  • Unexpected network traffic?

    - by robwalker
    My internet connection is via a fixed wireless connection using a 900MHz Motorola Canopy module. The router reports a fairly consistent 32-64Kbps of incoming traffic on the WAN port. When I attached a PC directly to the port and run Wireshark, I get a dump showing a lot of chatter from other machines that I presume are connected to the same tower. This didn't include end-to-end traffic, but was there were a lot of ARP requests, SSDP traffic, ICMP and other network discovery type stuff. Is this 'normal' or does it suggest a misconfiguration somewhere? As far as I can tell there is no need for my modem to be receiving any of this traffic (other than wanting to know what the names of my neighbours machines and printers are!) Since the internet connection is slow at the best of time, having this amount of background noise seems very wasteful.

  • curl can't verify cert using capath, but can with cacert option

    - by phylae
    I am trying to use curl to connect to a site using HTTPS. But curl is failing to verify the SSL cert. $ curl --verbose --capath ./certs/ --head https://example.com/ * About to connect() to example.com port 443 (#0) * Trying 1.1.1.1... connected * Connected to example.com (1.1.1.1) port 443 (#0) * successfully set certificate verify locations: * CAfile: none CApath: ./certs/ * SSLv3, TLS handshake, Client hello (1): * SSLv3, TLS handshake, Server hello (2): * SSLv3, TLS handshake, CERT (11): * SSLv3, TLS alert, Server hello (2): * SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed * Closing connection #0 curl: (60) SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed More details here: http://curl.haxx.se/docs/sslcerts.html curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option. I know about the -k option. But I do actually want to verify the cert. The certs directory has been properly hashed with c_rehash . and it contains: A Verisign intermediate cert Two self-signed certs The above site should be verified with the Verisign intermediate cert. When I use the --cacert option instead (and point directly to the Verisign cert) curl is able to verify the SSL cert. $ curl --verbose --cacert ./certs/verisign-intermediate-ca.crt --head https://example.com/ * About to connect() to example.com port 443 (#0) * Trying 1.1.1.1... connected * Connected to example.com (1.1.1.1) port 443 (#0) * successfully set certificate verify locations: * CAfile: ./certs/verisign-intermediate-ca.crt CApath: /etc/ssl/certs * SSLv3, TLS handshake, Client hello (1): * SSLv3, TLS handshake, Server hello (2): * SSLv3, TLS handshake, CERT (11): * SSLv3, TLS handshake, Server finished (14): * SSLv3, TLS handshake, Client key exchange (16): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSL connection using RC4-SHA * Server certificate: * subject: C=US; ST=State; L=City; O=Company; OU=ou1; CN=example.com * start date: 2011-04-17 00:00:00 GMT * expire date: 2012-04-15 23:59:59 GMT * common name: example.com (matched) * issuer: C=US; O=VeriSign, Inc.; OU=VeriSign Trust Network; OU=Terms of use at https://www.verisign.com/rpa (c)10; CN=VeriSign Class 3 Secure Server CA - G3 * SSL certificate verify ok. > HEAD / HTTP/1.1 > User-Agent: curl/7.19.7 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15 > Host: example.com > Accept: */* > < HTTP/1.1 404 Not Found HTTP/1.1 404 Not Found < Cache-Control: must-revalidate,no-cache,no-store Cache-Control: must-revalidate,no-cache,no-store < Content-Type: text/html;charset=ISO-8859-1 Content-Type: text/html;charset=ISO-8859-1 < Content-Length: 1267 Content-Length: 1267 < Server: Jetty(7.2.2.v20101205) Server: Jetty(7.2.2.v20101205) < * Connection #0 to host example.com left intact * Closing connection #0 * SSLv3, TLS alert, Client hello (1): In addition, if I try hitting one of the sites using a self signed cert and the --capath option, it also works.

  • Some notebooks can connect to internet via certain wireless router, some can't

    - by Nathaniel
    I take a class in the building of a business and we sometimes use their internet via Wi-Fi. In the last few weeks, though, some notebooks haven't been able to connect to the internet even though they are connected to the router. It affected first a few of us and then all of us. Last week I tweaked around the network settings on the router (yes, the admin password is the same as the network key) and even moved the internet cable on the router from port 1 to the internet port. None of this really worked so I put things more or less back as I found them and alerted someone that someone who knew more than me had better have a look at the router. So, I don't know if anybody has had a look at it but now 2 of us can again connect to the internet. I had a look at the router settings last week and I really couldn't see what might be creating this issue. What might be the problem?

