  • 550 relay not permitted

    - by Nick Swan
    Hi, we are using Fogbugz on our server to do customer support emails. Occasionally though we get errors coming back when sending emails of: 550 relay not permitted This seems to happen at random though, sometimes sending an email to a person works, next time to the same person it'll bounce back. I've tried setting up reverse DNS with the server host and creating the SPF record in GoDaddy but we still get some of these errors. Is there anything else I can do, and is there a way of testing these are actually configured correctly? Many thanks, Nick

  • Interpreting Munin graphs showing available entropy and MySQL slow queries in sync

    - by user64204
    We're experiencing performance issues on our website, and after reviewing our munin graphs, the only metrics we've found in sync are Available entropy and MySQL slow queries, with the latter influenced by our number of logged in users: Based on the wikipedia entropy page, my understanding is that entropy is the amount of randomness (here measured in bytes) that the system can use for various tasks, mainly cryptography and functions that require random input. Since the peaks in available entropy and MySQL slow queries are occurring in sync and at regular interval, that the number of MySQL slow queries is proportional to our number of Drupal users whereas the peaks in available entropy seem to be much more constant and less proportional to these 2 metrics, we're thinking available entropy is the reflect of a root cause which, combined with the traffic to our website, is causing those slow queries (and not the opposite, slow queries influencing the entropy). Accordingly: Q: What underlying problem do you think could cause regular peaks in available entropy that could have an influence on MySQL's ability to process queries?

  • Get source and destination of outbound traffic in pfSense

    - by maxsilver
    I'm looking at the traffic graph in pfSense (Version 1.2.2), which we're using as a router / NAT / ect on our network. Recently, I'm seeing a sudden, constant spike of 15 - 30kbps traffic outbound, that is unusual for our network (normally its below 2kbps, we're mostly all inbound traffic) Is there any way to determine what the source of this traffic is, or where it's going? (Just an internal IP address for source, and external IP address for destination would be all I need) I've already tried switching the traffic graph to 'LAN' and watching the host list on the right side, but it seems ... flakey. The numbers it shows seem to fade in and out at random, and the values never add up to anywhere near the graph values. I'm not allowed to post the image, but a photo is available at - http://imgur.com/QYjKI.png

  • Computer Randomly Restarts (no crash dump)

    - by Bruno Charters
    Hey everyone this is my first time here, so, my computer got pulled out of his place the other day by accident and it never got back to working decently ever again. I just stopped using it because everytime i power it on, it restarts. Some times it doesn't even reach the desktop, others it even allows me to run a game or something. It gets really random. Today i was trying my last attempt before sending it to fix and it ran fine for 40 minutes but as i tried to run a game the screen got really messeud up full of colorful lines and stuff and i'm assuming it had to do with the graphics card. Altho, my question is, what can be causing all this restart thingie? Can it be just the Power Supply failing me and hence, not giving enough power to make the graphic card go for instance? My computer specs are: Motherboard: Asus P5KPL - AM CPU: Intel QuadCore 2.33 ghz Graphic Card: Nvidia GeForce GTS260 Ram: 2x2gb ddr2 Power Supply: Nox Urano 500W Thanks in advance, Bruno Charters

  • How to check that image sizes are ok or not

    - by Goran
    I am having many image files in one folder. Mostly there are jpg, but some png, bmp, gif, tif also (but jpg is most important if others are not possible). There are also many xml files in same folder with same names as image files are having. So there is something like this: 1.jpg, 1.xml, a.png, a.xml, 3g.bmp, 3g.xml... All xml files are having only 1 line: <IMGRES WIDTH="1234" HEIGHT="567" /> (of course numbers are not same). I am looking for some easy way to check all image sizes and confirm if they are same as in xml or not. So I want output like: imagename, xmlwidth x xmlheight, realwidth x realheight, match/error Is this possible in only Windows with no other software installed?

  • Can I make the Courier email server use a non-default salt for passwords?

    - by Vasiliy Stavenko
    I'm setting up email server for the first time and confused with strange thing. I have several user accounts which stored in previous server. Passwords for this accounts are in plain text. But I want to create crypts for them. MySQL (where my users will be stored) have function encrypt(passwd, salt). If no salt given used random value. I discovered that Courier uses one certain salt and crypted all passwords with it. So the task done. But I'd like to know if there's a way to define my own salt for my pop3 server?

