• Port knocking via SSH tunnels

  - by j0ker

  I have a server running in my university's internal network. There is only one SSH daemon running which is secured by port knocking with knockd. Works fine if I try to connect from within the internal network. But since the server has no external IP, I have to tunnel into the internal network every time I want to access the server from outside. And since tunneling only works for a single port I cannot do the port knocking as easily as from an internal client. In fact, I don't get it to work at all. What I'm trying is opening tunnels for all the different ports that have to be knocked. Then I send TCP-SYN packets into the tunnels. But that doesn't work even for a single port. If I establish the tunnel on the first port in the knock sequence and send a packet through it, it doesn't reach the server. There is no entry in the log file of knockd, while there should be something like 123.45.67.89: openSSH: Stage 1 (as shown with internal knocks). So I guess, the problem doesn't exist within my knocking script but is a more general one. Are there any known problems with what I'm trying to do? Is it even possible or am I missing something? Thanks in advance!

• Using Computer name in URL causes issues when connecting to Web Services

  - by AWinters

  The set of applications I work on all access the same 8 or so web services that we have. These services and applications all reside on the same box and all use the computer name when trying to connect to the web service. For Example: If I have a web service called MapDataService and I have an application that accesses it, it would access it by the URL: http://COMPUTERNAME/MapDataService/MapDataService.asmx. This works in most of the applications that access the web service. However, we have several applications that, when using the computer name in the URL, will not get data returned from the service (actually a 503 is returned). In order to get it to work, the IP address of the system needs to be used in place of the COMPUTERNAME. This strikes me as very odd considering, as I mentioned before, all applications and services are on the same box and most other applications usr the COMPUTERNAME with no issues. Can someone give me some insight as to what could be causing this? We have no access to IIS logs and what logs we did get (this is on a customer site) are not very useful.

• SQL Server Subscriber Migration

  - by SuperCoolMoss

  We're currently have one way transaction replication from a SQL Server 2005 OLTP publisher/distrbituor to two subscribers (one SQL 2005 and the other SQL2008 R2). Replication security is via the SQL Agents' domain service account (the same account is used on all boxes). The SQL2008R2 subscriber is used for BI purposes and hosts a database that has a subset of the Production publisher database tables, with different security and indexes. We need to migrate this BI subscriber to a newer box with more performant hardware. The plan is as follows: Stop replicating to the BI box (continue replicating to the other subscriber). Backup all databases on the BI box (including system databases). Restore all databases (including master in single user mode) to the new BI box (this has SQL Server 2008R2 already installed). Take the old BI box off the network and shut it down. Rename and Re-IP the new BI box to be the same as the old box. Switch replication back on. Are there any flaws in this approach?

• What Windows service binds a NIC to the network?

  - by Bigbio2002

  I have a server that takes several minutes for the NIC to bind itself to the network upon startup (it has a statically-configured IP). This causes DNS/WINS/Intersite Messaging to fail to start, since they're dependent on a network connection. While I'm still attempting to find a root cause to this issue (I've done firmware updates, checked for any odd drivers/services, no luck so far), but in the meantime, I want to adjust the load order of services to ensure that the NIC binds first before these services attempt to start. The only question is, which service is it? The server is running Server 2008 R2 and only has one NIC installed. (On a side note, there are two other small but odd problems occuring with the server. The server had the issue described in KB2298620, which I've fixed. The other problem occurs in Windows Server Backup. No events appear in the upper portion of the window, despite the fact that backups are running in the background. Whenever I attempt to modify the backup schedule, it gives me the error "Not enough storage is available to process this command" and appears to fail, when, in fact, it actually succeeds. These may be separate issues, but something tells me that some of these might share a common root cause.)

• Connection failed between Windows Servers

  - by Kerby82

  I'm setting up an infrastructure based on Windows Server 2012. The firewall is turned off and I can't access the Domain controller to check for the group policy. I'm experiencing some connection problem between servers. All the servers are running a site on the TCP Port 80 and I check with netstat that the web server is binding on every Ip of the servers. If i try to telnet from the server itself on the port 80 it works (using DNS name) if I try same telnet from another machine I get connection failed. The DNS works, the ping is successfull, the servers are on the same subnet, the firewall is turned off (even though windows advanced firewall says that some settings can be managed by the System Administrator, i guess group policy). I don't know how to troubleshoot further. Do you have any idea? Is that possible that the FW looks turned off but there are some group policy blocking the connections? (I also check group policy-Administrative Template-Network Connections- Windows FW everything is not configured) I need some hint on how to keep troubleshooting such a problem.

