• Multiple IP addresses to one NIC, but advanced IP settings window only shows one?

  - by tridium

  The ipconfig of my Windows Server 2003 server shows that the IP addresses 10.0.0.3, 10.0.0.11, and 10.0.0.12 are assigned to it. However, when I look in the Advanced TCP/IP Settings window for that connection, I only see the IP address of 10.0.0.3 listed there. In the Support tab for the connection, it shows that it's connected through 10.0.0.12, and in the Support Details window, it shows all the previously mentioned IP addresses. Where are these phantom IP addresses being stored and how can I free them up so I don't have any IP conflicts?

• Linux: find thin server running on port 80 and kill it

  - by Andrew

  On my Linux server I ran: sudo thin start -p 80 -d Now I'd like to restart the sever. The trouble is, I can't seem to get the old process to kill it. I tried: netstat -anp But what I see on port 80 is this: Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN - So, it didn't give me a PID to kill... I tried pgrep -l thin but that gave me nothing. Meanwhile pgrep -l ruby gives me like 6 processes running. I don't really understand why multiple ruby threads would be running, or which one I need to kill... How do I kill / restart the thin daemon?

• Trixbox: external SIP with no sound

  - by Leandro Vidal

  I have a trixbox server and every works find except the external SIPs. Inside net all sound goes fine, but if I use a SIP phone outside the net, I can connect, I can receive calls but I there is no sound. I have this text in the sip_nat.conf: nat=yes externhost=xxxxx.dyndns.org localnet=192.168.1.0/255.255.255.0 localhost=192.168.1.210 externrefresh=10 qualify=yes And I have the ports from 5036 to 5082, 4569 and from 10000 to 20000 redirected to 192.168.1.210 on TCP and UDP. What's wrong? Thank you very much in advance

• Two network interfaces and two IP addresses on the same subnet in Linux

  - by Scott Duckworth

  I recently ran into a situation where I needed two IP addresses on the same subnet assigned to one Linux host so that we could run two SSL/TLS sites. My first approach was to use IP aliasing, e.g. using eth0:0, eth0:1, etc, but our network admins have some fairly strict settings in place for security that squashed this idea: They use DHCP snooping and normally don't allow static IP addresses. Static addressing is accomplished by using static DHCP entries, so the same MAC address always gets the same IP assignment. This feature can be disabled per switchport if you ask and you have a reason for it (thankfully I have a good relationship with the network guys and this isn't hard to do). With the DHCP snooping disabled on the switchport, they had to put in a rule on the switch that said MAC address X is allowed to have IP address Y. Unfortunately this had the side effect of also saying that MAC address X is ONLY allowed to have IP address Y. IP aliasing required that MAC address X was assigned two IP addresses, so this didn't work. There may have been a way around these issues on the switch configuration, but in an attempt to preserve good relations with the network admins I tried to find another way. Having two network interfaces seemed like the next logical step. Thankfully this Linux system is a virtual machine, so I was able to easily add a second network interface (without rebooting, I might add - pretty cool). A few keystrokes later I had two network interfaces up and running and both pulled IP addresses from DHCP. But then the problem came in: the network admins could see (on the switch) the ARP entry for both interfaces, but only the first network interface that I brought up would respond to pings or any sort of TCP or UDP traffic. After lots of digging and poking, here's what I came up with. It seems to work, but it also seems to be a lot of work for something that seems like it should be simple. Any alternate ideas out there? Step 1: Enable ARP filtering on all interfaces: # sysctl -w net.ipv4.conf.all.arp_filter=1 # echo "net.ipv4.conf.all.arp_filter = 1" >> /etc/sysctl.conf From the file networking/ip-sysctl.txt in the Linux kernel docs: arp_filter - BOOLEAN 1 - Allows you to have multiple network interfaces on the same subnet, and have the ARPs for each interface be answered based on whether or not the kernel would route a packet from the ARP'd IP out that interface (therefore you must use source based routing for this to work). In other words it allows control of which cards (usually 1) will respond to an arp request. 0 - (default) The kernel can respond to arp requests with addresses from other interfaces. This may seem wrong but it usually makes sense, because it increases the chance of successful communication. IP addresses are owned by the complete host on Linux, not by particular interfaces. Only for more complex setups like load- balancing, does this behaviour cause problems. arp_filter for the interface will be enabled if at least one of conf/{all,interface}/arp_filter is set to TRUE, it will be disabled otherwise Step 2: Implement source-based routing I basically just followed directions from http://lartc.org/howto/lartc.rpdb.multiple-links.html, although that page was written with a different goal in mind (dealing with two ISPs). Assume that the subnet is 10.0.0.0/24, the gateway is 10.0.0.1, the IP address for eth0 is 10.0.0.100, and the IP address for eth1 is 10.0.0.101. Define two new routing tables named eth0 and eth1 in /etc/iproute2/rt_tables: ... top of file omitted ... 1 eth0 2 eth1 Define the routes for these two tables: # ip route add default via 10.0.0.1 table eth0 # ip route add default via 10.0.0.1 table eth1 # ip route add 10.0.0.0/24 dev eth0 src 10.0.0.100 table eth0 # ip route add 10.0.0.0/24 dev eth1 src 10.0.0.101 table eth1 Define the rules for when to use the new routing tables: # ip rule add from 10.0.0.100 table eth0 # ip rule add from 10.0.0.101 table eth1 The main routing table was already taken care of by DHCP (and it's not even clear that its strictly necessary in this case), but it basically equates to this: # ip route add default via 10.0.0.1 dev eth0 # ip route add 130.127.48.0/23 dev eth0 src 10.0.0.100 # ip route add 130.127.48.0/23 dev eth1 src 10.0.0.101 And voila! Everything seems to work just fine. Sending pings to both IP addresses works fine. Sending pings from this system to other systems and forcing the ping to use a specific interface works fine (ping -I eth0 10.0.0.1, ping -I eth1 10.0.0.1). And most importantly, all TCP and UDP traffic to/from either IP address works as expected. So again, my question is: is there a better way to do this? This seems like a lot of work for a seemingly simple problem.

• CentOS listen to everything on the wire

  - by Poni

  I know there's a native command on linux that will output (to stdout) every "event" related to a certain network interface (be it eth0 etc'). Like there's tail -f <file> to listen on file changes.. I just can't find it. I want to see all events, incoming packets, even dropped ones. At lowest level possible. In every protocol (TCP, UDP etc'). I think WireShark is a bit too big for this as I need something very simple just to see the events, it's for testing. What's the command?

• nginx won't respond to monit

  - by Miko

  Although EngineX is running, monit can't seem to figure it out. Here's my monit log: [PDT Apr 13 02:19:19] error : HTTP error: Server returned status 400 [PDT Apr 13 02:19:19] error : 'nginx' failed protocol test [HTTP] at INET[localhost:80] via TCP [PDT Apr 13 02:19:19] info : 'nginx' trying to restart [PDT Apr 13 02:19:19] info : 'nginx' stop: /etc/init.d/nginx [PDT Apr 13 02:19:20] info : 'nginx' start: /etc/init.d/nginx The monitrc file contains the following configuration: if failed port 80 protocol http and request '/ping.txt' # check for response with timeout 20 seconds then restart I can access the file through lynx http://localhost:80/ping.txt without any problems. Why would monit have trouble requesting the file when nginx is running just fine?

• Install SSL certificate for RDP on Windows 2003?

  - by Crashalot

  I need to configure SSL for RDP, and am following the instructions described here: http://thelazyadmin.com/blogs/thelazyadmin/archive/2007/01/26/Configure-RDP-over-SSL-with-SelfSSL.aspx My client's server already has a SSL certificate (.cer file), and I attempted to import it so that Terminal Services would recognize it. The importing instructions I followed are: http://support.microsoft.com/kb/816794#3. Unfortunately, when I click "Edit" from the "RDP-tcp Properties" dialog (for a Terminal Services certificate), no certificate appears. How can I get the certificate to appear here? Thanks!

• Mysql hosting for application backend

  - by churnd

  I've been asked to help set up a way for a volunteer animal rescue organization to use an application to keep track of animals they've rescued. This application already exists, and can use it's own local database or connect to a MySQL database server. Since there are several volunteers spread out over a large region, a database server would be the best way to go. Money is a big problem, obviously. So, I'm looking for a very cheap or hopefully free database server or webhost that allows tcp/ip connections to their database servers. Backups will be handled on our end, so basically I just need the hosted mysql server. I've seen 000webhost.com, x10hosting, and xtreemhost, which all look promising, but they either aren't clear on remote mysql connections, or don't allow it at all. Looking forward to your recommendations! The animals thank you! :)

