I have a Printer which is attached to Linux System which is fedora 12. I have squid proxy server which is installed on CentOs 5. My squid works perfect. I am using it with wpad.
Now I can access the the cups page using
192.168.x.2:631 without proxy setting
But when I configure my browser with proxy setting 192.168.x.2:631 doesn't open. Due to this users are also not able to print. How to get cups working with squid
I've been trying to get CUPS working on a headless server, in order to share the printers connected to it with the rest of the network. The problem is that I can't add printers via the web interface, or rather, that I can log in, as it will not authorize my account. I've tried lppasswd, adding cupsys to the group 'shadow'(only to have the system tell me that there is no user called cupsys), and been editing the cupd.conf for hours. On top of all tha, I can't even get to the web-interface without running "/etc/init.d/cups restart"!

I just installed CentOS 5.3 on Compaq desktop PC with HP laser jet 2100 attached to parallel port. The PC is connected to LAN with 2 other PCs running Fedora. I configured the HP printer as a shared CUPS printer and I was able to detect the printer from the other PCs running Fedora but I can't print test page from the other PCs.
P.S. I opened up port 513 and 631 for both UDP and TCP on print server PC and cups-lpd service is running on it.
I want to use squid Proxy to ask username password to user for internet usage and if username password not correct squid stops user access.I use following installation commands and configuration but still squid not asking for username password, and I can use Internet browsing by defining proxy in my client proxy.I use following installataion commands one by one but non of them works, and configure squid to use ncsa_auth../configure --enable-delay-pools --enable-linux-netfilter --enable-arp-acl --disable-ident-lookups --enable-snmp --enable-removal-policies
then I use
./configure --enable-delay-pools --enable-linux-netfilter --enable-arp-acl --disable-ident-lookups --enable-snmp --enable-removal-policies --enable-basic-auth-helpers
then I use
./configure --enable-delay-pools --enable-linux-netfilter --enable-arp-acl --disable-ident-lookups --enable-snmp --enable-removal-policies --enable-basic-auth-helpers=NCSA
with following squid.conf configuration one by one.
htpasswd /usr/local/squid/etc/passwd testuser
New password:
Re-type new password:

No error received in access.log or /var/logs/messages files, nor on client screen, client still using internet browsing without asking username password by squid,
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

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 have configured a squid proxy server with @2 eth in different network subnet and with site blocking and extn file download blocking. One eth0 for office wired network and another eth1 is for office wireless network for laptop use for guest and visitors.

The above website is perfectly working with Gateway configuration in TCP/IP properties in Network Configuration in MS Windows XP computers but through squid proxy its not working.

I'm beginning to think linux actually isn't capable of sharing files and printers with anything. I've been trying to get my LMDE to share files and be able to retrieve files from the other windows PCs I have on my wireless network. I would also like to share the printer I have connected to my LMDE install with those same computers. In short how is this done because I pulling my hair out trying to figure out whats wrong.
As I understand it sharing the printer should be easier than sharing files. Its done by CUPS? Anyway I've enabled sharing in the printing, and in the "server settings" windows ticked "publish shared printers connected to this system". That doesn't work. Windows can't find it. Samba on the other hand is even worse. Edit the smb.conf? Nice way of making things complicated!
My printer is a HP laserjet 4 Plus. It used to work with the gutenprint drivers pretty much since always.I don't know when it broke, because I don't use it that often. I have tried with the generic postscript driver, with the gutenprint driver, with the j4dith driver and with the hplib driver. Basically, what happens is that all jobs never finish processing in the queue. On the other hand cups-pdf still works.

I am trying to set up a print server here on a Squeeze system using the stock debian CUPS package. It seems that since Apple has bought this package, it has caused me nothing but grief. I have set up two different USB printers with raw print queues, and every time I send a print job to either of them, the job disappears into thin air, with no error output. In fact, when I look at the queue, it says the job was completed successfully. I look at the logs, and there is no output indicating any issues. Just for kicks, I reconfigured one of the printers to use a linux driver, and it printed just fine (a little slow, but fine). I set it back to raw, and the jobs disappear again into oblivion.
I have done this many times in the past, and never had any issues -- I even had this very same printer set up that way about a year ago, and it worked great. The only noteworthy thing that seems to have changed is that there are no longer any files called "mime.types" and "mime.convs". It seems they have been replaced by "raw.types" and "raw.convs". The contents of these two files are as follows:
raw.types: application/octet-stream
i'm using a Lexmark Pro 905 printer , it's a local printer with Ethernet connection to the pc.I installed the driver and this used to work on 11.2, now with openSUSE 11.3 it's not working.

I was using Red Hat 7.3 forever and decided it was time for a change. I went to Fedora 10 but it was really buggy. CentOS 5.2 is VERY stable.Here is my problem.The server is command line only -- I tend to hate GUI"S.I setup Samba no problem disabling the ports needed through the firewall and that was straightforward.CUPS is a nightmare for me since CentOS locks down the cupsd.conf and then the firewall does its thing. I allowed port 631 through the firewall but then got lost on the cupsd.conf. It's been too long and the old redhat one won't work with CentOS (not surprising since it's a VERY old system) straight-forward CUPS tutorial for a command line interface. I just need it to be:
a) do this
b) do that
I have been using Opensuse since 11.0, and I never had any problems with the setup of CUPS printing (university based). Now for the first time, after many months of flawless printing using 11.2, after installing 11.3 the printing has stopped working. I use the same method: Print via print server machine -> CUPS server (IPP) and I test the connection. In my 11.2 it shows "OK", in 11.3 (I also tried with firewall off) I am getting the following (I have substituted the actual values with xxx for privacy).

My printer no longer prints anything with exception to the TestPrint page.Any other job I give it, it says is "completed" in the queue, though nothing has printed. Installed cups again, after a complete removal. No change. Heres what troubleshooting gave me:

after looking at this thread [URL]... i found out that my printer is no longer working with the latest CUPS package (in -Current). I tried to delete the printer and re-adding it again with the same driver, but it failed with an error message: Bad device-uri "cnij_usb:/dev/usb/lp0"! I have tried to use the driver provided by Canon or by the automatic detection by CUPS, but it ended with the same results

How to I add a root users to access the 127.0.0.1:631 interface for CUPS?
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.....
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 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.

Here is my query:
Squid document says that Squid accepts only HTTP requests but speaks FTP on the server side when FTP object are requested.
We call Squid HTTP and FTP caching proxy server. Does it also caches FTP contents? Is it possible to configure FTP clients to use Squid cache? When we make an FTP request to an FTP site via Squid will it be bypassed?
I have a proxy server (squid-3) that I would like to setup Dansguardian to do additional web filtering.
The system:
Ubuntu 10.10 - all updates as of today
Dansguardian - 2.10.1.1-2ubuntu0.1 (latest update)
Squid3 - latest update (not squid 2.7)
Webmin - 1.530 (all updates)
Webmin dansguardian module - 0.7.1
Ok - I have all of the above installed. When I go to the DG module page in Webmin, I get the following:
Warning - the version of DansGuardian you have is not supported by this Webmin module version
Webmin Module Version 0.7.1 supports DG version 2.10 (& 2.9)
Currently installed DG version
This obviously makes no sense, since I am running DG version 2.10.1...
PS. I have squid installed, but not configured (still tinkering) - could this be the problem? That squid needs to be running for DG to work?
I want to make a transparent squid proxy server in centos. The squid proxy version is 2.6 stable. I made a normal squid server but want to make it transparent so that users do not need to enter the proxy settings in web browser. Even i searched about this on google but not getting it properly.I have two lan cards on centos system. ETH1 used for LAN and ETH2 used for WAN. And in this squid.conf i written "http_port 172.16.31.1:3128 transparent" and i also added a rule in iptables which is "iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128" but still i have to enter proxy settings at client's web browser to use internet
