Ubuntu :: Set Modem Speed To Match ISP?
Mar 30, 2011
I live in the boonies and I have dial up. Whats worse is the ISP has a limiter on the server which cuts the speed down to 26.4 k. Every time I download and the speed gets over that, the modem pauses then starts again. It sucks. If I could just have a steady stream I would be better off.
I am using a Linuxant type hsfmodem hybrid. How can I slow the speed down on the modem so it doesn't jump over 26k so much ?
I tried adjusting the baud which shortens the duration of the pause, I think, but when I go lower it actually makes it longer.

I am unable to install a ZTE AC8710 CDMA Hi Speed Modem on Fedora 10.I have somehow found the Linux Drivers but am unable to compile them as I do not have the required Kernel Headers which I can't download in Linux because my Internet is not working.I have tried the entire process of trying to add the Device ID and setting up xvdial but I am unable to find the ttyUSB or USBtty or USBacm in /dev.

I have the following query:
Code:
$sql="SELECT table1.datetime, table1.user_id, table2.ip, FROM table1,table2 WHERE id='$id' AND (table1.id = table2.id AND table1.datetime = table2.datetime)";
In table2 the datetime fields are about 1 to 2 seconds off due to the source of the data, which I cannot change.
Is it possible via a query match table1.datetime & table2.datetime by HH:MM (ie. to the minute instead of to the second)?

Ubuntu 64bit. The sound system works and plays noises correctly when I test the speakers in sound preferances. The internet BBCi player(Radio) plays sound correctly. Banshee & Rhythmbox try to play music files at double, or more, speed with no sound output. Spotify Linux version also tries to playback at double speed with no sound output. Media Player attempts to play music files at high speed. Media player plays the Video and audio tracks at high speed. VLC Will play the video at normal speed but with no audio.

find and install modem driver for the Alcatel X200 USB modem?
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 this USB modem P300U(SIM600 chip based) which works fine under wind@ws because it has it's own driver, but the clever seller told me that it worked under Linux as well. It was with Redhat 8 but I couldn't get redhat 8 to download. And until now absolutely false.
I have Debian with Kernel 2.6.32-5-686 I just want to send sms through this modem. It's not recognized as modem I'm frustrated because it's not useful for me if it doesn't work on Linux I looked for info but I can't make it work. What I get in my debian is:
lsusb: Bus 002 Device 003: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x Composite Device
dmesg: 9857.011649] usb 2-1: new full speed USB device using uhci_hcd and address 3

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've just installed Slackware 13.1 in two different laptops for first time. I have some strange internet browsing behaviour in one of the laptops. I've installed 2 internet browsers(firefox,opera) using the directions from Slackbuilds.org and there is also konqueror pre-installed. Moreover I installed Wicd network manager.
I can browse some pages e.g. ..... with firefox very slowly but NEVER facebook. I can browse almost any page, even facebook, with OPERA but very very slowly. The same goes with konqueror... Wicd shows that i am always connected with my WPA wireless network

My HD contains a Windows, Fat32, two Linux & swap partitions. Recently, I had to recover my partition table with "testdisk", due to a foolish attempt to resize a partition.I recovered all partitions, with the exception of my root partition. I left that unallocated, then reformatted it with GParted, to be of a larger size.All data has been recovered & the PC works fine, just as it always has.The wierd thing is that the original "root" partition seems to co-exist on the same partition as my Fat32 data(???)GParted shows my root partition as almost full, when it should only be about half full....then my Fat32 partition shows empty, when it should be about 3GB full. Root should only be about 5GB, not almost 9GB.I believe that my mtab & fstab are corrupt relative to the partitions that GParted lists, and need to be fixed. However, I don't know where to start.?

I just upgraded my laptop to Xubuntu 10.4. I have a nfs server I connected to with my old Xubuntu 9.10 set up. I loaded portmap and nfs-common then made a mount point. I chowned and chmodded the mount point in the terminal to my user name. But Thunar (the file manager for Xubuntu) won't let me open subdirectories. So I went back to the terminal and chowned and chmodded again with a -R. In the terminal I can read and write as user. Thunar (as user) says I don't have permissions to see the subfolders. When I start Thunar as root it assigns the permissions to my user name but not when I start Thunar as user. When I start it as user and browse to the folder and select properties it says the owner is root. What the frak? How do I get Thunar to see the permissions I set in terminal as sudo? Or better yet, how can I set the permissions for my mount point so that I can access and write to directories and files on my nfs share. I have no problems with my other computers with this server's shares.

How do I discover which kernel config parameters are important for my laptop hardware and frequently used applications? I'm not looking for something that is 100(...)% optimized for my hardware. I would prefer to have modules for everything that I don't use at all or often. I would prefer to avoid modules (built-in) for things that I use all the time but then any updates might mean a kernel rebuild. I'm currently running the generic PAE edition of the repository kernel. I think that I'm running the 32-bit flavor at that.
Code: user@host:path$ uname -a Linux mumbles 2.6.31-19-generic-pae #56-Ubuntu SMP Thu Jan 28 02:29:51 UTC 2010 i686 GNU/Linux I know the following from sysinfo

Say I had a string like so
Let's say I only wanted to grab TAC and BDX the ones in the 2nd, 4th, and 6th spot.
Will grab the lines from the rest of the file assuming these are the only lines with capital letters at the very beginning of each line.
Will delete the first 'T'. What I want to do is learn how to just pick the even characters, T(T)A(A)C(C) & B(B)D(D)X(X).
Is there something like the {1} which can pick just the even or odd character matches?

I need to edit the sudo file on lots of machines. I figure the easiest way is to run a for loop to ssh to each box, sed the sudoers file to a new file & copy/move back over the top of the original (and of course, change permissions accordingly)
The problem is, I'm not sure how to add a line after a match with sed.
So if my file looks like:
Code:
I'd like it to add the new sudoer after "other" so the file looks like:

I have Ubuntu 9.10 running on Dell Dimension 8400, 1 gig ram, Pentium 4. No other OS installed. Last night I decided to upgrade from 9.10 to 10.0.4 through Upgrade Manager with the upgrade button. The upgrade ran over an hour and errored in the "Installing the upgrades" step with the following messages on the Terminal screen:
"rpmdb: Program version 4.8 doesn't match environment version 4.7.
error: db4 error (-30971) from dbenv->open: DB_VERSION_MISMATCH: Database environmnet version mismatch
error: cannot open Packages index using db3 - (-30971)
RPM failed to open database, cleaning it up..."
I went to bed without doing anything. This morning at 7:30am EST I checked the status of this and nothing changed to the screen it was still stuck on this error with progress bar at 4 minutes in Upgrade Manager. I can move my mouse and even open Firefox 3.6.3 to search for issues within Ubuntu environment so I am not frozen. I haven't tried anything else yet.

In trying to solve a friend's lack of foresight, i have currently disabled my system.
I was using dd_rescue to make a copy of a drive with a corrupt and unfixable Partition Table. I was a fool, and had a drive mounted to /media/Storage, but ran the backup to /media/storage.
Thus, dd_rescue completely filled my primary drive before informing me that there was a problem.
I don't really trust myself with command line work, so I foolishly sudo'ed nautilus and deleted the folder /media/storage.
Unfortunately, I didn't realize it, but the available space on the drive still read 0bytes.
I tried Terminal work to do a sudo apt-get clean command, but for some inane reason, the laptop screen won't support the display setting for the Terminal login, so I just had to hope that I was doing it right.
I wasn't, and decided to try working from a Live CD so I could see what I was doing.
the folder /root/.Trash/ doesn't exist on Ubuntu's install drive, and I can't figure out why the properties of the drive say "contents: 241310 files, 3.7 GB" but also "Total capacity: 52.8 GB. Free space: 0 bytes"
Any suggestions on how I can get this to shake out?
