  • XenServer: Editing clone configuration before boot

    - by Jeff Ferland
    Upon cloning a base image, I need to reconfigure basic settings. Regenerating the ssh host key, changing static IP assignments, setting the host name, etc. Because of the network setup, DHCP is not an option. That more or less rules out SSHing in with a predefined key or running a startup script since I can't provide the IP externally. I'd most like to mount the filesystem of the new machine on Dom0, but the lvm volumes are exported and it appears to be Bad Form to import them so the Dom0 machine can see them. What's your best suggestion for altering files in a cloned VM before boot? Must be non-interactive, and I'm going to guess out the gate that scripting access via xe console is not going to work well.

  • postfix specify limited relay domain while allowing sasl-auth relay

    - by tylerl
    I'm trying to set up postfix to allow relaying under a limited set of conditions: The destination domain is one of a pre-defined list -or- The client successfully logs in Here's the relevant bits o' config: smtpd_sasl_auth_enable=yes relay_domains=example.com smtpd_recipient_restrictions=permit_auth_destination,reject_unauth_destination smtpd_client_restrictions=permit_sasl_authenticated,reject The problem is that it requires that BOTH restrictions be satisfied, rather than either-or. Which is to say, it only allows relaying if the client is authenticated AND the recipient domain is @example.com. Instead, I need it to allow relaying if either one of the requirements is satisfied. How do I do this without resorting to running SMTP on two separate ports with different rules? Note: The context is an outbound-use-only (bound to 127.0.0.1) MTA on a shared web server which all site owners are allowed to relay mail to one of the "owned" domains (not server-local, though), and for which a limited set of "trusted" site owners are allowed to relay mail without restriction provided they have a valid SMTP login.

  • Block P2P traffic on a Linksys router WRT54G with tomato firmware

    - by Kami
    Hi, I'm running a small wireless network (6 to 10 users) on a Lynksys WRT54G with tomato firmware sharing an internet connection. I don't want the users to download files with bittorrent (mainly used) and other p2p apps. I've also found some solutions about lowering p2p traffic priority using QoS. I really need to BAN p2p traffic. Does anyone know how to setup some rules to deny that kind of traffic ? I've tried to setup an Access Restriction Rule: But it's not working at all ...

  • Gradually migrate from one SMTP server to another

    - by Bart van Wissen
    I maintain an application that sends out a ton of e-mail on a daily basis. Soon, we will have to migrate to another SMTP-server for that, which has an ip address that has no reputation with respect to email delivery. So instead of just flipping the switch, I would like to start by sending a small percentage of all mail through the new server, and then gradually increase that percentage until we reach 100%. It wouldn't be very hard to implement something in the application itself, but I would like to know if there is an easier, more reliable out-of-the-box-type solution for this. My first thought was to use round-robin DNS for this, but the servers require different credentials, use different protocols (one uses SASL, the other doesn't) and even different port numbers, so I think that rules out the DNS based solution. Is there any way, for example, to configure Postfix to send 1 out of x e-mails to relay host A and the rest to relay host B? Or perhaps a different MTA?

  • Port forwarding no longer works

    - by Auryn
    Prior to testing an OpenVPN installation, I setup a basic VPN server using the software already built into Windows 7. Port forwarding on the Linksys router worked as normal and I was able to connect remotely. After doing an install of OpenVPN Access Server on a spare box running Ubuntu, and adding new ports to be forwarded I was unable to access the VPN from an external source as the required ports all indicated that they were closed. (During testing XRDP and VNCSERVER were also installed to facilitate access to the box) Checking back on the Windows 7 VPN resulted in no access to that vpn setup either. All ports are now reporting a being closed despite being previously open even ports that were being used for other services. Adding and removing port forwarding rules seem to have no effect. At this point, in order to troubleshoot, both the firewall and anti-virus software have been disabled on the Windows 7 machine. Could this be just a router issue? Is there any way out of this without having to reset and reconfigure the router?

  • Squid 3 reloading makes it stop serving requests

    - by coredump
    So, we use Squid 3 here (3.0.STABLE8-3+lenny4), pretty standard configuration (no dansguardian or similar) + NTLM authentication with LDAP background, circa 1000 users on a busy day, and our acls reference some external files (allowed/blocked sites/ip addresses). On Squid 2.X we used to be capable of reloading it's configuration (to add or sites or addresses to rules, etc) and squid would not stop serving during the reload. Since we changed to 3.0, that seems to be impossible: everytime we use reload (or -k reconfigure) it stop serving requests for as long as 2 minutes, and clients receive a Configured proxy is not accepting connections message. I checked the documentation and got nothing about it, does anyone else suffer from this problem or is it a isolated case on my setup? Also, if you have Squid 3.0 and doesn't suffer from this problem, how is your squid configured?

  • Is it possible to interop with Thunderbird using C#?

    - by Jurily
    Here's the latest hurdle in my ongoing quest to automate my job: All email in the company goes through 4 different email adresses, switching randomly back and forth (with a note attached in the global share: please set "keep email on server") All logic related to email is contained in a nice big Thunderbird profile, which gets copied back and forth to new machines; this includes sorting invoices into 5 different "folders", the list of VIP adresses to send notifications, and the VIP level of those customers I only need the contents of those folders (the attachments, anyway) The question: is there a way to ask Thunderbird for those attachments and lists from C#? Alternatively, can Outlook be set up to synchronize with Thunderbird? Where do I start reading? Ditching Thunderbird is not an option right now, I need to keep up with changes to the VIP list. P.S. I will set up a real email server right after Monkey saves me enough time to convince people about it.

  • openldap search acl

    - by Patrick
    I'm trying to write an access control for OpenLDAP to allow a user to search with a certain base dn, but only get results back from certain sub dn's. I've played with lots of different rules but cant get it to work. I'm not sure its even possible. For example: I have the user with the dn uid=testuser,ou=people,dc=example,dc=com. I want this user to be able to search with a base of dc=example,dc=com and get back entries in ou=people,dc=example,dc=com. There are lots of other sub OUs under dc=example,dc=com, but only entries in ou=people should be returned (for bonus, I'd only like certain attributes to be returned as well). Can this be done?

  • allow SSH to bypass VPN on OSX mavericks, openvpn, pf

    - by zycho42
    My home computer connects to the internet through an OpenVPN connection. However, I would like to be able to connect to my home computer from outside over ssh. Ssh is set up and working, but when I connect to the vpn ssh is only accessible from inside my home network. I figure what's going wrong is my router forwards incoming ssh connections to my mac, but then my mac replies over the vpn, so the connection from outside times out. I've got pf set up for a couple of other things, but I can't figure out how to let the ssh replies bypass the vpn using pf. I've come across other solutions that use ip tables, routing tables and rules, but I can't figure out how to set that up on mavericks. I've been searching for this for a while now but I haven't found a working solution. Any help would be greatly appreciated!

  • Can I use MX records to deliver some addresses to Google Apps and some to my server?

    - by Josh
    I have whm installed on my VPS, which my domain MX records are pointing to: 0:mail.mydomain.com and whm/cpanel has mail forwarding rules which pipes certain @mydomain email addresses into my CRM software. But for certain email addresses I want to forward into Google Apps. For example, [email protected], [email protected] pipes into cPanel -- CRM (mail.mydomain.com) but [email protected] should be going to Google MX records. Is that possible? The reason why is I want to register for Google Apps such as analytics and other Google services under [email protected]. My initial thoughts were to add a subdomain such as [email protected] and point that subdomain's MX records to Google.. but I want to avoid this if possible.

  • When to increase AWS RDS MySQL Server instance to larger CPU/RAM?

