• How can I track down what part of pfsense is blocking website access?

  - by Chase Florell

  I've got a PFSense firewall/gateway on our network. Everything works great except for the fact that I cannot access one specific website. Pfsense is running the following packages Country Block LightSquid nmap notes squid squidGuard Strikeback I can access every single website I've ever tried aside from one that we need for business use (http://bridalnetwork.ca) here's the traceroute frodo:~ chase$ traceroute bridalnetwork.ca traceroute to bridalnetwork.ca (192.197.103.73), 64 hops max, 52 byte packets 1 rohan (192.168.5.1) 6.618 ms 1.662 ms 9.207 ms 2 * * * 3 * * rohan (192.168.5.1) 7.225 ms !H 4 rohan (192.168.5.1) 5.314 ms !H 5.701 ms !H 7.573 ms !H frodo:~ chase$ How can I figure out what the reason behind the blockage is? note: this has been tested on every computer on the network with the same results. ps: the pfsense box is 'rohan' (192.168.5.1) Here's what I get with Squid enabled and here's what I get with Squid disabled

• Securing data sent to an unencrypted WiFi AP

  - by David Parunakian

  The business plan of a project I'm involved in assumes selling certain WiFi-enabled devices to end users. All these devices originally have an unencrypted connection and a standard SSID. The problem is that although the user can connect to it and set both a new SSID and a WPA passphrase, these are being sent to the AP in plain text and thus can be intercepted by anyone nearby with a sniffer. What's the best solution to this problem, and why? Initially set up an encrypted wireless network at the device and supply the user with a printed passphrase Buy an SSL certificate for the AP's default IP address or local domain name (the APs aren't supposed to work as a router and have a captive portal & dnsmasq installed, so all of them can pretend to be myunit.example.com, as far as I understand) Something different Thank you.

• Top ten security tips for non-technical users

  - by Justin

  I'm giving a presentation later this week to the staff at the company where I work. The goal of the presentation is to serve as a refresher/remidner of good practices that can help keep our network secure. The audience is made up of both programmers and non-technical staff, so the presentation is geared for non-technical users. I want part of this presentation to be a top list of "tips". The list needs to be short (to encourage memory) and be specific and relevant to the user. I have the following five items so far: Never open an attachment you didn't expect Only download software from a trusted source, like download.com Do not distribute passwords when requested via phone or email Be wary of social engineering Do not store sensitive data on an FTP server Some clarifications: This is for our work network These need to be "best practices" tips for the end-user, not IT policy We have backups, OS patches, firewall, AV, etc, all centrally managed This is for a small business (less than 25 people) I have two questions: Do you suggest any additional items? Do you suggest any changes to existing items?

• development server?

  - by ajsie

  for a project there will be me and one more programmer to develop a web service. i wonder how the development environment should be like. cause we need central storage (documents, pictures, business materials etc), file version handling, lamp (testing the web service) etc. i have never set up an environment for this before and want to have suggestions from experienced people which tools to use for effective collaboration. what crossed my mind: seperate applications: - google wave (for communication forth and back, setting up guide lines, other information) - team viewer (desktop sharing) - skype (calling) vps (ubuntu server): - svn (version tracking) - ftp (central storage) - lamp (testing the web service) - ssh (managing the vps) is this an appropriate programming environment? and regarding the vps, is it best practice to use ONE vps for all tasks listed up there? all suggestions and feedbacks are welcome!

• Server vendor that allows 3rd party disks

  - by Alvin S

  As noted here, Dell is no longer allowing 3rd party disks to be used with their latest servers. As in, they don't work period. Which means that if you buy one of these boxes and want to upgrade the storage later, you have buy disks from Dell at significant premiums. Dell has just given me a very strong reason to take my server business elsewhere. My company buys (instead of leasing) our servers, and typically uses them for 5 years. I need to be able to upgrade/repurpose storage periodically, and do not want to be locked in to whatever Dell might have in stock, at inflated prices to boot. As you will see in the comments of the above link, it seems HP is doing the same thing. I am looking for a server vendor that offers 3-5 year warranty with same day/next day onsite service, and allows me to use 3rd party disks. Suggestions?

