  • How can I copy this quote from PDF?

    - by isme
    I'm reading a PDF copy of Jerome H. Friedman's paper "Data Mining and Statistics: What's the Connection?" using Google Chrome and the Adobe Reader plugin. It contains an amusing quote that I want to copy and paste to my blog. I used the mouse to select the text of the quote and pressed CTRL + C to copy the text. The document looks like this: When I paste the text into Notepad, Stack Overflow, or anywhere else, the product is Wingdings-like gibberish: ????????????????????????|?????????|????? ?????|??????????????????????????????????????????????????|?????????????? ??????????????P????? ?????????????????????P?|?????????|?????????????????????????????????????????????????????? ????????????Þ?????????????????????????????????|???|??????????????????????????? The text should instead look like this: A difference between statisticians and computer scientists in this field seems to be that when a statistician has an idea he or she writes a paper; a computer scientist starts a company. I had to type that text out manually. This is feasible for such a small quote, but how do I actually copy what I see? Is it something unusual about the PDF, the browser, the plugin, or some combiniation of the three?

  • VPN Setup: Mac OS X and SonicWall

    - by noloader
    I'm trying to get VPN access up and running. The company has a SonicWall firewall/concentrator and I'm working on a Mac. I'm not sure of the SonicWall's hardware or software level. My MacBook Pro is OS X 10.8, x64, fully patched. The Mac Networking applet claims the remote server is not responding. The connection attempt subsequently fails: This is utter bullshit, as a Wireshark trace shows the Protected Mode negotiation, and then the fallback to Quick Mode: I have two questions (1) does Mac OS X VPN work in real life? (2) Are there any trustworthy (non-Apple) tools to test and diagnose the connection problem (Wireshark is a cannon and I have to interpret the results)? And a third question (off topic): what is broken in Cupertino such that so much broken software gets past their QA department? EDIT (12/14/2012): The network guy sent me "VPN Configuration Guide" (Equinox document SonicOS_Standard-6-EN). It seems an IPSec VPN now requires a Firewall Unique Identifier. Just to be sure, I revisited RFC 2409, where Main Mode, Aggressive Mode, and Quick Mode are discussed. I cannot find a reference to Firewall Unique Identifier. I think I am screwed here: I am trying to connect to a broken (non-standard) firewall, with a broken Mac OS X client. Fortunately, I can purchase VPN Tracker Personal (a {SonicWall|Equinox}-authored client) for $129US from Equinox. So much for standards....

  • Getting rid of your server in a small business environment

    - by andygeers
    In a small business environment, is it still necessary to have a central server? Speaking for my own company (a small charity with about 12 employees) we use our server (Windows Server 2003) for the following: Email via Microsoft Exchange Central storage Acting as a print server User authentication / Active Directory There are significant costs associated with running a server like this: Electricity, first for the server itself then for the air conditioning required (this thing pumps out a lot of heat) Noise (of which there is a lot) IT support bills (both Windows Server and Exchange are pretty complicated, and there are many ways they can go wrong) I've found ways to replace many of these functions with cheaper (better?) alternatives: Google Apps / GMail is a clear win for us: we have so many spam related problems it's not even funny, and Outlook is dog slow on our aging computers You can buy networked storage devices with built in print servers, such as the Netgear ReadyNAS™ RND4210 that would allow us to store/share all of our documents, and allow us to access printers over the network The only thing that I can't figure out how to do away with is the authentication side of things - it seems to me that if we got rid of our server, you'd essentially have a bunch of independent PCs that had no shared pool of user accounts / no central administrator. Is that right? Does that matter? Am I missing any other good reasons to keep a central server? Does anybody know of any good, cost-effective ways of achieving the same end but without the expensive central server?

  • Why do hosts prefer Linux to Windows Server?

