Does anybody know any useful free software for SMS Gateway (like OZEKI software under windows) for linux that receives sms via GSM modem convert it to mail and/or fax and visa versa and has web base configuration GUI?
View 3 RepliesI am wanting a computer with an external dialup modem (ppp0 modem through a com port /dev/ttys1) to act as a gateway to the internet, forwarding internet traffic through ethernet (eth0 is set to static 192.168.2.2) to a router (the router is 192.168.2.1) where it will be broadcast to other wireless computers like my laptop (192.168.2.3). I've had this setup until recently when the gateway computer (the one with the modem) died. Now I'm replacing that machine with another box and an install of Ubuntu 10.10 but so far things aren't working for me.
Success so far:I have dialup access working on the new box. Took me a while to work out the configuration for getting dialup working, though the IP address is Dynamic (or it won't stay connected), "Check carrier line" is off, and "Ignore Terminal Strings (stupid mode)" is on in order to successfully connect and stay connected to my ISP. I also had to make my normal (non-root) user "lancer" a member of the "pid" group (the reboot) in order to use gnome-ppp as non-root. The laptop (192.168.2.3) is successfully connecting to the router (192.168.2.1) as I can see the router configuration page when I type http://192.168.2.1 into the laptop's web browser. This setup is unchanged from how I had it before when this was previously working and I don't want to change how the router itself is set up. What I want is to know what to fix in the new box in order to get it connected to the router (through ethernet) and bridging the internet through.
My problem is that whenever I plug in the eth0 from the gateway (192.168.2.2) to the router (192.168.2.1), Ubuntu's automatic plug-me-in network detection kicks in and I find my dialup no longer working through some kind of IP conflict (at least that's what I think it is). Maybe I don't have the "gateway" correctly assigned? (in the gateway computer for the ethernet connection, I had it pointing to itself as I don't know what to put for "gateway IP" as that is automatic So, just to check my connection, here I am pinging google (from the gateway computer which has the dialup modem) once a dialup connection has been made.
Code:
lancer@lancer-desktop:~$ ping www.google.com

What do I need to do in order to make Ubuntu of my gateway computer stay connected to my dialup but also simultaneously share an ethernet LAN to my wireless router and feed traffic to the other computers from there? I have googled this but some of the most promising instruction (e.g. http://www.ubuntugeek.com/sharing-in...in-ubuntu.html) call for packages like dnsmasq or ipmasq which seem defunct now in Ubuntu 10.10. Other pages seem to suggest dual-networks "can't be done" in Ubuntu [URL].. (what!?! I had it before my other gateway died)
I created three pop accounts in evolution. For jka-walgau.at my name, office and mobile. The first time everything ran ok (all new mails could be downloaded, and from each account mails could be send). After a day (iIset the computer up for a friend) there arent no new mails that come in (webinterface tells me there are new ones).
SSL for pop and TLS for smtp were set.
The problem is they are selfsigned certificates. The first time when I configured the accounts and clicked the button to test the authentication methods I got a warning (self signed) no button to add this cert permanently only a OK buttton and in the upper corner the (x) to close. How should I handle this problem.
It could run on my computer. But there is no result.

