a2disconf

commands. A2enconf is a script that enables the configuration file specified within the Apache2 configuration. It does this by creating symbolic links within /etc/apache2/conf-enabled. Similarly, a2disconf disables a specific configuration part by removing those symbolic links. It is not a mistake to enable a setting that is already enabled, or to disable one that is already disabled. Note that many configuration files may have a dependency on specific modules. Unlike module dependencies, they are not resolved automatically. Configuration fragments stored in the conf-available directory are considered non-essential or are being installed and managed by reverse dependencies (e.g. web scripts). OPTIONS -q, -quiet Do not display informational messages. -m, -maintmode Enables maintainer mode, that is, the invocation of the program is done automatically by a maintainer script. This switch should not be used by end users. -p, -purge When disabling a module, purge all traces of the module in the internal state database.

check_forensic

Tool

to extract mod_log_forensic output from apache log files [email protected]:~# man check_forensic check_forensic(8) System Administrator’s Manual check_forensic(8) NAME check_forensic – tool to extract mod_log_forensic output from Apache log files SYNOPSIS check_forensic <log_file> DESCRIPTION chech_forensic is a simple shell script designed to help Apache administrators extract mod_log_forensic output of the Apache2 log files. Check the forensic log for requests that were not completed and place the request log for each. This manual page was written by Fabio M. Di Nitto <[email protected] bione.net>, for the Debian GNU/Linux system (but can be used by others). check_forensic(8) checkgid Check the gid[email protected]:~# man checkgid CHECKGID(8) CHECKGID System Administrator’s Manual(8) NAME checkgid – check the

gid

SYNOPSIS checkgid group DESCRIPTION This page of the manual briefly documents the

checkgid

command. CheckGid is a program that checks whether you can set the specified group. This is to see if it is a valid group for apache2 to use at runtime. If the user (must run as superuser) is in that group, or can be configured in it, it will return 0. This manual page was written by Daniel Stone <[email protected]> for the Debian GNU/Linux distribution, as the original did not have a manual page. November 3rd, 2001 CHECKGID(8) fcgistarter

Usage: htcacheclean [-Dvtrn] -pPATH [-lLIMIT] [-LLIMIT] [-PPIDFILE] htcacheclean [-nti] -dINTERVAL -pPATH [-lLIMIT] [-LLIMIT] [-PPIDFILE] htcacheclean [-Dvt] -pPATH URL … Options: -d Daemonize and repeat cache cleaning every INTERVAL minutes. This option is mutually exclusive with the -D, -v and -r options. -D Do a dry run and don’t eliminate anything. This option is mutually exclusive with the -d option. When doing a dry run and deleting directories with -t, the reported inodes deleted in the statistics cannot take into account the deleted directories, and will be marked as an estimate. -v Be detailed and print statistics. This option is mutually exclusive with the -d option. -r Clean thoroughly. This assumes that the Apache web server is not running. This option is mutually exclusive with the -d option and implies -t. -n Be nice. This causes slower processing in favor of other processes. -t Delete all empty directories. By default, only cache files are deleted, however, with some settings, the large number of directories created may require attention. -p Specify PATH as the root directory of the disk cache. -P Specify PIDFILE as the file to write the pid to. -R Specify the amount to round up to. -l Specify LIMIT as the total size limit of the disk cache. Attach ‘K’, ‘M’, or ‘G’ to the number to specify KBytes, MBytes, or GBytes. -L Specify LIMIT as the total limit of disk cache inodes. The suffixes ‘K’, ‘M’ or ‘G’ can also be used. -i Be smart and run only when there was a modification of the disk cache. This option is only possible in conjunction with the -d option. -a List currently cached URLs. Variants of the same URL will be listed once for each variant. -A List the URLs currently stored in the cache, along with their attributes in the following order: url, header size, body size, status, entity version, date, expiration, request time, response time, body present, header request. If a URL is provided on the command line, the URL will be deleted from the cache. A reverse proxy URL consists of the following: http://<hostname>:<port><path>? [Consult]. So, for the path “/” on the host “localhost” and port 80, the URL to be removed becomes “http://localhost:80/?”. Note that the ‘?’ in the URL must always be explicitly specified, whether a query string is present or not. htdbm Manipulate DBM password databases[email protected]:~# htdbm -h htdbm: illegal option – h

Usage: htdbm [-cimBdpstvx] [-C cost] [-TDBTYPE] database username -b[cmBdptsv] [-C cost] [-TDBTYPE] database username password -n[imBdpst] [-C cost] username -nb[mBdpst] [-C cost] username password -v[imBdps] [-C cost] [-TDBTYPE] database username -vb[mBdps] [-C cost] [-TDBTYPE] database username password -x [-TDBTYPE] database username – l [-TDBTYPE] database Options: -c Create a new database. -n Do not update the database; Show results in STDOUT. -b Use the password from the command line instead of prompting for it. -I read the stdin password without verification (for the use of scripts). -m Force MD5 encryption of the password (default). -B Force BCRYPT encryption of password (very secure). -C Set the calculation time used for the bcrypt algorithm (higher is safer but slower, default: 5, valid: 4 to 31). -d Force CRYPT encryption of the password (8 characters maximum, insecure). -s Force SHA encryption of the password (insecure). -p Do not encrypt the password (plain text, insecure). -T DBM Type (SDBM| GDBM| DB|default). -l Display database user names in stdout. -v Verify the username/password. -x Delete the user name record from the database. -t The last parameter is the user name comment. The SHA algorithm does not use a salt and is less secure than the MD5 algorithm.

htdigest

rotatelogs

Pipelined log program to rotate Apache

logs[email protected]:~# rotatelogs -h rotatelogs: illegal option – h Usage: rotatelogs [-v] [-l] [-L linkname] [-p prog] [-f] [-D] [-t] [-e] [-c] [-n number] <logfile> {<rotation time in seconds>|<rotation size>(B| K| M|G)} [minute offset from UTC] Add this: TransferLog “|rotatelogs /some/where 86400” or TransferLog “|rotatelogs /some/where 5M” to httpd.conf. By default, the generated name will be <logfile>.nnnn where nnnn is the system time at which logging is nominally started (N.B. if a rotation time is used, the time will always be a multiple of the rotation time, so you can synchronize cron scripts with it). If <logfile> contains strftime conversion specifications, they will be used instead. At the end of each rotation time or when the file size is reached, a new record is started. Options: -v Detailed operation. Messages are written in stderr. -l Base the rotation in local time instead of UTC. -L path Create hard link from the current record to the specified path. -p prog Run the specified program after opening a new log file. See below. -f Force open the program login. -D Create parent directories of the log file. -t Truncate log file instead of spinning, queue friendly. -e Echo recording to stdout for further processing. -c Create record even if it is empty. -n num Rotate file by adding the suffixes ‘.1’, ‘.2’, …, ‘.num’. The program for ‘-p’ is invoked as “[prog] <curfile> [<prevfile>]” where <curfile> is the name of the newly opened log file, and <prevfile>, if given, is the file name of the previously used log file.

split-logfile

Split access to mixed virtual hosts log in to one file per virtual host[email protected]:~# man split-logfile SPLIT-LOGFILE(8) split-logfile SPLIT-LOGFILE(8) NAME split-logfile –

Split the access log to combined virtual hosts into one file per virtual host

SYNOPSIS split-logfile < logfile SUMMARY This script will take a combined web server access log file and split its contents into separate files. It is assumed that the first field on each line is the identity of the virtual host (put there by “%v”), and that the log files should be named that+”.log” in the current directory. The merged log file is read from stdin. Read logs will be mapped to any existing log file.
