• iptables advanced routing

  - by Shamanu4

  I have a Centos server acting as a NAT in my network. This server has one external (later ext1) interface and three internal (later int1, int2 and int3). Egress traffic comes from users via int1 and after MASQUERADE goes via ext1. Ingress traffic comes from ext1, MASQUERADE, and goes via int2 or int3 according to static routes. | ext1 | x.x.x.x/24 +---------|----------------------+ | | | Centos server (NAT) | | | +---|------|---------------|-----+ | | | int1 | | int2 | int3 10.30.1.10/24 | | 10.30.2.10/24 | 10.30.3.10/24 ^ v v 10.30.1.1/24 | | 10.30.2.1/24 | 10.30.3.1/24 +---|------|---------------|-----+ | | | | | | | v v | | ^ -Traffic policer- | | |_____________ | | | | | +------------------|-------------+ | 192.168.0.1/16 | | Clients 192.168.0.0/16 The problem: Egress traffic seems to be dropped after PREROUTING table. Packet counters are not changing on MASQUERADE rule in POSTROUTING. If I change the routes to clients causing the traffic go back via int1 - everything works perfectly. current iptable configuration is very simple: # cat /etc/sysconfig/iptables *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -I INPUT 1 -i int1 -j ACCEPT -A FORWARD -j ACCEPT COMMIT *nat -A POSTROUTING -o ext1 -j MASQUERADE # COMMIT Can anyone point me what I'm missing? Thanks. UPDATE: 192.168.100.60 via 10.30.2.1 dev int2 proto zebra # routes to clients ... 192.168.100.61 via 10.30.3.1 dev int3 proto zebra # ...

• Openldap startup problems after upgrade

  - by Craig Efrein

  I am trying to syncrhonize a ldap slave and master server. The master server is using openldap 2.3.43-12 and the slave server is using openldap 2.4.23. I copied over the files in /var/lib/ldap, started the server and got this error: Oct 22 16:16:41 xe-ldap-slave1 slapd[12111]: bdb(dc=myserver,dc=fr): Program version 4.7 doesn't match environment version 4.4 Oct 22 16:16:41 xe-ldap-slave1 slapd[12111]: bdb_db_open: database "dc=myserver,dc=fr" cannot be opened, err -30971.

• Determine wifi capabilities of Windows box (with WSUS install rules)

  - by Hagen von Eitzen

  I need to determine if a computer is in fact a laptop with wifi capabilities (with emphasis on wifi rather than laptop). More precisely, I want to distribute a piece of software I wrote via WSUS and Local Update Publisher to those clients. To this end, I want to create appropriate "Package installable rules", that is simple rule used bay the Windows Update Service on the client to decide beforehand whether or not an update/installation package is applicable. Typically, such "installabel rules" are logical combinations of rules of type "File exists", "Registry Key exists", "WMI Query", "MSI Product Installed", so I'd prefer one of those methods. The method I hope someone here can help me find should work with Win 7/Vista, preferably also with XP. My guess is that WMI query is the way to go, but I have little experience in that. I have found that one can e.g. query for EnclosureType and that might detect a laptop. However, I would be much happier if an actually available wifi interface would be detected. Does anyone have an idea how to approach this? If there is anything you need me to clarify, don't hesitate to comment.

• Joining Samba to Active Directory with local user authentication

  - by Ansel Pol

  I apologise that this is somewhat incoherent, but hopefully someone will be able to make enough sense of this to understand what I'm trying to achieve and provide pointers. I have a machine with two network interfaces connected to two different networks (one of which it's providing several other services for, such as DNS), running two separate instances of Samba, one bound to each interface. One of the instances is just a workgroup-style setup using share-level authentication, which is all working fine. The problem is that I'm looking to join the other instance to an MS Active Directory domain (provided by MS Windows Small Business Server 2003) to enable a subset of the domain users to access the shares from Windows machines on the other network. The users who need access from the domain environment have accounts (whose names are all-lowercase versions of their domain usernames) on the machine running Samba, but I'm not sure about how to map the UIDs and everything I've read concerns authenticating accounts on that machine against either AD or another LDAP server. To clarify: I only want the credentials for AD users accessing the non-workgroup Samba instance to be authenticated against AD, not the accounts on the machine running Samba. I hope this is sufficiently clear. EDIT: In addition to being able to access the Samba shares from AD, I do also need to be able to access a share on the domain from the machine running Samba but would still like everything non-Samba-related to authenticate locally.

