Server :: Dansguardian Binary File Fails To Respond
May 18, 2010
There is this server running squid and dansguardian as proxy for the local network. Everything is working fine. But I have seen that from time to time the danguardian dies out and fails to respond to shutdown or restart commands. And this is because of the binary located at /usr/local/sbin named dansguardian goes empty. There are multiple instances and hence copying another named dansguardian.2 to dansguardian does it. And dansguardian works normally as it should. Looked into dmesg and /var/log/messages but nothing there. It was compiled and not installed from pre compiled binaries. And runs on CentOS5.4 Final.

I wanted to know how can I cross compile SMS SERVER TOOL for an embedded computer and make just one binary file for it or how can I change all of its default files places like its demon and object file and gather all of them to one directory to execute and use and run.let me explain it better for you : I have an embedded computer with Linux OS that its file system is read only and I can not add any file to /usr /lib and ..... and I can just mount a SD memory card to it and copy all of my programs to it and run them from there as you understand I have two choices to choose, first make one big binary file for each program that I am doing it now and it is not a suitable solution and the second is finding the way to change default place of shared object file of my program.now you tell me what can I do to solving this problem.

I'm trying to install Debian Squeeze (net install CD) on a PC with an EX100 wireless keyboard and mouse. The system starts the install without any problem, and the keyboard works up to the first blue menu on the Debian installer then stops - the system fails to respond to any key presses.
The mainboard of the system is an Asus M2N68-AM SE2, keyboard / mouse receiver is plugged into one of the USB ports on the back. I've had a look through the BIOS, there seems to be no option relating to the keyboard. Changing the PnP O/S option seems to make no difference. I've managed to install Ubuntu without problem on this system so I know the PC and keyboard are working fine.

I've been pulling my hair out and can't figure out what's wrong. I have dhcp, squid, and dansguardian all running on my server, but when I point a client to it for a proxy (192.168.1.15:8080) and try to get to a website, nothing happens and the connection times out. When I don't bother with the proxy, the client has no trouble getting to the internet. I've verified I can ping the server and gateway from both machines. And the services are running, no errors noted in the logs. Do I need to do any iptables or selinux changes?
My network is very basic, several clients on the same network as the server, connected to a verizon gateway. Local addresses are 192.168.1.x. The server is 192.168.1.15, gateway is 192.168.1.1.
I'm using:
* squid-7:3.1.8-1.fc12 (x86_64)
* dansguardian-2.10.1.1-3.fc12.x86_64
* Fedora 12
My squid config file:
Quote:
#
# Recommended minimum configuration:
#
acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1

I have around 9 squid proxy servers and going to deploy Dansguardian on all of them. But I feel managing individual copy/server would be an tedious job hence please let me know if any one aware of centralized management solution for Squid+Dansguardian? Or if not let me know if you are aware of any such other Open Source product.

I have squid running perfectly and I added MySQL Squid Access Report 2.1.4 and the reports works just fine. The problem its when I add a dansguardian content filter, from that moment the only IP address that appears on the report its the box itself (I have all running on the same box).
IPtables forward requests to port 8080 Dansguardian listening on port 8080 forwards to squid on port 3128 Squid on port 3128 to internet (Here I review the logs with MySar).
I know it is because the actual http request for Squid came from Dansguardian's IP address (its the job of the proxy). how to have the real IP address on the reports.

I would like to be able to get squid or dansguardian to authenticate a user account against active directory so that a users browsing activities can be logged.
I can find lots a very useful info on how to set up ntlm_auth etc, but all of these methods produce a pop up window when the user launches the browser.
I'm posting this thread because I would like to be able to authenicate, but without a pop up window. Is there a way of automatically carrying out this authentication so that the user is unaware of it.
We've previously attempted authenticating against an NT4 PDC, but the users worked out that they could use any user account on the network, not just the user that was logged in which kinda defeated the whole idea of logging the users activity.
My current setup is:
Windows 2003 AD
Windows XP Clients, soon to be converted to windows 7.
Fedora 11 running squid and dansguardian.

