Fedora Networking :: Configuring Dial In Over Usb - Serial Converter ?
Jun 23, 2011
I'm trying to do something very old, but for me very necessary. I am trying to get dial in acces via a modem that is connected via a usb <-> serial converter. I am running F14. The serial port is OK. I can run minicom and access the modem and even interogate it. What I am unable to do is to get the computer to answer. Much has changed and I have not dealt with upstart and things like that (if indeed that is needed).
I believe I"m OK with 115200 communicating with the modem. I know the device is /dev/ttyUSB0.
Is ther someone who can fill in the blanks? Or, point me towards really good documentation that explains how to do this.
I am trying to connect to a cisco console port using the usb to serial converter. I am using minicom and I changed me setting to reflect the USB converter cable, but it isn't working. I have set my baud rate to 9600, 8 data bits and no parity. Minicom acts as if it is connected (it doesn't give any errors), but there is nothing on the screen and nothing happens when I type. Also, I use the tail command and it sees the usb connector connected when I unplug it and plug it back in.
I have some USB-Serial converters and when I connect any of them for the first time a /dev/ttyUSB0 node is created. If I disconnect the device and then reconnect it then a /dev/ttyUSB1 node is created y I do the same again (reconnect) a /dev/ttyUSB2 node is created...
This is annoying because if mostly use only one converter at a time and because of the device node changing I have to reconfigure my software.
To reset the numbering of the device node I can force the reload of the usbserial module but before (I don't know when before) this was not necessary.
I have also checked if the device is being in use before disconnecting it (with lsof) and the device is not being used.
I am using openSUSE 11.3 , 32bit.I do the appropriate setting in 'minicom' application.I have two devices 'a' giving message at debug port at 9600 baud while 'b' at 115200 baud..Both 'a' & 'b' work fine when connected to serial port of computer.'a' works well if I connect it to serial to USB adapter which is plugged into USB port of computer.In case of 'b' , the above method yields failure.Do I have to set anything for device /dev/ttyUSB0 ?
My brother installed Fedora 8 on my 2004 Dell Inspiron 1000 laptop with a 56k MDC modem. I cannot figure out how to get the dial modem to work! Modem Device?, Baud Rate?, Flow Control?, Modem Volume?
I have a creative modem blaster V.92 which I know works because I have used it on windows and ubuntu how ever I am having some problems with F11 it sounds like its dialing okay and the box pops up that says please wait when I try to connect via the network manager thing but thats all it does the box never goes away and I've looked at the modem lights thing I added to my panel and it says its not sending or receiving anything and firefox doesnt work so I am not sure what I am doing wrong here.
I got an error with the default settings so I switched the device to ttys0 and set the baudrate according to what wvdialconf said was okay which also wont connect for some reason it hangs too.. I am confused here. Has anyone successfully set up a dial up connection in fedora 11
Trying to set up a modem connection under FC11, using the applet under System/Administration/Network/Add gives the following error:
Code:
Local variables in innermost frame: If the script is faulty, could you guide me through setting it up by hand? I am required to be away from my normal location for a few weeks starting Monday and need to keep in touch.
i have to work at my home in my office. For that purpose i use a laptop with Windows (i really don't know why) XP. As i moved to Fedora 10 i want to make the same thing in Fedora.. Really don't know how. i have a cable connection and a router at my home ( i posted another message mentioning the fact of my wireless connection).
At my office i have a router , a firewall and 2 servers that i am allowed to use and i have to work on them (one is an AS/400 from IBM).
I've tried both the firewall interface that comes with Fedora and Firestarter, neither can configure as I want. So I think I'm going to have to do it by hand. In this laptop I have one 10/100 Nic and one wifi connection, at times either of them can be connected to the network. How can I configure IPtables so that any traffic is allowed out, nothing is allowed in (other than std stateful firewall replies), no icmp and that the fw logs any attempts to connect to the laptop?
I have an internet connection through socks4 proxy form a server nearby to my laptop(fedora 12) i need to update and install sofwares. How to configure yum to use the socks proxy?
May I please have some help configuring wireless connectivity?I just moved and went from connecting to a LAN infrastructure to connecting with a wireless cable modem. The modem is dual-purpose, it has two ports, one for an Ethernet cable, and an access point for a wireless connection. The ISP is CableOne. My laptop, which I use most often, is wireless capable, and I want to use the wireless feature. The laptop is running Fedora 13 KDE, with a VirtualBox virtual drive running WinXP.
I have used NetworkManager to create a wireless connection and name it. I have also used WPA encryption for this because I don't want anybody else using my bandwidth. Moreover, I have tried no encryption and WEP, all to no avail.
Yesterday i've installed Fedora 14 x64 on my desktop PC. Everything is working just fine, but then i came to the problem of sharing internet connection for other computers (strictly speaking, two laptop ones) that i use at home.
I know, there were many articles that cover that problem, but nevertheless i was unable to make the things work.
So, going to the point (i would point it out for clarify):
1) My desktop computer has two Ethernet interfaces (eth0 and eth1) and single WiFi one (wlan0), that is not used at the moment.
