Is there a trick to allowing a TFTP connection to create a file? I can successfully tftfp (from a cisco router) if I touch the file first, but otherwise, (/tftpboot has been chmoded to 777) I get [TFTP: error code 2 received - 20334]

I'm trying to setup a network boot server and I'm having an issue with tftp. In the /etc/xinetd.d/tftp file, I added the "-v" (verbose) option to the server arg line so that i could figure out what was happening. When i looked at the /var/log/messages log file, it let me know that permission was denied to /tftpboot/nbi_img.
So, in short, my problem is that tftp isn't working because it doesn't have permission to /tftpboot/nbi_img. I can't figure out why. I stumbled upon a site where the user figured out a temporary fix to this issue and what he did was disabled the xinetd service and typed the following command:/usr/sbin/in.tftpd -l -v -v -s /tftpboot/nbi_imgWhen I do this as well, it works! but only until I restart and then I have to do that again. Is there a way to be able to fix that for good?
I was able to install and start tftp.I can tftp localhost and get a file, even from a non-administrator login.I can connect from a remote host, but the *get* times out.I suspect there is a security issue. Can you tell me how to lower the security on tftp so that a remote host can do gets?

I am trying to wade through the semanage jungle to get permissions for a tftp client. I followed the HowTos [URL] but I get the following at the client:
tftp> status
Connected to 192.168.1.101.
Mode: netascii Verbose: off Tracing: off
Rexmt-interval: 5 seconds, Max-timeout: 25 seconds
tftp> get hello.o4
tftp: hello.o4: Permission denied
I finally figured out that the firewall directives shown at the end of the HowTo refer to semanage although the options are stated incorrectly according to the man page for semanage. I did insure that the file hello.o4 in /tftpboot has read permission for everybody.
I have a problem installing CentOS 5.5 over lan. I set up a dhcp3 server and it works, client got an ip. I set up a tftpd-hpa server and it works, client can boot the install image of CentOS 5.5 I set up an apache server and it seems to be impossible... In the installation marathon I clicked through the menu to the choice of the web server where my installation files are available. I enter the ip 192.168.138.1 and the path CentOS-5.5 and CentOS tells me "Unable to retrieve http://192.168.138.1//CentOS-5.5/images/stage2.img" . Thats right because the two slashes are not right. Where the hell come the two slashes from???
I edited my httpd.conf like this:
<Directory /tftpboot/CentOS-5.5>
Options Indexes
AllowOverride None
</Directory>

I am trying to put a file from one linux machine to my other linux machine. There is absolutely no problem in downloading the file i.e. performing the "get" operation but when I try to upload or "put file" from my host1 to host2 it throws error "Error 0 Permission denied". I am able to put files from host2 to host1 without any problem but not from host1 to host. Infact if I try to tftp even localhost on host2 it throws the same error. Here is my
/etc/xinetd.d/tftp file for host2
service tftp {
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -c -s /tftpboot
#disable = yes
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
And permissions on /tftpboot are 777
[root@LinuxServer /]# ls -ld /tftpboot/
drwxrwxrwx 2 root root 4096 Jan 6 05:21 /tftpboot/
[root@LinuxServer /]# ls -l /tftpboot/
total 16
-rwxrwxrwx 1 root root 11 Jan 6 06:16 new_test
-rwxrwxrwx 1 root root 12 Jan 5 06:02 test2
And the command which I am using is :
[root@LinuxServer /]# tftp localhost -c put new_test
Error code 0: Permission denied
And ya here is /etc/sysconfig/selinux file is as under :
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=permissive
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.

I'm a PHP developer and an app I'm working on right now generates files for users to download. The problem I'm seeing is in order to write to a folder I have to chmod it 777, obviously a bad idea.
I'm thinking the best idea is to change the folder user / group to that of apache, however after over an hour of Googleing I can not find out what user / group apache belongs to.
Thoughts? Is this the best way to go or should I do something else?

