• can't register a soft phone to asterisk11

  - by Tom

  I have a VM (on oracle vbox) running Fedora17. I've installed asterisk 11 on it from sources. I've followed the wiki for installation (https://wiki.asterisk.org/wiki/display/AST/Creating+SIP+Accounts) to the letter. The ip on the VM machine running fedora is 192.168.1.7 and I can ping it from the host machine (Ubuntu 12.04), which is at 192.168.1.2 I've tried registering with ekiga with the following settings: user: [email protected]. Password: verysecretpassword registar: 192.168.1.7 but I'm getting an error "transport fail". Also, while trying to register I'm logged in to the asterisk CLI with verbose level 3 and debug level 4 and nothing appears. some more relevant data: I've added the following code to the end of my sip.conf.sample file: [demo-alice] type=friend host=dynamic secret=verysecretpassword context=users deny=0.0.0.0/0 permit=192.168.1.0/255.255.255.0 [demo-bob] type=friend host=dynamic secret=othersecretpassword context=users deny=0.0.0.0/0 permit=192.168.1.0/255.255.255.0 After I changed the sip.conf.sample file, I've created a copy of it and named it sip.conf. then I logged in to the asterisk CLI and typed sip reload. Then I'm trying to register and ekiga client from my host machine at 192.168.1.2 but it doesn't work and nothing appears on the asterisk CLI while in verbose mode level 3. BTW, If there is missing information about my question, please don't close it. comment about what you need to know and I'll edit it in to the question. tnx.

• Libvirt/KVM in NAT: can't access from host (and can't forward)

  - by SharkWipf

  I'm trying to set up a port forward to a KVM guest, managed through Libvirt on Debian 6. The VM is running in NAT, through the "default" network. This all runs fine, the VM has full internet connection. However, the host cannot reach the vm internally. Neither ping, nc nor nmap on the NAT network give any signs of the VM. Due to this, the normal iptables forwarding rules don't work either. $ cat /etc/debian_version 6.0.5 $ libvirtd --version libvirtd (libvirt) 0.9.11.3 $ kvm --version QEMU emulator version 1.0 (qemu-kvm-1.0+dfsg-11, Debian), Copyright (c) 2003-2008 Fabrice Bellard ifconfig: eth0 Link encap:Ethernet HWaddr 54:04:a6:f1:6f:10 inet addr:x.x.x.x Bcast:x.x.x.x Mask:255.255.255.x inet6 addr: fe80::5604:a6ff:fef1:6f10/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:118902 errors:0 dropped:0 overruns:0 frame:0 TX packets:142357 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:13247173 (12.6 MiB) TX bytes:95163190 (90.7 MiB) Interrupt:28 Base address:0xe000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:230646 errors:0 dropped:0 overruns:0 frame:0 TX packets:230646 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:204577107 (195.0 MiB) TX bytes:204577107 (195.0 MiB) virbr0 Link encap:Ethernet HWaddr fe:54:00:e2:d2:60 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5050 errors:0 dropped:0 overruns:0 frame:0 TX packets:961 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:666759 (651.1 KiB) TX bytes:400701 (391.3 KiB) vnet0 Link encap:Ethernet HWaddr fe:54:00:e2:d2:60 inet6 addr: fe80::fc54:ff:fee2:d260/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5050 errors:0 dropped:0 overruns:0 frame:0 TX packets:125687 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:739803 (722.4 KiB) TX bytes:6886609 (6.5 MiB)

• Windows Server 2008 is stuck at "configuring updates - stage 3 of 3 - 0% complete"

  - by Chris

  This has happened the last two times I've done updates to this system, and I really have no idea what is going on. It is installing a only a month's worth of updates. It only responds to ping and no services are up, so I can't view the system remotely (I have to hook up a monitor to see this message). In the past I've just restarted the system at this point and it eventually finishes updating. I want to know what I can do to avoid this situation, how to diagnose what is going on, and how to get any kind of remote access during the updates. Edit: I can start the machine in safe mode (where I did nothing but backup some files). I restarted and it no longer tries to do a windows update, just goes to the desktop where everything seems extremely broken. I can click on some things, but not launch most programs. I guess all I can do at this point is do a system restore or something. Edit: Re-installed windows on this system yesterday. That's my usual solution to issues I don't feel like diagnosing, like this one.