  • Free Google Docs alternative compatible with Opera

    - by f4k3
    Well gDocs isn't working ok, too many bugs and it's pretty slow (especially when saving documents). I have tried several alternatives: - Zoho - they say it's not compatible with Opera and it;s true - you even can't CTRL+V text - Buzzword - it's really slow, and some functions don't work properly (on all browsers) for example "increase indent" increases a random text indent - Etherpad - was taken over by google and is shut down - Peepel - it's a cool thing, almost a free virtual desktop in a browser but it's buggy - a saved a document, tried to open it end an error occured. the document was lost - OpenGoo - went commercial At the moment I'm testing ThinkFree Online - it'a a bit slow (Java :P) and some minor things don't work (like drag a toolbar) but it has cool functionalities (almost like OpenOffice! which I use at home), it actually works with opera (create, save, edit document). Maybe I'll try Scribd but is it a office/share platform? any other worth trying??

  • Why does Task Scheduler NOT re-run successfully completed tasks

    - by Teo
    I am using Task Scheduler on Windows 2008 x64. I have 3 tasks, running every night on different times without overlapping. It works for some days - usually 2-3 up to 10 (it's really random), then it stops running the tasks. When I look at the history, I see that the tasks completed successfully. In the UI, the column "Next Run Time" stays empty. The tasks are set to run on background; the account for running them is a domain one - it is valid and enabled. When I check with Process Explorer, there are no left-over processes associated with my tasks. I am completely baffled at what's going on.

  • ICQ offline messages (do not show up)

    - by Nils Riedemann
    Hi there, I have a weird problem with offline messages: I use Adium on 2 Macs (home and office) and Beejive (iPhone) for connecting to ICQ and other protocols. When someone sends me an offline messages I expect them to show up the next time I login with any of my 3 devices. But thats not the case. Recently some show up at the office, some at home and some on my iPhone – couldnt figure out any logic behind it, seems rather random. I thought for a while that it depends on the last device i have been logged in with. But thats not the case either. A friend can send me offline Messages during the weekend, i can login with my Mac at home or iPhone, yet in some cases it only shows up when logging in from office. Weird. It really freaks me out – and no, i can't make 'em go to jabber or the like. Anyone experiencing a similar problem?

  • Ubuntu 9.10 X Stuck in restart loop - I think...

    - by widgisoft
    Trying out Ubuntu, installation went fine - upgraded to the proprietary nVidia drivers but on restart I get a login prompt and the screen is flashing really fast almost as if Xserver is trying to start and failing, I can type when the screen isn't in a "flash" as it were and it's so fast and random it's hard to even type a login name without it missing some characters - this makes typing a password (i.e. not being able to see which characters made it or not) very hard. I can log back into the live cd and alter my settings - but I can't even find out how to stop X stop starting on boot; Looks like they've moved everything around :-p I'd like to: Stop X from crashing and going insane (if it is actually Xserver) Know how to stop X from starting on bootup, Looks like interactive boot is also off by default now Update: A temporary work around seems to be enabling ssh and just connecting to the box over the network - ssh seems to work fine :-p Cheers, Chris

  • Managing BES Software Configurations

    - by DaveJohnston
    Hi, I am having problems with OTA deployment of a bespoke application that we have written. I have read loads of threads elsewhere and I have got mixed help, but for my particular case none of it has really helped. So I thought I would explain my exact situation and try and get some help here. I am running BES version 4.1.5 (Bundle 79) for Microsoft Exchange. The application we have written is split into 5 modules, which we control, and another 4 modules which are 3rd party libraries that we require. So for our modules the version numbers are regularly changing but for the others they are pretty much always going to remain the same. We have an alx file set up that identifies all of the files required and in fact I am able to create a software configuration and deploy the application with no problems. What I am trying to do however is maintain multiple versions of our application on the BES and be able to select which version I want to deploy to each user. I have tried this a number of ways (as I said I have read lots of other threads with solutions to this problem) but each seems to come with its own problem. First of all I tried just creating different configurations for each version of the application, but because they each had the same application ID the BES informed me that I couldn't do this. I read somewhere that the solution was to create a second shared folder (e.g. \Program Files\Common Files\RIM) and add the apploader stuff and the new version of the app to this folder. I could then create a second software configuration that would have the same application ID. The result of this seemed promising to start with. When I changed the config that was assigned to a user the new version was pushed out fine. But afterwards the BES reported that the device state was invalid, which meant I couldn't push anything else until I reactivated the device. I guess this is because the first config was never set to disallowed so the old version wasn't removed and the device essentially reported that it had multiple versions of the same application installed. The next suggestion I got was to change the application ID for each version, e.g. to include the version number. This meant that each version of the application could be included in a single configuration and I could set one to disallowed and the other to required. Initially this worked and the first version was deployed. But when I switched (i.e. the old version became disallowed and the new version required) the BES reported upgrade required and removed the old version. The device restarts and the old version is gone but the new version is not pushed out. I checked the BES and it still said Upgrade Required. I checked the log files and found: [40000] (11/12 09:50:27.397):{0xEB8} {[email protected], PIN=1234, UserId=2}SCS::PollDBQueueNewRequests - Queuing POLL_FOR_MISSING_APPS request [40000] (11/12 09:50:28.241):{0xE9C} RequestHandler::PollForMissingApps: Starting Poll For Missing Apps.

