Apr 16, 2010I was trying to use Message Queues for sending message from aninserted kernel module to user space. The function sys_msgsnd failedgiving the obvious error -EFAULT.However, I was able to send the message from kernel to user space when I had made the same driver part of kernel (and not inserting it).How is that possible?I am using linux.2.6.19.x (arch=ppc)I now use Netlink socket to communicate from kernel to user, but the aboveproblem seemed strange to me.

View 5 Replies View RelatedUbuntu :: Allow A Specific User To Mount Or Remount A Specific Partition?
Jun 9, 2010my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)

Fedora Networking :: Raw Packet Creation - Sending Specific DHCP Offer?
Jan 25, 2011I am trying to design an application which violates the DHCP. Specifically the difficulty in writing this application is physically sending the raw packet. I need some documentation on either a library that supports this or where to look for support for raw packet creation. I am not trying to create a raw datagram, that doesn't meet my needs because a raw datagram is still at layer 3 I need to craft a raw layer 2 PDU.
Specifically I want to
Send a very specific DHCPDISCOVER
Receive a DHCPOFFER
and pull apart the offer while never sending a DHCPREQUEST.
Specifically I am pulling apart various options that are sent in the DHCPOFFER. I have a raw DHCPDISCOVER already crafted and the formatted struct sockaddr_ll where I fault is I can't send the damn thing. Getting the file descriptor after calling socket is okay but what now? How would I write to that file descriptor and have it transmit?
Code:
int connfd;
struct sockaddr_ll bcast;
bcast.sll_family = PF_PACKET;
...
connfd = socket(PF_PACKET,SOCK_RAW,0);
//now what
Ubuntu Installation :: Error While Sending Message: Did Not Receive A Reply
May 1, 2011Since upgrading to 11.04 yesterday, nauilus has been acting strangely. It takes about 30 seconds for a right click on the desktop to respond, whereas before it would've taken 1 or 2. Also, when trying to open a directory, say, the Home direcotry accessible from the launcher,it takes about a minute to open, which is odd,because all of my other applications (Chrome, Banshee etc) ares all running smoothly. And when the direcotry windowe does open, within 10 sconds it will turn grey and prompt me to force quit. When i try to open nautilus from a terminal, it comes back with the message

OpenSUSE Wireless :: HOSTAPD's - Why Client Repeatedly Sending The (1/4) Message And Then Timing Out?
Jan 6, 2010I am seeing log messages that I don't understand. If I run tail -f /var/log/messages, some times I will see this this sort of repeating pattern. I don't know if I have cut at the start of the sequence or not. Incidentally, this is a normaly well-behaved client/host.
[Code].....
Why is the client repeatedly sending the (1/4) message and then timing out?
Security :: Hosts.Allow Vs. SSH / Sending Message Connection Closed By Remote Host?
May 29, 2010I have set up SSH and redirected the ssh server to listen on another port other than 22 for a bit of added security.
Now in hosts.deny I have:
ALL : ALL
In hosts.allow I have:
SSH : ip_address_of_client
I can no longer connect. I get the message: ssh_exchange_identification: Connection closed by remote host.
When I change hosts.allow to read:
ALL : ip_address_of_client
I can successfully connect the server.
However, I only want to allow SSH access in hosts.allow. What is the correct syntax?
I have tried and failed with each one of these:
SSH : ip_address:port_number
SSH2 : ipaddress
sshfwd-portnumber : ip_address_of_client

Server :: Script To Grab A Specific Message From IMAP?
Feb 14, 2011Is there some way to grab a single message from an IMAP server with a shell script? I'd prefer to avoid "scraping" an IMAP protocol session and instead use something like wget ... with some clever options.
The second half of this question involves specification of the message that I want to retrieve. Learning a specific "message number" is messy. I will likely know the TO: and maybe the FROM: details. I might also know the SUBJECT: I'm eager for your suggestions here as well.

Ubuntu :: Detailed Logging Of A Specific User?
Nov 9, 2010we are in a place where we have to give an account (with sudo access...) to a user we don't completely trust (I am reminded of this comic). What we need to set up is some way of logging pretty much everything that this user does, especially what he does as root (via sudo or sudo -s). Now, I know that anything we do can easily be undone by another user with root access, but we feel that if he does disable logging we can use this as a really good excuse to revoke his access. So, does anyone know what logging stuff I'd have to set up to completely monitor one user (it is ok if we are monitoring everyone, but we'd prefer to watch one user if possible)?

View 7 Replies View RelatedFedora :: Cannot Login To KDE As Specific User
Jul 17, 2010I have a very peculiar issue - I can't log in to KDE as one particular user (andrew, which is my regular account) though all other users including root, mythtv & other family members can log in without any problem. When I try to login as andrew the X server appears to crash as the screen goes blank and I have to press Ctrl+Alt+BkSp to get back to the KDM login screen. The proximate cause seems to have been updating KDE to 4.4.5 using yum - I did this logged in as andrew in a terminal session using su - root, and the black screen problem arose next time I tried to log in.
I can log in OK as andrew using a different desktop manager e.g. Sugar. I am using radeonhd graphics driver; if I change to "vesa" in xorg.conf I can log in OK. If I change the home directory for andrew to that of another test user and change the file ownerships, I can log in OK. Therefore the problem must lie in a config file(s) somewhere in the andrew home directory tree, which is specific to KDE and also radeonhd. I have checked in all the obvious (and unobvious) places but can't find anything. There are no relevant SELinux errors or entries in syslog or Xorg.0.log. The .xsession-errors file from a failed login attempt is here [URL] it isn't significantly different from a normal one, and as the entries are not time-stamped I am not sure which ones arise during the login and which when I restart the X server. I am running F13 (kernel 2.6.33.6-147.fc13.x86_64) without any other significant issues.
CentOS 5 :: Specific Uid And Gid For Default User
Jul 9, 2009Because I keep a lot of data on a Netgear ReadyNAS which can be presented as a NFS server, I would like to have the default CentOS user have a uid and gid that match those for the user that owns the main NFS share. That way I can treat it as if it were a directory that I owned on the local machine. I'm probably going to install CentOS 5.3 over again to get a totally clean system. What is the neatest way to ensure that the default user has the desired uid and gid? Or is there a better way to work with the NAS? (Right now I'm running it with CIFS shares, but these are quirky and do not behave quite like a local file system, I'm hoping that NFS would be more consistent, but previously attempts to run NFS were hampered by different uid and gid values).
View 1 Replies View RelatedUbuntu Security :: Limit Login Attempts For Specific User?
Jan 15, 2011I'd like to limit login attempts for specific user. I've found information in manpages: [URL]but I'm not sure if this '@' is purposly there, so would be that correct?
Code:
aparaho - maxlogins 4
or
Code:
@aparaho - maxlogins 4
Maybe '@' is a group syntax? I'm confused.
What happens after 4 failed loggins? Is it enough to restart system to get another login attempts?
Are there any other values that it is reasonable to limit for safety reasons?

View 3 Replies View RelatedGeneral :: Disable Telnet And Ssh For A Specific User?
Nov 12, 2010I am looking for a way to deny telnet and ssh to one specific user. So far I've only tested with telnet and my attempts have been limited to various hosts.deny entries:
in.telnetd : user@server
in.telnetd : user@server.domain.com
in.telnetd : user@IP_address
in.telnetd : user@.domain.com
None of these work. The only thing I've found that does work is:in.telnetd : IP_addressBut this is only a semi-viable solution because we will soon have multiple logins for the one username from different servers and sub-nets. Ideally, I'd like to be able to deny telnet and ssh access to this username regardless of where the login originates. I suppose it would be possible to specify each server IP, but that'll be a bear to maintain

I'd like for the terminal to be logged in as a different user as some of my end users are going to be using this and don't require such privileges. I found that I can "su" to a different user and start a new VNC daemon on :2 and when I connect to that session, the terminal is logged in as that user. What I want to do is get that to run at boot-up.