  • Securing a persistent reverse SSH connection for management

    - by bVector
    I am deploying demo Ubuntu 10.04 LTS servers in environments I do not control and would like to have an easy and secure way to administer these machines without having to have the destination firewall forward port 22 for SSH access. I've found a few guides to do this with reverse port (e.g. howtoforge reverse ssh tunneling guide) but I'm concerned with security of the stored ssh credentials required for the tunnel to be opened automatically. If the machine is compromised (primary concern is physical access to the machine is out of my control) how can I stop someone from using the stored credentials to poke around in the reverse ssh tunnel target machine? Is it possible to secure this setup, or would you suggest an alternate method?

  • 2wire modem to linksys router

    - by Imajica666
    I want to hook a Linksys router to my 2wire modem/router (2701HG-b) to share my Internet connection. I ran from an open port from the 2wire to the WAN port of the Linksys but it will not work. I did this before with my cable modem to a router to my Linksys router. It worked then but not now. I read I can turn the 2 wire into a modem only but I need the 2wire wireless access also. IPCONFIG /ALL sees the 2wire with IP info as well as DHCP server/gateway. Any ideas?

  • SSH stops at "using username" with IPTables in effect

    - by Rautamiekka
    We used UFW but couldn't make the Source Dedicated ports open, which was weird, so we purged UFW and switched to IPTables, using Webmin to configure. If the inbound chain is on DENY and SSH port open [judged from Webmin], PuTTY will say using username "root" and stops at that instead of asking for public key pw. Inbound chain on ACCEPT the pw is asked. This problem didn't happen with UFW. Picture of IPTables configuration in Webmin: http://s284544448.onlinehome.us/public/PlusLINE%20Dedicated%20Server,%20Webmin,%20IPTables,%200.jpgThe address is to the previous rautamiekka.org. iptables-save when on INPUT DENY: # Generated by iptables-save v1.4.8 on Wed Apr 11 16:09:20 2012 *mangle :PREROUTING ACCEPT [1430:156843] :INPUT ACCEPT [1430:156843] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [1415:781598] :POSTROUTING ACCEPT [1415:781598] COMMIT # Completed on Wed Apr 11 16:09:20 2012 # Generated by iptables-save v1.4.8 on Wed Apr 11 16:09:20 2012 *nat :PREROUTING ACCEPT [2:104] :POSTROUTING ACCEPT [0:0] :OUTPUT ACCEPT [0:0] COMMIT # Completed on Wed Apr 11 16:09:20 2012 # Generated by iptables-save v1.4.8 on Wed Apr 11 16:09:20 2012 *filter :INPUT DROP [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [1247:708906] -A INPUT -i lo -m comment --comment "Machine-within traffic - always allowed" -j ACCEPT -A INPUT -p tcp -m comment --comment "Services - TCP" -m tcp -m multiport --dports 22,80,443,10000,20,21 -m state --state NEW,ESTABLISHED -j ACCEPT -A INPUT -p tcp -m comment --comment "Minecraft - TCP" -m tcp --dport 25565 -j ACCEPT -A INPUT -p udp -m comment --comment "Minecraft - UDP" -m udp --dport 25565 -j ACCEPT -A INPUT -p tcp -m comment --comment "Source Dedicated - TCP" -m tcp --dport 27015 -j ACCEPT -A INPUT -p udp -m comment --comment "Source Dedicated - UDP" -m udp -m multiport --dports 4380,27000:27030 -j ACCEPT -A INPUT -p udp -m comment --comment "TS3 - UDP - main port" -m udp --dport 9987 -j ACCEPT -A INPUT -p tcp -m comment --comment "TS3 - TCP - ServerQuery" -m tcp --dport 10011 -j ACCEPT -A OUTPUT -o lo -m comment --comment "Machine-within traffic - always allowed" -j ACCEPT COMMIT # Completed on Wed Apr 11 16:09:20 2012 iptables --list when on INPUT DENY: Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere /* Machine-within traffic - always allowed */ ACCEPT tcp -- anywhere anywhere /* Services - TCP */ tcp multiport dports ssh,www,https,webmin,ftp-data,ftp state NEW,ESTABLISHED ACCEPT tcp -- anywhere anywhere /* Minecraft - TCP */ tcp dpt:25565 ACCEPT udp -- anywhere anywhere /* Minecraft - UDP */ udp dpt:25565 ACCEPT tcp -- anywhere anywhere /* Source Dedicated - TCP */ tcp dpt:27015 ACCEPT udp -- anywhere anywhere /* Source Dedicated - UDP */ udp multiport dports 4380,27000:27030 ACCEPT udp -- anywhere anywhere /* TS3 - UDP - main port */ udp dpt:9987 ACCEPT tcp -- anywhere anywhere /* TS3 - TCP - ServerQuery */ tcp dpt:10011 Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere /* Machine-within traffic - always allowed */ The UFW rules prior to purging on INPUT DENY: 127.0.0.1 ALLOW IN 127.0.0.1 3306 DENY IN Anywhere 20,21/tcp ALLOW IN Anywhere 22/tcp (OpenSSH) ALLOW IN Anywhere 80/tcp ALLOW IN Anywhere 443/tcp ALLOW IN Anywhere 989 ALLOW IN Anywhere 990 ALLOW IN Anywhere 8075/tcp ALLOW IN Anywhere 9987/udp ALLOW IN Anywhere 10000/tcp ALLOW IN Anywhere 10011/tcp ALLOW IN Anywhere 25565/tcp ALLOW IN Anywhere 27000:27030/tcp ALLOW IN Anywhere 4380/udp ALLOW IN Anywhere 27014:27050/tcp ALLOW IN Anywhere 30033/tcp ALLOW IN Anywhere

