I've installed Ubuntu Server 10.10 with two network cards. One for external, and one internal.My problem is that as soon as i activate eth1 (external), i can't access the server from the internal network (eth0)
With these settings i can't reach the internal network from inside.If i disable the gateway on eth1 and enable the gateway on eth0, it works.
I have a problem configuring my PostGreSQL server for internal network access.
I want to be able to access my postgre server from 192.168.1.10
It works when I set listen_address to *, but if I input 192.168.1.10, or any other IP address, I always get:
Quote:
WARNING: could not create listen socket for "192.168.1.10"

I have a desktop computer running OpenSUSE 11.2 with two network cards installed. I would like to use both cards for connecting to the internet using different networks. The setting would be the following: eth0 is the main (default) card, almost all programs should use this NIC for connecting to the internet. eth1 is used only by a few programs, which have setting for selecting which network interface to use. The two NIC's are connected to different networks, so the IP address of the NIC's, the related subnet masks and gateways are also different.
Saying short, I would like to have the two NIC's as they would be in two separate computers. I can set the IP address and subnet mask of the NIC's. The main problem is that I can only declare one gateway. How can i setup this? I do not use network manager, I configure network cards using yast, but if needed I can of course use ifconfig directly.
I use a network-connected HP printer through hplip and cupsI'm trying to discover how to access the media card ports that are built-in on the printer.

I am in the process of setting up my own Linux gateway/firewall using two nics eth0(external network) and eth1(internal network). The Linux gateway hands out ip addresses using dhcp3-server, and uses iptables to route the traffic correctly. Clients are able to connect and access the internet...everything is working great, HOWEVER I can't access my apache virtual hosts websites from the internal network? They work just fine if i access them from the outside world
I can type ip of the web server, 192.168.0.201 and it shows the first virtual host listed in my /sites-enables/000-default folder. but i can't use any DNS entries. I don't have any internal DNS servers running. This doesn't makes sense, because if i replace the linux firewall/router with my normal linksys wrt54G router it works just fine.
I have a Proliant 7000 with 4 interfaces across 2 cards - 3 intel 10/100Tx and 1 intel 100FX. During install it detected the 3 tx interfaces - but couldnt see the network - post install the network devices were no longer there, their devices missing from /dev/.
Neither google nor a forum search have been particularly edifying, is this a known issue with any cards? If so is there a known fix? ifconfig gives me information for loopback only as expected.
I currently have an Apache Web Server running on Ubuntu 10.4 and I use a DynDNS service to make them accessible to the outside world via a domain and/or subdomain.
My configs currently look like this:
<VirtualHost *:80>
ServerAdmin <obscured>@<obscured>.com
ServerName <subdomain>.<obscured>.com
ServerAlias <subdomain>
[Code].....
This works fine from access outside of the network and all subdomains resolve to the correct directory.
The problem I am having is with accessing a subdomain over my internal network.
I can access the Web Server using the server's IP address: http://192.168.1.123/ but this always takes me to the same virtual host and I don't know how to distinguish between different virtual hosts (different subdomains).
Ideally I would like to access the same subdomains using http://<subdomain>/ where <subdomain> is the same as the subdomain attached to the external domain name.
I'm running Ubuntu Server 9.10 and I'm looking to setup an FTP server. I have SSH running beautifully and it's accessible from any computer whether it be inside the network or coming in from the internet (provided you have the administrator username and password ). I've tried Proftpd and vsftpd and have failed miserably so far. Which FTP server application do you think I should go with and how could I go about setting it up through my SSH connection?
My current setup is this:
- Ubuntu Server 9.10 with Fixed IP of 192.168.1.100
- 500GB Hard Drive
- SDA1 = 512MB ext2 /boot
- SDA2 = 2GB swap
- SDA3 = 20GB ext4 /
- SDA5 = 438GB ext4 /home
- One User (Username = administrator)
- Full SSH Capabilities
- IP Address to DNS provided by www.dyndns.org
- WRT120N Router with Remote Access and Port 22 Open
I basically want to set up a secure FTP server that anyone on the internal network can access as well as anyone from the internet (as long as they have a username and password). I want to setup a username and password for each user so that they all have read/write access to the same folder in my /home partition (I'll call it FTPSHARE).
I've 7 PC's on my network. I've to setup an internal mail service, to send mails inside the network. I've installed Fedora 12 on one machine and the rest run's on Windows XP. What all packages do I need? How can I configure it?
View 2 Replies View RelatedI'm in the process of setting up a script in perl to make 1,000's of curl calls to my companies application on our test server. Our software does all sorts of tracking of data based on IP addresses using geoIP, so i was wondering if anyone knew of a way to fake these addresses to the server?I know a big issue with the IP faking is the return path but i dont really need this. I also cant do it on the hardware level since the script is going to be picking lots of different IP's at random.Anyone have any idea if this is possible and if so, are there any known libraries i can use for this? I prefer perl but any Linux compatiblie scripting language is fine.
View 1 Replies View RelatedI'm planning to use Debian as the OS for a firewall machine, which will sit between my internet connection and the rest of my computers. Now my network is all wired, no wireless whatsoever. I'm using the onboard the motherboards cat5 socket which seems to be using the VIA rhine driver and I'm also using a 3com 100MBps card.
I can list the machine spec if you want but it's nothing special, an old Athlon 64 rig with 1gb ram and an OEM motherboard, it all seems to work ok apart from the internet doesn't' seem to work. Lenny seems to detect both cards ok and I even used the net install CD and it managed to download everything using the 3com card.
The strange thing is when I'm in Lenny, I can't seem to connect. I can ping google, but when I try and view a webpage, the browser just sits there with a while screen... Could it be that using 2 network cards is confusing Debian? Right now I've only got the modem hooked up the the 3com card, and nothing connected to the onboard network card.
I am using open suse 11.1 in my acer emachine laptop. Everything is okay except Network cards are not working. It says that firmware is missing or kernel problems. My network cards are Broadcom network cards. How can I fix it?

I've setup a webserver with LAMP and wondered if it was possible to edit the files without having to login through FTP, as would be the case if I was editing on an IIS server?
View 2 Replies View RelatedI've been researching this all day with no luck thus far. Basically I need to cutoff port 21/ftp access from IP addresses outside of my local network. My local IP range is something like 192.168.0.100 - 192.168.0.150 -- so anything outside of this range would automatically be blocked.
Any IP address outside of this range would be denied as I use SFTP for remote access, etc. from home, etc.
I've researched IP tables, tcp wrappers, etc. but am still unsure which would be best for what is probably a simple fix.

I have an OpenVPN(10.04.2 LTS) server running in bridge (TAP) mode. Its sitting behind a router and then a cable modem. The VPN works perfectly but I have a security concern. In order to allow the VPN clients to connect to the internet, I had to enable IPv4 forwarding on the server. Is this is a security hole? Can a hacker access my servers connection from the internet (without authenticating with OpenVPN) and access my network. Can someone use Ipv4 forwarding to access my LAN network from the WAN
I used this command to enable ipv4 forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
Without IPv4 forwarding my VPN clients can only access my LAN and router, but they cannot reach my modem or the internet.

I double checked my settings and they are correct. I can ping smtp.gmail.com.

I have installed Ubuntu on four machines at work and have been blown away. On my machine I have Apache setup for web development and other machines can "see" it using my IP address. I would like to have it so they can access by the name of my computer though. I have no local DNS server so I guess I need to hard code the relationship in each machine? Ideally I'd actually like to be able to use subdomains (which I use locally to avoid annoying .htaccess path problems). i.e. from another machine on the network to go to [URL].
View 3 Replies View RelatedI recently installed two PC with debian lenny (kernel 2.6.26). One is called serveur-debian1 and the second one serveur-debian2. I have installed gnome,samba, mysql5, apache2, php5, and Virtualbox,bridge-tools on them. On serveur-debian2, i installed an other virtual debian lenny with apache2,mysql5,php5,nagios and centreon on it to view my network. I remember having installed a soft to access nntp on serveur-debian2 in order to test nagios.
Since a few days, i have problem to access to my servers. rom my windows 7 client, i try to ping serveur-debian1. Response is OK but not for all resquets Always from the same computer, i try to ping serveur-debian2. Response is OK but not for all again.
When i launch a ping on serveur-debian1 and serveur debian2 at the same time i have:
ping 1 to 10: serveur-debian1: response OK
serveur-debian2: no response
ping 11to 14: serveur-debian1: no response
serveur-debian2: response OK
ping 15 to 25: serveur-debian1: respone OK
serveur-debian2: @ip serveur-debian1 network unreachable (there's no error, it shows me the ip of serveur-debian1)
If i switch on the debian virtual server on the serveur-debian2, and i ping it at the same time, the response is OK for all resquests. The problem is very strange. I can't have a correct connection and when i launch a request from a software which access the mysql server, the requests failed ...
I installed the driver for my network card. iwconfig and ifconfig are all responsive to connecting to the network, I'm given an access point address. Then, I try to connect to a website and no dice. ping www.google.com yields no result. What gives?

