  • Connection timeout when trying to SSH

    - by dan
    The other day I tried to connect to my remote server via SSH as i always have. But now when I try to connect it just times out after about 60 seconds. I run service ssh start Which tells me that Job is already running: ssh. I then ran $netstat -tnlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN 1972/dovecot tcp 0 0 0.0.0.0:995 0.0.0.0:* LISTEN 1972/dovecot tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN 2030/mysqld tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN 1972/dovecot tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN 1972/dovecot tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN 2157/perl tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 3028/sshd tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 2273/master tcp6 0 0 :::80 :::* LISTEN 2618/apache2 tcp6 0 0 :::21 :::* LISTEN 2291/proftpd: (acce tcp6 0 0 :::22 :::* LISTEN 3028/sshd I am able to access subdomains on my site, and FTP, but don't have the ability to SSH or even ping remotely. Any thoughts?

  • Is it generally better to compress content on the proxy server or the app server?

    - by Dan
    We're using an F5 for load balancing and SSL proxying. Behind it we're serving up java applications with Tomcat instances. These are fairly small applications - hundreds of concurrent users. I'd like to compress some of the content, and I'm looking for advice on choosing to configure compression on the F5, or on the tomcat instances. Any big factors in the decision, or is it 6-of-one half-dozen of the other?

  • VMWare Newbie - looking for hardware recommendations and help :) [closed]

    - by Dan
    I am looking for some hardware recommendations on an upcoming virtualization project. We are a small company (80 users - 25 in site 1, 55 in site 2) currently using Windows Server 2003 - no VM servers yet. Our AD is setup where site 1 is the root domain and site 2 is a subdomain/subnet - connected by T1 and VPN for failover. The current DC's also server as file servers, print servers, AntiVirus servers. Email is in the cloud. Additionally then in site 1 we have 3 additional member servers - one running IBM Websphere for a customer specific app, one running Infor PowerLink (no real heavy load) and another that we use for Virtual Studio apps and also runs DirSync for Exchange Online. No heavy workloads on any of these machines really. We also have an AS400 box that we run ERP/CRM software on that site 2 connects to over the WAN link. In site 2 we also have a SQL machine that runs on Win2K server. Database files are not large less than 5 GB. Light to Medium workload on this machine. File servers in each site store less than 500 GB data and probably won't grow to more than 1TB in the next 5 years. I am looking to go to VMWare in both sites and virtualize all servers. What recommendations do you have for server, storage hardware? Is it safe to virtualize all of your DC's? Any help or advice would be greatly appreciated. Thanks.

  • Virtualmin - Added Virtual Server - Stopped access to Rails app?

    - by Dan
    Hi, Sorry if this sounds pretty simple, I'm new to Virtualmin and running servers in general. I recently purchased a VPS and installed Virtualmin with no problems. I then installed mod_rails and uploaded my first rails app, which I got working by adding the following to my apache httpd.conf file: <VirtualHost *:80> ServerName testing.mydomain.com DocumentRoot /home/myapp/public <Directory /home/myapp/public> Allow from All AllowOverride all Options -MultiViews </Directory> RailsBaseURI / </VirtualHost> I then tried adding a virtual server through Virtualmin, using mydomain.com. Now, the site this created (plus several sub-servers) and working as expected. However, my original Rails app is no longer accessible. The URL now sends me to the parent application (ie mydomain.com) The Rails app is not located within the parent's application directory, would this be a problem? Can anyone help? Any advice appreciated. Thanks.

  • Use Outlook 2007 to connect to mail using active sync protocol

    - by Dan
    Has anyone tried connected outlook(I am running v2007 on Windows 7) to a mail service using the MS Exchange Active Sync protocol? I know it is intended for mobile devices, but to me it looks like it is becoming the latest 'de facto' mail protocol for email/calendar/contact sync'ing due to the iPhone's support for it. I just think it would be an elegant solution to get my lotus notes mail in outlook(my company uses lotus notes with traveler service installed that exposes mail over the active sync protocol so I can currently read my notes mail via iPhone). This solution would probably eliminate the need for all the hacks needed to connect outlook to 'X' mail (Gmail, notes, etc) So, maybe someone out there has tried this or knows how to do it before spend time on more researching this. Thanks!

  • Can iptables allow Squid to process a request, then redirect the response packets to another port?

    - by Dan H
    I'm trying to test a fancy traffic analyzer app, which I have running on port 8890. My current plan is to let any HTTP request come into Squid, on port 3128, and let it process the request, and then just before it sends the response back, use iptables to redirect the response packets (leaving port 3128) to port 8890. I've researched this all night, and tried many iptables commands, but I'm missing something and my hair is falling out. I thought something like this would work: iptables -t nat -A OUTPUT -p tcp --sport 3128 -j REDIRECT --to-ports 8990 This rule gets created ok, but it never redirects anything. Is this even possible? If so, what iptables incantation could do it? If not, any idea what might work on a single host, given multiple remote browser clients?