• Setting up port forwarding for web server

  - by reyjavikvi

  This could belong on Super User, but I thought this place was more appropiate. I want to run Apache in my computer and want to make it available to the outside world to test a couple things. Apparently, I have to go into my router's (a TP-LINK TD 8910G) settings and forward port 80 to my PC's IP. So far so good. Thing is, since the router uses a web based interface and it's kind of stupid, it told me that since I was using port 80 for this, I should access its settings through port 8080. Maybe it can't detect requests coming from the LAN, I don't know. Point is, now neither port can't access the configuration, and I can't access Internet. Specifically, trying to access anything (including 192.168.1.1, the router's settings) through port 80 turns up a blank page (maybe if I had the server running in my computer I'd get something, but I don't want to risk trying, I had to reset the router and restore the settings), and port 8080 gives a "Can't establish connection" error in Firefox (and similar ones in other browsers). Is there a way to configure the router to not redirect requests coming from inside the network? I'm a beginner with this stuff, so please try to explain in a simple way. If this is more appropiate in Super User, I'm sorry.

• Can't ping through default gateway

  - by Andrew G.H.

  I have the following configuration: Routing table on M3 is: Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 eth1 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.3.0 0.0.0.0 255.255.255.192 U 0 0 0 eth0 Routing table on M1 is: Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 So basically M3's gateway is M1, and M1's gateway is M2's wireless internet interface. If I ping 8.8.8.8 from M1, everything is ok, replies are received. Pinging from M1 to M3 and viceversa is also possible. I have configured M1 as gateway trafic forwarder using firestarter package and stopped firewall with it. iptables policies are ACCEPT for everything. Problem: I have tried ping-ing ip 8.8.8.8 from M3 but without success. What could be the source of this problem?

• Port Forwarding failing only to Ubuntu servers from Draytek router

  - by Rufinus

  I know this is a kinda unusal question, but Draytek support (..which is very eager to solve the issue) seems to reach its limits. Scenario: Draytek Vigor Multiwan router with current firmware. Multiple WAN IP Aliases on one of the wan ports DMZ (or port forwarding doesnt matter) from wan ip alias to internal host currently i have two internal hosts: 192.168.0.51 (Ubuntu) 192.168.0.53 (Debian) both should be accessible from outside via one of the wan ip aliases. both are accessible with their internal ip's at all times (!) If the router gots restartet, both external ips are forwarding to its internal hosts. But after a few minutes up to 2 hours, the ubuntu host is no longer reachable via its external interface. The debian hosts on the other hand is reachable. In what does ubuntu differs from debian ? I know at least of one user with the exact same problem. see http://ubuntuforums.org/showthread.php?p=10994279 Any ideas ? TIA EDIT: via ping diagnostics directly on vigor, 192.168.0.53 is pingable, 192.168.0.51 is not. but both hosts are perfectly reachable from anywhere inside the network. if i restart ubuntu networking it works again for a short time.... i'm out of ideas.. EDIT 2: after further investigation, i noticed a ping from .51 to the network (or a host in the internet) is enough to make the port-forwarding working again. So i will add an Cronjob as a "keep-alive" ping. This will solve the problem, but the reason for this behaivor is still in the dark. Thanks to all commentors.

