I am running vsftp on one of my systems and when trying to connect to it it errors out with this: vendion@Loki:~> ftp 192.168.1.100 Connected to 192.168.1.100. 500 OOPS: could not bind listening IPv6 socket
I have tried stopping the firewall and even disabling IPv6 nothing changed, any clues as to what is going on?
I am learning network prgramming in linux in c,and try to build a server and in this server I want to bind the listening socket to a paricular Ip address and port.Bind function is showing error,I did not want to use wild card. Here is the code.
#include<stdio.h>
#include<sys/socket.h>
#include<strings.h>
#include<netinet/in.h>

I've registered a top-level domain site.com pointing to my IPv6 address (6to4 tunnel). Everything looks ok, dig command, nslookup command shows requested output, but: I'm not able to connect to mail.site.som on 110 port. I still get an error messaged, that connection has been refused. I've populated the ip6tables with commands to open desired port but with no success. I'm listening on 25, am able to connect to this port, but not to 110.
Command netstat -an | grep "LISTEN " shows that I'm not listening on 110 port, although I'm just added this port to the firewall exceptions. Telnet to ::1/tunneled IPv6 address is successful. Postfix installed, configured properly, ping6 working. Everytime I try to send email from external domain, I'm advised that the mail domain is not pointing to A record.
Anyone knows the difference between a socket and TCP connection for connecting to an external system?

I have installed bind with yum install bind bind-chroot.I am having query timeouts due to no ipv6 connectivity.Is there a way to re-compile and not loose the chroot structure?Or is there another way to disable ipv6 lookups?Example of issue resulting in ipv4 query timeout:

I'm having a little problem here. That, or I'm missing the obvious staring me in the face. I have this file server, called toad. I nuked it's system disk, reorganising the partitions and upgrading to openSUSE 11.3 x64. I installed vsftd with "Yast FTP server", and the config looks OK. I even compared it with that of another machine. But when I try to connect, this is what I get:
user@mainmachine:~> ftp
ftp> open toad
Connected to toad.geuens.org.
500 OOPS: could not bind listening IPv6 socket
I'm prettige sure IPv6 is deactivated. The firewall is disabled on both machines. I've looked this over again and again. Can't find it. It's not the connecting machine, I've tried from another.
I think this goes here, but I'm not sure. I decided that XAMPP had been troublesome enough. MySQL never worked. So I decided to instal the LAMP stack offered by YaST. I went about installing it thinking that it would all work. But it seems that I was wrong. So I try to start mysql, and here's what I get:
Code:
the-matrix:~ # mysql start
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) or

I'm running a native dual-stack (ipv4 & ipv6) dsl connection.So, I've been adding firewall rules, cleaning up unwanted processes, etc to tighten security.I'm left with only 3 processes that are listening to ports. mysql, ipp & ssh.Still not quite sure I need mysql. I run Amarok but without using a database, so I don't actually use sql for anything that I'm aware of.Anyway, my question is;Is it possible to make any any of these processes listen to ipv4 only or ipv6 only? Is there a distinction there at all?
Example- ssh is currently listening to port 22 on both tcp & tcp6. I do all my ssh connections using 'ssh -6', so, Can I make ssh listen to tcp6 only, or ignore tcp ?
I have to wonder how much testing Opensuse has done with yast-dns-server package. After adding zones to the dns server - the system loses the ability to perform name resolutions. I can copy a named.conf file from a system that does work, except everytime the system is restart the named.conf file is rewritten trashing the updates done and again rendering the system to perform name resolutions.
Anyone have suggestions on how to get yast-dns-server from interferring with the configuration file? I tried just uninstalling the package, but then bind doesn't even start up on boot up.
I wrote a code in C to connect to MySQL by using mysql_real_connect function but I recieved error "Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)" (by using mysql_error function).
I also did the following things: in mysql I typed 'SHOW VARIABLES LIKE '%SOCKET%'', it returned /var/lib/mysql/mysql.sock I typed 'mysql_config --socket' in shell, it returned /var/lib/mysql/mysql.sock I modified /etc/my.cnf file
is it possible using a perl script to test for a socket listening on a UDP port on a remote host ?I work in an environment where netcat is not allowed and from time to time I need to see if a UDP port is open on a remote host.