2) Desktop's eth0 is connected directly to the internet via cable; interface is configured to work in DHCP mode and it is working properly.
3) Desktop's eth1 is connected to the router (WRT54GL, as far as i can remember model) and it was used (under Windows XP) to provide shared internet connection; it is configured to have static IP of 192.168.0.1 with mask of 255.255.255.0 (default settings for XP I-net Connection Sharing) and i've configured it in such way in Fedora.
3) Router (connected to the eth1 in desktop) acts also as DHCP server, that assigns IP addresses for all (but already static-assigned desktop) connected computers (no mater, cable or WiFi). Newly connected computer receives IP of 192.168.0.x, where x lies within range 3..63 (1 and 2 are reserved for desktop and laptop itself, respectively), mask of 255.255.255.0 and gate / DNS of 192.168.0.1
4) Both laptops have enabled DHCP (one uses XP, while the other uses Fedora 14 32bit)
When i connect laptop, it receives IP / mask properly from router's DHCP, but i have no idea how to configure desktop to route I-net packets from eth1 to eth0. First thing i've made was to enable IP forwarding, by adding line.
Code:
Code:
For the moment i have two questions: 1) How to check whether internet packets are routed properly ? 2) How to enable (or "route") DNS ? Is there a need to configure DNS on desktop ? Or somewhat DNS packets can be "routed", since during eth0 autoconfiguration it already receives DNS addresses from i-net provider ?
In windows, when I use an HSPDA modem, internet traffic will be automatically directed through it. Everything will go back to normal once broadband connection is disconnected. In fedora 12 this is not the case, internet traffic will still go through the lan interface. Is there a way to mimic windows behavior in linux?
Does anyone havea good tutorial on Fedora's network scripts, how to edit them, in what order they are called, etc. What I want to do seems simple, but something in the bootup keeps changing it. Right now, I have an image of Fedora Core 7 created in a server with 2 Ethernet cards. I need to specify static IP addresses for each card. Thats simple, and I did that. Now, heres the tricky part, I need to be able to clone this image and place it onto other exact duplicates of the hardware, and have all of the settings stay the same.
What happens here, is that eth0 and eth1 are stored somewhere as devices, and upon boot on a different machine, the Fedora will mount new network cards(different MAC addresses) as eth1 and eth2. It then mvoes my ifcfg-eth0/1 to a backup, and creates two brand new network setting's files, which initialize to DHCP. This creates an issue, becuase these machines do not have monitors nor keyboards attached, nor is their a DHCP server, so its a pain when I swap the machine out, to have to go in with a keyboard/mouse/monitor and reconfigure the network settings before I can connect to it over the LAN.
So does anyone have any advice on how to do this? No matter what i tried, booting the image in a new PC caused Fedora to create two new devices and create brand new network settigns for them, both initialized to DHCP. Hell, I wouldn't care if it created brand new devices, if it would initialize them to static IP addresses that I am expecting.
I have bought a so-called web'n'walk stick, which identifies itself as a "Globetrotter HSDPA Model". I managed to get it identified as a serial device (initially, it is detected as a USB drive), but I fail to get it working.
I've been running 8.04 Hardy since its first release, and was hoping to deal with its loss of support by going to 8.10 but learned that it has already been dropped.
So I'm back to installing 10.04 - and up against the bizarre choice to drop dial-up networking! Fortunately, I have my 8.04 machine still live, and I've researched it extensively without success.
The best summary of what I've done follows this post I found online:
-----QUOTE-----
I read many threads about dialup, including those on this forum; made sure to get an external hw modem [USRobotics 5637 USB, advertised as controller-based and tested to work in Linux], to avoid the softmodem/winmodem problem.
Using the 10.04 LiveCD, I installed the four .deb packages that are in poolmainwwvdial and in poolmainwwvstreams.
Now I'm stuck because I get errors when I try command line stuff, errors like "cannot open /dev/modem" and "can't find /dev/modem in /etc/fstab or /etc/mtab"
I'm confused; I've read so many threads with so much different info that I can't sort it out. Maybe I'm following info that applied to earlier versions of Ubuntu. Every error I try to fix leads to more errors. Can someone suggest a constrained, step-by-step procedure to ensure I've mounted the modem, added myself to whatever groups, and whatever else I need to do?
I know there's no wizard to make it simple, but is there a checklist or something to help me sort this out? I have the ISP info, DNS primary+secondary server numbers, phone numbers, etc. Is there a UI/graphical path, instead of command line? Had no idea this would be so difficult.
Ive been looking, and even tho dial up stinks, its better than nothing for me out here in the woods. I downloaded gnome-ppp. This should work for a linux friendly serial modem (US Robotics 9637 USB external)which is on the way.
I'm having trouble getting online, and therefore getting software, codecs etc, (I'm using another computer for this post) because the only option I have to connect to the web is through 56k dial-up modem, and this is apparently akward with ubuntu. I'm currently trying to work out how to get Ubuntu to recognize my modem. I have over-written Vista, which was previously on my laptop, although I did make recovery discs (though I really don't want to have to use them).
