Backround:
I'll have 2 routers:
- ADSL-router (D-link DSL-2640U)
+ NAT on (needed as one static IP from ISP)
+ Server's IP as 192.168.X.xxx
+ router firewall port-forwards set for needed ports (21,22, 80 etc) to 192.168.0.xxx - 2nd LAN-router
[Code]....
Is there any setting/file on Debian-user-machine, where I could fix that abc.mydomainXYZ.com/defg is always in something to do with 192.168.X.xxx
I'm trying to set up a *simple* MTA in my local network. The only thing it should be able to do is send system / daemon mails to admin@mylocaldomain. but at the moment I'm pretty much overwhelmed by everything i *should* know in order to set up this MTA
my infrastructure:
- servers:
* test01.mylocaldomain --> should send mails (with exim) to admin@mylocaldomain
* dns01.mylocaldomain --> dns-server
* mail.mylocaldomain --> mail-server (postfix / iredmail package)
I configured exim to be in "internet"-mode. now i have a variety of errors I can choose from (and a variety of solutions that i don't like ).. my test is always an email from test01.mylocaldomain:
echo "Hello World" | mail -s Testmail admin@mylocaldomain
- after running the config, i get the error: admin@mylocaldomain: all relevant MX records point to non-existent hosts --> google says, edit and udpate update-exim4.conf.conf --> dc_relay_domains='mylocaldomain' --> but this exim installation should not be a relay at all. it should only be able to SEND (to this domain), not deliver it. or do i get something wrong?
- after i added dc_relay_domains='mylocaldomain', i get --> SMTP error from remote mail server after RCPT TO:<admin@mylocaldomain>: host mail.mylocaldomain [192.168.x.x]: 550 5.1.1 <root@mylocaldomain>: Sender address rejected: User unknown in virtual mailbox table --> but i don't want to create an account on the mailserver for the SENDER...
- ...so i thought, i'd config exim with the domain "test01.mylocaldomain" (including the server name), so that the sender is clearly from another domain than the mail server handles (e.g. user@test01.mylocaldomain).. but then i get this --> SMTP error from remote mail server after RCPT TO:<admin@mylocaldomain>: host mail.mylocaldomain [192.168.x.x]: 450 4.1.8 <root@test01.mylocaldomain>: Sender address rejected: Domain not found
I really just wanna send mails in my local network.
I am working on a Debian 2.6.26-19 Distribution with exim4 as MTA. After a system restart a problem occurred with delivering emails to local addresses. These local addresses use a 1and1 mailserver for email. The MX records for the local domain are set correctly but exim does not use a DNS lookup for these addresses because it identifies them as local addresses. I figured this out by executing the exim4 -d -bt command. The dns lookup part of the result looks like this (I replaced the actual address with placeholders):
[Code]....
The eventual result of the exim4 -d -bt command is: [user]@[domain.ext] is undeliverable: Unrouteable address How can I make sure, that exim4 makes a DNS lookup for the local addresses instead of skipping it? I know that I have to edit a exim4 configuration file, but I could not figure out which and how.
Can Debian act as a Windows Domain Controller? I'm just curious because my boss recently tossed out some old servers and I grabbed them. They're good machines but I can't afford to pay $1000 for Server 2003 R2 just to setup a domain at my place and run Endpoint Protection and such. I've never used a domain setup in Linux before so I thought I'd ask and possibly try to, if Debian/Linux is capable of such a thing.
View 6 Replies View RelatedI'm having problems when trying to view my web site from inside my firewall and router. The web server works fine and will resolve from IP address on the local network and port forwarding works for external connections. The problem stems from when I orignally setup the server; I left the domain name field blank when going through the installation process.
I've had a look at the man pages and had a search on Google but cannot find an answer that works. I've changed a few things in '/etc/hosts' and '/etc/networks' but when I make changes they have no effect on the problem. My web site is on a no-ip domain which is [URL]..
i have several sites hosted on one machine (Apache 2.2 on Debian). They are configured at /etc/apache2/sites-available/ with this configuration (part of it):
RewriteMap lowercase int:tolower
RewriteRule ^(.+) ${lowercase:%{SERVER_NAME}}$1 [C]
RewriteRule ^(([^./]+.)?site1.com)/(.*) /www/site1.com/www/root/$3 [L]
RewriteRule ^(([^./]+.)?site2.com)/(.*) /www/site2.com/www/root/$3 [L]

In the office there is a local network with samba+openldap PDC. The local domain name is company.net. The company desided to create a corporate Website on a remote hosting and desided that the site's domain should be company.net which is same as local network's domain name. So now it is not possible to reach that corporate website from within the company's local network because, as I guess, bind9 which is installed on above menioned PDC looks for company.net on a local webserver. Is there a possibility to let people from this local network browse the remote site?

I installed debian etch, it runs and does connect to the internet fine through a linksys router...the linksys router is connected to my cable modem...now..
I just registered for a domain name (ex. mydomainname.org) with Verio....this is where I am stuck.
I installed apache 2, a web server, file server (all seem to work) I need to know what files I need to configure to have my machine actually BE that domain name.
Ex. my linksys DHCP IP addresses, the linksys gets an IP from the cable modem...my yquestion is ONCE I register a domain name with verio...how do I configure my end so it "knows" I am that respective domain name...I think I need to configure the following, but knot sure how to do it: resolv.conf, hosts, and interface?
What would be necessary to run an ftp server (or a web server) on my local PC so that other people I know could access it and download stuff from it? The idea is to share photos, videos etc with friends/family where the files are a bit too big for email. (All 100% legal, own-content, no copyright issues, needless to say). Security isn't that vital, I'd just put files in the ftp directory, email the link and let them download the files, then remove them again. No passwords are required, and no uploads.
Obviously there's the problem that both computers have to be on at the same time, and I assume I'd have to change my computer's firewall settings and my router's settings to allow the traffic through, but my question is more basic than that - is it even possible? My internet connection is through a router, and as I understand it, my router has the IP address, not my computer. So I can connect through my router using my computer's IP address, but only my router knows my computer's IP address, and all the rest of the internet just sees my router and its IP address. Which means (I think) that I can't just send my IP address for my family to connect to, because that only gets them as far as my router, and the router would have no idea what to do with such requests. Am I right so far?
So is there any way for my family's computers to contact an FTP server or a web server running on my computer? Or does it require some kind of intermediary server to act as a traffic-forwarder? Is there such a thing? I'm assuming that setting up little private torrents would be fiddly and inefficient. Or would it be better/simpler to use one of the free filesharing services and put up with the (sometimes not too family-friendly) adverts associated with them?
Two nights ago I decided to switch from testing to unstable. Since then I am able to connect to the internet, but not to anything on my local network. I am unable to ping this computer from another one on the network. This computer is connected through wireless. I thought that something might have changed with iptables that was blockinghe localnetwork. I tried to "flush the iptables settings with "iptables -F". Since that didn't work I uninstalled iptables (which didn't work and I reinstalled iptables). In my browser I tried to connect to my router and that doesn't work either.I connect to this computer daily through ssh and connect to a NAS. Without ssh and my NAS I feel kinda lost

my tablet can receive ip, can see ftp on server but can't see anything in my home network.
i rarely need my wireless, and i want it off by default, i am going to disable it during bootup with
echo 0 > /sys/devices/platform/acer-wmi/wireless
what would be the proper place for this? if i put it in rc.local it will be executed very late, i'd rather have it sooner. if add a new script to init.d, then run update-rc.d, i would have to adhere to the start|stop|reload structure of these scripts, right? or do i go a totally different way about this?
I have a new Debian 5.04/ppc install on a G5 tower and it's not able to browse the local network. The clean install could see the network, then I installed the Samba server, and it hasn't worked since. Samba server never really worked, and I'm guessing I messed something up. I've reinstalled network-manager, and removed / reinstalled samba.
I have a small home network (6 machines) running wired and/or wireless, pc/mac and linux.This machine can PING other machines by name and IP address.This machine can PING itself by name and IP address
Other machines can PING this machine by IP address only, not by name.Nautilus network browser only shows the "Windows Network" icon, which, when clicked, shows an empty window.I've got networking up fine on all my other machines but this one is stumping me.
I have three Debian systems running, along with several XP laptops, PS3 and two DirecTV systems. I use two of the three Debian systems as media servers, and the third is an older system mostly for playing around with. My home network is running fine with the following nuisance. The two newer Debian (Lenny) systems are <barney> and <mitzi>, the older is named <oscar>, running Debian Sarge 3.1. From either locally or remote login to <barney> and <mitzi> I can ssh into either of the other two systems, however when logged into <oscar> I cannot ssh by name to either of the other systems. e.g. ssh: mitzi: Temporary failure in name resolution..However, from <oscar> I can ping outside my network (e.g. ping www.google.com) with no problems.I can also ssh to the other systems via IP address, just not by name.
I've compared the /etc/ssh/ssh_config, /etc/resolv.conf, /etc/ssh/sshd_config and other files between the two systems and not seeing anything peculiar. arp, route, etc., don't show different behavior between the systems either.
At home I have two computers running linux connected to the same router. I would like to be able to connect them so that I can move files between them and execute simple commands. What is the most simple way to access a prompt on the other computer or to mount a partition currently used by the other computer?Using the www it is possible to connect two computers using ssh, but it should be easier to do this over the LAN, right? I have been googling a lot but not found anything.