• Can Internet data be used by malware when PC off?

  - by Val

  I have noticed over the last month that my off peak data has been used at a rate of approx 350MB per hour - this has meant that I have gone over my quota and slowed down by my ISP to 256k. There is no one in the house using it (2am-8am is my ISPs off peak hours) at that time. My PC and other wireless devices (ipad and iphone) are turned off. I have changed the wireless password on my modem 3 times and it is now 30 digits long. So I don't think someone else is using my wireless access between 2-8am. It has been suggested by my ISP that I may have malware/spyware on my computer. Sorry for my ignorance, but can malware still run if the PC is off? I did look at my modem's log and followed an IP address to a service called Amazon Simple server Storage. Could this company possibly be the culprit? I am not too tech savvy, so any assistance appreciated. I have run a barrage of spyware cleaning software eg malware bytes; spy bot etc.... Cheers Val

• Using Active Directory through a Firewall

  - by Adam Brand

  I had kind of a weird setup today where I wanted to enable Windows Firewall on a Windows 2003 R2 SP2 computer that would act as an Active Directory Domain Controller. I didn't see one resource on the Internet that listed what would be required to do this, so I thought I'd list them here and see if anyone has anything to add/sees something that isn't necessary. Ports to Open with "subnet" scope: 42 | TCP | WINS (if you use it) 53 | TCP | DNS 53 | UDP | DNS 88 | TCP | Kerberos 88 | UDP | Kerberos 123 | UDP | NTP 135 | TCP | RPC 135 | UDP | RPC 137 | UDP | NetBIOS 138 | UDP | NetBIOS 139 | TCP | NetBIOS 389 | TCP | LDAP 389 | UDP | LDAP 445 | TCP | SMB 445 | UDP | SMB 636 | TCP | LDAPS 3268 | TCP | GC LDAP 3269 | TCP | GC LDAP Ports to Open with "Any" Scope (for DHCP) 67 | UDP | DHCP 2535 | UDP | DHCP ALSO You need to restrict RPC to use fixed ports instead of everything 1024. For that, you need to add two registry keys: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters Registry value: TCP/IP Port Value type: REG_DWORD Value data: <-- pick a port like 1600 and put it here HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters Registry value: DCTcpipPort Value type: REG_DWORD Value data: <-- pick another port like 1650 and put it here ...don't forget to add entries in the firewall to allow those in (TCP, Subnet scope). After doing all that, I was able to add a client computer to the AD domain (behind Windows Firewall) and log in successfully.

• When modern computers boot, what initial setup of RAM do they execute, and how does it exactly work?

  - by user272840

  I know the title reeks of confusion, and some of you might assume I am just wondering about how the computer boots in general, but I'm not. But I'll sort this out for you people now: 1.Onboard firmware is how mostly all modern computer devices work, whether or not with EFI/UEFI(even without "onboard firmware", older computers still employed bank switching, or similar methods with snap-in firmware, cartridges, etc.) 2.On startup there is no "programs" running in the traditional sense yet, i.e. no kernel, OS, user-applications; all of the instructions, especially the very first instruction, is specified by the Instruction Pointer, I am guessing. How is the IP/PC/etc. set to first point to an address for a BIOS/firmware/etc. instruction, and how do the BIOS instructions map themself out in memory prior to startup? 3.Aside from MMIO, BIOS uses certain RAM addresses to have instructions. The big ? comes in when I ask this ... how does BIOS do this? Conclusion: I am assuming that with the very first instruction there is an initial hardware setup for BIOS prior to complete OS bootup. What I want to know is if it's hardware engineered to always work this way, if there's another step in this bootup method I am missing, a gap of information I am unaware of, or how this all works from the very first instruction, and the RAM data itself.

• Wake on Lan Remote not waking PC while the PC does receive the packet.

  - by Nycrea

  Over the last couple of weeks, I have been trying to set up WOL from a remote location. When I use my laptop to wake the machine locally, it works just fine. (for some reason, when I try to wake from my phone with an app called "WOL wake on lan" it does not work locally either, but I'll get to that later) Anyway, when the machine is turned on, and I let it 'listen' for incoming magic packets (with a program called "WOL magic packet sender") on my specified port, it does receive them, though when turned off, the machine does not wake. When sending from phone, either locally or via 3G remotely, it does receive but does not wake as well. Because the machine does receive them when turned on and listening, but does not wake when turned off, I am convinced the cause of the problem is my receiving PC, rather than the router or the sender. Some extra info: The receiving machine is a PC running Windows 7 64bit. My router is the Netgear JWNR2000v2. I have the port I use forwarded to my PC's static IP in the router. If anyone could help, or just share your own story with the same problem, maybe we can work this out. Thanks a lot in advance.

• Windows 7 caches FTP credentials?

  - by Martin Booka Weser

  On my remote maschine i have an iis 7.5 (win server 2008) and set up an ftp site with iis manager authentication. I then did active directory user isolation and isolated my users to physical folders according to their names. So far, so good. I can access with ftp cliens from everywhere with different test accounts that i previously set up in the iis manager auth. Every user connects to its own folder. When i now tested with windows 7 as a client i did the following. Explorer - computer - right click - add network address - the ip of my remote maschine - user1 - password1 Perfect - it works. I now want to connect with user2. So I deleted this network address and set up a new connection, but with user2 (or even anonymous) instead. Now the strange thing: Windows doesn't even ask me for a password again. It just connects me to the folder of the user1. I already disabled ftp caching in the IIS and i disabled the user1 account in IIS manager authentication! Still, if i set up a network connection with this windows 7 it connects to the folder user1 . No matter which username i use (anonymous, administrator, user2,...). And if i connect with other ftp clients or other computers it all works perfectly. So I assume that this one windows somehow caches the credentials... But then, why does the IIS still accepts this credentials even if i disabled this user1 account??? Thanks.

• pptp server 2003 hands out gateway from nic not dhcp server

  - by Pete

  I have created a pptp RRAS server for a handful of clients to connect to. I would like them to use the servers default gateway (.1) for internet access. They are able to successfully connect (& see LAN) but it then cuts them off the internet. I understand that all internet traffic would be routed through the pptp server but that's ok since I have enough pipe. The problem seems to be that: the clients gateway shows as their assigned RAS ip. The clients assigned DNS settings seem to be what is set to the servers nic not what I have specified in dhcp (which is the same server). DHCP relay agent properties points to the nic DHCP is running on (192.168.100.163). .1 is gateway in nic hw properties & dhcp. I have different dns secondary & third entries on my nic properties than what dhcp is configured for. The problem is that I have a 10.10.1.x network that people can not see if they uncheck the gateway option but, they are then unable to see our other hosted sites on the internet.

• Nginx order of servers

  - by scrat

  I have 3 sites on my server. All are running on gunicorn and use unix sockets to communicate with nginx which routes requests. I got three records in nginx.conf like: server { listen 80; server_name site1.com; location / { proxy_pass http://unix:/tmp/site1.sock; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } For site1, site2, site3. If they are ordered as config for site1 goes first, and then goes config for site2 and site3 everything works good. But when I change the order for example to site2, site1, site3, then site1 becomes routed to site2. What am I doing wrong? Full server nginx.conf before servers configs: user www-data; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_types text/css application/x-javascript text/x-component text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon;

• DHCP Relay setup in ubuntu server

  - by jerichorivera

  I have a network appliance (QNO) that works as traffic load balancer and dhcp server. I would like to add a linux server in between the network appliance and the client computers. The linux server will be used to monitor bandwidth usage. My problem is I still want DHCP to be served by the network appliance so that load balancing will still work efficiently. We are afraid that if we setup the linux server as the DHCP server the network appliance will not be able to load balance the traffic if it only sees the linux server as a single client connecting to it. I've been searching all over for a tutorial on how to setup DHCP relay but have not found any. How do I setup DHCP relay on my linux server given there are two NICs attached to it, one connects the linux server to the network appliance and the other connects the linux server to the client computers. EDIT Router (DHCP) ---- [eth0] Linux Server (Relay agent) [eth1] ----- PC (network) Router IP is 192.168.0.100 eth0 is on DHCP eth1 is static 192.168.2.11 (if I need to change this I can) Tried to do dhcrelay -i eth1 192.168.0.100, but the PC was not getting any DHCP lease from the DHCP router. I might be missing something here.

