Fedora Networking :: Permission Denied When Sending Packet Using DITG?
Mar 14, 2011
I'm implementing static IPv6 address on two Fedora 13 installed hosts. These two computers are connected using a switch between them and I use D-ITG to generate traffic in the network.I need to send packet from host1 to host2 using this command and I got permission denied
Code:
#./ITGSend -a 2001:db8:c003:111e::3 -T UDP -x recv_log_file -t 30000 -c 32
Connect error in createTransportChan(): Permission denied

I 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

I run a small home network with a wireless network using Apple airport wireless router. I have two macs and one Linux box (Fedora 13). Everything worked until about a week ago. Now the two macs can communicate with each other, and one of the macs can communicate with the Linux box, but the other can't, which is a bummer because it is a print server.
Pinging from the mac to the linux box gives the error message:
ping: sendto permission denied
Ping from the Linux box to the mac just hangs:
[/home/pjs] # ping 10.0.1.5
PING 10.0.1.5 (10.0.1.5) 56(84) bytes of data.
Firewalls on both boxes have been disabled. The Mac was running Little Snitch, but it has been uninstalled.
I have looked for messages from /var/log/message using tail -f and there are none when I ping either way.
ifconfig and /etc hosts, hosts.allow and hosts.deny look normal.

In order to debug a problem, I want to list down as many as possible reasons of a server (SOAP server running on Fedora 10) sneding RST in middle of packet transfer. Please note that in my case, SYN and ACK of initial handshake went through. Server received request from client and started data transfer but then suddenly, server sent RST in between data transfer.

we have a minor issue with time synchronization in proprietary equipment.the client needs to synchronize time with server, but not using NTP.it is not very important so doesn't need to be done often.the problem is that it won't synchronize. I can see the server is sending tcp packet with date&time, but the client ignores it.I suspect the problem is in format (manual specifies there are two possible options like MM: DD: YYYY and so on, but server seems to use some other)Is there an easy way to run some program in Linux Debian, to send that simple packet with correct date?

I have a mount problem with a NFS server on Debian Lenny. No matter what I do, I cannot mount a directory from another Debian box on the same network.
The error the client gives:
The server reports:
But there it is, in my exports:
cat /etc/exports:
Doing a:
NOTE: this default has changed since nfs-utils version 1.0.x
Comes up empty (and it should not, right?)
There is no firewall inbetween. No access restrictions via the tcpwrappers.

I'm sure there is a very trivial solution to my problem but I just can't figure it out due to my lack of knowledge.I want to mount an nfs share share on client1. The share is on server1.The server1 /etc/exportfs has entry: /backup client1 rw,all_squash,no_subtree_ check) The client1 sudo mount works just fine: sudo mount server1:/backup /backup..Can anyone let me know how to mount the nfs whare with options to read/write permissions for a regular user. And then put that mount into /etc/fstab? Should I mount first and then change the ownership of that folder?

I just set up a storage server with NFS sharing. Everything work fine but, when trying to mount the remote partition on my ws, this is the issue:
/usr/sbin/start-statd: line 8: /sbin/rpc.statd: Permission denied
/usr/sbin/start-statd: line 8: /sbin/rpc.statd: Success
mount.nfs: rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
I tried so to mount it locally :
mount.nfs: access denied by server while mounting localhost:/var/ftp/pub /mnt
I don't think it depends because of the permiss of the directory, and anyway it's 1777.

I have followed that many post about using a Windows mount, and still have an issue.
Using Ubuntu 8.04 to mount a shared on a Windows 2003 Server.
I have the fstab method with this line:
//server/xms /mnt/xms cifs defaults,uid=1000,gid=1000,credentials=/root/.smbcredentials 0 0
or
//server/xms /mnt/xms cifs credentials=/root/.smbcredentials,iocharset=utf8,file_mode=0777,dir_ mode=0777 0 0
Both work when doing a mount /mnt/xms command. I can ls the directory on the windows share. I can cat files from the windows share.
If I touch or mkdir in the windows share I get "Permission denied"

I wanted to use NFS4 with id mapping. I followed the write up at [URL] and basically have everything working.
The problem is that I cannot write a file unless I have group write permissions. On the server the user has uid = 1000, gid = 1000. On the client the user has uid =1699, gid = 1000. Both have the same user name.
On the client the directory listing properly shows the user name and the group name. If the file on the server is 644, the client cannot write to the file. If it is 664 on the server, then the client can write to the file.
/etc/export on server contains:
Code:
/export 172.24.84.0/24(rw,fsid=0,insecure,no_subtree_check,async)
/export/myuser 172.24.84.0/24(rw,nohide,insecure,no_subtree_check,async)
/etc/fstab on client contains:
Code:
nfsserver:/myuser /home/myuser/mntpoint nfs4 rw,noauto,user 0 0

I want to access my desktop from my laptop over the internet, after a while I found this [URL] so I followed the instructions "Access your PC over the internet" and "Logging in from another Ubuntu PC". Everything goes well until I try to run the shell script and get this: laptopuser@123.456.7.890's password:
I tried my luck with the passphrase associated with the rsa key, with the password of the laptopuser@laptop and with the password of the desktopuser@desktop but I keep getting Permission Denied (publickey, password).

