  • PS2 Eyetoy Recording Quality

    - by Fire
    I have Ubuntu 12.04 LTS and a PS2 eyetoy "Namtai". Don't worry - this is not the sterotypical " how do I get my eyetoy working" question. My eyetoy works fine on Cheese, gucview and various other media software like VLC. However, It seems like I am capped by 25fps. If I recall, the eyetoy is much better than this (~60fps) but cannot find any way to fix this. The best program that I have have found is VLC because its advanced options allow you to change many settings but the framerate setting appears to have no effect. What software or settings can I use to take full advantage of my eyetoy? To give you the full information I wish to attach multiple eyetoys to the system and record from all of them. (Security software like motion and zoneminder, I couldn't get installed correctly on my system- so I haven't tried those yet). edit - I tried the same camera on a Windows system and the frame rate is much better in VLC compared to the Ubuntu system. Mind you with default settings in Windows VLC, the resolution isn't great. However, in Skype for example the resolution is amazing and the framerate is good. It seems there must be some settings I am missing somewhere because it doesn't appear to be a hardware problem...

  • Apache MaxClients reaching max and locking the server

    - by Rodrigo Sieiro
    Hi. I currently have an Apache2 server running with mpm-prefork and mod_php on a OpenVZ VPS with 512M real / 1024M burstable RAM (no swap). After running some tests, I found that the maximum process size Apache gets is 23M, so I've set MaxClients to 25 (23M x 25 = 575 MB, ok for me). I decided to run some load tests on my server, and the results left me puzzled. I'm using ab on my desktop machine requesting the main page from a wordpress blog. When I run ab with 24 concurrent connections, everything seems fine. Sure, CPU goes up, free RAM goes down, and the result is about 2-3s response time per request. But if I run ab with 25 concurrent connections (my server limit), Apache just hangs after a couple of seconds. It starts processing the requests, then it stops responding, CPU goes back to 100% idle and ab times out. Apache log says it reached MaxClients. When this happens, Apache keeps itself locked up with 25 running processes (they're all in "W" if I check server status) and only after the TimeOut setting the processes start to die and the server starts responding again (in my case it's set to 45). My question: is that expected behaviour? Why Apache just dies when it reaches MaxClients? If it works with 24 connections, shouldn't it work with 25, just taking maybe more time to respond each request and queueing up the rest? It sounds kinda strange to me that any kid running ab can alone kill a webserver just by setting the concurrent connections to the servers MaxClients.

  • IPFW not locking people out

    - by Cole
    I've had some brute-forcing of my ssh connection recently, so I got fail2ban to hopefully prevent that. I set it up, and started testing it out by giving wrong passwords on my computer. (I have physical access to the server if I need to unblock myself) However, it never stops me from entering passwords. I see in /var/log/fail2ban.log that fail2ban kicked in and banned me, and there's a ipfw entry for my IP, but I'm not locked out. I've changed the configuration around, and then tried just using the ipfw command myself, but nothing seems to lock me out. I've tried the following blocks: 65300 deny tcp from 10.0.1.30 to any in 65400 deny ip from 10.0.1.30 to any 65500 deny tcp from 10.0.1.30 to any My firewall setup has a "allow ip from any to any" rule after these though, maybe that's the problem? I'm using Mac OS 10.6 (stock ipfw, it doesn't seem to have a --version flag) Thanks in advance.

  • ESXi 4.0 Guests Locking up

    - by Brendan Sherwin
    I installed ESXi 4.0 on an HP Proliant g5 with a 64bit Xeon processor and took advantage of the free license as I work for a public school. I created two instances of server 2003 from scratch, one to be the DC, DHCP, the other to be a file server and DNS/DHCP backup. I had both guests up and running fine, setup my user accounts, transferred the data, etc etc. Once I joined a client machine to the domain, I would find that both of my Windows guests would lock up. Sometimes it would be for five or so minutes, once it was overnight. The "locked up" state means that as far I could tell, all services were stopped; dhcp no longer handed out IP's, DNS stopped working, I couldn't RDP into the server. The ESXi host, my HP server, was still running fine. VSphere was working, and I could look at the performance of the individual guests.I would try Powering off the hosts from inside VSPhere, and the hosts would start powering off, but get stuck at 95%, and stay that way, sometimes only for 10 minutes, others for hours. Several times I had to restart ESXi from it's console in order to restart my machines. Now, can anyone tell me what is happening, and how I can fix it, or take steps to prevent it? I hired a consultant to come take a look at it, someone who's experience and knowledge I trust, and he told me he had never seen anything like this ever before. He spoke to a friend of his who is VM certified, and he also said he had never heard of this issue. Thanks for your replies, and I'll do my best to respond ASAP. Currently, the server is powered off, and I've reinstituted my nine year old Server 2000 boxes, and I'm considering installing ESXi 3.5. Does anyone know a host created in 4.0 will work in 3.5? I'd really like to avoid having to rebuild those accounts! I know 4.0 works on this server, as I have another server in another school with the same exact hardware running 4.0 fine. Brendan

