• How to transition to Comcast with static IP address [migrated]

  - by steveha

  I have my own email server in my house, on a static IP address. I have had business DSL for over a decade, but I also now have Comcast business Internet. I want to transition from the DSL to the Comcast, and I have some questions. I have a domain name, my own mail server, and a firewall (a PC with two network interfaces, running Devil-Linux). I need to make sure I understand how to set up the Comcast cable box, and how to set up my firewall. First, do I need to change any settings in the cable box? Currently I have only used the cable box by plugging in a laptop, with the laptop doing DHCP. I think I can leave the box alone but I would like to make sure. Second, I'm not sure I understand the instructions Comcast gave me for setting up the firewall. My DSL provider gave me the following information: static IP address, net mask, gateway, and two DNS servers. Comcast gave me: static IP address, routable static IP address, net mask, and two DNS servers, and told me to put the "static IP address" as the "gateway" on the firewall. Is this just Comcast-speak here? Does "routable static IP address" mean the same thing as "static IP address" in my DSL setup, the end-point address that I should publish in the DNS MX records for my email server? Or should I publish the "static IP address", and Comcast will then route all its traffic over the cable box? My plan is: first, I'm going to configure another firewall, so I have one firewall for the DSL and one for the Comcast (rather than madly editing settings to switch back and forth). Then I will publish the new Comcast static IP address as a backup email server address in the DNS MX records, wait a while to let it propagate, and then switch my home over from the DSL to the Comcast. Then I'll change DNS to make that the primary mail address and the DSL the secondary, let that go a while and make sure it seems reliable. Then I'll remove the DSL from the DNS MX records completely, and finally shut down the DSL service. (I thought about keeping the DSL as a backup, but the reason I'm leaving DSL is that it has become unreliable; and I have heard that Comcast business Internet is reliable.) Final question, any advice for me? Anything you think might be useful, helpful, or educational. Thanks.

• Watchguard firebox: public IP addresses behind firewall with as much usable IP addresses as possible

  - by martinezpt

  Our ISP assigned us 16 public IP addresses that we want to assign to hosts behind a Watchguard firebox x750e. The IP addresses are: x.x.x.176/28 of which x.x.x.177 is the gateway. The hosts will be running software that needs to be directly assigned the public IP address so 1:1 NAT is not an option. I found this document that gives examples on how to assign public IP addresses to hosts behind the firewall, using an optional interface: http://www.watchguard.com/help/configuration-examples/public_IP_behind_XTM_configuration_example_(en-US).pdf However, I can't implement scenario 1 as it won't allow me to use the same subnet on both interfaces. As for scenario 2, splitting the address range into 2 subnets will decrease the usable hosts on the optional interface to 5 (8 - network - broadcast - optional interface ip). I'm convinced that there must be a better way to address this problem and maximize the number of usable IP addresses but I'm not very familiar with this specific firewall. Are there any suggestions on how to keep the hosts behind the firewall with public IP addresses while maximizing the usable IP addresses? thanks

• Debian as USB hardware portable as possible

  - by James Mitch

  I have recent hardware, 64 bit, pae and so on. But I'd like to have my Debian installation on a USB HDD. Installing Debian to USB is solved. I used the i386 architecture image. But a pae kernel has been installed. I want to be able to travel with my USB HDD and therefore I want best possible hardware compatibility. My friends and family have sometimes older hardware, but always i386, just sometimes without 64 bit or pae. Never met someone with sparc or other architectures. What should I do to get non-pae kernel and maximum hardware compatibility?

