  • Have NetFlow show true destinations...

    - by DeliriumTremens
    Currently NetFlow is showing destination (of inbound traffic) as our outside IP rather than inside IP. Also, for all outbound traffic, it is showing the source as our firewall rather than workstations. Any ideas about how to find the true source/destination for these?

  • Access Windows from Mac via Remote Dekstop Connection using hostname

    - by stevekuo
    I'm using Snow Leopard with Remote Desktop Connection attempting to access a Windows XP machine on a home network. If I specify the Windows PC's hostname it won't connect. Only by specifying the IP address does it connect. It's the same issue when trying to ping the Windows machine - IP address works, hostname doesn't. Both machines are on the same subnet connecting with a wireless router. Is there way to get OSX to resolve the Windows PC by its hostname?

  • Setting up a subdomain on IIS7

    - by EvanGWatkins
    I have a dev server for my C# Web Application and to access the dev site I go to the server name in my browser (lfi-fsxmv06) and I can access my web application.

  • Remote access to internal machine (ssh port-forwarding)

    - by MacUsers
    I have a server (serv05) at work with a public ip, hosting two KVM guests - vtest1 & vtest2 - in two different private network - 192.168.122.0 & 192.168.100.0 - respectively, this way: [root@serv05 ~]# ip -o addr show | grep -w inet 1: lo inet 127.0.0.1/8 scope host lo 2: eth0 inet xxx.xxx.xx.197/24 brd xxx.xxx.xx.255 scope global eth0 4: virbr1 inet 192.168.100.1/24 brd 192.168.100.255 scope global virbr1 6: virbr0 inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 # [root@serv05 ~]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr1 xxx.xxx.xx.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0 169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 eth0 0.0.0.0 xxx.xxx.xx.62 0.0.0.0 UG 0 0 0 eth0 I've also setup IP FORWARDing and Masquerading this way: iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE iptables --append FORWARD --in-interface virbr0 -j ACCEPT All works up to this point. If I want to remote access vtest1 (or vtest2) first I ssh to serv05 and then from there ssh to vtest1. Is there a way to setup a port forwarding so that vtest1 can be accessed directly from the outside world? This is what I probably need to setup: external_ip (tcp port 4444) -> DNAT -> 192.168.122.50 (tcp port 22) I know it's easily do'able using a SOHO router but can't figure out how can I do that on a Linux box. Any help form you guys?? Cheers!! Update: 1 Now I've made ssh to listen to both of the ports: [root@serv05 ssh]# netstat -tulpn | grep ssh tcp 0 0 xxx.xxx.xx.197:22 0.0.0.0:* LISTEN 5092/sshd tcp 0 0 xxx.xxx.xx.197:4444 0.0.0.0:* LISTEN 5092/sshd and port 4444 is allowed in the iptables rules: [root@serv05 sysconfig]# grep 4444 iptables -A PREROUTING -i eth0 -p tcp -m tcp --dport 4444 -j DNAT --to-destination 192.168.122.50:22 -A INPUT -p tcp -m state --state NEW -m tcp --dport 4444 -j ACCEPT -A FORWARD -i eth0 -p tcp -m tcp --dport 4444 -j ACCEPT But I'm getting connection refused: maci:~ santa$ telnet serv05 4444 Trying xxx.xxx.xx.197... telnet: connect to address xxx.xxx.xx.197: Connection refused telnet: Unable to connect to remote host Any idea what's I'm still missing? Cheers!!

  • What is the correct way to distinguish services to which RADIUS request belongs?

    - by John
    If I have 1 generic RADIUS server and a number of clients (VoIP server, VPN server, WIFI access point) how to distinguish senders (NAS) of access and accounting requests? I didn't found anything helpful by reading all related RFCs, there just NAS-IP-Addess or NAS-Identifier is required, but this attributes usually represents IP address of the NAS and this address can not be used as a robust identifier, because it's often possible to fall into the case when 2 different NASes are running on the same server and this attributes can not be customized. Any ideas?

    I need to change the socket phpPgAdmin connects to in its config. // Hostname or IP address for server.

  • EC2 Instance of Wordpress not mapping URLs correctly

    - by Benjamin
    I'm using an AWS EC2 micro instance to run a wordpress blog. I've successfully mapped a subdomain to the Elastic IP for the micro instance. After a few minor changes, the URL I mapped to the Elastic IP (blog.example.com) opens up the wordpress home page but whenever I click on any of the wordpress links the domain changes to the AWS public DNS for that instance (http://ec2-123-45-678-910.compute-1.amazonaws.com/wordpress/). How do I fix the URLs so that they all follow the subdomain I have setup?

  • DNS Setting keeps changing on me

    - by Chiggins
    So on my Windows Server 2008 box, I have a DNS server installed on it. For some reason, every ten minutes or so, the Host (A) address for the computer keeps on changing to its internal private IP address. I want it to have its public address for Active Directory purposes, but it keeps changing itself back to the private IP address. Any idea as to why, and how to change it? If it makes a difference, this is an Amazon EC2 server. Thanks

  • Alias a linked Server in SQL server management studio?

    - by absentmindeduk
    Hoping someone can help - is there a way in SQL server management studio 2008 R2 that I can alias a linked SQL server? I have a server, added by IP address, to which I do not have the login credentials - however as the connection is already setup I can login ok. Issue is that, this is a dev environment, prior to a live deployment and the IP I have as a linked server needs to be 'accessible' by my stored procs under a different name, eg 'myserver' not 192.168.xxx.xxx... Any help much appreciated.

  • Routing between same networks

    - by osmandfj
    I have two different sites: NetA has a subnet 192.168.2.0/24 NetB has 192.168.1.0/24. The two sites connect each other via IPsec VPN with fortigate devices. I need to move a server with IP address 192.168.2.240 from NetA to NetB and I cannot change its IP address due to some specific reasons. My question is; if I move that server from NetA to NetB, is it possible to reach that server from NetA?

  • Do proxies really provide anonimity?

    - by user36269
    Do web proxies really provide anonimity? I mean, without someone asking for logs in a web proxy server for who/when connected, is it impossible to know who was behind that ip? I'm asking this because I heard somewhere that some technologies (like "flash") bypass personal ip information for requests or something like that. (I'm a noob in server configuration and concepts like DNS and proxies. Thanks!)

  • What all is there to know about ping while troubleshooting an internet connection?

    - by tMJ
    What all is there to know about ping and the IP address to ping while troubleshooting/diagnosing a problem in the internet connection? For example: I run the command ping 192.168.1.1 -t in the command prompt, and if there is no reply I get something is odd, but I don't understand what is and where it is. I am looking for a complete list (okay, as many as you got), of IP address to ping while troubleshooting my network connection, and an insight into what the status message returned by them implies.

    My server is installed on a guest OS on vmware. It really bugs me because I can't access it from the host OS's browser even though there is no discrepancy between /etc/hosts, /etc/sysconfig/network, httpd.conf files. Issuing ifconfig command also returns the same IP. I have also enabled netwroking in the vmware settings. And I can ping the guest OS's IP from the host. Any insights pls???
