Software :: Can't Access CUPS Interface?
Dec 3, 2008
I'm unable to access the CUPS interface (localhost:631). I used to be able to, but now, everytime I try to, a Page load error comes up with "can't establish a connection to the server at localhost:631." I searched the Ubuntu forums and Google and tried a few things (including installing CUPS v1.3.9) with no change. I've tried stop and staring cups, but nothing is working. Has anyone come across this issue and found a fix for it?

I can connect to the HTTP cups interface (localhost:631) but if I need admin priviledges, giving my id/pwd doesn't work. I don't see any "cups" group defined.
Otherwise, how do I enable a printer? I could disable it using the KDE printer management interface, but I can't re-enable it using same... Answer: /usr/sbin/cupsenable

I am trying to configure CUPS and when I click on Adminitrator to Add A Printer, I get Forbidden after entering my root username and password. Anything I'm doing wrong?? In the past, it was just a matter of putting my username and password and walking though the installation. The printer is connected to the computer via USB and is being seen on the machine.

I'm having all sorts of problems connecting an access point to my computer, but here is one piece that I hope will get me going, if I can get it solved.My computer has two network interfaces, eth0 and eth1. eth1 connects to the cable modem and thence the world, and works fine. eth0 is supposed to connect to the access point over a private network. Here is the output from route with my IP address blotted out:
Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface

I have my centos server behind a Linksys router. I'd like to access the router's web interface to open and close certain ports. How do I access the router's interface ?
Prior to this, I had a windows machine. I could type in the router's IP in 192.168.1.1 in the browser and get access to the interface.
How do I go about now ?

I have a printer configured on my Ubuntu server using CUPS amd made it available to the local network. The printer is recognized on my other Ubuntu machine without any problems.
But on my Suse laptop, the printer is not recognized. Using the YaST printer Configuations, I choose the option "Recieve Printer Information from Remote CUPS servers. But no printer is found.But... when I choose Do All Yout Printing Directly via One Remote CUPS server and enter the correct IP address (192.168.1.100), the printer is found andI am sure the printer info is broadcasted because it shows up on my second Ubuntu PC. But why is it not recognized by default on my Suse machine

I have web application running on my server and can access this over the GUI.
This morning I can no longer access the gui interface. The activity LED flickers non stop on my nic card. I cannot ping or ssh into the server. However can access it directly from console and system is responsive when doing that. So i think this is a n/w issue... Any thoughts? How can I troubleshoot this?

I have set up nagios on Suse 11.2 and it is working fine on the localhost. I can access localhost/nagios, <ipaddress>/nagios in the browser and it loads up the nagios webinterface. If I try on a computer on the network with <ipaddress>/nagios the request times out. I have tested that I can ping to and from both machines (nagios machine and the machine I am trying to access the interface from).Some detailsNagios is running in a hyper-v VM. I installed it through yast2. Communication is run via a switch and sonicwall firewall but firewall has allow all within the network.I have a feeling it's some apache2 setting that I haven't configured or something blocking port 80.

Running: Ubuntu 10.10
I'm in a bind and I don't know how to get what I want. Nmap shows ipp running cups on port 631. Great, simple enough I uninstall cups, along with its dependencies. A new portscan reveals that the port is closed SUCCESS, but... Ubuntu Update Manager nags me @ every restart about the "important security" updates. I can't lock the version of cups in Synaptic, because cups is not installed! So you see I'm in a bind. If I have cups installed I have an open port, and if I uninstall cups the update manager nags me. What do I do? I've tried:
- stopping the cups service and issuing the chkconfig cups off command... (doesn't close the port)
- uninstalling cups... (update manager nags)
- fuser -k 631/tcp (great, but @ reboot the port is still open)
Please teach me how to close this port / stop this service / tell update manager to shove cups.....

2011-04-11 11:57:03 UTC I don't know what happening with my centralized log-server running octopussy. Currently it is working in a vmware setup with approx 980 Mb ram and is set in bridge mode. Currently is it set to receive logs from logs devices which are 4 in number one of which includes the core isg-1000 device. This setup is still in its test form....now what happens after some time (sometimes it taken days and sometimes just hours) when the connection (https) is suddenly lost to the apache and i can no longer access the interface. What happens more strangely my Ethernet interface gets shutdown on ubuntu. I have to restart the services by issuing /etc/init.d/networking restart.
Even at times it itself start receiving network packets on its own; without even restarting; i don't what the hell is wrong with the server. I cannot understand its erratic behavior. I need a sound and reliable Ethernet connectivity at all times because coz of loss of connectivity in my case would mean loss of logging functionality. I dnt want any time-gap in logging ...as im currently logging some highly critical devices on this server.

