  • Android openvpn + zeroconf browser sending mdns query packets over eth0 instead of tap0 interface on wifi

    - by Mrunal
    On an android device, I am connecting to a remote network using openvpn for performing service discovery. WORKING CASE: After the device is camped on 3g/4g and after connecting to remote network by openvpn, when the zeroconf browser is launched, I can see the mdns query packets being send through the tap0 interface resulting into rendering of services on the browser. From the tcpdump captured on the device, I can see that the mdns query packets are send to tap0 interface. tap0 ip: 192.168.11.200 Route table information: Destination Gateway Genmask Flags Metric Ref Use Iface 76.26.112.234 10.179.240.1 255.255.255.255 UGH 0 0 0 pdpbr1 10.179.240.1 * 255.255.255.255 UH 0 0 0 pdpbr1 32.1.72.136 * 255.255.255.255 UH 0 0 0 pdpbr0 10.179.240.0 * 255.255.255.0 U 0 0 0 pdpbr1 192.168.11.0 * 255.255.255.0 U 0 0 0 tap0 default 192.168.11.1 0.0.0.0 UG 0 0 0 tap0 NOT WORKING CASE: However, after switching on the wifi and connecting it to remote network, when the zeroconf browser is launched, instead of sending the mdns query packets to tap0 interface; these packets are being send to eth0 interface due to which we cannot see the services. From the tcpdump captured on the device, I can see that mdns query packets are send to eth0 interface. tap0 ip: 192.168.11.200 eth0 ip: 192.168.43.230 route table information: Destination Gateway Genmask Flags Metric Ref Use Iface 76.26.112.234 192.168.43.1 255.255.255.255 UGH 0 0 0 eth0 32.1.72.136 * 255.255.255.255 UH 0 0 0 pdpbr0 192.168.11.0 * 255.255.255.0 U 0 0 0 tap0 192.168.43.0 * 255.255.255.0 U 0 0 0 eth0 default 192.168.11.1 0.0.0.0 UG 0 0 0 tap0 In the above case, even though there is a default route for tap0, all the multicast packets are being routed through eth0. How is this possible? Has anyone observed a similar problem and it would be really helpful if you can help us to discover services through zeroconf browser after the device is connected to remote network via openvpn through wifi. Thank You Very much, Mrunal

  • Can't ping through default gateway

    - by Andrew G.H.
    I have the following configuration: Routing table on M3 is: Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 eth1 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.3.0 0.0.0.0 255.255.255.192 U 0 0 0 eth0 Routing table on M1 is: Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 So basically M3's gateway is M1, and M1's gateway is M2's wireless internet interface. If I ping 8.8.8.8 from M1, everything is ok, replies are received. Pinging from M1 to M3 and viceversa is also possible. I have configured M1 as gateway trafic forwarder using firestarter package and stopped firewall with it. iptables policies are ACCEPT for everything. Problem: I have tried ping-ing ip 8.8.8.8 from M3 but without success. What could be the source of this problem?

  • Anyone know a good mind mapper that works with a scheduler?

    - by GLycan
    TL;DR: Mind mapping tasks to be processed into a schedule based on task metadata. I have all sorts of ideas about what to invest resources (mainly time) in, but when I actually have time to do something I useually end up browsing reddit for not knowing what do to, and the frequancy with which I forget deadlines scares me. I'd love to bring order and structure into my mind, and always know what to do next. So, I want a mind mapping app, where I'd give each branch (types and subtypes of things I want to do) a importance score (if there were two branches, and one had 60 while the other 40, they would respectivily get 60% and 40% of the parent's importance, with the root being 100) and a how soon that branch should be revised/updated (an hobby I want to try out might be checked, say, once a week, while a school subject should be checked once a day) and give each leaf (something I want/need to do) how much time it takes, deadline (if any), and optionally an absolute importance, reoccurrence (guitar practice might repeat once a week), and prerequisites (reading something requires that book (although that could be brought somewhere), coding requires a box, jogging requires being outside) and maybe some other flags, like if it's enjoyable or not. It should either be packaged or working with a schedular app, to which I'd say, look, my day works this way (completely busy from 8 to 9:15, then 15 minutes of being inside with nothing, ..., two hours with box and possibility to go outside, etc), saying that such-and-such pattern is school and happens ever weekday except such-and-such days. The output should be of the form of a schedule, fit for printing or, when I finally get an android, mobile viewing, that schedules tasks with regards to availability of resources and importance (importance being derived from the leaf-task's parent branches), and the set of flags (all work and no play makes me a dull boy). One of these tasks should be reviewing anything that should be updated on that day, including future day layouts (e.g, if the time slots of future days have changed. This should be done every day.) Does anyone know some collection of preferably open-source (or free, or pirateable) tools, or better yet a single one, that accomplishes this task? I know python pretty well, and should be able to write any necessary glue.

