Networking :: Connecting To A Printer On Another Subnet
Aug 19, 2010
I have some trouble setting up a printer on my network. My network is divided so that all wired connections are in one subnet, while all wireless devices are in another. My printer is Canon MP640 and is connected via wireless. When I use the network printer scanner utility from Canon, it will only scan my wired subnet, and is thus unable to see the printer. I can ping the printer, so there is no problem with subnet segregation.
On my router, I have Debian and iptables. My initial thought was that I could somehow set iptables to just forward all packets to an address to my printer. This address, of course, wouldn't exist "physically". But I have no idea whether or not this is the right approach. A suggestion I received from a colleague was to set up forwarding of broadcast packets. However, I am unsure whether this will have an impact on the wired subnet. If any of you could conjure a magical iptables rule for this or have suggestions other than plugging the printer into the wired net

I have TWO L3 + router switch (say switch1 and switch2). I created VLAN100 with VLAN ID 100 in both the switches. I created router 192.168.1.1/24 in Switch1. I created router 192.168.2.1/24 in Switch2. Switch1 is connected with 1.x/24 PCs. PCs are configured with 1.1 gateway. Switch2 is connected with 2.x/24 PCs. PCs are configured with 2.1 gateway. Both Switch1 and switch2 are connected by a trunk to carry VLAN100 data.
1)I have few PCs of 1.x connected to say Switch1 Is it possible for PC with IP 192.168.1.100(x) to ping PC with IP 192.168.2.100(y)?What are the configuration required in both switches to make them communicate ? All the device in both the subnets should ping/communicate with each other.
2)Move PC (192.168.1.100) to switch2. Move PC (192.168.2.100)to switch1.What will happen when PC(1.100) ping (2.100) and vice versa?What will happen when PC(say 1.80 in switch1) pings PC (say 1.100 in switch2) and vice versa? What will happen when PC(say 1.80 in switch1) pings PC (say 2.100 in switch1) and vice versa?

While I was setting up CentOS 5.5 for my first time I faced this problem which is connecting to a printer is not possible, my tutor told me you need to change from eth0 to eht1 or eth2, what does that mean? And if I do this, how can I connect a printer which I have its name and IP address.

When I was on Windows I used to be able to connect my laptop to a printer that was plugged into the computer downstairs via the wireless network. This network is still in place, only now I am using ubuntu I haven't got a clue as to how I connect to this network,or if it is even possible at all! how I would go about printing over the network when the other computers on the network are all windows machines.

I'm trying to set up a Samba printer in Debian linux. The printer is being shared by a computer running windows vista. Some of the information I've got in the process. Sharing seems to be working, the printer seems to be detected and authenticating (I've tried invalid values and the utility I'm using to set things up says it cannot verify when I use invalid values, but with things as they are it claims everything checks out).
When I go into CUPS it says it detects the printer and everything is working. However, printing a test page causes the job to be immediately complete and nothing happens. It seems that the job is getting lost somewhere in the process. Could it be a firewall issue? I feel like the right ports must be unblocked since I can query the computer and verify the printer, etc. I have a laptop with vista which I installed a printer on and was able to print to that computer just fine. So it doesn't seem to be a Vista thing.

I am unable to connect to my printer wirelessly. I get this: Idle - "Connecting to printer..." The computer never connects. I can print a configuration report and get the ip address. If I type that in a webrowser, I get an error: unable to connect. Even if I plug the printer into the computer by a usb, I am unable to access the printer's ip address in the webrowser. I'm not sure how to proceed on getting the printer working wirelessly. It is a hp 6940 I use the HP Deskjet 6940 Series hpijs, 3.10.2rc1.9 driver. I have only recently been having printer problems. The printer has been hooked up on the same network for years. It still prints via usb.

