Server :: Conditional (on Ip Address) /etc/issue.net Possible?
May 27, 2010
I'm running Debian with openssh 1:5.1p1-5 and I've got an operational and legal /etc/issue.net but I'd like to make it depend on the incoming IP address. To be more specific, I'd like to achieve that no banner is shown when logging in from my company's IP range(s) or when logging in from home, but any unknown address (potential intruder) should be confronted with our legal warning.Is this at all possible?The server is located off-site and only has one ethernet device active (i.e. I cannot say eth0 is external, eth1 is internal)
I hv Cent OS 5.3 installed as server. I hv a network of approx 100 desktops and laptops. For a security purpose i want to block certain laptops from gaining a the network access using dhcp. Can we block the ip address leasing if a specific MAC address request for a ip lease?
If I give "ifconfig" in my laptop I get eth0,lo,wlan0.In that where do I find my Ip address in Ubuntu in 10.04. In eth0 I dont find inet address.Where can I find it?

I pride myself on at least trying to help myself before I ask, but I've been staring at this a long time, I'm just not getting any traction.I've literally got 3 linux references on my desk right now that say that I should be able to use if conditionals, for example
[ -d FILE ]True if FILE exists and is a directory. [ -e FILE ]True if FILE exists. [ -f FILE ]True if FILE exists and is a regular file.
I am facing the following issue. My application runs perfectly in red hat linux(32bit, 64bit physical m/c and 32 bit vmWare m/c) and in one version of centOS(32bit physical m/c - don't remember the version:Sorry). However when I am running the same application in CentOS 5.4 (64bit version) I face the following issues -
a. the application gets stuck in the conditional wait even though the signal is sent after the application has moved to conditional wait. b. vsftpd service start fails from within the application even though the service starts and stops peroperly from console.

I cannot seem to get if else statements to work. if $choice == Dog then i want it to say "you selected Dog" The variable choice has the value Dog in it as proved at the end by echo "yes $choice is $choice" following the error Code: ./test.sh: 37: [$choice: not found How do i get the conditional statement to work? What's wrong here? This is the full script:
I am using "if" to force a word under the condition that the first letter of that word must be a letter of the alphabet, regardless of capitalization, using the " "" != "" " syntax.
Like so:
Code: if [[ "$interface" != "WHAT DO I PUT HERE?" ]] ; then echo "Invalid input" exit 1 fi

I'm having a problem whereby I'm able to send mail to a mailbox from several different email addresses and SMTP servers (gmail, RoadRunner broadband), but I'm unable to send mail to the same address from one particular account, the SMTP server for which runs on a mediaTemple (dv) 3.0 box with CentOS 5 Final.I've spent a full workday on the forums, trying to troubleshoot the issue, and I'm running out of ideas.The server on which I'm having the mail processing problem is a mediaTemple (ve) running Ubuntu 10.04 x64 (Linux 2.6.18-028stab070.7 #1 SMP Fri Oct 1 13:53:00 MSD 2010 x86_64 GNU/Linux), with ISPConfig 3. Here's how I setup the mail-related aspects of the Ubuntu box:
One of our client having issue with the qmail. The issue is if any one send email to abc@ourdomain.com (abc@ourdomain.com the email address which is not exist) it should send failure notification i.e."email does not exist" to the sender. The qmail server is not notifying that email address does not exist.
especially to ubuntu server 8.04 because it doesnt use a GUI. Now my question is on how to insert IP address in configuring DNS server using bind9. Actually i'm using this guideBut i m not sure on how to insert IP addresses on the primary master and secondary master. Should I insert the Ip address that i found when i type ifconfig ? or Should I assign a new IP address.I have set up a webserver, DNS server, File server and mail server on a virtual box. For now, at first, im working with the DNS server or should I work with the web server first?what should I do?

i recently built a server running openSUSE. when trying to connect via ssh or telnet or ftp etc etc on my LAN, everything is ok. i just recently found out that when i try to connect to my world ip address {the ip address everyone else sees,] it does not work. i recently came to the conclusion that since the server i built is running off a router connected to another computer, my world ip is the same as that one, and there is no server built on that computer. is there a way i can connect to the computer that is running the server on my network from outside my network i.e from somewhere else?
I'm trying to run a server, and want to get my IP address but when I run ifconfig, it shows my inet address as 10.0.1.9/10.0.1.4 which, if I recall correctly, is an internal address... my friends can't connect to the server on those ip addresses. My box is wired to the internet, no router, so there's no firewall or router that could be stopping it. Am I doing something wrong with a command, (reading wrong number, etc), or is it a system problem?
I have specified Primary DNS address in Network Manager's DNS tab and saved those settings. But when I restart my PC, Primary DNS address will go blank. How can I save this address premanently?

Quite often I get some difficulties for the clients to get an IP address from the dhcp server. If I look at the server logs, it looks like the server sees the requests and sends and answer:
