  • Unmanaged Network Switch vs Managed Network Switch

    - by David
    Currently I have an unmanaged POE switch connected to a Linksys router. I am thinking of upgrading my POE switch to a gigabit POE switch, the only problem is that the switch that I want to get is a managed switch. So here's my question: with a managed switch, can I still connect all of my devices to it and have the devices request IP addresses from the DHCP server within the Linksys router or will the devices request IPs from the managed switch since I believe the switch has its own DHCP server as well?

  • Discover all websites that point to an IP address

    - by crn
    Our company owns over 60 domains and a few external IP addresses (several domains share an external IP address). How do I discover all the domains that use a particular IP address (e.g. 69.x.x.7) without going through the DNS information on each domain? The particular webserver is running Windows 2003 and IIS6. Thanks, in advance, for your help!

  • How should I choose my DNS?

    - by Jader Dias
    When I have to choose my DNS I think that I should consider: Speed Reliability Privacy Control (reports and stats) The main options that come to my mind, and how I weigh them according to the above factors, are: My ISP = faster (closer to me) but less privacy (they can associate my DNS requests to myself) OpenDNS and such = more control and more privacy (all they have is one of my e-mail addresses) Google = less privacy (they can associate my DNS requests to my Google Account and my searches) What weighting factors, or other options, have I missed?

  • Is it worth the effort to block failed login attempts

    - by dunxd
    Is it worthwhile running fail2ban, sshdfilter or similar tools, which blacklist IP addresses which attempt and fail to login? I've seen it argued that this is security theatre on a "properly secured" server. However, I feel that it probably makes script kiddies move on to the next server in their list. Let's say that my server is "properly secured" and I am not worried that a brute force attack will actually succeed - are these tools simply keeping my logfiles clean, or am I getting any worthwhile benefit in blocking brute force attack attempts?

  • Second network card configuration not working.

    - by Sebas
    I have 4 servers running Centos 5. All of them have two ethernet network cards. I have configured 192.168.1.x IP addresses on their eth0 card. They are all connected to the same switch using their eth0 card and they are all working. I have configured 10.72.11.x IP addresses on their eth1 card.They are all connected to the same switch - a different one from the switch used with eth0 card - using their eth1 card and they are NOT all working. Their configuration files is like: DEVICE=eth1 BOOTPROTO=static IPADDR=10.72.11.236 BROADCAST=10.72.11.191 NETMASK=255.255.255.192 NETWORK=10.72.11.128 HWADDR=84:2B:2B:55:4B:98 IPV6INIT=yes IPV6_AUTOCONF=yes ONBOOT=yes The interfase is starting and configured as I need.

  • Divide a network into two subnets of equal size

    - by kylex
    I have been given the following IP 192.168.14.137/25 and asked to divide the network into 2. This is what I've come up with: The subnet mask is therefore 255.255.255.128 The network address is 192.168.14.128 There are a total of 128 available addresses (including the network address and broadcast address) To divide the network we create to subnets: 192.168.14.128/26 192.168.14.192/26 This will have a subnet mask of 255.255.255.192 Am I missing anything, or is this correct?

  • Centos server email delay [closed]

    - by sisko
    I am hosting a website on a CentOS server and all was well until I tried sending emails from my website. I realized it is taking unusually long to send email and the webpage to refresh. I actually timed it at just over 6 minutes to send one email to 3 addresses. I have been able to determine the server is utilizing sendmail but I don't know much else about dealing with server issues on a Centos server. Can anyone please help me out?

  • Assign a secondary IP address to a Windows machine using DHCP

    - by IndigoFire
    Is it possible to configure dhcpd (on a Linux box) to assign a Windows PC 2 separate IP configurations? Right now I've configured the two IP addresses manually and it does exactly what's needed, but I can't figure out how to achieve the same thing with DHCP. For example, is it possible to set up a virtual interface that piggy-backs onto the first interface and gets its own configuration? Alternatively, is it possible to run a script upon getting IP values from DHCP that would then be able to configure the secondary IP?

  • Redirect all outgoing traffic on port 80 to a different IP on the same server

    - by Spacedust
    I have multiple IP addresses on the same server and I would like to redirect all outgoing traffic on port 80 to a different IP on the same server just no to use always main IP. Currently I'm using this: /sbin/iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source IP; and it works well, but it redirects everything and when I make backups over SSH backup it's failing. System: CentOS 5.8 64-bit

  • How to use aliases for remote hosts when accessing locally

    - by alexloh
    I would like to use an alias for a remote host. For example, when instead of "ping giraffe.foo.bar.com" I want to do "ping giraffe", but only when I do it from my own machine. I am able to do this for raw IP addresses by adding an entry in /etc/hosts (ie "123.456.1.0 giraffe"), but it does not seem to work for host names.