    - by iconiK
    So far I see a HUGE majority of hosts provide only Linux shared hosting, providing Windows only to VPS (or even to only dedicated servers). Why is it so? While Windows is a lot more expensive than Linux (though it depends on a lot of factors, not just initial and support license cost), it also provides ASP.NET, IIS and of course, Microsoft SQL Server. I know in the past it might have been because of cPanel being Linux only but now they have a Windows version. But still, why is Linux predominantly used on shared hosting? PHP works on both systems. IIS can be (and probably is) faster. MySQL runs on both systems as well. cPanel has a Windows version. Python, Perl, Ruby, all run on Windows as well. You even have MS SQL Server Express, which I find more superior than MySQL in both speed and features. Access is there for low usage requirements, as is SQLite (which is so great for quick small stuff). And with PowerShell you have a good alternative to the Unix shell. EDIT: I am looking for common reasons, I realize each hosting company (and/or it's clients) may have different needs. This becomes very important when you get to VPS or Cloud which give you a full operating system to use.

  • Sudoers file allow sudo on specific file for active directory group

    - by tubaguy50035
    I have active directory sign in working on an Ubuntu 12.04 box. When the user signs in, I have a script that runs that needs sudo permission (since it modifies the samba config file). How would I specify this in my sudoer's file? I've tried: %DOMAIN\\AD+Programmers ALL=NOPASSWD: /usr/local/bin/createSambaShare.php I've found various resources on the internet stating that this is how it would be done, but I'm not sure that I have the first part right. What are they using as the DOMAIN? The workgroup or the realm? I use Samba + winbind for active directory integration. Here's my smb.conf: [global] security = ads netbios name = hostname realm = COMPANYNAME.COM password server = passwordserver workgroup = COMPANYNAME idmap uid = 1000-10000 idmap gid = 1000-10000 winbind separator = + winbind enum users = no winbind enum groups = no winbind use default domain = yes template homedir = /home/%D/%U template shell = /bin/bash client use spnego = yes domain master = no EDIT: The users that should have access to run that script are all part of the Programmers group which has an Active Directory Domain Services Folder of Company.com/Staff/Security Groups (not sure if that matters or not).

  • HP Power Manager SMTP setup doesn't have space for username & password

    - by Martha
    Is there some way to configure HP Power Manager to not assume that there's an email server running locally? We recently acquired an HP T1500 G3 UPS, which we're trying to control using HP Power Manager 4.2. The main reason we wanted to get this particular UPS is because it says it's capable of sending notifications (of the "Yo, the power's out, you may want to look into it" type) via email, as opposed to SNMP. Turns out, that's not entirely true. The server is running Windows Server 2003. It is not running an email server of any sort - we do that via two different providers. Outlook email is provided by Verizon, and our SMTP email service is provided by a small local company. When we use CDO to send auto-generated notification emails, we have to provide the SMTP server name, port, username, and password. The HP Power Manager interface only allows us to enter the server name and the username. Thus, not surprisingly, the emails never go anywhere. Help?

  • About to go live: virtual dedicated server or cloud?

    - by morpheous
    I am about to launch my startup company, and we will be going live in a few weeks time. We have really tight budgetary constraints, since we are bootstrapping - and would prefer not to raise external capital. I cant use shared hosting because I need more control of the server machine (for technical reasons - e.g. using proprietary extensions to PHP, Apache and in the database layer as well) - but want to control costs and dont want to go fully private server route, until we have determined the market size etc. So the only real alternatives AFAIK is between virtual server and the cloud. At the moment, cloud services seem a bit "vague" to me. My understanding is that they allow an entity to outsource its IT infrastructure, which in my mind (at least), is indistinguishable from what a hosting provider provides (at least from a functional point of view) - I would like to seek some clarification on exactly what the difference between the two is. Back to my original question, my requirements are: IT infrastructure that can scale with growth Ability to have control of the machine (for e.g. to install our internally developed libraries etc) Backup software that is flexible and comprehensive enough (yet simple to use), that allows a (secured) backup strategy to be implemented. On this issue, I have always wondered where the actual backed up data was stored (since the physical machines are remote, and one cant get access to any actual tapes etc backed onto). I would also like some advice and recommendations in this area. Regarding data size, I am expecting the dataset to be increasing by a few megabytes of data (originally, say 10Mb, in about a years time, possibly 50Mb) every day. As an aside, I have decided to deploy on a Debian server (most of my additional libraries etc were compiled and built on a Debian machine). Mindful of all of the above, I would like some advice (and reason) as to which route to take. I would also like some advice on which backup software to use, from people who have walked a similar path.