• Linux Centos 6 becomes unavailable from time to time - OS&network issue

  - by adoado0

  I am encountering following problem. There is one server (DL160 G5) running Centos 6.3 with default kernel 2.6.32-220.2.1.el6.x86_64 - at this point I'd like to add that issue appeared also at older version - 6.1 and older kernel (do not remember exactly which version). There is cPanel installed and from time to time it becomes unavailable (network connection). What I've checked is (via KVMoIP): load average is completely normal it does not lack memory or disk space when problem occurs no console notifications checked all access logs and there is no sign that it can be caused by a client script cannot even access local interface (127.0.0.1) or main IP address running tcpdump I can only see packets arriving to server - no responses all services seem to be running properly (mail,sql,http,ssh) checked crontab and all clients' crontabs too network port utilisation is low ( up to several Mbits) arriving packet rate is low - hundreds per second (according to tcpdump) console (via kvmoip) works fine, no lags there is no conntrack at this server there is no ipv6 at this server flushing iptables, unloading modules does not resolve problem restarting network does not resolve problem, no errors appear it also occurs when two sepearate networks are configured (and multiple gateways) as well as one IP, one default gw and one network is configured - so it seems network configuration independent it seems to repeat randomly (load,packet rate,bandwith usage,load independent) checked server with different rootkit detection tools - it seems to be clean server has been rebooted, it did not change anything there are no interface errors it apperas randomly can be once a week or several times per day It usually works fine after 1-15 minutes. What I can also check? It is definitely OS issue - there is traffic at interface only in one direction when problem occurs, can not even ping loopback. Any ideas? Recommended checks? Anything I did not checked above.

• 2 routers at home- how to connect with VNC?

  - by Charles Leviton

  I have two routers at home. First router is upstairs and is connected to the cable modem. 2nd router is downstairs and acts as "signal booster" for the 1st router. Devices connected to the upstairs router have IP addresses of the form 192.168.1.n Devices connected to the upstairs router have IP addresses of the form 192.168.2.n. I blindly followed instructions from a website to do this set up, just glad it works! Upstairs I have a PC running Win 7 64 bit. Its assigned IP is 192.168.1.7. I have a VNC viewer running on this. Downstairs I have a 2nd PC running Vista 32 Home edition bit that is connected to the 2nd router and has IP Address 192.168.2.114. VNC server is running on this. It's listening on 5900. There is no firewall. When I try to connect to this downstairs PC from upstairs it fails with message "Failed to connect to server". I cannot ping to this either. If I try to connect to this downstairs PC using VNC Viewer from another computer that's connected to the same downstairs router then it works like a charm. So what's the work around if the viewer is on a different "network"? I don't have any problems doing remote desktop connection from the downstairs PC to the upstairs PC even if they are connected to different routers. Router information- Upstairs- ASUS RTN13U, downstairs- DD-WRT v24 RC-5 Thanks! P.S. I posted this on the Ultra VNC forum as well but that doesn't seem to have a lot of activity, so taking the liberty to multipost.

• Window 7 image in vmware will allow network connection out but not http

  - by Ormis

  I am currently trying to create a set of images to deploy on my network, but I've run in to a snag. When I create my own Windows 7 image I can successfully use NAT for connecting to the network but whenever I try to access a webpage I get nothing. To be more specific, All firewalls/iptables are disabled on my host machine, my virtual machine, and my network. I can do lookups and all addresses respond correctly (i'm even using Google's DNS). On the host OS i have full connectivity. On the virtual machine I can ping any device I want and all addresses resolve correctly. Within a browser I cannot reach any page via hostname or IP. I feel almost like port 80 is being blocked but i can't find any reason this would be the case. If anyone has had this occur before, I would love some insight to the problem. I initially asked this on stackoverflow and now my eyes are now opened up to superuser. Thank you for any help you can provide.

• Why does the wireless network icon have a red X over it when everything seems to work?