  • OSX Keyboard Shortcuts in Dialogs?

    - by Dan Fabulich
    On Windows, every dialog box includes underlined letters that you can activate using the Alt key. I use these "Alt" keyboard shortcuts all the time; I'm missing them as I'm trying to switch to OSX. On OSX, all I can find is Tab navigation, which requires you to press Tab seven or eight times to get anywhere in most dialog boxes. (And even that is hidden by default: you have to enable "Full keyboard access" in the "Keyboard & Mouse" control panel to be able to Tab between buttons.) Is there some way I can get something like the Windows Alt accelerators for OSX dialogs? I'm willing to write Automator code, download/purchase software, etc. Specifically, I'm imagining maybe something where you do some shortcut command and then start typing the name of the button, and hit Enter to push the button...?

  • Outlook 2007/2010 autodiscovering old Exchange info

    - by Dan
    I currently have an Exchange setup as follows: two Exchange 2003 servers clustered together set up as the current mailbox stores, one Exchange 2003 setup as a frontend, one Exchange 2007 set up as a frontend (was set up for testing by my predecessor, never really used intentionally), and now four Exchange 2010 servers - two mailboxes in a DAG and two with Hub/CAS. Everything seems to be working fine with one exception - Outlook 2007/2010 clients are still autodiscovering the test 2007 frontend and not the 2010 CAS array. I know this because there's an expired cert on the 2007 box so the client displays a cert error when you attempt to autocreate the outlook profile. From what I've read, there is an SCP (Service Connection Point) in AD that is pointing to the old server and it is getting returned first, causing Outlook to try it first. How can I prevent Outlook from even attempting to connect to this 2007 box from now on? http://www.msexchange.org/articles_tutorials/exchange-server-2010/management-administration/exchange-autodiscover.html When Outlook 2007 is installed on a domain joined workstation then the Outlook client will query Active Directory for the Autodiscover information. Active Directory will return a list of SCP’s and the Outlook client will automatically select the first SCP in this list. Using the information found in the SCP the Outlook client will contact the Client Access Server for its configuration information and the Outlook client will be configured automatically.

  • Running ssh-agent from a shell script

    - by Dan
    I'm trying to create a shell script that, among other things, starts up ssh-agent and adds a private key to the agent. Example: #!/bin/bash # ... ssh-agent $SHELL ssh-add /path/to/key # ... The problem with this is ssh-agent apparently kicks off another instance of $SHELL (in my case, bash) and from the script's perspective it's executed everything and ssh-add and anything below it is never run. How can I run ssh-agent from my shell script and keep it moving on down the list of commands?

  • Microsoft Excel 2013

    - by Dan LaMoreaux
    We use a spreadsheet as our timecards. The template is stores on the server with links to it on the individual Desktops. I am trying to figgure out the VB so that wnen the cell for username (B5) is blank, the VB will place next sundays date in (B7). After the user enters thier name in B5, I need it to not change B7 again. If I use a formula in B7 "=IF(B5="",TODAY()+8-WEEKDAY(TODAY()),B7)" i need to enable the curcular calcualtions, which don't follow from the template to the spreadsheet, thus causing errors for every individual. Corporate says that they need to be in Excel, because of the import software. Otherwise I'd use Word and the "CreateDate" function. I've been trying to learn the VB to do it, but I was hoping that soem expert could whip out the code in 5 min. flat and just let me disect it.

  • DVD Burning Software compatible with Windows 7

    - by Dan Rigby
    Anyone have any suggestions for good DVD burning software compatible with Windows 7? I've tried ImgBurn and so far have 3 new coasters (it may just be my machine). I'm aware that windows 7 contains some basic DVD burning capabilities, but I'm looking for something a little more powerful. Free software is preferred, but not required.

  • Post Error, Fixed/Removable Media Error

    - by Dan
    Hi, I really do not know what I am missing here. I ordered parts for a new server. The board is an Intel s3420GP. From the diagnostic LEDs I get the error message: 0xB1h which corresponds to "Fixed Media: Disabling fixed media" and 0xB8h which corresponds to "Removable Media: Resetting removable media device." I can not for the life of me figure out what it is talking about. I have two identical motherboards and both gave the error message. I don't have a second CPU yet, so I can't test that. There are no beeps or anything. It seems the server resets every 10 seconds or so (the speaker does work, I put the RAM in the wrong slots on purpose to test this out, and the correct error POST code came up) Please help me, I'm not sure where else to turn or to ask

  • How does Windows Task Scheduler detect that a task is already running?

    - by Dan C
    I have an application on Windows Server 2008 that takes different command-line parameters. For example: myapp.exe /A myapp.exe /B I have created a task scheduler task for each of those. While "myapp.exe /A" is running, I want to prevent another instance of it from starting. However, I still want "myapp.exe /B" to be able to run (again, though only one instance of it at a time). How can I set this up?

  • How can I get past a BSOD 07b when booting from a VHD?

    - by Dan
    I thought I'd be clever and use disk2vhd at the end of my contract to backup my machine so I could easily restore it when I started my new contract, no matter what the buffoons had done with it in the meantime. I didn't count on them losing it. I'm trying to boot this new machine from the VHD. I get the windows logo and then a 07B bluescreen error, something to do with the disk, and it won't boot even in safe mode. The cure apparently is to run sysprep but I can't run that unless I can boot into the VHD so... I can mount the disk, is there a way to modify it

  • What should I know before I set up RAID 6 on Linux?

    - by Dan Ellis
    I just ordered five 1TB drives to install as a RAID 6 array in a Linux server (keeping the existing 1TB drive as a boot disk). I want to use Linux MD for RAID rather than a RAID card, to avoid lock-in. The intended use is for storing filesystems for Xen development environments and an AFP server for iPhoto/Aperture/Lightroom. What things should I know before I set it up? For example, what would be a good choice of filesystem, and what chunk size should I use?

  • Home media storage solution

    - by Dan
    I record lots of personal HD film footage and am looking for a cheap way to store all of this. I take ~120 GB of footage each month, so something expandable would be nice... something that might be able to hold 6+ SATA drives. There is a low load requirement, as there is never more than a user or two... but it should be able to keep up with streaming 2 simultanious HD videos. I don't really want to spend more than $200-$300 on top of the $900 I am thinking of spending for 6X2GB SATA drives@ $150 apiece, but I am willing to pay extra for a quality solution. Should I get a cheap NAS server? a cheap multi-drive external enclosure? should I just get some used systems off craigslist? If it is an independent system I'll probably just throw ubuntu on it since I can maintain that well. Its easy to do a software raid from ubuntu too, if I choose to go that way. Thanks

  • VPN: Does all traffic get routed through the VPN when I am logged in?

    - by Dan
    If I log into a slow VPN with only a 15k/s connection, when I try to go to kernel.org or some other site to download something, is everything getting routed through that other network? (so my max speed for all downloads is 15k/s?) Or are only the DNS requests getting routed and I can still get my normal download speeds I would have been able to before logging into the router?

  • Why is my keyboard acting like the Ctrl key is pressed when I hit an F key?

    - by Dan Tao
    So, I'm gradually getting the hang of the Kinesis Advantage Pro keyboard that my wife bought me for Christmas. I love it so far. But something very strange happened today. (Note: I actually have no idea if this problem has anything to do with the Kinesis keyboard per se. All I know is that I never encountered this problem until after replacing my old keyboard with the Kinesis.) It seems that if I press an F key (e.g., F2), the computer starts acting like I'm holding down the Ctrl key. For example if I click on a link in my web browser, it now opens in a new tab. Or if I hit A all the text in the document I'm editing gets selected. This behavior persists until I manually hit the Ctrl key again. Has anyone seen anything like this before? What could cause such behavior?

  • Windows Task Scheduler does not start task at next run time

    - by Dan C
    I have a Windows Server 2008 SP 2 Task Scheduler task that should run every 10 minutes. The trigger says "At 6:50 PM every day - After triggered, repeat every 10 minutes for a duration of 1 day." Looking at the Next Run Time, it says 6/18/2012 8:00 PM. However, when I let that time pass, the Next Run Time just changes to 8:10 PM but the task has not started and the Last Run Time is unchanged from yesterday. How can I get this task to run every 10 minutes when enabled no matter what. Similarly, I have other tasks that need to run on slightly different schedules: Every 30 minutes (5:30, 6:00, 6:30, etc) Every 30 minutes (5:35, 6:05, 6:35, etc) How can I define these intervals? And why does the task not start at the indicated Next Run Time?

  • this operation has been canceled due to restrictions in effect on this computer

    - by Dan
    I have this HUGELY irritating problem on Windows 7 (x64). Whenever I click on ANY link (that exists on a Word document, excel or Outlook), I get an alert box with the message: "This operation has been canceled due to restrictions in effect on this computer" I have been scouring my settings and the internet for a solution, but to no avail. Has anybody else encounted this problem? It even happens when I click anchors in word documents i.e. I can't even click on an entry in a Table of Contents to go to the appropriate page - I get this same error then. Is this a Windows 7 thing? Anyway to turn this off?
