  • Access to NTP via IP which doesn't change often

    - by faulty
    I'm trying to sync the clock of our production server located in a data center with pool.ntp.org. For security reason, our servers has no internet access unless we requested to open specific ip/port explicitly. I worked out a list of IPs based on 0.asia.ntp.org 1.asia.ntp.org 2.asia.ntp.org 3.asia.ntp.org Not realizing ntp.org is using round robin DNS and the servers being voluntary, they changes from time to time. In fact the IP I've got from 3.asia.ntp.org last month is no longer working now. I'm wondering if there's a publicly known NTP server that doesn't change as often or if there's a way to go around this without having to request an update to the firewall on a monthly basis. I believe many admin is facing the same issue here.

  • How to configure LAN IP Filter on Huawei E586 UMTS Modem

    - by Mose
    I need to prevent clients of an Huawei E586 UMTS to WiFi modem from downloading much data from specific servers eg. Windows update or OSX update. On the config page of the device there's an "LAN IP Filter" which seems pretty good but I can't figure out the right settings. The mask looks like this: The help pages states the following: My problem with this is, I want some wildcard for the local ip and port. In my opinion the help page can not be correct by "lan port: enter 80" because the source port is normally dynamic. I tried to set it up like stated there but as expected it doesn't work. As wildcards I tried * and "ALL" but nothing worked as it prevents me from saving settings with an "wrong value" error. Any suggestions? Thanks in advance!

  • How to pass an IP address to inet_addr?

    - by November
    I can't seem to pass an IP address to inet_addr. I have gone through the debug but I still can't figure out why this won't work. printf("Server IP\nIP:"); scanf("%s",cmdPtr); //Bind socket address.sin_family = AF_INET; address.sin_addr.s_addr = inet_addr(&cmdPtr); address.sin_port = htonl(SERVER_PORT); lenC = sizeof(address); if (connect(sdC, (struct sockaddr *) &address , lenC) < 0) { perror("Could not bind Socket\n"); return -1; }

  • Remote connection IP to use

    - by petwho
    I have two laptops that both run on ubuntu and installed ssh server and ssh client on them. One is usually on my desk at home and one I usually bring to my company. When I'm at home I can easily ssh to one from the other by typing this command (to login to the other laptop whose IP address is: 192.168.0.105) : ssh -p 22 [email protected] However, When I'm at my company, I try to type the same command and ofcourse it doesn't work. I understand that when at home I'm on LAN network, that my laptops actually using my ISP's address which differ from 192.168.0.107 asummed 203.113.131.1. So could you tell me what IP that ssh shoud use for my laptop (at work) to connet to my computer at home? Thank you.

  • Can't ping devices by IP address for devices allocated IPs by DHCP

    - by GiddyUpHorsey
    I have a home network with a Trendnet wireless router and a Windows Domain. The Domain Controller/DNS server is a Windows 2000 Server and is configured to forward queries to DNS servers provided by the ISP. The router provides DHCP and is configured with the Windows 2000 Server as the DNS server. The network has been set up for a couple of years and usually works fine. When I connect iPhones to the network over WiFi, the router can ping the iPhones through its browser based admin interface, but Windows machines that are part of the Windows Domain cannot. A laptop was connected to the network over WiFi that wasn't joined to the domain and it could see the iPhones. The router UI shows that the laptop has a reserved IP allocated via DHCP. All machines either have a static or DHCP allocated IP on the 192.168.0.* subnet. Router - 192.168.0.1 - Static - Wired Windows Domain Controller - 192.168.0.8 - Static - Virtual Windows 7 Workstation - 192.168.0.200 - DHCP Auto - Wired VMWare ESXi Host - 192.168.0.201 - Static? - Wired iPhone 1 - 192.168.0.202 - DHCP Auto - WiFi iPhone 2 - 192.168.0.203 - DHCP Auto - WiFi Windows Vista Laptop - 192.168.0.204 - DHCP Reserved - WiFi Using the Windows 7 machine (200), I try to ping each machine and the only DHCP machine that responds is itself. The other DHCP machines fail with Reply from 192.168.0.200: Destination host unreachable.. Using nslookup fails with *** domain.controller.name can't find 192.168.0.203: Non-existent domain. Using the Windows 2000 Domain Controller (8), I try to ping each machine and the only DHCP machine that responds is the Windows 7 machine (200). Pinging the other DHCP machines fails with Request timed out.. Using nslookup also fails with *** domain.controller.name can't find 192.168.0.203: Non-existent domain. Using the iPhone 2 (203), I try to ping (Network Ping Lite) the machines with static IP addresses and that works fine. When I try to ping the Windows 7 machine (200) it is unable to get a response. How do I configure the DNS server/Windows Domain/Router properly so that the Windows Domain machines can see the IPs allocated via DHCP?

