• Running a webserver behind a firewall, is it secure?

  - by i.am.intern

  Currently we have a Linux-based firewall which NAT-ing our public IP address to give internet access to our staff's PCs and a Windows Server 2003 for internal filesharing. I want to host Redmine/SVN (a bugtracker) internally behind this firewall using a Linux server. This webserver will be accessed by our clients externally so they can post bug reports. This means that I have to open port 80 & 22 at the firewall to give access to the webserver and me to SSH it from home. However, let's say I'm using password-based SSH for the webserver and somebody cracked it. Does that mean the cracker could ping and access other servers and PCs in the network?

• Problem with PPTP VPN and internet

  - by Enriquev

  Hello, I have an internet connection the following way : Internet Modem <- FireWall(not a router, a firewall) <- PC Everything is setup so my pc has an external ip address, and my firewall takes care of blocking bad stuff. I connect by VPN to an external network, so I added a new connection using Windows Xp's "New connection wizard" (the vpn client that comes with Windows XP), it's a PPTP connection so I used all default settings. I put the PPTP server's IP, my username and password and I succesfully connected. I was able to have access to the external VPN ressources. The only problem is everytime I connect to this VPN, my computer cannot connect to the web anymore, no msn, no ping, no web. Is there anything special I should be doing?

• Apache freezing, How to detect which virtual host is getting hit?

  - by mr-euro

  I have a production server that in the last 24 hours has been hard rebooted 4 times due to freezes. Ping is fine but all other services time-out (Apache, SSHd, etc). I have now diagnosed it to Apache running out of memory due to an exorbitant amount of child processes forking suddenly within seconds of starting Apache. Stopping Apache just after rebooting keeps the server stable again. My two questions are: Is there a way to detect which of the vhosts is being suddenly hammered without looking into each vhost's access log one by one? Is there a way to quickly enable/disable vhosts without commenting (#) them all out in httpd.conf?

• Installed IE8 & SP3 on XP now I can't HTTPS from any browser.

  - by Kevin

  The computer is Windows XP Professional SP3 with IE8. On the Tools Options Connections the "Settings" is GRAYED OUT (I am an admin on the machine) Any browsing of https:// addresses results in IE displaying the following: "this program cannot display the web page" After installing an alternate browser and trying the same https:// address I get a similar error message. I have tried using Compatibility View Settings to for all web pages and this has no effect on the problem. HTTP addresses work fine, I can PING sites such as google.com without issue. Question: What could be preventing me from getting at the settings to check to see if I'm using a proxy? What else could be preventing HTTPS access?

• Nagios dropping ICMP packets

  - by Ankh2054

  I am running a Nagios server on vmware 4.0 and every now and again during the day it alerts that some of servers cannot be reached via ICMP, clearly staging that a certain percentage of packets send are lost. This does not happen to all servers. I know the servers are actually up, because I have done a parallel test from another windows box, just using simple ping and no packets were lost. I also now from the way we monitor out switch that no packets were lost on those particular ports. Could anyone suggest a way to troubelshoot this further ? AT present this points to the nagios server itself loosing packets. thanks

• Azure VM : Connection refused by host

  - by Simon Kérouack

  I recently stopped a subscription with 14 VMs in it and restarted it a few days later. Now all my VMs are working just fine at the exception of 6 used for MongoDB. They respond to ping and so they show as online in the azure dashboard but they do not answer to anything else. I tried (from different locations, in and out of the azure cloud) ssh : connect to host * port *: Connection refused telnet : Unable to connect to remote host: Connection refused mongo : exception: connect failed The ports for ssh and mongo are opened in azure. I tried restarting the VMs a few times trough the azure dashboard, they seem to restart successfully but still refuse all connections. I already looked for similar issues and the best solutions I found was to wait... the issue has been happening for 7 days and waiting is no more an option.

• Name of my sql server instance from outside the network

  - by Michel

  Hi, normally i connect to my sql server instance from my local computer, and then the server name to connect to is the name of my laptop. So i can connect to server instance 'MichelLaptop' But now i'm trying to connect to my server from outside my network, and the first thing i wonder is: what is the name of the instance? i've made a redirect to my local machine in the DNS of my domain, so i said (this is not the real data) testsql.mydomain.com goes to 190.191.192.193 and when i ping testsql.mydomain.com, i get a response from 190.191.192.193 But what then is the server name?

