Thunderbird 17.0.4 connection refused , other clients working ? password OK

Hi,
A bit odd, I have started getting my Tbird email connection refused yet can access email fine from iPhone/iPad and from alpine on my laptop using the same account details
I deleted and recreated my account in Tbird, but same thing. I have very carefully re-entered my password same thing.
I'm using Tbird 17.0.4 on Ubuntu. Its consistent with my password being wrong, yet it isn't.
I'm a bit unsure, are some additional restrictions in place on Tbird versions. Mine is pretty much up to date with Ubuntu 12.04 LTS

Hi,
We have no restrictions on T'Bird versions on Beehiveonline. There may be some on stbeehive but you would have to redirect your query to one of the internal forums on http://myforums.oracle.com/jive3/category.jspa?categoryID=735

  • SFTP, FTP, HTTP Connection Refused through clients

    I have an off-site storage server that I've been using for a while. All of a sudden the past couple of weeks while trying to connect through Transmit or Cyberduck all I get is "connection refused" whenever I attempt to connect through SFTP, FTP, or HTTP. The IT guys for the server state it's fine but when I try to ping my ports on my mac my port 22 and 21 aren't visible.
    What in the heck is going on?

    Here is the log output for:
    ssh -v -v -v [email protected]
    What does ssh_connect: needpriv 0 mean?

  • Hardware - ipw2200 giving me connection refused, usb wifi works fine?

    Hi
    Im having a funny problem with the network at work, connecting with the ipw2200 module and card doesnt seem to work.
    netcfg says done, i can ping the ap and the dns server. Aswell as sniff the network. Her`s the kicker, wget tells me connection refused.
    When i get something like that I automaticly tought i was a firewall or a wrong config on my part, but that cant be.
    If i connect with a usb wifidongle, zd1211, give that the same device name as the ipw2200 have when thats loaded everything works great. Note that this only happens at work with the ipw2200 wifi card. How can this be?  I find this very strange.
    Thanks for any help, chers

    At work ping gives me 100% loss, regardless of which device I use to connect with.
    Thats why i started using wget for testing of the connection

  • 127.0.0.1 Connection refused

    For some reason, I am unable to send or receive messages. The senders and receivers get no error messages, but the messages get stuck in the mail queue with the error "delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]: Connection refused"
    It has worked perfectly in the past. I recently began using DNS service (I wasn't previously), but now it won't work with the DNS on or off.
    Correction: When I turn DNS off, I get this error: The error that the other server returned was: 550 550 #5.1.0 Address rejected [email protected] (state 14).
    Message was edited by: vidgpersonrsw

    The 'delivery temporarily suspended' message is coming from postfix trying to pass the message through some kind of filter process that isn't running.
    For example, the anti-virus scanner runs in this manner - messages come into the server, postfix passes the message to the scanner via a custom port on 127.0.0.1 and the scanner passes it back to postfix.
    You should check that all your mail components are working correctly.

  • Connection Refused Error In Connection Client

    Hello Geeks
    I am runnig a RMI application in which runs on internet , i have setup RMI server on a host server and it is running there.
    Now, when i try to call client using ip address of the Host , i am getting Connection Refused error.
    Example :
    Registry registry=LocateRegistry.getRegistry("70.33.246.110");
    System.out.println("Above connectMe");
    String  serverName = "rmi://70.33.246.110:2786/connectUser";
    connectMe stub=(connectMe)Naming.lookup(serverName);
    System.out.println("Below connectMe");
    boolean log=stub.login(username,password,1);
    System.out.println("Below login");Here "connectuser" is name i have given in server to which client lookups.I am getting -> Above connectMe and Below connectMe
    but then i am getting connection refused error.
    Please Help Me Out.....ASAp
    Edited by: Hardik.Mishra on Oct 3, 2009 5:46 PM

    Registry registry=LocateRegistry.getRegistry("70.33.246.110");There's no point to doing that ...
    System.out.println("Above connectMe");
    String serverName = "rmi://70.33.246.110:2786/connectUser";
    connectMe stub=(connectMe)Naming.lookup(serverName);... if you're doing that. The getRegistry() doesn't do a network operation, it just constructs a stub to that Registry locally. Only by using it would you find out whether it meant anything: and you're not using it.
    I am getting -> Above connectMe and Below connectMe
    but then i am getting connection refused error.See item A.1 on the RMI Frequently Asked Questions list in the Javadoc.