  • Postgres 9.0 locking up, 100% CPU

    - by Jake
    We are having a problem where our Postgres 9.0 server occasionally locks up and kills our webapp. Restarting Postgres fixes the problem. Here's what I've been able to observe: First, usage of one CPU jumps to 100% for a few minutes Disk operations drop to ~0 during this time Database operations drop to 0 (blocks and tuples per sec) Logs show during this time: WARNING: worker took too long to start; cancelled WARNING: worker took too long to start; cancelled No Queries in logs (only those over 200ms are logged) No unusually long-running queries logged before or during Then the second CPU jumps to 100% The number of postgres processes jumps from the usual 8-10 to ~20 Matched by a spike in Postgres Blocks per second (about twice normal) Logs show LOG: could not accept SSL connection: EOF detected Queries are running but slow Restarting postgres returns everything to normal Setup: Server: Amazon EC2 Large Ubuntu 10.04.2 LTS Postgres 9.0.3 Dedicated DB server Does anyone have any idea what's causing this? Or any suggestions about what else I should be checking out?

  • Stop Cisco AnyConnect from locking down the NIC

    - by Johannes Rössel
    Cisco's VPN crapclients (including the AnyConnect one) have the nasty habit of clobbering all NICs on the system you're using them. The old client had a checkbox in the connection options that allowed you to use other network interfaces while being connected while the AnyConnect client doesn't have any options at all, seemingly. But they both lock down the network interface they are using to connect to the VPN. Since I am forced to use AnyConnect to actually have an internet connection and I like to control a second computer at home via RDP (over the same network interface so far) this doesn't quite work out. With the old client IPv6 still worked just fine, though AnyConnect seems to dislike that as well now. Is there any way to still use the same network interface for LAN access? I actually don't really care about any possible security implications (which might be why Cisco does this) as it's my freaking internet connection and not a secure way of working from home. The trade-off is quite different :-)

  • Windows DFS - file locking & replication?

    - by Adam Salkin
    I'm in a small company that has offices on the east and west coasts of America and also various people working from their homes. There are Windows Servers already in the offices. I think that Microsoft Windows DFS will do what I want, but despite reading the web site, I'm really not sure, so I'm hoping that someone can confirm if it will do all the following: (For various personnel / political reasons I know that a proposal for a Microsoft Windows system has more chance of being accepted than any *nix system) Creation of a Folder so that any files in this folder will automatically be available on the servers in all the offices. When anyone opens up one of these shared files on any of servers, the copies on all the servers will automatically be locked. And when they close the file, the updates automatically get copied to the file on all the servers. VPN access to these folders for people working outside the offices. Bandwidth at the main offices varies from 6 Mb/s to 20Mb/s. Files are Excel / Word / AutoCAD ranging in size from 100KB to 4MB. Thank you.

  • Locking down a box on the web

    - by glowcoder
    I'm a Java developer who is looking to put a game on the web. I'm not much of a web or server guy, though, and frankly I seem a little lost at where I should start with putting something on the web. My application works fine on my machine, and I'm sure I can make it work fine on any box I put it on. But the security of that box is pretty important. If I sign up for a standard hosting package (let's say from GoDaddy or something) can I simply tell them "make port 12345 open for communication" and let them handle the rest of the security details? If I can't, what are the things I'm going to need to know to prevent my game server from getting hacked to shreds? (Links to solid resources fine by me!) Thanks!

  • Tying down a cloud by virtualizing everything and then locking VMs to real hardware as necessary