• Arch Linux drops me on my school network

  - by Kravlin

  I'm running a Lenovo X61 which i carry around my college for getting on the internet at various points in the day. The network has always been finicky but recently it's gotten worse. I'll connect using iwconfig, get an ip from dhcpcd and log in using vpnc to their system. Sometimes I'll stay connected for hours but most of the time within 30 seconds my network traffic will drop to zero and i'll be unable to do anything. My computer still belives it's connected, however to try again i need to put my wireless interface down, put it back up and try again. It's gotten so bad that i've got a window on my computer pinging yahoo or google constantly in order to know if i'm still able to get online. I know other people who have used Arch Linux that don't have the same problems as well as people who use Ubuntu who haven't had any problems either. It seems like my computer is a special case. Does anyone have any suggestions on how to fix it? dmesg doesn't show anything out of the ordinary going on and i don't know where else to look for errors or other things to try. Edit: this doesn't happen on my home network. It's a problem that only happens at school.

• Cannot connect to windows server by name over vpn connection

  - by ErocM

  I have a rented dedicated windows server on a public ip that is acting as a SQL Server and VPN server. I need to connect to this server via computer name to get replication in place. I cannot use an ip address due to this issue: So, due to this, we are going the VPN route. That is my primary issue: After I am connected to this server's vpn, I can connect to SQL Server using the ip address but I cannot connect by the computer's name as you can see below... Right now, there is no hardware firewall on it since I had it removed to test this issue. I am running Windows 2008 Enterprise Server as the VPN server. I am not sure if the route print will help any from the workstation trying to connect but here is the info: IPv4 Route Table Active Routes: Network Destination Netmask Gateway Interface Metric 10.0.0.0 255.0.0.0 10.0.0.1 10.0.0.2 21 10.0.0.2 255.255.255.255 On-link 10.0.0.2 276 Any other info needed?

• IPv6 - Public IPs, private IPs, IPs derived from the MAC address? Confused!

  - by sinni800

  I'm pretty much excited for IPv6 because of the large address room and (potential?) owning of more than one IP, or even tens of IPs (/122 subnet?) Though one magazine has now confused me. In a current issue (no. 3) of "CT", a German computer magazine, I read that when using IPv6 your IP address consists of your MAC address and various other things, and that this address will be public on the web, no matter what access point / LAN you connect to. My knowledge of IP(v6) is in contrary of this. I thought you will normally always have a a local network IP and NAT takes care of your Internet access, and your provider gives the NAT router an IP. I've heard of the 6to4 interface, but does this one give you your own ip in the IPv6 net? Personally I hope it still is through a personal IP space (like 192.168, 127.16-31, 10. in IPv4) in private networks with a NAT going to the Internet. And also I hope that providers will offer subnets to private customers so they don't have to use NAT anymore. Yay for converting your LAN into the WAN and using better security (so Computers from the same subnet still get access rights like normal).

• IPSec Tunnel to Amazon EC2 - Netkey, NAT, and routing issue

  - by Ernest Mueller

  I'm working on getting an IPSec VPN working between Amazon EC2 and my on-premise. The goal is to be able to safely administer stuff, up/download data, etc. over that tunnel. I have gotten the tunnel up in openswan between a Fedora 12 instance with an elastic IP and a Cisco router that's also NATted. I think the ipsec part is OK, but I'm having trouble figuring out how to route traffic that way; there's no "ipsec0" virutal interface because on Amazon you have to use netkey and not KLIPS for the vpn. I hear iptables may be required and I'm an iptables noob. On the left (Amazon), I have a 10. network. Box 1 is privately 10.254.110.A, publically IP 184.73.168.B. Netkey tunnel is up. Box 2 is publically 130.164.26.C, privately 130.164.0.D And my .conf is: conn ni type= tunnel authby= secret left= 10.254.110.A leftid= 184.73.168.B leftnexthop= %defaultroute leftsubnet= 10.254.0.0/32 right= 130.164.26.C rightid= 130.164.0.D rightnexthop= %defaultroute rightsubnet= 130.164.0.0/18 keyexchange= ike pfs= no auto= start keyingtries= 3 disablearrivalcheck=no ikelifetime= 240m auth= esp compress= no keylife= 60m forceencaps= yes esp= 3des-md5 I added a route to box 1 (130.164.0.0/18 via 10.254.110.A dev eth0) but that doesn't do it for predictable reasons, when I traceroute the traffic's still going "around" and not through the vpn. Routing table: 10.254.110.0/23 dev eth0 proto kernel scope link src 10.254.110.A 130.164.0.0/18 via 10.254.110.178 dev eth0 src 10.254.110.A 169.254.0.0/16 dev eth0 scope link metric 1002 Anyone know how to do the routing with a netkey ipsec tunnel where both sides are NATted? Thanks...