• Can't reliably ping 6224 router from directly-attached system

  - by David Mackintosh

  OK, here's my situation. This is on the internet. The 6224 is the router in this picture and physically resides in Kanata. Both VLAN 1697 and 3994 are provided by an internet service provider. These VLANs are provided through a single 1Gb ethernet wire. The Kanata hosts are directly attached to the 6224; the other two sites are remote. VLAN 3994 is a single IP address space, so theoretically it shouldn't matter physically where the hosts on that subnet are. Here's the problem. I have a monitoring system which is connected further into the internet, so probes from the monitor would come in to this diagram on the 1697 VLAN. When I ping hosts at Albert or Bells Corners from the internet, there is 0 loss. The connection looks perfect. When I ping hosts at Kanata, I lose anywhere from 10 to 40% of the pings. The loss is not predictable, but: when I do lose them, I always lose at least 3, usually 4, rarely more, pings in a bunch. I have attached a monitor directly to the 6224 in Kanata on 3994.. When the monitor pings the 6224 routing interface, I see exactly the same loss pattern -- but NOT at the same time as the loss from the remote system. Ping time is around 1ms. When the monitor pings another system directly attached to the 6224, there is 0 loss. Ping time is about 0.1ms, one-tenth of the time to ping the router. Anyone know what is going on here?

• Caching all files in varnish

  - by csgwro

  I want my varnish servers to cache all files. At backend there is lighttpd hosting only static files, and there is an md5 in the url in case of file change, ex. /gfx/Bird.b6e0bc2d6cbb7dfe1a52bc45dd2b05c4.swf). However my hit ratio is very poorly (about 0.18) My config: sub vcl_recv { set req.backend=default; ### passing health to backend if (req.url ~ "^/health.html$") { return (pass); } remove req.http.If-None-Match; remove req.http.cookie; remove req.http.authenticate; if (req.request == "GET") { return (lookup); } } sub vcl_fetch { ### do not cache wrong codes if (beresp.status == 404 || beresp.status >= 500) { set beresp.ttl = 0s; } remove beresp.http.Etag; remove beresp.http.Last-Modified; } sub vcl_deliver { set resp.http.expires = "Thu, 31 Dec 2037 23:55:55 GMT"; } I have made an performance tuning: DAEMON_OPTS="${DAEMON_OPTS} -p thread_pool_min=200 -p thread_pool_max=4000 -p thread_pool_add_delay=2 -p session_linger=100" The main url which is missed is... /health.html. Is that forward to backend correctly configured? Disabling health checking hit ratio increases to 0.45. Now mostly "/crossdomain.xml" is missed (from many domains, as it is wildcard). How can I avoid that? Should I carry on other headers like User-Agent or Accept-Encoding? I thing that default hashing mechanism is using url + host/IP. Compression is used at the backend. What else can improve performance?

• Freshly installed dd-wrt on dir-300 and no internet. What to do?

  - by Erik B

  With the d-link firmware I just connected the router and it worked, as is expected when using DHCP, but with dd-wrt I have no internet access. It is configured with DHCP, and dd-wrt's wan status page reports that it is connected and that it has an ip address. Yet it is impossible to reach the internet. If I disconnect the router and plugs the cable directly into my computer I get internet access, so it's obviously the dd-wrt software that isn't doing its job. However, I have no previous experience with the dd-wrt software and have no clue what to look for. I thought it would just work. By the way, the power led is orange, the internet led is off, and wireless+lan1 is green. They all used to be green with the d-link firmware. Not sure if it's relevant, but now you know. Does anyone have any idea what I should do to get internet access (besides reinstalling d-link's firmware)? EDIT: It's a version B1. I read that it is very different from the A1 version, so I thought it may be relevant.

