• Store system passwords with easy and secure access

  - by CodeShining

  I'm having to handle several VPS/services and I always set passwords to be different and random. What kind of storage do you suggest to keep these passwords safe and let me access them easily? These passwords are used for services like databases, webserver user and so on that run customers' services, so it's really important to keep them in a safe place and strong. I'm actually storing them in a google drive spreadsheet file, describing user, password, role, service. Do you know of better solutions? I'd like to keep them on a remote service to make sure I don't have to make backup copies (in case my hdd would fail somehow). I do work on *nix platforms (so windows specific solutions are not a choice here).

• Exclude localhost from htt_proxy

  - by Chilloutman

  I'm trying to access a server that is running locally on my machine (localhost). I'm using the "wget"-command to download the servers http-response. I've also tried using the "curl"-command to do this, but both (wget and curl) are trying to get through my proxy-server and failing at it: --2010-05-04 09:05:34-- http://localhost:8080/api/getplist ... Proxy request sent, awaiting response... 503 Service Unavailable 2010-05-04 09:05:35 ERROR 503: Service Unavailable. Obviously they shouldn't need to go through the proxy, right? So I disabled the http_proxy: export http_proxy="" And then it worked fine. Disabling the the http_proxy every time or permanently are no options. How can I set it to ignore the proxy settings when accessing "localhost"?

• On Developing Web Services with Global State

  - by user74418

  I'm new to web programming. I'm more experienced and comfortable with client-side code. Recently, I've been dabbling in web programming through Python's Google App Engine. I ran into some difficulty while trying to write some simple apps for the purposes of learning, mainly involving how to maintain some kind of consistent universally-accessible state for the application. I tried to write a simple queueing management system, the kind you would expect to be used in a small clinic, or at a cafeteria. Typically, this is done with hardware. You take a number from a ticketing machine, and when your number is displayed or called you approach the counter for service. Alternatively, you could be given a small pager, which will beep or vibrate when it is your turn to receive service. The former is somewhat better in that you have an idea of how many people are still ahead of you in the queue. In this situation, the global state is the last number in queue, which needs to be updated whenever a request is made to the server. I'm not sure how to best to store and maintain this value in a GAE context. The solution I thought of was to keep the value in the Datastore, attempt to query it during a ticket request, update the value, and then re-store it with put. My problem is that I haven't figured out how to lock the resource so that other requests do not check the value while it is in the middle of being updated. I am concerned that I may end up ticket requests that have the same queue number. Also, the whole solution feels awkward to me. I was wondering if there was a more natural way to accomplish this without having to go through the Datastore. Can anyone with more experience in this domain provide some advice on how to approach the design of the above application?

• How can you import a root certificate to a machine level store in Windows 7

  - by ReluctantAdmin01

  I have a service (Running as local system) that uses an SSL connection. Currently this connection fails because the remote host used a private CA to sign it's certificate. For previous operating systems, I used to use the certificate manager to import the CA cert into the local machine's Trusted Root certificates store. Though I can do the steps with a windows 7 machine, it seems after a reboot that the imported certificates are gone. Here are the steps I'm doing in Windows 7: Open mmc Add Certificates Snap-in for Local Machine Navigate to Third-Party Root Certification Authorities/Certificates Import Root CA Cert. The certificate seems to work fine, using internet explorer or the service to test the SSL connection works, but after a reboot it seems like the change is reverted.

• Apache Bench length failures

  - by Laurens

  I am running Apache Bench against a Ruby on Rails XML-RPC web service that is running on Passenger via mod_passenger. All is fine when I run 1000 requests without concurrency. Bench indicates that all requests successfully complete with no failures. When I run Bench again with a concurrency level of 2, however, requests start to fail due to content length. I am seeing failures rates of 70-80% when using concurrency. This should not happen. The requests I am sending to the web service should always results in the same response. I have used cURL to verify that this is in fact the case. My Rails log is not showing any errors as well so I am curious to see what content Bench actually received and interpreted as a failure. Is there any way to print these failures?

• What protocols will/are ISPs use for IPv6 deployment?