    - by tudor
    I'm looking for a cloud software solution that: Can run on both server and desktop machines; Virtualizes hardware and has the option of exposing each real machine to the cloud; Allows a VM to be "locked" to a set of real hardware capabilities and stay there until moved (e.g. a user's "real" desktop); Allows a VM to link to some types of devices elsewhere (e.g. USB/serial via ethernet); and Is geography-aware to control movement of VMs between real networks. I'm aware that this may be the holy grail of virtualization, and I've searched alot. Some solutions appear to meet some criteria but not others. Most cloud implementations appear to ignore real hardware, for example. I realise that this may be solved by using three different implementations in combination: A standard cloud server farm. A bare-metal network backup utility with PXEBoot. VNC and/or VDI. (VNC obviously would require the real hardware to be running.) This combination, however, has some serious drawbacks that I'd like to solve by treating it as one system. My explanation follows... I have a network of real servers and desktops in multiple locations. I've virtualized servers before using Virtualbox and that's worked quite well. I've even connected USB devices to VMs on servers. I would like to virtualize the desktops in all my offices to facilitate movement of desktops, remote access (e.g. VDI) and bare-metal backups. However, I know that there are problems with this. For example, some desktops have specific hardware (e.g. 3D graphics cards, USB devices, etc) that limit their mobility. Geographic constraints also limit movement in that VMs can be moved easily within offices, but transferring between offices is not always preferable. What I would like to find is a system that can virtualize everything from bare-metal easily by maintaining an abstraction layer on each client and server machine that exposes the hardware available and runs as a cloud. Then certain VMs would be "locked" to specific hardware (so that, e.g. the VM runs only on their own desktop.) This would be required for situations where speed is important (e.g. 3D graphics pass-through). In addition, abstracted low-speed devices (e.g. USB) could be piped from real hardware to a VM in the cloud. This is important since if a VM is taken down, another VM can connect to the real hardware for minimum downtime.

  • Problem IIS 7.0 Locking files durring upload

    - by viscious
    I am running a server 2008 with iis7 and the ftp addon on to iis 7.0 I have the ftp site configured and mostly working Except that about 70% of the time when transferring a file the upload will hang forever. If I disconnect the ftp client and reconnect and try to upload the same file I will get an error on the client saying the file is locked. I have to restart the ftp service to clear the lock. I fired up process explorer and did a search on the file in question and sure enough the ftp service has a lock on the file and it takes around 20 minutes to release the lock on its own (and sometimes longer). This lock stays around even after I disconnect the client. Like I said this only happens about 70% of the time, the other 30% of the time it goes through just fine. Things i have verified. -Not a firewall issue. Server is using passive port range 8000-9000 which is allowed on the firewall. -Not a nat issue, server has a globally rout-able ip address -all recommended/required updates installed I have 5 other servers in a very similar configuration and this is the only one i have problems with.

  • Multi Monitor setup goes crazy after locking/unlocking Vista machine

    - by Farseeker
    Give me a 10-blade quad-processor quad-core Opteron centre and ask me to configure failover/load balancing and I'd be happy to, but the following problem has got me completely stumped. My Vista Business Professional machine, running Ultramon, has three monitors attached. When I lock the machine (to go to the delicious cafe around the corner), the monitor layout stays correct. When I unlock it, I watch as all my screens flicker (as they are being re-configured), and Vista chooses some crazy layout for the monitors. The most recent one is below, but it's never consistant. Any ideas what might cause this? It's Vista Business, with UltraMon 3.0 (exiting Ultramon makes no difference).

  • Suscribers locking during snapshot replication

    - by remi_bourgarel
    Hi all :) Here is my architecture : I have a main server and 4 replica (the servers are synchronized with snapshot replication). The replication is working fine, except for one thing : during the replication a lot of SELECT request on one of the replica fail with a time-out. Here are my questions : Can I avoid these time-out ? If I can't : how can I detect the start and the end of the replication to redirect all the request on one of the replica to the main ? Thanks Sorry if you already answered to that kind of question but I couldn't find anything.

  • Login on VMWare XP guest machine keeps locking user AD account

    - by mark
    Environment: Windows 2003 AD Host: Windows 7 Pro VMWare Guest: Windows XP I use a normal user but I also have AD Admin rights (via another user). I use my AD account to login on the host as well on the aforementioned guest system. They don't share their profiles, so no problems here. I had reason to change my user (AD) password. When I did this, the guest was suspended but my user was logged in. A few days after my password change I resumed the guest. I was able to work but couldn't access networked mapped drives. I logged out and tried to log in again. At this point I realized that I initially was logged in with a user from a point before I changed my password. I logged in again with the new password, but then things went bad. I was able to successfully log in to my XP guest, however once that was completed, my AD user account got locked. This now also affected my user on the host. I was able to unlock the account, but there is still this problem: I log in via my new password into the guest and then my AD account gets locked. I'm successfully logged into the guest, but I can't access network shares from the AD server. If I don't unlock my account on the AD server, I will get further problems with my AD user. I tried multiple things, none worked: removed XP guest from AD, deleted all users, even my XP AD user profile on the guest, added machine to the AD, logged in - log in successful, account locked I resumed an older state of my guest (sometimes from the last year even) but the problem still persists. I tried this with disabled networking when the old machine state is resumed and so on, but no luck. It seems to me, although only my account is locked, this is somehow connected to the guest machine itself. I really want to avoid re-installation. This guest image was my old workstation which I virtualized once I moved to W7 pro and thus is still very valueable or me. I can work locally on the guest once logged in, but I can't access any network shares which is a problem. thanks

  • Outlook locking network connection/session?