  - by Kristo

  I booted my almost brand new laptop running Windows 7 this morning and noticed a red X through the wireless networking icon in the system tray. At first I thought something was wrong, but clicking on it shows a good connection to my wireless network. I had no problem getting here to post this question. I'm very new to Windows 7 so I have no idea how to troubleshoot this myself. Is there an actual problem here? Can I fix the icon so it doesn't falsely display an error (I assume that's what the red X means)? Here's what I know: I can get here to post this question. There's at least one unsecured network available that I'm not connected to. I can see a bunch of wireless networks, presumably from my neighbors' houses. There are no other computers turned on in my house right now. The device manager shows no problems with any devices. I can ping my default gateway, DNS, and yahoo.com with no problem.

• 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

• 2 Computers, same network, different outgoing speeds when uploading to internet?

  - by user117339

  I have 2 work machines in my office, a PowerMac G5 and a MacBook Air. Both behind an IPCop firewall. The PowerMac is connected through a gigabit switch, the MacBook Air is connected through a Netgear 802.11g access point that is then plugged into the gigabit switch. There is also a FreeNAS box, both machines are able to read and write files to it at close to their pipe speeds. The main problem is when I am trying to upload files to the internet at large. The G5 is only hitting 0.1 - 0.25 Mbps. The Macbook is able to hit 2-3 Mbps. The setup (G5 / IPCop / Network) has been the same for 5 years. The issues with the internet speed started about 3 months ago. I hadn't tested on the Macbook at this point. I had complained to the ISP, they said their modem needed a firmware update, did that nothing changed. Reset IPCop, turned off squid, etc. No changes. The ISP switched the office over to a better plan with a theoretical 6 Mbps up, still no change. At this point I tried testing the Macbook, and lo and behold there's the speed. But why? I have tried changing out everything, cables, switches, using another ethernet port on the G5, wiping the system, using DHCP, using manual IPs, changing DNS servers, etc. Nothing works. I figured that if there was something horribly wrong with the network, then internally I would find a similar issue, but that is perfect. iperf, ping, etc show no dropped packets and near saturation of the internal network. I'm at a loss as to what the heck is going on. Any ideas would be appreciated! Below are some screenshots of speedtest.net: G5: Macbook Air:

• ASA access lists and Egress Filtering

  - by Nate

  Hello. I'm trying to learn how to use a cisco ASA firewall, and I don't really know what I'm doing. I'm trying to set up some egress filtering, with the goal of allowing only the minimal amount of traffic out of the network, even if it originated from within the inside interface. In other words, I'm trying to set up dmz_in and inside_in ACLs as if the inside interface is not too trustworthy. I haven't fully grasped all the concepts yet, so I have a few issues. Assume that we're working with three interfaces: inside, outside, and DMZ. Let's say I have a server (X.Y.Z.1) that has to respond to PING, HTTP, SSH, FTP, MySQL, and SMTP. My ACL looks something like this: access-list outside_in extended permit icmp any host X.Y.Z.1 echo-reply access-list outside_in extended permit tcp any host X.Y.Z.1 eq www access-list outside_in extended permit tcp any host X.Y.Z.1 eq ssh access-list outside_in extended permit tcp any host X.Y.Z.1 eq ftp access-list outside_in extended permit tcp any host X.Y.Z.1 eq ftp-data established access-list outside_in extended permit tcp any host X.Y.Z.1 eq 3306 access-list outside_in extended permit tcp any host X.Y.Z.1 eq smtp and I apply it like this: access-group outside_in in interface outside My question is, what can I do for egress filtering? I want to only allow the minimal amount of traffic out. Do I just "reverse" the rules (i.e. the smtp rule becomes access-list inside_out extended permit tcp host X.Y.Z.1 any eq smtp ) and call it a day, or can I further cull my options? What can I safely block? Furthermore, when doing egress filtering, is it enough to apply "inverted" rules to the outside interface, or should I also look into making dmz_in and inside_in acls? I've heard the term "egress filtering" thrown around a lot, but I don't really know what I'm doing. Any pointers towards good resources and reading would also be helpful, most of the ones I've found presume that I know a lot more than I do.