    - by rksprst
    I'm wondering at what stage do I need to increase the image for the RDS MySQL server to a larger CPU/RAM instance. The CPU utilization graph is near 0. The Avg Free Memory is around 150MB. The Avg Swap Usage is 420MB. Read Latency is 0-20ms/op it spikes up randomly. Avg write latency is on average 5ms/op but spikes up to 10-20ms/op. Are there some common rules here that I should follow? Thanks!

  • Proxification rulte for System process

    - by kseen
    I'm trying to configure Microsoft Visual Studio 2010 remote debugging and ran into issue: while connecting to remote computer running MSVSMON, client computer sends SYN request for connection. It makes it under the System process (as I see it in TCPView). As every network apps should be configured to use proxy in our network, I'm trying to add devenv.exe to proxification rules to make its traffic goes thru LAN's proxy server. It doesn't help. So my question is how can I make that low-level-system traffic will go through local area network proxy server?

  • Why is port 444 open on this router?

    - by TJ Thind
    I have a Cisco RV110W. I ran nmap at it from the outside and nmap reports that the router has tcp port 444 open. Yet there are no port forwarding rules specifying this port. It should as far as I can tell, be closed. There's even a service listening to that port which I can connect to through telnet. I threw some SNPP commands at it but the service doesn't respond to any of them so I don't believe it's SNPP. Does anyone have any idea why this particular router has tcp port 444 open? I haven't been able to find anything in the manual or on Cisco's website.

  • Cron stopped working, partially working.

    - by Robi
    Our cron script stopped working in different dates in August. What can be the possible reasons? We did not change anything. Our hosting showed us a log where we can see that cron is executing our scripts. But, nothing is happening in our scripts. If we manually execute the scripts, we're getting correct results like before. I showed the commands to hosting and they showed me that the commands are working. What should I tell my hosting? what should I do? They are php scripts which are executed by CRON and they just post to facebook and twitter. They don't execute any hard or huge things. I even asked my hosting if we broke any rules.

  • Linux box acting as wireless access point to share the internet connection

    - by Suresh
    A linux machine is connected to internet over two interfaces ppp0 and ppp1 using two modems. Also this machine acts as wireless access point through an interface say, eth0 with ip address 192.168.1.1 and acts as gateway for the connected devices through this network with subnet mask 255.255.255.0 Now is it possible to achieve the following: When any of the connected devices through wireless AP needs internet connection linux machine has to use ppp1 interface for internet. If any of the applications on the linux machine needs internet connection linux machine should use ppp0 interface for the internet. Can this be achieved by adding rules to chains in filter/nat tables? If the kernel routing table has a default rule to route the default traffic through interface ppp0, wil kernel completely ignore ppp1 for internet? PS: new to networking and routing concepts, If the question is not clear leave a comment, will try to give more information.

  • Routing only some local IPs through VPN on dd-wrt

    - by bo-inge-ostberg
    Much similar to this entry: http://serverfault.com/questions/94283/using-dd-wrt-to-connect-to-vpn-and-forward-all-traffic-of-certain-devices-through , I have set up my router with dd-wrt + OpenVPN to connect to a VPN. This works fine, and all traffic from behind the router goes through the VPN. How do I route(?) traffic in the router so that only certain IPs from the LAN will go through the VPN, while the others take the "normal" route? Is it also possible to allow traffic from certain local IPs to go ONLY through the VPN, making it impossible for them to use the regular internet connection if the VPN is down? I know this question was answered in the post I linked to, but that just doesn't seem to work for me. The routing table and rules change, but traffic still just goes through the VPN.

  • Managing Active Directory Group Membership with a Non-Administrator Account In Server 2008

    - by Laranostz
    I am running Server 2008 R2 in an Active Directory Domain Environment. I have created a group in Active Directory and I have delegated management authority to that group to a user. I want this user to be able to add and remove accounts as needed from that group so that they are exercising some measurement of control without giving them other authority. When I have the user attempt to access the Active Directory Users & Computers Console it prompts them for Administrator credentials. They are using Remote Desktop to access the server, because they do not have Windows 7, and firewall rules prevent using the Remote Management Kit. I do not want to provide them with any level of Administrative rights except the minimum required for them to add/remove users from this group. There are two servers that 'talk' to each other in this isolated environment, a domain controller and a member server, both are only reachable through RDP. Any suggestions?

