• DNS requests failing from computers that can ping DNS server

  - by dunxd

  I have a situation where computers in some of our remote offices from time to time lose the ability to use our DNS server (in head office) to resolve hostnames. The offices are connected via VPN using Cisco ASA 5505 (VPNclient config rather than Site to Site). Ping to the IP address of the DNS server works. But nslookup will get a "no response from server" message. Computers in other locations can use DNS fine. This is an intermittent problem. One day/hour it works, another it doesn't. Other offices connected in the same way work when another doesn't. No config changes have been made on routers around the time we see the problem. Some users have reported that the problem goes away after doing a repair connection in Windows XP. I think this could be caused by the DNS cache being flushed as part of this - the Windows DNS cache makes the intermittent problem look less so because it caches failed lookups as well as successful ones. However, it is possible some other aspect of Windows is involved. Windows 7 clients have also had the same problem. Any pointers on deeper troubleshooting, or anyone else found this?

• Persistent routes for DD-WRT PPTP VPN client

  - by Tim Kemp

  My home network in the USA is behind a Buffalo router (G300NH) running their version of DD-WRT. I use the built-in PPTP VPN client to connect to a VPN provider in the UK. I route certain traffic over the VPN (so it has a UK source address, for various entirely legal reasons) which I achieved by following the instructions in the DD-WRT docs and my VPN provider's own instructions. I placed two commands like this in the firewall script: route add -net xxx.xxx.0.0 netmask 255.255.0.0 dev ppp0 route add -net yyy.yyy.0.0 netmask 255.255.0.0 dev ppp0 I didn't put any of the iptables rules in since it my setup doesn't seem to need them. It works like a charm. Traffic to the xxx subnets goes over the VPN, everything else goes out over my ISPs own pipes. The problem comes when the VPN drops, which it does occasionally. DD-WRT does a fine job of reconnecting it automatically, but the routes are trashed every time that happens. How do I automate the process of re-establishing my routes? I thought about static routes, but the IP address of the VPN connection is dynamically assigned (which is why I'm using dev ppp0). Many thanks, Tim

• Accessing Virtual Host from outside LAN

  - by Ray

  I'm setting up a web development platform that makes things as easy as possible to write and test all code on my local machine, and sync this with my web server. I setup several virtual hosts so that I can access my projects by typing in "project" instead of "localhost/project" as the URL. I also want to set this up so that I can access my projects from any network. I signed up for a DYNDNS URL that points to my computer's IP address. This worked great from anywhere before I setup the virtual hosts. Now when I try to access my projects by typing in my DYNDNS URL, I get the 403 Forbidden Error message, "You don't have permission to access / on this server." To setup my virtual hosts, I edited two files - hosts in the system32/drivers/etc folder, and httpd-vhosts.conf in the Apache folder of my WAMP installation. In the hosts file, I simply added the server name to associate with 127.0.0.1. I added the following to the http-vhosts.conf file: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot "c:/wamp/www/ladybug" ServerName ladybug ErrorLog "logs/your_own-error.log" CustomLog "logs/your_own-access.log" common </VirtualHost> <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot "c:/wamp/www" ServerName localhost ErrorLog "logs/localhost-error.log" CustomLog "logs/localhost-access.log" common </VirtualHost> Any idea why I can't access my projects from typing in my DYNDNS URL? Also, is it possible to setup virtual hosts so that when I type in http://projects from a random computer outside of my network, I access url.dyndns.info/projects (a.k.a. my WAMP projects on my home computer)? Help is much appreciated, thanks!

• Specific DNS sometimes resolves to wildcard, incorrectly

  - by Mojo

  I have an intermittent problem, and I'm not sure where to start trying to troubleshoot it. In our dev environment, we have two visible IP addresses on load balancers, one to the front-end, and one to a number of back-end service machines. The front-end is configured to take a wildcard DNS name to support generic "portals." dev.example.com A 10.1.1.1 *.dev.example.com CNAME dev.example.com The back-end servers are all specific names within the same space: core.dev.example.com A 10.1.1.2 cms.dev.example.com CNAME core.dev.example.com search.dev.example.com CNAME core.dev.example.com Here's the problem. Periodically a developer or a program trying to reach, say, cms.dev.example.com will get a result that points to the front-end, instead of the back-end load balancer: cms.dev.example.com is an alias to core.dev.example.com core.dev.example.com is an alias to dev.example.com (WRONG!) dev.example.com 10.1.1.1 The developers are all on Mac OS X machines, though I've seen the problem occur on an Ubuntu machine as well, using a local cloud host DNS resolver. Sometimes the developer is using a VPN, which directs the DNS to its own resolver, and sometimes he's on the local net using a DNS resolver assigned by the NAT router. Sometimes clearing the Mac OS X DNS cache, logging into the VPN, then logging out of the VPN, will make the problem go away. The origin authoritative server is on zerigo, and a dig directly to their name servers always seems to give the correct answer. The published DNS cache time for these records is 15 minutes, but the problem has been intermittent for about a week. Any troubleshooting suggestions?