  • Why can't I bind to 127.0.0.1 on Mac OS X?

    - by Noah Lavine
    Hello, I'm trying to set up a simple web server on Mac OS X, and I keep getting an error when I run bind. Here's what I'm running (this transcript uses GNU Guile, but just as a convenient interface to posix). (define addr (inet-aton "127.0.0.1")) ; get internal representation of 127.0.0.1 (define sockaddr (make-socket-address AF_INET addr 8080)) ; make a struct sockaddr (define sock (socket PF_INET SOCK_STREAM 0)) ; make a socket (bind sock sockaddr) ; bind the socket to the address That gives me the error In procedure bind: can't assign requested address. So I tried it again allowing any address. (define anyaddr (make-socket-address AF_INET INADDR_ANY 8080)) ; allow any address (bind sock anyaddr) And that works fine. But it's weird, because ifconfig lo0 says lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 inet 127.0.0.1 netmask 0xff000000 So the loopback device is assigned to 127.0.0.1. So my question is, why can't I bind to that address? Thanks. Update: the output of route get 127.0.0.1 is route to: localhost destination: localhost interface: lo0 flags: <UP,HOST,DONE,LOCAL> recvpipe sendpipe ssthresh rtt,msec rttvar hopcount mtu expire 49152 49152 0 0 0 0 16384 0

  • Extremely high mysqld CPU usage with no active queries

    - by RadarNyan
    I have a VPS running Ubuntu 12.04 LTS with LEMP stack, followed the guide from Linode Library (since I'm using a Linode) to setup, and everything worked fine until now. I don't know what's wrong, but my CPU usage just goes up since a week ago. Today things getting really bad - I got 74% CPU usage so I went check and found that mysqld taking too much CPU usage (somewhere around 30% ~ 80%) So I did some Google Search, tried disable InnoDB, restart mysql, reset ntp / system clock (Isn't this bug supposed to happen more than a year ago?!) and reboot my VPS, nothing helped. Even with mysql processlist empty, I still get mysqld CPU usage very high. I don't know what I missed and have totally no idea, any advice would be appreciated. Thanks in advance. Update: I got these from running "strace mysqld" write(2, "InnoDB: Unable to lock ./ibdata1"..., 44) = 44 write(2, "InnoDB: Check that you do not al"..., 115) = 115 select(0, NULL, NULL, NULL, {1, 0}^[[A^[[A) = 0 (Timeout) fcntl64(3, F_SETLK64, {type=F_WRLCK, whence=SEEK_SET, start=0, len=0}, 0xbfa496f8) = -1 EAGAIN (Resource temporarily unavailable) hum... I did tried to disable InnoDB and it didn't fix this problem. Any idea? Update2: # ps -e | grep mysqld 13099 ? 00:00:20 mysqld then use "strace -p 13099", the following lines appears repeatedly: fcntl64(12, F_GETFL) = 0x2 (flags O_RDWR) fcntl64(12, F_SETFL, O_RDWR|O_NONBLOCK) = 0 accept(12, {sa_family=AF_FILE, NULL}, [2]) = 14 fcntl64(12, F_SETFL, O_RDWR) = 0 getsockname(14, {sa_family=AF_FILE, path="/var/run/mysqld/mysqld.sock"}, [30]) = 0 fcntl64(14, F_SETFL, O_RDONLY) = 0 fcntl64(14, F_GETFL) = 0x2 (flags O_RDWR) setsockopt(14, SOL_SOCKET, SO_RCVTIMEO, "\36\0\0\0\0\0\0\0", 8) = 0 setsockopt(14, SOL_SOCKET, SO_SNDTIMEO, "<\0\0\0\0\0\0\0", 8) = 0 fcntl64(14, F_SETFL, O_RDWR|O_NONBLOCK) = 0 setsockopt(14, SOL_IP, IP_TOS, [8], 4) = -1 EOPNOTSUPP (Operation not supported) futex(0xb786a584, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0xb786a580, {FUTEX_OP_SET, 0, FUTEX_OP_CMP_GT, 1}) = 1 futex(0xb7869998, FUTEX_WAKE_PRIVATE, 1) = 1 poll([{fd=10, events=POLLIN}, {fd=12, events=POLLIN}], 2, -1) = 1 ([{fd=12, revents=POLLIN}]) er... now I totally don't get it x_x help

Sure it will block some legit packets but if it means keeping the box up it works till the attack goes away but I would like to LEARN how to FIND other common things in a packet to block with IPTables

  • OARC's DNSSEC validating resolvers validate all my records but A records

    - by demize
    I have DNS set up with powerdns. It serves my DNS pretty well, and it AXFRs to other slaves. The slaves haven't yet updated to the most recent records, but that doesn't affect the validation, it would appear. Any record I can think of (AAAA, MX, TXT, even the CNAME for www) validates -- except for A records: dig @149.20.64.20 +dnssec www.demize95.com CNAME returns ;; flags: qr rd ra ad; QUERY: 1, ANSWER: 2, AUTHORITY: 5, ADDITIONAL: 7 while dig @149.20.64.20 +dnssec demize95.com A returns ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 5, ADDITIONAL: 7. The same happens with any other A record I have. I set up DNSSEC with pdnssec, and it does work for all the other records, but it's never validated for my A records. What's the problem here? Also, a side-note: I have to use ISC's DLV to create the chain of trust, since my domain registrar doesn't yet support sending the DS records to the com zone.