  • Modem with support for wired 802.1x

    - by menko
    I'm looking at allowing internet access for only a few scattered users on a school network. One method I'm considering is using 802.1x authentication for the modem. Of course there are simpler options like only allowing specific IP or mac addresses, but policy requires something more secure than this. So, are there any modems with 802.1x wired authentication? All my searching on this yields info about wireless.

  • Determine the percentage of a file that has been ftp'd from client to server

    - by klwillie
    I want to ftp a large file from a Windows client to a Windows server, using their IP addresses. This is on an internet independent network. While the file is transferring, I would like to determine how many bytes have been received by the server. I then would like to use this information to determine in real-time the percentage of the file that has been transferred to the server. Any recommendations as to the ftp command syntax and C# code to achieve this?

  • IP address times out

    - by Werner
    I'm running a dedicated server with a couple of game servers running on 4 different IP addresses. The most network-heavy server times out a few times during peak hours and all other communication (FTP/SSH) through the same IP also briefly times out. Other servers using other IPs are fine and unaffected as well as FTP/SSH using other IPs. The server is running Debian 6. What causes this, and is there anything I can do?

  • SNMP Traps: Telling the difference between sources

    - by MHibbin
    I am logging all incoming SNMP traps to file, for further processing, via: snmptrapd -Lf /path/to/my/file.log So this will log all traps coming in on port 162. Is there a way I can tell the differences between different sources, i.e vendors. I believe this would be the "OID" field but i'm unsure. Any thoughts would be welcomed, if not I will just have to use a lookup with IP addresses, but I'm sure I saw that there is a unique part to each vendor. Cheers

  • Recommendations of mail merge freeware?

    - by Chris
    At work (Exchange server) our team often needs to send emails to 500+ partners. It's currently a very dull job, so I've tried the merge features in Office 2007. However, it can't: Include a merge field in the subject ("Regarding your account: ") Send to semi-colon separated addresses (one line might be "[email protected];[email protected];[email protected]") Send from a particular mailbox account, and store all the sent mails in Outlook. Can anyone recommend any free/affordable software which will work with Exchange and can be used commercially?

    I want to set up a server with a lot of users so that (in order of importance): Users cannot obtain ip addresses of other users with who, or last Users cannot wall Users can write to each other Users are able to selectively mesg n other users, as opposed to simply blocking everyone Point 1 is easily solved by a 660 on wtmp and utmp, but I don't know how to achieve the other points The server runs Gentoo Linux

  • Enterprise IPv6 Migration - End of proxypac ? Start of Point-to-Point ? +10K users

    - by Yohann
    Let's start with a diagram : We can see a "typical" IPv4 company network with : An Internet acces through a proxy An "Others companys" access through an dedicated proxy A direct access to local resources All computers have a proxy.pac file that indicates which proxy to use or whether to connect directly. Computers have access to just a local DNS (no name resolution for google.com for example.) By the way ... The company does not respect the RFC1918 internally and uses public addresses! (historical reason). The use of internet proxy explicitly makes it possible to not to have problem. What if we would migrate to IPv6? Step 1 : IPv6 internet access Internet access in IPv6 is easy. Indeed, just connect the proxy in Internet IPv4 and IPv6. There is nothing to do in internal network : Step 2 : IPv6 AND IPv4 in internal network And why not full IPv6 network directly? Because there is always the old servers that are not compatible IPv6 .. Option 1 : Same architecture as in IPv4 with a proxy pac This is probably the easiest solution. But is this the best? I think the transition to IPv6 is an opportunity not to bother with this proxy pac! Option 2 : New architecture with transparent proxy, whithout proxypac, recursive DNS Oh yes! In this new architecture, we have: Explicit Internet Proxy becomes a Transparent Internet Proxy Local DNS becomes a Normal Recursive DNS + authorative for local domains No proxypac Explicit Company Proxy becomes a Transparent Company Proxy Routing Internal Routers reditect IP of appx.ext.example.com to Company Proxy. The default gateway is the Transparent Internet proxy. Questions What do you think of this architecture IPv6? This architecture will reveal the IP addresses of our internal network but it is protected by firewalls. Is this a real big problem? Should we keep the explicit use of a proxy? -How would you make for this migration scenario? -And you, how do you do in your company? Thanks! Feel free to edit my post to make it better.

  • How to combine AWS and dedicated external servers?

    - by rfw21
    I have an extensive network of servers all currently hosted on AWS EC2. For reasons of cost I plan to gradually migrate to dedicated servers where possible. So: How can I best combine AWS and non-AWS servers in my network? Ideally, I should be able to assign internal IP addresses to the external servers, include them in AWS security groups and ensure that all private traffic between my AWS servers and external servers is secure.

  • How do you keep track of installed/used software/systems/services in your organisations server infr

    - by edgars
    I'm interested in any software, experience or guidelines listed that help to deal with listing installed services, their primary user (or business person that is responsible for this service), domain names, ip addresses, ports in your servers. Servers are both Windows and Linux, so licenses are also good to track with all of this information. Scale of the infrastructure in question - 20-50 servers. Currently we have no better idea as to use Excel for it.