• 412 Precodition Failed error only occurs on certain networks

  - by Andy

  One of my favorite websites: http://jessiejofficial.com (yes, I'm a Jessie J Fan :')) has recently started displaying the error message "412 Precondition Failed" whenever I visit it from my home network, even when I use Tor Browser. At first I thought that this was an issue with the whole website, however I have contacted the web developer and he has said that they has been plenty of hits within the last 48 hours. Plus, I discovered tonight that I can access the website from my phone, through the mobile network. So it appears to just be my network as all of the devices in my house connected to the WiFi display the same error when I try to visit any page of the site. However there have been no changes that we are aware of or are noticeable to our network since the website was accessible, and I have just heard that another person in a different part of the country is experiencing the same difficulties also. Any help/advice/suggestions would be appreciated greatly Update: When trying to ping 'jessiejofficial.com' in Windows command prompt the request times out on all four attempts, on any computer connected to the wireless network. I can now also confirm that the same thing occurs on my MacBook Pro.

• Thunderbird 15.0.1 cannot use Exchange 2003 SMTP

  - by speedreeder

  I'm having the strangest time getting a Thunderbird email client to connect to my Exchange 2003 server. I got the incoming IMAP account set up no problem, and I can receive mail. However sending mail will not work no matter what SMTP settings I enter. After checking the server, the proper settings should be port 25 with no authentication or connection security, which I have entered. I can ping the hostname of the server from the client machine in question. The Thunderbird error message I get is: "Sending of message failed. The message could not be sent because the connection to SMTP server -hostname omitted- was lost in the middle of the transaction." So I went to the server and double checked the settings for Exchange's SMTP stuff. I have it correct. I tried to telnet (on the server) to localhost 25. It appears to connect and then disconnect immediately, no message, no nothing. When I telnet to other ports (POP-110 for example) I get proper connection messages and a stable connection. There are no firewalls on either the client or the server. There's a firewall on the network but LAN-LAN traffic is unrestricted. I can reproduce the Thunderbird error on a second client, and I can't get any client to be able to telnet in. Anyone have any ideas?

• No outbound internet connection after restarting CentOS 6.3

  - by wnstnsmth

  After restarting a headless CentOS 6.3 machine, it lost outbound internet connectivity, i.e. I can still connect to the server via SSH (ssh root@**.126.18.56), but stuff such as ping google.com gives google.com: unknown host, and yum list some_package gives a lot of network errors. This is what ifconfig gives: eth0 Link encap:Ethernet HWaddr 00:25:90:78:2D:5D inet addr:**.126.18.56 Bcast:**.126.18.255 Mask:255.255.255.0 inet6 addr: fe80::225:90ff:fe78:2d5d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:75594 errors:0 dropped:0 overruns:0 frame:0 TX packets:787 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7074741 (6.7 MiB) TX bytes:144391 (141.0 KiB) Interrupt:20 Memory:f7a00000-f7a20000 eth1 Link encap:Ethernet HWaddr 00:25:90:78:2D:5C UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:16 Memory:f7900000-f7920000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:6 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:504 (504.0 b) TX bytes:504 (504.0 b) I have absolutely no clue how to debug this, and I find it very strange since I can still connect via ssh. EDIT: Weirdly, /etc/resolv.conf does not contain any entries, or none that I can make sense of: # Generated by NetworkManager search sui-inter.net # No nameservers found; try putting DNS servers into your # ifcfg files in /etc/sysconfig/network-scripts like so: # # DNS1=xxx.xxx.xxx.xxx # DNS2=xxx.xxx.xxx.xxx # DOMAIN=lab.foo.com bar.foo.com So is it possible that rebooting the server erased that file? It worked before at least! And how do I solve this? By the way, pinging an IP address works.

• Uploads fail with shorewall enabled

  - by JamesArmes

  I have an Ubuntu 8.04 server with shorewall 4.0.6 installed. When I try to upload files using FTP, SCP, or cURL the file upload stalls almost immediatly and eventually times out. If I turn off shorewall then the uploads work fine. I don't have any rules that specifically allow FTP and I'm not too concerned with it, but I do need to be able to upload via 22 (SCP) and 80 & 443 (cURL). This is what my rules look like: COMMENT Allow Server to respond to any web (80) and SSL (443) requests ACCEPT net $FW tcp 80 ACCEPT $FW net tcp 80 ACCEPT net $FW tcp 443 ACCEPT $FW net tcp 443 COMMENT Allow Server to respond to SNMPD (161) requests ACCEPT net $FW udp 161 COMMENT Allow Server to respond to MySQL (3306) requests (for MySQL Graphing) ACCEPT net $FW tcp 3306 COMMENT Allow Server to respond to any SSH connection attempts, and to SSH out.