I've had Ubuntu 11.04 installed on my desktop since it's release. Up until an hour ago, it was working fine. I clicked on an update from the update manager, now booting into a graphical mode is completely broken, (the start-up load hangs at 'Check Battery State ... [0k]'). I restarted my computer, and booted into safe mode, and launched the terminal. This all works fine. I then typed :
Code: sudo gdm start into the command prompt, hoping that I would be able to start things manually. Instead, it spat out this: Code:
gdm-binary[230]: WARNING: Unable to load file '/etc/gdm/custom.conf'. No such file or directory.
gdm-binary[230]: WARNING: Unable to find users : no seat-id found.
gdm-binary[230]: WARNING: Gdm Display: display lasted 0.070467 seconds
The last line was printed about 8 times, with slightly different times, before it gave up and failed. Some information which might help, I have Gnome 2, Unity and KDE (not sure which version), installed. My graphics card is the GTX 275, and I have driver the Nvidia driver 275.21. So yeah, I think the update has gone and moved custom.conf somewhere, but I have no idea on how to fix it. I have a graphics programming assignment due on Friday and I would be eternally grateful if I could get this fixed well before then.

In a project I'm working on with a few other people, I got the task of writing an assembler. The last thing I do is convert the commands into a binary representation, and jam it into a file. Now one of my teammates said he'd like to be able to "reference" the code within another program. He said he'd be able to do this if the file I output is a Linux object file. I'm thinking it'd also work as an executable. Anyway, he said he'd like to be able to grab the file and reference the binary by address. I'm still fuzzy on this, and if you're confused with what I said here, please tell me so I can ask him for better details.Anyway, I'm aware that gcc can compile files to ".o", but that's only for C/C++, and my file is just binary. I'm also aware of "ld", but I haven't seen any use of it to help me. I'm happy to hear suggestions as to what I can do. If anything, I think I'll implement a few functions to grab the bits and hand them to him in an array or something.

I have a 2TB file-system and when the machine reboots it fails the fsck, halts and goes into maintenance mode.Stats: I have have RHEL 5, 2.6.18 kernel, the file-system is an ext3. The file-system is on an EMC AX4 connected with fiber channel HBA.So far my reading tells me this should work because under 2.6 4TB is OK. Any ideas why this fails?If I take it out of the fstab file and mount it manually the boot is OK and the file-system behaves well. I can change the fsck check option in the fstab to 0 but I don't think I should have too. Everything I read says that 2TB ext3 file-systems are OK.

Suddenly today during the start up the pc stopped to respond while doing a file system check...
I switch it off, restarted and everything seemed to be fine, i got the desktop without troubles.
Then i tried to boot from the live Key and run a fsck but it didn't work, i got some error like:
superblock could not be read....and at the end it says to run e2fsck
I did it and i got the same error...
So i restarted ubuntu and i decided to try:
And i got a blue screen where i selected the first option (something alike restart in normal way)
At the next restart i finally got the checking and it was fine! why i can't run fsck or e2fsck from live key

I have two servers, both running Ubuntu 11.04 Server. One is a web server, running only a LAMP stack and openssh-server. The other is running server daemons for TeamSpeak and Minecraft. Today, the game server just went down. I can access the LAN by using SSH to connect to the web server, and ping it from there. However, it won't respond to SSH or anything else. The server is a few kilometers from here, so I will be going there tomorrow.
This happened once before, probably about a month ago or something. That time, the web server was running just fine, but the game server was powered off. I thought there had been a power disruption, because when I checked the BIOS settings of the game server, it wasn't set to resume after AC power loss. The web server was set to do this, so it made sense that it would be up and running again after a brief power loss. There were also some news reports about power disruptions in my area.
The thing is, I changed the BIOS settings of the game server to make sure this wouldn't happen again. When I go there tomorrow, I will bring the server back up. However, I would like to know what caused this so that I may prevent it from occurring again. Is there a logfile or something that I can check tomorrow to find the problem?

I have Centos 5.4 installed on my server. Everything works perfect, however sometimes apache does not work properly. When I write my domain to browser it tries to reach the site, however it can't get any result. (There is no "browser couldn't find" error). The browser just tries to get the content.
When I login to my server with ssh using my domain name, there is no problem. (Named works.) When I give the "service httpd restart" command the problem disappears.I looked at httpd log files but there wasn't any problem at that time.I use the API's of the Facebook and Twitter, so there are many Curl requests are made with PHP. Could that be the reason?