I don't know what I'm missing here. I am trying to share a printer from my linux box to my windows workstations. I can see the printer and connect to it but when I print a test page nothing happens. The job goes to the windows queue and the disappears. I have added the PS driver for windows to the /etc/samba/drivers directory. I have also downloaded and tested the cups driver. Following is my smb.conf entries.
[global]
; netbios name = SRV
security = share
printcap name = cups

My home/small office LAN has network connected printers. Some use wire. Some are wireless. Each has a unique static, private IP address on my LAN. Each workstation has a primary printer, but all of the printers are visible and used by all family and office folks. The symptoms:boot a workstation, connect to LAN printer,
start a queue
print things
suspend or shutdown the workstation
resume or reboot the workstation
various troubles
Even if there are no jobs queued (everything printed already) at the time of suspend, I must routinely "thump" the printer or workstation of both to make printing work again. I am concerned with Ubuntu Jaunty towers and laptops. All of the printers are HP something with a built-in wired or wireless ethernet connection. I'm not concerned with win-dose workstations on the LAN (unless interaction over there is causing other grief)!! For example, a win-dose spooler fails to end a print job properly and let go so that others may use the resource.

I have finally given up trying to get to a printer on my windowsXP pc to work with my linux box and need some assistance. The printer is a hp photosmart c5500 series. My linux box is running lenny and I have installed the cups and samba applications. The linux box is networked to the win pc on a win network using a eth0 link. The link works as I have internet and e-mail connections. I have configured the smb.config file as follows:
[Code].....
I have run the tests in the samba checklist and the connection is apparently working. Pings to the windows pc,, the notebook, and the linux box all return the proper results. The "smbclient -L w.x.y.z" return shows the windows shares that includes the above named printer. When I try to connect the printer using the kde cups wizard or get into the c drive on the windows pc I get the NT_status_access_denied message. I get the same return when I try the "smbclient //username:passwd@wincomputer" I downloaded the appropriate drivers from HP and tried the lpadmin comand and instructions in the Debian mini-Howto but get the return of "lpadmin: No such file or directory" when in fact all the files exist and have correct permissions etc. I have a Ubuntu OS running on a notebook computer (dual boot with windowsXP) with a wireless link to the same router that accesses the printer without a problem. The smb.conf file I am using is based on that I found in my Ubuntu OS but apparently something is different.

I'm using Fedora 12 KDE, and I'm trying to connect a Lexmark printer. It's a printer that I can connect to in other KDE distros. When I try to connect to it through the system settings printer manager I get a popup window that says, "Password may be incorrect", and then it goes to the new printer window. However, there is no option for a lexmark printer, lpd, ipp, or anything in the left menu bar. There's only an option for other, and a little box that asks for the uri. Am I missing a package, or is this normal behavior? Do I have to somehow open this up in sudo? Am I missing a package? I have cups, foomatic, and ghostscript installed.

I have a client.conf in /etc/cups that points to a CUPS server. I don't have u/p access to this server. I also want to print to a local printer (USB), but I can't set it up - ALL attempts bring me back to the CUPS server password prompt. Is there some line I can add to the client.conf to allow me to use a local printer?

I have 2 x PCs and a NAS. Both PCs have 2x NICS. PC connectivity to Internet is via an ADSL router. Current config: Thus far (by choice) I've used static IPs in the 192.168.168.x range for my internal network, connecting all PCs and NAS via a jumbo frame enabled gigabit switch. This has facilitated moving data between the PCs and the NAS at high-speed. As both PCs also required Internet access from time to time, both are also connected to the ADSL router using the 2nd NIC and using subnet 192.168.1.x. I'm sure some of you are shaking your heads by now, but it works well and has been entirely hassle free.
However, I've an app running on the NAS that I'm keen to get Internet connected also. As my existing network devices are not using DHCP I figured the simplest method would be to change my ADSL router configuration such that it is in the same 192.168.168.x subnet, change its DHCP server settings to serve IPs in the same subnet (but in a restricted range I know won't cause any conflicts with the static IPs) and problem solved. On changing the ADSL router confiruration with all machines already booted up and configured as described above, everything worked. All devices could see one another, and access the Internet. On later rebooting the system this no longer works
- Internet access is fine but PCs don't see one another or the NAS. If I disconnect the ADSL Router from the PCs then all devices see one another again.
- Does having 2x NICS on a single device each assigned unique IPs in the same subnet create an issue and can it be overcome? I'd like to overcome it because making one of my PCs the gateway forces me to have it on anytime another device needs access.
- If I'm forced to use Internet connection sharing with one PC on the network connected to the router, how do I best configure this?
- One of the things I need to retain is gigabit connectivity between the PCs and PCs and the NAS (currently achieved by 192.168.168.x subnet being linked via gigabit switch).