  • Assign two static IP addresses to one mac address

    - by Timo Ylikännö
    Can Isc-dhcp-server give two static ip addresses to one mac address? I have several home terminals in my network. Each terminal have two interfaces. One for public traffic and one for a management traffic. Both interfaces have same mac address. DHCP server can detect interfaces via dhcp option field and dhcp class declarations. Every terminal have to have static ip address instead of dynamic address. With dynamic address and dynamic pools this would be an easy task. Or is there any dhcp server that can do this?

  • Apache server in raspberry PI not visible from outside( public IP)

    - by Kronos
    I have made a fresh install of Arch Linux ARM into a Raspberry PI and I mounted there a LAMP, all fresh. I have another Arch(x86) in my laptop with Apache also there, and as far as I know, two web servers cannot run in the same network segment so, the problem is as follows. I my laptop, having Apache running, if I enter via the public ip of my network everything turns ok and I can see my website but, (obviously turning this server down) if I enter from the public IP with the Apache running in the raspberry pi( yes, only that Apache running) i cannot see my website in there. Also, if I access via local network it is a normal success, I can see my website. So, I can enter my raspberry website only via local but in my other web server i can enter it via local and public. I have the same conf files in both of them so what is the difference? I was planning in making the rpi as a development server. Thanks in advance

  • Does IP helper forward subnet broadcasts?

    - by Eamon
    Hi, I have a device on a VLAN that uses UDP subnet broadcasts to advertise its presence to similar devices. This works fine on a single VLAN, but now I need to allow it to communicate with similar devices on a second VLAN. I thought of using the IP helper command in the router, but I am wondering if that only forwards global broadcasts (255.255.255.255)? My device sends out a subnet broadcast (e.g. 192.168.6.255) Will IP helper change the destination address to the target subnet (e.g. 192.168.7.255)? Eamon

  • DHCPD Offering ip address on wrong subnet

    - by Logan
    I just recently added a new subnet for our wireless network to our DHCP configuration for the 192.168.254.0 subnet. Most of the time when wireless clients connect it works just fine. However, sometimes on seemingly random occasions the DHCP server will send out a DHCPOFFER with an IP address on the wrong subnet. Example: dhcpd: DHCPDISCOVER from MACADDRESS (ThinkBook2) via 192.168.254.1 dhcpd: DHCPOFFER on 192.168.22.236 to MACADDRESS (ThinkBook2) via 192.168.254.1 Here is the subnet configuration in dhcpd.conf: subnet 192.168.254.0 netmask 255.255.255.0 { option routers 192.168.254.1; range 192.168.254.34 192.168.254.254; default-lease-time 14400; authoritative; } How can I make sure the server always sends out an IP address on the right subnet?

  • Gathering IP's from a complicated log

    - by Harry
    I have a question regarding the use of some more advanced grep, awk, sed. I have a log file, for a proprietary MTA, that contains IP's in a string, delimited by [redacted]^~x.x.x.x^[redacted]. So far all of my grepping, awking, and sedding hasn't gotten me very far. This log file has 331520 lines in it. My goal was to simply grep out the ip's, then do a for loop with sed, to sed 's/$i/redacted'. I'm including a sample of one of the log entries. If you all have any idea, I would be greatly appreciative.

  • Configure IIS to rewrite IP Address to Site Name

    - by Bath Man
    So i've started my first web site from home, and I'm trying to get it up and running and google crawlable and the like, but I can't seem to figure out how to have my site name returned in the address bar instead of my IP address. I've purchased a domain name for my site on Godaddy and then set it to redirect to my site. When you type in the domain name, you get redirected to http://0.0.0.0/default.aspx (not my real IP obviously), and that stays in the user's address bar. In order to fix that temporarily, I've set up masking on Go Daddy which keeps the URL in the address bar, but just shows my website in a frame. This is fine for users visiting the site, however any kind of automated robot such as GoogleBot cannot discover my content because of the frame. I've looked into ISAPI filters and server-site-rewriting, and the like... but I just can't quite figure out how to do what I need it to do. Any simple suggestions or links would be appreciated.

  • MySQL Workbench sends computer name with login not IP

    - by Android Addict
    I am attempting to connect MySQLWorkbench to a remote MySQL Server. The server has granted access to user@IPAddress However, when I try to connect MySQLWorkbench, it sends user@computername instead. How do I configure the connection to use the IP address instead in MySQLWorkbench? Reference: The remote server is on the local network, so I need to use the local IP address assigned to my client. EDIT What I have tried so far: from the server: mysql -u user@IPAddress -p --host=(ServerIPAddress) Returns: mysql> So that tells me the user account is operational. Furthermore, I confirmed it exists using: select user from mysql.user; returning a table of all users, of which the user I am using is present. I have also opened the port 3306: sbin/iptables -A INPUT -i eth0 -s clientIPAddress -p tcp --destination-port3306 -j ACCEPT Still I encounter Access Denied

  • Weird DNS bug - external server resolves to internal IP

    - by emilecantin
    I have a server that is hosted by my university. I have root access, but no control over network setup, firewall, etc. This server's DNS resolves to an internal IP here on campus (10.x.x.x), and an external IP outside campus. I also have a few servers hosted at Amazon, and they mostly work well. However, one of them started to resolve the university server by its internal IP address. This causes problems, as 10.x.x.x on Amazon EC2 is someone else. I have connected to the Amazon server with SSH agent forwarding a few times in the past, to access a Git repository on the university server. Any idea what could cause this?

  • Proxmox 31 + KVM routing + IP subnet + csf

    - by KeyJey
    We have proxmox 3.1 server in netzner with routuing network and IP subnet block. We want to implement csf firewall without interfering the traffic of the KVM VMs, what would be the easiest way? We readed that we should add this lines to /etc/csf/csfpost.sh: iptables -A FORWARD -d 144.76.223.155 -j ACCEPT iptables -A FORWARD -d 144.76.223.156 -j ACCEPT iptables -A FORWARD -d 144.76.223.157 -j ACCEPT iptables -A FORWARD -d 144.76.223.158 -j ACCEPT iptables -A FORWARD -d 144.76.223.159 -j ACCEPT iptables -A FORWARD -d 144.99.183.323 -j ACCEPT But when we enable csf the ping breaks, this is the network config (IPs are modified): auto lo iface lo inet loopback # device: eth0 auto eth0 iface eth0 inet static address 144.76.166.100 netmask 255.255.255.255 pointopoint 144.76.183.97 gateway 144.76.183.97 # for single IPs auto vmbr0 iface vmbr0 inet static address 144.76.166.100 netmask 255.255.255.255 bridge_ports none bridge_stp off bridge_fd 0 up ip route add 144.99.183.323/32 dev vmbr0 # for a subnet auto vmbr1 iface vmbr1 inet static address 144.76.166.100 netmask 255.255.255.248 bridge_ports none bridge_stp off bridge_fd 0 Thanks in advanced ! :)

  • VPN Error 868 when connecting even if using IP address

    - by Fr33dan
    I am trying to connect to a public VPN from VPNGate. However when I attempt to connect to a VPN from the list using MS-SSTP protocol I get the following error: Error 868: The remote connection was not made because the name of the remote access server did not resolve. If I open a command prompt and ping the address in question it resolves to the IP shown on the listing. If I configure the VPN using that IP address directly I still receive the error even though the name no longer needs to resolve. This was working yesterday but it seems the VPN I was using has been removed from the list. What is happening and how can I fix it?

  • IIS Seems to Forward Domain/IP to Domain Controller

    - by asinc
    We have a server (Server 1) with Win 2008 that is accessible by RDP and also is set as the primary DNS IP for a domain (example.com). This server is on the same network as an SBS 2008 server (Server 2) which is the domain controller and internal Dns server. Web requests going to example.com with IP of Server 1 are being passed to Server 2 and served up by IIS from Server 2. What causes this to happen? Is there a safe way to have Server 1 IIS handle the web requests which was our expected outcome? Example: DNS entry on ISP: example.com = 111.111.111.111 Server 1 = 111.111.111.111 Server 2 = 111.111.111.112 Web user goes to example.com in browser, and the page is actually returned from 111.111.111.112?