  • PHP hits 100% CPU and eats RAM at the same time Monday to Friday

    - by Daniel Samuels
    We run a learning platform for primary schools here in the UK and it's all been running extremely well. However at around 4PM Monday to Friday we see the same issue arise -- 1-2 PHP threads will spike to 100% CPU and gradually start eating up RAM until the server(s) fall over. 98%+ of our requests are HTTPS, these come into our Layer 7 load balancer which then decrypts the SSL data, adds the X-HTTP-Forwarded-For header and forwards the data onto an application server (we have 2 of those at the moment) on port 80. Our application servers have Varnish on port 80 which takes in the request from the load balancer and passes the request through to Nginx on port 81. Nginx then works out which 'vhost' it needs to use and passes any PHP processing through to PHP-CGI which is listening on a socket (managed through spawn-fcgi). There's an instance of Memcached running too, MySQL runs on a separate server / slave setup. Throughout the day the load will typically go no higher than 0.8 on either of the application servers, however at around 4PM our problem arises. I've managed to run strace on a few of the actual threads when they cause the problem and I always see the same thing: stat("/usr/share/zoneinfo/Europe/London", {st_mode=S_IFREG|0644,st_size=3661, ...}) = 0 stat("/usr/share/zoneinfo/Europe/London", {st_mode=S_IFREG|0644,st_size=3661, ...}) = 0 This is repeated infinitely and never stops until you SEGKILL the process or oomkiller kills it. There are no cron jobs scheduled to run at that time and I don't have any way of seeing exactly what Nginx request is associated with the PHP process which is running. We are running PHP 5.3.14 which we upgraded to from 5.3.8 last week to rule out the older version being the problem. This issue has been going on a few months now and we have no idea what is causing it. We deploy our software very frequently, so it's difficult to track down a specific release which may have started the problem - especially as we do not know the date of the first occurrence of this issue. Varnish is version 3.0.1, Nginx is 1.0.6 (which I understand is about a year old now), our servers are running CentOS release 5.7 (Final) they have Intel i3 540s at 3.07Ghz and 8GB of RAM. There's a discussion on the Debian mailing list about something very similar, you can find that here. Has anyone seen anything like this in the past, does anyone have any ideas or suggestions? Are there a way of linking an Nginx request directly to a PHP thread? Is there a better way of seeing what the PHP process is doing? (I've seen GDB mentioned, though I'll have to recompile PHP) Thanks!