I am trying to make Apache web server, it's work but cannot be browsed outside my subnet.I am on huge LAN network, not sure how it works, know it have TL-SL2428WEB Smart Switches and probably some kind of DHCP, every user have maximum 64KB, just plug UTP cable, and I have static address on that subnet like: "my.sub.net.ip" witch I know from Java NetworkInteface class or when I try to update IP on my www.dyndns.com Dynamic DNS account with ez-ipupdate, but my subnet is connected to Web with another IP like "my.isp.provider.ip" witch I get from whatismyipaddress.com and I check that is my Cable ISP provider web IP. It is possible that there is more subnet layers between these two IP.Problem occurs when I try to access to my web site from another computer. When I set dyndns host name to be my.sub.net.ip or use localhost everything works fine from my computer, I can access my web site, Apache work, I can use ssh. To illustrate you it work like this: Go to DNS server, find my host name, get my "my.sub.net.ip" and say "This is actually my localhost IP, no need to go on Web, lets loopback". But when I try from another computer even from my college's computer on same subnet it don't succeed. When host name is set on "my.isp.provider.ip" of course nothing works.
We, users of LAN, don't have access to our LAN nor we have admin. For example sometimes we stuck without net and we cannot even press reset button on switches or something like that, we have to wait for day to they, owner of LAN, order some professional to do that. It seems they are just user of Cable TV and IP, and they bay and install LAN without any kind of admin. Also, I use Fedora 13, with httpd, ssh and others packages that comes with Fedora 13 DVD. I know to write bash scripts, use yum, very good in C++ and Java, great programmer, but newbie in networking, , a very little Perl, html, web servers, I heard for DHCP, DNS, NAT, IP forwarding. How you see it is problem in my lack of knowledge about networking. I hope that I succeed to describe by problem with enough details. Please, try to help me. I be very graceful for any kind of help. Don't afraid to bomb my head with any kind of information hard to understand.

I've rent a server from a Germany data center,They use a single IP as their gateway that is not in range of my servers IP,Strangly server is working well and when I use 'route -n' command the gateway which is in other subnet appears properly./etc/sysconfig/network contains no gateway IP and I don't know how they set the default gateway while after reboot the gateway is the same, also the IP is static and there's now DHCP.I need to know how they did it so I can do the same on my VPSes.

I have 2 NIC's in a box. One of them is external and doesn't matter for this question I don't think.
The other NIC is 192.168.100.3. It hosts an iSCSI Target and SMB Share on my LAN. It's works great.
I have another PC that has NIC at 192.168.100.101 and it hosts my DHCP (Scope: 192.168.100.5-25) server for my LAN.
I have a hardware firewall at 192.168.100.1 and it serves inet to the LAN on a different external connection.
So...
I currently have a WAP (cheap p.o.s. netgear router in WAP mode that keeps overheating). I want to eliminate the WAP device and add a WiFi NIC to the Top PC above.
So, on the first system I would have:
NIC 1: External IP and External Gateway
NIC 2: Static IP 192.168.100.3
Proposed WiFi NIC 3: Static 192.168.100.4
Question:
If I bridge NIC 2 and NIC 3 like this:
# brctl addbr br0
# brctl addif br0 eth0
# brctl addif br0 eth1
Then I simply put the WiFi in Ad Hoc, will another WiFi in Ad Hoc (for example my laptop) be able to "see" 192.168.100.101 (DHCP) & 192.168.100.1 (Gateway) (via WiFI 192.168.100.4 through the bridge to 192.168.100.3 and on to the LAN)?
Also, can the two NIC's be bridge together even though they are the SAME subnet?

I have read NUMEROUS tutorials and explanations on the net about this, but they all seem to assume an informed understanding of IP networking. I have limited knowledge (basically I know how to set up my own home network and use the normal commands for troubleshooting.).I am doing a project at work which requires networking our new store with our original store (throughA VPN).I am just trying to understand in the most basic way how sub netting and subnet masks work. I don't believe this is necessary knowledge for setting up the network via VPN, but I would just like to understand it and I feel like I will be prepared to study further. basically:
1. How does a network mask isolate a particular host on a network?
2. How does changing the mask allow for more addresses to be used?
For example, if my address is, say, 192.168.1.36, how does 255.255.255.0 isolate my machine to receive traffic? I suppose what I am really not understanding is how it does this with more than one host on the network with the same mask.