• Managing an application across multiple servers, or PXE vs cfEngine/Chef/Puppet

  - by matt

  We have an application that is running on a few (5 or so and will grow) boxes. The hardware is identical in all the machines, and ideally the software would be as well. I have been managing them by hand up until now, and don't want to anymore (static ip addresses, disabling all necessary services, installing required packages...) . Can anyone balance the pros and cons of the following options, or suggest something more intelligent? 1: Individually install centos on all the boxes and manage the configs with chef/cfengine/puppet. This would be good, as I have wanted an excuse to learn to use one of applications, but I don't know if this is actually the best solution. 2: Make one box perfect and image it. Serve the image over PXE and whenever I want to make modifications, I can just reboot the boxes from a new image. How do cluster guys normally handle things like having mac addresses in the /etc/sysconfig/network-scripts/ifcfg* files? We use infiniband as well, and it also refuses to start if the hwaddr is wrong. Can these be correctly generated at boot? I'm leaning towards the PXE solution, but I think monitoring with munin or nagios will be a little more complicated with this. Anyone have experience with this type of problem? All the servers have SSDs in them and are fast and powerful. Thanks, matt.

• Vista laptop 1 connects to network but Vista laptop 2 doesn't

  - by Jaips

  (Sorry if this is a dulipcate. I did a hunt but couldn't find matching question) We recently got a new router for our network (thomson TG585v8). It was already pre-configured by the ISP and was easy to setup. Both Vista laptops in this home network connected without trouble as well a iPod touch, all via wifi. In the last two days one of the laptops has been unable to connect cleanly to the network (connects as unidentified network). The other laptop, and iPod have not had any issues. I can't think of anything that has changed to make this happen now. I have rebooted the laptop and the router. I have updated the laptop wireless driver I have checked the laptop is set to automatically get IP I have logged into the router which correctly identifies all three wireless devices. The problem laptop connects via LAN without issue. Some things that may or may not matter: The problem laptop also sometimes uses a 3G dongle Both laptops use Windows Live Mesh to sync folders Laptop is usually set to go to sleep NB: it seems this is an intermittent issue, after an hour (since i noticed it) it seems to have fixed itself. Would love ideas though to solve this problem for good.

• OpenVPN with MacOS X Client and same subnets in local and remote net.

  - by Daniel

  I have a homenetwork 192.168.1.0/24 with gteway 192.168.1.1 and a remote network with the same parameters. Now I want to create a OpenVPN tunnel between those networks. I have no problems with Windows, because Windows routes everything to 192.168.1.0/24 except 192.168.1.1 throught the tunnel. On MacOS X however I see the folling line in the Details window: 2010-05-10 09:13:01 WARNING: potential route subnet conflict between local LAN [192.168.1.0/255.255.255.0] and remote VPN [192.168.1.0/255.255.255.0] When I list the routes I get the following: Internet: Destination Gateway Flags Refs Use Netif Expire default 192.168.1.1 UGSc 13 3 en1 127 localhost UCS 0 0 lo0 localhost localhost UH 12 3589 lo0 169.254 link#5 UCS 0 0 en1 192.168.1 link#5 UCS 1 0 en1 192.168.1.1 0:1e:e5:f4:ec:7f UHLW 13 17 en1 1103 192.168.1.101 localhost UHS 0 0 lo0 192.168.6 192.168.6.5 UGSc 0 0 tun0 192.168.6.5 192.168.6.6 UH 1 0 tun0 My Interfaces are en1 - My local Wifi network tun0 - The tunnel interface As can be seen from the routes above there is no entry for 192.168.1.0/24 that routes the traffic through the tunnel interface. When I manually route a single IP like 192.168.1.16 over the tunnel gateway 192.168.6.6, this works. Q: How do I set up my routes in MacOS X for the same behaviour as on windows, to route everything except 192.168.1.1 through the tunnel, but leave the default gateway to be my local 192.168.1.1 ?

