Troubleshoot FTP

When done, it'll look a whole lot like the "Troubleshoot TFTP" article in structure.

Testing FTP
Try to get a file with Linux:
These commands are NOT done on your FOG server, they are done on another Linux machine (this example uses Fedora).
To explain what's happening below in the code box,
- Create a test file with some data in it to send later.
- Start ftp (may need installed first).
- Open connection to FOG server.
- Provide username.
- Provide password.
- Change to /images directory.
- List directory contents.
- Upload file.
- List directory contents to verify.
- Download the file.
- Delete the file.
- Exit ftp.

Try to get a file with Windows:

Creating & verifying .mntcheck files
.mntcheck is a hidden and empty file that FOG uses to verify a NFS share is mounted correctly.
To create these files, on the FOG server:
touch /images/.mntcheck touch /images/dev/.mntcheck
Verify these files with:
ls -laR /images | grep .mntcheck
This should return two results. One for /images and one for /images/dev
FTP Service
Fedora 20/21
- Check the status of FTP with
systemctl status vsftpd.service(should be on and green, no errors, and enabled)
- stop, start, disable and enable FTP service.
systemctl stop vsftpd.service systemctl start vsftpd.service systemctl disable vsftpd.service systemctl enable vsftpd.service
- Test that it’s functioning by using the testing instructions at the top of this article
ftp://x.x.x.x
- Use fog / your-fog-account-Password for the credentials
- You should see “Index of /”
Ubuntu

FTP Settings File
Fedora 21:
Location:
/etc/vsftpd/vsftpd.conf
To display file:
cat /etc/vsftpd/vsftpd.conf
It should look a lot like this:
anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 dirmessage_enable=YES xferlog_enable=YES connect_from_port_20=YES xferlog_std_format=YES listen=YES pam_service_name=vsftpd userlist_enable=NO tcp_wrappers=YES seccomp_sandbox=NO
To edit:
vi /etc/vsftpd/vsftpd.conf
Explanation of settings:

Troubleshooting here.
Disable/verify Firewall
Disable & Stop Firewall in Fedora 20/21
systemctl disable firewalld.service
systemctl stop firewalld.service
Can be undone with "start" and "enable".
Check Firewall in Fedora 20/21
systemctl status firewalld.service
Fedora 16
Add /bin/bash to /etc/shells as the vsftpd yum install does not do it correctly causing tftp timeout message
Check Firewall in Debian/Ubuntu
sudo iptables -L
If disabled, the output should look like this:
Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination
Disable Ubuntu Firewall
sudo ufw disable
Disable Debian Firewall
iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X iptables -P INPUT ACCEPT iptables -P OUTPUT ACCEPT iptables -P FORWARD ACCEPT
Temporarily disable Windows firewall
Permissions
The credentials used for this:
Storage Management -> Storage Node -> Management Username / Management Password
Should exactly match the ownership of the /images directory and all of it's contents.
ls -laR /images
(add comparative picture here, with the ownership and username highlighted and linked, with the text "Should be the same")
Common problems and fixes
Images won't finish uploading, won't go past "Clearing ntfs flag"
This is permissions related. See forum threads for more details:
stuck-after-clearning-ntfs-flag
imaging-stuck-on-upload-after-finished
List permissions:
ls -laR /images
Fix permissions: Use the correct OS user, and correct storage node password to change ownership and give read/write/execute to everyone. Assumes user is "fog".
chown fog -R /images chmod -R 777 /images
Changing ownership with user AND group (replace "user" and "group" with actual values):
chown user:group -R /images