I'm having problems connecting to the mysql database on my system. I first noticed this when I was trying to set up the program anymeal. I subsequently tried using MySQL Administrator (mysql-admin), but had no luck. It gives my the following feedback:
Code:
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Click the 'Ping' button to see if there is a networking problem. I press the ping button, and it seems to connect.

I am currently trying to get a B.A.T.M.A.N mesh network up and running. the thing uses UDP port 4305 for broadcasting to nearby nodes and it seems this port is closed or used by something else.
now i have tried to open this port with commands like
Code:
iptables -A INPUT -p udp --dport 4305 -j ACCEPT
iptables -A OUTPUT -p udp --dport 4305 -j ACCEPT
it still gives me the same error saying the socket cannot connect.any way for me to scan that udp port, see what is blocking it and open the thing up ?
If I open a raw SCTP socket, am I able to bind to a specific port? (I only want to see SCTP packets from a particular IP address AND port.) Or, any raw SCTP socket, regardless of port binding , will get all SCTP packets received by the OS from that IP address? The port doesn't matter and is ignored.
View 1 Replies View RelatedI was logged in as root, made some changes to my users and think I may have inadvertently changed root somehow. Ever since then, my machine runs just fine, I can sudo, Yast, etc without any issues. (Root password is fine) but when I try to log in as root, the system changes the screen display, as if it's going to login, then returns me back to the login prompt without error. If I "ctl+alt+F1", I drop out to the console and can login as root, but cannot startx because the display is already in use.... So, I removed the .X0-lock, but still cannot get the GUI to load. (after running rm /tmp/./X0-lock, I get a fatal error, "can't establish any listening sockets..." "Ctl+Alt+F7" brings me back to the GUI where I am logged in as myself in Gnome) if I login with my user account, everything runs fine and all is well.
View 9 Replies View RelatedI decided to enable dual stack on my home 11.3 machine and play with IPv6. I use ifup to assign static addresses to eth0. FYI here are some things I found:
1. YaST doesn't seem to support associating IPv6 addresses to interfaces, it complains that the address is invalid. However you can edit /etc/sysconfig/network/ifcfg-eth0 manually and specify it like this:
Code:
LABEL_0='V6'
IPADDR_0='FEC::10.1.1.1/64'
SCOPE_0='site'
and when you restart the networking you will see an additional IPv6 address associated with eth0. Fortunately YaST doesn't mangle the entry when you look at it, but you can't edit it.
2. The SCOPE qualifier is documented in /etc/sysconfig/network/ifcfg.template, but seems to have no effect. Site local addresses in IPv6 are supposed to start with FE[CDEF] according to this:
The TCP/IP Guide - IPv6 Special Addresses: Reserved, Private (Link-Local / Site-Local), Unspecified and Loopback
Once bound, you can connect to services using the IPv6 address just like normal. You have to use ping6 instead of ping though.
I added an AAAA record to my nameserver and that seems to work. Whether the client software tries the IPv6 address varies. It depends on whether the software asks for the AAAA record and uses it. It seems my web browsers don't. I'm not surprised, since few people have IPv6 tails from their ISP. I'm going to look and see if there is some browser setting I have to adjust. I also have to figure out a way of making sure that only LAN destinations use IPv6.
does opensuse 11.2 come with IPv6 enabled by default? where in the gnome gui can i access these settings?
Edit-i went into the gnome network manager applet and i cant find any IPv6 settings for any of my used connections-ethernet, wireless and VPN connections all seem to only IPv4. Can anyone else confirm that opensuse 11.2 uses only IPv4 on its network connections?
I am running suse11.3 32 bit, and have installed squid3.
As far as I can tell it's not been compiled with ipv6 support.
Or have I missed some option in some file somewhere?
I am trying to create a socket to listen for a bootp response so I am using a PF_PACKET socket so that I get the response based on my mac. My problem is that I don't want to hear all traffic (as I do now) so would like to use a specific port number and bind to it.

ERROR 2002 (HY0000): can't connect to local MySQL server through socket
I have installed MySQL over yum on fedora.
but the path and file /var/lib/mysql/mysql.sock does not exist on my system?
I've tried /etc/init.d/mysql start, and it actually starts, or at least, it doesn't error out. But when I do pgrep mysql I get nothing, and when I try to login with mysql -p as root, I get
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
None of my other logins work, either, but since pgrep mysql didn't work, it's clear that MySQL just isn't running. I tried uninstalling and reinstalling mysql-server via apt-get, but I get the same thing. The logs in /var/log/syslog show this:
