the version of vsftpd i read is 1.2.1， i find the following code in main.c: struct vsf_sysutil_statbuf* p_statbuf = 0; but i cannot find the definition of this structure.then anybody here can tell me what is the definition of vsf_sysutil_statbuf struct?
View 5 RepliesBefore anyone panics, the source tarball for Slackware 13.37 doesn't appear to be the "bad" tarball that Chris Evans mentions here:

I checked str.c for the call to vsf_sysutil_extra() if the user is specified as and I also checked for the rogue shellcode in sysdeputil.c but I didn't find it, so it looks like the backdoor was uploaded recently.

Chris Evans, aka Scary Beasts, has confirmed that version 2.3.4 of vsftpd's downloadable source code was compromised and a backdoor added to the code. Evans, the author of vsftpd - which is described on its web site as "probably the most secure and fastest FTP server for Unix-like systems" - was alerted on Sunday to the fact that a bad tarball had been downloaded from the vsftpd master site with an invalid GPG signature. It is not known how long the bad code had been online.
The bad tarball included a backdoor in the code which would respond to a user logging in with a user name "" by listening on port 6200 for a connection and launching a shell when someone connects.Evans has now moved the source code and site to [URL] a Google App Engine hosted site. The GPL-licensed source code can be downloaded (direct download) from the same site, along with the GPG signature for validating the download, a step that Evans recommends. Evans says that the lack of obfuscation and lack of victim identification leads him to believe that "perhaps someone was just having some lulz instead of seriously trying to cause trouble".
I just want to configure Vsftpd to allow users to have total access to the FTP server. The server and users are all on a private LAN behind a router with no access from the Net, so I don't need any security. The following basic configuration doesn't allow uploading files after I log on as anonymous/whatever:
/etc/vsftpd/vsftpd.conf
Code:
listen=YES
anonymous_enable=YES
local_enable=YES
write_enable=YES
xferlog_file=YES
#anonymous users are restricted (chrooted) to anon_root
#anon_root=/home/ftp/incoming
anon_root=/var/ftp
anon_upload_enable=YES
anon_mkdir_write_enable=YES
#chroot_local_user=NO
#chroot_list_enable=YES
#chroot_list_file=/etc/vsftpd.chroot_list
Here's what happens when I log on as anonymous/whatever and try to upload a file:

I am a beginner in ubuntu and only recently did i install Ubuntu 10.10 using Wubi. I am dual booting along with Windows 7 64bit. Before I got to know of Wubi, I created a free 20GB partition for installing linux. But since it was of no use, I decided to extend another partition adding this 20GB space. The problem now is that I am getting the following error while trying to access the partition.
"Error mounting: mount exited with exit code 12: Failed to read last sector (605949951): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
or it was not setup correctly (e.g. by not using mdadm --build ...),
or a wrong device is tried to be mounted,
or the partition table is corrupt (partition is smaller than NTFS),
or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/sda5': Invalid argument
The device '/dev/sda5' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?"
These are the results after running sudo fdisk -l /dev/sda:

I have a server listening on incoming client connections. Once the client establishes SSL connection with the server, the server waits on read() from the client. Only Client can disconnect the connection. I want to have a timer in the server program to wait for x secs after read() and then disconnect the Client connection.

View 1 Replies View RelatedI am working on a project with a lot of vector math and I'd like to find a way to speed it up.eading about SSE, but I've found no explanation on how to actually use it in code (was looking for some kind of hello-world example, complete with compilation instructions).Does the gcc compiler automatically make use of SSE, if you add the -sse(2,3) option on the command line? Or are their specific functions/libraries you need to call?
View 12 Replies View RelatedIs there, by chance, a fancy name to describe code that must be in a program but will never be executed? In one of my (Haskell) programs, I have some error-handling code that must be in the program to keep the compiler happy (due to the type checking). However I know that, due to the logical structure of the program, it is impossible for the code to be evaluated. I am curious if there is a technical name given to code that must exist but cannot be executed.