• openvpn port 53 bypasses allows restrictions ( find similar ports)

  - by user181216

  scenario of wifi : i'm using wifi in hostel which having cyberoam firewall and all the computer which uses that access point. that access point have following configuration default gateway : 192.168.100.1 primary dns server : 192.168.100.1 here, when i try to open a website the cyberoam firewall redirects the page to a login page (with correct login information, we can browse internet else not), and also website access and bandwidth limitations. once i've heard about pd-proxy which finds open port and tunnels through a port ( usually udp 53). using pd-proxy with UDP 53 port, i can browse internet without login, even bandwidth limit is bypassed !!! and another software called openvpn with connecting openvpn server through udp port 53 i can browse internet without even login into the cyberoam. both of softwares uses port 53, specially openvpn with port 53, now i've a VPS server in which i can install openvpn server and connect through the VPS server to browse internet. i know why that is happening because with pinging on some website(eb. google.com) it returns it's ip address that means it allows dns queries without login. but the problem is there is already DNS service is running on the VPS server on port 53. and i can only use 53 port to bypass the limitations as i think. and i can not run openvpn service on my VPS server on port 53. so how to scan the wifi for vulnerable ports like 53 so that i can figure out the magic port and start a openvpn service on VPS on the same port. ( i want to scan similar vulnerable ports like 53 on cyberoam in which the traffic can be tunneled, not want to scan services running on ports). improvement of the question with retags and edits are always welcomed... NOTE : all these are for Educational purpose only, i'm curious about network related knowledge.....

• SBS2011 Standard DNS suddenly not resolving some domains

  - by Matt

  Suddenly today I am unable to resolve common domains like serverfault.com, facebook.com; but other domains like google.com, cnn.com work fine. This is on a client machine (Win7 Pro) connected to an SBS2011 Standard domain. The only DNS server is the SBS2011 server. The same domains work fine on all client PCs I have tried, and the same ones do not work. Using nslookup, I get 'no such domain' errors for facebook.com, and the correct DNS entries for the ones that do work. When I add Google's Public DNS to my client PC as a backup (primary = local SBS server, secondary = 8.8.8.8), everything works fine for my client PC, but querying from the SBS server directly or from other client PCs are broken (so I don't believe it's a firewall issue). My main question is how can I see what servers the SBS2011 server queries if it doesn't know about a domain? There is nothing in our firewall logs that say it blocked any DNS-based packets, but I also wanted to query based on the IP/FQDN on the servers that the SBS server was likely to contact to find out about facebook.com for example. Update 23/05/2012: It appears DNS is working again this morning for the affected websites. Both the DC on its own and all client PCs can once again access the websites that were not loading last night, as well as the websites that were working. I haven't changed anything overnight, so it appears that there was some kind of temporary glitch, but I can't understand what would have caused it on the network.

• Routing and authenticating all access through squid

  - by Knight Samar

  Hi, I want to route all Internet access in my network through a Squid proxy server and authenticate and log all users. I want this to be a client-independent setting so that no one needs to do anything on their browsers or machines. I have set my network gateway as the proxy server so that all traffic will be sent to it. I have done this using options in DHCP server. Now I tried using squid as a transparent proxy, but then it won't authenticate in that mode. I tried using iptables to route all traffic to port 3128 but it won't popup the authentication dialog box from SQUID. I tried telling DHCP to give WPAD to all clients by placing a WPAD file on a webserver containing the following for automatic proxy configuration on clients: Changes in dhcpd.conf option wpad code 252 =test; option wpad "\n\000"; option wpad "http://192.168.1.5/wpad.dat\n"; The WPAD file: function FindProxyForURL(url,host) { return "PROXY squid-server-ip-address:3128 ; DIRECT "; } But the browsers (different versions of Firefox and IE) seem to ignore it. :( What should I do ?

