[dovecot] login

Post by martin durnthaler » 2005-08-05 14:38

hallo zusammen,

ich versuche schon seit längerer zeit dovecot auf meinem fc3-server zum laufen zu bringen. postfix funktioniert bereits (intern und extern), das problem ist jedoch, dass ich mich weder per imap noch per pop3 am server anmelden kann um die mail abzurufen.

der log-auszug sieht so aus:

Code: Select all

Aug  5 14:28:49 vs150137 dovecot: Killed with signal 15

ich weiß nicht mehr wirklich weiter und hoffe, dass einer von euch eine idee hat.

Hmm, kill mal den dovecot und schau nach, ob noch Prozesse (dovecot-login) überbleiben.
Via netstat kannste auch noch nachschauen, ob evtl. noch dovecot-Prozesse ein paar FIFOs offen haben.

Wenn wirklich kein Prozess mehr da ist (von dovecot), und es nach Start des Dienstes immernoch nicht klappt, musst du mal deine dovecot.conf posten.

hi,

ausser dovecot läuft kein anderer prozess mehr, aber ich hab grad entdeckt, dass beim starten von dovecot die folgende meldung im maillog erscheint.

Aug 9 05:38:43 dovecot: Dovecot v1.0-test59 starting up
Aug 9 05:38:44 dovecot: net_connect_unix(/var/run/dovecot/auth-master) failed: No such file or directory
Aug 9 05:38:44 dovecot: BUG: Authentication server sent invalid SPID (14402 != 14947)
Aug 9 05:38:44 dovecot: Auth process died too early - shutting down

werd dovecot nochmal neu installieren und mich dan wieder melden.

einstweilen danke für die hilfe.

mfg,
martin durnthaler

die neuinstallation hat leider nichts gebracht, hier ist meine dovecot.conf:

Code: Select all

## Dovecot 1.0 configuration file

# '#' character and everything after it is treated as comments. Extra spaces
# and tabs are ignored. If you want to use either of these explicitly, put the
# value inside quotes, eg.: key = "# char and trailing whitespace  "

# Default values are shown after each value, it's not required to uncomment
# any of the lines. Exception to this are paths, they're just examples
# with real defaults being based on configure options. The paths listed here

# possible to specify multiple addresses. "*" listens in all IPv4 interfaces.
# "[::]" listens in all IPv6 interfaces, but may also listen in all IPv4
# interfaces depending on the operating system. You can specify ports with
# "host:port", although with multiple protocols you probably want to move this
# setting inside protocol imap/pop3 { ... } section, so you can specify
# different ports for IMAP/POP3.
listen = *

# IP or host address where to listen in for SSL connections. Defaults
# to above if not specified.
#ssl_listen =

# Disable SSL/TLS support.
ssl_disable = yes

# Disable LOGIN command and all other plaintext authentications unless

##
## Login processes
##

# Set max. process size in megabytes. If you don't use
# login_process_per_connection you might need to grow this.
#login_process_size = 32

# Should each login be processed in it's own process (yes), or should one
# login process be allowed to process multiple connections (no)? Yes is more
# secure, espcially with SSL/TLS enabled. No is faster since there's no need
# to create processes all the time.
#login_process_per_connection = yes

# Number of login processes to create. If login_process_per_user is
# yes, this is the number of extra processes waiting for users to log in.
#login_processes_count = 3

# Maximum number of extra login processes to create. The extra process count
# usually stays at login_processes_count, but when multiple users start logging
# in at the same time more extra processes are created. To prevent fork-bombing
# we check only once in a second if new processes should be created - if all
# of them are used at the time, we double their amount until limit set by this
# setting is reached. This setting is used only if login_process_per_use is yes.
#login_max_processes_count = 128

# Maximum number of connections allowed in login state. When this limit is
# reached, the oldest connections are dropped. If login_process_per_user
# is no, this is a per-process value, so the absolute maximum number of users
# logging in actually login_processes_count * max_logging_users.
#login_max_logging_users = 256

# Greeting message for clients.
#login_greeting = Dovecot ready.

##
## Mail processes
##

# Maximum number of running mail processes. When this limit is reached,
# new users aren't allowed to log in.
#max_mail_processes = 1024

# Show more verbose process titles (in ps). Currently shows user name and
# IP address. Useful for seeing who are actually using the IMAP processes
# (eg. shared mailboxes or if same uid is used for multiple accounts).
#verbose_proctitle = no

# Show protocol level SSL errors.
#verbose_ssl = no

# Valid UID range for users, defaults to 500 and above. This is mostly
# to make sure that users can't log in as daemons or other system users.
# Note that denying root logins is hardcoded to dovecot binary and can't
# be done even if first_valid_uid is set to 0.
#first_valid_uid = 500
#last_valid_uid = 0

# Valid GID range for users, defaults to non-root/wheel. Users having
# non-valid GID as primary group ID aren't allowed to log in. If user
# belongs to supplementary groups with non-valid GIDs, those groups are
# not set.
#first_valid_gid = 1
#last_valid_gid = 0

# Grant access to these extra groups for mail processes. Typical use would be
# to give "mail" group write access to /var/mail to be able to create dotlocks.
#mail_extra_groups =

# ':' separated list of directories under which chrooting is allowed for mail
# processes (ie. /var/mail will allow chrooting to /var/mail/foo/bar too).
# This setting doesn't affect login_chroot or auth_chroot variables.
# WARNING: Never add directories here which local users can modify, that
# may lead to root exploit. Usually this should be done only if you don't
# allow shell access for users. See doc/configuration.txt for more information.
#valid_chroot_dirs = 

# Default chroot directory for mail processes. This can be overridden for
# specific users in user database by giving /./ in user's home directory
# (eg. /home/./user chroots into /home). Note that usually there is no real
# need to do chrooting, Dovecot doesn't allow users to access files outside
# their mail directory anyway.
#mail_chroot = 

# Default MAIL environment to use when it's not set. By leaving this empty
# dovecot tries to do some automatic detection as described in
# doc/mail-storages.txt. There's a few special variables you can use, eg.:
#
#   %u - username
#   %n - user part in user@domain, same as %u if there's no domain
#   %d - domain part in user@domain, empty if there's no domain
#   %h - home directory
#
# See doc/variables.txt for full list. Some examples:
#
#   default_mail_env = maildir:/var/mail/%1u/%u/Maildir
#   default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u
#   default_mail_env = mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n
#
default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u

# If you need to set multiple mailbox locations or want to change default
# namespace settings, you can do it by defining namespace sections:
#
# You can have private, shared and public namespaces. The only difference
# between them is how Dovecot announces them to client via NAMESPACE
# extension. Shared namespaces are meant for user-owned mailboxes which are
# shared to other users, while public namespaces are for more globally
# accessible mailboxes.
#
# REMEMBER: If you add any namespaces, the default namespace must be added
# explicitly, ie. default_mail_env does nothing unless you have a namespace
# without a location setting. Default namespace is simply done by having a
# namespace with empty prefix.
#namespace private {
   # Hierarchy separator to use. You should use the same separator for all
   # namespaces or some clients get confused. '/' is usually a good one.
   #separator = /

   # Prefix required to access this namespace. This needs to be different for
   # all namespaces. For example "Public/".
   #prefix = 

   # Physical location of the mailbox. This is in same format as
   # default_mail_env, which is also the default for it.
   #location =

   # There can be only one INBOX, and this setting defines which namespace
   # has it.
   #inbox = yes

   # If namespace is hidden, it's not advertised to clients via NAMESPACE
   # extension or shown in LIST replies. This is mostly useful when converting
   # from another server with different namespaces which you want to depricate
   # but still keep working. For example you can create hidden namespaces with
   # prefixes "~/mail/", "~%u/mail/" and "mail/".
   #hidden = yes
#}

# Space-separated list of fields to initially save into cache file. Currently
# these fields are allowed:
#
#  flags, date.sent, date.received, size.virtual, size.physical
#  mime.parts, imap.body, imap.bodystructure
#
# Different IMAP clients work in different ways, so they benefit from
# different cached fields. Some do not benefit from them at all. Caching more
# than necessary generates useless disk I/O, so you don't want to do that
# either.
#
# Dovecot attempts to automatically figure out what client wants and it keeps
# only that. However the first few times a mailbox is opened, Dovecot hasn't
# yet figured out what client needs, so it may not perform optimally. If you
# know what fields the majority of your clients need, it may be useful to set
# these fields by hand. If client doesn't actually use them, Dovecot will
# eventually drop them.
#
# Usually you should just leave this field alone. The potential benefits are
# typically unnoticeable.
#mail_cache_fields = 

# Space-separated list of fields that Dovecot should never save to cache file.
# Useful if you want to save disk space at the cost of more I/O when the fields
# needed.
#mail_never_cache_fields = 

# Like mailbox_check_interval, but used for IDLE command.
#mailbox_idle_check_interval = 30

# Allow full filesystem access to clients. There's no access checks other than

# to create new keywords.
#mail_max_keyword_length = 50

# take less CPU, especially with sendfile() syscall with Linux and FreeBSD.
# But it also creates a bit more disk I/O which may just make it slower.
#mail_save_crlf = no