  • E-mail duplication problem

    - by Gavin Osborn
    I have taken out a hosting agreement with a well respected hosting provider for a couple of internet facing servers. We have deployed several applications to these servers which send various e-mails back to us for reporting purposes. Context: Each server runs Windows Server 2003 R2 with the IIS 6.0 SMTP service installed. Each application is configured to use the local instance of IIS to send e-mails. The external IP address of each server is mapped to a particular domain eg: server1.mydomain.com server2.mydomain.com These e-mails are sent from a company domain name and not the domain name of the hosted servers (eg: [email protected]) Symptoms: A small number (<1%) of e-mails sent from these applications appear to be duplicated. These are exact duplicate in terms of both content and message headers. The Fix: I contacted my hosting provider and they told me this was a common problem & instructed me to: Change the HELO response of your mail server service to a FQDN (server1.mydomain.com && server2.mydomain.com) Create a DNS A record that resolves the FQDN of your mail server to the primary IP address of your sending mail server. Create a PTR record that resolves your primary IP address back to your mail server's FQDN In the sending domain's (mycompanydomain.com) DNS zone file, add the appropriate SPF record for your hosted servers. eg: v=spf1 a mx include:mydomain -all The Problem Continues: I made all of the changes as prescribed above, I was a little hesitant because these steps seemed to suggest they were more for stopping your messages getting blocked than they were for stopping them from being duplicated - but I am certainly no expert in these matters. It has been 5 days since I applied this fix and the problem still persists. I am certain that these problems are not a bug in the software because they are 4 different applications installed on 2 different servers, all of whom are exhibiting this strange behaviour. This behaviour has also not been seen in our UAT environment. Were my hosts correct to suggest this fix? If not, does anyone know what could be the cause of this problem? Many Thanks

  • How to bypass vpn talking to VMWare Guest?

    - by marc esher
    Greetings. Network/VPN n00b question here. I'm running VMWare Workstation with a Guest Windows 2003 Server. It has SQL Server 2000 installed. The sole purpose for this Guest is to house SQL Server... it needn't have internet access or access to any other resources on the network other than the host. When launch Check Point VPN software, the host routes through the company network before it connects to the guest ... i.e. it's no longer a direct connection. I assume this is just how things are supposed to work. However, what's happening is that the connection between my host and the SQL Server instance on the guest intermittently drops. It's not consistent, and some databases on the server will be responsive while others aren't. It appears that the databases with the most traffic on the guest (the ones I'm hitting with load tests) are the ones that become intermittently unresponsive. This problem only manifests when VPN is on; when it's off, I can pound away on this database with no troubles. Thanks for any advice!

  • Overriding HOMEDRIVE and HOMEPATH as a Windows 7 user

    - by MikeC
    My employer has an Active Directory group policy which sets my Windows 7 laptop HOMEDRIVE to "M:" (a mapped network drive) and my HOMEPATH to "\". Since I have read-only permissions for the root of that shared drive, I cannot create files or directories in my windows home directory. My attempts to work with the IT department have been unsuccessful. Is there a way for me to globally change these envars at boot or login time? I need for all applications to use alternate values (such as "C:" and "\Users\myname"). I have some installed utilities (like gvim and others) that store preference files in the user's home directory. IMPORTANT: Changing these envars under "System Properties Environment Variables" does not work. I have tried setting these as both User and System Variables (including a reboot). TypingSET HOMEin a DOS window clearly shows that my settings are ignored. Also, using "Start in" in a Windows shortcut will also not solve this, as I need things like Explorer context menu items (like "Edit with Vim") to operate correctly. I do have admin rights on this company laptop, but I am not a Win7 guru. Back in the day, a boot script would have solved this in a minute. Is it even possible today? Thanks.