  • Cisco Jabber Client for Windows 9.7 Can't Connect to Other IPSec VPN Clients Over Clustered ASAs

    Environment:
    2 x ASA 5540s (at two different data centers) configured as a VPN Load Balancing Cluster
    Both ASAs are at version 8.4(5)6
    IPSec VPN Client version: 5.0.07.440 (64-bit)
    Jabber for Windows v9.7.0 build 18474
    Issue:
      If I am an IPSec VPN user…
       I can use Jabber to another IPSec VPN user that is connected to the same ASA appliance.
       I can’t use Jabber to another IPSec VPN user that is connected to the different ASA appliance that I am connected to.
    In the hub-and-spoke design, where the VPN ASA is a hub, and the VPN client is a spoke; if you have two hubs clustered together, how does one spoke communicate with another spoke on the other hub in the cluster? (How to allow hairpinning to the other ASA)

    Portu,
    Thanks for your quick reply.
    Unfortunately, I do not have access to the ASA logs nor would I be permitted to turn on the debug settings asked for above.  I might be able to get the logs but it will take awhile and I suspect they wouldn't be helpful as this ASA supports thousands of clients, therefore, separating out my connection attempts from other clients would be difficult.
    I can, though, do whatever you want on the Linux router.  Looking over the firewall logs at the time of this problem, I don't see anything that looks suspicious such as dropped packets destined for the Windows client.
    As I said in my original post, I'm not a networking expert - by any means - but I am willing to try anything to resolve this.  (But I might need a bit of handholding if I need to set up a  wireshark andor tcpdump.)
    Thanks again.

    We have had this "PRX5" problem with Exchange 2013 since the RTM version.  We recently applied CU3, and it did not correct the problem.  We have seen this problem on every Exchange 2013 we manage.  They are all installations where all roles
    are installed on the same Windows server, and in our case, they are all Windows virtual machines using Windows 2012 Hyper-V.
    We have tried all the "this fixed it for me" solutions regarding DNS, network cards, host file entries and so forth.  None of those "solutions" made any difference whatsoever.  The occurrence of the temporary error PRX5 seems totally random. 
    About 2 out of 20 incoming mail test by Microsoft Connectivity Analyzer fail with this PRX5 error.
    Most people don't ever notice the issue because remote mail servers retry the connection later.  However, telephone voice mail systems that forward voice message files to email, or other such applications such as your scanner, often don't retry and
    simply fail.  Our phone system actually disables all further attempts to send voice mail to a particular user if the PRX5 error is returned when the email is sent by the phone system.
    Is Microsoft totally oblivious to this problem?
    PRX5 is a serious issue that needs an Exchange team resolution, or at least an acknowledgement that the problem actually does exist and has negative consequences for proper mail flow.

  • Problems with SSH: Connection Refused

    Greetings fellow Arch users,
    I have hit a bit of a snag that I could really use some extra help getting around. I've tried everything I can think of (and everything that Google thought might work) and I have my back rather against a wall, so I thought I'd come here to see if anyone can offer some advice.
    To make a long story short, I am a college student and am attempting to set up an ssh server on a desktop at my house so I can access it remotely from the college. I have the computer set up and the server running, however I am having difficulty making connections to it from my laptop. I know that the server is running, because I can log into it both from the server itself (sshing into local host) and from my laptop when I use the internal IP address.
    The server is on a static IP address within the network(192.168.0.75), and my router is configured to forward TCP port 1500 to it (I'm using 1500 as the port for my ssh server). However, when I attempt to log into the ssh server using my network's external IP address, the connection is refused. I used nmap to scan my network and found that, even though the proper ports are forwarded to the proper place as far as my Router's configuration interface is concerned, port 1500 is not listed as one of the open TCP ports. I also, to test it, temporarily disabled the firewalls on both the server and the client. That didn't help. The command that I am running is:
    ssh -p 1500 douglas@[external ip address
    As I am really not sure what is causing this problem, I don't know what information to provide. So here is everything that my inexperienced mind sees as likely being important. If you need anything more, let me know and I will do my best to provide it.
    Here is the sshd_config file from my server.

    Thank you guys ahead of time. Getting this server operational is hardly critical, it is just a side project of mine, but I would really like to see it working.

    Okay, so I finally have the opportunity to try and log in from a remote network. And. . .  it doesn't work. Which is just my luck because I now need to wait an entire week, at least, before I can touch the server again. Anyway, running ssh with the maximum verbosity I get this output:
    douglas ~ $ ssh -vvv -p 2000 address
    OpenSSH_6.3, OpenSSL 1.0.1e 11 Feb 2013
    debug1: Reading configuration data /home/douglas/.ssh/config
    debug1: Reading configuration data /etc/ssh/ssh_config
    debug2: ssh_connect: needpriv 0
    debug1: Connecting to address [address] port 2000.
    debug1: connect to address address port 2000: Connection timed out
    ssh: connect to host address port 2000: Connection timed out
    It takes a minute or two for the command to finish with the connection timeout, as one would expect. And yes, I am reasonably sure that the address that I am using is my home network's external IP. It is dynamic, but I checked it before I left which was just over an hour ago. I guess that it may have changed. I'll know that for sure in the morning, when my server sends me an automatic email with the network's current address. In the meantime I am operating under the assumption that the address I am using is correct. What else could be the problem?

  • Lion Server postfix mail not being delivered to mailboxes. "SMTP restriction `reject_invalid_helo_hostname' after `permit' is ignored" and "connect to private/policy: Connection refused" errors.

    All, Im stumped. In fact I have been on the phone with Apple Support and this has been escalated to the top engineers, as I think its got them too..
    Anyway, here is my problem..
    I'm running an Mac Mini with OS X 10.7.4 Server. I have had mail running on it for 2 months or so, without any issues. The mail was actually migrated from 10.6 in March, and It actually went smoothly. I have 3 domains which all recieve mail and they all work (or did up until 2 weeks ago)..
    So the story is this.. I can send mail from my domains, without issue.  imap and dovecot must be working.. cause all the stored mail, can be read with the mail IMAP client.. I can even transfer mail messages from one mailbox to another with Mail client. Sending mail is a breeze, it still works and the recipients still recieve their mail. But I noticed I wasnt getting any mail at all from those mailboxes... no mail, no spam, nothing.. which is unusal. I fired up Server admin and checked out the SMTP log, and this is what it showed for every email recieved: (xxxxxx is just me hiding sensitive info)

    Ok, now what is odd, is these rejected messages are not even appearing in the mail queue in Server Admin. I have no idea why there are not being delivered
    Ive checked my postfix main.cf file and master.cf files they both look ok.. Ive even replaced them with the main.cf.defualt.10.7 and master.cf.default.10.7 files and to no avail... same problem..
    So in summary
    I can send mail out
    IMAP is working on the client end (thus dovecot is) exsisting stored emails can be accessed, read, moved unread etc..
    mail is coming into the sever, but its being rejected. there is NO rejection email sent back to the sender.
    mail is recieved by postfix, but cyrus isnt doing anything with it.. I have no idea where it goes...
    Could anyone shed light on this...