• Active Directory server down, recovering without reinstalling

  - by whatever

  My Windows 2003 server suddenly ceased to function as a DC (this server is the only DC of the domain). All AD related services are down. The only way I can login to the AD is physically to the machine. Everytime I access an AD-related service (e.g. "AD users and computers") I get the below error: Naming information cannot be located because: The specified directory service attribute or value does not exist. Contact your system administrator to verify that your domain is properly configured and is currently online. I found the below system event which matches the time when the issue started, this re-occurs everytime I reboot the server. NTDS General | Global Catalog | Active Directory was unable to establish a connection with the global catalog. Additional Data Error value: 1355 The specified domain either does not exist or could not be contacted. Internal ID: 3200d33 I started the troubleshooting with DNS. Netdiag throws the below error although I think this is simply a consequence of not being able to access the Global Catalog. The procedure entry point DnsGetPrimaryDomainName_UTF8 could not be located in the dynamic link library DNSAPI.dll. Anyway DNS seems OK because I can ping the DC FQDN from the DC itself. I found the below solution which is supposed to help by doing some cleanup of the metadata: http://support.microsoft.com/kb/216498 If I follow procedure 1 here is what I get at step 9: no current site Domain - DC=<mydomain>,DC=<com> no current server no current naming context I can continue the procedure until step 14. I haven't tested step 15 as my understanding is that I will have to reinstall the whole AD again. Is there any way I can recover my AD from there without having to reinstall the whole thing? Update: Yes, the server was powered off/on because reboot would take forever (not because I thought power cycling the unit would fix it more than a reboot).

• Join Domain from VM

  - by Adis

  I have two VMs running on VMWare Player. I use NAT adapter settings. The host machine for VMs is running on corporate network. First VM has Domain controller running and I can log in on that machine using domain credentials. I named domain wm.local When I run IP config on this machine: IP: 192.168.87.132 Def Gataway: 192.168.87.2 DNS server: 192.168.87.2 DHCP server: 192.168.87.254 Second VM cannot join domain. When I try it with domain WM I'm propmted for credentials. And I enter Administrator credentials and than it waits for some time and I get response: "The specified domain either does not exist or could not be contacted" If i type wm.local as domain when trying to join it does not prompt me to login but just shows "An Active Directory Domain Controller (AD DC) for the domain wm.local could not be contacted. And here it takes no time to get this error message. Ipconfig on this machine: IP: 192.168.87.134 Def Gataway: 192.168.87.2 DNS server: 192.168.87.2 DHCP server: 192.168.87.254 I can ping second VM from first one. And I disabled firewalls on both machines. Any ideas? Is there any manual for this?

• OpenVZ container is running but does not show in vzlist nor can I find the private/conf files for the container

  I was creating a new OpenVZ container on one of our VPS Nodes while the power went out for that machine. After bringing the machine back online I could no longer access the container CTID=101. I could not destroy it using "vzctl destroy 101", I can not enter or control it, and "vzlist -a" does NOT display any containers at all (this was a fresh node and the first container was being created). I decided to create a new container at this point assuming that the old container just was not saved for some reason. However when I go to add the ip/host to the new container I get a warning that the IP is already in use. After doing a ping to the IP I realized there was a machine on that IP. I SSH into the machine and discover it is the OLD container that some how is orphaned. I can not find it on the filesystem, I can not find it using VZ commands, and It is set to start on Node boot so it is impossible to shutdown (even ssh in and typing the "shutdown now" command just reboots the container not shut it down). Is this a flaw in OpenVZ or am I missing something? I have all the outputs and logs if needed. Thank you all so much in advance.

• How to find out which process is hogging the linux server?