  - by rbeede

  Currently ISPs deal out addresses via DHCP for IPv4 dynamic (single) addresses. What protocol will/are ISPs going to use for IPv6 when they can hand a customer an entire /64 (or /48 if they are nice) block? DHCPv6, RA? For ISPs that support true end-to-end IPv6 will they provide gateway devices (similar to cable modem or true DSL bridges for example) that receive border information for that specific customer? I'm just trying to get an idea of how your common residential service customer will have to configure things in an IPv6 Internet (whenever that comes). Will it be something customers are expected to statically configure on their home wireless router? Today with IPv4 I do it like this: Modem (bridge) passes public IPv4 obtained via DHCPv4 from ISP to second device (wireless router). It in turn has its own DHCPv4 service it provides on the internal lan.

• How to send emails without getting into Spam Act trouble?

  - by Jason

  Lets say I have a database of 60,000 emails. I would like to send them an email notifying them of a new related service (similar to what they've signed up) which adds value to what they already signed up to. I know most of them would welcome it but they did not opt-in for this new related service. I don't want to send out the email invite only to find out I got into some Spam Act trouble. What is a friendly way to reach these targetted audience?

• Restarting Nagios Using PHP

  - by X-Ware

  I am making a tool that is interacting with NAGIOS where some config files should be added so a restart will be needed. What I need to know is how to restart NAGIOS using PHP code since this tool is written in PHP .. when I try to do this using: shell_exec("service nagios restart"); changes do not take place but when I do this manually by the console all changes I did using the PHP script are applied ... after 2 minutes research I found that I am asking linux to execut this command while I am logged in as apache user so I changed the command to: shell_exec('echo "mypass" | sudo -S service nagios restart'); still having the same problem ... new config files are not read until I restart manually any suggestions will be appreciated :)

• CentOS drive mapping? [on hold]

  - by DroidOS

  This is the first time I am posting on this particular StackExchange forum and I hope that I am using the right one for the present question. Briefly, this is what I need to do I am running a web service where users can, amongst other things, upload and store files on the server. What I want to do is to hive off user file storage to a different location so my server (CentOS 64 bit) can concentrate on what it does best - server side scripting and database management. As things stand all user files go into subdirectories in a folder called stash that lies above DOC_ROOT. What I would like to do is Transparently detect all attempts to read/write to stash/sub_folder and get/set file data on a remote server - ideally the latter would be one which replicates files like a CDN so they can be delivered from the closest/fastest location based on where the user's location. Even nicer would be if for all read accesses I could provide a URL that allows the user's browser to fetch the relevant file directly without having to funnel them via my server. I am a relative newbie when it comes to this sort of thing so I hope that I have phrased this question adequately well. From the little searching I done I gathered that WebDAV can be used to map drives to a different location on the web so perhaps that is a starting point. But if that will work I need to Establish how to get WebDAV up and running on my CentOS 64 bit server. Ideally, identify a service that allows this kind of file storage and provides an API I can use in my own scripting. I'd much appreciate any help with this.

• Script to restart BlackBerry services

  - by ICTdesk.net

  Can somebody give me a script advice/example of how to restart services? I have to restart 17 services, but the first 4 services have to be in the right order and after the restart command is given to one of the services, the next one should be started when the previous one is finished. I know I can restart a service by net command, and I can build a delay by for example a ping command that repeats for an x amount of times, but I never know in advance how long it is going to take for a service to restart. Thanks, Kindest regards, Marcel

• DNSCache excesive memory usage Windows Server 2008 R2

  - by MikeT

  We are having an issue with the dnscache service where its memory usage is becoming excessive (~6GB) after a week or two. Restarting the service frees this memory but performing ipconfig /flushdns does not, an ipconfig /displaydns shows aprox 15-20 entries in the cache. We have checked and there appears to be aprox 150 DNS queries per second taking place but I would not expect this to have the effect of causing this memory issue. I have tried to search MSDN for hotfixes or bug reports but I could only find a reference to a memory leak in windows 2003. can anyone suggest how to proceed.

• Local System Account in Windows Server 2008

  - by user31676

  Hi, Have the security persmission or anything else changed for the Local System Account in Windows Server 2008 versus Windows Server 2003? We have a service, that logs on as the Local System Account, that creates folders on the server (same server as the service is installed). It works perfectly when installed on Windows Server 2003 however when installed in Windows Server 2008 the folders do not get created. It appears as if the Local System Account does not have persmission to create the folders. Any insight that anyone can provide is greatly appreciated. Thanks, Scott

• Reasons why ports below 1024 cannot be opened

  - by Sitoplex

  I'm root on a machine I don't know how it was configured. I try to open SSHD on another port than 22 but it does not work. I changed the /etc/ssh/sshd_config file and added a new Port line extra to the Port 22. but it does only work when this second port is a number above 1024. Why is that? How can I find the reason? Infos: I'm restarting it using /etc/init.d/sshd restart as root. "netstat -apn" does not show the port is open by any other service (anyway I tried different ports and only above 1024 work). "telnet localhost port" also shows the service works only when they are above 1024. In iptables all tables are empty. Thanks!

• Using LDAP/Active Directory with PIN based authentication

  - by nishantjr

  We'd like to integrate our service with LDAP, but because of hardware constraints, we're only allow 4 digit user ids and passwords. What would be the best practice for performing such an authetication? We've considered adding User ID and PIN attributes to the LDAP user schema, but we're not sure how happy people would be with modifying their schema to interact with our service. The PIN attribute would have to have the same support that native user passwords have. (hashing and salting etc.) UPDATE Another consideration is how ldap_bind works with this scenario. How do we get it to use an alternate authentication method? Can this even be done without affecting other services that use the same LDAP server?

• Configure a warning when starting an application on Windows

  - by Guy

  I have some software that's licensed to be used on one computer at a time. It connects to a service and retrieves data from that service. If I start the application on a second computer then the first computer's data connection is terminated. There are times when I'll be running the software on Computer1 and it's doing some vital work with its data collection etc. and I'll forget that it's running there and start it on Computer2 causing Computer1's data connection to terminate etc. What I want to do is configure a warning on Computer2 so that each time I start this application it pops up a dialog box and says "Hey, this software might be running on another computer, are you sure you want to start it here?" I'm using Windows 7 on Computer2. Is there anyway for me to accomplish this task?

• direct url to server ip address and port

  - by AM0

  We have a Windows 2012 dedicated server. There’s a custom service running on port xxxxx which accepts connections from our custom built hardware devices over TCP/IP port. As of now we use servername.serverdomain.com:xxxxx to connect to the service and start communication. However, we prefer to use URL instead of server’s name or IP Address. So we got a custom url and set its name servers to point to dedicated server. However, just setting DNS doesn’t seem to be working. Could someone please guide as to how to get it working? UPDATE In short I want www.custom-url.com being forwarded to servername.serverdomain.com:xxxxx. These requests are coming from hardware and not browser.

• Security against IP spoofing [on hold]

  - by user1369975

  I am pursuing a college project, in which I am running three fake services on three ports to protect the main service (say running at port 80). The concept is that if the user is malicious, he'll try to bring the services down and access the fake services. These ports adopt a blocking process of a connection request and record the IP and port of the client. These are logged and aren't granted access on service on port 80. But what to do if the client spoofs his IP? How can I modify my system?

• About output of vga_switcher

  - by zhangjie

  When IGD and DIS both exist in my pc,and I want to disable DIS,so I create a service to switch on and off the DIS.It works.Finally,I decide to add the service command into /etc/rc.local so that DIS will be powered off automatically.Unfortunately,it fails.There's only one command added by myself in the file /etc/rc.local,so I can affirm failure is caused by that added command. Before,I directly added the command "echo OFF /sys/kernel/debug..." into /etc/rc.local,and when I restarted,the system startup fails.So I thought maybe when the command is executed,the DIS hasn't been powered on or ready for work.So conflict occurs!It's just my prediction.Then I added one line command "sleep 1s" before the "echo OFF ...",it works nearly everytime when I start or restart pc,while fails sometimes. The output result of "cat /sys/kernel/debug..." is as following: 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :Pwr:0000:01:00.0 I want know 0000:00:02.0 means what?Time of first power on? If it was really time,I can set the command "sleep 2s" to wait for DIS powered on then "echo OFF ..." Thanks for your advice!