(You will notice I have removed actual names and email addresses etc for privacy reasons. But one question: where does the name of the module group come from? In my case it is close to the application ID but doesn't include the version number that I added at the end in order to get it to work. Is that information embedded in a COD file or something??) So it is reporting a duplicate module group on the device? What does this mean? I checked the device properties (as reported on the BES) and it confirms that the modules with the old version numbers are still present on the device. So the application has been removed but not the modules?? I checked the device and the modules are gone, so it is just the BES reporting that they are still there?? I checked the database and it has the modules in questions in the SyncDeviceMgmt table. If I delete these from the DB the BES changes to report Install Required, and low and behold the new version of the app is pushed out. So at the end of all that, my question is: does anyone have any other suggestions of how to handle upgrading our bespoke application OTA from the BES? Or can anyone point out something I am doing wrong in what I described above that might solve the problems I am having? I guess the question is why does the database maintain that the modules are on the device after they are removed? Thanks for any help you can provide.

  • Hard crash when drawing content for CALayer using quartz

    - by Lukasz
    I am trying to figure out why iOS crash my application in the harsh way (no crash logs, immediate shudown with black screen of death with spinner shown for a while). It happens when I render content for CALayer using Quartz. I suspected the memory issue (happens only when testing on the device), but memory logs, as well as instruments allocation logs looks quite OK. Let me past in the fatal function: - (void)renderTiles{ if (rendering) { //NSLog(@"====== RENDERING TILES SKIP ======="); return; } rendering = YES; CGRect b = tileLayer.bounds; CGSize s = b.size; CGFloat imageScale = [[UIScreen mainScreen] scale]; s.height *= imageScale; s.width *= imageScale; dispatch_async(queue, ^{ NSLog(@""); NSLog(@"====== RENDERING TILES START ======="); NSLog(@"1.

  • What is your IT-department to staff ratio?

    - by Bart Silverstrim
    This is a topic that may be rather political but it related to system administration still...how many people do you have supporting your users in your IT department? We have three people supporting something near 1500 systems and around 2400 people and a recent question was raised about why we have long times to get systems replaced, repaired, work orders fulfilled, etc. along with the system admin duties of maintaining the servers (mail, proxy, filters, VOIP, wireless, backup, etc.) Does anyone have numbers on what the "best practices" average is of support people to employees in an organization? EDIT:...from some of the answers that are appearing I'm starting to feel depressed...

  • this program runs but not correctly:brief decription of what i am trying to do can someone tell me i

