• Convert from port numbers to protocol names ?

  - by Berkay

  i'm simply using tshark -r botnet.pcap -T fields -E separator=';' -e ip.src -e tcp.srcport -e ip.dst -e tcp.dstport '(tcp.flags.syn == 1 and tcp.flags.ack == 0)' to see the all initiated "legal TCP" connections. However, i need the destination port number conversion to "http" "netbios" etc. i'm not using -n option, but still i get: 128.3.45.128;62259;208.233.189.150;80 This is what i'm trying to get: 128.3.45.128;62259;208.233.189.150;http or 128.3.45.128;62259;208.233.189.150;80;http is better option for me. any idea from tshark users? or any other tool suggestions?

• Is there any way to send Outlook meeting requests from a non-default calendar?

  - by rbeier

  Hi, We have a user with two Outlook accounts. [email protected] is of type Exchange; [email protected] is of type IMAP/SMTP. Both are actually on our Exchange server; but since an Outlook profile can only have one Exchange account, the second one is set up as IMAP. The user would like to send a meeting request from her xyz.com account, so the "from" address appears as [email protected]. Unfortunately that doesn't work. If she creates the meeting in her xyz.com calendar, the meeting request still goes out through her Exchange account, [email protected]. The meeting request "compose message" window has an Account dropdown below the Send button, but this has no effect. Before she sends the invitation, a warning appears: "Responses to this meeting request will not be tallied because this meeting is not in your main Calendar folder. Is this OK?" Is there any workaround for this? We're using Outlook 2007 and Exchange 2003 SP2. Thanks, Richard

• Ubuntu box static routing problem

  - by Rafael

  Hello, I'm trying to configure a ubuntu server to be a router. This is my interface configuration (eth2 connects to my WAN, eth0 to my LAN): auto eth2 iface eth2 inet static address 192.168.0.249 netmask 255.255.255.0 gateway 192.168.0.1 broadcast 192.168.0.255 auto eth0 iface eth0 inet static address 192.168.100.1 netmask 255.255.255.0 This is the router information: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 0.0.0.0 192.168.0.1 0.0.0.0 UG 100 0 0 eth2 And this is dhcp configuration: subnet 192.168.100.0 netmask 255.255.255.0 { range 192.168.100.101 192.168.100.254; option domain-name-servers 201.70.86.133; option routers 192.168.100.1; authoritative; } I'm then connecting a mac os x by cable on eth0.

• Postfix not working

  - by user1488723

  A while ago I installed the postfix mail server on my ubuntu 10.04 VPS. At the time it was working good but now it's just stopped working. I was trying to enable SASL authentification and somewhere it must have went really wrong. I've studied the postfix main.cf and done everything in an orderly fashion to ensure that it is nothing wrong. I also have Dovecot installed and configured dovecot.conf to run with Postfix. If I try to do telnet localhost 25 while logged in on the server I just get: Connection closed by foreign host. If I try to do telnet mail.example.com 25 "from the outside" I get: telnet: Unable to connect to remote host: No route to host And when I check the server log after the failed attempts I see this: Jun 28 15:49:31 msv postfix/smtpd[11839]: initializing the server-side TLS engine Jun 28 15:49:31 msv postfix/smtpd[11839]: connect from localhost.localdomain[127.0.0.1] Jun 28 15:49:31 msv postfix/smtpd[11839]: warning: SASL: Connect to /var/spool/postfix/private/auth failed: Connection refused Jun 28 15:49:31 msv postfix/smtpd[11839]: fatal: no SASL authentication mechanisms Jun 28 15:49:32 msv postfix/master[11598]: warning: process /usr/lib/postfix/smtpd pid 11839 exit status 1 Jun 28 15:49:32 msv postfix/master[11598]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling main.cf file looks like this: smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no append_dot_mydomain = no delay_warning_time = 4h myhostname = mail.example.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases mydomain = example.com myorigin = $mydomain mydestination = $mydomain relayhost = mynetworks = 127.0.0.1 mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all smtpd_use_tls = yes smtpd_tls_loglevel = 2 smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_sasl_auth_enable = yes smtpd_client_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination smtpd_sender_restrictions = permit_sasl_authenticated, permit_mynetworks smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination broken_sasl_auth_clients = yes smtpd_sasl_type = dovecot smtpd_sasl_path = /var/spool/postfix/private/auth smtpd_sasl_security_options = noanonymous Dovecot.conf file looks like this: protocols = imap imaps disable_plaintext_auth = no log_timestamp = "%b %d %H:%M:%S " ssl = yes ssl_cert_file = /etc/postfix/ssl/smtpd.crt ssl_key_file = /etc/postfix/ssl/smtpd.key mail_location = maildir:~/mail mail_access_groups = mail auth_username_chars = abcdefghijklmnopqrstuvwxyz protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep } auth default { mechanisms = plain login passdb pam { } userdb passwd { } socket listen { client { path = /var/spool/postfix/private/auth user = postfix group = postfix mode = 0660 } } }

• Sending emails with Thunderbird + Postfix + Zarafa does not work

  - by Sven Jung

  I installed zarafa on my vserver and use as MTA postfix. The webaccess works fine, I can revceive and send emails, also receiving mails with thunderbird (IMAP ssl/tls) works. But there is a problem, sending emails with thunderbird. I established an account in thunderbird with imap ssl/tls connection which works finde, and a starttls smtp connection on port 25 for the outgoing mail server. If I try to send an email with thunderbird I get an error: 5.7.1 Relay access denied this is my mail.log Sep 7 16:10:07 postfix/smtpd[6153]: connect from p4FE06C0A.dip.t-dialin.net[79.224.110.10] Sep 7 16:10:08 postfix/smtpd[6153]: NOQUEUE: reject: RCPT from p4FE06C0A.dip.t-dialin.net[79.224.110.10]: 554 5.7.1 <[email protected]>: Relay access denie$ Sep 7 16:10:10 postfix/smtpd[6153]: disconnect from p4FE06C0A.dip.t-dialin.net[79.224.110.10] and this my /etc/postfix/main.conf # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache virtual_mailbox_domains = firstdomain.de, seconddomain.de virtual_mailbox_maps = hash:/etc/postfix/virtual virtual_alias_maps = hash:/etc/postfix/virtual virtual_transport = lmtp:127.0.0.1:2003 myhostname = mail.firstdomain.de alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all inet_protocols = ipv4 I don't know what to do, because actually sending mails to internal and external addresses works with the webaccess.

• Where are the Microsoft downloaded app compat updates stored?

  - by Ian Boyd

  Where are the Microsoft application compatibility update settings stored on a Windows XP, Windows Vista, and Windows 7 computer? Microsoft periodically release application compatibility updates (e.g. KB929427), where they list the shims that should be applied to a program in order to workaround known bugs in the software. Where are these app compat flags stored, and how can i see what shims are being applied? i have a feeling that a recent app compat update included a flag to force a particular piece of software, that we use, to require administrator. Because the task is scheduled to run nightly, and the running user does not have administrative privelages, the task is failing to start. The application is requiring to be elevated. It has the UAC shield overlay. The application has no RT_MANIFEST resource, and the compatibility option Run this program as administrator is disabled (per-user and all users). So all that's left is some secret global setting. i know user-specified compat flags are stored in: HKEY_LOCAL_MACHINE \SOFTWARE \Microsoft \Windows NT \CurrentVersion \AppCompatFlags \Layers

• Create access point (uap0) on debian 7(arm) - not found?

  - by ethrbunny

  I'm working with a fanless PC that has an ARM chipset, 2 eth plugs and a wifi card (among other things). If I install debian 6 on it all three network interfaces are available at boot time. Today I tried to install debian 7 and had numerous errors indicating that the wireless card isn't supported. uap0: error fetching interface information: Device not found SIOCSIFADDR: No such device uap0: ERROR while getting interface flags: No such device uap0: ERROR while getting interface flags: No such device No such device ERR:UAPHOSTCMD is not supported by uap0 ERR:Command sending failed! No such device ERR:UAPHOSTCMD is not supported by uap0 ERR:Command sending failed! I've tried comparing the kernel module list to the working system but there are too many other differences to make something obvious enough (to me) stand out. How would I get started debugging this problem?