• Preferred mail system/server for a company?

  - by Trevoke

  Say you are responsible for setting up an email solution at a company. Which would be your choice? I know of the following options, but many of them not well: Gordano Mail System Exchange Exim Postfix Qmail Zimbra For having used it a little over two years, I really, really like Gordano Mail System. They offer a whole bunch of things, like calendaring, anti-spam, anti-virus, extremely complete and filterable logging options, aliases, a customizable webmail interface... And their software can be installed on both a Windows or Linux OS. In addition, their support is top-notch, their knowledgebase comprehensive (and, I will admit with a touch of pride, I have contributed, with my questions, to the addition of a few articles in there). Of course, they're not free, which can be a problem, but they're not Exchange, and they do offer pretty much everything that Exchange offers -- which is great if you want to stay away from that, but need all the features. Although, if you need a Blackberry Exchange Server, or something similar, I'm not sure what you should go for. So.. What would your choice be? Why? I've never played with a more DIY email solution, but I'm sure many people here have and wouldn't trade their setup for the world :)

• DVD drive won't work after installing software

  - by Dan

  DVD drive was already region-free but for some reason would not play a certain DVD as it was the "wrong region". This is the first time I've played a DVD on the drive, but I've imported a lot of CDs before and they always worked fine, even CDs bought from the USA (I live in the UK). To get around this, I downloaded a piece of software called "DVD Region Killer". (Clicking the link won't start the download, so go ahead and check it.) After this, the drive isn't recognised. It won't show up in "My Computer", and when I insert a disc it will start to whir but not take action, i.e. iTunes won't recognise that I have put a CD in. In the Device Manager, the drive shows up with a caution-sign. The device status reads: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Disabling, uninstalling and reinstalling does not help. Clearly the software download is the issue, but it is difficult to remove. The only files I can find in Program Files are: C:\Program Files (x86)\Elaborate Bytes\DVD Region Killer which contains a changelog and a HTML document which has no info on uninstalling. It doesn't show up on "Add or Remove Programs", or even as a background process when I press ctrl-alt-del. Apparently it has no interface as such, and can be accessed by an icon in the system tray, (see review in link) but I don't see the icon. If it helps to know, I have a Dell Inspiron running Windows 8 64-bit, and the model of the DVD drive is: MATSHITA DVD+-RW UJ8C2 Thanks in advance.

• Windows 2012 RDS Temporary profile for Administrator

  - by Fabio

  I've configured a Windows 2012 RDS Farm with two virtual servers (VMWare - each one on a different ESX server). Both servers have Licensing, Web Access, Gateway, Connection Broker and Session Host roles. High Availability is set up and it works fine. Remote Apps are working and even Windows XP clients have access to the web interface. User profile path is \vmfiles1\UserProfileDisks\App\ and almost everyone has full right access to it. The problem I have is that I would like to be able to access both servers at the same time with the Administrator account (console), but each time I try, the second server that I logon to give me access with a temporary profile. I tried to enable/disable multiple sessions per user and forced Admin logoff with the GPO but nothing changed. Another thing is that the server pool is not saved, so each time I restart the RDS server or I logoff from it, I have to add a server in the server manager. Do you have any idea? Sorry if my english is not perfect.