  - by user1149518

  We have a RHEL server. Today it suddenly became slow. Symptoms - It was responding slow to ping queries from other server. When I try to login using ssh, it was taking about 10 seconds to login. I was able to resolve the problem by doing some guess work. I killed one process which I thought was culprit. Which resolved the problem. Though I would like to know what's proper approach to detect the culprit in such kind of "slow server" situations. Le me know proper way to resolving such slowness issues and decting the process causing the slowness. These were the conditions when the server was slow - # vmstat 3 3 procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 1 1 176 6730868 285052 4899676 0 0 3 4 0 0 1 1 97 1 0 0 0 176 6751576 285064 4899704 0 0 0 115 15307 37171 1 1 96 3 0 0 0 176 6751948 285068 4899700 0 0 0 23 14813 39559 1 1 98 1 0 # top top - 16:38:18 up 150 days, 19:36, 64 users, load average: 1.68, 1.46, 1.44 Tasks: 1287 total, 2 running, 1284 sleeping, 1 stopped, 0 zombie Cpu(s): 1.3%us, 1.7%sy, 0.1%ni, 95.9%id, 0.7%wa, 0.0%hi, 0.2%si, 0.0%st Mem: 16620824k total, 9867124k used, 6753700k free, 287424k buffers Swap: 8193140k total, 176k used, 8192964k free, 4898996k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 26258 khk 34 19 130m 47m 7088 S 11.2 0.3 385:32.42 edm Though I would like to know what's proper approach to detect the culprit in such kind of "slow server" situations.

• Linux as a gateway (no NAT)

  - by Hugo

  I'm trying to configure a linux server as a gateway/router, but I can't get it to work, and all information I've managed to find is NAT-related. I have a public IP block for the gateway and devices behind it, so I want the gateway to simply route packets to the internet - again: no NATing! I've managed to get the gateway to access the internet successfully (that was just a matter of configuring the IP and GW), and the computers behind it can communicate with it. [EDIT: more info] This is actually an IPv6 block (2800:40:403::0/48) (but I've found that most utilities and instructions can be easily adapted from IPv4 to IPv6 with little hastle). The server has too ports: wan: 2800:40:403::1/48 lan: 2800:40:403::3/48 One of the computers behind it is connected to it via a switch; 2800:40:403::7/48 The wan interface on the server can ping6 www.google.com without issues. The lan interface on the server and the client can mutually ping each other without issues (as well as SSH, etc). I've tried setting the server as a default gateway for the client, with no luck: client # route -A inet6 add default gw 2800:40:403::3 dev eth1 server # cat /proc/sys/net/ipv6/conf/all/forwarding 1 I don't want any filtering/firewalling/etc, just plain routing. Thanks.

• Hyper-V VM's cannot access Host resources, and vice-versa

  - by Agent

  I have several Hyper-V vm's running on this Win2008 R2 Server box, and up until a reboot of the host server, all the VM's were able to access shared folders on the host. Now, they can't even ping the host server. From what I've seen, I need to setup an Internal only network through Virtual Network Manager in Hyper-V. I set this up, then tried to enable the Microsoft Virtual Network Switch Protocol option in this Internal Only NIC, but I get popups saying: Your current selection will also disable the following features: Microsoft virtual network switch protocol Which is absolutely stupid, considering the protocol is what I'm ticking the checkbox to Enable! As of now, on the host, I have 2 NICs: Physical - This NIC on the host machine does have the MVNS protocol enabled Virtual Network Adapter - Created through Hyper-V Virtual Network Manager as an External type of network. Trying to enable MVNS on this NIC also produces the error above. I've tried enabling Client for Microsoft Networks on the physical NIC for IPv6, but everytime I do that, all the VMs lose Internet connectivity and I cannot RDP into them. Anything else I can try?

• Internet compression proxy for low speed broadband?

  - by user23150

  I live in a rural location, using high-latency wireless off a local ISP's tower. My speed tests vary day to day, but I can get around 1Mb up/down. The problem is, I work with large files, uploading and downloading (HD videos, development software, etc.). It can be painful to wait sometimes. Plus I do some side contract game development, and it can be very difficult to playtest with other developers (200ms ping is a good day for me). Now, obviously it's not going to be easy to solve the latency problem without different wireless hardware. But speedwise, I am wondering if I can use some kind of compression technology on a proxy. For instance, my work computer has full access to a 26Mb down, 10Mb up connection, that is totally unused at night and the weekends. If I could run some kind of compression technology on our server, and use it as a proxy to route to my home computer, I could stand to gain some major speed. I realize that by bogging down a system with compression, I could potentially lose whatever speed gain I had. But the proxy server is a quad core xeon, and the receiving computer is a pretty decent i7 computer, so that shouldn't be a concern. I found http://toonel.net/ but it seems more geared toward very slow narrowband users, like dial-up. Plus, I would prefer to just be able to point my browser to a proxy server, rather then install software on my client machine. EDIT I thought about my question a little more, and realize I am going to need to install software on my client in order to decompress, and possible compress (for uploading). That's not a huge deal.