I installed apache2 on my Ubuntu machine and I am trying to access the server from another subnet. The server is connected using ethernet and has a static ip address. I can ping from the server to any machine in the other subnet but non of the machine on that subnet can ping the server. iptables does not seem to be running
Code:
# service iptables status
iptables: unrecognized service
and its rules are
Code:
# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
[code]....
What is preventing my machine from being accessed from the other subnet?

I'm trying to work out how to route all traffic destined for the internet from all devices connected to eth0 to a wireless router access point via wlan0 on my Slackware box. I also have dhcpd providing ip addresses on the same subnet to any device connected to both eth0 and wlan0.
Diagram:
Code:
____________ ____________
[ ]=============> (wifi) ==============>[ Router / ]
|Workstations| __________ |Access Point| 192.168.2.1
[____________]==>(eth0)==>[ ]<==(wlan0)==>[____________]
192.168.2.253| Server |192.168.2.254
[__________]
If I connect to the router/access point via wireless or directly to the Server via a crossover cable I can obtain an ip address from dhcpd, so that works. As far as I can see I just need to how to route between eth0 and wlan0 then I can provide internet access to those devices!
ifconfig:
Code:
eth0 Link encap:Ethernet HWaddr **:**:**:**:**:**
inet addr:192.168.2.253 Bcast:192.168.2.255 Mask:255.255.255.0

Im trying to configure a GRE over IPSec connection between two subnets. The IPSec tunnel is opened and now I want to add a GRE tunnel over it.So, what I didn't understand is why I can't route my subnet over the tunnel, once the only route I have there says that it should route the tunnel IP over the GRE01 interface. Any hint? Thanks.

I'm living at a friend's right now, and he's got a wireless access point in the house that I set my laptops wlan0 interface to route through the eth0 to my desktop. It's been working fine for internet sharing and internal networking ( ssh and ftp ) between the laptop and the desktop, but there's a problem with both subnets being able to communicate with each other, and I haven't been able to solve it with DNAT either.
The wireless access point is 192.168.0.1 and has its own lan on 192.168.0.0/24 of which my laptop is 192.168.0.5. I setup the little subnet I created by routing with the laptop to 192.168.1.0/24 and my desktop is 192.168.1.50. With shorewall I can configure iptables to DNAT all of my ssh traffic destined to 192.168.0.5 to 192.168.1.50, but the problem seems to occur when ssh on my desktop fails to connect rather than the DNAT failing.
Using iptraf I've seen that all of the routing does work properly, because I can see on the connection in iptraf that only the SYN packet is being sent from a 192.168.0.x address, there is no ACK packet sent back. I believe this is because in the connection dialog it always shows a 192.168.0.x ip as the source of the connection, but I don't have a route to 192.168.0.0/24 from 192.168.1.0/24 setup and I'm unsure of how to do so.
I'm pretty much in over my head because I don't know what is wrong, I thought it should work like this. Everything else from port configurations, to the configurations of the software itself seems fine so I don't think it's anything like that preventing a connection, but I can't think of what it would be aside from the lack of routing between each subnet.
Is there anyway to just add a route so that 192.168.1.0/24 and 192.168.0.0/24 can communicate with each other directly? I know there should be, I'm just not at all sure how it would be done.

does somebody know how dnsmasq / iptables need to be configured such that requests to my public IP from lan are correctly NAT'ed to the host that handles them? Currently my routing device treats them like "oh, these are anyway for me, gnam gnam" which actually doesn't work.Unfortunatly setting up NAT rules that redirect requests from my lan correctly as they are redirected from wan is an option I would like to use only if there is no other possibility.I would like some kind of solution that treats packets that are sent to my public IP as normal packets that are not looped back before they even get out. So they would need to be at least sent to the wan gateway where they are directed back where my firewall can successfully treat them like all other public requests.