• How to search with Spotlight more effectively

  - by Chris Adams

  I'm used to using various flags to modify the results of Google searches, to only show results from a particular site, or only certain kinds of files. For example you can restrict Spotlight searches to only look for pdf files like this example, when I'm looking for a pdf cheatsheet for using YUI's grid system css framework on my computer. YUI grid kind:pdf I'd be amazed if Apple's Spotlight didn't have loads of other handy flags to fine tune a search in the same way - what tricks do you use, or where do you look to find more tips to improve your Spotlight-fu?

• Google Contacts/Calendars + Address Book + iCal: built-in sync (problems) or Exchange sync?

  - by jtbandes

  (I've looked at a few other questions related to this, but I've only found old questions with people saying that they're having problems, or anticipating Snow Leopard fixing them; no recent updates.) I'm looking to sync my Google Contacts & Calendars, and Gmail, with my Mac & iPhone. The iPhone I have currently set up thus: IMAP for Mail Exchange (Google Sync) for Contacts & Calendars The Mac: Address Book: built-in sync iCal: CalDAV, configured as a Google account I haven't been syncing Gmail to Apple Mail, because I was having weird IMAP glitches every so often that just got to annoying. Will Exchange / Google Sync work for this at all? Any suggestions there? Here are the other problems I'm having. Address Book only syncs certain fields (for example, Birthdays don't sync at all). I believe this is a list of the information that's synced. Address Book's "Synchronize with Google" checkbox doesn't stay checked when I quit Address Book. I think iCal is working fine, for the most part. Any suggestions on how to improve this setup? Why doesn't Address Book / Google Contacts sync stay enabled? Could I use Exchange for it like I am on the iPhone? Will that sync all the fields, including Birthdays, etc.? Thanks in advance!

• Why are default spamassassin rules not being applied to emails we generate?

  - by Chance

  My company uses a standalone spam-assassin install to test marketing emails, however, mail originating from us does not seem to run the full gamut of test. For example, Spam assassin has a default rule that flags messages that contain the phrase Dear [Something], and it properly flags spam that I feed it.It does not, however, apply that same rule to in house email I send it. Is it possible that spam assassin has white-listed us somehow, perhaps because the mail originates in the same domain as the server or receiver? I believe most of the recent spamassassin questions have been mine, so thanks for bearing with me as I figure this out! Chance EDIT Details on our SA setup: We are piping the emails into the CL with spamc -R < test_email.eml Identical results testing as root or a user, no user_prefs file

• Using Cygwin in Windows 8, chmod 600 does not work as expected?

  - by Castaa

  I'm trying to change the the permissions to my key file key.pem in Cygwin 1.7.11. It has the permissions flags: -rw-rw---- chmod -c 600 key.pem Reports: mode of 'key.pem' changed from 0660 (rw-rw----) to 0600 (rw-------) However: ls -l key.pem still reports key.pem's permission flags are still: -rw-rw---- This reason why I'm asking is that ssh is complaining: Permissions 0660 for 'key.pem' are too open. when I try to ssh into my Amazon EC2 instance. Is this an issue with Cygwin & Windows 8 NTFS or am I missing something?

• Emails not sending from outlook / OWA - Not even hitting the mail queue in exchange

  - by webnoob

  We are having an issue this morning where we can receive external emails but cannot send internal or external ones from Outlook or OWA. If I use: Send-MailMessage –From <[email protected]> –To <[email protected]> –Subject “Test #01”-Body “Just a test message.” –SMTPServer <Server-Name> –Credential <domain\user> the email is sent correctly which makes me think there is a connection issue with OWA and Outlook. However, outlook is reporting as Connected with exchange. I have checked the message tracking in exchange tools and emails sent via outlook and OWA do not appear. Nothing has changed on the server on the weekend so I don't really know where to start debugging this issue. We are using Windows SBS 2011. We only have one send connector which isn't using Smart Hosts and is set to use DNS MX records. Use external DNS is not checked and I can ping google.com etc so doesn't appear to be a DNS issue (plus the email sends from the console anyway). EDIT It appears that users using IMAP can send emails correctly, its only ones that rely on the normal exchange connection type that don't work. EDIT Emails from IMAP are hitting the email queue's where as emails from the normal exchange accounts aren't. EDIT It seems that some of the emails we tried to send yesterday sent at about 1am but now it won't work again..