  • Remote access to phpmyadmin from computer belongs to same LAN

    - by Charles
    OK... I solved it. It is because I have not configured the httpd.conf to allow the centos listen port 80 and 8080. Listen 80 Listen 8080 I have setup the myphpadmin on my CentOS 6.4 recently. I can access and login to the myphpadmin on my localhost. However, when I type http://[hostipaddr]/phpmyadmin on my other computer in the same LAN with the CentOS, the browser simply cannot access the page. Below are some of the current configuration. Anyone can help please......? config.inc.php $i++; /* Authentication type */ $cfg['Servers'][$i]['auth_type'] = 'http'; /* Server parameters */ $cfg['Servers'][$i]['host'] = 'localhost'; $cfg['Servers'][$i]['connect_type'] = 'tcp'; $cfg['Servers'][$i]['compress'] = false; /* Select mysql if your server does not have mysqli */ $cfg['Servers'][$i]['extension'] = 'mysql'; $cfg['Servers'][$i]['AllowNoPassword'] = false; phpmyadmin.conf <Directory /var/www/html/phpmyadmin/> order allow,deny allow from all </Directory> Furthermore, I can access the webpage that stored in the CentOS from my other computer without problems. After using wireshark and tcpdump, I found that the server (the Cent OS) keep resetting the connection.

  • Server resolve issues not consistent

    - by bobthemac
    I am having some weird issues with my web server. It has a public ip address and is set-up on an openVZ virtual machine. Accessing in to the site works fine every time but when trying to access out from the server I can't always connect out. Sometimes I can connect out and resolve addresses, sometimes I can't. The issue is visible in both ssh when trying to do a wget command on Google; sometimes it works and I get the index.html page and sometimes I get nothing. The issue is more visible in wordpress where you can't view themes but after a few presses of the try again button you can then view them. I have searched google and found nothing about this issue. Does anyone here have any ideas what could be causing this strange behaviour? Ports 80 and 2222 are open for web and ssh.

  • moving files and directories between two machine, via a third, preserving permissions and usernames

    - by Jarmund
    The situation is as follows: Machine A has a file repository accessible via rsync Machine B needs the above mentioned files with all permissions and ownerships intact (including groups etc) Machine C has access to both A and B, but has a completely different set of users. Normally, i would just rsync everything over, directly between A and B, but due to severely limited bandwidth at the moment, i need something different, as rsync times out after building the list of the 430 files (49Mb uncompressed... can be compressed down to ~7Mb). What i've tried so far: rsync everything over from A to C, tar it, copy the tarball over, and then untar it, however, this messes up the ownership and/or the permissions. To rsync it from A to C, i run this command: rsync --numeric-ids --password-file=/root/rsync_pwd_file -oaPvu rsync://[email protected]/portal_2/ ./portal_2/ ...and from the looks of things, they do end up on C with the correct ownerships/permissions/flags/everything (not 100% sure, though.. are there any more switches i can throw in there? did i miss something?) copying the tarball over is simple enough (slow as a one-legged turtle due to the bandwidth, but it checksums out alright) What i'm unsure of is the flags and switches for creating and extracting the tarball, so could someone please provide the full commands for creating a tarball from /root/portal_2 on machine C (with everything intact) and extracting the tarball into /var/ex/portal_2 on machine B? ? Also, are there any other approaches worth mentioning that could allow me to perform this? I have root access to A and C, whereas i only have rsync access to B. PS: I'm running rsync v2.6.9 on machine B, and unfortunately i do not have the oportunity to upgrade to v3