    # The myhostname parameter specifies the internet hostname of this
    # mail system. The default is to use the fully-qualified domain name
    # from gethostname(). $myhostname is used as a default value for many
    # other configuration parameters.
    #myhostname = host.domain.tld
    #myhostname = virtual.domain.tld
    # The mydomain parameter specifies the local internet domain name.
    # The default is to use $myhostname minus the first component.
    # $mydomain is used as a default value for many other configuration
    # parameters.
    #mydomain = domain.tld
    # SENDING MAIL
    # The myorigin parameter specifies the domain that locally-posted
    # mail appears to come from. The default is to append $myhostname,
    # which is fine for small sites.  If you run a domain with multiple
    # machines, you should (1) change this to $mydomain and (2) set up
    # a domain-wide alias database that aliases each user to
    # [email protected].
    # For the sake of consistency between sender and recipient addresses,
    # myorigin also specifies the default domain name that is appended
    # to recipient addresses that have no @domain part.
    #myorigin = $myhostname
    #myorigin = $mydomain
    # RECEIVING MAIL
    # The inet_interfaces parameter specifies the network interface
    # addresses that this mail system receives mail on.  By default,
    # the software claims all active interfaces on the machine. The
    # parameter also controls delivery of mail to user@[ip.address].
    # See also the proxy_interfaces parameter, for network addresses that
    # are forwarded to us via a proxy or network address translator.
    # Note: you need to stop/start Postfix when this parameter changes.
    #inet_interfaces = all
    #inet_interfaces = $myhostname
    #inet_interfaces = $myhostname, localhost
    # The proxy_interfaces parameter specifies the network interface
    # addresses that this mail system receives mail on by way of a
    # proxy or network address translation unit. This setting extends
    # the address list specified with the inet_interfaces parameter.
    # You must specify your proxy/NAT addresses when your system is a
    # backup MX host for other domains, otherwise mail delivery loops
    # will happen when the primary MX host is down.
    #proxy_interfaces =
    #proxy_interfaces = 1.2.3.4
    # The mydestination parameter specifies the list of domains that this
    # machine considers itself the final destination for.
    # These domains are routed to the delivery agent specified with the
    # local_transport parameter setting. By default, that is the UNIX
    # compatible delivery agent that lookups all recipients in /etc/passwd
    # and /etc/aliases or their equivalent.
    # The default is $myhostname + localhost.$mydomain.  On a mail domain
    # gateway, you should also include $mydomain.
    # Do not specify the names of virtual domains - those domains are
    # specified elsewhere (see VIRTUAL_README).
    # Do not specify the names of domains that this machine is backup MX
    # host for. Specify those names via the relay_domains settings for
    # the SMTP server, or use permit_mx_backup if you are lazy (see
    # STANDARD_CONFIGURATION_README).
    # The local machine is always the final destination for mail addressed
    # to user@[the.net.work.address] of an interface that the mail system
    # receives mail on (see the inet_interfaces parameter).
    # Specify a list of host or domain names, /file/name or type:table
    # patterns, separated by commas and/or whitespace. A /file/name
    # pattern is replaced by its contents; a type:table is matched when
    # a name matches a lookup key (the right-hand side is ignored).
    # Continue long lines by starting the next line with whitespace.
    # See also below, section "REJECTING MAIL FOR UNKNOWN LOCAL USERS".
    #mydestination = $myhostname, localhost.$mydomain, localhost
    #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
    #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain,
    #       mail.$mydomain, www.$mydomain, ftp.$mydomain
    # REJECTING MAIL FOR UNKNOWN LOCAL USERS
    # The local_recipient_maps parameter specifies optional lookup tables
    # with all names or addresses of users that are local with respect
    # to $mydestination, $inet_interfaces or $proxy_interfaces.
    # If this parameter is defined, then the SMTP server will reject
    # mail for unknown local users. This parameter is defined by default.
    # To turn off local recipient checking in the SMTP server, specify
    # local_recipient_maps = (i.e. empty).
    # The default setting assumes that you use the default Postfix local
    # delivery agent for local delivery. You need to update the
    # local_recipient_maps setting if:
    # - You define $mydestination domain recipients in files other than
    #   /etc/passwd, /etc/aliases, or the $virtual_alias_maps files.
    #   For example, you define $mydestination domain recipients in   
    #   the $virtual_mailbox_maps files.
    # - You redefine the local delivery agent in master.cf.
    # - You redefine the "local_transport" setting in main.cf.
    # - You use the "luser_relay", "mailbox_transport", or "fallback_transport"
