Is there a way to run queries against a Microsoft sql server from linux? Here is what I would like to do. When I create apps that us db back end I would like to quickly check results of my queries. so if I could do something like "select * form Orders" from the terminal or another app that would be great.
View 6 RepliesI'm trying to connect to a Win XP computer via Remote Desktop/Terminal Server. (Note: WinXP refers to Remote Desktop, or RDP; Ubuntu uses Terminal Server client for this function.)
The problem is that my XP computer requires the use of Microsoft's RDP version 6 because it uses a Terminal Server Gateway. The TS client in Ubuntu is compatible with version 5, not version 6.
Is there a MS RDP version 6 compatible program/client for Linux?

How often are dns queries sent? Assume I want to connect to a ssh server, will I send one dns-query in order to do that or do I send multiple during my connection? What if I request web-pages, do I send a query only when I enter a site or will I send queries every time I visit a new page on that site?
I'm asking since I'm considering getting an account at dyn.com (the standard account for $30/yr) and it comes with 600 000 queries per month (which is way more than I expect to get but knowing exactly what it means is always good).

I have this ISP grade Nameserver running on BIND 9.5 on Fedora Core 9 64 Bit.
Its been pretty working well for sometime until a last week when we noticed it stopped resolving for our clients using on our service.
It gives correct authouritative answers for our own ISP domain with the A, PTR and MX intact but does not return resolving queries back to clients.
Below are my files
This is the message from /var/log/messages
The 41.223.x.x and 41.215.x.x ip address are from our ISP subnet and so are our own clients being denied.
The box is also hosting our traffic graph server which is on a LAMP but listens on another IP/ethernet card.
So far the load on the server is minimal as is a Dell R200 rack server.
I chose -Server-, if this is more appropriate in -Networking-, just let me know. Basically, I need to be able to merge responses stored in a zone file with responses from an "upstream" authoritative server. I'm in the sad position of needing to "intercept" requests to *part* of a domain (but not restricted to a sub-domain!) and return results for *some* hosts that use an internally routed address, and results for the rest using the public internet addresses. Unfortunately, it's not my domain, so I can't just use views (although I suspect they could end up having some part to play in this, at least potentially)... but instead I have to actually send requests recursing to the other site's external DNS for any hosts my server doesn't have records for in the zone file.
Some background on the situation:
I work at a local government, which has a private link / VPN connection to a state government entity, and needs to use internal addresses for some of the state servers, which then get routed over an "internal" network link. But the state uses the same domain name internally and externally, just presenting views to internal clients vs. external clients. -- However, we are only being allowed access to certain of their servers through the internal link, which means that for any other servers that we don't have internal/private access for, we have to visit the public addresses just like anyone else on the internet... So, I can't just send all requests to their internal DNS and get responses, because we'd get IPs for some servers (e.g. their main web site) that we wouldn't then be able to reach using the internal network link.
For Example: Say I have a client machine, "client1", on my network ("my.net"), which uses "mydns1.my.net" for name resolution ... and which needs to access 2 servers on the state network, "private.st.us" and "public.st.us" -- so named based on how "my.net" needs to access them.
The external state DNS server/view ("ext-dns.st.us") responds to requests with something like:
private.st.us -- 1.2.3.456
public.st.us -- 1.2.3.457
(Those are just crap addresses, obviously.
The internal state DNS server/view ("int-dns.st.us") responds to requests with something like:
private.st.us -- 10.0.0.8
public.st.us -- 10.0.0.10
This works on their network because their own clients have access to all such IPs.
But for us, they only allow traffic flowing between "my.net" and their internal network to reach the 10.0.0.8 address, blocking all other address destinations. So, when "client1.my.net" asks "mydns1.my.net" for the address of "public.st.us", I need "mydns1" to recurse out to "ext-dns.st.us" to get an answer (1.2.3.457) and then return that IP to "client1" -- because "my.net" is blocked from accessing the server's 10.0.0.10 address. But, when client1 asks mydns1 for "private.st.us" I need to pull the IP (10.0.0.8) from a local zone file instead of asking either of the state DNS servers -- or optionally forward the request to "int-dns.st.us" I suppose -- because the state blocks access to certain services (which we need and are the whole cause of this problem!) via the public (1.2.3.456) address.
I can configure a caching-only name server fine, but how do I make it forward DNS queries too?
I'm thinking I could add the below to the options stanza in the /etc/named.conf file:
trying to configure a Centos 5.5 server (simple file server with DHCP and DNS relay). I configured and tested the config (by 'service dnsmasq configtest') of dnsmasq and I got the message 'dnsdomain:host unknown (translation of the real message : hte inconnu) and I didn't find where I could define this host ! The hostname of the server is well defined and I can see it from all Windows PC's on the LAN. dnsmasq starts (with hte same message as in configtest) but when querying DNS from PC's te.g. trying to surf the Internet), I don't get replies (3 DNS servers are also well defined and operational).

I have registered 2 nameservers running bind for a certain domain. The log file of my domain name provider (SWITCH) shows the following warning:
Warning Der Name-Server ns.xxxxx.ch (nn.nn.nn.nn) beantwortet rekursive Anfragen.
In English that would be:
Warning: Name-Server ns.xxxxx.ch (nn.nn.nn.nn) answers recursive queries.
The NS triggering the warning is running openSUSE 10.2 and the other one 11.1. Both configuration files /etc/named.conf are equivalent (well, forwarders are different). There is no such warning for the NS with 11.1. When I add "recursion no;" to the options in /etc/named.conf the warning goes away, but FF or SeaMonkey running on the server no longer get their DNS requests resolved.
I recently turned on query logging on our name server and immediately saw repeated queries for . (dot). I've not seen this before. It looks like a really sloppy DOS. What would this return if my NS was misconfigured?

If it is so then what out of the following should IDEALLY be created as primary partition ?
/usr
/home
/boot
I think /usr and /home both need a primary partition , then what about /boot, Will I be not able to recover something in case of failure if I don't set /boot as a primary partition ?

View 3 Replies View RelatedI have a Debian testing system on a laptop that used to have Windows 8 on it. I kept the EFI boatloader and its partition, but now every time the system boots, it first tries to boot into Windows (which isn't there anymore). Removing /boot/efi/EFI/Microsoft just leads to an error message when booting, with some component of Windows still trying to load and not finding those files.
The workaround for now is to go into the UEFI boot menu on every boot and selecting the "debian" entry, which works but is a bit cumbersome.How can I get rid of the Microsoft loader completely? I find a lot about repairing or re-adding the Windows bootloader, but nothing about removing it.
