• Ad Agency storage/file server +backup needed (NAS or something else?)

  - by Rob

  Looking for a "this is all you need" recommendation. We're a small ad agency with both mac & pcs that access and share files from a 3 yr old Windows 2000 box (no server software). We currently have 1TB on the "server" and back it up to 2 different Seagate Free Agent Pro 1TB external drives. But we're low on space and are looking for something that's bigger, that we can still access from Mac & PC, EASY backup system, secure from viruses, firewall enabled. Not sure if a NAS will work or if we should have a real server. We don't really get on that box except to restore files, or run Norton on it. I hope I've provided enough for a general recommendation. Thanks. Rob Phx

• How to prove that an email has been sent?

  - by bguiz

  Hi, I have a dispute on my hands in which the other party (landlord's real estate agent) dishonestly claims to not have received an email that I truly did send. My questions is, what are the ways to prove that the email was indeed sent? Thus far, the methods that I have already thought of are: Screenshot of the mail in the outbox Forwarding a copy of the original email I am aware of other things like HTTP/ SMTP headers etc that would exist as well. Are these useful for my purposes, and if so how do I extract these? The email in question was sent using Yahoo webmail ( http://au.mail.yahoo.com/ ). Edit: I am not seeking legal advice here, just technical advice as to how to gather this information.

• Log monitoring using Zabbix

  - by Supratik

  Hi I am monitoring logs using Zabbix. I am trying to monitor a log file using Zabbix 1.8.4. I created an item using the following details: Host: Zabbix server Description: logger_test Type: Zabbix agent (active) Key: log[/tmp/scribetest/test3/test3_current,error,,100] Type of Infromation: Log Update interval (in sec): 1 sec Keep history (in days): 90 Status: Active Applications: Log files I created a trigger and attached it with the item logger_test using the following details. Name: logger_test_trigger Expression: {Zabbix server:log[/tmp/scribetest/test3/test3_current,error,,100].str(error)}=1 Severity: disaster The above settings works fine for the first time but next time the trigger shows ZBX_NOTSUPPORTED and after that item also shows "not supported" message. Can you please tell me if anything I am doing wrong here ? Warm Regards Supratik

• Keeping Private SSH Keys Safe

  - by Carmen

  I have a central server where I stored all the private ssh keys to the different machines that I want to ssh to. Currently, only sysadmins have access to this 'central' server. Given the above scenario, I like to ask the following questions: How do you protect your private ssh keys? I read about ssh-agent but I am not sure how to use it or if it can be used in this situation. If a sysadmin leaves and he copies all the private ssh keys, then he has access to all the servers. How do you deal with this situation?

• Scheduled Jobs during hours of autumn time change

  - by NealWalters

  I'm wondering how other people deal with this scenario. What if you have a job scheduled to run at 1:30 am. In the autumn, when time changes, the hour of 1:00:00 to 1:59:59 repeats itself and so that job would run twice. Could be Windows Task Scheduler, SQL Agent or any other scheduling tool. Most of these tools seem to be based on machine time, not UTC time. If I told it to run the job at UTC time each night, then I wouldn't have the duplicate hour issue.

• Configuring SASL support in libmemcached

• Start jade via batch script as service on windows server 2012 amazon ec2 instance

  - by E. Lüders

  I would like to start the Jade agent platform with a batch script on an windows server ec2 instance as a service. The reason for this is, that I want to start jade automatically at system startup. For creating the service I use nssm. However so far its working fine and the service is created. When I want to start the service I get an error message: Windows could not start the NAME service on Local Computer. The service did not return an error... My batch file contains only one line: java jade.Boot -platform-id P%random% If i execute the script via cmd it works fine. Anybody got an idea why this is not working if I start the batch script as a service?

• How can I flush my ssh keys on power management activity?

  - by Sam Halicke

  Hi all, Using ssh-agent and private keys per the usual. Everything's working as normal. My question regards best practices on flushing keys from ssh-add on activity like sleep, suspend, hibernate, etc. I thought about writing a simple wrapper around those commands, but then wondered if are they even called? Or does the kernel initiate this activity directly? Are the PM utilities strictly userland? I would like this additional layer of security beyond locking my screen, etc. and was wondering if anyone else had solved this elegantly or has best practices to recommend. Thanks.

• sql server log shipping

  - by voam

  I am setting up log shipping with two 2008 sql servers connecting with a vpn. As far as I know as long as the sql agent is able to access the share on the primary/secondary servers everything will work. When I set up the Log shipping on the primary server using SQL Mangagement Studio, before I can set any of the "Secondary Database Settings" it asks me to connect to the secondary server. But I really don't want to open up the connection to the secondary server. I will be initialing this secondary database with a backup so as long as the transaction logs get copies everything should work. How to I work around the GUI not enabling any of the settings for the secondary server until I actually connect to it? Thanks in advance!

• Can I pass the LHS of a cfengine3 processes: line to the RHS?

  - by joeforker

  I'm using cfengine to start the foobar process. Apparently the LHS is discarded when I use process_select? Can I simply pass the LHS to a function, rather than having to put the command match pattern in a body argument? bundle agent foobar { processes: "foobar" # documented way would be to use .* here process_select => command("foobar"), restart_class => start_foobar; commands: start_foobar:: "/usr/bin/foobar"; } body process_select command(c) { command => "$(c)"; process_result => "command"; }

• Can you specify git-shell in .ssh/authorized_keys to restrict access to only git commands via ssh?

  - by Matt Connolly

  I'd like to be able to use a ssh key for authentication, but still restrict the commands that can be executed over the ssh tunnel. With Subversion, I've achieved this by using a .ssh/authorized_keys file like: command="/usr/local/bin/svnserve -t --tunnel-user matt -r /path/to/repository",no-port-forwarding,no-agent-forwarding,no-X11-forwarding,no-pty ssh-rsa AAAAB3NzaC1yc2EAAAABIetc... I've tried this with "/usr/bin/git-shell" in the command, but I just get the funky old fatal: What do you think I am? A shell? error message.

• How to set up mysql storage for certain rsyslog input matches?

  - by ylluminate

  I'm draining various logs from Heroku to an rsyslog linux (ubuntu) server and am starting to have a little more to bite off than I can chew in terms of working with my log histories. I am needing to be able drill back in time based on more flexible details and more flexible access than what the standard syslog file(s) provide. I'm thinking that logging to mysql may be the correct approach, but how do I set this up such that it pulls only certain log entries into a table based on an identified? For example, I see a long hex string identifying each log entry from a certain Heroku app instance. I assume that I can just pipe those into the mysql socket vs ALL rsyslog input into mysql... Could someone please direct me to a resource that can walk me through the process of setting something like this up or simply provide some details that can help? I have 15+ years of Unix experience so I just need some nudging in the right direction as I've not really done a tremendous amount of work with syslog daemons previously in terms of pooling various servers into one. Additionally, I'd be interested in any log review tools that could make drilling through log arrangements like this more handy for developers.

• Need to set mailx variable to specify the From address

  - by user256817

  Running Oracle Linux 5.8 (which is just re-branded RedHat EL 5.8) I must change the From address. But we have scripts that use mailx which cannot be re-written to use any extra flags, so I'd like to use internal variables instead, which I see on the linux.die.net manpage on mailx is an alternative to the -r flag: -r address Sets the From address. Overrides any from variable specified in environment or startup files. Tilde escapes are disabled. The -r address options are passed to the mail transfer agent unless SMTP is used. This option exists for compatibility only; it is recommended to set the from variable directly instead. (Source: http://linux.die.net/man/1/mailx) How can we use these mailx variables? I tried adding this to /root/.mailrc, no go: set [email protected] I also added that to /etc/mail.rc with no gold. So I am turning to you, SuperUsers...