• OpenVPN (HideMyAss) client on Ubuntu: Route only HTTP traffic

  - by Andersmith

  I want to use HideMyAss VPN (hidemyass.com) on Ubuntu Linux to route only HTTP (ports 80 & 443) traffic to the HideMyAss VPN server, and leave all the other traffic (MySQL, SSH, etc.) alone. I'm running Ubuntu on AWS EC2 instances. The problem is that when I try and run the default HMA script, I suddenly can't SSH into the Ubuntu instance anymore and have to reboot it from the AWS console. I suspect the Ubuntu instance will also have trouble connecting to the RDS MySQL database, but haven't confirmed it. HMA uses OpenVPN like this: sudo openvpn client.cfg The client configuration file (client.cfg) looks like this: ############################################## # Sample client-side OpenVPN 2.0 config file # # for connecting to multi-client server. # # # # This configuration can be used by multiple # # clients, however each client should have # # its own cert and key files. # # # # On Windows, you might want to rename this # # file so it has a .ovpn extension # ############################################## # Specify that we are a client and that we # will be pulling certain config file directives # from the server. client auth-user-pass #management-query-passwords #management-hold # Disable management port for debugging port issues #management 127.0.0.1 13010 ping 5 ping-exit 30 # Use the same setting as you are using on # the server. # On most systems, the VPN will not function # unless you partially or fully disable # the firewall for the TUN/TAP interface. #;dev tap dev tun # Windows needs the TAP-Win32 adapter name # from the Network Connections panel # if you have more than one.

• private subnet nat (openvpn / racoon)

  - by Jonas Schnelli

  I have a openvpn subnet 10.8.0.0/24 running one server and one client (laptop). openvpn works fine. Browsing the web over openvpn from the laptop works also fine. Now on the server there is a private subnet with 10.7.8.128/28. The subnet is set up with racoon (IPSEC s2s vpn). The s2s vpn allows me to access the subnet 10.3.5.0/24 at the other s2s vpn end. Works all fine when I'm connected with ssh to my server. From my laptop i can ping 10.7.8.129 (the servers ipsec local ip) but i cannot reach the net 10.3.5.0/24. I tried to add a static route on my laptop 10.3.5.0/24 over gw 10.7.8.129 with no success. Any ideas how i do setup the nat / routing? Thanks

  - by Gk

  Here is my diagram http://imageshack.us/photo/my-images/263/vpnt.png/ Server has two NIC: One connect to Internet, one connect to internal network. RAS service is configured with static IP pool on the same subnet of internal network (10.10.0.x). The problem is when a client connect to server, client can connect to server(10.10.0.10), but cannot connect to another host locate in internal network (10.10.0.11) even cannot ping to 10.10.0.50. RAS configured with IP routing enabled, client connect with options: Use default gateway on remote network. I'm messed up and can not figure out what wrong. Please help me T_T. TIA, giobuon

• How do I get the machine name from an IP via Multicast DNS?

  - by Adam

  I have a list of IP addresses on a network, and most of them support multicast DNS. I'd like to be able to resolve the server name instead of just having the IP address. ping computer.local 64 bytes from 192.168.0.52: icmp_seq=1 ttl=64 time=5.510 ms 64 bytes from 192.168.0.52: icmp_seq=2 ttl=64 time=5.396 ms 64 bytes from 192.168.0.52: icmp_seq=3 ttl=64 time=5.273 ms Works, but I'd like to be able to determine that name from the IP. Also the devices don't necessarily broadcast any services, but definitely do support mDNS broadcast. So looking through services won't work.

  - by Kossel

  I have a small office network basically like below, there are more router/pc connected in S1. As you can see, the router is doing job of DHCP, DNS. but now I wish to add a Linux server between R1 and S1, So I can monitor the network traffic and do other more advance server admin stuff. the whole office network is 192.168.1.x and people are using their computer everyday. What network configuration should the new Linux server have (both interfaces) in order to minimize the changes need in the network? tried to change R1 ip to 192.168.100.1 them add the server with FE0/0 192.168.100.1 and FE0/1 192.168.1.1 but looks cannot ping the original Router..

• WinXP workgroup, 3 routers 3 computers

  - by Silvera

  I have 3 computers with WinXP x86, and 3 Cisco 1800 series routers. I'm trying to create a workgroup so that the 3 computers can share files with eachother. They can ping eachother (without any internet connection), and the routers setup is correctly configured (with interfaces, ip adresses, and ports). But none of the computers can see eachother, even though they are on the same network. My first question would be - can it be done the way it is currently configured - and, if yes, how, or can anyone point me in the right direction?

• Cant access EC2 hosted website

  - by Himanshu Page

  For some reason, I am unable to access our website www.doccaster.com (Bad request nginx). We are hosted on amazon EC2 with elastic ip associated to it. The weird part is a) I can access it through the public dns url http://ec2-184-73-195-180.compute-1.amazonaws.com b) My co founder who is located in another city can access it via www.doccaster.com. I observed that my instance was failing reachability check, so I launched a new one and assigned it the the elastic ip. I tried to ping the ip address 184.73.195.180 from my machine but no success. Any help will be really appreciated. More details I ran the following command on my server netstat -lntp | grep -E 'apache|httpd' and it displays :::80 for httpd . Is this accurate ? Should it be 0:0:0:80 ? or doesnt matter?