I am trying to get a server to boot off the lan (pxe). I added a tftp server and tested it as operating successfully. I just plugged the pxe-server in and see the dhcp request/response as expected. The pxe-server then sends out an arp to the same address as the dhcp exchange, but the server never responds.
1. as the pxe-server already has info on the mac/ip-addr, why is it now sending another arp
2. why doesn't the server respond? I have most of my network setup the same way and the dhcp exchange is fine.
3. I'm guessing that the arp is triggered by the bootp exchange (next-server).
I do not have the server in the host table under that address.
127.0.0.1 localhost
127.0.1.1 ubuntu-desktop
192.168.5.101 windows1
Do I need to add 192.168.5.120 with a name to get arp to respond?

opensuse v11.3 I enabled a NFS server on a host, set up a couple of exports, opened the ports in the firewall. When I open the NFS Client on another host and select "Choose", there is popup that states "Scanning for hosts on this LAN...". Then it returns an error "No NFS server found on your network. ..." That's funny because I had previously mounted the two exported directories already by entering the server name manually. How do I get the NFS server to respond to an automated search?

I need to create a network boot from 1 laptop to another, with a crossover ethernet cable between them, no routers no nothing, my computer is supposed to be the server. I followed half dozen tutorials over the internet but I think my major problem is with the dhcp serverfollowed this tutorial[URL]but when the client boots it makes several dhcp requests but doesn't respondwireshark capture looks something like this until the client times out
Code:

I have two dhcp server (dhcp3) in the same network, this network is a link layer network so every host is seen as directly connected. The two servers have debian lenny and there are near 13 AP mikrotik to give connection to the XO laptops (from the project one laptop per child). This is for two public schools (each one with one server) that are connected via a p2p connection and each one provides internet for the school and outdoor too. The servers are also file servers, proxy, etc.
Each time a laptop asks for an IP, it sends a broadcast message and this petition gets to both servers, now a days the first server that reply is the one the laptop associate with. What I want to do is, knowing the bandwith use of the ADSL, the clients connected to the server, and the cost to the AP that the laptop associate with, decide wich is the best server to be connected to. What I want to achive is to balance the load and to decide the optimum connection, because now it could happen that one server is very loaded and the other is free. I tried to run dhcp with inetd and use tcp wrappers to invoke a script to check a condition before responding and, in case to be the best server, reply to the laptop, but i couldn't get the dhcp server to respond when I run it with inetd. here is my inetd.conf
bootps dgram udp wait root /usr/sbin/tcpd dhcpd3

I got a CentOS server setup as a dhcp server using dnsmasq. I followed this guide more or less: [URL] So, the problem seems to be concerning the DNS server on the clients. In windows I get the "limited connectivity" icon for the network, and when I select troubleshoot it says the DNS server does not respond. Issuing 'ipconfig /all' clearly shows the IP of the CentOS machine as the DNS server, which should be correct, yes?
ETH0 is working as WAN connection and that works great.. no problem with the WAN connection at all on the CentOS machine. ETH1 has the IP 192.168.0.1 and mask 255.255.255.0 When starting eth1, it sometimes says that it can't start eth1 because the IP 192.168.0.1 is already in use.. but that is most certainly not the case. Maybe there's some kind of issue here that messes with the DNS? What's mind boggling is that it works great on a linux machine (dhcp client) and on a windows xp machine. but it does not work on the windows 7 laptop and a vista laptop and a pda device.

I turned my home PC running Ubuntu 10.04 into a server, and so i am so lost, after reading like a 10-20 different guides and/or official docs, I am totally lost.
All I wanted was to create a custom 404 error page...i read about how people edited .htaccess files to customize error pages, i tried and failed also, editing apache2.conf, I got lost and i dont wanna mess up everything and also, how you're supposed to not touch either of those as its not how it should be done and instead you need to edit httpd.conf and i did and FAILED! again...
Also how do I make it so that I can make subdomain(s) on my site? and wth is a name server and where do I get one?