• AD domain on web servers behind NAT - DNS issues?

  - by Ant

  I'm trying to setup an AD domain to manage the security between two Windows Server 2008 webservers that will sooner or later use NLB to balance website requests. I've hit a problem which I think is a simple solution and is down to DNS. My website domain is mydomain.com. The two servers are running behind a NAT firewall on the 10.0.0.0 IP range. I've setup the AD domain to be called ad.mydomain.com (as recommended by MS and a few other answers to questions on here). The second web server however doesn't want to join the domain, and gives an error pinning the problem on DNS - "ensure that the domain name is typed correctly" even though it queries the SRV record successfully and gets the correct DC back - dc.ad.mydomain.com. Doing a dcdiag /test:dns on the DC gives the Delegation error 'DNS Server dc.mydomain.com Missing glue A record'. I have a feeling I need to add something to the public DNS so that it in some way knows about ad.mydomain.com. Can anyone suggest whether I'm on the right track in adding something to the public DNS? Or whether it's something else? Many thanks

• Allow incoming connections on Windows Server 2008 R2

  - by Richard-MX

  Good day people. First, im new to Windows Server. I've always used Linux/Apache combo, but, my client has and AWS EC2 Windows Server 2008 R2 instance and he wants everything in there. Im working with IIS and PHP enabled as Fast-CGI and everything is working, but, i cant see the websites stored in it from internet. The public DNS that AWS gave us for that instance is: http://ec2-XX-XXX-XXX-121.us-west-2.compute.amazonaws.com/ But, if i copy paste that address, i get nothing, no IIS logo or something like that. My common sense tells me that maybe the firewall could be blocking the access. Can anyone help me and tell where to enable some rules to get this thing working? I don't wanna start enabling rules at random and make the system insecure. If you need any additional info, you can ask me and i will provide it. Thanks in advance. UPDATE: Amazon EC2 display this: Public DNS: ec2-XX-XXX-XXX-121.us-west-2.compute.amazonaws.com Private DNS: ip-XX-XXX-XX-252.us-west-2.compute.internal Private IPs: XX.XXX.XX.25 In my test microinstance, i just to use the Public DNS address (the one that starts with "ec2") and it works like a charm (of course, the micro instance have its own Public DNS im not assuming same address for both instances...) However, for the large instance, i tried to do the same. Set up everything as in the micro instance but if i use the Public DNS, it doesnt load anything. Im suspicious about the Windows Firewall, but, the HTTP related stuff is enabled. What should i do to get access to the large instance? I don't want to set up the domain yet, i want access from an amazon url. 2ND EDIT: all fixed. Charles pointed that maybe Security Groups was not properly set up for the instance. He was right. Just added HTTP service to the rules and all works good.

• Multicast hostname lookups on OSX

  - by KARASZI István

  I have a problem with hostname lookups on my OSX computer. According to Apple's HK3473 document it says for v10.6: Host names that contain only one label in addition to local, for example "My-Computer.local", are resolved using Multicast DNS (Bonjour) by default. Host names that contain two or more labels in addition to local, for example "server.domain.local", are resolved using a DNS server by default. Which is not true as my testing. If I try to open a connection on my local computer to a remote port: telnet example.domain.local 22 then it will lookup the IP address with multicast DNS next to the A and AAAA lookups. This causes a two seconds lookup timeout on every lookup. Which is a lot! When I try with IPv4 only then it won't use the multicast queries to fetch the remote address just the simple A queries. telnet -4 example.domain.local 22 When I try with IPv6 only: telnet -6 example.domain.local 22 then it will lookup with multicast DNS and AAAA again, and the 2 seconds timeout delay occurs again. I've tried to create a resolver entry to my /etc/resolver/domain.local, and /etc/resolver/local.1, but none of them was working. Is there any way to disable this multicast lookups for the "two or more label addition to local" domains, or simply disable it for the selected subdomain (domain.local)? Thank you!