  • How to test if SYN and FIN are both dropped at the same time in hping3?

    One of the rules to prevent unexpected attack is to prevent SYN & FIN being used together. SYN and FIN are both set $IPT -A INPUT -p tcp --tcp-flags SYN,FIN SYN,FIN -j DROP How do I use hping to test if this iptable rule works? hping3 192.168.7.0 --keep -S -F??? Is this complete? When just type iptables -L, it shows: Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere DROP tcp -- anywhere anywhere tcp flags:FIN,SYN/FIN,SYN WHY do I need to put the "SYN,FIN" twice before drop? Is it because one for source and one for destination?

  • Cant logon to domain over site-to-site vpn

    - by 3molo
    Tied together branch office with main office over two Cisco ASAs. The (internal) networks on either side can communicate with the other. I can ping, use the DC's DNS service and even join a domain on a new client. I can't however logon, I get the "domain controller is not available" error message on client. I find nothing peculiar in DC's event logs. Sicne it's site-to-site (with ping), it's always up so it should work. No firewall rules (except allow any any) between the two networks (of either side). Main site internal net: 10.10.10.0/24 Branch office net: 10.180.3.0/24 Am I overlooking something here? Where should I start investigating this?d

  • Sendmail to local domain ignoring MX records (part 2)

    - by FractalizeR
    Hello. I have the exact problem, like in this post: http://serverfault.com/questions/25068/sendmail-to-local-domain-ignoring-mx-records I am also using email provider like GMail For Your Domain (which stores your mail and manages it). I am sending mail from my server directly, but receiving mail is done via Yandex (email provider). Since the server hosts forum, I prefer to send mail directly from it because using another mail provider can slow things. Also, when I send 300.000 emails to my subscribers, email provider will surely block me thinking I send spam. My DNS zone now is: ; ; GSMFORUM.RU ; $TTL 1H gsmforum.ru. SOA ns1.hc.ru. support.hc.ru. ( 2009122268 ; Serial 1H ; Refresh 30M ; Retry 1W ; Expire 1H ) ; Minimum gsmforum.ru. NS ns1.hc.ru. gsmforum.ru. NS ns2.hc.ru. @ A 79.174.68.223 *.gsmforum.ru. CNAME @ ns1 A 79.174.68.223 ns2 A 79.174.68.224 @ MX 10 mx.yandex.ru. mail CNAME domain.mail.yandex.net. yamail-xxxxxxxxx CNAME mail.yandex.ru. Server hostname is server.gsmforum.ru. May be this is the cause? Can someone explain the reason of the matter (the rules that make sendmail consider domain to be local)? Can I easily change *.gsmforum.ru. CNAME @ into *.gsmforum.ru. A 79.174.68.224 to solve this problem? [root@server ~]# cat /etc/mail/local-host-names localhost localhost.localdomain This server hosts gsmforum.ru so I cannot put it into another domain like David Mackintosh suggests. Putting domain in mailertable doesn't solve the problem also. sendmail -bt still shows, that address is local. DontProbeInterfaces is also set to true at sendmail config.

  • What advantages does mod_evasive have over mod_security2 in terms of DDOS protection?

    - by Martynas Sušinskas
    Good day, I'm running an Apache2 server in front of a Tomcat and I need to implement a DDOS protection mechanism on the Apache2 layer. I have two candidates: mod_evasive and mod_security2 with the OWASP core rule set. Mod_security is already installed for overall protection, but the question is: is it worth adding mod_evasive besides mod_security just for the DDOS (does it have any major advantages) or the OWASP crs rules in the /experimental_rules/ directory (modsecurity_crs_11_dos_protection.conf) provide the same protection? Or it's just a matter of preference? The sites are not very high traffic normally. Thank you for your answers, Martynas