• Slow manipulation of netfilter rules

  - by Ole Martin Eide

  I have a script maintaining gre tunnels and firewall rules using the "ip" and "iptables" tools. Setting up hundreds of tunnels, and adresses per interface runs just fine. Takes less than 0.1 second per interface, however when I get around to do the firewall rules everything slows down spending 0.5 per insertion. Why is it running so slow? What can I do to improve the speed? It seems like I could try ipset instead, but I really feel there is something wrong with the kernel or something. The interesting thing is that the first 10 rules runs fast, then it slows down.. mybox(root) foo# iptables -V iptables v1.3.5 mybox(root) foo# uname -a Linux foo 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:48 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux mybox(root) foo# cat test.sh #!/bin/sh for n in {1..100} do /sbin/iptables -A OUTPUT -s ${n} -j ACCEPT /sbin/iptables -D OUTPUT -s ${n} -j ACCEPT done mybox(root) foo# time ./test.sh real 1m38.839s user 0m0.100s sys 1m38.724s Appriciate any help. Cheers!

• Ubuntu server apt-get says "(-5 - No address associated with hostname)"

  - by Srini

  I have a ubuntu 12.04 server. Running sudo apt-get update on it produces errors like this: W: Failed to fetch http://au.archive.ubuntu.com/ubuntu/dists/precise-backports/main/binary-i386/Packages Something wicked happened resolving 'au.archive.ubuntu.com:http' (-5 - No address associated with hostname) I am able to ping all the other hosts on the network and also Google's DNS 8.8.8.8. But am unable to ping www.google.com. So, I'm guessing something is wrong with my DNS setup, but not sure what. I use static IP and my /etc/network/interfaces looks like this: auto eth0 iface eth0 inet static address 192.168.1.50 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.0.255 gateway 192.168.1.1 #dns-nameserver 203.12.160.35 203.12.160.36 #nameserver 203.12.160.35 203.12.160.36 My /etc/resolv.conf and /etc/resolvconf/resolv.conf.d/base are both empty and my /etc/resolvconf/resolv.conf.d/original says: nameserver 192.168.1.1 Any help would be greatly appreciated. P.S. I've googled it a bit and the common resolution is to switch to DHCP which I don't want to do since this is my home server. Thanks Srini

• nginx redirect what is not coming from load balancing

  - by dawez

  I have nginx on SERVER1 that is acting as load balancing between SERVER1 and SERVER2 in SERVER1 I have the upstreams for the load balancing defined as : upstream de.server.com { # similar upstreams defined also for other languages # SELF SERVER1 server 127.0.0.1:8082 weight=3 max_fails=3 fail_timeout=2; # other SERVER2 server otherserverip:8082 max_fails=3 fail_timeout=2; } The load balancing config on SERVER1 is this one: server { listen 80; server_name ~^(?<LANG>de|es|fr)\.server\.com; location / { proxy_pass http://$LANG.server.com; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # trying to pass a variable in the header to SERVER2 proxy_set_header Is-From-Load-Balancer 1; } } Then in server 2 I have: server { listen 8082; server_name localhost; root /var/www/server.com/public; # test output values add_header testloadbalancer $http_is_from_load_balancer; add_header testloadbalancer2 not_load_bal; ## other stuff here to process the request } I can see the "testloadbalancer" in the response header is set to 1 when the request is coming from the load balancing, it is not present when from a direct access: SERVER2:8082 . I would like to bounce back to the SERVER1 all the direct requests that are sent to SERVER2, but keep the ones from the load balancing. So this should forbid direct access to SERVER2:8082 and redirect to SERVER1:80 .

• Nginx, as reverse proxy, could not proxy_pass to a domain pointing to the local JBOSS

  - by larryzhao

  My environment is Ubuntu 12.04, Nginx 1.20, and Torquebox 2.0.3 which is actually JBoss AS 7. I have two app deployed on Torquebox, it listens to 8080 and have different hostnames, app1.mydomain.com and app2.mydomain.com. I added 127.0.0.1 app1.mydomain.com and 127.0.0.1 app2.mydomain.com in /etc/hosts then I curl app1.mydomain.com:8080 and curl app2.mydomain.com:8080 both have correct return. Then I go to my nginx. I would like nginx to pass the visit to www.app1.com to app1.mydomain.com:8080, so I have the following configuration: # primary server - proxypass to torquebox server { listen 80; server_name www.app1.com; access_log off; error_log off; # proxy to Torquebox location / { proxy_pass http://app1.mydomain:8080/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_max_temp_file_size 0; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } But it doesn't work. curl www.app1.com returns nothing. And if I visit www.app1.com in Safari, the http return code is 404. I don't know why, need help.