  • Proxy Error 502 "Reason: Error reading from remote server" with Apache 2.2.3 (Debian) mod_proxy and Jetty 6.1.18

    - by Martin
    Apache is receiving requests at port :80 and proxying them to Jetty at port :8080 The proxy server received an invalid response from an upstream server The proxy server could not handle the request GET /. My dilemma: Everything works fine normally (fast requests, few seconds or few tens of seconds long requests are processed ok). Problems occur when request processing takes long (few minutes?). If I issue request instead directly to Jetty at port :8080 the request is processed OK. So problem is likely to sit somewhere between Apache and Jetty where I am using mod_proxy. How to solve this? I have already tried some "tricks" related to KeepAlive settings, without luck. Here is my current configuration, any suggestions? #keepalive Off ## I have tried this, does not help #SetEnv force-proxy-request-1.0 1 ## I have tried this, does not help #SetEnv proxy-nokeepalive 1 ## I have tried this, does not help #SetEnv proxy-initial-not-pooled 1 ## I have tried this, does not help KeepAlive 20 ## I have tried this, does not help KeepAliveTimeout 600 ## I have tried this, does not help ProxyTimeout 600 ## I have tried this, does not help NameVirtualHost *:80 <VirtualHost _default_:80> ServerAdmin [email protected] ServerName www.mydomain.fi ServerAlias mydomain.fi mydomain.com mydomain www.mydomain.com ProxyRequests On ProxyVia On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyRequests Off ProxyPass / http://www.mydomain.fi:8080/ retry=1 acquire=3000 timeout=600 ProxyPassReverse / http://www.mydomain.fi:8080/ RewriteEngine On RewriteCond %{SERVER_NAME} !^www\.mydomain\.fi RewriteRule /(.*) http://www.mydomain.fi/$1 [redirect=301L] ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

  • What's causing "shutdown state" after TFTP reloaded Cisco `running-config` on 871?

    - by xtian
    Cisco CCP Write Configuration borked my 871w config while I was trying to setup port forwarding. I tested the 871's flash memory with fsck and rewrote the minimal config for TFTP (which is the same for Cisco's CCP app.). Thne, I successfully uploaded a previously working running-config from Win Vista using SolarWinds TFTP Server, unfortunately the restore was not entirely successful. The old running config was saved to the 871's startup-config and I can login using console port. Some other things that are working are the hostname and welcome message but that's about it. Startup shows an error SETUP: new interface NVI0 placed in "shutdown" state after tftp. The missing light on the access point modem for ethernet link show the 871'a outside FE4 is not working. SO...what's the possible problem with reloading a previously working config (approximately 4 months with the same config) via TFTP? Is there something I can look for on the 871 to verify the config?

  • external HDD with SATA & USB interface?

    - by Greg
    Anyone know of an external HDD that would have (in addition to USB) a SATA (eSATA) port/cable? i.e. Brand/Model. Preferably one of the name brands so I have a better change of finding it here or locally if possible. Background - In one location I want to use it is I would like to increase the performance by cabling it directly to the PC SATA port, HOWEVER I don't want to have to open up the PC to do this each time. I was thinking of running a SATA cable out through the PC case so I just plug it directly into the external HDD in question. Perhaps it should be also externally powered too so I don't need to run a power cable out from the PC power supply.

  • Can't bring NAT to work

    - by user31738
    Hello, I bought a D-link DIR-300 wireless router and i can't bring NAT to work, i have an ssh and http service i need to forward to the internet. My connection is as follows: I have an ADSL connection, i'm using a ADSL ethernet modem connected and working, it doesnt let me put it on bridge mode. I have my router connected to my adsl modem through ethernet, it gets its ip through DHCP (and i'ts always the same) I have a desktop computer running linux with apache and openssh configured and working, it has fixed ip. I configured the NAT in the modem forwarding port 22 from the router ip to the internet. In the router i setup NAT forwarding port 22 from the desktop computer fixed ip to out there. This setup already worked with a fonera i had before, can anyone help me with this or tell me what kind of tests do i need to do? How can i test if the router is forwarding ports correctly before the modem?