• Block web browsing by older browsers

  - by Eamon

  Given the vulnerabilities in older versions of IE, I want to enforce a rule that only the latest IE or Firefox is used to browse the web. I can't ensure that everyone's PC is up to date, so is there a firewall that will let me write a rule to restrict the version of the browser that can make requests through the firewall? Our current firewall is from Watchguard

• Blackberry device GPS hardware specs [closed]

  - by colemanm

  I'm looking to find out detailed specifications for the built-in GPS hardware in the Blackberry Bold and Curve devices (9000 and 8350). RIM's documentation includes just a rudimentary description of the specs, but I'm looking for things like the actual detailed hardware/chipset info so we can research the accuracy needs for some upcoming projects we have. Knowing simply "A-GPS support" isn't really good enough... Does anyone know of any resources for finding advanced specs for built-in Blackberry hardware?

• Unable to access internal network through PfSense WAN port

  - by Sean

  Our branch office is unable to connect to our internal network for some reason. However we can connect to the branch office domain controller from behind PfSense. The following is our setup: |Branch DC - 192.168.0.101 | |Branch Firewall - 192.168.0.2 | |(Internet) | |Local Firewall - 192.168.3.1 | |PFSense WAN port - 192.168.3.100 |PFSense LAN port - 192.168.1.1 | | DC1 - 192.168.1.2|DC2 - 192.168.1.4 Branch DC can ping and connect to PFSense WebGUI on the WAN port successfully (we set this up using the PfSense documentation). DC1 and DC2 can connect outbound to the Branch DC. There seems to be a rule that prevents internal access on the WAN port. However our rules are set to allow all traffic on the LAN and WAN ports. It would be ideal to just disable the firewall altogether since we already have a firewall but when we do this, PfSense doesn't allow any internal traffic at all. I look forward to any assistance and thank you ahead of time.

• RAID - software vs. hardware

  - by Robert MacLean

  I have always used hardware based raid because it (IMHO) it's on the right level (feel free to dispute this) and that OS failures are more common to me than hardware issues. Thus if the OS fails the raid is gone and so is the data, where on a hardware level regardless of OS the data remains. However on a recent Stack Overflow podcast they stated they would not used hardware raid as the software raid is better developed and thus runs better. So my question is, is there any reasons to choose one over the other?

• Easy Install Resets Hardware Settings

  - by bob5972

  I think there's a problem with the Easy Install setup. I selected "Installer disc image," and it came up and said that it would use "Easy Install," I think I hit next, and then I went back changed my mind, and selected "I will install the operating system later." After finishing the wizard, I think it still went and ran Easy Install, because it auto-installed VMware tools and I never got to select anything for my windows setup. Then, when it was finished, all the hardware changes I had made were lost. The RAM was changed from 2 GB back to the default of 1 GB, my CD ROM drive was set back to "Use a Physical Drive" and "Connect at Power On", and the Floppy Drive was also set to "Connect at Power On", after I disabled them. I was trying to install Windows 7, and I wasn't sure if I could change the RAM settings after installation without needing to reactivate it, so I deleted the VM and tried to start over. This time, the "Installer disc image" had my Win7 image pre-selected, so I clicked "I will install it myself later," set my hardware again, and tried to boot off my CD. Again,it did an Easy Install, and reset my RAM and my drive settings. So I deleted it again and the third time it still had the Win7 image pre-selected, but this time I unplugged all the drives and let it try to boot off the empty harddrive and fail, and made sure it kept all my hardware settings. Then, I powered it off, put my Win7 image in the guest CD ROM, and powered it on. This time it finally let me run the installer and pick my language, and type a user name. This time when I powered it off it kept my hardware settings. I can duplicate the error by doing exactly the steps above. Creating a new VM, selecting my "Installer Image," hitting next, going back, selecting "I will Install it myself," and then finish the wizard, and customizing my hardware right before the end, setting the CD Rom drive to the same installer media, and setting "Connect on Power On." (If I start it without the CD ROM in the first time, it doesn't do it). When I power on, I'm not prompted for any install information (like language and user name), and when it runs the first timemy hardware choices are reset (like the RAM back to 1 GB). If it helps, I'm running VMware Workstation 7.0.1 build-227600 on Gentoo Linux

• Is Hacom Mars II Dual Blade good ?