# Use mmap() instead of read() to read mail files. read() seems to be a bit
# faster with my Linux/x86 and it's better with NFS, so that's the default.
# Note that OpenBSD 3.3 and older don't work right with mail_read_mmaped = yes.
#mail_read_mmaped = no

# Don't use mmap() at all. This is required if you store indexes in remote
# filesystems (NFS or clustered filesystem).
#mmap_disable = no

# Don't write() to mmaped files. This is required for some operating systems
# which use separate caches for them, such as OpenBSD.
#mmap_no_write = no

# Locking method for index files. Alternatives are fcntl, flock and dotlock.
# Dotlocking uses some tricks which may create more disk I/O than other locking
# methods.
#lock_method = fcntl

# By default LIST command returns all entries in maildir beginning with dot.
# Enabling this option makes Dovecot return only entries which are directories.
# This is done by stat()ing each entry, so it causes more disk I/O.
# (For systems setting struct dirent->d_type, this check is free and it's
# done always regardless of this setting)
#maildir_stat_dirs = no

# Copy mail to another folders using hard links. This is much faster than
# actually copying the file. This is problematic only if something modifies
# the mail in one folder but doesn't want it modified in the others. I don't
# know any MUA which would modify mail files directly. IMAP protocol also
# requires that the mails don't change, so it would be problematic in any case.
# If you care about performance, enable it.
#maildir_copy_with_hardlinks = no

# Which locking methods to use for locking mbox. There's four available:
#  dotlock: Create <mailbox>.lock file. This is the oldest and most NFS-safe
#           solution. If you want to use /var/mail/ like directory, the users
#           will need write access to that directory.
#  fcntl  : Use this if possible. Works with NFS too if lockd is used.
#  flock  : May not exist in all systems. Doesn't work with NFS.
#  lockf  : May not exist in all systems. Doesn't work with NFS.
#
# You can use multiple locking methods; if you do the order they're declared
# in is important to avoid deadlocks if other MTAs/MUAs are using multiple
# locking methods as well. Some operating systems don't allow using some of
# them simultaneously.
#mbox_read_locks = fcntl
#mbox_write_locks = dotlock fcntl

# lock file after this many seconds.
#mbox_dotlock_change_timeout = 30

# When mbox changes unexpectedly we have to fully read it to find out what
# changed. If the mbox is large this can take a long time. Since the change
# is usually just a newly appended mail, it'd be faster to simply read the
# new mails. If this setting is enabled, Dovecot does this but still safely
# fallbacks to re-reading the whole mbox file whenever something in mbox isn't
# how it's expected to be. The only real downside to this setting is that if
# some other MUA changes message flags, Dovecot doesn't notice it immediately.
# Note that a full sync is done with SELECT, EXAMINE, EXPUNGE and CHECK 
# commands.
#mbox_dirty_syncs = yes

# Like mbox_dirty_syncs, but don't do full syncs even with SELECT, EXAMINE,
# EXPUNGE or CHECK commands. If this is set, mbox_dirty_syncs is ignored.
#mbox_very_dirty_syncs = no

# Delay writing mbox headers until doing a full write sync (EXPUNGE and CHECK

  #   netscape-eoh:
  #     Netscape 4.x breaks if message headers don't end with the empty "end of
  #     headers" line. Normally all messages have this, but setting this
  #     workaround makes sure that Netscape never breaks by adding the line if

  #     commands. Note that RFC says this shouldn't be done.
  #   tb-negative-fetch:

# PAM doesn't provide a way to get uid, gid or home directory. If you don't
# want to use a separate user database (passwd usually), you can use static

# It's possible to export the authentication interface to other programs,
# for example SMTP server which supports talking to Dovecot. Client socket
# handles the actual authentication - you give it a username and password
# and it returns OK or failure. So it's pretty safe to allow anyone access to
# it. Master socket is used to a) query if given client was successfully
# authenticated, b) userdb lookups.

# listener sockets will be created by Dovecot's master process using the
# settings given inside the auth section
#auth default_with_listener {
#  mechanisms = plain
#  passdb = passwd
#  userdb = pam
#  socket listen {
#    master {
#      path = /var/run/dovecot/auth-master
#      #mode = 0600
#      # Default user/group is the one who started dovecot-auth (root)
#      #user = 
#      #group = 
#    }
#    client {
#      path = /var/run/dovecot-auth-client
#      mode = 0660
#    }
#  }

Hi,

existiert /var/run/dovecot?
existiert /var/run/dovecot-login?

kopier mal deine config als Backup, und nimm alles, was du nicht brauchst, raus. Da hat man ja keinen Ã?berblick :)

Achso: /var/run/dovecot-login sollte der Gruppe dovecot angehören.

Nochwas: nimm mal nicht die 1.0-Version.
Ich habe die 0.99.14 und bin sehr zufrieden damit.
