I need to make a validation before start my application, so I read the Hard Drive serial from the /sys directory (sysfs).
So I was thinking if there is someway to star Linux without the /sys (sysfs) and put manually some files, and override the real hard disk serial.
I just installed Gentoo.
Everything's working fine except for this error I get during bootup: udev: missing sysfs features; please update the kernel or disable the kernel's CONFIG_SYSFS_DEPRECATED option. udev may fail to work correctly
I don't know what to do with this. I built the kernel using the genkernel script. I'm using kernel 2.6.31-gentoo-r6 on an amd64 processor
can anybody clarify my doubts what is the difference between swap , tmpfs and sysfs filesystem?? also what is the use of /dev/pts and /dev/shm and ?

in /var/log/boot. This box is running as KVM-host, so I am a bit worried about 'warings' like these...
This link, acpi: thermal/sysfs-api, explains how the new thermal management sysfs class is built, but doesn't give much information about using it. Using watch, I can see that the cur_state of cooling_device2 changes from 0 to 5 when I check "Dim display when idle" in Power Management Preferences. But I haven't found an applet that changes cooling_device0 or cooling_device1.
Echoing different integers to the cur_state files limits the maximum cpu frequency for cpu0 and cpu1, respectively. This behaviour is expected from what I've read, and mimics the options in Windows power manager for extending battery life by throttling the CPUs. I've had no luck with google and local man pages, so has anybody has seen an applet for controlling /sys/class/thermal/cooling_device[0|1]/cur_state?
On a side note, a value of 1 does slow the CPU down, but it will still hit 100C (normal for an Intel mobile duo core). However, values of 2 and larger throttle enough to lower the maximum CPU temp. Since the CPU temp is a good indicator of power consumption, it's pretty obvious that these two cur_state files are intended to extend battery life. dd_wizard
How can I figure out the "Device" name from the "Sysfs" node? e.g. [root@baba 0000:00:01.0]# lspci | grep -i Ethernet
00:19.0 Ethernet controller: Intel Corporation 82566DC Gigabit Network Connection (rev 02)

I installed Ubuntu 10.10 64-bit, downloaded Adobe reader '.bin', from the terminal

I'm trying to find how to schedule a process to start at a specific time (not on start up). How would I schedule a process/application to start at a specific time (if it matters, it will be a background process). For instance, have process abc start every weekday at 5am. I've done this for windows many times though have only been using linux regularly for a few months and haven't figured out the best way of doing this.
So far the best solution I have is to create a program that will start on boot and have it check the time and sleep until the required time and then start the required process(es) at the required time(s). But this seems more of a hack since I'd expect there to be a proper way of doing this.
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 have a mysql database and i use it with apache for my webpages. And I guess it dosen't start when the computer starts so I have to manually start it with "sudo /etc/init.d/mysql start" This returns fail so i went to '/var/run/mysqld/' and the folder was empty. I don't know if this is the problem or not. How can I fix this?

I just moved my / from sda1 to an ide drive, hde1. i dont see how this could have caused any of these issues, but it did.
First my network card failed to start. i added a line in my rc.local file (where i put all of my additional programs, etc i want to start):/etc/rc.d/rc.inet1
The above now starts my network card with my static ip configured. dhcpcd also worked but i wanted this static.
Now samba will not start. i have the following line in my rc.local: /etc/rc.d/init.d/samba start
This used to work just fine. at first i thought that samba may be trying to start before my network card gets an ip, but the line is *after* the network startup line. just to make sure, i made an additional script called startsamba which contained a sleep 60 followed by samba start, to delay the startup of samba even further.
The message samba reports is very vague, something like failed - core dumped. most of the core dump log is garbage characters, but here is the beginning which seems like it might contain some info:
Code:
ERROR: Can't log to stdout (-S) unless daemon is in foreground (-F) or interactive (-i) after the system starts, i can drop to a console and type "/etc/rc.d/init.d/samba start" and the service starts just fine. i've also tried starting samba manually with "smbd -d" which also produces the core dump when started from rc.local, but not when started from a console after startup.
I'm configuring a new Centos 5.5 server in replacement of an old W2K server.The topology of our network is simple : one file/dhcp/dns relay server and workstations (PC's and some MAC's) plus network printers and scanners.All the workstations have dynamic IP addresses (easier because a lot of 'dynamic' changes : new persons with their own laptop, ...) and the server and printers/scanners have fixed IP addresses.I edited the dhcpd.conf (see here underneath), I have the file dhcpd.leases but it doesn't start !

I've been fighting to get my wireless working and I've finally made some progress. I can actually manage to connect to my wireless network and so far it has been quite stable (fingers crossed).
However there is one slight nag. My wlan0 interface driver refuses to start at startup. When I type iwconfig its just not there. To fix this I have to manually run "rmmod rtl8187" and then "modprobe rtl8187". Then it works fine.
I've been trying to make a script to automate this but without success. I've tried both editing my rc.local and kde startup .xinitrc

View 2 Replies View RelatedI just installed KDE under Arch Linux. Problem is, nothing is starting up right with it - no window manager, no panels, nothing. All I get is a small terminal window in the bottom right corner of the screen, which I'm assuming is konsole. From that single window I can do things like start kwin or launch programs whose names I happen to know (like chromium or firefox), but I don't have a panel for starting programs or switching between programs. Even Alt+F2 doesn't bring up the normal dialog.
It doesn't matter whether I start kdm through inittab or manually by typing # /etc/rc.d/kdm start. KDM looks great, but once I log in as my normal user I just get a console window with no decoration.Is there a startup script for KDE somewhere that needs to run, and usually has a bunch of programs by default - like a window manager, panels, widgets, and all the normal background programs that run in an ordinary GUI? If so, can someone show me the default script so I can work from there with a window manager, decorator, launchers, etc.?
I've configured ssh on opensuse a few times without issue, and to get it to run at boot I've used 'chkconfig ssh on' and it's done, sshd starts at boot.
I've recently started to use Debian 9.04, and for the life of me I cannot get ssh to start at boot, or to be more exact, if I try and connect via ssh I get 'Network connection refused' and 'ps -ef|grep ssh' shows that it is not running.
1) If I start it via '/etc/init.d/ssh start' it runs fine until the server is rebooted
2) I've done 'update-rc.d -f ssh defaults 20' it returns that the links are already in place
3) During the boot up process I can see 'Starting openBSD Secure Shell' (it was also at this point I discovered that BOOTLOGD is not enabled by default)
Another strange thing, when I edit /etc/motd it is not retained after a reboot.
