Linux – vsftpd file uploading fail

ftplinux

I have a Lenny server with vsftpd as ftp server.
I have to upload a lot of jgps files, each named like this:

05-09-2010-01.jpg
05-09-2010-02.jpg
….

until

05-09-2010-40.jpg

My problem is that the file "05-09-2010-17.jpg" (seventeen) fails! if I try to upload manually fails too. The only way is rename it, then upload to the remote server.

The client Ubuntu with LVM partitions.

I'm using the command line ftp client (because I use it in a script)

any ideas?!

Maybe there is an existing file with that same name in the same directory, and possibly it is owned by a user that vsftpd can't write over. Also, if I recall correctly, I think you can limit upload size in vsftpd.conf; maybe it is set too low.

Ftp – How to tell SELinux to give vsftpd write access in a specific directory

# semanage fcontext -a -t public_content_rw_t "/myftp/pub(/.*)?"

Be sure to include the (/.*)? at the end of the directory name.

I also tried to use audit2allow to generate a policy, but what it does is generate a policy that gives ftpd write access to directories of type public_content_t; this is equivalent to turning on allow_ftpd_full_access, if I understood it correctly

Essentially, yes; since SELinux allows directories/files labeled with public_content_t to be shared between different services. However, further access control is in place through the use of sebooleans (or sebool, more precisely).

Giving "ftpd full access", doesn't mean giving it the rights to do/read/write what and where it wants. SELinux has designated policies in place for the services on your system; meaning, ftpd is allowed to read files if the directory's file context (fcontext) is public_content_t. SELinux gives write permissions to the ftp server if the directory's fcontext is public_content_rw_t; other services such as samba, apache, etc. have to be allowed write permissions to those directories through the booleans, according to the pertaining RedHat Documentation. If your "local policy" gives ftpd write access in directories labelled public_content_t, it essentially strips away a layer of security. Therefore, I suggest labeling the directory with the public_content_rw_t context, and removing your custom generated local policy.

For further information and details, please see the SELinux wiki pages.

Linux – vsftpd fast for binary files, slow for text files

Maybe the line-ending conversions in vsftpd were written inefficiently, and since binary mode is most commonly used, no one has bothered to improve the algorithm used in vsftpd.

Or, it could just be that passing data from a tcp socket out to disk really is a lot faster than having to check every character for CR and LF. The check could introduce enough latency in the connection to reduce your transfer speed.

Are you running tests locally on Ethernet (low latency, would be affected greatly by additional latency) or across the Internet?