• Prevent outgoing traffic unless OpenVPN connection is active using pf.conf on Mac OS X

  - by Nick

  I've been able to deny all connections to external networks unless my OpenVPN connection is active using pf.conf. However, I lose Wi-Fi connectivity if the connection is broken by closing and opening the laptop lid or toggling Wi-Fi off and on again. I'm on Mac OS 10.8.1. I connect to the Web via Wi-Fi (from varying locations, including Internet cafés). The OpenVPN connection is set up with Viscosity. I have the following packet filter rules set up in /etc/pf.conf # Deny all packets unless they pass through the OpenVPN connection wifi=en1 vpn=tun0 block all set skip on lo pass on $wifi proto udp to [OpenVPN server IP address] port 443 pass on $vpn I start the packet filter service with sudo pfctl -e and load the new rules with sudo pfctl -f /etc/pf.conf. I have also edited /System/Library/LaunchDaemons/com.apple.pfctl.plist and changed the line <string>-f</string> to read <string>-ef</string> so that the packet filter launches at system startup. This all seems to works great at first: applications can only connect to the web if the OpenVPN connection is active, so I'm never leaking data over an insecure connection. But, if I close and reopen my laptop lid or turn Wi-Fi off and on again, the Wi-Fi connection is lost, and I see an exclamation mark in the Wi-Fi icon in the status bar. Clicking the Wi-Fi icon shows an "Alert: No Internet connection" message: To regain the connection, I have to disconnect and reconnect Wi-Fi, sometimes five or six times, before the "Alert: No Internet connection" message disappears and I'm able to open the VPN connection again. Other times, the Wi-Fi alert disappears of its own accord, the exclamation mark clears, and I'm able to connect again. Either way, it can take five minutes or more to get a connection again, which can be frustrating. Why does Wi-Fi report "No internet connection" after losing connectivity, and how can I diagnose this issue and fix it?

• Solaris 10: cannot ping to/from server

  - by anurag kohli

  All, I have a Solaris 10 server which is not reachable by IP (ie can't ping to/from the server). I believe I have the default route setup correctly. See below: # ifconfig -a lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 192.168.62.100 netmask ffffff00 broadcast 192.168.62.255 ether 0:14:4f:b1:9b:30 # netstat -rn Routing Table: IPv4 Destination Gateway Flags Ref Use Interface -------------------- -------------------- ----- ----- ------ --------- 192.168.62.0 192.168.62.100 U 1 40 bge0 224.0.0.0 192.168.62.100 U 1 0 bge0 default 192.168.62.1 UG 1 0 127.0.0.1 127.0.0.1 UH 1 4 lo0 # # cat /etc/defaultrouter 192.168.62.1 I have verified layer1 and layer 2 are up on the switchport, and that it's on the correct VLAN.

• How does Windows 7 DNS client work?

  - by Mark Allison

  I am using a local DHCP and DNS server on my home network on a linux machine. It is running CentOS 6.3 with dnsmasq 2.48. It's all working fine except for local DNS lookups for Windows machines only. I have a mix of Ubuntu, CentOS and Windows machines on the network, some virtual, some physical. I have a machine called boron and the domain is called localdomain If I ping boron from any linux machine, I get [root@lithium lists]# ping -c3 boron PING boron.localdomain (10.0.0.5) 56(84) bytes of data. 64 bytes from boron.localdomain (10.0.0.5): icmp_seq=1 ttl=64 time=0.740 ms 64 bytes from boron.localdomain (10.0.0.5): icmp_seq=2 ttl=64 time=0.478 ms 64 bytes from boron.localdomain (10.0.0.5): icmp_seq=3 ttl=64 time=0.458 ms --- boron.localdomain ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2000ms rtt min/avg/max/mdev = 0.458/0.558/0.740/0.131 ms If I do it from my Windows 7 machine, I get: Ping request could not find host boron.

• VMWare converter performance

  - by bellocarico

  Hello, I have a question about my test lab. It's more to understand the concept more than apply this into production: I have an ESXi with few VMs linux/windows configured and I'd like to use VMWare converter to create backups. To speedup the process I decided to create a Windows VM on the same ESXi host where I've installed Windows 7 and VMWare Converter. The Host has a gigabit card but it's currently connected to a 100Mb FD port. Windows 7 sees a 1gb card connected. When I do the backup using VMWare converter I specify the host IP as source and destination, so I thought the copy could be faster then use my laptop across the network. Well, to cut a long sotry short: I get dreadful performance (4Mb/sec). I'm a buit confused on this because despite the fact that the host is running 100Mb communication between VMs and hosts shouldn't (correct me if I'm wrong) have any limitation instead. I did tweak windows 7 to optimise network performane but I got just a little improvement. i still need 4 hours to back up a 50Gb (thin) VM. Additionally I wanted to ask: Would jumbo frame help in this? I know that jumbo frame have to be supported end to end, and the network switch where the host is currently connected doesn't support this, but I was wondering: 1) Does ESXi host support jumbo frames at all? 2) Can I enable it somehow? 3) If I do so, I guess bulk transfert between VMs and host would improve, but would this affect the communication going through the real switch as this doesn't do jumbo? Thanks for reading

• OpenVZ Can't initialize containers after install

  - by Tonino Jankov

  I have installed OpenVZ on centos 6 on a dedicated server. I followed quick installation guide on openvz wiki. After installing thru yum, I don't know why, but grub.conf wasn't automatically updated to accomodate new kernel, so I had to do it manually. I edited grub.conf, added openvz kernel and rebooted - it went fine. Server went up into openvz kernel and it worked, it started openvz service byitself.

• Connection refused after installing vsftp on Ubuntu 8.04 with fail2ban

  - by Patrick

  I have been using an Ubuntu 8.04 server with fail2ban for a while now (12+ months) and using ftp over SSH without any problems. I have a new user that needs to put files onto the server from an IP modem. I have installed vsftp (sudo apt-get install vsftp) and everything installed correctly. I have created an ftp user on the server following this guide. Whenever I try to connect to the server with my ftp program (filezilla) I get an immediate response of: Connection attempt failed with "ECONNREFUSED - Connection refused by server". I have looked into fail2ban and cannot find any problems. The iptables setup is: Chain INPUT (policy ACCEPT) target prot opt source destination fail2ban-ssh tcp -- anywhere anywhere multiport dports ssh Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain fail2ban-ssh (1 references) target prot opt source destination RETURN all -- anywhere anywhere VSFTP config file (commented lines removed) listen=YES anonymous_enable=NO local_enable=YES write_enable=YES dirmessage_enable=YES xferlog_enable=YES connect_from_port_20=YES chown_uploads=YES chown_username=[username] secure_chroot_dir=/var/run/vsftpd pam_service_name=vsftpd rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key Any ideas on what is preventing access to the server?

• Filesharing mac 10.6 with windows vista

  - by adam

  Ive followed all the tutorials on the net to no avail. I can see my vista pc in finder on the mac but when I click on it tries to connect but fails. The same is true from vista, it can see the mac but i cant connect. Wont even offer a login box. So I tried to troubleshoot by using a 3rd computer with xp. It joined the network and can access both the mac and vista on the same workgroup. Mac sees it and it shows under finder but i cant access it by clicking on the icon i have to access by using the ip of the xp machine...strange. Ive turned off all my firewalls. The fact that xp can connnet to the others and vice versa boggles my mind why vista and mac cant connect directly. Oh and pings indicates the same. I.e. xp has no problem but mac to vista and vice versa fails. Can anyone help.

• WEIRD netstat behavior on Windows XP re: www.partypoker.com

  - by tbone

  I really don't know if this is the right place to ask this, but I would really appreciate if someone that is more savvy on Windows XP (Professional) could help me out. For background, I am a 10+ years programmer, so I'm not a total idiot, but I am far from an expert on TCP/IP, etc, and this has me totally confused. When I do a netstat (on Windows XP) I seem to always get a huge amount of www.partypoker.com connections and I can't figure out where they are coming from. A netstat -o shows me that some are coming from PID xxx, which is firefox, but if I kill it, the connections still remain. Some are coming from PID 0, which makes no sense to me. SECOND PROBLEM: One would think you could edit the C:\WINDOWS\system32\drivers\etc\hosts file to block this, but it seems like my machine is ignoring the hosts file! (I have tried with the DNS client service both enabled and disabled, same result). So I just rebooted, killed all my normal programs, and I can't seem to reproduce the problem. If I was a paranoid person, I would think there was some sort of an intelligent trojan running. I am running Windows XP Pro, Kaspersky Antivirus, ccCleaner, and am fully up to date on Windows Update. What gives???? So, I guess my questions are: 1. Is anyone else seeing these wird connections to partypoker.com? 2. Why isn't my hosts filter working? 3. Is there some utility I can run to find out whats happening? I've tried autoruns.exe from sysinternals but don't see anything interesting. Am I the only one with this problem? If there are any additional things you need me to run, let me know.