  - by Joachim H. Skeie

  I am considering getting a Hacom Mars II Dual Blade for use as a firewall in a data-center for one of my colocated solutions. As the 1U enclosure have two identical firewalls, I am intending to use one of the firewalls as the external firewall using packet-filtering and load balancer (balancing load for my front-end nodes), while using the second as the internal firewall (as an application gateway). But I have no experience with Hacom, or pfSense firewalls. They do look really good on paper, but how are they in practice ?

• Linux servers seeing bad download performance behind Sonicwall firewall

  - by Joshua Penix

  I'm working with a pair of co-located CentOS Linux servers sitting behind a Sonicwall PRO 2040 Enhanced firewall running in transparent bridge mode. These servers are having a strange problem downloading files more than a few megabytes in size. For example, if I try to wget or FTP a copy of the Linux kernel from kernel.org, the first ~1-2MB will download at 600+K/s, and then throughput will drop off a cliff to 1K/s. I've reviewed all the firewall configuration settings for anything suspicious, but found nothing. More interestingly, I performed the same download with a Windows server sitting behind the same firewall, and it sailed right through at 600+K/s the whole way. Has anyone seen this? Where should I start looking to troubleshoot this problem?

• Cloud services can't be reached from complex customer infrastructure

  - by Nock

  We have several services running on a cloud, they all are hosted on Windows Server 2012 R2, have public IP address and specific port. Some of our customers can't reach them because for "some reason" the ports are cut between a firewall between them and us. (some customers are using a shared internet connection in a multi tenant office and they can't change firewall communication) Well, you get it, we don't have the possibility to make all the firewall "allowing" the communication. My customers all runs Windows 7 at least. What is the best counter solution in such case, using Microsoft (Windows Server) technologies? The best would be some kind of tunneling communication or VPN, but the customer should also be able to access his/her enterprise resources. Bby the way, today we using IPSec using Windows Firewall to secure the communication, is IPSec tunneling a solution for us? Otherwise, is there a service in Windows to enable some kind of VPN between a client and a server but only for a given set of servers?

• Squeezebox server on Mac OS 10.6

  - by jonathancaryl

  I want to run Squeezebox server on my Mac running OS 10.6 Snow Leopard. The Firewall settings on 10.6 now let you speciy by Application things that are allowed to connect through the firewall. But Squeezebox server isn't an application, so I can't select it. If I turn the firewall off, it works fine. This is a reasonable step for a desktop (as it's always connecting to the 'net through the router's firewall) but on a laptop that connects via public WiFi it doesn't seem like a good idea. Help!

• Server Hardware on the Desktop

  - by jcnnghm

  When I rebuild my desktop, I'm thinking of using server hardware instead of desktop hardware. I want to do this so I can easily add a lot of ECC memory (~20GB), and possibly more than one processor. I know that video hardware could be a problem, especially because I use 4 monitors. I should be fine with this, as long as I have two pci-e channels. Are there any downsides to doing this? Anything I'm not seeing?

• Google Chrome giving error 138

  - by gsingh2011

  Google Chrome randomly stopped working one day and is giving me this error: Google Chrome is having trouble accessing the network. This may be because your firewall or antivirus software wrongly thinks that Google Chrome is an intruder on your computer and is blocking it from connecting to the Internet. Here are some suggestions: Add Google Chrome as a permitted programme in your firewall or antivirus software's settings. If it is already a permitted programme, try deleting it from the list of permitted programmes and adding it again. Error 138 (net::ERR_NETWORK_ACCESS_DENIED): Unable to access the network. I didn't make any changes to my firewall settings between the time it was working and when it wasn't working. I'm using the default Windows Firewall. I added Chrome to the allowed programs and restarted, but that didn't fix the error. I even reinstalled Chrome completely and that didn't work either. Any help would be appreciated. EDIT: I forgot to mention that Firefox and IE9 work fine.