• Log into AD account through Command Line

  - by CranialPain

  Our SBS2003 server likes to lose connection every so often. This appears to 'kick' everyone out, so that no-one can access the server or its shared folders without a log off log in. It usually brings up an error message stating that Windows 7 (on the client machines) cannot find the server, even though its ping-able. Is there a way to login through the command line so I can just write a batch file and have the users double-click it and enter their credentials instead of closing down programs and logging out/in over and over?

• Internet wireless connected with limited access, windows vista

  - by Wawa wiya

  Hello I had some malware in my computer so I did a bit of manual work to remove it including resetting TCP/IP. Now the malware is gone. I can see my home wireless network and I can get connected to it but when connected I get the Internet wireless connected with limited access message. When I go to the IE I cannot browse. When I tried to ping 192.168.1.1 I got an Error Code 1231 Unconnected Network Problem. I have deactivated my Windows firewall as I thought it could be hyperactive security. Still no luck. I have Norton but it is not active, I have also Avast and AVG installed but they are not active. Any ideas?

• Jumbo Frames on DIR-655

  - by Spookyone

  I am trying to set up jumbo frames on my gigabit home LAN but no luck so far. My setup is: D-Link DIR-655 router, HW Revision A3, Firmware 1.21 EU Synology DS107+, Firmware 3.0-1337 Laptop w/ Win7 x64, external PCIx NIC managed by "Generic Marvel Yukon 88E8053 based Ethernet Controller" The router is supposed to support jumbo frames but doesn't feature any relevant setting. I set the Jumbo Packet value to 9000 on both the NIC and the Synobox but it doesn't work, ping -f -l 8972 says "Packet needs to be fragmented but DF set". Is there any other setting I overlooked, the DIR-655 doesn't actually support jumbo frames, or what else could be the problem?

• rsync server side limit bandwidth/connection

  - by c2h2

  In a VOIP application, I have upto 3000 clients rsync audio files from there linux server in a daily, server is placed at a data center (10Mbps in/out bound), the server works as a VOIP sip server running FreeSWITCH (low ping latency should be ensured.) Therefore I would like to have server side control of rsync which controls: Limit total outbound bandwidth. Limit total number of connections. (Reject clients while at max number of connection and let it retry after a specific time frame.) OPTIONAL: list/kill individual connections. Normally I would use ssh + rsync + pem_keys with some extra options, but above requirements are not feasible by simple command lines. Can anyone point me some direction. or show some scripts/tools? I would also probably integrate them and release on github. Thanks!

I found 2 . 1st datcenter is in San Francisco, CA . 2nd data center is in Newyork. Then I do the ping from each datacenter to the my partner's IP. 1st datcenter's result: 75ms 2nd datacenter's result: 2ms I 've done multiple time, 2nd datacenter always give better result. Now my question is: Isn't the 1st datacenter suppose to give better result, since their location are closer ? How come the result produce different, what is the accurate way to check latency ?

• Automatically reboot Windows8 if no internet activity [migrated]

  - by Patrick

  I have a media server located in a very inconvenient part of my house. Occasionally I will have to reset my router or it will reset itself. The issue is the PC loses connectivity for some reason, and I am forced to walk outside, around the house, into the basement, over a bunch of toys and weights and boxes, to push a button to reboot it. I would love to have it check itself every 5-10 minutes and auto reboot if it is unable to ping a given address/IP. Any ideas how to accomplish this?

• dig gets the right result from DNS server, but name still fails to resolve

  - by EMiller

  Under what conditions would the following occur? From a given OSX machine on an internal network: $~ cat /etc/resolv.conf nameserver 10.102.120.7 nameserver 10.102.120.2 From the same machine: $~ dig @10.102.120.7 in.local <snip> ... ;; QUESTION SECTION: ;in.local. IN A ;; ANSWER SECTION: in.local. 43200 IN A 10.102.123.30 <snip> ... And yet, this workstation cannot ping in.local, nor load pages hosted by apache on that machine. 10.102.123.30 is definitley up (2 OSX machines I know fail to resolve in.local - but other machines on the network can). I have also checked their /etc/hosts to see if anything there might interfere... Not sure what else to check...

• VirtualBox cloned Ubuntu Server network error

  - by Luke

  I run a number of virtual servers on my network and I want to be able to easily clone base installations of Ubuntu Server. I use the VBoxManage command to clone the actual hard disk and I then create a new profile for my VM and copy over the settings of the original VM. However, when I boot into the cloned VM, there seems to be a network problem. When I issue a PING I get the message "Network unreachable". I traced it down to the fact that the virtual network card of the cloned VM has a different MAC address then the original VM. When I copy the MAC address the clone seems to work fine. How can I have the cloned VM have it's own MAC address?