  • How to setup heartbeat for IP fail over on SSH failure

    I wonder if anyone can help me, I am trying to setup heartbeat on a redhat 5 to failover an IP address when ssh stops responding on a server. So basically you ssh to a VIP and then get put through which ever server has the floating ip. 192.168.0.100 | | /------------------------\ | /------------------------\ | Server 01 | | | Server 02 | | eth0 - 192.168.0.1 |-----/ | eth0 - 192.168.0.2 | | eth0:0 - 192.168.0.100 | | eth0:0 - down | \------------------------/ \------------------------/ if ssh stops responding i want eth0:0 to be brought up on the second machine to allow ssh connections to carry on being served. I have tried to follow some documents I have found online so here is my current configuration: ha.cf bcast eth0 keepalive 2 warntime 10 deadtime 30 initdead 120 udpport 694 auto_failback off node vm-bal01 node vm-bal02 debugfile /var/log/ha-debug logfile /var/log/ha-log authkeys auth 1 1 sha1 sshhhsecret1234 haresources server01 192.168.0.100/24/eth0:0/192.168.0.255 Hope someone can help as this is driving me nuts...

  • Latency in TCP/IP-over-Ethernet networks

    - by aix
    What resources (books, Web pages etc) would you recommend that: explain the causes of latency in TCP/IP-over-Ethernet networks; mention tools for looking out for things that cause latency (e.g. certain entries in netstat -s); suggest ways to tweak the Linux TCP stack to reduce TCP latency (Nagle, socket buffers etc). The closest I am aware of is this document, but it's rather brief. Alternatively, you're welcome to answer the above questions directly. edit To be clear, the question isn't just about "abnormal" latency, but about latency in general. Additionally, it is specifically about TCP/IP-over-Ethernet and not about other protocols (even if they have better latency characteristics.)

  • Metro Apps on Win 8 aren't working with static ip behind auth proxy

    - by Kamal
    In Windows 8 Professional, Metro Apps and Windows Update do not work on static IP settings behind authenticated proxy server. They work on DHCP on the same proxy settings. (We have DHCP for wifi and static IP for LAN, both using the same proxy server). IE, Chrome and other desktop apps work nicely on both. Metro apps worked on an auth proxy (DHCP only), when I changed their proxy settings from the 'edit group policy' option. (StartSettingsEdit Group PolicyComputer ConfigurationAdministrative TemplatesNetwork IsolationInternet Proxy for Apps) Can this be fixed?

  • Get sessions' remote IP from Teamviewer log file

    - by etuardu
    I'd like to know who has logged in to my machine and when. I have two TeamViewer log files: Connections_incoming.txt and TeamViewer7_Logfile.log. The first one is quite plain and lists, as its name says, the incoming connections to the machine, reporting the local name of the remote host, login time, logout time, and some ids. e.g.: 173274362 MYLAPTOP 20-02-2012 17:32:16 20-02-2012 17:50:42 Master RemoteControl {C5AAE483-ED0B-54B8-9235-7AE597CAD342} This is almost all what I need, but unfortunately no remote IP address is reported here, so I checked for IPs in TeamViewer7_Logfile.log but it is really messy. It indeed contains some IP addresses but I can't understand which one is bound with the items in the first log file. Is there a way to interpolate the two logs to get what I need? Should I search the second file for some particular text? What do you suggest?

  • Blocking a country (mass iP Ranges), best practice for the actual block

    - by kwiksand
    Hi all, This question has obviously been asked many times in many different forms, but I can't find an actual answer to the specific plan I've got. We run a popular European Commercial deals site, and are getting a large amount of incoming registrations/traffic from countries who cannot even take part in the deals we offer (and many of the retailers aren't even known outside Western Europe). I've identified the problem area to block a lot of this traffic, but (as expected) there are thousands of ip ranges required. My question now (finally!). On a test server, I created a script to block each range within iptables, but the amount of time it took to add the rules was large, and then iptables was unresponsive after this (especially when attempting a iptables -L). What is the most efficient way of blocking large numbers of ip ranges: iptables? Or a plugin where I can preload them efficiantly? hosts.deny? .htaccess (nasty as I'd be running it in apache on every load balanced web server)? Cheers