• Comprehensive solution for managing patches, event viewing, change management, inventory, etc

  - by Holocryptic

  I'm looking for a solution that incorporates most or all of the following: Patch Management, Server event viewing/tracking, AD change management, ticketing and internal/external kb, remote access - ability to shadow user sessions or create new ones, imaging, and inventory. Our environments contains Windows Servers and ESXi Hosts (We're not completely virtual, but we're moving that direction). Various Cisco and Linksys switches and firewalls. This is a tall order, and I don't know if it can be done on a reasonable budget. I've looked and found some questions on SF that deal with some of this: http://serverfault.com/questions/72015/active-directory-management-tools-for-medium-sized-forest-less-than-1000-users http://serverfault.com/questions/4021/are-there-any-tools-to-do-change-management-with-active-directory-group-policy http://serverfault.com/questions/21752/what-is-a-good-patch-update-management-server What I'm ideally looking for is a reasonably cheap solution that integrates the features into a central interface. We're a non-profit, so money is a limiting factor (the cheaper, the better; but we have a max of $15k). What we are trying to avoid is having to deal with multiple vendors, while maintaining scalability (we're creating more sites that we'll have to manage). Is this possible, or will we have to cobble together something to make it work for us?

• Blink build with Xcode failed

  I found a GPL-ed SIP client for Mac, Blink. I'd like to build it from source since the binaries are only available as paid download. Just FYI i'm studying programming at university but have no experience in building complex application from source. After downloading the content of the repository i opened the Xcode project and tried to build on OS X 10.7, Xcode 4.2.1. Unfortunately the build fail with 1 error and many warnings Most of the warnings are like this: Attribute Unavailable: Custom Identifiers in Interface Builder versions prior to 3.2 The error message is: Apple Mach-O Linker (ld) Error Command /Developer/usr/bin/clang failed with exit code 1 preceded by the warning Apple Mach-O Linker (ld) Warning directory not found for option '-L/Users/Sergio/Downloads/Blink/devel.ag-projects.com/repositories/public/blink-cocoa/Distribution/Frameworks' I notice that in the list of required files i have this files missing: Dependencies/Frameworks libgcrypt.11.6.0.dylib libgcrypt.11.dylib libgnutls-extra.26.dylib libgnutls.26.dylib libgpg-error.0.dylib libintl.8.dylib liblzo.1.dylib libtasn1.3.dylib Dependencies/Resources lib Frameworks/Linked Frameworks Sparkle.framework Products Blink.app It should be possible to download these files somewhere.

• Change the order of IP addresses returned by ifconfig?

  - by erikcw

  I have an Ubuntu server with several IP addresses attached to it. 127.0.0.1 is listed as venet0 by ifconfig. I'm using Chef to configure the server. The problem is that chef is listing 127.0.0.1 as the IP address for the server instead of one of the server's "real" IPs. (apparent "ohai ipaddress" uses the first IP listed by ifconfig to determine the server's IP). How can I change the order so the servers main IP is listed first instead of the 127.0.0.1? Can venet0 be deleted and venet0:0 be "promoted" to take its place since 127.0.0.1 is already listed in the "lo" interface? 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:334 errors:0 dropped:0 overruns:0 frame:0 TX packets:334 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:16700 (16.7 KB) TX bytes:16700 (16.7 KB) venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:127.0.0.1 P-t-P:127.0.0.1 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 RX packets:7622207 errors:0 dropped:0 overruns:0 frame:0 TX packets:8183436 errors:0 dropped:1 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2102750761 (2.1 GB) TX bytes:2795213667 (2.7 GB) venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:XXX.XXX.XXX.XX1 P-t-P:XXX.XXX.XXX.XX1 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 venet0:1 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:XXX.XXX.XXX.XX2 P-t-P:XXX.XXX.XXX.XX2 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 route -n route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.0.2.1 0.0.0.0 255.255.255.255 UH 0 0 0 venet0 0.0.0.0 192.0.2.1 0.0.0.0 UG 0 0 0 venet0