• Sendmail Alias for Nonlocal Email Account

  - by Mark Roddy

  I admin a server which is running a number of web applications for a software dev team (source control, bug tracking, etc). The server has sendmail running solely as a transport to the departmental email server over which I have no control. We have someone who is still in the department but no longer on the dev team so I need to configure the transport agent to redirect all outgoing email (which would be coming from these applications) to the person that has taken their place. I added an entry in /etc/aliases like such: [email protected]: [email protected] But when I run /etc/init.d/sendmail newaliases I get the following error: /etc/mail/aliases: line 32: [email protected]... cannot alias non-local names So clearly I'm doing something I shouldn't. Is there a way to get aliases to work with non-local names or alternatively is their a way to accomplish my goal of redirecting outgoing mail for this user to another one? Technical Specs if the matter: Ubuntu 6.06 sendmail 8.13 (ubuntu provided package)

• Scaling databases with cheap SSD hard drives

  - by Dennis Kashkin

  Hey guys! I hope that many of you are working with high traffic database-driven websites, and chances are that your main scalability issues are in the database. I noticed a couple of things lately: Most large databases require a team of DBAs in order to scale. They constantly struggle with limitations of hard drives and end up with very expensive solutions (SANs or large RAIDs, frequent maintenance windows for defragging and repartitioning, etc.) The actual annual cost of maintaining such databases is in $100K-$1M range which is too steep for me :) Finally, we got several companies like Intel, Samsung, FusionIO, etc. that just started selling extremely fast yet affordable SSD hard drives based on SLC Flash technology. These drives are 100 times faster in random read/writes than the best spinning hard drives on the market (up to 50,000 random writes per second). Their seek time is pretty much zero, so the cost of random I/O is the same as sequential I/O, which is awesome for databases. These SSD drives cost around $10-$20 per gigabyte, and they are relatively small (64GB). So, there seems to be an opportunity to avoid the HUGE costs of scaling databases the traditional way by simply building a big enough RAID 5 array of SSD drives (which would cost only a few thousand dollars). Then we don't care if the database file is fragmented, and we can afford 100 times more disk writes per second without having to spread the database across 100 spindles. . Is anybody else interested in this? I've been testing a few SSD drives and can share my results. If anybody on this site has already solved their I/O bottleneck with SSDs, I would love to hear your war stories! PS. I know that there are plenty of expensive solutions out there that help with scalability, for example the time proven RAM-based SANs. I want to be clear that even $50K is too expensive for my project. I have to find a solution that costs no more than $10K and does not take much time to implement.

• What to do when a device has no driver for Windows 7 but it has Vista, XP drivers

  - by Mehper C. Palavuzlar

  This has always been a bothersome matter for me. Some devices (printers, scanners, etc.) have drivers for older versions of Windows (Vista, XP, 2000, NT) but no driver for Windows 7. What are my chances to install such devices on Windows 7? Example case: I have a Sharp printer & scanner (Sharp AR-122E N) which I have used for my old Windows XP based PC. Now I want to install it on a Windows 7 x64 based PC. Windows 7 cannot load its driver. I used the original driver CD but when I run the setup.exe (which is included in AR122EN111.exe, 6713KB), it says Cannot install driver on this operating system. Supported operating systems are: Windows 2000, XP, Vista. I tried to install the driver using compatibility settings. I tried Windows Vista and Windows XP SP3, but to no avail. The setup gave the same error. I also googled for Windows 7 driver for "Sharp AR-122E N" but it only listed the original driver that I tried. The official site of Sharp does not even list the driver for this product. In the past, the compatibility setting workaround did work for some devices, but this time it failed. What else can I do to overcome this problem?

• IIS 7.5 fails to open database after computer machine on that database server is working restarts.

  - by Jenea

  Hi. I decided to post this question also here in case the issues we have is related to sql server. There is a problem that bother me for some time. I have an asp.net mvc that uses NHibernate for modeling the database. The infrastructure is the following: Windows 2008 R2 for all virtual machines. IIS 7.5 is working on one virtual machine. Sql Server 2008 is working on another virtual machine. We have couple of databases, two that stores application data and one that registers all unhandled exceptions. Sometimes virtual machine that hosts database server restarts (in the middle of the night, not quite sure about the reason) after that connection to the databases that stores application data is not working and as result there are thousands of unhandled exceptions that get registered in the third database. Important to mention that databases are accessible from Management Studio. The problem is solved by resetting IIS. Connetion are handled via NHibernateUtil class which opens and closes session at each request.