  • Allow outgoing connections for DNS

    - by Jimmy
    I'm new to IPtables, but I am trying to setup a secure server to host a website and allow SSH. This is what I have so far: #!/bin/sh i=/sbin/iptables # Flush all rules $i -F $i -X # Setup default filter policy $i -P INPUT DROP $i -P OUTPUT DROP $i -P FORWARD DROP # Respond to ping requests $i -A INPUT -p icmp --icmp-type any -j ACCEPT # Force SYN checks $i -A INPUT -p tcp ! --syn -m state --state NEW -j DROP # Drop all fragments $i -A INPUT -f -j DROP # Drop XMAS packets $i -A INPUT -p tcp --tcp-flags ALL ALL -j DROP # Drop NULL packets $i -A INPUT -p tcp --tcp-flags ALL NONE -j DROP # Stateful inspection $i -A INPUT -m state --state NEW -p tcp --dport 22 -j ACCEPT # Allow established connections $i -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # Allow unlimited traffic on loopback $i -A INPUT -i lo -j ACCEPT $i -A OUTPUT -o lo -j ACCEPT # Open nginx $i -A INPUT -p tcp --dport 443 -j ACCEPT $i -A INPUT -p tcp --dport 80 -j ACCEPT # Open SSH $i -A INPUT -p tcp --dport 22 -j ACCEPT However I've locked down my outgoing connections and it means I can't resolve any DNS. How do I allow that? Also, any other feedback is appreciated. James

  • "SASL authentication failed" with mutt and Gmail, why?

    - by hhh
    I am confused by this, I have installed a lot of new pkgs and followed some tutorials after googling but I keep getting this kind of SASL -err. I am not sure whether the mistake is in some Gmail settings or should I check some settings in Ubuntu? I thought this tutorial here would have solved this problem (i am simply trying to set up local mail reading with mutt, using gmail) but I cannot see the instructed things with telnet: "250-STARTTLS 250-AUTH PLAIN LOGIN" so that is why it is not working. $cat .muttrc set imap_user = "[email protected]" set imap_pass = "pass" #set smtp_url = "smtp://[email protected]:465/" set smtp_url = "smtp://[email protected]:587/" set smtp_pass = "pass" set from = "[email protected]" set realname = "name" set folder = "imaps://imap.gmail.com:993" set spoolfile = "+INBOX" set postponed="+[Gmail]/Drafts" set move = no

  • Thunderbird 16.0.1 filling disk space

    - by Kris
    I'm on Ubuntu 12.04 with Thunderbird 16.0.1 and Kernel 3.6.0-030600rc4-generic. I used Thunderbird for quite a while and never had any problems with it. But now it seems to fill up my disk space very fast: watch -n 1 df -h . so Ubuntu started giving out warnings. First I removed some files but not much later it had filled up around 600 MB. It eats around 50 MB/min while I just download 10 emails or so via IMAP. This behaviour is new and seems to be some kind of bug. I don't want to delete my old mails, so what else could I do?

  • problems using evolution Contacts with an DavMail LDAP Proxy for an Exchange server

    - by WegDamit
    i have an davmail proxy setup for accessing an Exchnage 200x server. eMail works fine in Thunderbird and Evolution (IMAP...) LDAP Contacts/Address Book works in TB, but not on Evolution. It seems that Evolution does not try the given credentials. The entered LDAP Auth is never send to the DaVMail Proxy. anonymous access to ou=people forbidden davmail.ui.tray.DavGatewayTray.displayMessage(DavGatewayTray.java:96) It the same conf for TB and in Evolution so i looks like an issue with Evolution to me. Does it take some different cponfig than TB for the credentials? Anybody got this conf workin an can give me some hints? Thanks, WegDamit

  • Looking for a simple to use email server that can be programmatically (preferably remotely) used

    - by sr2222
    I've been poking around the internet for much of the day, but I can't seem to find a good server to fit my needs. What I need is a simple to use and deploy (pref open source) lightweight email server that I can create users on programmaticly that has IMAP or POP support. I'd prefer something with an existing service interface, but if I have to write a REST API on top of an easy to use API, that's acceptable. The purpose of this tool will be to allow a test automation framework to create new email accounts and retrieve email sent to those addresses. I need text, html, and possibly attachment support as well. Perhaps it's my noobishness, but I can't really suss out the details from the documentation on the servers available out there to figure out which fit my needs.

  • How to Export Email "Sent" Folder?

    - by user249493
    A client had her web site and email hosted at "company A". She was switching to "company B" but didn't want to lose her email. I set up a Gmail account, POPed into her webmail account, and pulled the entire inbox into Gmail (for later transfer to her new host). But I forgot about the "sent" folder. Although the hosting plan is still up and running, she changed her domain record to point to the new host. So I can't access the old webmail account via POP or IMAP because the email address needed for authentication now resolves to the new host. Is there any way I can get the contents of the sent folder without having to do a "forward" one message at a time (there are hundreds)?

  • Connect to a Microsoft Exchange 5.5 server using Evolution

    - by Mike
    I am trying to set up Evolution to connect to my company's Exchange server, but I got this error after entering the request OWA URL and credentials: The Exchange server is not compatible with Exchange Connector. The server is running Exchange 5.5. Exchange Connector supports Microsoft Exchange 2000 and 2003 only. I read that I can use Thunderbird or IMAP if it's enabled, but that I'd lose calendar and contacts sync. I'd rather not do that. Is there a workaround for this so that I can get roughly the same functionality I'd get using Outlook for Windows?