    - by user320950
    this is what i have to do: write a program that determines the grade dispersal for 100 students You are to read the exam scores into three arrays, one array for each exam. You must then calculate how many students scored A’s (90 or above), B’s (80 or above), C’s (70 or above), D’s (60 or above), and F’s (less than 60). Do this for each exam and write the distribution to the screen. // basic file operations #include <iostream> #include <fstream> using namespace std; int read_file_in_array(double exam[100][3]); double calculate_total(double exam1[], double exam2[], double exam3[]); // function that calcualates grades to see how many 90,80,70,60 //void display_totals(); double exam[100][3]; int main() { double go,go2,go3; double exam[100][3],exam1[100],exam2[100],exam3[100]; go=read_file_in_array(exam); go2=calculate_total(exam1,exam2,exam3); //go3=display_totals(); cout << go,go2,go3; return 0; } /* int display_totals() { int grade_total; grade_total=calculate_total(exam1,exam2,exam3); return 0; } */ double calculate_total(double exam1[],double exam2[],double exam3[]) { int calc_tot,above90=0, above80=0, above70=0, above60=0,i,j, fail=0; double exam[100][3]; calc_tot=read_file_in_array(exam); for(i=0;i<100;i++) { for (j=0; j<3; j++) { exam1[i]=exam[100][0]; exam2[i]=exam[100][1]; exam3[i]=exam[100][2]; if(exam[i][j] <=90 && exam[i][j] >=100) { above90++; { if(exam[i][j] <=80 && exam[i][j] >=89) { above80++; { if(exam[i][j] <=70 && exam[i][j] >=79) { above70++; { if(exam[i][j] <=60 && exam[i][j] >=69) { above60++; { if(exam[i][j] >=59) { fail++; } } } } } } } } } } } return 0; } int read_file_in_array(double exam[100][3]) { ifstream infile; int exam1[100]; int exam2[100]; int exam3[100]; infile.open("grades.txt");// file containing numbers in 3 columns if(infile.fail()) // checks to see if file opended { cout << "error" << endl; } int num, i=0,j=0; while(!infile.eof()) // reads file to end of line { for(i=0;i<100;i++) // array numbers less than 100 { for(j=0;j<3;j++) // while reading get 1st array or element infile >> exam[i][j]; infile >> exam[i][j]; infile >> exam[i][j]; cout << exam[i][j] << endl; { if (!

  • How can I scrape specific data from a website

    - by Stoney
    I'm trying to scrape data from a website for research. The urls are nicely organized in an example.com/x format, with x as an ascending number and all of the pages are structured in the same way. I just need to grab certain headings and a few numbers which are always in the same locations. I'll then need to get this data into structured form for analysis in Excel. I have used wget before to download pages, but I can't figure out how to grab specific lines of text. Excel has a feature to grab data from the web (Data-From Web) but from what I can see it only allows me to download tables. Unfortunately, the data I need is not in tables.

  • HP LaserJet Pro 400 Color M451dn Phantom Print Jobs

    - by francisswest
    Scenario: Multiple printers hooked up to a printer server (2008r2) including this HP LaserJet Pro 400 Color M451dn. All machines that are using the printer are based on Windows 7 Enterprise x64. Problem: Every couple of days the users who frequent this printer let me know that a few dozen pages with random characters down one side of the paper print out. This happens usually during the evening when no one is around to send print jobs to it. What I have done: Provided the below screen shot of the printer log with what I assume is the print jobs in question. I have looked into the printer driver compatibility and found no issues. Question: Is there a known issue with this printer or similar printers, and is there a solution that people are familiar with when they see multiple pages of gibberish printing out?

  • Is there an apache module to slow down site scans?

    - by florin
    I am administering a few web servers. Each night, random hosts from the Internet are probing them for various vulnerabilities in php, phpadmin, horde, mysqladmin, etc. Is there a way (apache plugin?) to slow down the rate of attack? For SSH, I have a rate limiting rule on the firewall, which does not allow more than three connections per minute. But I don't want to rate limit all HTTP access, only the access that returns 404s. Is there such an apache module?

  • OOM-Killer called every now and then..

    - by SpyrosP
    Hello there, i have a dedicated server where i've installed apache2, as well as Rails Passenger. Although i have 2GBs of RAM and most times about 1,5GB is free, there are some random times when i lose ssh and generic connectivity because oom-killer is killing processes. I suppose there is a memory leak but i cannot find out where it comes from. oom-killer kills apache2, mysql, passenger, whatever. Yesterday, i did a "cat syslog | grep -c oom-killer" and got 57 occurences ! It seems that something seriously destroys the memory. Once i reboot, everything comes back to normal. I suspect that it can be related to Passenger, but i'm still trying to figure it out. Can you think of anything else, or do you have anything to suggest that will make the leak identification procedure easier ? (i was even thinking of writing a bash script, to be run with cron for like every 5 minutes).

  • losetup does not decrypt device in Ubuntu 11.4 as before

    - by Kay
    I had an external volume mounted using losetup for about two years. It was created using Ubuntu 9.4 and I used the same Ubuntu installation throughout all dist upgrades. Now as I bought a new laptop I set up a fresh Ubuntu 11.4 installation on it. Problem is: losetup -e twofish /dev/loop0 /dev/sdb2 does not decrypt the volume anymore. The data in /dev/loop0 contains apparently random data. I am sure I entered the correct password. I modprobe'd cryptoloop and twofish. My question is: Has Canonical done some obscure changes to losetup like adding a salt? Does losetup depend on configuration files I did not know about? How can I decrypt the volume on my now laptop?

  • Increasing speed of python code

    - by Curious2learn
    Hi, I have some python code that has many classes. I used cProfile to find that the total time to run the program is 68 seconds. I found that the following function in a class called Buyers takes about 60 seconds of those 68 seconds. I have to run the program about 100 times, so any increase in speed will help. Can you suggest ways to increase the speed by modifying the code? If you need more information that will help, please let me know. def qtyDemanded(self, timePd, priceVector): '''Returns quantity demanded in period timePd. In addition, also updates the list of customers and non-customers. Inputs: timePd and priceVector Output: count of people for whom priceVector[-1] < utility ''' ## Initialize count of customers to zero ## Set self.customers and self.nonCustomers to empty lists price = priceVector[-1] count = 0 self.customers = [] self.nonCustomers = [] for person in self.people: if person.utility >= price: person.customer = 1 self.customers.append(person) else: person.customer = 0 self.nonCustomers.append(person) return len(self.customers) self.people is a list of person objects. Each person has customer and utility as its attributes. EDIT - responsed added ------------------------------------- Thanks so much for the suggestions. Here is the response to some questions and suggestions people have kindly made. I have not tried them all, but will try others and write back later. (1) @amber - the function is accessed 80,000 times. (2) @gnibbler and others - self.people is a list of Person objects in memory. Not connected to a database. (3) @Hugh Bothwell cumtime taken by the original function - 60.8 s (accessed 80000 times) cumtime taken by the new function with local function aliases as suggested - 56.4 s (accessed 80000 times) (4) @rotoglup and @Martin Thomas I have not tried your solutions yet. I need to check the rest of the code to see the places where I use self.customers before I can make the change of not appending the customers to self.customers list. But I will try this and write back. (5) @TryPyPy - thanks for your kind offer to check the code. Let me first read a little on the suggestions you have made to see if those will be feasible to use. EDIT 2 Some suggested that since I am flagging the customers and noncustomers in the self.people, I should try without creating separate lists of self.customers and self.noncustomers using append. Instead, I should loop over the self.people to find the number of customers. I tried the following code and timed both functions below f_w_append and f_wo_append. I did find that the latter takes less time, but it is still 96% of the time taken by the former. That is, it is a very small increase in the speed. @TryPyPy - The following piece of code is complete enough to check the bottleneck function, in case your offer is still there to check it with other compilers. Thanks again to everyone who replied. import numpy class person(object): def __init__(self, util): self.utility = util self.customer = 0 class population(object): def __init__(self, numpeople): self.people = [] self.cus = [] self.noncus = [] numpy.random.seed(1) utils = numpy.random.uniform(0, 300, numpeople) for u in utils: per = person(u) self.people.append(per) popn = population(300) def f_w_append(): '''Function with append''' P = 75 cus = [] noncus = [] for per in popn.people: if per.utility >= P: per.customer = 1 cus.append(per) else: per.customer = 0 noncus.append(per) return len(cus) def f_wo_append(): '''Function without append''' P = 75 for per in popn.people: if per.utility >= P: per.customer = 1 else: per.customer = 0 numcustomers = 0 for per in popn.people: if per.customer == 1: numcustomers += 1 return numcustomers

  • Debian Harddrive Fdisk - Same ID's and changing letters

    - by James Willson
    I am trying to create and install a debain NAS and ive been having a hard time because I am new to all of this. I used ntfs-3g in order to automount my 4 NTFS drives. I also have a partitioned harddrive which is for the OS. When I was working on it and I ran this command I got this: fdisk -l /dev/sdae1 fdisk -l | grep NTFS /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 The weird thing is, all of the NTFS harddrives listed had an ID of 7. The next time I boot up my machine, I get an error about mounting /dev/sda1 and I run this command, and get the following results: fdisk -l | grep NTFS /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 I havent plugged in any drives, so whats going on? How to I make sure that my drives are mounted with the same sdXX name every time, and is the reason for this because they dont have unique ID numbers, if so, how do I solve this?