I have a shared directory on another machine but I can't get it to mount as a samba share. The permission denied doesn't say where/which permission is denied. Is it on the remote on on the local machine? The remote has sharing enabled for the shareddocs directory and after I have mkdir'ed the local mount point I open it's permissions too. The verbose response from mount.cfis looks like this:
mount.cifs kernel mount options: unc=//192.168.1.102shareddocs,domain=WORKGROUP,ver=1,rw ,username=clive,,,,,,,,,,,ip=192.168.1.102,pass=** ******
mount error(13): Permission denied
Refer to the mount.cifs( manual page (e.g. man mount.cifs)
The man page does not have a list of error codes.

-xmms does support the "Expensive Hi Fi", wich as i told i've allreday installed and works.
-Xmms doesn't support the "Analog Vu Meter Plugin" for that skin, wich i don't know were to download(i only am able to see the images of it at [url]?content=49220"-3rd picture bellow, left side-the "Sony Vu's").
-The http page refers the skins and the plugin to KDE graphic environment, i'm using GNOME, and i'm not shure that this may make any difference.
-After the exausting net reading, i think...?, that Audacious does support the "Expensive Hi Fi" and the "Analog Vu Meter Plugin".
As i told, i don't give up that easy, and Audacious seems to be some upgrade or evolution of Xmms, and it as that "retro classic" look that i like and can be personalized like Xmms.
So, i've allready installed Audacios, with all the necessary codecs and libraries, and it's working so well as Xmms worked.
But know i'm having another problem :
-To personalize skins in Audacious(...more exausting net reading...), the operation should be so easy as:
-For any skin that we want(*.wal;*.wsz or compressed one's...), download it and copy it into:/users/share/audacious/Skins, wich i've allready tried(such as skins pasted into .xmms), but i get this error message:"Permission denied"!

trouble when I log in the fedora as a normal user(not root) today. When I fill the username and the password press enter key. Then pop up a little window locate at topleft corner. And have one line message : "/usr/bin/xterm : Could not exec /bin/bash : Permission Denied"hen I log in as root, it's ok. And when I open shell and type "su username" then the console print "su: /bin/bash: Permission denied"I have checked the perms of "/bin/bash" , it's 755. And I have tried all things which suggested from articles searched through Google. like change / or /root and other directory's permissions but failed

This is weird, today I updated my system and while trying to visudo from single user mode got
"cannot read /etc/shadow: Permission denied"
which kept me from doing anything until I switched to file permissions of 400 on shadow, then back. Is this being experienced by anyone else or just me? /etc/security/limits.conf doesn't seem like it wants to change in enforcing mode either and I can't find any alerts to provide clues on the situation.

I have a cron backup scheme in which I rsync, then tar, then copy files on my internal hard drives to an external (USB) drive. When it works, it works. But I often get a "Permission Denied" message for all of these tasks. how the external drive is auto-mounted so I edited the etc/fstab so that the owner of the cron job is also the owner of the external drive (I think. Unfortunately, I'm not at that machine right now (it's at work), I can't give the exact fstab line (I will post it as an update to this thread next time I am at the machine).) BUT, I still get times when the cron backup runs fine and other times I get the Permission Denied. This is a shared machine that is dual-booted, so what I *think* is going on is that when the machine is rebooted to Fedora, but nobody logs in, I get a Permission Denied for the cron backup. It seems like on days when someone has logged in as the main user and left without logging out that the cron backup runs fine.

I'm running Fedora 14, with a SATA interface CD/DVD drive and I'm attempting to run an installation script on a CD for an embedded Linux learning kit.Logged in as root (su), I receive:bash : /media/EmbeddedLinux/install_tools Permission DeniedI have searched and see similar situations on the web, but not exactly the same.I cannot resolve this issue using chmod, and find no relevant exec rights set in /etc/fstab.Using mount I find the (automounted) CD drive on /dev/sr0.I've searched quite a bit but never could find the thread that was supposedly listed in this forum.I understand that I should be able to copy the contents of the folder to my machine, then execute, but if possible I would prefer to address the real cause, not go around it.Also, where on earth will I find the location of whatever is affecting the ability to execute from an automounted media?