• Windows Server 2008 R2 bare metal restore to different hardware

  - by S Falken

  Scenario: I have a Windows Server 2008 R2 x64 installation whose main disk drive is now 7 years old and showing signs of age. For the last couple of months it's been displaying increased errors and requirements to run checkdisk. I have successfully created a bare metal restore (BMR) image on a separate data drive on the server, which can be seen from the Windows Recovery console; I tested it by booting to and using the Windows Server installation DVD's recovery utilities. The BMR image includes the system drive with boot partition, system state, and the D:\ drive of the server, which is where I have followed the practice of installing any program that does not require a C:\ installation path. Therefore, the BMR includes both the C:\ and D:\ drives, system state and boot partition. The C:\ drive is a 7-year old Seagate 160GB. The D:\ drive is a rather newer 120GB Western Digital. I have purchased a 128GB solid state Samsung 830 that I want to restore these partitions to, using the BMR. Questions: In the above-referenced article, Microsoft seems to be indicating that I am only able to restore to like-kind hardware, which doesn't help at all and is difficult to believe. Is this really true? I've cleaned these drives up and minimized the size of partition they require. C:\ will need about a 70GB partition, and the data on D:\ will need about 50GB. Will Windows Server backup allow me to restore the BMR to newly-created partitions on the SSD, discarding extra space? I don't need a "how-to": I just need an "is it possible". Justification: Before posting this question, I checked ServerFault articles with the following titles, but none of them were about this exact scenario: Restore SBS 2008 Backup to Same Hardware but Different Disk Configuration Restoring Windows Server 2008 to different hardware - OEM License Restoring II6 server after a hardware failure windows 2008 r2 fail to restore Domain controller failed to restore using windows backup tools How does restore to dissimilar hardware work? Migrating Windows 2008 R2 from a PC to a different PC TFS 2005 Server restore from one hardware to another I also researched Microsoft but only received an oblique answer which was not precisely aimed at my question, at the following URL: http://support.microsoft.com/kb/249694#method3

• Cannot connect to MySQL on RDS (Amazon Web Services) from my laptop

  - by Bruno Reis

  I'm having some trouble connecting to a MySQL 5.1 server on an RDS instance on AWS from my laptop. The detailed description of the problem is here: https://forums.aws.amazon.com/thread.jspa?messageID=323397 In short: I have 2 MySQL servers, both with the same db configuration and firewall (security group) configuration. One of them works fine: I can connect to it from my EC2 instances (ie, from inside the AWS cloud) and from my laptop. The other one doesn't: I can connect from my EC2 instances but not from my laptop. The symptom: a connection attempt from my laptop just hangs, and then times out, as if there was a firewall blocking me (ie, silently dropping my SYN packets). I must say that everything has been working fine for a very long time, and this problem began suddenly, 3 days ago, without any modifications to DB parameters or the security groups. My current analysis of the situation: The firewall (ie, security group) cannot be the problem: both MySQL servers share the same firewall configuration -- I can connect to one of them but not to the other. Later on, I even added a rule to allow inbound connections from 0.0.0.0/0 (ie, I turned off the firewall), and nothing. Oh, I also created a new, fresh security group and changed this instance's SG to the new one (to which I first added my ip address, and then 0.0.0.0/0) but still nothing. The credentials cannot be the problem: I use the same from my laptop and from my EC2 instances -- and the user (which is what Amazon calls master user), in the database, has a host of '%'. MySQL is not blocking my IP due to, say, too many failed connection attemps: I've FLUSH HOSTS on the database, and also I tried to connect using many different source IP addresses, even from all around the world through a VPN proxy service. What could I be missing? I'm asking here because it's been about 36 hours since I've posted on AWS forums but got no answer at all over there... someone here might have a solution! Any input is really appreciated, I'm out of ideas. Thanks!

• how can 192.168.2.10 talk to 172.18.156.65 ?

