[Ubuntu 10.04]Every 60 seconds, 24 hours a day, a line like the following is logged to /var/log/messages and some of the other system logs:Code:Apr 27 11:37:48 HOSTNAME kernel: [DDDDDD.DDDDDD] ================>r8192_wx_set_scan(): hwradio offThat's with the wireless card disabled (since I'm using a wired network). If the wireless card is enabled, the message changes to "hwradio on".
View 1 RepliesI am building a live USB key using Ubuntu 9.10 Karmic. No upgrades have been applied. It is as it came in the ISO that was distributed.I would like to create a smooth start-up/logout process where no messages pop up (even briefly) that might confuse someone who is not very tech savvy. I'm referring to the messages that show up right before the login screen during start-up (between usplash and xsplash I think) that say:
"Starting early crypto disks ..."
and also the messages that show up on a black screen right after you initiate logout. It seems to sometimes show system messages including some error messages that can confuse users.Does anyone know of a way to hide, redirect, or disable these messages? I just don't want cryptic messages popping up even briefly that are going to confuse casual users. I'm stuck with version 9.10 since I've made some custom mods and would rather not redo them for a new release.
I want to know if there is a way to disable the GUI console on 10.04 Server I want the traditional pure text console ... no plymouth, no plymouth-theme, just 80x24 console. Another question, Is there a way to get those traditional messages when booting? Like 8.04 Server does?

I get every 10 min many broadcast messages (maybe by other user). How can I disable those broadcast messages, in order to not see them on my screen?
View 2 Replies View RelatedI have been running Senmail on SuSE 11.1 for the last few years with no problems.Since installing SuSE 11.3 a few months ago I have been having problems getting Sendmail to send to some (only a few) servers.If I disable the firewall # SuSEFirewall2 stop.I can send successfully using # sendmail -v -q, or # sendmail -v -qIxxxxx.When I re-enable the firewall I will start to get the timeouts/temporarily unavailable messages again (but as mentioned above, only for some servers) even though I can successfully telnet these servers when the firewall is on. When I disable the firewall the delayed messages can again be sent.Has anybody any ideas what I need to change (presumably in the Firewall) to get things working correctly? 'SMTP with sendmail' is already selected under 'Services to Allow' under YaST Firewall->Allowed Services..

For about 3-4 weeks, my file system used space was growing and growing. After some days, I decided to analyze the file system in order to understand what is going on. Well, the results returned that the log files at /var/log ( especially kern.log, syslog and messages ) were the log files that were sucking the free space. I searched if this was some kind of bug but it turned out that if these files are growing, the problem is in the records.
So I picked from the tail of the messages log the last 50 lines and I saw this:

Need some clarifications on TCP_keepalive . We are facing some issues on our Prod servers related to TCP functionality .The issue is like this for us. We have some machines at one end sending data in real time to another group of machines on the other end. Now due to some hardware issues on the other end , some of the machines becomes unresponsive/crashes. The client system which pumps data never came to know that the server went unresponsive . The connection remains in ESTABLISHED state and the client always tries to send data thinking that the connection is alive because of which we are seeing backlog on client sides.
Our understanding is like this on how TCP will handle the situation.
Q 1) Since the server went down , the client will try to the retransmit the data until it times out. What is the behavior of TCP after the timeout? Need clarification on the following things. a) Will the kernel will close the established connection after the timeout . Looks like no in our case as we

I have a C program which does.
1. Creates a UDP socket
2. Send the UDP Request packet to the TFTP server.
3. If the TFTP server is not listening in the 69 port, the remote machine send an ICMP ("Port Unreachable") message.
Is there a way to receive a notification from the Linux kernel on receipt of an ICMP packet to the created UDP socket.
I have a RHEL 4 server delivering long messages to several RHEL 4 clients. They work fine.I am trying a RHEL 5 client running the same client application as the RHEL 4 clients. The RHEL 5 client looses most messages. have tried with two other clients running CentOS 5 with similar results. The server indicates write failure or blocked. The messages are typically 50 kilobytes. I have changed many parameters in sysctl.conf Has anyone encountered similar problems?

View 4 Replies View RelatedI've just configured my Linksys RVS-4000 router to syslog messages to remote syslogd server (i.e. my CentOS5 machine). Redirecting messages was easy, but now I'm having difficulties to redirect those same messages received from Linksys to a separate log file. By default, all these messages are logged to /var/log/messages, and after browsing manual pages for syslog, syslog.conf, and syslogd, came to suspect that what I want isn't possible.

I suffer enormously from net addiction (as well as gaming addiction and related behavioural maladies).I've had revelatory success in controlling my time online-and, in general, in front of a screen with unproductive applications- by locking my monitor's power cord into an Ems PowerCop (the key to which I keep at work). Writing and journaling, I do on an AlphaSmart Neo. However, I could really use a tool to allow me to edit and typeset my writing (and only those tasks).I'm considering buying an ultra-low cost net-book.I want a netbook because it's the cheapest way to keep the display power fully dependent and integrated with the machine---I can't have something that will allow a simple means of working around the Ems PowerCop. Also, since it lacks an optical disk drive (and since I'll be keeping my usb drives at work) there will not be an easy way to reinstall the operating system. However, before I buy anything, I need to know that, after installing/configuring all of my preferred settings for vim and La/Xetex, there is a way that I can cripple the netbook and all of its applications so that no internet access is possible.
The Cherrypal Africa can come with either Ubuntu, Debian, or its own Linux blend, Green Maraschino. If it ends up being either Ubuntu or Debian, what can I do that will irreversibly (at least, from a software level---a hardware level would probably require damaging the usb ports, which I don't want to do) disable its ability to try to communicate with the internet (including the software repositories)? I'm hoping for a particular system file that I can delete rather than the addition of a command somewhere that would be easy for me to undo when I'm bored out of my mind and want to see what Wikipedia has to say about the glycemic index.
My wireless can connect to my router without a problem, but in order to do so (after boot) I must first disable networking in the Notification Area and then re-enable it. I don't mind it too much, but when other people use my computer, it's made painfully obvious to me, that this was never an issue with Windows 7 (as much as I despise MS).