  • Cannot access internet or remote network after connecting to Windows VPN

    - by Kiewic
    I set up a VPN by creating an incoming VPN connection (VPN server) in my Windows 8 machine at home (not a Windows Server). I forwarded the PPTP port in my router (port 1723) to this machine and enabled PPTP passthrough. In a second Windows 8 machine out of home, I created an outgoing VPN connection (VPN client). And I am able to connect to my home VPN, but I don't have access to any home resource or even internet. This is the output of the client ipconfig: And this are the settings of my VPN server: UPDATE: My VPN server has assigned the 192.168.1.144 IP adress at my home network. So, I tried setting the "IP address assignment" range from 192.168.1.150 to 192.168.1.200. And when a VPN client gets connected, it gets an address in that range, but it doesn't make any difference.

  • Ubuntu hardware wireless switch has no effect after suspend and 13.10 upgrade

    I'm posting this on SU after it stalled on askubuntu. I hope someone here can help! If you'd prefer to answer on AU itself, here's the link: http://askubuntu.com/questions/365177/hardware-wireless-switch-has-no-effect-after-suspend-and-13-10-upgrade Wireless works fine after a reboot, but after a suspend the hardware switch (for my laptop this is f12) has no effect on the wireless, it is just permanently off, and shows that it is with a red LED. My rfkill list all reads: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes Any combination with rfkill <un>block wifi doesn't work, although one time first blocking then unblocking actually turned it on again. sudo lshw -C network reads: *-network DISABLED description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 01 serial: 78:e4:00:65:2e:3f width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=3.11.0-12-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:90100000-9010ffff *-network DISABLED description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 02 serial: c8:0a:a9:89:b4:30 size: 10Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:42 ioport:2000(size=256) memory:90010000-90010fff memory:90000000-9000ffff memory:90020000-9002ffff Also, adding a /etc/pm/sleep.d/brcm.sh file as recommended here simply prevents the laptop from suspending at all, which of course is no good. This question has an answer urging to install the original driver, but it wasn't an "accepted answer" so I'd rather not take a chance on it. Also I'll admit I'm a bit lost on that and would like help doing so with the specific information I've given. I would be happy to provide more information, so long as you're willing to help me find it for you! This is a very annoying bug. I have a Compaq Presario CQ62. Edit. Output of lspci | grep Network: 02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01) Edit. This morning, I had had the laptop suspended all night, and then when I tried to awake it, it simply wouldn't. It would try, and then it would sleep again (I guess it felt a little bit like me! </badjoke>). Is it possible these problems are related? Edit. I don't have enough reputation on SU proper to post links to pastebins and other questions I've tried, so I'm putting them in comments, and of course they're available in the original question.

  • Concerns about a Dedicated (Windows Server 2008) + DDoS

    - by TheKillerDev
    I am have today a dedicated server with these specs: Intel Core i5 750, 2x120GB (ssd + raid), Windows Server 2008 Web, 200Mbps Network, 24 Gb DD3 And I would like to know what are the best thing I can do to prevent a DDoS Attack, since I know this will be a real threat by the importance of the files that will be archived in it. Today I have apache listening port 80 and RDC listening port 3389. But the security is beeing made only by Windows Firewall. So, any thoughts on what would be good to prevent from DDoS attacks?

  • Setting up wifi router as a switch for Internet Connection Sharing

    - by William C
    Can my laptop with a 3G connection share its Internet via a Wifi router (Dlink DIR-615)? I turned Internet Connection Sharing on and Windows assigned 192.168.137.1 to my laptop's LAN adapter. Do I connect my laptop to the WAN port or to the LAN port of the router? What should I set as my router's IP address? Do I turn DHCP on my router on? Do I assign 192.168.137.x as static addresses on the other computers? If not, what? Is there anything else I need to set on my router? Thank you!

