General :: Home Broadband (TWC/RoadRunner/San Diego) Intermittently Drops Out For Minutes At A Time?
Nov 19, 2010
Our home broadband (TWC/RoadRunner/San Diego) intermittently drops out for minutes at a time. In WinXP, I had a logger that would ping one or more sites (e.g. Yahoo.com), log the ping times, and display the data in an interactive graph. This was very useful in showing the ISP tech (I didn't know about Shibboleet then).The problem is still unsolved after two visits, but now I'm using Ubuntu 10.04. I'm looking for a similar tool. I'm a Linux newb (i.e. "just write a script" isn't helpful at this point), so I'm hoping for something user-friendly with a GUI.Can anyone recommend a Linux utility that...Logs ping timesDisplays results graphicallyDoesn't require advanced Linux skills to set up

Recently, Putty keeps intermittently freezing and locking me out of the system (i.e. I can't stop the session and I can't re-login via ssh again until I've gone to the machine and pressed "reset").
So far, it mostly occurs when opening a file in VIM, but it does sometimes occur when using tab to auto-fill a file or directory name at the command prompt.

i have an asus eeepc that i recently upgraded from ubuntu 9.10 to 10.04. the wireless networking has worked great up until about 2 weeks ago. now it occasionally drops the connection (can't ping the gateway), even though the "blue bars" still say connected. my current solution is to click the bars, do a "disconnect", and then reconnect.i've ruled out the router being a problem (all 17 other wireless devices in my house remain connected), and i've ruled out a laptop hardware problem (when i dual boot into win7, i never lose my connection).
i'm new to linux (installed 9.10 back in february), but not new to computers/networking. i run a major campus lan [windows based] and have worked all aspects from the early mainframe days to client support to server admin to helpdesk - after 17 years, i'm now in management, so i've lost my edge a little... plus, being brand new to linux, i'm feeling a little lost in the troubleshooting aspect of this.i do believe that i've narrowed my problem down to "almost exactly" when this occurs. the wireless connection drops out as soon as i start to do "network intensive" stuff like watch a videos video, play a facebook flash game, or (and here's the kicker), try to run the update manager. unfortunately, this means that i have not been able to update for a few weeks now. i'm up to about 150mb worth of updates that are waiting.

Hello, I've installed OpenSwan with xl2tpd on my server, and set it up for roadwarriors connecting using certificates.
My server is Debian 5.0.8, I am running xl2tpd 1.2.0, and Openswan IPsec 2.4.12, my clients are all Windows, and I am testing my setup on a Windows 7 client.
I have no problem connecting to the server, but after some time the connection drops. I removed the idle option from the ppp config but it does not make any difference.
Even when I create constant traffic with ping -t the connection drops also.
I have no problems reconnecting right away.
I have been hacking at this for a couple of days, reading every post I can find, but I have not found a solution to my problem.
Here are my configs and logs:
CONFIG FILES:
/etc/ppp/option.l2tpd
-----------------------------
ms-dns 10.248.75.4
ms-wins 10.248.75.4
asyncmap 0

Having struggled to get the wireless connection at least working I find it drops out after 15 minutes or so. When I check for wireless connections I can see none at all and the "Disable/Enable wireless conncection" has disappeared, the Network one is still there. I get an auto reconnection if I reboot and all is well for another 15 minutes. Is there any way i can recover the situation without a reboot? I am trying to install the hplip-3.11.5 driver for my new wireless printer,the program take a while to install and by the time it has started looking for the printer the connection has dropped out. I can't be sure but I don't think it was dropping out before I connected the printer using my wired pc. All good fun but I'd like to get it sorted so I can get the engine back in my motorbike, the sort of technology I prefer!

I'm having problems with my mobile connection. This has been working fine for months, but in the past few days it has connected OK, I've been able to transfer data, but after 30s the connection closes. Setup is Acer AA1 with F12 connecting via bluetooth to Nokia 3110c on O2.
So to try and figure out what's happening I put the bluetooth dongle in my desktop PC, also running F12, made a connection and again it dropped out after 30s. Then I fired up windows on the AA1 and made a connection using the same dongle, this time it held up OK. This leads me to think that something has changed recently in F12 to upset it.

