Ubuntu Servers :: Install And Configure Denyhosts On 10.04 Server?
May 3, 2010
I've been running denyhosts on Ubuntu 8.04 servers without any problems using the how-to found hereow that I have a new Ubuntu 10.04 server running, I thought I would just install denyhosts from the Ubuntu repository not realizing that the paths and filenames of the install are different from the how-to I am used to using.I figured out what the name of the new denyhosts config file is (at least new to me) and the new location, but I'm not sure about the "allowed-hosts" config file.Does anybody know where the new path for this file is and whether the filename is still the same?

I am trying to install and configure LTSP on a server for a HP thin client to boot off. The version of Ubuntu that I am using is 11.04 x86 and it is a fresh install on a dual core system with 2GB RAM. I followed a guide which comprised of these commands.
sudo apt-get install ltsp-server-standalone openssh-server sudo ltsp-build-client or if your on a 64-bit system with 32-bit machines do sudo ltsp-build-client arch i386 for editing the servers IP values use /etc/ltsp/dhcpd.conf after that you need to restart DHCP server sudo /etc/init.d/dhcp3-server restart
and update sshkeys -sudo ltsp-update-sshkeys and if you updated dhcpd.conf then you need to update you image also by typing in terminal ltsp-update-image
Everything seemed to install as it should but when I try to boot from the thin client it just times out and says no DHCP or proxy invites received. I turned DHCP off on the router and even tried another router, but I still get nothing. I am at a bit of a loose end and I hope someone on here can point me in the right direction of where I am going wrong.

I am trying to install Ubuntu server edition on an old HP XT963 that recently came into my possession. I mainly just wanted to use it as a home file server and print server. I have been running ubuntu desktop on my laptop for a little under a year, but this is my first go at the server edition.
While ubuntu was installing it said "network autoconfiguration failed," I hit continue, thinking I could figure out how to configure it later. After lots of googling I still haven't figured out what exactly is wrong.
Code:
auto lo
iface lo inet loopack
after googling around I made it look like:
[Code]...
I would like to provide more information such as ifconfig and any other commands but I'm not exactly sure how I would do that without being able to copy/paste. I guess I would have the command dump the output to a file, but I'm not familiar with the -options this being my first time CLI-only.

So I installed denyhosts on my system and I ssh to it fine. Then all of a sudden I got an email saying my ip was added to the /etc/hosts.deny file.I have no clue why. I did not fail the login. So I had an open session and put it in the /etc/hosts.allow file and tried to ssh back in no problem.Then I logged out and all of a sudden I got the email saying my ip was added to the hosts.deny again. Now I am kicked out of the system..
I am guessing I cannot get back in until I get to the console and remove it. I can power on and off the system remotely but I enabled the chkconfig denyhosts on option so it starts on reboot. No remote console is setup.So it looks like I am hozed until I can get to the console, bummer as I was trying to set up a spacewalk server on it. I cannot get to the console for a few days so if anyone has ideas how I can get back in let me know. But denyhosts seems to be working as designed.
This was a default install I did not configure anything funky. Just changed the email to root and started it.I thought about changing my client IP but that wont work as I only have ssh passed on my router to that IP so if I change the client IP I wont get into my routing machine.I think i answered my own question but just thought I would askI guess my real question is why would denyhosts block my IP when the login did not fail and how do i configure it so this does not happen again.

I have used for a long time Filezilla FTP Server on a windows server, for multiple users in my company around the country.Lately the windows box died and I said let's try ubuntu server 9.10. I configured to my best as a Samba file server and from a speed point of view it works even faster than the Winbox.Now getting to FTP setup, I had the following problem when setting vsftpd.How can I enable more directories for the user, each with its own rights. By example, in Filezilla I had two folders for each user: one was a specific folder in which he could also write, and the other was read-only. They were setup with aliases, so that when user login, he sees one continous list of folders.I tried with symlink, but couldn't do it. Also I searched through the man page but also did not find something specific for this task I would appreciate any help you guys could give me in order to solve this issue, using the best practice for vsftpd. Also note that I am open to other FTP servers as well.

Starting with Ubuntu Server 9.04, when I log in at times the OS smartly reports the number of updates available. I have a couple of questions of how to extend this functionality:
1) How could I back-port that functionality to 8.04 servers? Does that happen somewhere in the /etc/cron.daily/apt script? (Just the checking on # of packages needing updates, does not need to appear on the login screen.)
2) Then with that information, if the number >0 then use mailx to send admins an email. Since 9.04 and higher already do the first item, then in my mind #2 is the only thing needed for 9.04 and higher servers, and #1 is also needed for 8.04 boxes.

This is my first post to the forum
I've recently migrated my office PCs to ubuntu. My server doesn't server any big purpose but to provide Internet Connection to the rest of the nodes. Things were quite easier during the windows era using ICS.
Even in Ubuntu we were able to do it using the "shared network" option, simple & straight forward. But things got complicated only after installing "squid". Needless to say it brought in a lot of add ons as far as the http proxy serving is concerned & we are enjoying a better internet(http only) connectivity without any doubt. But we are not able to use our email clients, MS Outlook or Thunderbird
But to best of my knowledge squid strictly is a http proxy hence doesn't support handling requests on ports other than 80. (465 & 995 in my case)
Now I have two queries, 1. Can "Squid" really be used to do what I want here??? using iptables, port forwarding or any other mean
& 2. Can any one suggest a good pop3/imap proxy as good as squid is.

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

I am a newbie to linux and running ubuntu server 10.10 (no gui), I had it configured with a fixed ip address and all was fine till I changed internet poroviders and got issued with a new router.
I am trying to configure the server to reflect the new settings of the new service provider. here are the contents of /etc/network/interfaces
Code:
auto eth0
iface eth0 inet static
address 192.168.15.52
netmask 255.255.255.128
gateway 192.168.15.1
Just so I got this right can someone tell me if I am right here. address is the IP I wish to give to my server statically. and gateway is the ip of the router. When I try to ping the router I get
Code:
Ping 192.168.15.1 (192.168.15.1) 56(84) bytes of data.
From 192.168.15.1 icmp_seq=1 Destrination Host unreachable
When I try to ping the internet i get :
[Code]...
Is there anyone that can shed some light on where my problem may be. As i said before I got the new router I had been working with the server no problem.

After struggling with a bad LP cable I have finally proven that the cable, printer and port all work. I booted in to another OS and was able to finally print. Now, I'm trying to get server 10.4 to recognize the printer and then I want to configure CUPs so I can run this machine as a headless print server, among other things.
Apache is running as I managed to get nagios to run and I can pull it up from another PC via a browser.
sshd is running as I'm logged in from another PC via ssh.
Problem number 1 is how do I install a driver for an NEC Superscript 870 printer? As it is lpstat returnes with :
karl@zeus:/etc/cups$ lpstat -t
scheduler is not running
no system default destination
Once I am able to print then I need to print to the server from other hosts on the network.