    - by HaydnWVN
    Scenario: We have an 'automatic orders' machine sat in the corner running XP with Outlook 2003. Its job is to check for new emails on a specific account, when it encounters one it checks the e-mail body for specific wording to determine which customer it is from (using a macro), then it checks the attachment for specific order codes before parsing the attachment to create a .csv file (which is then e-mailed onto one of the sales team) before importing the .csv into our bespoke ERP/Sales Order system to create an order. Problem: Periodically the machine will have symptoms of a lost network connection (unable to connect to any network source). Sometimes after several days, sometimes over a week. Volume of emails/orders processed does not seem to be linked. Additional info: The machines .pst is stored on a mapped network location. The .csv created is stored on a mapped network location. This is a workgroup, not a domain. All network drives are Samba shares from an Ubuntu fileserver. Our bespoke system runs from a database (MySQL) Ubuntu server. Our troubleshooting so far: I have switched machines (previous was Win2000) with the same symptoms. Restarting the machine FIXES the problem. Closing Outlook and then end tasking an Outlook.exe background process FIXES the problem. If you close Outlook, without end taking the background process, outlook will not reopen (saying it cannot find the pst file & it will not open any network location). Does Outlook have some kind of 'max session' linking it to network activity that is not closing after a mail request? Could Auto-archive be causing this? Is there a tool to check/display what each outlook.exe process is doing? Have not found many ways to troubleshoot this yet, as it is so infrequent...

  • Locking down a server for shared internet hosting.

    - by Wil
    Basically I control several servers and I only host either static websites or scripts which I have designed, so I trust them up to a point. However, I have a few customers who want to start using scripts such as Wordpress or many others - and they want full control over their account. I have started to do the basics - like on php.ini, I have locked it down and restricted commands such as proc, however, there is obviously a lot more I can do. right now, using NTFS permissions, I am trying to lock down the server by running Application Pools and individual sites in their own user, however I feel like I am hitting brick walls... (My old question on Server Fault). At the moment, the only route I can think of is either to implement an off the shelf control panel - which will be expensive and quite frankly, over the top, or look at the Microsoft guide - which is really for an entire infrastructure, not for someone who just wants to lock down a few servers. Does anyone have any guides that can put me on the correct path?

  • Sound does not play when locking WinXP

    - by Christopher
    If I press the Windows-L combination to lock my PC the "Windows Logoff" sound does not play. It used to but at some point it stopped. I installed only trustworthy apps on my system and it is pretty clean so I don't think it is a virus. I checked the sounds in the control panel and "Windows Logoff" is set. Is there a sound associated with the key combination? Perhaps something in the registry? Any help is appreciated.

  • Help trying to figure out why IIS7 is crashing / locking up / denying connections

    - by Pure.Krome
    Hi folks, I've got a pretty busy website that is running on a single web front end machine, on W2K8 + IIS7. Every now and then - eg. maybe monday at 3am or something, then a few days later .. some early morning time .. then nothing for 2 weeks ... etc - the website fails to respond to any client connections. ie. no one can connect to the website. I can remote desktop to the machine, etc no probs. I restart the app pool (the website is running in intergrated mode), still nothing. I try and get a crash dump of the process (it's around 600 mb maybe even more) ... that fails after about a min of trying (and i have plenty of HD space). The only way to fix this issue, is to manually stop the www service and then start it again. The stopping takes a while (a minute?) while starting is nearly instant. I'm at a loss to figure out what part of my code is causing this. At first, I thought it might be a stack overflow because of some error that might be going to the error page, which in turn errors .. rinse repeat boom. But i've had a look at the error page and it feels ok. So, I'm hoping someone might be able to help and say how I can correctly get a proper dump of the IIS process so i can then do some more autopsy on it. I would email Tess Ferrandez (the goddess of crash debuging) but I thought I'd try here before I spam her. Can anyone have any suggestions to how I can figure out how to start to debug this issue?

  • Laptop Locking Up

    - by David
    I am having a very weird issue on a Lenovo W510 laptop. It will lock up randomly. I have had it lock up during post, during the boot-up of Linux, during login, and after the login. The following are tests that I have performed on the laptop. I ran memtest I took out the extra memory module. I swapped the HDD with another HDD that had Windows 7 on it. (It BSOD'd, and before anyone could possibly read the error line, it restarts.) I tried taking the battery out and booting with only the Power cord. The only other options I can think of the problem being are the motherboard or the PSU. If anyone has any advice, I appreciate it. If not, the HP guy will be here in a few days to fix it. I would just love to call them up and tell them that the service is no longer needed.