I have a Dell 1545 laptop with ubuntu 9.1 32-bit installed (the 64-bit had a bug with the wireless drivers which is why I have not used it). Initially, the laptop worked well with the wireless (a sky router with WPA security) but now, the wireless signal drops after a couple of minutes of usage. I have to reboot the laptop or sometimes reboot the router as well to regain the wireless signal. I am using the Broadcom STA proprietary wireless driver.
I have an older dell inspiron 6400 as well with the same OS and driver and it works perfectly without any problems for hours / days.

From the posts relevant to postfix I could not find the particular combination of issues I'm facing. Any pointers or references to posts will be greatly helpful. I have CentOS server running Postfix which was recently moved into my house running over TW cable (Austin RoadRunner). In Webmin -> Postfix Mail Server -> General Options - Other General Options - 'Send outgoing mail via host' (which is the relayhost) is set to:
Code:
[URL]
I expected the relay to reflect this in the log but it doesn't When I send an email I see this in /var/log/maillog
Code:
Jul 21 17:10:46 cromagnon sendmail[14853]: p6LMAjlu014853: from=root, size=49, class=0, nrcpts=1, msgid=<201107212210.p6LMAjlu014853@cromagnon.com>, relay=root@localhost
And a timeout occurs a little while later
Code:
Jul 21 17:17:04 cromagnon sendmail[14853]: p6LMAjlu014853: to=ravi@pobox.com, ctladdr=root (0/0), delay=00:06:19, xdelay=00:06:18, mailer=relay, pri=30049, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection timed out with [127.0.0.1] I basically *all* mail from all domains on this server to go through the relayhost. I understand there are a million caveats but I wish someone could help me with the basics.
BTW I've also tried to set the relayhost to
Code:
[URL]
however the log still shows . . .relay=root@localhost . .

I'm running Fedora 14 and set the screensaver (in System>Preferences on the Gnome GUI) to activate after the computer is idle for 30 minutes. After the screensaver is activated, and a press a key or the mouse, the screen is back to normal -- no problem.After the screensaver has been activated once, however, it comes back on very quickly -- usually in 2 or 3 minutes if the computer is idle. The only way I have found to correct this (and set activation back at 30 minutes again) is to log out and back in again.How can I correct this, and automatically set screensaver activation back at 30 minutes each time the normal screen is reactivated?

I did a fresh install of Slackware 13.37, and everything is great, and thanks to Pat and the team.
Recently I notice that Wireless drops out all the times, and it will show low connection first, then basically drops.
Is there anything I forgot to do?
For me, I normally have two ways to bring up wireless, sometime I use WICD, sometimes I just use "ifconfig....iwconfig...dhcpcd eth1"
btw, if I log in WindowsXP, wireless never or seldom drops.

I could not find an answer to this. I can connect to the internet no problem after I edit the connection name to NETGEAR instead of our last name. After a while it looks like it renews the connection and created a new one with the wrong name. The connection drops. It looks to me it is not using the same wireless connection each time but creating new ones that do not work for the above mentioned reason. What can I do to stop the loop and have it use the same connection always?

This server will run Centos 5.5 as Xen Dom-O+Raid 5/10, this will be the main point to attack.

I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69
real 9m54.886s
user 0m5.536s
sys 0m1.740s
$ ls -l test-32000.wav
-rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?

My Linux system shows a current time with the date command that is 12-14 minutes behind the time shown by my DirecTV satellite receiver or my wife's MS Vista system. ntpd is running; it's polling several ntp servers; ntpstat claims that the system time is accurate to 11ms.