View 1 Replies View RelatedI am downloading some files via tftp from the server (call it my server) and I need the server to be case insensitive to the file names requested. That is If I request "SoMe.TTL" and the actual file name is "some.ttl" it should send "some.ttl" back! Right now it is case sensitive and is a pain in the but because some windows clients upload files to that directory and the names can have any case. Furthermore, the file request mechanism must allow the user to input the required file name, hence the user can write using any case. Can the tftp-server solve cases by it's own? How about dnsmasq's internal tftp server? Ok, maybe I wasn't explicit above:

I have installed CentOS 5.5 along with the Samba package. I have it configured (i believe), but when I try to access a share, it is not accepting my UN/PW. I have copied the smb.conf file from a working computer over to this one, but it is still not accepting my login. Anyone know of any other files I should check?
I have moved a working smb.conf file to this new box, and both computers have the same UN/PW's

View 2 Replies View RelatedWhat I am trying to to is set up a cluster as follows:
- There are four nodes
- Nodes three and four have large amounts of storage that will be used for storing user data.
- Nodes one and two will be running a couple of network services.
I'd like have nodes one and two to have a clustered filesystem just between them to store data for the services run only by them.is it possible to share one filesystem between two nodes and another filesystem between two other nodes? The cluster seems to try to make the storage changes across all nodes. They will not be able to spend the extra money to get the same storage in all four nodes. Here is what I have done. I am using CentOS 5.5. After installing CentOS, I did this:
On all nodes:
Code:
[root@node1 ~]# yum groupinstall "Clustering"
[root@node1 ~]# yum groupinstall "Cluster Storage"
[root@node1 ~]# chkconfig ricci on
[code].....
...which I think makes sense because the cluster was supposed to create the PV and the volume group, but did not. I don't even think it tries. The first time it tries to do anything to another node is when I create a logical volume.
Are there any general recommendations on skipping creation of swap partition on servers? If I am sure that server will be ok with it's RAM is there any benefit in skipping swap partition creation or making it the least size possible other than saving disk space?

View 4 Replies View RelatedI've hit a wall here; I'm attempting to find some way by which to view files and cd into directories on a device mounted read-only. So I need the permissions to read, write, execute (and the same with directories), but chmodding is out of the question because I don't want to alter the drive one iota.
I guess what I could do--what I was thinking of initially--was to dupe the whole drive and then mess with permissions. This wouldn't affect the original (actually I'm working on a duplicate of the original, but I'm treating it as if it were the original) but I was hoping for something that would maintain data integrity. This is a forensic application and not altering the data is very important.
1. I use RHEL5 (SERVER X) in which samba is running. This is an IBM hardware on which the vender is not allowing me to install any hardware other than IBM parts.
2. I have another P4 system on which Fedora Core 11 (SERVER Y) is running. I had connected 300GB SCSI HDD and created necessary partitions.
Now I want to mount few of the volumes of SERVER Y on SERVER X and allow users (samba clients) to access the volumes as folders as any other volumes in SERVER X through samba. I mounted one volume of SERVER Y in SERVER X using NFS mounting and shared through samba. The problem, I am facing, is it is very slow.
I am experiencing poor performance when using cifs share.Such poor performance occur only in the creation of files on the share but not in the rewrite.This is what i do:

View 1 Replies View RelatedI'm trying to install Ubuntu alongside windows 7 on my machine, and currently I am having difficulty doing so.Upon initial boot of the LiveCD,it says the installer has encountered an unrecognized error and just goes straight to desktop environment. From there, I can restart the installer just fine but here is where the trouble starts.
Currently, I have a 2TB RAID 0 array utilizing 4 500GB Seagate barracuda SATA II drives. The controller is an nForce 780a NVRaid. I currently have two NTFS partitions for windows. One 150GB primary partition for C:, and another 781GB D: for the storage of games, music and movies.When I try to manually setup the partitions in the Ubuntu installer, I do it like this.
- 200MB ext2 primary partition for /boot
- 150GB xfs logical partition for /
- approx 750GB xfs logical partition for /home (You've probably figured out I'm following the same C: and D: scheme as in windows)
- 8192 MB partition for swap
I then proceed with the install. I see the progress bar complete for the boot partition, but then at about 7% for / it stops and gives a message saying partition creation has failed. I even tried using different filesystems like ReiserFS and Ext4. Same thing every time. I am running a 64bit quadcore system BTW if that is of any importance.