• Can't log in via SSH to any accounts set to use /bin/bash as a default shell

  - by Gui Ambros

  I'm trying to install bash as the default shell on a ARM Linux running on an embedded device (Synology DS212+ NAS). But there's something really wrong, and I can't figure out what it is. Symptoms: 1) Root has /bin/bash as default shell, and can log in normally via SSH: $ grep root /etc/passwd root:x:0:0:root:/root:/bin/bash $ ssh root@NAS root@NAS's password: Last login: Sun Dec 16 14:06:56 2012 from desktop # 2) joeuser has /bin/bash as default shell, and receives "Permission denied" when trying to log in via SSH: $ grep joeuser /etc/passwd joeuser:x:1029:100:Joe User:/home/joeuser:/bin/bash $ ssh joeuser@localhost joeuser@NAS's password: Last login: Sun Dec 16 14:07:22 2012 from desktop Permission denied, please try again. Connection to localhost closed. 3) changing joeuser's shell back to /bin/sh: $ grep joeuser /etc/passwd joeuser:x:1029:100:Joe User:/home/joeuser:/bin/sh $ ssh joeuser@localhost Last login: Sun Dec 16 15:50:52 2012 from localhost $ To make things even more strange, I can log in as joeuser using /bin/bash using the serial console (!). Also a su - joeuser as root works fine, so the bash binary itself is working fine. In an act of despair, I changed joeuser's uid to 0 on /etc/passwd, but also didn't work, so it doesn't seem to be anything permission related. Seems that bash is doing some extra checking that sshd didn't like, and blocking the connections for non-root users. Maybe some sort of sanity checking - or terminal emulation - that is triggering the SIGCHLD, but only when called via ssh. I already went through every single item on sshd_config, and also put SSHD in debug mode, but didn't find anything strange. Here's my /etc/ssh/sshd_config: LogLevel DEBUG LoginGraceTime 2m PermitRootLogin yes RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys ChallengeResponseAuthentication no UsePAM yes AllowTcpForwarding no ChrootDirectory none Subsystem sftp internal-sftp -f DAEMON -u 000 And here's the output from /usr/syno/sbin/sshd -d, showing the failed attempt of joeuser trying to log in, with /bin/bash as the shell: debug1: Config token is loglevel debug1: Config token is logingracetime debug1: Config token is permitrootlogin debug1: Config token is rsaauthentication debug1: Config token is pubkeyauthentication debug1: Config token is authorizedkeysfile debug1: Config token is challengeresponseauthentication debug1: Config token is usepam debug1: Config token is allowtcpforwarding debug1: Config token is chrootdirectory debug1: Config token is subsystem debug1: HPN Buffer Size: 87380 debug1: sshd version OpenSSH_5.8p1-hpn13v11 debug1: read PEM private key done: type RSA debug1: private host key: #0 type 1 RSA debug1: read PEM private key done: type DSA debug1: private host key: #1 type 2 DSA debug1: read PEM private key done: type ECDSA debug1: private host key: #2 type 3 ECDSA debug1: rexec_argv[0]='/usr/syno/sbin/sshd' debug1: rexec_argv[1]='-d' Set /proc/self/oom_adj from 0 to -17 debug1: Bind to port 22 on ::. debug1: Server TCP RWIN socket size: 87380 debug1: HPN Buffer Size: 87380 Server listening on :: port 22. debug1: Bind to port 22 on 0.0.0.0. debug1: Server TCP RWIN socket size: 87380 debug1: HPN Buffer Size: 87380 Server listening on 0.0.0.0 port 22. debug1: Server will not fork when running in debugging mode. debug1: rexec start in 6 out 6 newsock 6 pipe -1 sock 9 debug1: inetd sockets after dupping: 4, 4 Connection from 127.0.0.1 port 52212 debug1: HPN Disabled: 0, HPN Buffer Size: 87380 debug1: Client protocol version 2.0;

  I am looking for a solution to send SMS/MMS message to mobile device from desktop or browser in LAN environment. As such, it is most probably using TCP/IP protocol to transmit request/response. The server may attach to a GSM device with SIM card attached. An server application would then start accept the request from any LAN client and convey the SMS/MMS to one or more recipients. The server may log all requests for further traffic analysis in later stage. Is there any solution that able to perform what I describe here. Please advice.

  So say I have an arbitrary tcp port 12345 and it's non ssl and I want to put stunnel to secure traffic to it. When stunnel is in front of it does it mean that this port is now tls/ssl only? Or can you still connect to it unencrypted? Basically I want to make sure that this port can only be accessed through ssl/tls and stunel and no other way. Clarification I want to make sure only stunnel port is open. Which is answered in the comments that the unsecured port should be fire-walled but preferably bound to localhost.

• Is there a free-embedded SSH solution ?

  - by ereOn

  Hi, I'm working for an important company which has some severe network policies. I'd like to connect from my work, to my home linux server (mainly because it allows me to monitor my home-automated installation, but that's off-topic) but of course, any ssh connection (tcp port 22) to an external site is blocked. While I understand why this is done (to avoid ssh tunnels I guess), I really need to have some access to my box. (Well, "need" might be exagerated, but that would be nice ;) Do you know any web-based solution that I could install on my home linux server that would give me some pseudo-terminal (served using https) embedded in a web page ? I'm not necessarily looking for something graphical: a simple web-embedded ssh console would do the trick. Or do you guys see any other solution that wouldn't compromise network security ? Thank you very much for your solutions/advices.