• Laptop authentication/logon via accelometer tilt, flip, and twist

  - by wonsungi

  Looking for another application/technology: A number of years ago, I read about a novel way to authenticate and log on to a laptop. The user simply had to hold the laptop in the air and execute a simple series of tilts and flips to the laptop. By logging accelerometer data, this creates a unique signature for the user. Even if an attacker watched and repeated the exact same motions, the attacker could not replicate the user's movements closely enough. I am looking for information about this technology again, but I can't find anything. It may have been an actual feature on a laptop, or it may have just been a research project. I think I read about it in a magazine like Wired. Does anyone have more information about authentication via unique accelerometer signatures? Here are the closest articles I have been able to find: Knock-based commands for your Linux laptop Shake Well Before Use: Authentication Based on Accelerometer Data[PDF] Inferring Identity using Accelerometers in Television Remote Controls User Evaluation of Lightweight User Authentication with a Single Tri-Axis Accelerometer Identifying Users of Portable Devices from Gait Pattern with Accelerometers[PDF] 3D Signature Biometrics Using Curvature Moments[PDF] MoViSign: A novel authentication mechanism using mobile virtual signatures

• How do I run multiple MVC apps within a subdomain on IIS7?

  - by Matthew Patrick Cashatt

  Hello and thanks for looking. Background I am currently wrapping up a development contract and the client would like for me to push a build of the application to their IIS 7-based server in which they would like to run multiple MVC apps. One of the issues I have off of the bat is that this server is already a subdomain on their larger network. So, if I enter SERVERNAME in my browser, it automatically directs to SERVERNAME.COMPANYNAME.COM. Now, this is just fine if I place my application in the default website/root. In this scenario, clicking a link that requests admin.html directs to `SERVERNAME.COMPANYNAME.COM/admin.html' as usual. BUT they want me to place the app in a subdomain on this server so that they can also run other apps on the same server. So I assume that I need MYAPP.SERVERNAME.COMPANYNAME.COM but I have no idea how to do that. Complicating matters is that my app and the future ones they wish to install are all MVC based which intercepts and re-writes URLs. I assume that this takes care of itself if I can just successfully get my app into a subdomain to begin with. What I have tried Creating a new site on the server in it's own app pool Setting the binding for that site to MYAPP.SERVERNAME.COMPANYNAME.COM Setting the binding for that site to MYAPP Setting the binding for that site to MYAPP.SERVERNAME Setting the binding for that site to MYAPP.SERVERNAME.COM Setting the binding for that site to MYAPP.COMPANYNAME.COM Nothing is working. Am I missing something simple here? Thanks, Matt

• SPF record doesn't work (not sure which DNS server to tweak)

  - by Ion

  Problem: Google (and perhaps others) marks our emails as SPF neutral. Let me give you some background about the setup: initially got a dedicated server (Hetzner) with Plesk installed to host a domain/web application, let's say: bigjaws.com. Plesk automatically creates a DNS zone for it with some records for the various services it provides out of the box, e.g. webmail.bigjaws.com as a CNAME to bigjaws.com to provide Horde/whatever, etc. Let me point out four relevant of these records (where XXX.XXX.XXX.158 is our dedicated IP): bigjaws.com. A XXX.XXX.XXX.158 mail.bigjaws.com. A XXX.XXX.XXX.158 bigjaws.com MX (10) mail.bigjaws.com. bigjaws.com. TXT v=spf1 +a +mx -all The above records are not(?) valid anymore though, because after using this dedicated server for a while, our site got bigger and bigger so we decided to move our operations over to AWS (EC2, RDS, ELB, etc), but we retained the mail functionality as is, i.e. emails from [email protected] are sent by connecting to our dedicated server where Plesk takes care of things. This was decided in order not to setup anything from scratch. Of course for all DNS-related things we now use Route53. In Route53 I have the following records: mail.schoox.com. A XXX.XXX.XXX.158 bigjaws.com. MX (10) mail.bigjaws.com bigjaws.com. SPF "v=spf1 +ip4:XXX.XXX.XXX.158 +mx ~all" From my understanding of SPF, the SPF status should have been passed: I designate that all email being sent by bigjaws.com from XXX.XXX.XXX.158 are valid/not spam (I added +mx there but I'm not sure if needed). When a mail server receives an email, doesn't it lookup the SPF record of the domain and checks against the IP it got the email from? Checking with spfquery: root@box:~# spfquery -ip XXX.XXX.XXX.158 -sender [email protected] -rcpt-to [email protected] StartError Context: Failed to query MAIL-FROM ErrorCode: (2) Could not find a valid SPF record Error: No DNS data for 'bigjaws.com'.

The domain bigjaws.com has authorized static.158.XXX.XXX.XXX.clients.your-server.de (XXX.XXX.XXX.158) to send mail on its behalf, so the message should have been accepted. It is impossible for us to say why it was rejected. What should I do? If the problem persists, contact the bigjaws.com postmaster. Also, here are some headers from an email sent by one of our [email protected] addresses to a gmail.com address (by the way, bigjaws.de listed in the "Received: from" field was the initial domain hosted on the dedicated server before adding the .com one -- both are still listed as separate subscriptions under Plesk).

• AWS: Multi-region setup using single RDS instance

  - by Ion

  I'm trying to scale our web application (PHP, MySQL, memcache) in a multi-region scheme. Currently we are using a setup with two EC2 instances behind an ELB and an RDS instance, all of them in US-EAST (Virginia) region. We would like to have a presence in the EU (Ireland) region as well. This means at least a new EC2 instance there (identical to the others, serving the same application). I have copied the desired AMI, setup the new instance, setup a same ELB configuration (required for SSL termination) and configured latency-based routing in Route53. And it works as suggested. But, clients from EU have speed problems. This is due to the fact that the EU EC2 instances connect to the US-based RDS instance. As far as I know Amazon has not yet enabled RDS multi-region replication. Do you have any suggestions on how to properly speed up the whole setup while using the single RDS instance? Also, any ideas in general on how to scale things up? Ideally we would like to continue using the RDS technology for various reasons. Nevertheless, I am open to suggestions (I guess the next idea would be to host our own MySQL servers).

• Server monitoring for medium scale UNIX network

  - by nbartolomeo

  I'm looking for suggestions for a good monitoring tools, or tools, to handle a mixed Linux (RedHat 4-5) and HPUX environment. Currently we are using Hobbit which is working reasonably well but it is becoming harder to keep track of what alerts are sent out for what servers. Features I'd like to see: Easy configuration of servers. The ability to monitor CPU, network, memory, and specific processes I've looked into Nagios but from what I have seen it won't be easy to set up the configuration for all of our servers ~200 and that without installing a plugin into each agent I won't be able to monitor processes.

• Best way to build / implement a corporate developer Linux distro with multiple kernels?

  - by Garen

  At work we have Linux users who understandably prefer using Ubuntu. Problem is, we also have developer tools that only work with 'officially' supported Linux distributions that use much older 2.6.18 based kernels. (And even if they worked with newer ones, the vendors could always say they won't "support" the software unless it's on one of their 'officially' supported platforms.) We could of course just tell them to use CentOS or something else 2.6.18-based, and I'm sure their response would be something like: "you can take Ubuntu from our cold, dead hands." :) Which brings to me some questions--is there any good/easy/recommended way to run something like Ubuntu as a host VM and Centos 5.x as a guest OS (with which system--Xen,KVM,VMWare, ...?), and then roll that into our own custom internal distribution that could be easily installed? KVM looks like a good high-performance option just recently included in RHEL 5.4, but if hardware support for virtualization like Intel-VT or AMD-V is necessary, then I'd guess only those folks with fairly new PCs will be able to do it. Would be very interested to hear how anyone else has addressed this kind issue. EDIT: The target audience / users of this kind of system would be developers, each one needs to run locally licensed commercial software, so building out some separate beefy central machines isn't an option unfortunately due to license restrictions. Even if that weren't the case, a couple developers could quickly eat up the resources with parallel builds. :) Ideally, I was hoping there was some step-by-step guide out there to build your own pre-built distribution that had e.g. CentOS 5.x and Ubuntu Desktop as a guest.