I have a problem with the last point of some homework I have for an OS class. I need the program to print the pid upon execution, then for 10 seconds react to SIGUSR1, SIGUSR2 and SIGTERM. If either USR1 or USR2 is received, the 10 seconds are reset. Some of the functions I'm told to use are alarm(), pause() and signal(). The nicest way I found was to handle SIGUSR1, SIGUSR2 and SIGALRM in the parent process, with SIGALRM killing the child (with a SIGTERM). In the child a pause() (or for(; pause() would be enough for it to be alive until killed from the SIGALRM handler in the parent.
What I found is that I can't just do a wait() in the parent process, waiting for the child to be killed, since whenever the parent receives a SIGUSR1 or SIGUSR2, the right handler is called but the child exits nicely. I tried blocking/ignoring those signals in the child, since the default behaviour for SIGUSR1 and SIGUSR2 is to terminate the process, but the result is the same. The only way I could do it is using a waitpid() within a do { } while(!WIFSIGNALED(status)) since when the child gets killed with the parent's kill(), it's WIFSIGNALED, whereas when it exits after the parent handles a SIGUSR1/2, it's WIFEXITED.
P.S. What I'm doing to achieve the expected 10s window is calling alarm(10) in the parent process and again within the SIGUSR1/2 handlers. In the SIGALRM handler I kill the child and within the child I simply do a for(; pause()
I'm trying to connect to a Cisco VPN at work from Ubuntu 10.10. On earlier versions, I was able to import the config and get it working. In 10.10, though, the best I've gotten is being able to connect to the VPN, see the welcome message, and have packets sent over the tunnel. I don't receive any packets, though.
The command-line vpnc client connects just fine. I found this bug report: [URL]
The symptoms it describes are exactly what I'm seeing. The apparent solution is to "make sure in your config that LZO Compression is enabled (checked) under Advanced"; however I see neither an option for compression nor an "Advanced" tab, button, or anything on my VPN config in Network Manager.

I've been all over the internet trying to locate Linux drivers but no success. Alcatel's website says is not supported, only in Windows. I'm sure there's gotta be a way to use the X200 in Linux.
I have a doubt about signals in C programming. I have done this little program to explain it. It creates a child process with fork and, when the child ends, receives the SIGCHLD signal and wait for its termination.Ok, quite easy, BUT when I execute this code the SIGCHLD signal is received twice, first as an error (returns -1) and the second one to finish the child process.I don't understand the meaning of the first received signal. Why is it generated? Is the code wrong? (if you add the SIGINT and press Ctrl+C during the execution it also receives two signals instead of one)
Code: #include <stdio.h>
#include <unistd.h>
#include <string.h>

I have a Centos 5.4 server running kernel 2.6.18-164.11.1.el5PAE. It has an internal modem, and I need to be able to issue AT commands from a script to the modem. I need to simply dial a number and hang up. The relevant piece of my script is:
[Code]...
With an external modem, this works no problem. With an INTERNAL modem, the call never goes out. I fired up minicom to make sure the modem was working correctly, and if I issue those AT commands from within minicom, everything works great.
While minicom was running, I noticed a peculiar fact: WHILE minicom is running, the script works from the command line, and I can see all the AT commands and OK's in minicom, (minicom acts as a monitor). When I exit minicom, the script stops working. It appears minicom is creating a bridge between the com port and the modem itself. So, what is minicom doing that I'm unaware of?
The server's sole function is to run asterisk as a voicemail server (avaya wanted well into 6 figure territory to implement this....). This script is to dial an avaya FAC to turn the voicemail message lights on and off on the end users' phones.
I'm trying to set the gateway with my c++ program. My function receive the gateway on the first parameter.

I use Ubuntu 10.10 x64 at home. My company uses Microsoft RDS (remote desktop services, aka terminal services) at work and I'd like to know if it's possible to connect from home.
On a Windows machine, there is an extra tab in the remote desktop client that allows you to specify a secure gateway to connect through - this means you don't need to establish a VPN connection beforehand, it simply just connects straight away via an SSL tunnel.
I've looked at quite a few Ubuntu RDP clients and none of them seem to have this option.
Does anyone know if it can be done? Either that or I'd like to get my hands on a copy of the 64 bit linux Cisco VPN client that works. I've found a few copies around the internet but they always fail to install.

Of course I can do it manual (adding an default gw), but facing different wired/wireless networks its very unhandy.
Under Networkmanager -> Manage Connection You can edit a connection. If you do that, under tab 'IP-address' -> Configure: Automatic (DHCP) . Below you can select option 'routes'. In this field nothing is selected (I think that is correct). It must be something simple/stupid but what?