• Ubuntu cannot access internet, LAN is fine

  - by Kevin Southworth

  I have an Ubuntu 8.04 LTS server that is directly connected to our Comcast Business Gateway modem and I have configured it with 1 of our 5 allotted Static IPs. My other machines on our LAN can connect to this server (via ssh, web, ping, etc.) but I cannot access this server from outside our network, and this machine cannot get out to the internet either (ping google.com fails with unknown host). Here is my /etc/networking/interfaces file: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 173.162.54.19 netmask 255.255.255.248 broadcast 173.162.54.23 gateway 173.162.54.22 and my /etc/resolv.conf: nameserver 68.87.77.130 nameserver 68.87.72.130 output from sudo route -n: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 173.162.54.16 0.0.0.0 255.255.255.248 U 0 0 0 eth0 0.0.0.0 173.162.54.22 0.0.0.0 UG 100 0 0 eth0 I have a Windows 2008 machine with an almost identical Static IP, static DNS setup and it works correctly, can access it within the LAN and also from public internet, the Windows machine and the Ubuntu machine are both directly connected to the Comcast Business Gateway.

• OS X server VPN local ip

  - by gbrandt

  Hi all, I have 10.6.2 server on the internet. I want to vpn into it to get access. I start VPN and it gives me an address in the range I have set 192.168.2.100-192.168.2.105. However the server itself does not have a local ip of 192.168.2.x so I cannot ping it or ssh into it or anything. The machine VPNing gets an ifconfig entry that looks like this: ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280 inet 192.168.2.100 --> 70.72.xxx.xxx netmask 0xffffff00 Where I think it should get: ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280 inet 192.168.2.100 --> 192.168.2.1 netmask 0xffffff00 I can't find anywhere to set the local vpn IP address. And I can't find a pptpd.conf file either. Any help is appreciated.

• Change Outlook's default calendar to iCloud (meeting requests end up in wrong calendar)

  - by flohei

  Following scenario: I've got a main computer (Windows 7, Office 2010) which is being used to manage contacts, meetings, etc. using Outlook. Now I've added an iPad and an iPhone to sync using iCloud. I moved all appointments and contacts from the old PST file to the iCloud file. All the data syncs nicely. The email account I'm using in Outlook is an IMAP account which opens up another data file which brings us to a total of three data files in Outlook's side bar. The problem: When one of our clients sends us meeting requests via email they show up in the IMAP's inbox. When we open them up they automatically get added to Outlook's default calendar (the one in the original PST). Is there any chance not to add them to that calendar but the iCloud one? Basically we could completely get rid of the original PST since we don't use it at all anymore but the settings do not allow me to remove this PST file and set the iCloud one as default. Thanks!

• DNS no longer works after server reboot

  - by Burning the Codeigniter

  Strangely enough, when I reboot my Ubuntu 12.04 server, the DNS no longer works, which makes the domain unavailable to access to my site. Normally the DNS should be working after a reboot, but this doesn't happen anymore. I use nginx to serve content, but nginx is already configured to work with my domains. What are the typical practises must I do after a reboot and how can I solve this issue I experience? I already have BIND, networking and resolvconf to boot when the server boots up. ; <<>> DiG 9.8.1-P1 <<>> mysite.com ;; global options: +cmd ;; connection timed out; no servers could be reached This is my output with dig $ttl 38400 mysite.com.

• Recommendations for good Unix MTA / groupware solutions? [closed]

