Slackware :: Which IP Address To Use When I List Machine Name In /etc/hosts?
Jul 21, 2010
1) I'm not sure which IP address to use when I list my machine name in /etc/hosts, particularly after reading:
Quote:
By the w]ay, Arnt Gulbrandsen <agulbra@nvg.unit.no> says that 127.0.0.1 # should NEVER be named with the name of the machine. It causes problems # for some (stupid) programs, irc and reputedly talk. :^)
Here's what I have now:
Code:
root@eagleswing:~# hostname
eagleswing
root@eagleswing:~# cat /etc/HOSTNAME
eagleswing.5binc
[Code]...
I'm not certain how to include my router in /etc/hosts so I can use it to link my PCs as stated above. I was thinking of writing (see above link):
192.168.2.1 localbelkin Will this work & is it proper?
3) Do I need to make use of any other IP addresses at this link? What are the WAN IP & Default Gateway addresses used for? I am going to be serving documents & running scripts on Apache.

I'm trying to use ssh-keyscan to get some known_host file population going on, but I have a ton of hosts I want to scan, all with multiple aliases in /etc/hosts. Is there a way to use my current /etc/hosts file to do an ssh-keyscan instead of making a special list of hosts that (from what I've read) ssh-keyscan needs?

I just changed my CentOS server from DHCP to static IP address. After the change, I cannot ping other hosts on the same subnet. (I can ping the CentOS itself).The IP address of CentOS is 192.168.0.202.After pinging 192.168.0.106 (106 is on and other host can ping it), arp -a shows? (192.168.0.106) at <incomplete> on eth0 It looks ARP cannot resolve MAC address of hosts 192.168.0.106.

What is the (officially) proper way to configure Apache so that a given IP address can have two or more virtual host names, each going to different distinct configurations (e.g. with different DocumentRoot, Alias, etc), and also do this for the IP address so that it goes to a designated configuration rather than defaulting to the first or a random host name?
Apache documentation does not appear to address this. If so, it has it hidden in a non-obvious place.

I have setup Denyhosts to run on my server, and have been using it succesfully for the last few weeks, to allow me to ssh into my server from my home dev machine.
This morning, I accidentally typed my password incorrectly three times - and ended up being locked out of the system (tghat was ok, because that was what was supposed to happen). I logged into the server via another way and took the following actions (in the order given)
/etc/init.d/ssh stop
/etc/init.d/denyhosts stop
removed my IP address from /etc/hosts.deny
/etc/init.d/ssh start

The facts are as follows:
1. I have at work a regular LAN with many PCs, each with a DNS-registered public IP. Therefore I am able to address each of these PCs by their fully-qualified names and, for instance, initiate ssh sessions to any of these computers just by typing "ssh <name_of_machine>" from a terminal.
2. Within the aforementioned LAN I have just created a private network with some clients, which access the LAN through a router (a D-link DIR-825). We have created this private network for many reasons, but most importantly because we need to guarantee that the hosts in this network will remain networked among them even if the LAN goes down for any reason (which unfortunately happens often). But we still need to have access to the hosts in the private network from the LAN.
3. I am able to define port forwarding rules in the router in order to access certain services on the private network's clients. For example. I am able to access (by ssh) hosts "H1" and "H2" on the private network from a client on the LAN by defining rules for forwarding ports "P1" and "P2" on the router's public IP to TCP port 22 on the private IPs of "H1" and "H2", respectively. Then I would access each of these hosts from the LAN by using:
>ssh -p P1 [ip.address.of.router] (for accessing H1) and >ssh -p P2 [ip.address.of.router] (for accessing H2)
4. The problem with the port forwarding approach is that it is not easily scalable. For instance, If I wanted to enable ssh access to each host in the private network, I would have to define a port forwarding rule for each machine, and then REMEMBER all these port rules when initiating a ssh session from the LAN in order to point to the right host. And the problem gets worse when considering more services in addition to ssh.
5. The ideal solution would be to be have a means for addressing each host in the private network individually, in much the same way in which I address the hosts in the LAN (which have DNS-registered names). For instance, in order to access hosts H1 and H2 as in the previous example, i would like to be able to just type
>ssh [name_of_host_H1] (for accessing H1) and >ssh [name_of_host_H2] (for accessing H2)
The bottom line:
I guess I can say that what I need is some kind of combined DNS-ing and routing that allows me to communicate with the hosts in the private network from outside of it in a transparent way.
The question is: what are any possible solutions for accomplishing this? I have searched the web and found stuff about things like VPNs, reverse-proxies and NAT servers, but I really can't understand if any of these could serve to solve my problem (BTW, isn't my router doing some sort of NAT-ing already? could I just add some DNS-ing in some way?)

