  • How to boot linux direct to application on console with no login

    - by amanda
    I have a need to start an application on bootup on the linux console and I do not have a need for any type of login or security. I do not need any ALT-F1,F2,etc virtual consoles but I would like to allow SSH access via the network port for debugging, loading, etc. The application is a SDL graphics program running with fbcon as the SDL_VIDEODRIVER if that matters. I'm currently using Fedora 10 and 12 but any distro that supports SDL using the fbcon framebuffer would be acceptable.

  • What strategy do you use for package naming in Java projects and why?

    - by Tim Visher
    I thought about this awhile ago and it recently resurfaced as my shop is doing its first real Java web app. As an intro, I see two main package naming strategies. (To be clear, I'm not referring to the whole 'domain.company.project' part of this, I'm talking about the package convention beneath that.) Anyway, the package naming conventions that I see are as follows: Functional: Naming your packages according to their function architecturally rather than their identity according to the business domain. Another term for this might be naming according to 'layer'. So, you'd have a *.ui package and a *.domain package and a *.orm package. Your packages are horizontal slices rather than vertical. This is much more common than logical naming. In fact, I don't believe I've ever seen or heard of a project that does this. This of course makes me leery (sort of like thinking that you've come up with a solution to an NP problem) as I'm not terribly smart and I assume everyone must have great reasons for doing it the way they do. On the other hand, I'm not opposed to people just missing the elephant in the room and I've never heard a an actual argument for doing package naming this way. It just seems to be the de facto standard. Logical: Naming your packages according to their business domain identity and putting every class that has to do with that vertical slice of functionality into that package. I have never seen or heard of this, as I mentioned before, but it makes a ton of sense to me. I tend to approach systems vertically rather than horizontally. I want to go in and develop the Order Processing system, not the data access layer. Obviously, there's a good chance that I'll touch the data access layer in the development of that system, but the point is that I don't think of it that way. What this means, of course, is that when I receive a change order or want to implement some new feature, it'd be nice to not have to go fishing around in a bunch of packages in order to find all the related classes. Instead, I just look in the X package because what I'm doing has to do with X. From a development standpoint, I see it as a major win to have your packages document your business domain rather than your architecture. I feel like the domain is almost always the part of the system that's harder to grok where as the system's architecture, especially at this point, is almost becoming mundane in its implementation. The fact that I can come to a system with this type of naming convention and instantly from the naming of the packages know that it deals with orders, customers, enterprises, products, etc. seems pretty darn handy. It seems like this would allow you to take much better advantage of Java's access modifiers. This allows you to much more cleanly define interfaces into subsystems rather than into layers of the system. So if you have an orders subsystem that you want to be transparently persistent, you could in theory just never let anything else know that it's persistent by not having to create public interfaces to its persistence classes in the dao layer and instead packaging the dao class in with only the classes it deals with. Obviously, if you wanted to expose this functionality, you could provide an interface for it or make it public. It just seems like you lose a lot of this by having a vertical slice of your system's features split across multiple packages. I suppose one disadvantage that I can see is that it does make ripping out layers a little bit more difficult. Instead of just deleting or renaming a package and then dropping a new one in place with an alternate technology, you have to go in and change all of the classes in all of the packages. However, I don't see this is a big deal. It may be from a lack of experience, but I have to imagine that the amount of times you swap out technologies pales in comparison to the amount of times you go in and edit vertical feature slices within your system. So I guess the question then would go out to you, how do you name your packages and why? Please understand that I don't necessarily think that I've stumbled onto the golden goose or something here. I'm pretty new to all this with mostly academic experience. However, I can't spot the holes in my reasoning so I'm hoping you all can so that I can move on. Thanks in advance!

  • Running Safari from the command line adds current directory to the URL

    - by Charles Anderson
    I am trying to run the Safari browser (on Mac OS 10.4) from the command line, as follows: /Applications/Safari.app/Contents/MacOS/Safari http://localhost/dev/myfile.html However, Safari starts up and tries to access file:///Users/charlesanderson/scripts/http://localhost/dev/myfile.html /Users/charlesanderson/scripts happens to be my current directory. Can someone explain why Safari does this? Firefox is much better behaved?

  • nginx reverse proxy subdomain is redirecting

    - by holtkampw
    So I have a frontend nginx server which will proxy to several other nginx servers (running Passenger for Rails apps). Here's the part of the frontend nginx config in question: server { listen 80; server_name git.domain.com; access_log /server/domain/log/nginx.access.log; error_log /server/domain/log/nginx_error.log debug; location / { proxy_pass http://127.0.0.1:8020/; 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_max_temp_file_size 0; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } server { listen 80; server_name domain.com; access_log /server/domain/log/nginx.access.log; error_log /server/domain/log/nginx_error.log debug; location / { proxy_pass http://127.0.0.1:8000/; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X_FORWARDED_PROTO https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } Finally here's the backend for git.domain.com: server { listen 8020; #server_name localhost; root /server/gitorious/gitorious/public/; passenger_enabled on; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X_FORWARDED_PROTO https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } So here's the problem. When I type in git.domain.com, my gitorious install will redirect to domain.com. It works perfect there, but it ignores the subdomain. At first I thought it was the server_name construct. I have tried git.domain.com, domain.com, localhost, and currently none. Any ideas?

  • Quantifying the effects of partition mis-alignment

    - by Matt
    I'm experiencing some significant performance issues on an NFS server. I've been reading up a bit on partition alignment, and I think I have my partitions mis-aligned. I can't find anything that tells me how to actually quantify the effects of mis-aligned partitions. Some of the general information I found suggests the performance penalty can be quite high (upwards of 60%) and others say it's negligible. What I want to do is determine if partition alignment is a factor in this server's performance problems or not; and if so, to what degree? So I'll put my info out here, and hopefully the community can confirm if my partitions are indeed mis-aligned, and if so, help me put a number to what the performance cost is. Server is a Dell R510 with dual E5620 CPUs and 8 GB RAM. There are eight 15k 2.5” 600 GB drives (Seagate ST3600057SS) configured in hardware RAID-6 with a single hot spare. RAID controller is a Dell PERC H700 w/512MB cache (Linux sees this as a LSI MegaSAS 9260). OS is CentOS 5.6, home directory partition is ext3, with options “rw,data=journal,usrquota”. I have the HW RAID configured to present two virtual disks to the OS: /dev/sda for the OS (boot, root and swap partitions), and /dev/sdb for a big NFS share: [root@lnxutil1 ~]# parted -s /dev/sda unit s print Model: DELL PERC H700 (scsi) Disk /dev/sda: 134217599s Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 63s 465884s 465822s primary ext2 boot 2 465885s 134207009s 133741125s primary lvm [root@lnxutil1 ~]# parted -s /dev/sdb unit s print Model: DELL PERC H700 (scsi) Disk /dev/sdb: 5720768639s Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 34s 5720768606s 5720768573s lvm Edit 1 Using the cfq IO scheduler (default for CentOS 5.6): # cat /sys/block/sd{a,b}/queue/scheduler noop anticipatory deadline [cfq] noop anticipatory deadline [cfq] Chunk size is the same as strip size, right? If so, then 64kB: # /opt/MegaCli -LDInfo -Lall -aALL -NoLog Adapter #0 Number of Virtual Disks: 2 Virtual Disk: 0 (target id: 0) Name:os RAID Level: Primary-6, Secondary-0, RAID Level Qualifier-3 Size:65535MB State: Optimal Stripe Size: 64kB Number Of Drives:7 Span Depth:1 Default Cache Policy: WriteBack, ReadAdaptive, Direct, No Write Cache if Bad BBU Current Cache Policy: WriteThrough, ReadAdaptive, Direct, No Write Cache if Bad BBU Access Policy: Read/Write Disk Cache Policy: Disk's Default Number of Spans: 1 Span: 0 - Number of PDs: 7 ... physical disk info removed for brevity ...

