I currently have something like
Code:
crw-rw---- 1 root dialout 188, 0 Nov 14 15:00 /dev/ttyUSB0
How can I get permanently
Code:
crw-rw---- 1 root uucp,dialout 188, 0 Nov 14 15:00 /dev/ttyUSB0
My home banking software needs uucp there...
I would like to set both user and group permissions permanently to be 'rwx' (read-write-execute). I would like these rwx settings for all the future files and folders.
I tried umask 002, chmod etc, but they don't set it for future files.
The uuname command available in solaris lists the names of systems known to uucp. Since uucp is also available in linux, is there any command which lists the names of systems known to uucp in linux? I 'm using fedora9 linux machine.

Recently i acquired an electroencephalograph (EEG) and started to experiment with it, and i need some way to write or send a couple of Hex numbers to the EEG so it will start working, and then to save the data on text file, or at the very least see the output on the terminal using C or C++, i found some programs around the forums but none seem to work properly and more often than not, The EEG is recognized as /dev/ttyUSB0 has a baud rate of 921600.

How can I program my PIC micro controller through the USB port using Piklab or Ktechlab IDE? I have already installed gputils,SDCC and Piklab!!
how to interface with the PIC boards ICSP through the USB port??( Db9 is not a choice for me as I have a Db15 pin in my laptop hence the need to work thru the USB)
I have been thinking of a USB to Serial along with a serial to ICSP converter but it turns out to be very slow!
I'm developing a serial port application under Lazarus using the SunaSer code library.
The application reports an error indicating that "the Port is opened by another process".

View 3 Replies View Relatedi have been able to get on line running other linux os using the terminal first i type sudo modprobe -r usbserial & enter followed by sudo modprobe usbserial vendor=0x1199 product=0x120 & enter the last command is sudo dmesg|grep -i ttyusb. I have done this for years and it always has got me on line after the above i open kppp and select for modem /dev/ttyusb0 and click to verify kppp recognizes my sierra wireless usb modem and that is all i have ever had to do, plug in the usb modem type the three commands it comes back with confirmation the modem is attached to ttyusb0, ttyusb1 & ttyusb2 in kppp i click /dev/ttyusb0 and click quarry and get on line with suse11.1 it is not so the first command sudo modprobe -r usbserial comes back with a fatal error but the second and third command give me the same results saying i have attached the usbmodem to ttyusb0,1 & 2. but i cannot configure it in kppp.
i have tried researching on line but cannot find a similar thread. I believe the way i described above has worked on lindows 5.0, and it is how i do it with Mint which i can get on line with today. so i hope one of the wonderful millions of linux users will direct me as to what i am doing wrong. i am running amd 785 4 gb ram msi mainboard ms-7549 my modem is sierra wierless modem 595u (vendor=0x1199 product=0x120) connecting through Sprint pcs which requires no user name or password.
I've been tasked with fixing a Red Hat system that dies with a kernel panic during the boot stage:
Code:
EXT3-fserror (dev sda1): ext3_check_descriptors: Inode bitmap for group 4 not in group (block 67239937)!
EXT3-fs: group descriptors corrupted!

I can boot into a Rescue CD, but I'm a bit out of my element because I don't use EXT3 myself, and I've never had to repair a corrupted file system before.
I have a group (GROUP) with a number of users. I recently added a new user (NEW). NEW is able to read but not write group files, whereas all the other users in the group can read and write to the group files. The permissions for the group files indicate that all members of group should have write permission -rwxrwxr-x
/etc/group indicates that NEW is a member of GROUP
...
GROUP:x:501:GROUP,OLD,OLD2,OLD3,OLD4,....,NEW
[code]....
Don't know if it matters, but both OLD and NEW write to the GROUP files over an internet connection. why NEW can't write to GROUP files? Is there a maximum number of members in a group that I might have exceeded?
Mount of filesystem failed. A maintenance shell will now be started CONTROL-D will terminate this shell and retry. groups: cannot find name for group ID 0 root@Sergioc-desktop:"#

A bit of an oddity that I've recently run into with my storage folder in my system; it's a newly installed drive that I've set to mount at /storage. When I first tried to use it, programs that I used that attempted to write to it tossed Access Denied errors at me in their own way. Checking the permissions (at the Terminal, ls -l / | grep storage) showed that /storage was set to 'rwxrwxr--'--Owner and Group were given full read/write/execute, but Others could only read. However, my logon to my system is a member of group root. Why, then, with the above bits set, would I not be able to write to it? Changing Others permissions to rwx (and presumably rw would have worked out for me since I don't leave anything executable there) allowed me to write to it, but I don't understand why that would have been necessary. So far as I'm aware, the prior drive that was in my system--mounted at the same location--did not need this treatment.

Cmnd_alias SU=/bin/su -l %group1 This example works sortof, it treats the "%group1" literally. I know I can list out the "/bin/su -l <eachuser>", but as you can imagine that is impractical. In this example, I want people in group2(not shown for brevity sake) to be able to su to someone in group1

So I just installed Ubuntu on my second laptop, however I ran into a problem. The F9 key is going crazy. I'm not exactly sure what is causing it (I've already popped off and cleaned the keys) but if I could find a way to just disable it I'd be very happy.
View 3 Replies View RelatedSo grub2 snuck into my upload list.
Is there a way to force APT to never, never, ever, never, ever, even in the slightest EVER consider even thinking about possibly touching the satanic filth that is grub2?
I'm growing weary of the same loop... grub gets flagged for upgrade to grub2, I don't notice it, system breaks, boot rescue disc, remove grub2, restore original grub, move on with life.
I thought by purging grub2 and setting grub to manual maintain (apt-get install grub after it is already installed) would be enough, but apparently not so. So is there a way to ban this package? Seriously I'd rather start using Windows again than use grub2. To this day I have never successfully booted anything with it and it just sends me into a rage when I see the crap grub_rescue pop up after it sneaks in an update.
For Oracle installation, I need to set kernel.shmmax parameter to 8416559104
According to the manual I did the following:

It looks OK, but after reboot there is the default value 3294967296 again.
The system is 64-bit SLES11.
I will be switching to Debian soon and have been forming a large script with a vbox test system to automate my system configuration when I switch.
When I install lamp (Or basically it's equivalent packages) apache and mysql start up automatically.
I could just use update-rc.d to remove the autostart but whenever there's a security or feature update for the package the files get replaced.
In addition, for some reason the system thinks it's a good idea to autostart half a dozen apache2 processes at the same time, sucking up a good 150Mb ram when not doing anything. (Anyone know why?)
How would I stop my system from doing this? Could I "chmod 000" the /etc/init.d files?
I came across the following method of how to permanently disabling selinux and it's notifications. Although changing enforcement from the gui into permissive mode does most of the job, the notifications still pop-up when some applications are started.
So to disable it do the following:
open terminal as root and execute:
Quote:
And then change the SELINUX line to SELINUX=disabled
Quote:
This is it. Now reboot the system and selinux will never bother you again.
If you are not a Fedora user and you are using this forum just because we are cooler here then you will not find the /etc/selinux/config as in the fedora releases. What you need to do is to edit the kernel boot line and add selinux=0 at the end:

I have various repos in my yum.repos.d including rawhide, google, and various others which I can enable on specific yum commands with --enablerepo=reponame.
Question is, how come these aren't enabled by default? When I do a yum repolist they don't show up, which effectively leaves orphan programs.
I can see why you might not want rawhide enabled by default for obvious update reasons, but I might want others to be enabled by default, like google for one.
So how is the default repo anabling/disabling controlled?