• Cisco ASA 5505 - InterVLAN NAT Exemptions Implementation not working

  - by Brandon Bearden

  Short version is we cannot communicate between our subnets. We have a Cisco ASA 5505 we are using for our network router. We have a Netgear L3 switch behind that with 10 vlans. Each VLAN is on its own subnet. (10.0.10.x/24, 10.0.11.x/24, etc) So ASA Switch Hosts We have PAT for each subnet to our outside interface. Each subnet NATs out properly. I have NAT exemption enabled for 2 of the subnets (eventually I will need all, but am just testing at the moment). Config is here: http://pastebin.com/pDsG7hsh I have tried multiple ways for the NAT exemption to allow all traffic from our inside VLANS. At this point in time I am trying to get "Engineering" to communicate with all hosts on "AuthUser". I can ping some hosts, but not as many as if I am directly on the interface. I can reach a port 80 service, but not 443. I cannot access anything via hostname or NetBIOS. What am I missing to allow higher security level interfaces to fully communicate with lower security level interfaces? Thx!

• Svchost.exe connecting to different IPs with remote port 445

  - by Coll911

  Im using Windows XP Professional SP2. Whenever I start my Windows, svchost.exe starts connecting to all the possible IPs on LAN like from 192.168.1.2 to 192.168.1.200. The local port ranges from 1000-1099 and the remote port being 445. After it's done with the local IPs, it starts connecting to other random IPs. I tried blocking connections to the port 445 using the local security polices but it didn't work. Is there any possible way I could prevent svchost from connecting to these IPs without involving any firewall installed? My PC slows down due to the load. I scanned my PC with MalwareBytes and found out it was infected with a worm, it's deleted now but still svchost is connecting to the IPs. I also found out that in my Windows Firewall settings, under Internet Control Message Protocol (ICMP), there's a tick on "allow incoming echo request" (usually disabled) which is locked and I can't disable it. Its description is as follows Messages sent to this computer will be repeated back to the sender. This is used for trouble shooting for e.g to ping a machine. Requests of this type are automatically allowed if TCP port 445 is enabled. Any solutions? I can't bear going with the reinstalling Windows phase again.

• Allow SFTP in iptables

  - by Kevin Orriss

  I have just purchased a VPS from linode and am going through the setup guide. I have everything running (apache2, php, mysql etc) but I am being denied access via SFTP when using fileZilla to upload a file. Now this is my second time installing the server as I missed a section out the first time. I was able to connect to my server through SFTP on filezilla the first time and the thing I missed out was adding a new user and editing the iptables in the firewall. So it would seem that the guide I have been following has blocked SFTP but allowed SSH. Here is the iptables file: *filter # Allow all loopback (lo0) traffic and drop all traffic to 127/8 that doesn't use lo0 -A INPUT -i lo -j ACCEPT -A INPUT ! -i lo -d 127.0.0.0/8 -j REJECT # Accept all established inbound connections -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # Allow all outbound traffic - you can modify this to only allow certain traffic -A OUTPUT -j ACCEPT # Allow HTTP and HTTPS connections from anywhere (the normal ports for websites and SSL). -A INPUT -p tcp --dport 80 -j ACCEPT -A INPUT -p tcp --dport 443 -j ACCEPT # Allow SSH connections # # The -dport number should be the same port number you set in sshd_config # -A INPUT -p tcp -m state --state NEW --dport 22 -j ACCEPT # Allow ping -A INPUT -p icmp -m icmp --icmp-type 8 -j ACCEPT # Log iptables denied calls -A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7 # Reject all other inbound - default deny unless explicitly allowed policy -A INPUT -j REJECT -A FORWARD -j REJECT COMMIT All I would like is a line I need to put in there which allows SFTP over port 22. Thank you for reading this.