  • Nginx, proxy passing to Apache, and SSL

    - by Vic
    I have Nginx and Apache set up with Nginx proxy-passing everything to Apache except static resources. I have a server set up for port 80 like so: server { listen 80; server_name *.example1.com *.example2.com; [...] location ~* \.(?:ico|css|js|gif|jpe?g|png|pdf|te?xt)$ { access_log off; expires max; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; add_header Vary: Accept-Encoding; } location / { proxy_pass http://127.0.0.1:8080; include /etc/nginx/conf.d/proxy.conf; } } And since we have multiple ssl sites (with different ssl certificates) I have a server{} block for each of them like so: server { listen 443 ssl; server_name *.example1.com; [...] location ~* \.(?:ico|css|js|gif|jpe?g|png|pdf|te?xt)$ { access_log off; expires max; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; add_header Vary: Accept-Encoding; } location / { proxy_pass https://127.0.0.1:8443; include /etc/nginx/conf.d/proxy.conf; proxy_set_header X-Forwarded-Port 443; proxy_set_header X-Forwarded-Proto https; } } server { listen 443 ssl; server_name *.example2.com; [...] location ~* \.(?:ico|css|js|gif|jpe?g|png|pdf|te?xt)$ { access_log off; expires max; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; add_header Vary: Accept-Encoding; } location / { proxy_pass https://127.0.0.1:8445; include /etc/nginx/conf.d/proxy.conf; proxy_set_header X-Forwarded-Port 443; proxy_set_header X-Forwarded-Proto https; } } First of all, I think there is a very obvious problem here, which is that I'm double-encrypting everything, first at the nginx level and then again by Apache. To make everything worse, I just started using Amazon's Elastic Load Balancer, so I added the certificate to the ELB and now SSL encryption is happening three times. That's gotta be horrible for performance. What is the sane way to handle this? Should I be forwarding https on the ELB - http on nginx - http on apache? Secondly, there is so much duplication above. Is the best method to not repeat myself to put all of the static asset handling in an include file and just include it in the server?

  • Varnish VCL not allowing two separate IP addresses as backends

    - by Peter Griffin
    Every time I attempt to add an extra back end into our VCL file, it's fails. Here is the DAEMON_OPTS we are running off: DAEMON_OPTS="-a :80 \ -T localhost:6082 \ -f /etc/varnish/custom.vcl \ -u varnish -g varnish \ -S /etc/varnish/secret \ -s malloc,10G" And here is the offending backend(s) backend default { .host = "114.123.456.789"; .port = "8080"; } backend alt { .host = "203.123.456.789"; .port = "80"; } Any Ideas ? Gut feeling is it might need the backends to be set somewhere, but I'm not sure where.

  • Reverse proxy using hop and RDP

    - by Sergei
    I am trying to connect from Vista to XP using RDP via reverse proxy using putty and an intermidiate host. There are myriad articles on the internet how to do it using vnc, ssh servers, winsshd, etc, but I can't find anything that helps me in this specific case. What I have: Windows XP host behind the firewall - 'destination' linux host running ssh on the internet - 'intermediate' windows host behind the firewall - 'source' All I want to do is open reverse tunnel from destination to intermidiate and use this tunnel for connecting back from the source. That should be simple to setup, however I just cannot make it. This is what I do: On 'destination', open putty session, create tunnel to 'intermediate' using following settings: source port 3389, destination is 'source:33389', direction is local On 'source', open putty session, create tunnel to 'intermediate'using following settings: source port 33389, destination is 'destination:33389', direction is local Finally, on source, open termnal services client and connect it to localhost:33389.Unfortunately it seems like packets do go somewhere but eventually client times out. Am I totally misunderstanding the concept? Please help!

  • Computer suddenly dies; screen displays weird flickering lines, then restarts

    - by Imray
    I've been having this terrible problem for a little while and just managed to get a picture of 'dead screen' for the first time and I am posting it to seek help. Randomly, at irregular intervals (typically once a week), while working on something (it's been different things every time) my computer will just suddenly go dead - the screen turns to exactly the picture below (the lines flicker a little bit), it hangs there for a few seconds and then restarts. Obviously this is extremely frustrating and I want to try to stop it. I've searched numerous postings with similar keywords but nothing exactly the same as mine. Does anyone have any idea what might be the cause of this? I would post all my system settings and installed programs but the list is long and I don't know how much relevance each item would be. If you'd like to know something specific, please comment and I'll let you know whatever you need.