I have DDNS configured and working for dynamic addresses, but it's not quite right for static addresses yet. The DHCP server assigns the static address, but it doesn't update the DNS sever with the associated host name. Which means I have to use the IP address when accessing the host instead of the host name. How can I get the DHCP server to update the DNS with the host name associated with the fixed-address?Here is my current dhcpd.conf.
Code:
ddns-update-style interim;
ignore client-updates;

I am trying to run two web servers (Virtual Hosts) on a single Linux Centos 5.5 box with a single IP address 192.168.0.182. I did all the pre-installation requirements such yum install mysql, yum install mysqladmin, service httpd start, service mysqld start etc etc.In /var/www/html directory, I have two folder called server1 and server2. These two folders have the necessary web server php script files and folders. I opened the browser and managed to install the script on one web server successfully. When I put the IP address 192.168.0.182 on the browser address bar, the page loads without any problem. Now I would like to be able to install the other web server script and I don't know how to?Here is my httpd configuration;
<VirtualHost *>
DocumentRoot /var/www/html/server1
ServerName development.mysite.com

Is there some way that I can use apache/iptables to serve both of my servers through the same basic domain? I'm not talking about VirtualHosts either, I don't believe ( despite the fact that's all I can find anything to read about on Google when searching for this ).
Anyway, the problem is that I have a TorrentFlux php torrent-client that I run so I can add stuff to the download when I'm not around. I don't want to put this on my regular webpage server because there's just not enough diskspace in that machine. On the other hand, I don't want to replace that server all-together because the other machine is my desktop and would not make a reliable host.
So my idea was that there could be some way to have the apache2 server on my dedicated server redirect a subdirectory in its webroot to the webroot of my desktop's TorrentFlux server, but over standard HTTP ports so that it is more like the server is serving up the content of my desktop server through its HTTP service, instead of simply redirecting.
The reason I want to do this is because so far I have to use the TorrentFlux server on a nonstandard port so my dedicated server can still host its own things on port 80, but I've been running into several situations where the browsers I want to use do not support the nonstandard port such as with some instances of IE or the browser on my BlackBerry.
Anyway, I'm not looking for a step by step or anything ( though it couldn't hurt ) but I just need some ideas on what I could search for to get some better ideas. There's probably some term for what I want to do I'm not even aware of that would help me greatly.
Runnining Ubuntu 7.04 and apache 2.2.4 along with shorewall 4.0 as my routing/firewall software.

I can reach other hosts by means of their global addresses by either the IP address or hostname (that has the global address). What I want to (also) do is have a hostname that references the IPv6 link local IP address (an AAAA record in DNS, or just the fe80::<whatever> address in /etc/hosts) and use that host name in commands to access that host. The problem is, an interface ID is needed when making such a reference.
It sure looks like the programs just pass the host name string on to the resolver library, which does not understand the significance of the '%' even though it could find and see that the name preceding the '%' is consistent with that being an IPv6 link local address (e.g. the logic could have been "split at first % and see if preceeding name is found as a link local address and accept that if so, or ignore the split otherwise" ... but it isn't). Is there a different syntax for this ... or was it overlooked in the design of programming around IPv6?I want to be able to address a host by its link local address, while still using a mnemonic instead of having to type the IPv6 address.

I'm not sure if this is best done in Perl or Bash. I'm thinking surely someone else has created something close to what I'm looking for. The results of the script would be that someone would kick off "linux_hosts.sh" r whatever you want to call it, then a top "folder" of options (with hosts contained within each of these top menu choices), then, based on which number corresponds to that top level, they're presented with a set of linux hosts that are relevant to that top level name. Example:
$ linux_hosts.sh
1. VMware hosts 4. Private Domain
2. ESX servers 5. Red Hat boxes

I am trying to configure Apache to handle virtual hosts. For this I un-commented the line in httpd.conf that say
Include /etc/httpd/extra/httpd-vhosts.conf
Then I included the following in httpd-vhosts.conf:
<VirtualHost *:80>
<Directory /var/www/git.localhost/gitorious/public>
Options FollowSymLinks
AllowOverride None
Order allow, deny
Allow from All .....

Well, as many proxy applications, GNOME Network Proxy Preferences only allow to ignore hosts. What I want to do is exactly the opposite. I only want to use the proxy for few sites. Is it possible to define only the allowed hosts in any way?
PS: I know FoxyProxy add-on for Firefox does this, but 1)I don't use Firefox and 2)I want the proxy settings system wide not only for browser.

I'm just an undergrad with duck tape and google searches to hold this place together. Anyways on to my question. Where I work, we have a tape library but no way to configure it, the backup software simply talks to the robot to load and unload tapes. There is a network port on the library and I do have the software, but have been running into problems getting access. I was wondering, is there a way to determine the ip address of this machine by plugging in a cross over cable with a laptop and scanning it? What tools could I use to do this?

My ISP can give me up to 5 ip addresses. Is it possible to "forward" one of them to a machine to get rid of nat? I was thinking of "forwarding" one public ip to my machine and let the rest of the network share one ip using nat.

I use Ubuntu with Evolution here at work, and we have an Exchange server. can I somehow suck up all of the addresses in the global address list and somehow save them locally and import them to Evolution? Since I can't "link" to the global list it would at least be handy for me to utilize locally.

in light of the current kernel flaw being circulated:[URL]...and the solution being proposed here:[URL].. How do I know if I have any 32 bit binaries running on my machine: Ubuntu: 10.04 64 bit
I generally always install most of my apps through the repo's but I **may** have installed some apps from source code or other methods. So how can I list any 32 bit binaries running on my machine before implementing the solution cited in the second link?

I'm elated when I see software download pages that include a binary Slackware package.wrt KVIrc, their Slackware package is at the top of their list of binaries.They've got an rpm too, but it's SuSE, not Redhat - I found that to be pretty kewl too.I wonder if they're Slackers... hm...Well, that having been said, there's also a SlackBuild for it at the repository.I'm going to give this client a spin and see how I like it.Here's the URL: http://www.kvirc.net/?id=releases&pl...=4.0.2&lang=enUPDATE: The mirrors I checked are reporting 404 errors... bummer.