  • Windows 7 comments field missing when browsing network

    - by Toymangenie
    I have just purchased three Windows 7 Professional Dell 64-bit PCs for testing prior to upgrading our company’s 120+ PCs from Windows XP Professional. The setup is a standard domain with a Windows Server 2003 32-bit server. We name each PC XP1 to XP150 so that when users join or leave, I don’t have to rename the PC. We use the Description field to allocate the user’s name to each PC. We also have a share set up on each PC using the user’s name. When I browse the network using Windows Explorer in XP, I get a useful display. The left pane showing the PC number and the right pane showing NAME and COMMENTS So, for example I would see: XP01 Fred Bloggs (Each PC on a new row.) The right pane is my main tool for administering the network. I can easily see the PC number and the name of the user. However, in Windows 7, this seems to have been thrown out of the window and replaced with fields that I do not need and in my case always display the same info. "Name", "Category", "Workgroup", "Network Location" In my case the Name column gives the PC number (XP10) etc and all three other columns display identical useless information. So I can’t see who is using XP10. When I am in “help desk” mode, I would naturally ask the user’s name and use my remote desktop client to view their screen. The user isn’t aware of their PC name, so I am finding it impossible to match the user name with a PC number. Any ideas how to overcome this "by design" change to Windows 7?

  • UPS power requirements for server

    - by captainentropy
    Greetings! So, I just placed an order for a new server. The company recommended that I get a 3000W UPS. (!) As best as I could I calculated the following wattage consumption based on benchmarked data or datasheets provided by the manufacturers of each component: number watts **total watts** MoBo 1 240 240 CPUs (E5540) 2 80 160 RAID cards (3ware) 2 18 36 RAM (6x4GB) 6 3 18 DVD drive 1 7 7 floppy 1 2 2 RE4 drives 8 7 56 WD20 drives 8 6 48 Intel X25 SSD 2 0.15 0.3 total = 567 So that is for the PSU requirements only. The PSUs in the machine are a 720W for the master node and 800W each for two subsystems. That's a total of 2320W that can be delivered by these PSUs. But that is 4X the amount being consumed, at most, by the components. I didn't count case fans or the eSATA card (3W maybe?) or what the PSUs themselves require but assuming I double or triple my calculations I'm not even remotely close to the 3000W UPS I was suggested to get. They run at least $1100. I could get a 2000W for about $750 or a 1500W for $450 and still be well over my estimated power need. I don't think I need a whole lot of run time in the case of a power outage, maybe 20 minutes max, enough time to shutdown if the power doesn't come on within 5-10 minutes. Any thoughts? Am I off on my calculations? Did I overlook something major? If so what are your suggestions for a UPS? Thanks!

  • UDP blocked by Windows XP Firewall when sending to local machine

    - by user36367
    I work for a software development company but the issue doesn't seem to be programming-related. Here is my setup: Windows XP Professional with Service Pack 3, all updated Program that sends UDP datagrams Program that receives UDP datagrams Windows Firewall set to allow inbound UDP datagrams on a specific port (Scope: Subnet) If I send a UDP datagram on any port to other, similar machines, it goes through. If I send the UDP datagram to the same computer running the program that sends (whether using broadcast, localhost IP or the specific IP of the machine), the receiver program gets nothing. I've traced the problem down to the Windows XP Firewall, as Windows 7 does not have this problem (and I do not wish to sully my hands with Vista). If the exception I create for that UDP port in the WinXP firewall is set for a Scope of Subnet the datagram is blocked, but if I set it to All Computers or specifically enter my network settings (192.168.2.161 or 192.168.2.0/255.255.255.0) it works fine. Using different UDP ports makes no difference. I've tried different programs to reproduce this problem (ServerTalk to send and either IP Port Spy or PortPeeker to receive) to make sure it's not our code that's the issue, and those programs' datagrams were blocked as well. Also, that computer only has one network interface, so there are no additional network weirdness. I receive my IP from a DHCP server, so this is a straightforward setup. Given that it doesn't happen in Windows 7 I must assume it's a defect in the Windows XP Firewall, but I'd think someone else would have encountered this problem before. Has anyone encountered anything like this? Any ideas?