    #   feature of the Postfix local delivery agent (see local(8)).
    # Details are described in the LOCAL_RECIPIENT_README file.
    # Beware: if the Postfix SMTP server runs chrooted, you probably have
    # to access the passwd file via the proxymap service, in order to
    # overcome chroot restrictions. The alternative, having a copy of
    # the system passwd file in the chroot jail is just not practical.
    # The right-hand side of the lookup tables is conveniently ignored.
    # In the left-hand side, specify a bare username, an @domain.tld
    # wild-card, or specify a [email protected] address.
    #local_recipient_maps = unix:passwd.byname $alias_maps
    #local_recipient_maps = proxy:unix:passwd.byname $alias_maps
    #local_recipient_maps =
    # The unknown_local_recipient_reject_code specifies the SMTP server
    # response code when a recipient domain matches $mydestination or
    # ${proxy,inet}_interfaces, while $local_recipient_maps is non-empty
    # and the recipient address or address local-part is not found.
    # The default setting is 550 (reject mail) but it is safer to start
    # with 450 (try again later) until you are certain that your
    # local_recipient_maps settings are OK.
    unknown_local_recipient_reject_code = 550
    # TRUST AND RELAY CONTROL
    # The mynetworks parameter specifies the list of "trusted" SMTP
    # clients that have more privileges than "strangers".
    # In particular, "trusted" SMTP clients are allowed to relay mail
    # through Postfix.  See the smtpd_recipient_restrictions parameter
    # in postconf(5).
    # You can specify the list of "trusted" network addresses by hand
    # or you can let Postfix do it for you (which is the default).
    # By default (mynetworks_style = subnet), Postfix "trusts" SMTP
    # clients in the same IP subnetworks as the local machine.
    # On Linux, this does works correctly only with interfaces specified
    # with the "ifconfig" command.
    # Specify "mynetworks_style = class" when Postfix should "trust" SMTP
    # clients in the same IP class A/B/C networks as the local machine.
    # Don't do this with a dialup site - it would cause Postfix to "trust"
    # your entire provider's network.  Instead, specify an explicit
    # mynetworks list by hand, as described below.
    # Specify "mynetworks_style = host" when Postfix should "trust"
    # only the local machine.
    #mynetworks_style = class
    #mynetworks_style = subnet
    #mynetworks_style = host
    # Alternatively, you can specify the mynetworks list by hand, in
    # which case Postfix ignores the mynetworks_style setting.
    # Specify an explicit list of network/netmask patterns, where the
    # mask specifies the number of bits in the network part of a host
    # address.
    # You can also specify the absolute pathname of a pattern file instead
    # of listing the patterns here. Specify type:table for table-based lookups
    # (the value on the table right-hand side is not used).
    #mynetworks = 168.100.189.0/28, 127.0.0.0/8
    #mynetworks = $config_directory/mynetworks
    #mynetworks = hash:/etc/postfix/network_table
    # The relay_domains parameter restricts what destinations this system will
    # relay mail to.  See the smtpd_recipient_restrictions description in
    # postconf(5) for detailed information.
    # By default, Postfix relays mail
    # - from "trusted" clients (IP address matches $mynetworks) to any destination,
    # - from "untrusted" clients to destinations that match $relay_domains or
    #   subdomains thereof, except addresses with sender-specified routing.
    # The default relay_domains value is $mydestination.
    # In addition to the above, the Postfix SMTP server by default accepts mail
    # that Postfix is final destination for:
    # - destinations that match $inet_interfaces or $proxy_interfaces,
    # - destinations that match $mydestination
    # - destinations that match $virtual_alias_domains,
    # - destinations that match $virtual_mailbox_domains.
    # These destinations do not need to be listed in $relay_domains.
    # Specify a list of hosts or domains, /file/name patterns or type:name
    # lookup tables, separated by commas and/or whitespace.  Continue
    # long lines by starting the next line with whitespace. A file name
    # is replaced by its contents; a type:name table is matched when a
    # (parent) domain appears as lookup key.
    # NOTE: Postfix will not automatically forward mail for domains that
    # list this system as their primary or backup MX host. See the
    # permit_mx_backup restriction description in postconf(5).
    #relay_domains = $mydestination
    # INTERNET OR INTRANET
    # The relayhost parameter specifies the default host to send mail to
    # when no entry is matched in the optional transport(5) table. When
    # no relayhost is given, mail is routed directly to the destination.
    # On an intranet, specify the organizational domain name. If your
    # internal DNS uses no MX records, specify the name of the intranet
    # gateway host instead.
    # In the case of SMTP, specify a domain, host, host:port, [host]:port,
    # [address] or [address]:port; the form [host] turns off MX lookups.
    # If you're connected via UUCP, see also the default_transport parameter.

    # REJECTING UNKNOWN RELAY USERS
    # The relay_recipient_maps parameter specifies optional lookup tables
    # with all addresses in the domains that match $relay_domains.
    # If this parameter is defined, then the SMTP server will reject

    #relay_recipient_maps = hash:/etc/postfix/relay_recipients
    # INPUT RATE CONTROL
    # The in_flow_delay configuration parameter implements mail input
    # flow control. This feature is turned on by default, although it
    # still needs further development (it's disabled on SCO UNIX due
    # to an SCO bug).
    # A Postfix process will pause for $in_flow_delay seconds before
    # accepting a new message, when the message arrival rate exceeds the
    # message delivery rate. With the default 100 SMTP server process
    # limit, this limits the mail inflow to 100 messages a second more
    # than the number of messages delivered per second.
    # Specify 0 to disable the feature. Valid delays are 0..10.
    #in_flow_delay = 1s
    # ADDRESS REWRITING

    # ALIAS DATABASE
    # The alias_maps parameter specifies the list of alias databases used

    # On systems with NIS, the default is to search the local alias
    # database, then the NIS alias database. See aliases(5) for syntax
    # details.
    # If you change the alias database, run "postalias /etc/aliases" (or
    # wherever your system stores the mail alias file), or simply run
    # "newaliases" to build the necessary DBM or DB file.
    # It will take a minute or so before changes become visible.  Use
    # "postfix reload" to eliminate the delay.
    #alias_maps = dbm:/etc/aliases
    #alias_maps = hash:/etc/aliases
    #alias_maps = hash:/etc/aliases, nis:mail.aliases
    #alias_maps = netinfo:/aliases
    # The alias_database parameter specifies the alias database(s) that
    # are built with "newaliases" or "sendmail -bi".  This is a separate
    # configuration parameter, because alias_maps (see above) may specify
    # tables that are not necessarily all under control by Postfix.
    #alias_database = dbm:/etc/aliases
    #alias_database = dbm:/etc/mail/aliases
    #alias_database = hash:/etc/aliases
    #alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases
    # ADDRESS EXTENSIONS (e.g., user+foo)
    # The recipient_delimiter parameter specifies the separator between
    # user names and address extensions (user+foo). See canonical(5),
    # local(8), relocated(5) and virtual(5

    Ok 1st one. The warning restriction message relates to this line in main.cf:
    smtpd_helo_restrictions = permit_sasl_authenticated  permit_mynetworks  check_helo_access hash:/etc/postfix/helo_access  reject_non_fqdn_hostname  reject_invalid_hostname  permit reject_invalid_helo_hostname
    The last reject occurs after the single word "permit" and is ignored.
    However, that's not the problem.
    I'm not exactly sure what's happening, but this might be a clue.
    It would appear that either postfix is not being able to create the socket for private/policy or it's somehow created with the wrong permissions.  You might need to ramp up the debug level to get a better idea.
    You could check if it's being created by "netstat -a | grep private/policy" in terminal.
    My guess is that it's not being created because there is no setup statement in your master.cf file, but I don't understand why postfix would be looking for it if it isn't set up.  Private/policy I think relates to grey listing.  Maybe gives you a hint.

    It's called potential deadlock. The emulator blocks your app 'cause any connection and commandAction needs its own thread. So I suggest use a new thread with this http connection then your program will be run successful.

    I have been struggling with this problem a couple of days now so I really hope someone can help me. I am trying to get rmi to work in a NAT environment.
