 |
|
Hi,
I'm currently having a strange issue with pure-ftpd.
Whenever someone uploads a file, after about one minute, he gets disconnected from the server and in order to complete his transfer, has to re-login and resume the upload. But after another minute, he gets disconnected again. Always with the following error message in the log files:
| Code: | | [INFO] Timeout (no new data for 300 seconds) |
My /etc/conf.d/pure-ftpd is as follows:
| Code: | # Config file for /etc/init.d/pure-ftpd
##Comment variables out to disable its features, or change the values in it... ##
## This variable must be uncommented in order for the server to start ##
IS_CONFIGURED="yes"
## FTP Server,Port (separated by comma) ##
## If you prefer host names over IP addresses, it's your choice :
## SERVER="-S ftp.rtchat.com,21"
## IPv6 addresses are supported.
## !!! WARNING !!!
## Using an invalid IP will result in server not starting and reporting
## a good start. Work is being done to solve that in:
## http://bugs.gentoo.org/show_bug.cgi?id=75861
#SERVER="-S 192.168.0.1,21"
SERVER="-S 85.10.200.171,2121"
## Number of simultaneous connections in total, and per ip ##
MAX_CONN="-c 100"
MAX_CONN_IP="-C 2"
## Start daemonized in background ##
DAEMON="-B"
## Don't allow uploads if the partition is more full then this var ##
DISK_FULL="-k 90%"
## If your FTP server is behind a NAT box, uncomment this ##
#USE_NAT="-N"
## Authentication (others are 'pam', ...)##
## Further infos in the README file.
AUTH="-l pam"
## Change the maximum idle time. (in minutes. default 15)
TIMEOUT="-I 5'"
## Use that facility for syslog logging. It defaults to 'ftp'
## Logging can be disabled with '-f none' .
#LOG="-f facility"
## Misc. Others ##
MISC_OTHER="-0 -4 -A -E -H -L 32000:16 -O stats:/var/log/pureftpd.log -u 100 -U 117:007 -w -Y 2"
#
# Use these inside $MISC_OTHER
# More can be found on "http://pureftpd.sourceforge.net/README"
#
# -A [ chroot() everyone, but root ]
# -e [ Only allow anonymous users ]
# -E [ Only allow authenticated users. Anonymous logins are prohibited. ]
# -i [ Disallow upload for anonymous users, whatever directory perms are ]
# -j [ If the home directory of a user doesn't exist, auto-create it ]
# -M [ Allow anonymous users to create directories. ]
# -R [ Disallow users (even non-anonymous ones) usage of the CHMOD command ]
# -x [ In normal operation mode, authenticated users can read/write
# files beginning with a dot ('.'). Anonymous users can't, for security reasons
# (like changing banners or a forgotten .rhosts). When '-x' is used, authenticated
# users can download dot-files, but not overwrite/create them, even if they own
# them. ]
# -X [ This flag is identical to the previous one (writing
# dot-files is prohibited), but in addition, users can't even *read* files and
# directories beginning with a dot (like "cd .ssh"). ]
# -D [ List files beginning with a dot ('.') even when the client doesn't
# append the '-a' option to the list command. A workaround for badly
# configured FTP clients. ]
# -G [ Disallow renaming. ]
# -d [ Send various debugging messages to the syslog. ONLY for DEBUG ]
# -F <fortune file> [ Display a fortune cookie on login. Check the README file ]
# -H [ By default, fully-qualified host names are logged. The '-H' flag avoids host names resolution. ] |
I already have tried to set different timeout options, the result is always the same, only the error message changes to the amount of seconds I have set in the config file.
If anyone ever experienced the same weirdness and knows a solution to it, I'm happy to get it.  |

this may be a reverse dns lookup problem.
once i had to disable reverse lookup on a similar problem.
when source attached to ftp a reverse lookup is executed
and if not able to resole hangs the traffic? just a guess. |

| Hmm, shouldn't be an issue, I've set the -H flag. |
