I have a home server that I built recently and I have been looking into things I can make it do, and one idea that came up was software to manage incoming calls. The main thing I want is something that can block numbers, but it would also be nice if it could record calls or broadcast the caller id over my wireless network somehow. I've tried Googling around, but I really didn't find much.

I have a SSH server on Ubuntu 10.04 running behind a NAT. I have done the port-forwarding at the router. However say for example I want to restrict people connecting to the SSH server by country IP's. When I configure ufw with the following rule it still lets the IPs that are restricted through. Any idea why
sudo ufw allow from xxx.xxx.xxx.xxx/24 to any port 2556

View 2 Replies View RelatedSo first off, it probably seems this question has been asked thousands of times before. but I did do a search, mostly archived posts that ended up being something other than a true ip blocking of the port. [URL]..
So my port 80 is truly blocked. Ive tried setting up the port forwarding on my router, Ive tried manually allowing all traffic on port 80 through ip tables. Ive even dabbled with setting up something like openDNS to see So far nothing, Im only available on my local network.
There has to be some way to do a redirect though. even something as simple as an htaccess file redirecting [URL].. xxxx (the space is there to avoid my url being interrupted by a smiley
not blocking sites
Code:
dbhome /var/lib/squidguard/db
logdir /var/log/squid
dest block {
domainlist block/domains
[Code]....
under db I created a directory block where I created a domain file and a urls file dosen't seem to be working
I have Ubuntu Server (x64) installed on my box with Apache2 and Squid. For awahile port 80 (http) was fine, I could update packages and use wget. Then one random day port 80 became blocked for incoming traffic. I couldn't use apt-get and had to change to an ftp mirror to update. Also wget is not working.

Currently I'm using Sip Communicator as the softphone, but I tried x-lite 3.0 on Windows too. The phone works has like a regular headset, I can hear and speak without a problem. However I cannot take full advantage of the phone, since the phone keyboard only work in Skype through the Skype Portal software that come bundle with the phone (Windows only). Is there a driver that I can use in order to be possible to dial using the phone and display the called ID with a regular softphone?

View 9 Replies View RelatedMy IP has been blocked by Composite Blocking List for " IP Address 207 is listed in the CBL. It appears to be infected with a spam sending trojan or proxy. It was last detected at 2011-01-02 11:00 GMT (+/- 30 minutes), approximately 1 days, 3 hours, 29 minutes ago. It has been relisted following a previous removal at 2010-12-30 17:15 GMT (3 days, 21 hours, 2 minutes ago)"
How do I find this "trojan" and remove it???? I have a network of 6 computers right now, 5 are running Ubuntu (3 server and 2 Desktop versions) and one windows computer. I have run a virus scan in the windows computer and found nothing. How can I scan a linux computer for a virus?
I recently upgraded a couple of my systems from 8.04 LTS to 10.04 LTS. I had no issues with nfs prior to the upgrade. After the upgrade I am occasionally seeing the following messages:
mspfiles being the share name.
This never used to happen on 8.04. Generally the error "Socket operation on non-socket" points to a coding error. Could this be a bug in the kernel? Has anyone else come across this?
The only other recent reference that I found to the same errors was in this comment on the OpenSUSE bugtracker: [url]
It seems as though it is handling loss of connectivity less gracefully than it did before.
I can't really upgrade any more of my servers until this is fixed as we are heavily dependant on nfs.
For system calls, is blocking or non-blocking default in C? Simple question, just am not seeing the answer super quickly.
View 4 Replies View RelatedI have a device that is working on modbus protocol andI have written a small program(with block TCP read method ) to read its registers via modbus protocol.my program is working very well but except those times that I unplug the Ethernet cable or turning off the modbus gateway during programs work.at this time my program stops on recv system call (if it reach this system call exacly when I unplug Ethernet cable or turning off the modbus gateway during programs work).I changed my source to work in nonblock TCP method, at this time with the same situation my program does not stop/block on recv system call but after pluging back the Ethernet cable or resuming the connectivity situation back it reads data incorrectly .this is my code:Quote:

In practice I have a script that call a java program that call a linux system command. The script if I run it, from a shell functions well,so it is not a java problem. The problem come out when i put this script in a crontab schedulation. The result in this case is that java do not execute the system command. I think it depends on crontab

Thinking the problem might be due to iptables I tried the following command as recommended by a book I found on google:
Code:
sudo iptables -A INPUT -i wlan0 -f -j ACCEPT
didn't help so tried disabling the firewall - still getting the error
Both machines are running FC11 - should i be using nfs4?
My question is quite simple:What are type of applications where socket in blocking mode can be used ?
And where non-blocking mode to be used ??
TCP is blocking by default.

Since I 'd read how to use ufw I created a deny rule for port 139. After a second scan with Nmap it still said that port 139 was open as shown below.

I'm trying to use VNC on my headless desktop server that's running lucid, but I can only use SSH because a pop asking me to unlock the keyring shows up every time I try to use VNC. I don't have a monitor for that desktop, so I was wondering, is there any way to remove the keyring/to automatically unlock it during autologin? I don't remember what a site I found it on, but I used this to remove my keyring yesterday. It's no longer working today.

I might be misunderstanding the log but it looks like UFW is blocking connections. I want to allow all incoming and outgoing. I guess what I'm saying is that the servers on my computer will open ports but all other ports should respond with closed just like a default Ubuntu install. Trying to use UFW to monitor connections without really doing any firewalling.