• I/O Error on LG GSA-H12N DVD drive on Windows 7

  - by Ashwin

  I am facing an I/O Error when I try to burn DVD data discs on my LG GSA-H12N DVD drive on Windows 7. Note that I was able to do this same operation on the same hardware/software just a day earlier without any problems, but with Windows XP. The only change (AFAIK) has been the installation of Windows 7 to replace Windows XP on this PC. Here is the error I get when I try to burn a DVD data disc using CDBurnerXP 4.2.7.1801: Burning error occured An error occured while burning the disc. Most likely the disc is not usable. Usually these errors happen if the inserted media is not compatible to the drive or of poor quality. (devNTSPTI_IO_Error) Could not write to Disc (LBA: 52864 Length: 32). SCSI Pass-through Interface I/O Error. - 0xFF045D Note that there can be no problem with the discs since I have been using the same discs (from the same box) just before the Windows 7 installation with no problems. The only change has been Windows 7. I tried InfraRecorder v0.5 and ImgBurn v2.5 and got similar I/O errors: Note that Windows 7 lists the LG GSA-H21N drive as being compatible (see this link). I also checked the LG Drivers website and using the firware update from there updated the drive firmware from version UL01 to UL02. But, even this has not helped. The drive reads DVDs without any problem, but continues to produce coasters. Could someone help me figure out what is the problem? Thanks :)

• How to make a static route when using two internet connections?

  - by webmasters

  I have asked a question here on how to choose which applications will use a 3G internet connection and which applications will use the LAN. User harrymc gave a very complete and interesting answer, pointing that this is possible using static routes for certain websites. Now, lets say I want to access google.com only through my 3G internet connection. How would that static root look like? google has the IP: 173.194.39.180 here is a print of my route table, the 3G Modem has the IP: 10.81.132.96 +-----------------------------------------------------------------------------+ ¦ IPv4 Route Table ¦ ¦ =========================================================================== ¦ ¦ Active Routes: ¦ ¦ Network Destination Netmask Gateway Interface Metric ¦ ¦ 0.0.0.0 0.0.0.0 192.168.2.1 192.168.2.102 20 ¦ ¦ 0.0.0.0 0.0.0.0 10.81.132.97 10.81.132.111 286 ¦ ¦ 10.81.132.96 255.255.255.224 On-link 10.81.132.111 286 ¦ ¦ 10.81.132.111 255.255.255.255 On-link 10.81.132.111 286 ¦ ¦ 10.81.132.127 255.255.255.255 On-link 10.81.132.111 286 ¦ ¦ 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 ¦ ¦ 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 ¦ ¦ 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 ¦ ¦ 192.168.2.0 255.255.255.0 On-link 192.168.2.102 276 ¦ ¦ 192.168.2.102 255.255.255.255 On-link 192.168.2.102 276 ¦ ¦ 192.168.2.255 255.255.255.255 On-link 192.168.2.102 276 ¦ ¦ 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 ¦ ¦ 224.0.0.0 240.0.0.0 On-link 192.168.2.102 276 ¦ ¦ 224.0.0.0 240.0.0.0 On-link 10.81.132.111 286 ¦ ¦ 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 ¦ ¦ 255.255.255.255 255.255.255.255 On-link 192.168.2.102 276 ¦ ¦ 255.255.255.255 255.255.255.255 On-link 10.81.132.111 286 ¦ +-----------------------------------------------------------------------------+

• Solaris 10 invalid ARP requests from 0.0.0.0? Link up/down every hour or 2

  - by JWD

  The guys at the data center where I'm hosting a server running Solaris 10 are telling me that my server is making a lot of invalid arp requests. This is an example of a portion of what was sent to me from the logs (with Mac addresses and IP addresses changed). [mymacaddress]/0.0.0.0/0000.0000.0000/[myipaddress]/[Datestamp]) It's being logged every hour. I don't see anything in the arp tables (arp -a) or routing tables (netstat -r) and I don't see anything relating to 0.0.0.0 when snoping the arp requests. The only place I see any reference to 0.0.0.0 is if I do netstat -a for the SCTP SCTP: Local Address Remote Address Swind Send-Q Rwind Recv-Q StrsI/O State ------------------------------- ------------------------------- ------ ------ ------ ------ ------- ----------- 0.0.0.0 0.0.0.0 0 0 102400 0 32/32 CLOSED But not really sure what that means. Doesn't seem like I can disable SCTP. There are some tunable SCTP parameters but it's not something I'm familiar with. Do I have to add changes to /etc/system? Looks like sctp_heartbeat_interval might be what I need to change? If it makes any difference, I have a few solaris zones running on this server, each with their own IP address on a virtual interface. eth0:0, eth0:1, etc. Does anyone have any idea what might be causing this and how to stop it? I think the switch I'm connected to doesn't like it and momentarily drops the connection. Is there anyway to at least block those requests using ipfilter or something else? Update: This was happening more frequently but now it seems to be happening roughly every hour or every two hours. It's not consistent. I tried setting setting the link speed and duplex to match the switch port and that seemed to make it stop happening for a few hours but then it started again.

• Issue with multiple bridging for KVM hosts

  - by Henry-Nicolas Tourneur

  I'm using KVM and libvirt on my host (Debian lenny) + 2 bridges per guest (one for mgmt, one for public traffic). That setup isn't stable at all, sometimes I can do pings to a management ip, sometimes not. I don't know if my bridging paramateres are correct, could you check ? or if there is anything wrong ... Please also note that interface on guest doesn't flap and that I got not logs on my host. Of course forwarding is enabled. iface eth3 inet manual auto bond0 iface bond0 inet manual slaves eth1 eth2 pre-up ip link set bond0 up down ip link set bond0 down auto br0 iface br0 inet static address 10.160.0.7 netmask 255.255.255.128 bridge_ports eth3 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off auto br0:1 iface br0:1 inet static address 10.160.0.9 netmask 255.255.255.128 auto br0:2 iface br0:2 inet static address 10.160.0.10 netmask 255.255.255.128 auto br1 iface br1 inet static address 217.4.40.242 netmask 255.255.255.240 gateway 217.4.40.241 pre-up /etc/network/firewall start bridge_ports bond0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off auto br1:1 iface br1:1 inet static address 217.4.40.252 netmask 255.255.255.240 auto br1:2 iface br1:2 inet static address 217.4.40.253 netmask 255.255.255.240

• Same netmask or /32 for secondary IP on Linux

  - by derobert

  There appear to be (at least) two ways to add a secondary IP address to an interface on Linux. By secondary, I mean that it'll accept traffic to the IP address, and responses to connections made to that IP will use it as a source, but any traffic the box originates (e.g., an outgoing TCP connection) will not use the secondary address. Both ways start with adding the primary address, e.g., ip addr add 172.16.8.10/24 dev lan. Then I can add the secondary address with either a netmask of /24 (matching the primary) or /32. If I add it with a /24, it gets flagged secondary, so will not be used as the source of outgoing packets, but that leaves a risk of the two addresses being added in the wrong order by mistake. If I add it with /32, wrong order can't happen, but it doesn't get flagged as secondary, and I'm not sure what the bad effects of that may be. So, I'm wondering, which approach is least likely to break? (If it matters, the main service on this machine is MySQL, but it also runs NFSv3. I'm adding a second machine as a warm standby, and hope to switch between them by changing which owns the secondary IP.)

• Problem routing between directly connected Subnets w/ ASA-5510

  - by Zephyr Pellerin

  This is an issue I've been struggling with for quite some time, with a seemingly simple answer (Aren't all IT problems?). And that is the problem of passing traffic between two directly connected subnets with an ASA While I'm aware that best practice is to have Internet - Firewall - Router, in many cases this isn't possible. For example, In have an ASA with two interfaces, named OutsideNetwork (10.19.200.3/24) and InternalNetwork (10.19.4.254/24). You'd expect Outside to be able to get to, say, 10.19.4.1, or at LEAST 10.19.4.254, but pinging the interface gives only bad news. Result of the command: "ping OutsideNetwork 10.19.4.254" Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.19.4.254, timeout is 2 seconds: ????? Success rate is 0 percent (0/5) Naturally, you'd assume that you could add a static route, to no avail. [ERROR] route Outsidenetwork 10.19.4.0 255.255.255.0 10.19.4.254 1 Cannot add route, connected route exists At this point, you might gander if its a NAT or Access list problem. access-list Outsidenetwork_access_in extended permit ip any any access-list Internalnetwork_access_in extended permit ip any any There is no dynamic nat (or static nat for that matter), and Unnatted traffic is permitted. When I try pinging the above address (10.19.4.254 from Outsidenetwork), I get this error message from level 0 logging (debugging). Routing failed to locate next hop for icmp from NP Identity Ifc:10.19.200.3/0 to Outsidenetwork:10.19.4.1/0 This led me to set same-security traffic permit, and assigned the same, lesser and greater security numbers between the two interfaces. Am I overlooking something obvious? Is there a command to set static routes that are classified higher than connected routes?