I have a Linux mail server (Fedora). This server was set up long before i joined this organization. Now I have these issues I would request assistance:
1. I am not able to access the Graphical User Interface(gui) on this machine. Startx does not work. I have also tried using combination keys alt+ctrl+f...keys but no progress. As a result am not bale to do some tasks.
2. The clamav that is on the machine has since become outdated. Efforts to update it to latest versions have failed. How do i get to update clamav and protect my system?
3. Because of not being able to access the gui as well as the inability to update clamav have led to my server apparently sending spam mail which in turn have led to my public ip being black listed in a number of sites. Now how can i secure this server so that it stops sending the spam mail and hence avoid future blacklisting?(NB am using postfix and the server sits behind a router which connects to the Internet)
4. I have observed that the server has some iptables rules set but everytime the server restarts the rules stop. I have to manually restart them again to run. How do I sort this?

cups does not start with the server. When I try to start from the terminal I get the error message
cupsd: Unable to read configuration file '/etc/cups/cupsd.conf' - exiting!
cupsd: Child exited with status 1!
The log files show nothing. cupsd.conf exists. It is user - root and group - root with permissions set at 0644.
My interpretation of this is that the program is not launching from either boot or terminal for a fundamental reason. I do not quite see what that reason is .

I've been trying to figure this out for longer than I care to admit. We upgraded our print server (sysadmin) to 64 bit lucid and that moved our cups server from 1.3.7 to 1.4.3. We have a remote server that is still 1.3.7 (printhost1) but version difference doesn't seem to be relevant to the problem.
If I'm on console on sysadmin and do an lpr to a printer on printhost1, everything is copacetic. However, If I'm on a host that specifies "ServerName sysadmin" in its "/etc/cups/client.conf" access_log on sysadmin shows:
172.16.10.52 - - [22/Mar/2011:11:11:40 -0500] "POST /printers/103_hp4250 HTTP/1.1" 200 306 Create-Job client-error-not-authorized
and error_log shows:
E [22/Mar/2011:11:11:40 -0500] Returning IPP client-error-not-authorized for Create-Job (ipp://localhost:631/printers/103_hp4250) from 172.16.10.52
We've been using this method of sharing printers between locations for years and years so it not working now is a surprise.
cupsd.conf on sysadmin looks like this and is as open as I can imagine:
ServerName sysadmin
ServerAlias *
ServerAdmin webmaster
FileDevice Yes
SystemGroup staff
LogLevel info
code....
Additional symptoms are that only printers locally defined on sysadmin show up when the client uses System>Administration>Printing in gnome. Same thing when you browse printers in windows on our samba domain controller that backends on CUPS.
I just know that it's something simple that's going to make me facepalm but I'm at a loss.

I can install VMware Server 2.0.1 on CentOS 5.3 (32-bit and 64-bit) perfectly. However, I can't access Server's web interface by going to port 8222 on the machine's IP address. When CentOS 5.3 (32 or 64-bit) is loading, I am greeted with this message "VM communication interface socket family: vsock: no version for "VMCIDatagram_Send" found: kernel tainted." I assume this is the reason why I can't access my Server through a web browser. How do I correct this? Is there a package I need to install on CentOS prior to installation of Server 2.0.1?
It's strange, because I can install 2.0.1 on Ubuntu Server 8.10 with absolutely no problem and access its web interface. So I think this might be a CentOS-specific issue I've uncovered.

I have installed Slackware 13 on one of the hard disks of my computer in order that I can get it working properly before changing over from 12.2.
My main problem is that I cannot get CUPS to change from 'Letter', which I presume is an American size, to A4, has anyone else had experience of this problem?

If I have only 1 physical WLAN interface, is there some hackery that can be done so that it can be a client of an existing access point and at the same time also act as an access point for other clients? I have an existing 802.11g ADSL router, and I'm going to be building an HTPC which will have 802.11n. My laptop also has 802.11n, but at the moment it only connects at 54Mbps because thats what the AP supports. I'd like to be able to have the HTPC be a client of my ADSL router, but have my laptop be a client of the HTPC, so copying files to it will be faster.

installed lenny and am trying to install brother dcp7010 again:
1) i can't start CUPS server with /etc/init.d/cups restart "file not found", there is a cups@ link in /etc/init.d.
2) when i install dcp7010 cupswrapper
dpkg -i cupswrapperDCP7010-2.0.1-2.i386.de
it ends with
" lpinfo: Verbindung zum Server nicht m�glich: Verbindungsaufbau abgelehnt
lpadmin: Verbindung zum Server nicht m�glich: Verbindungsaufbau abgelehnt"
(connection to server not possible, refused)
3)[URL] doesn't work.
4)foomatic-gui can't find the installed dcp7010 lpr-driver
brdcp7010lpr-2.0.1-1.i386.deb, (a couple of days ago it did)
This is frustrating because it worked in etch and worked for awhile in lenny. The dcp7010-scanner does work.

I have a multi-user machine with several network interfaces (Ethernet, if that matters). I wish to grant selected users, or groups, full access to selected network interfaces (including ability to adjust IP address and to bind to low ports, but *only* on those interfaces). It is important to me that an user/group does not such full control over other interfaces. Granting partial, or temporary, root permissions is OK; it's a friendly environment.How do I go about it?System: Linux 2.6.recent; usual Debian setup (can be adjusted if needed).