I have a strange iptables issues. I have just built a new Debian install and starting adding some real basic rules (see below) the problem seems to be that the localhost itself can't get any returning traffic. That is, it seems to be allowed outgoing traffic but not the connected, returning traffic. Ordinarily allowing Established Connections would resolve this, see the rule below, but it hasn't. Why this doesn't work. Removing the last DROP in the INPUT chains obviously makes the traffic work!

iptables -A INPUT -j ACCEPT -p tcp --dport 22

I have setup Postfix + Dovecot on my basic debian 5 server. If I send a message to a localuser@mydomain.com from mutt, it delivers just fine and is visible when viewed through squirrelmail, I can also send just fine.

I have some beginner questions about DHCP, Avahi, and configuring a small home LAN.Suppose I have a dynamic IP address assigned by my ISP, which requires DHCP be enabled in my dsl modem/router/"firewall" [sic]. Suppose for simplicity I have just one PC behind the dsl modem.I think "enabling DHCP" in the modem/router means that a DHCP client runs on the router, which communicates with a DHCP server run by my ISP when I boot up a PC on my LAN. Is that guess correct? Can I get DHCP to assign a particular local IP, say 192.168.1.10 (which is not the one taken by the router--- for this discussion, let's say that is 192.168.1.0) to my PC each time I boot it up?
Now suppose I want to build a stand-alone firewall, so that my LAN will have the firewall and the first PC behind the modem, with the first PC virtually behind the firewall. By default, I think these will both have DHCP clients running which I need to configure properly. The firewall should also have a DHCP server which should control how local IP addresses are assigned, correct? I should try to arrange that the LAN has only DHCP server, only one NTP timeserver, only one DNS nameserver, correct?My first PC seems to have installed an autorun client called Avahi, which performs DNS multicast services and incorporates something called zeroconf which seems to have something to do with remote desktops, which I don't need and which is a potential security hazard. But it seems that Avahi is an intrinsic part of the KDE desktop and cannot be removed. Just want to be sure that Avahi can coexist comfortably with dhcp3-client, which is also installed on that PC. They perform different tasks, correct?If I can get the stand-alone firewall to work, I know I need to turn off the commercial firewall in the dslmodem/router/firewall device. Should I purchase a bridge and try to turn off the routing function also?
I am trying to set up a wireless 'test' box to use on a private club (11,000 acres). The initial tests won't need anything fancy, it will just be checking the visibility of a hotspot from a high-point in the middle of the property. But if it proves to have good visibility, later tests will be (hopefully) promoted by the club and made aware to members. I would like to set up a captive portal to redirect them to a comments page where they can post a quick message if they were able to connect ....
Most of the examples I see online of captive portal are based on having an internet connection and/or a NAT scheme set up. I just need a hotspot and a single web-page for these promotional tests. If possible, I would like to trigger any devices capable to suggest or otherwise open a browser to go to the promotional landing page ...
Also, one more quick question, this is to eventually be an 'open' internet for this test - most of the wpa set-up examples show using a passkey. Is making an open wifi as simple as not including the passkey or is there something else I would need to be doing?
I'm trying to TFTP router configurations to a server in the same local network without having to first make files in the server's TFTP directory . The transfer of a config file from router to server works perfectly if I make a file with touch and then chmod the file with 777. I found information that says to use the -c or --create option in the TFTP configuration file (/etc/default/tftpd-hpa) if you want TFTP to work without having to create the files first. The problem is, I have set this parameter and restarted TFTP , but it is not working.
