  • Can I set up a different method of authentication on Nagios?

    - by cwd
    Nagios is a wonderful too for monitoring servers. Their web interface is not bad, either. However I am not crazy about using the HTTP Authentication that comes standard. Is there a way to use another method of authentication? (and I don't mean restricting access by IP address in the .htaccess file) Something with a form-based login would be wonderful, but perhaps there is no such thing. I'm hoping you guys have found something I haven't.

    - by ssl
    Hi, I have a Linux machine which connected to an Active Directory on Windows server. I configured the NIC to get an IP from the DHCP (from the windows server) however, when I try to get nslookup on the Linux side it doesn't work (connection timeout), but on the same machine when I load windows and do nslookup it works. what can be wrong with my Linux configuration or Windows DNS configuration? note: I've configured my DNS to nonsecure and secure connections. 10x!

  • Looking for a solid redirection infrastructre

    - by isoman
    We have critical servers (webservers and databases) that are fully replicated, except for the reverse proxy that we use to hide the internal stuff. This proxy is acting like a router that filters and redirects traffic to the main server and switch for failover if the main one is down. We want to find an alternative to this proxy because one single entry point is not enough. Is there any company that has a solid and redundant infrastructure that offers redirection to an IP and allows quick switching to another one?

  • Cisco Unifies Communications Manager 7.0 - Installing Extension Mobility

    - by Lance
    I've setup extension mobility to the best of my ability, however, it its perplexing me... From the materials I've been reading I have established I need to have the following URL in place: http://IP/emapp/EmAppServlet?device=#DEVICENAME# If I try and browse to this in a web browser I can a blankHTML page. When my registered phone (CIPC) presses Services - Extension Mobility, it just sits there / delivers a blank page. I figure this isn't coincidence... Any ideas?

  • How to discover which name/address connections from one network to another uses?

    - by Jader Dias

But connections to another remote network it appears with a different origin. How to discover which name/ip it is using? I tried tcpdump and netstat in the destination but it is difficult to find my connection among billions of others. In my case the destination is a Windows Server 2003

  • Setup wiped Polycom phone without SIP server

    - by Justin
    I'm troubleshooting a Polycom SoundPoint IP 550. I have wiped the hard disk of the phone (via a menu option) and now it's stuck in a reboot cycle. Apparently the only way to setup the firmware of the phone is to use a boot server. Does anyone know another way to setup the phone/firmware?

  • Is there a way to detect which port on an ethernet switch a device is connected to?

    - by banno
    Since the wall jack is typically always connected to the same port on the switch I would like to be able to know which device is connected at a specific location. In my case I am talking about printers. I have code to go out on the network and find the IP Address of all of my printers, but would like to be able to update a server based on a printer being swapped out of a location for maintenance or repair. Is there a method for determining a port connection?

  • nginx + apache subdomain redirection fault

    - by webwolf
    i really need your advice folks since i'm experiencing some troubles with nginx & apache2 subdomains configs first of all, there's a site (say, site.com) and two subdomains (links.site.com and shop.site.com) whose files are physically located at the same level of FS hierarchy as the site.com itself my hoster has configured both apache and nginx by my request, but it still doesn't work as it used to both of subdomains point to the main page of site.com for some unknown and implicit (for me) reason :( my assumption is that's happen because site.com record is placed first in both configs?!.. please help me solve this out!

  • ping preload is not permitted, what could be the reason?

    - by Brogrammer
    I am trying to ping one of my local host and checking CPU process to see how "Ping of death" attack behaves. I tried to ping my other PC which is in local network with 192.168.44.2 IP Address. I tried this, ping -l 5000 192.168.44.2 and I got error like this, ping: -l flag: Operation not permitted I am on MacOSX Lion. How can I remove this flag so machine can let me ping with preload? Thanks for any direction!

  • What does it mean - to get billed to the 95th percentile at $x.xx per meg?

    - by timofey
    I got a quote from a colo, saying "I could do 3U, the power and 20 megs burstable to 100 for $250 a month with each additional meg billed to the 95th percentile at 6.50 per meg..so you would have he ability to burst if you needed it but not pay for the full 24/7 amount of the IP." I'm assuming it means - 20Mbits unmetered, anything above is billed on the 95th percentile at the rate of $6.50/Mbit. Am I right? And how do you measure the $x.xx per meg, at 95th percentile?

  • Ubuntu Server on live Internet

    - by vaibhav
    I just installed Ubuntu Server 12.04 in an office machine with openSSH, DNS and LAMP Server. I also made the IP static and I can access the server in my office premises easily, but when I try to access my server from my home it is not working. I know I have to make some changes and need to install some firewall (I had just gone through with a couple of posts) but I guess an expert advise will save my time here.

  • Configure server on network to analyze traffic

    - by Strajan Sebastian
    I have the following network: http://i.stack.imgur.com/rapkH.jpg I want to send all the traffic from the devices that connect to the 192.168.0.1 router to the 192.168.10.1 router(and eventually to the Internet), by passing through the server and an additional router. Almost 2 days have passed and I can't figure what is wrong. While searching on the Internet for some similar configuration I found some articles that are somehow related to my needs, but the proposed solutions don't seem to work for me. This is a similar article: iptables forwarding between two interface I done the following steps for the configuration process: Set static IP address 192.168.1.90 for the eth0 on the server from the 192.168.1.1 router Set static IP address 192.168.0.90 for the eth1 on the server from the 192.168.0.1 router Forwarded all the traffic from 192.168.0.1 router to the server on eth1 interface witch seems to be working. The router firmware has some option to redirect all the traffic from all the ports to a specified address. Added the following rules on the server(Only the following, there aren't any additional rules): iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT I also tried changing iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT into iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT but still is not working. After adding the following to enable the packet forwarding for the server that is running CentOS: echo 1 /proc/sys/net/ipv4/ip_forward sysctl -w net.ipv4.ip_forward = 1 After a server restart and extra an extra check to see that all the configuration from above are still available I tried to see again if I can ping from a computer connected to 192.168.0.1/24 LAN the router from 192.168.1.1 but it didn't worked. The server has tshark(console wireshark) installed and I found that while sending a ping from a computer connected to 192.168.0.1 router to 192.168.1.1 the 192.168.0.90(eth1) receives the ping but it doesn't forward it to the eth0 interface as the rule tells: iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT and don't now why this is happening. Questions: The iptables seem that don't work as I am expecting. Is there a need to add in the NAT table from iptables rules to redirect the traffic to the proper location, or is something else wrong with what I've done? I want to use tshark to view the traffic on the server because I think that is the best at doing this. Do you know something better that tshark to capture the traffic and maybe analyze it?

  • Does NAT change the source MAC address?

    - by user44073
    I'm trying to secure my home network but don't really need the complexity of a VPN so I'm trying to figure out other options. I'd like to allow my iPhone remote access to my home servers but I can't depend on the IP address because it changes quite often (due to the 3G network, etc). Can I filter incoming connections on my router (pfsense) by MAC address or does NAT change the source as it's passing through the different routers on the internet?

  • How to route all network traffic for vlan through a proxy server on SRX

    - by user112570
    I'm trying configure an SRX router to automatically forward all traffic through a proxy server i have in the USA. I have created a separate vlan and configured the proxy but not sure how i can route all traffic through this. The aim of this task is create a test network which makes users appear in the location of the proxy server. (with the external ip address of the proxy) Is this possible and how should i do this. Am i approaching this the right way? Thanks