View 9 Replies View RelatedI'm having a strange problem with my network connection/DNS. I turn computer the on and it recognizes and connects to wireless or wired but I can't access any Internet resources or my router. If I ping the default gateway, I get no response and I get DNS errors from any network services that run at start up. If I stop and start the network daemon then it all works fine until the next time I turn on my laptop. It does this for both wireless and wired connection.
I've tried to edit the network interface information in YaST but it says that configuration is handled by knetworkmanager and I have no idea where that information is accessed. I should point out that it all worked fine until I tried to connect to open WAP at my school and couldn't so I connected to the wired network. Next morning I had this problem when connecting to my home network. My questions are 1. What could be the cause of this error and 2. where does one configure the network interfaces when using knetworkmanager
i have 3 comps(running suse 11.3) and a laptop(running vista sp2). i have installed samba on all suse comps. i have a printer attached to one of the comps and it has been shared also the internet connection on that comp has been shared. all the computers are connected using lan cables through an ethernet switch. i also have a wireless router which is connected to the ethernet switch.
I am able to view all the comps on the network except the laptop running vista. all the desktops are visible on the network and are able to print and share files on the network and also connect to the internet. the laptop running vista can connect to the internet but its not visible on the network and nor can it share files across the network or access the printer.
I dont know were to begin to solve my problem and I have been googling for hours to get a hint without any success. I'm runnning a Counterstrike Server on my virtual openSuse server - I'm exploring so don't justify what I am hosting at the moment
I want to make it possible to gain access to the cstrike folde via a ftp login. But I really have no idea were to start. The server is also a webserver, where I can ass FTP accounts for my apache vhosts via plesk - but I dont think this is the solution of my problem, isn't it?
New SUSE 11.3 install connects to network/internet etc OK with DHCP-assigned IP address. When I switch to static IP, I can no longer ping internal network, or anything else. This works OK with SUSE 11.2 on same hardware and (as far as I can see) same setup. Some diagnostics are shown below.
Firewall
Disabling the firewall makes no difference.
Not using a network manager (can't see how to assign fixed address if I do - all greyed out).
ifup eth0:
eth0 device: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
SuSEfirewall2: Warning: no default firewall zone defined, assuming 'ext'
(not sure why the warning - eth0 is assigned to external in the firewall setup).

So I am looking to modify my network cards MTU (for some testing purposes), and I only know how to do it it Windows (via command prompt ping command with special flags) and not in Ubuntu.
Any easy way to figure out proper MTU numbers in Ubuntu?
Toshiba T110 laptop, 4 meg ram, kernel 2.6.31-14; multi boot Suse / Ubuntu / Windows; Atheros AR8132 Ethernet card; Realtek RTL8191 SE wireless card.
Installed 9.10 from an old DVD lying around - everything appeared to go ok, but no networks cards - Ethernet or wireless - were detected during the install.
(Later versions do not install - problems somewhere with video card - I need to allow multi kernel selection - but this is another issue)
Does this mean that this install is toast, or can it be saved?
I have two D-Link network cards installed in my computer. The Ubuntu 10.04a2 installer seemed to recognize only one of them, though I know both are functional. I plugged a CAT5 cable in here, connected to my home network (with Internet). The installer proceeded happily, configuring DHCP and synchronizing clocks. However, when I rebooted after its completion, Ubuntu didn't recognize that I was connected to the network. I re-jiggled the RJ-45 connector, to no avail. When I run "System Testing," it does list both network cards during the Network suite, one being D-Link, and the other "James Bond" or something. So, what gives?