• NAT confusion regarding cisco ASA5510

  - by LonelyLonelyNetworkN00b

  I'm setting up my first cisco firewalls. A little information first:I have two asa5510 setup in a working active/standby pair. From my ISP i have two public subnets. A /29 and a /26. On my DMZ interface i have the /26 configured. On my WAN Interface i have configured the /29 IPs. My isp routes the /26 via the /29 primary IP. I'm running ASA 8.2. I've turned NAT-Control off, because i don't want to use nat for for other than some internal interfaces. In essence i don't want to use NAT unless i specify it. I have a internal interface with the network of 192.168.100.0/24. I've tried setting up nat limke this: nat (inside) 1 192.168.100.0 255.255.255.0 global (WAN) 1 interface I was under the impression that this would let connections that was going from 192.168.100.0/24 and out the WAN interface to be Port-Address-translated. I'm not getting this to work for some reason. Inside interface has security level of 100, and wan has security level of 0.

• Shorewall log question.

  - by Shikoru

  I have been getting various attempts to connect to ports on my shorewall firewall. The ports that I keep seeing connection attempts at are tcp 44444, tcp 44446, udp 55555 and every now and then some slight variation. I ran "netstat -a" and did not see anything listening on those ports. Is this something that I should be worried about or is it just some rouge computers out there? I have noticed alot of the ip addresses are from Spain and Mexico.

• Using Varnish (only) for DDoS mitigation

  - by Martin Kanters

  My VPS is suffering from a (D)DoS doing a SYN flood with spoofed IPs. I'm right now searching from ways how to be able to defend (at least a bit) against it. It's running a DirectAdmin apache2 webserver. Mainly used for serving PHP and MySQL. We are using CloudFlare, which are saying that they are able to mitigate (D)DoS at some level, now the attacker knows our real IP address, so CloudFlare isn't helping a bit. I've done some searching on the net and found out about enabling SYN cookies, to defend against it. I've checked my settings and it seems it was enabled all along. I've also read about that Varnish is able to defend against SYN flooding and Slowloris attacks, now I'm pretty interested in using that. The thing is that CloudFlare is already caching a lot from us, and I don't wish to spend too much resources on Varnish. Is it possible and smart to set up Varnish only for the better handling of requests? Are there perhaps better ways which I've missed? Thanks in advance, Martin

• VPN - Accessing computer outside of network. Only works one way

  - by Dan

  I could use some help here. My ideal goal is to create a VPN for 2 macs that are in different locations so that they can share each others screens and share files. I basically want to do what Logmein's Hamachi does, but without the 5 user limitation. I have set up the VPN on my Synology NAS at my house using the PPTP protocol. I could also use OpenVPN. The good news is that I can use a laptop outside of my home network to access any computer on my network at my house. The bad news is that I can not do the reverse. I want to use a computer in my home network (same network as the VPN server) to access a computer outside of my network (which is connected via VPN successfully). My internal IP is 192.168.1.xxx PPTP VPN assigns my laptop that is outside of my network with 192.168.5.xxx, but when I try to access it remotely either with afp://192.168.5.xxx or vnc://192.168.5.xxx I can't connect using either. Is this something that I should be able to do or is VPN only one way? I've also tried openvpn with the same results. Thanks for any help! -Dan

• Mac computers unable to connect to samba

  - by tan-ce

  I have a Ubuntu 9 server with samba 3.3 installed. This server has two network interfaces, one to a "public network" which I do not have any control over and another to a private LAN. On the private LAN, samba is the Domain Controller and nmbd is the WINS server on that network. On the "public network", I have configured a second instance of nmbd to run as a WINS client. The setup seems to work fine for Windows XP (on the domain or otherwise) as well as other Ubuntu machines. Finally, my question: Mac computers seem unable to connect to the samba server. As far as I can tell, it is as if samba is invisible to the MAC computer. Could my configuration of nmbd be causing this problem? Or is this simple a Mac oddity and is there anything I can do about it? New updates/info: We tried to connect through the Finder - Connect to Server, we entered smb://servername where servername is the netbios and DNS name. (There is also a DNS entry for the same name on the network) We also tried connecting by IP address Also, I just realized that there is at least one Mac which can connect. (Leopard 10.5.8) I will try to get the Mac OS versions of the computers which couldn't connect as soon as I can. The Mac which could not connect was running Mac OS X 10.4.11. Was there a change to samba on Mac OS between 10.4 and 10.5?