• AR9485 wireless card loses ability to connect after hibernation

  - by DrewDiezel

  This has happened twice now, the first time it happened I just reinstalled Ubuntu. The only things that I've been messing with in terms of networking, have been restarting the network-manager service after I resume from hibernate (because it never works right after resume, but restarting the service fixes that), and changing my mac address with ifconfig wlan0 down && ifconfig wlan0 hw ether 11:22:33:44:55 && ifconfig wlan0 up. using tail | dmesg returns a bunch of attempts to connect, saying something like authenticating ... okay you're connected! now I'm going to just disconnect because I feel like it. (reason=3). Any ideas? If it helps maybe I'll add a picture of the tail|dmesg output later. My wireless drivers are as follows: Atheros AR9485 Wireless Network Adapter Hamachi Network Interface Microsoft Virtual Wifi Miniport Adapter Realtek PCIe GBE Family Controller VirtualBox Host-Only Ethernet Adapter Here is a pastebin of some terminal outputs that could help. Also, the reddit thread has a few answers, for anyone curious. It's located here. It is entirely possible that it's just my school wifi blocking out my laptop, and my home wifi sucks. Wifi does work at places other than my home and school, however my phone can connect to both places. Here is a pastebin of the results of the wireless-info script.

• Nagios state transition and event handler issue

  - by Dattatray

  We are using Nagios to check duplicate processes. define service { use local-service host_name xxx service_description xxx Duplicate Processes check_interval 1 max_check_attempts 1 contact_groups admins event_handler restart-dependent-processes check_command check_procs_duplicate!2!3!2!2!2 } check_procs_duplicate checks if there are any duplicate processes and returns the state - e.g. CRITICAL. The event handler kills the duplicate processes and it's dependent processes and starts one instance of the process and dependent process. At the end of this again Nagios checks if there are any duplicate processes and sets the state accordingly - OK/WARNING/CRITICAL. The event handler takes more time to start the processes and during this time if someone manually starts the process, the state will remain in CRITICAL itself. During the next interval, Nagios will again check for duplicate processes and it will find it again CRITICAL. The event handler will not get executed now, as the previos and current both the states are CRITICAL. Any pointers about how to fix this issue?

• Postfix + LDAP + Recipient Delimiter

  - by Coops

  I'm trying to get my Postfix and LDAP-backend to accept recipent delimiters (aka address extensions). The rest of the mail system is working fine, but when an email is received with an extension (e.g. [email protected]), it tries to look up "coops+test" against the LDAP service and fails. Obviously this is wrong, and it should strip out the "+test" part. In my postfix config the string being passed to the LDAP service is "%s", per an example line below: accounts_query_filter = (&(objectClass=MailAccount)(mail=%s)(accountActive=TRUE)(delete=FALSE)) Is there a postfix variable which represents the email account minus the extension? I've found a similar post here, but no actual solution.

• C# calendar needs Business Logic for real-time reminders? [on hold]

  - by lazfish

  I am not a super experienced C# user, though I have some experience in .Net and VB.Net. Just got this new job and my first assignment is a mission critical part of the business. It is pretty important I get it right so I was hoping for some sage advice. We have created a calendar using jQuery, C#, .Net & SQL Server 08. The calendar works but now we are wanting to add email, SMS and voice-call reminders. We are a small company and can do whatever we need to do with no restrictions on our IT environment. I have some base-line experience with Unix servers but would prefer to stay in the Micro$oft universe if it is prudent to do so. I know how to add the API calls and services to initiate these reminders (using built in email services for email and Twilio.com for SMS). I am asking for advice about how to approach a reliable and timely listener service that knows when to call the service or API for the reminder before an appointment. EG. SMS: "You have a conference call in 30 minutes." I have done some research, but it is hard to know what is a proven reliable approach. What I am looking for is an experienced opinion on a good (or the best) strategy for implementing a solution that will reliably listen for appointments and dispatch the reminders when needed.

• Server was unable to process request.

  - by Naveen

  I have a vb.net web application that talks to a web service. I get the following error if I try to connect to the web service. System.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: Server was unable to process request. The strange thing is it is working fine on one of the set of servers and on another set of servers, we get this error. The only notable difference between the servers is in the authentication setting in IIS. The server where the it works fine we have the ASP.Net Impersonation disabled, but on the other server I get an error the moment I disable the ASP.Net Impersonation.