  - by Jez

  Possible Duplicate: Exchange server replacement that runs on Linux I'm setting up a Debian server, and one of the things I need on it is an MTA. I don't want to use something like Exim or Postfix because I want something that ties in SMTP, POP3, and IMAP all in one (a la Microsoft Exchange). Most MTAs also seem to be hellishly difficult to configure. Try and read the Exim documentation; you could do a university degree on it (I'm not kidding). When you can get an HTTP server like Cherokee which is easy to configure and has a nice web interface, do MTAs or groupware solutions need to be that hard? I'm aware that some people think "the Unix way" is to have lots of different interacting pieces of software (like maybe an SMTP MTA, POP3 service, webmail service, and overarching manager to tie them all together), but I think this is a situation where that just makes things a lot harder to deal with and one large software suite fits in much more nicely. So, I'm looking for good open source software suites that will run on Debian that: Combine (at least) SMTP, POP3, and IMAP Are easy(ish) to configure Have a nice configuration web interface or GUI Are not defunct projects I don't mind if it's groupware and offers calendaring too, but I would only be using the e-mail functionality for now. Another nice-to-have would be built-in webmail (if we're combining a bunch of functionality, why not?) Note however that I do NOT need Outlook support. I am not really looking for an "Exchange replacement drop-in". The suites I've found so far that seem to match the above criteria (and have appropriate licenses) are Citadel, Kolab, and Zimbra. I'd appreciate anyone who has experience with any of these giving me the pros and cons of them, such as how easy they are to configure and what their performance is like. I'd also appreciate any other suggestions for solutions that fulfil my criteria that I may have missed out.

• Dovecot starting and running, but not listening on any port

  - by Dženis Macanovic

  Among others things I'm in charge of a Debian GNU/Linux (Wheezy) DomU for the mail services of the company i work for. Yesterday one HDD that was used for this particular server has died. After installing Debian again, Dovecot decided to no longer listen on any ports (checked with netstat -l). Other services (like Postfix and MySQL) work without problems. dovecot -n: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-3-amd64 x86_64 Debian wheezy/sid ext3 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%n mail_uid = vmail namespace inbox { inbox = yes location = prefix = } pass db { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0666 user = vmail } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </etc/ssl/private/mail.crt ssl_key = </etc/ssl/private/mail.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_max_userip_connections = 25 } UID 150 is vmail (I double checked file permissions). I didn't install Dovecot from source, but via apt from the official Debian US mirror. There are no messages concerning Dovecot in /var/log/syslog except for: Oct 21 06:36:29 server dovecot: master: Dovecot v2.1.7 starting up (core dumps disabled) Any ideas?

• Is there a learnable filter in Thunderbird for non-spam messages (as in Opera Mail)?

  - by Debilski

  One feature I like very much about Opera Mail is that you can have learnable filters for any purpose. So not only can you filter spam messages but also messages that your friends sent you or info mails from web platforms without having to enter each and every mail address you want to filter. It actually works quite satisfying and you can combine it with string filtering, too. It does a few mistakes in the beginning but then improves quickly after you have removed some of the false positives. However, there are a couple of drawbacks with the Opera Mail module. The filters are only ‘virtual’. So, with IMAP there is no easy way of mirroring the filtered structure back on the server and when I’m using webmail I’ll see the whole unfiltered mess in the inbox folder. Opera’s not using the OS X address book — and neither does it use ldap (which is not too important for me at the moment). So, I’m not specifically looking for a Thunderbird solution here, a way to fix things in Opera or Apple Mail should do as well. Or some other E-Mail program I don’t even know about yet. (So, to be clear, I’d like to have: OS X Address Book integration, Learnable filters for any type of filtering, Ability to push filtered folder structure to the IMAP server) But I thought like, if it is possible then most probably there would be an add-on for Thunderbird available. Any ideas?

• Email Proxy Ideas

  - by jtnire

  Hi Everyone, I wish to host some managed email servers for some customers. Each customer will have their own email server which will be an all-in-one virtual machine running postfix, dovecot and some webmail suite. Even though each customer will have their own server, I do not wish to give each email server it's own public facing IP. I wish to avail the use of proxy servers so all customers use the same public IP. As for the "smtp-in" from the public internet, this isn't a problem as I can set up many mx servers (using postfix) which will store-and-forward the mail to the correct server (using transport maps). As for the IMAP access from the customer, I was thinking of using perdition which is an IMAP proxy - I believe that this will suit my needs. I am confused however on what to use for the "smtp-out" proxy. The customers will have to authenticate with their receptive email server, however they will have to go via a proxy of some sort as they won't have direct access to their server instance. It probably can't be a store-and-forward proxy either. Does anyone have any idea on what I could use here? Many Thanks