I have a 9x320G RAID5 array that I am migrating over to a 3x1.5T RAID5 array.Intermittently, a drive would drop out of the older array and it would automatically start rebuilding. I thought it was a bad cable or controller somewhere, so when I bought the three new drives, I bought a new controller for them all, too. I'm running both arrays side by side until I'm happy the new hardware is stable (one drive was DOA). Then I noticed one morning that both arrays were rebuilding themselves. This was in /var/log/messages:
Quote: Jul 5 00:30:19 mnemosyne -- MARK --
Jul 5 00:50:19 mnemosyne -- MARK --

I have xscreensaver installed and configured. I have it set to turn on after 5 minutes, cycle every 5 minutes. I have acpi setup to blank my monitor after 10 minutes and power off after 15 minutes. The problem is, sometimes it works, sometimes it doesn't. I haven't figured it out. The service from what I can tell only runs when the screen saver is active. So checking ps -e doesn't tell me much, and since there isn't a true problem it is not recording anything in the logs.

I did a clean install of Ubuntu 11.04 64bit and the start up time is abnormally slow. If I start up the computer and don't press anything, the start up time is 30 minutes but it usually doesn't start up at all. It just boots into a purple screen, no splash, then it sits there and the computer doesn't have any loading lights flashing.
I had a similar problem with 10.10, but I assumed it would go away when I did a clean install of 11.04.
I can't get a read out of what's going wrong because when I press Esc it doesn't display anything, though weirdly it can sometimes get the start up process moving. I have also found that pressing enter really fast can sometimes help and something that seems completely oxymoronic, if I press the power button while it's starting up that can make it work, but nothing works every time.

I'm using Scientific Linux on a laptop, connecting to a debian server on my LAN via a basic BT HomeHub router. When starting a file transfer with ftp or rsync from the laptop my connection is dropped, every time, after a couple of seconds. I have to reset my network adaptor and restart my network manager (wicd in this case) in order to get network connectivity back. I had a very similar problem before - [URL]. On this occasion my workaround was to replace NetworkManager with yast. I am now using SL though so no yast available, and I am not using NetworkManager any more anyway.

I've restarted a server a couple times, and during the boot process pings respond when it brings up eth0, but then when i get to the command line login screen, the pings die. once i log in and do a ./network start the pings respond again, so i'm guessing its dying or not set to start automatically maybe? What should I check?

My MBP fails to boot Arch. This is what I did to install ArchLinux. Install rEFIT.
Partition using disk utility such that first one is Mac partition, second is Arch & the third ie the last one is windows.
Then put Windows 7 CD, select it from rEFIT and install it. Similar, install ArchLinux just as I did for windows.
Then finally to install the GRUB, I issued the command $grub-install --root-directory=/mnt/arch - recheck /dev/sda3 (after mounting my /dev/sda3 to /mnt/arch).
This is the exact error and then it drops to recovery:
Error after typing exit:
I have tried rootfstype too. No success.

I have a secondary disk which holds a /home directory structure from a previous install of Linux. I installed a new version on a new primary drive and mounted this secondary drive as the new /home. Problem is, even though the users are the same names and I can access the home directories for the users, I cannot login directly to their home directories, as I get the following error: -
Code:
login as: [me]
[me]@[machine]'s password:
Last login: Wed Jan 6 18:34:33 2010 from [machine]
Could not chdir to home directory /home/[me]: Permission denied
[[me]@[machine] /]$
Now, since the usernames are correct and the users are in the passwd file with the correct home directory paths, could it be user ID's that are different or something else? It's not as though I cannot access the home directories for the users, simply that I cannot log directly into them from a login prompt.

Is there anything special about a home directory before users' home directories are stored there, or is just as typical as any other "empty" folder?Let me just cut to the chase, but please no ear ringing about the folly of messing around as root, particularly with directories at root level. I know it's considered stupidity, but I deleted my home directory.
Is there an easy way to restore a working home directory? I tried copying /etc/skel under root, but I'm not sure what a home directory should look like once it has been restored. Besides . & .., there were .screenrc & .xsession in my home directory when I copied /etc/skel. Are these files suppose to be in "/home" or "/home/~" or both?