  • Diagnosing Logon Audit Failure event log entries

    - by Scott Mitchell
    I help a client manage a website that is run on a dedicated web server at a hosting company. Recently, we noticed that over the last two weeks there have been tens of thousands of Audit Failure entries in the Security Event Log with Task Category of Logon - these have been coming in about every two seconds, but interesting stopped altogether as of two days ago. In general, the event description looks like the following: An account failed to log on. Subject: Security ID: SYSTEM Account Name: ...The Hosting Account... Account Domain: ...The Domain... Logon ID: 0x3e7 Logon Type: 10 Account For Which Logon Failed: Security ID: NULL SID Account Name: david Account Domain: ...The Domain... Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc0000064 Process Information: Caller Process ID: 0x154c Caller Process Name: C:\Windows\System32\winlogon.exe Network Information: Workstation Name: ...The Domain... Source Network Address: 173.231.24.18 Source Port: 1605 The value in the Account Name field differs. Above you see "david" but there are ones with "john", "console", "sys", and even ones like "support83423" and whatnot. The Logon Type field indicates that the logon attempt was a remote interactive attempt via Terminal Services or Remote Desktop. My presumption is that these are some brute force attacks attempting to guess username/password combinations in order to log into our dedicated server. Are these presumptions correct? Are these types of attacks pretty common? Is there a way to help stop these types of attacks? We need to be able to access the desktop via Remote Desktop so simply turning off that service is not feasible. Thanks

  • How can I safely close this window and forever avoid seeing similar pop-ups from Mackeeper Zeobit's malware and spyware?

    - by Michael Prescott
    The attached image shows a window that just popped up and the only button available is the OK button. I could Force quit Safari, but I've got several sites open right now and don't want to try and find my place again. Besides, I've seen similar hacks in the past and I'd like to learn how to handle them in a way better than just a brute force-quit. I've never heard of MacKeeper or Zeobit, so I opened Firefox and did a few searches while Safari is obviously still stuck, waiting for me to click the sneaky OK button in the dialog window. Anyhow, at least the first few pages of most search results contain lots of blabbering from questionable witnesses about how MacKeeper saved them from some malware or spyware. However, any company that is hacking the browser to maliciously install their product is itself the criminal and not providing a true security application. So, there are three questions here: How can I close this window? Can I do something to Safari to avoid these hacks in the future? (Just curious) Is MacKeeper or Zeobit somehow loading the search results so that no information about their application being malware or spyware is listed (I can't be the only person in the world that is offended by their tactics, even though it appears I am)?

  • Debian x86_64 + Nginx + PHP5-FPM optimization

    - by Olal'a
    I used to have a VPS (512MB) from Linode and I was running nginx + php5-fpm (which comes with php5.3.3) on Debian Lenny (i686). The total memory usage was about 90-100MB. Now I have another VPS (different hosting company) and I also run nginx + php5-fpm on Debian Lenny (x86_64). The system is 64-bit, so the memory usage is higher now, about 210-230MB, which I think is too much. Here is my php5-fpm.conf: pm = dynamic pm.max_children = 5 pm.start_servers = 2 pm.min_spare_servers = 2 pm.max_spare_servers = 5 pm.max_requests = 300 That's what top command tells me: top - 15:36:58 up 3 days, 16:05, 1 user, load average: 0.00, 0.00, 0.00 Tasks: 209 total, 1 running, 208 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.0%sy, 0.0%ni, 99.9%id, 0.1%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 532288k total, 469628k used, 62660k free, 28760k buffers Swap: 1048568k total, 408k used, 1048160k free, 210060k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 22806 www-data 20 0 178m 67m 31m S 1 13.1 0:05.02 php5-fpm 8980 mysql 20 0 241m 55m 7384 S 0 10.6 2:42.42 mysqld 22807 www-data 20 0 162m 43m 22m S 0 8.3 0:04.84 php5-fpm 22808 www-data 20 0 160m 41m 23m S 0 8.0 0:04.68 php5-fpm 25102 www-data 20 0 151m 30m 21m S 0 5.9 0:00.80 php5-fpm 10849 root 20 0 44100 8352 1808 S 0 1.6 0:03.16 munin-node 22805 root 20 0 145m 4712 1472 S 0 0.9 0:00.16 php5-fpm 21859 root 20 0 66168 3248 2540 S 1 0.6 0:00.02 sshd 21863 root 20 0 66028 3188 2548 S 0 0.6 0:00.06 sshd 3956 www-data 20 0 31756 3052 928 S 0 0.6 0:06.42 nginx 3954 www-data 20 0 31712 3036 928 S 0 0.6 0:06.74 nginx 3951 www-data 20 0 31712 3008 928 S 0 0.6 0:06.42 nginx 3957 www-data 20 0 31688 2992 928 S 0 0.6 0:06.56 nginx 3950 www-data 20 0 31676 2980 928 S 0 0.6 0:06.72 nginx 3955 www-data 20 0 31552 2896 928 S 0 0.5 0:06.56 nginx 3953 www-data 20 0 31552 2888 928 S 0 0.5 0:06.42 nginx 3952 www-data 20 0 31544 2880 928 S 0 0.5 0:06.60 nginx So, the question is there any way to use less memory?

  • DPMS does not work: the monitor is not switched off

  • What is the main reason of adsl modem/routers dying ?

    - by ldigas
    The other day my home adsl modem/router (dwg 684t in this case) died. A guy from the telecom company came, brought another so no problem in day to day operation, but he also left this one. Now, I'm interested ... it didn't fall, it wasn't electrocuted ... but it just doesn't work. What could be the problem ? Can they be fixed ? Is it worth it (in which case I would have two which is always nice) ... What are the usual problems that occur with them ? In this case, I can connect to the router, I can see its settings, I just can't connect to the internet. With the new one everything works. Weird. Edit: Additional question: Can those things be fixed ? I mean, is it worth giving it to a local tinker for him to experiment on it ? I'm not looking for a definite opinion, just your personal advice ... (although in the end I think I'm gonna archive it in the "cylinder register")

  • Difference between CurrentClockSpeed and MaxClockSpeed

    - by Ben
    Rationale this belongs on ServerFault rather than StackOverflow - I already have my program which gets the value, I am querying the value returned and what it means. I have an in-house program which audits our company PCs, and one of the things it checks is the speed of the processor. To do this, it queries the Win32_Processor WMI class and gets the value of CurrentClockSpeed. We were playing with the data today and found an anomaly with some of the speeds being reported incorrectly (for example, CurrentClockSpeed said 1.0GHz, whereas the CPU name said Intel(R) Core(TM)2 CPU T5600 @ 1.83GHz [Confirmed it is in fact 1.83GHz]). I did a bit of digging on the internet and found this blog post which might explain what is going on. My initial thought was that I could change the program to instead get the value for MaxClockSpeed instead of CurrentClockSpeed, but Microsoft's documentation doesn't clearly define what this will return. What I mean by that is will this return a value which is its actual maximum speed (say if it were overclocked) but which it would not normally be running at, or would it return what I expect, which is its maximum speed under normal (not overclocked) conditions?

  • DDoS nulling to some ips and other options?

    - by Prix
    I am looking for some information in regards DDoS in the follow scenario: I have a server that is behind a Cisco Guard and it will be DDoS'ed, I only care about a set list of IPS that by not means are the attackers. Is it possible to null all other ips but this list to actually get any response to my server or in the long run no matter what I do if they have enough DDoS power I will just go down like a flie ? Is there any recommended company out there that can actually cope with a DDoS ? My server will mainly run several clients that will get connected to a external server and all it needs access to is my local MySQL the the private network so I can access it. There will be no other services runnings such as web or ftp etc at least not to the external ips of the server if i ever have to have any of these service they will be on the private network. The MySQL will be available externally only to 1 safe ip not known by anyone but me and internally at localhost + private network. Are there any solutions ?