• Internet explorer rejects cookies in kerberos protected intranet sites

  - by remix_tj

  I'm trying to build an intranet site using joomla. The webserver is using HTTP Kerberos authentication with mod_kerb_auth. Everything works fine, the users get authenticated and so on. But if i try to login to the administrator panel i can't because IE does not accept the needed cookies. No such problem with firefox. The intranet site is called "intranet_new" and is hosted by webintranet04, under the directory /var/www/vhosts/joomla/intranet_new/. I have my virtualhost for intranet_new containing this: <Location /> AuthType Kerberos AuthName "Kerberos Login" KrbMethodNegotiate On KrbMethodK5Passwd On KrbAuthRealms PROV.TV.LOCAL Krb5KeyTab /etc/apache2/HTTP.keytab require valid-user </Location> The same is for webintranet04 virtualhost, which is the default pointing to /var/www and contains: <Location /vhosts/joomla/> AuthType Kerberos AuthName "Kerberos Login" KrbMethodNegotiate On KrbMethodK5Passwd On KrbAuthRealms PROV.TV.LOCAL Krb5KeyTab /etc/apache2/HTTP.keytab require valid-user </Location> the very strange problem i have is that if i open http:// webintranet04/vhosts/joomla/intranet_new/administrator IE allows me to login, accepting cookie. If i open http:// intranet_new/administrator, instead, i loop on the login page. Last, intranet_new is a CNAME record of webintranet04. This is only an IE problem. I need: - the admin interface to work with IE - the "kerberized" zone to accept cookie, because i am deploying other programs requiring cookies.

• 10 GigE interfaces limits single connection throughput to 1 Gb on a ProCurve 4208vl

  - by wazoox

  The setup is as follow : 3 Linux servers with Intel CX4 10 GigE controllers and an X-Serve with a Myricom 10 GigE CX4 controller are connected to a ProCurve 4208vl switch, with a myriad of other machines connected through good ol' 1000 base-T. The interfaces are actually set up as 10 Gig, according to both the switch monitoring interface and the servers (ethtool, etc). However a single connection between two 10 GigE equipped machines through the switch is limited to exactly 1Gb. If I connect two of the 10 GigE machines directly with a CX4 cable, netperf reports the link bandwidth as 9000 Mb/s. NFS achieves about 550 MB/s transfers. But when I'm using the switch, the connection tops at 950 Mb/s through netperf and 110 MB/s with NFS. When I open several connections from 3 of the machines to the 4th, I get 350 MB/s of NFS transfer speed. So each individual 10 GigE ports actually can reach much more than 1 Gb, but individual connections are strictly limited to 1 Gb. Conclusion : the 10 GigE connection through the switch behaves exactly like a trunk of 10 1 Gb connections. That doesn't make any sense to me, unless HP planned these ports only for cascading switches or strictly for many-clients-to-single-server connection. Unfortunately this is NOT the envisioned setup, we need big throughput from machine to machine. Is this a not-so-known (or carefully hidden...) limitation of this type of switch? Should I suggest seppuku to the HP representative? Does anyone have any idea on how to enable a proper behaviour ? I upgraded for an hefty price from bonded 1Gb links to 10 GigE and see exactly ZERO gain! That's absolutely unacceptable.