  • Using Amazon S3 for multiple remote data site uploads, securely

    - by Aitch
    I've been playing about with Amazon S3 a little for the first time and like what I see for various reasons relating to my potential use case. We have multiple (online) remote server boxes harvesting sensor data that is regularly uploaded every hour or so (rsync'ed) to a VPS server. The number of remote server boxes is growing regularly and forecast to keep growing (hundreds). The servers are geographically dispersed. The servers are also automatically built, therefore generic with standard tools and not bespoke per location. The data is many hundreds of files per day. I want to avoid a situation where I need to provision more VPS storage, or additional servers every time we hit the VPS capacity limit, after every N server deployments, whatever N might be. The remote servers can never be considered fully secure due to us not knowing what might happen to them when we are not looking. Our current solution is a bit naive and simply restricts inbound rsync only over ssh to known mac address directories and a known public key. There are plenty of holes to pick in this, I know. Let's say I write or use a script like s3cmd/s3sync to potentially push up the files. Would I need to manage hundreds of access keys and have each server customized to include this (do-able, but key management becomes nightmarish?) Could I restrict inbound connections somehow (eg by mac address), or just allow write-only to any client that was running the script? ( i could deal with a flood of data if someone got into a system? ) having a bucket per remote machine does not seem feasible due to bucket limits? I don't think I want to use a single common key as if one machine is breached then potentially, a malicious hack could get access to the filestore key and start deleting for ll clients, correct? I hope my inexperience has not blinded me to some other solution that might be suggested! I've read lots of examples of people using S3 for backup, but can't really find anything about this sort of data collection, unless my google terminology is wrong... I've written more than I should here, perhaps it can be summarised thus: In a perfect world I just want to have one of our techs install a new remote server into a location and it automagically starts sending files home with little or no intervention, and minimises risk? Pipedream or feasible? TIA, Aitch

  • Windows Hosting

    - by Sid Momin
    What's a good hosting service for the following? I need to set up a Windows development server, IIS and SQL server. We will be developing with Visual Studio. We also need to control our project with SVN. We're probably looking for a VPS, but we definitely need administrator access and the ability to install programs such as (whatever Windows uses for) SVN. Price does matter, because we're a 4 man operation. Thanks

  • Why won't these permissions do what I wish?

    - by Chris B.
    I am trying to make my folder owned by "apache" and then chmod that folder so that only the owner and group can access it. I am trying to do this to keep visitors from executing user-uploaded files directly. Here are the commands I am using: chown -R apache uploads chmod -R 770 uploads Source: http://www.mysql-apache-php.com/fileupload-security.htm Instead it seems that although it is keeping visitors from seeing the files, it is not allowing apache to serve them. Do you have any ideas?

  • Can Debian identify rarely used packages?

    - by Norman Ramsey
    I'd like to find a tool that could tell me which Debian packages on my system have been rarely or never used, perhaps by looking at file lists and access times. This is to find candidates for deletion from my nearly full hard drive. I'm not very well informed about the rich ecosystem of desktop GUI tools (I use aptitude); does anyone know if one of those tools, or any other tool, can identify how recently a package has been used?

    It is possible to access any of the new shortcut keys found in Windows 8 via RDP, such as those in the accepted answer in What are the new shortcuts for Windows 8?, without having to redirect all Win key combinations through to the remote session. I am using both local and remote at the same time, and so would prefer alternate shortcuts for the remote session. Such as the basic ones listed at the Microsoft site here, and for example Alt+Home will return you to the Start screen. What about the more interesting shortcuts?

Now, I don't want to have to log in to a server every time I want to access this client...is there a way to run the Remote Control Viewer client on my desktop OS so I can take remote control of systems rather than having to remote in from the server? This seems like very basic functionality...but I haven't been able to figure it out thus far.