This is making it difficult for me to even find the model of my modem (it would involve reinstalling Vista and checking for the device under device manager, or Vista equivalent).I was advised to download the "Official Ubuntu documentation", and that this had a 'how to' section regarding dial-up modems. I downloaded it and searched it and found nothing as such. I also have downloaded the Ubuntu pocket guide and found nothing on the topic in it either.I can get online (via dial-up) on my XP machine, and also have USB storage sticks.
I'm using an external Huawei CDMA fixed wireless terminal (phone + dial-up modem). It connects to my PC via a USB port. Actually my PC recognizes it (after driver installation) as "TIUMP Serial Port". I guess the driver is a kind of USB adapter for a serial port.
I can't get it to work in ubuntu 9.10. I ran wvdial (after installing dependencies and wvdial package) and it doesn't recognize my device as a modem. Is there any solution to this problem? Without solving it, I won't be able to go online from ubuntu.
I've installed it and all went fine, now i want to set up a dial up connection witch i dont know how. I've tried going to system/adminstritive/networking but 'networking' isnt there.then i tyr gnome ppp but it says it cant detect a modem.
I have an internet connection with dial up created with pppconfig that I use Code: #pon connection_name to connect to internet in my ubuntu 10.10 platform and it creates me a connection over ppp0. I want to use a PPTP vpn, so I used this command
I use ubuntu 9.10 and PCI connected Conexant CX11252 Modem. My GNOME PPP doesn't detects my modem. How can I create a connection? Is there any way to detect my modem and connect ? or ubuntu is fit only for broadband? I think most of the activities in ubuntu depends on internet. I can't do any work. I am losing my money in Internet Cafe. Broadband is even not available in my resident area. Therefore. find a solution to connect internet via my dial up modem!
I have been working for the last week trying to connect my serial hardware external modem (courier 56K v.everything) within an Ubuntu 10.4 environment. I live in the boonies where I am presently forced to use dial up, so this has got to work, else I cannot update Ubuntu or download software. After trying various suggestions, which my very limited Linux skills fail me, I opted for the suggestion that I download gnome-ppp, install and then use it. Seeing how I cannot download it through Synaptic Package Manager (which I was advised to but can't as it is my Linux computer that I am trying to connect).
I downloaded the zipped file (gnome-ppp_0.3.23_Oubuntu2.tar.gz ) to a USB stick, copied it to the home directory and then extracted it, wherein a new directory was created with many files in it. From here I have been unable to install it through the command line (not sure how), nor have I been able, as was suggested, to install it via the Synaptic Package Manager (can't get it to see the file, not sure how to). I need explicit (Newbie) instructions on how either to connect the modem without gnome-ppp, or instructions on how to get gnome-ppp installed.
I have tried to install Gnome 3 in ubuntu 11.04 and rebooted without installing the gnome-shell. In consequence I see some error messages followed by blank screen after I enter my password in Gnome session, it says failed to load any session. So I have decided to install it by booting to recovery mood to the terminal console by connecting to my existing (working) DSL connection already set up in the Network Manager. Therefore, I need the command how to dial the existing DSL connection via terminal.
I have just installed an Edimax EW-7612PIn PCI-E Wifi card which has an RTL8192SE chipset. This chipset is not supported under current F15 kernels so I have installed the driver and firmware from source and have that working fine. The driver can see the card and I can issue 'iwconfig' commands successfully enough to see my Wifi network.
The problem I have is that I don't understand the relationship between iwconfig and wpa_supplicatant and as I'm running a headless F15 server I cannot use the NetworkManager GUI to help me. I should also note that the Wifi network is using WPA2-Personal encryption.
This is what I have done:
Configured /etc/sysconfig/network-scripts/ifcfg-wlan0 with what I think are reasonable values (based on google searches), including the ESSID, TYPE as Wireless, etc.
Configured /etc/wpa_supplicant/wpa_supplicant.conf, including using the key value returned from wpa_passphrase.
Arranged for wpa_supplicant to run from boot, using chkconfig.
However when I run 'ifconfig wlan0 up' I get the error message 'link is not ready' and indeed looking at the output from 'iwconfig wlan0' there are no configured values. I also understand that some values are configured by iwconfig and others by wpa_supplicant, however it's not clear what.
I am trying to configure my IPv6 network. My computers are behind a Fedora gateway IPv6-configured, which is working great. But for computers inside my network, it seems I am getting only internal addresses from DHCP. Here is my ifconfig for an internal computer:
I just can't seem to get this thing going. I've also tried Gnome-ppp. Press detect and it says "no modem installed" I did install it in Windows as well to make sure the darn thing actually works. It did perfectly.
Your US Robotics modem attached at /dev/ttyACM0 >>> The problemt: wvdial for some reason cannot use it
I had to edit the /etc/wvdial.conf file with gksudo gedit /etc/wvdial.conf