  - by steve

  from what i understand, all computers need to be in the same subnet /24 so how would i get a computer to be able to connect to another computer that is set as 172 ? one computer is behind a firewall, the other is connected to a HUGHES sat dish and has the IP of 172 would I need to setup a ROUTE in a firewall between the 2 computers, to say "if you are trying to get to 172.18.156.65 then use the ip address 192.168.2.65 and translate it to 172.18.156.65" the firewall is a netgear, if I should use a ROUTE, then I'll try to learn it from the manual thanks

• How to turn iptables stateless?

  - by tex

  Hi, I'm running a Linux server that - from time to time - faces heavy load and the conntrack table overflows. Since it's iptables firewall ruleset is very simple I'd like to turn it to stateless mode. I know that iptables can operate in stateful connection tracking mode and in a stateless mode. My firewall rules are all in place I'm pretty sure that they are stateless but my question is how can I verify that the firewall is really operating in stateless mode?

• Sending email with Windows 8 Mail (Modern UI) being blocked by AVG Firewall

  - by Riaan

  I've setup my Outlook.com email address in Windows 8 Mail (Modern UI) but is unable to send and receive emails when my AVG Internet Security 2012 Business Edition's Firewall is enable. When I disable the firewall, the emails are coming through and are being send. I know that I can most probably open the ports for IMAP on the firewall, but instead I would like to permit the application. Where/how do I find the application path for Windows 8 Mail (Modern UI) to allow all network traffic? (AVG did not show its normal Allow/Disallow notification for 1st time communications) Any advice would be appreciated.

• MAC-Address based routing

  - by d-fens

  Here is what i want to do: I have a bunch of systems, some might have the same Public-IP, i disable ARP. I have a Firewall (either IP Layer or bridge-FW) between these systems and the internet. Depending on the destination port of incoming IP-Packets to some of these Public-IPs i want to set the destinsation-Ethernet-Adress. So for instance System A has IP 8.8.8.8, mac de:ad:be:ef:de:ad, arp disabled System B has IP 8.8.8.8, mac 1f:1f:1f:1f:1f:1f, arp disabled Firewall has IP 8.8.8.1, arp disabled on that interface Incoming packet to IP 8.8.8.8 tcp dest port 100 Incoming packet to IP 8.8.8.8 tcp dest port 101 Firewall sets dest-mac for 1.) - de:ad:be:ef:de:ad Firewall sets dest-mac for 2.) - 1f:1f:1f:1f:1f:1f Second scenario: System A and System B establish outgoing TCP-Connections, and the firewall matches the dst-mac of the incoming IP-Packets (response packets) to the senders-mac address. is this possible in any way with linux and iptables? edit: i read ebtables might "work" in a hackish way for this purpose but i am not sure...

• How can I know if a computer supports hardware-assisted virtualization before I purchase the computer?

  - by Poaters

  I'm an iPhone programmer who is no longer in possession of a personal Mac computer on which to use XCode. I have two Windows desktops, and I would like to run OS X in VMWare rather than purchase Apple's expensive hardware. However, neither of my machines supports hardware-assisted virtualization, which is required to virtualize OS X. I went shopping online for a computer today, since I've been planning to purchase a laptop anyway, but sites like Best Buy don't appear to give any indication of whether or not a product supports this. Is there any other site out there or some trick to figuring this out other than buying the machine and running Microsoft's nifty little detection tool?

• High end mobile workstations with pointer stick

  - by Elijah Lynn

  I am looking for a list of higher end mobile workstations that run Ubuntu/Kubuntu well and also have a hardware pointer stick. Here's an illustration of one (from sciencesurvivalblog): I wouldn't mind getting a Macbook Pro and wiping it but they refuse to use pointer sticks and to me, they are extremely efficient. I see a lot of potential for Lenovo thinkpads as well. System 76 said they have no plans to implement a hardware pointer stick so that leaves them out as well. Any ideas?