  • Internet Explorer will not open

    - by KCotreau
    I recently migrated a company to a Microsoft domain environment, logged the users in under their new domain accounts, and then copied the old profiles to the new profile. I am not sure if that is related since they did not complain about it right away and it may have been a subsequent patch or something, but I have two XP computers that will not open IE8. You click on it, and it nothing graphically happens at all, but you can see a process in task manager. If you click many times, you get multiple instances. It will appear often TWICE per click. It still works in the old profile, so it is specific to the profile, and I would like to fix it rather than blow it away. Here is what I have done without success: Tried opening without add-ons (the one in System Tools) Reinstalled IE8 Ran SFC /SCANNOW I found a script that was supposed to repair any registry entries, and ran it. I tried exporting the whole HKCU\Software\Microsoft\Internet Explorer key and deleting it, hoping that when I restarted it, it would recreate it...No joy. I restored it. Any ideas?

  • Self-connecting printers

    - by Martin Cerny
    Hello, I work as an administrator in a small company using XP Professional on all computers and two servers with Win 2003 Server. Recently a very unusual problam occured one of the computers keeps connecting to all the printers on the network it doesn't matter if it's an administrator or Domain User as soon as somebody logs in the commputer connects all the printers. The printers are either installed on local computers or on the server and shared. There is no log-on script connecting the printers, I install them manualy and none of the other computers shows such behaviour. We have a printer which is installed on two computers and both of them share it (I'm moving it to Server from a small PC which shared it up to now, but some computers still use the old connection), meaning this specific computer connects to one of the printer two times and it can't use either of the connections. How to prevent this self-connecting to all printers (none of the other computers has this problem). If I delte them from the "Printers" folder everything works fine untill I reconnect and the Folder is once again full of all the printers we have. I solved the smaller problem, computer is now capable of printing on all of the printers (it seems there have been some registry issues), after cleaning the registry and reinstalling the printer it seems to work just fine. But the second thing prevails, the computer connects to all the printers in the network (when I remove one/multiple it is reconnected right after the next log-in by any user).

  • AWS own email domain and some generic questions

    - by John Brunner
    I'm getting started with Amazon Web Services and I have a few question I'm not sure about. As every (company) webpage I want to use an "[email protected]" email adress, but how is that done? I looked up at godaddy.com (for domain registration), the offer me an email adress like I want, but for 3 dollars per month. Is this possible with AWS? Because at AWS you have just a complex domain which is not very userfriendly or serious. Also I want to host my dynamic webpage on the amazon cloud, but I'm not sure if I'm doing that right. I've read many guides, and all I know is that I have to purchase a Elastic Compute Cloud, and a Simple Storage Service... and every guide is working with the basic linux package, why not Windows? Is it more expensive? I just want to host a mySQL Server for the dynamic webpage, which is reached over a normal domain. And one last question, if I sign up for an AWS account it asks me for an email account. But I found it a little bit unserious to write there my free-webmailer-adress... How is it done the normal way? Thanks in advance! Best regards, john.

  • UDP blocked by Windows XP Firewall when sending to local machine

    - by user36367
    Hi there, I work for a software development company but the issue doesn't seem to be programming-related. Here is my setup: - Windows XP Professional with Service Pack 3, all updated - Program that sends UDP datagrams - Program that receives UDP datagrams - Windows Firewall set to allow inbound UDP datagrams on a specific port (Scope: Subnet) If I send a UDP datagram on any port to other, similar machines, it goes through. If I send the UDP datagram to the same computer running the program that sends (whether using broadcast, localhost IP or the specific IP of the machine), the receiver program gets nothing. I've traced the problem down to the Windows XP Firewall, as Windows 7 does not have this problem (and I do not wish to sully my hands with Vista). If the exception I create for that UDP port in the WinXP firewall is set for a Scope of Subnet the datagram is blocked, but if I set it to All Computers or specifically enter my network settings (192.168.2.161 or 192.168.2.0/255.255.255.0) it works fine. Using different UDP ports makes no difference. I've tried different programs to reproduce this problem (ServerTalk to send and either IP Port Spy or PortPeeker to receive) to make sure it's not our code that's the issue, and those programs' datagrams were blocked as well. Also, that computer only has one network interface, so there are no additional network weirdness. I receive my IP from a DHCP server, so this is a straightforward setup. Given that it doesn't happen in Windows 7 I must assume it's a defect in the Windows XP Firewall, but I'd think someone else would have encountered this problem before. Has anyone encountered anything like this? Any ideas? Thanks in advance!
