmox): /etc/nginx/nginx.conf: user www-data; worker_processes 8; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; use epoll; } http { ## # Basic Settings ## sendfile on; #tcp_nopush on; tcp_nodelay on; #keepalive_timeout 65; types_hash_max_size 2048; server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; client_body_buffer_size 1k; client_max_body_size 8m; large_client_header_buffers 1 1K; ignore_invalid_headers on; client_body_timeout 5; client_header_timeout 5; keepalive_timeout 5 5; send_timeout 5; server_name_in_redirect off; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; gzip_vary on; gzip_proxied any; gzip_comp_level 6; # gzip_buffers 16 8k; gzip_http_version 1.1; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; limit_conn_zone $binary_remote_addr zone=gulag:1m; limit_conn gulag 50; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } /etc/nginx/conf.d/proxy.conf: proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_hide_header X-Powered-By; proxy_intercept_errors on; proxy_buffering on; proxy_cache_key "$scheme://$host$request_uri"; proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=cache:10m inactive=7d max_size=700m; /etc/nginx/sites-available/my-domain.conf: server { listen 80; server_name .my-domain.com; access_log off; location / { proxy_pass http://my-domain.local:80/; proxy_cache cache; proxy_cache_valid 12h; expires 30d; proxy_cache_use_stale error timeout invalid_header updating; } } On the container (my-domain.local): nginx.conf: (everything is inside the main config file -- it's been done quickly...) user www-data; worker_processes 1; error_log logs/error.log; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; #tcp_nopush on; keepalive_timeout 65; gzip off; server { listen 80; server_name .my-domain.com; root /var/www; access_log logs/host.access.log; } } I've read many blog posts and answers before resolving to posting my own questions... most answers I can see suggest setting sendfile off; but that didn't work for me. I have tried many other things, double checked my settings and all seems fine. So I'm wondering whether I am not expecting nginx's cache to do something it's not meant to...? Basically, I thought that if one of my static files in my container was updated, the cache in my reverse proxy would be invalidated and my browser would get the new version of the file when it requests it... But I now have the sentiment I misunderstood many things. Of all things, I now wonder how nginx on the server can know about a file in the container has changed? I have seen a directive proxy_header_pass (or something alike), should I use this to let the nginx instance from the container somehow inform the one in Proxmox about updated files? Is this expectation just a dream, or can I do it with nginx on my current architecture?

  • How to choose a web server for a Python application?

    - by Phil
    Information and prerequisites: I have a project which is, at its core, a basic CRUD application. It doesn't have long running background processes which it forks at the beginning and talks to later on, nor does it have long running queries or kept alive connection requirements. It receives a request, makes some queries to the database and then responds. In order to serve static files and cachable files fast, I am going to use Varnish in all cases. Here is my question: After reading about various Python web application servers, I have seen that they all have their "fans" for certain, usually "personal" reasons, which got me confused since each usecase differs from the next. How can I learn about the core differentiating factors of Python web servers (in order) to decide how suitable they are for my project and if one would be better than the other? What are your (technically provable) thoughts on the matter? How should I choose a Python web server? Thank you.

  • Is this common practice for disk quotas on virtual dedicated servers?

    - by Louis
    Hello, I was a bit surprised when I purchased a VPS with 15GB of storage to find that am left with very little space after Windows' 13GB footprint. I can't even install SQL Server. Tech support is saying this is normal. I know that if they felt like it they could remove Windows from the quota or adjust it accordingly. Is this a common practice or should I further pursue the issue with customer service?

  • Do you use different wallpaper or background colors for dev, production servers?

    - by crosenblum
    I want to make it easier to distinguish between server's connected via rdp, without draining resources too much. Do any of you use any wallpaper, and if so, can you show any examples? Or do you use a custom desktop background color? Or do you use something like bginfo? Are there any good wallpaper sites, specifically for server wallpaper? To help distinguish what server you are on... Thanks..

  • Best NIC config when virtual servers need iSCSI storage?

    - by icky2000
    I have a Windows 2008 server running Hyper-V. There are 6 NICs on the server configured like this: NIC01 & NIC02: teamed administrative interface (RDP, mgmt, etc) NIC03: connected to iSCSI VLAN #1 NIC04: connected to iSCSI VLAN #2 NIC05: dedicated to one virtual switch for VMs NIC06: dedicated to another virtual switch for VMs The iSCSI NICs are used obviously for storage to host the VMs. I put half the VMs on the host on the switch assigned to NIC05 and the other half on the switch assigned to NIC06. We have multiple production networks that the VMs could appear on so the switch ports that NIC05 & NIC06 are connected to are trunked and we then tag the NIC on the VM for the appropriate VLAN. No clustering on this host. Now I wish to assign some iSCSI storage direct to a VM. As I see it I have 2 options: Add the iSCSI VLANs to the trunked ports (NIC05 and NIC06), add two NICs to the VM that needs iSCSI storage, and tag them for the iSCSI VLANs Create two additional virtual switches on the host. Assign one to NIC03 and one to NIC04. Add two NICs to the VM that needs iSCSI storage and let them share that path to the SAN with the host. I'm wondering about how much overhead the VLAN tagging in Hyper-V has and haven't seen any discussion about that. I'm also a bit concerned that something funky on the iSCSI-connected VM could saturate the iSCSI NICs or cause some other problem that could threaten storage access for the entire host which would be bad. Any thoughts or suggestions? How do you configure your hosts when VMs connect direct to iSCSI?

  • Why are email transfers between mail servers often not encrypted? Why aren't users warned about it?

    - by AmV
    Users can often choose if they want to access their email provider (such as Gmail) using a secure channel (e.g. using HTTPS). However, to the best of my knowledge, when it comes to mail-server-to-mail-server communications, most emails are still transferred in plain text and not encrypted, making it possible to anybody on the network to read their content. Are there any technologies that give the user some guarantees that his emails are sent securely from end to end ? Why not let the user know when encryption is not supported and let him choose if he wants his email to be still delivered ?