• How to efficiently merge a lot of vCard files for the same person?

  - by mihi

  I currently have contact information at several places: old PDA's address book mobile phone's phone book (primarily name, phone number) email client's address book (primarily name, email) web mailer's address book (primarily name, email) instant messenger's contact list (primarily name, im, email, birthday) And there are several social or business networking sites on the Internet where contacts provide information about themselves, like LinkedIn or XING. All those sources can export as vCard, but as you might imagine, I get a lot of vCards for the very same contact that way. Are there any tools where I can import them and then merge them (it may ask me which phone number is more current in case of field clashes of course)? Bonus points if it can track which information I have discarded so when I re-export all information from one of the sources I can't import to (networking sites), it won't ask me again if I want to overwrite phone number of person X with the same ancient number... I hope you understand what I try to accomplish, if not just ask :-)

• IIS 6 SSL Restore from PFX without Deleting Pending Request

  - by Sev

  I requested a new SSL certificate from a certificate authority, but until they process it my site is losing business. Before doing so, I had backed up the original certificate to a PFX file. Now when I try to restore the backup, it forces me to delete it, or process the request. Since the new one isn't ready yet, is there any way to restore the backup, without deleting the request? Or will it cause any issues if I delete the request to install the new one when it comes in? Server is IIS 6

• BCM 2007 not opening contacts...

  - by Christopher

  Business Contact Manager for Outlook (2007) is refusing to open contacts. This problem appeared this morning on every machine (Windows XP SP3) on our network. The contact list does populate as normal, and contacts can be printed from the context menu, but the form that displays the contact information does not display, and no error message is thrown. I have turned on logging for BCM in the help menu, but nothing is being generated (or, leastways, I cannot find it anywhere). The SQL services appear to have started as normal. Anyone come across this before I take a deep breath and go with my boss' suggestion of "just reboot the server"? Any other information you need? Thanks.

• How do I activate Window 7 for a different computer?

  - by Abdullah BaMusa

  I bought Windows 7 Professional Retail which I installed on my laptop. Now I've decided to move it to be on my desktop PC, so I uninstalled Windows from my laptop, restoring the original OS came with the laptop (Vista Business), and installed Windows 7 on my desktop PC. The problem is that I cannot activate my copy of Windows 7 on the desktop PC. Every time I try to activate it I get the error message The product key you typed cannot be used to activate windows on this computer" and the code of the error is: Code: 0xc004c008 Description: The activation server determined that the specified product key could not be used. How can I solve this problem?

• VirtualBox networking problem, host XP, guest Debian

  - by Silma

  Hi, I'm trying to set up a development environment in a virtual machine on my laptop, with debian os. I have both lan and wlan available on the host machine, yet I can't connect to the internet using either. As I said the host OS is windows XP and the guest OS will be the latest Debian, we downloaded the business card net install so we need internet access from the beginning, besides we need the virtual machine to be visible on the local network (for my fellow developers). We tried host-only networking, NAT, bridging, with proxy (the local network uses a proxy to connect to the internet) and without proxy, nothing seems to work. What else can we do? Thanks a lot.

• Web server (IIS) and database mirroring (Postgresql)

  - by Timka

  Recently our web-server crashed and we had to recover everything from a backup which took the whole day(totally unacceptable in our business). So my question is, how can I create a complete mirror of the server that I can use (switch dns to) in case the same disaster happens in the future? Our main server is on Amazon with Windows 2008/IIS + Postgresql 9.1. I was thinking on creating the same server on a different location as a complete mirror with the database replication. But I'm not sure how to implement IIS instance mirroring over the internet... So my question is, how can I create a complete mirror of the server that I can use (switch dns to) in case the same disaster happens in the future?

• How to install two packages that write the same file

  - by Joel E Salas

  Sirs, a conundrum. I have two packages that each create /usr/bin/ffprobe. One of them is ffmpeg from the Deb Multimedia repository, while the other is ffmbc 0.7-rc5 built from source. The hand-rolled one is business-critical, and we used to just install it from source wherever it was necessary. I can only assume it would clobber the ffmpeg file, and there were never any ill effects. In theory, it should be acceptable for our ffmbc package to overwrite the file from the ffmpeg package. Is there any easy way to reconcile this?

• Why use multiple partitions on a rhel server?

  - by Jakobud

  I'm about to reformat and reinstall CentOS onto an old server. The server runs on a modest 30 node small business network and has a variety of responsibilities including MySQL, a Samba share, DHCPd & SVN/Trac. The old sysadmin had this server setup with almost a dozen different partitions for various things. I'm trying to understand what the advantages of multiple partitions are as opposed to a just one filesystem at /. Speed? Flexibility? Security? It seems like if you misjudge the necessary size for any given partition and it ends up filling up too fast, it requires a sysadmin to go in and expand the partition, etc... Seems like it would be easier if everything was just one flat / filesystem. But I'm sure there are some advantages I'm not aware of. The server is currently running a handful of HDDs raided to ~2TB (raid 0).

• Mysterious login attempts to windows server

  - by Jim Balo

  I have a Windows 2008R2 server that is reporting failed login attempts from a number of workstations on our network. Some event log details: Event ID 4625, Status: 0xc000006d, Sub Status: 0xc0000064 Security ID: NULL SID, Account Name: joedoe, Account Domain: Acme Workstation Name: WINXP1, Source Network Address: 192.168.1.23, Source Port: 1904 Logon Process: NtLmSsp, Authentication Package: NTLM, Logon Type: 3 (network) I believe this is coming from some netbios service or similar (maybe the file explorer), keeping an inventory of its network neighborhood and also trying to authenticate. Is there a way to turn this off without having to turn off file sharing all together? In other words, clients authenticating against file servers that they use is of course no problem, but I want to eliminate clients trying to authenticate to servers that they are not using and have no business with. The above example is only one of thousands of log alerts for similar failed network authentications. What can I do to clean this up / handle this? Thanks.

• Agile sysadmin and devops - How to accomplish?

  - by Marco Ramos

  Nowadays, agile systems adminitration and devops are some of the most trending topics regarding systems administration and operations. Both these concepts are mainly focused on bridging the gap between operations/sysadmins and the projects (developers, business, etc). Even if you never heard of the devops concept, I'm sure that this topic is your concern too. So, what tools and techniques do you use to accomplish devops in you companies? I'm particularly interested in topics like change management, continous integration and automatization, but not only. Please share your thoughts. I'm looking forward to read your answers/opinions :)

• Dual-headed graphics card choice: DVI & VGA with 512MB _or_ DVI & DVI with 256MB

  - by TimH

  Which would you choose? Some more detail: I can choose between: A dual-headed card with both heads DVI but only 256MB of memory A dual-headed card with one VGA and one DVI, with 512MB of memory. Both monitors are 1600x1200 I'll be doing mostly business app development on the computer. No gameplay or advanced graphics work. It's running Win7 and is a quad-core i5. I'm thinking of going with 256MB one, just so both displays are DVI and I don't have to shift between sharp & blurry when I look from one screen to the other. But I'm not sure if the additional RAM would be a huge boon for some reason (Win7 GPU acceleration, for example? But with a quad-core, who cares?).

• Epson XP-600 will not print properly with all new ink recently installed

  - by Joy

  I just installed brand new Epson 273 ink cartridges ($64 worth!) in my Epson XP-600 printer. One box had all the colors plus black, and one had the fatter black cartridge. I am not getting ANY black print on paper, although, when I lift the cartridges out, they show ink inside. Now the yellow is saying LOW though all cartridges are less than 2 weeks old. I only use this printer sparingly—not for business or work reasons. I am ready to scream, as the ink cost almost as much as the actual printer (which is barely 7 months old)! Any ideas on how to solve this issue?

• Purging old Exchange email/content on SBS2003

  - by Aitch

  We have a Windows SBS 2003 server that used to manage email, calendaring and such like for a small organisation via Exchange. We successfully migrated everything to Google Apps for Business about 18 months ago. The server only provides local network services now. We have backed up and virtualized this machine and would now like to purge any residual mail to save disk space and speed up backup etc. The disk space is such that I believe the Exchange mail is still on there somewhere. I've stumbled through System Manager and poked about but cannot confirm whether this is the case. Where would this live and how might I go about it? (Disclaimer: I'm not a Windows admin, Linux is my thing...)

• How to legitimately work around ISP rate limits

  - by Derek Ting

  A lot of ISP rate limit the amount of e-mails that is sent from a particular IP address. What is the proper way to get around that rate limit? Our company has an iPhone application that sends many e-mails because of our large user base and many e-mails go to different ISPs that rate limit the number of messages coming from a specific IP. We do not send spam and we are a legitimate business. However, is there a better way to resolve this limitation rather than just getting a ton of IP addresses? Ideally, I wouldn't want to rely on a third party service to send mail. However, if its the only possible solution, we would consider.

• Dialog box keeps asking for password

  - by hossam-khalili

  I am running Windows 7, Outlook 2007 (Office 2007 pro) and I'm connecting to our Exchange Server 2007 which is part of Small Business Server 2008. Outlook 2007 on one client keeps asking for the password to the remote access URL. If I simply click cancel it's OK for a few minutes. Entering the password and clicking the save PW box does no good. Sometimes clicking cancel results in another dilog box asking the same thing and I may have to click cancel several times to get it to go away for a while. Occasionally Outlook may actually go into a mode where it says it needs the password typed so I click the link which brings the dialog back but simply clicking cancel will make Outlook connect again. Can anyone help me? Thanks!

• Print spooler consumes over 1GB of memory

  - by Stephen Jennings

  Suddenly, on a Windows Vista Business workstation I manage, the Windows print spooler service is consuming over 1GB of memory. I got the call this morning that the user could not print. I discovered all printers were missing from the Printers applet in Control Panel. I rebooted the machine, and at first the printers were still missing, but after a few minutes (and much banging my head against the wall) they suddenly appeared. I stopped worrying about it until later today it happened again to the same workstation. To my knowledge, nothing has changed on the computer. No new printers have been added, no new print drivers would have been installed, and no new software is being used. I tried clearing out the spooler folder (C:\Windows\System32\spooler\printers) which did have four print jobs from this morning, but the problem persists after restarting the spooler service. When starting the service, it starts out using 824 KB of memory, then after about 20 seconds it starts creeping up about 10MB each second until it stabilizes around 1.8GB.

• Dell D620 Windows 7 Blank screen

  - by Dave Arkell

  When I installed Windows 7 on my Dell D620 it was all fine until a couple of days later most times when I either shut down or suspend (by closing the lid). When I unsuspend or startup the computer, there is often a completely blank screen (can't see post screen or anything), and restarting doesn't help. I've found that I can eventually bring it back up again by suspending and unsuspending a few times, but obviously this is not ideal. Has anyone else experienced this? I think it is a driver issue, that somehow the driver is putting the video card into a certain mode that it forgets how to get it back out of. Any ideas on a better solution than my switching off and on business? Edit: Turns out that the video card had burned out! IT managed to get me a new mainboard sorted for me.

• Using FTP to update files on a server

  - by Neville

  I know the FTP username and password for a site we own and need to know how we can update some files on the server. It seems quite a small thing to do and I'd like to have a go at doing it myself. A few years ago a friendly local guy help set up a website for my wife's floristry business. The site has a "contact us" page, and messages are forwarded to our home email address. We've now just changed our home email, and so I now need to reset the forwarding function on the website. The helpful local guy seems to have moved away, or retired - there's no way I can find him now. I tried to get help on how to change the forwarding address from the hosting people, but they say they can't help me. How do I go about updating the pages on the site? A step-by-step guide on how to do it would be great.
