[Bug 1452879] Re: clamav-daemon fails after update
No, installed clamav as part of amavis. update of signatures happens via freshclam. I circumvent this by reinstalling libclamav6. But I doubt that installing this library regularly after every upgrade should be a solution. usually happens after an update of clamav or the kernel. I also suspected the disk to be the cause. Negative. Thorough scans demonstrate no errors on the disk. I use LVM. Maybe the lvm corrupts the library. But then: Why only parts of clam? I checked for a sign that the server is compromised (or partly compromised). Negative (to my best understanding). No signs of network access from outside (used an independent network based IDS on my NAS). So I think (unless you inform me to the better), that the issue lies within clamav-daemon and the libclamav6. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to clamav in Ubuntu. https://bugs.launchpad.net/bugs/1452879 Title: clamav-daemon fails after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/clamav/+bug/1452879/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 998712] Re: domain name completion broken when dnsmasq is used
Lots of speculations here. My internal DNS server is 10.1.0.4. My fallback is the secondary 10.1.0.254 which acts as DNS forwarder and proxy to the third and others. The resolver works its way down: All things well = 10.1.0.4 Main server down: 10.1.0.254 will serve rudimentary internal services and redirects all requests to external DNSs The third server is there as we need two DNS servers for official domain name registrations. I have another issue: If dnsmasq is on via Network Manager opening a VPN connection to a remote site violates all name resolution to internal addresses (10.x.x.x). Here is the catch: If I turn off dnsmasq, all things work as expected. Names get resolved correctyl in all networks (internal, remote and external). I travel a lot and have my notebook set to attach in all these networks automatically. It worked fine until dnsmasq was introduced. I doubt that dnsmasq queries D-Bus for name resolution. And even if so, I question if there is an order that says D-bus, then resolv.conf or vice versa. To verify this, I will download the source and look into how dnsmasq works internally. I even question if my current understanding how DNS works is even accurate. There are so many RFCs that cover DNS mDNS and others that I need to update my knowledge first. I would not want you to search for something that actually does not exist. All I can confirm at the moment is that disabling dnsmasq (even if that implies doing this on a multitude of machines) leads to a constantly working infrastructure with far better performance. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/998712 Title: domain name completion broken when dnsmasq is used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/998712/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 998712] Re: domain name completion broken when dnsmasq is used
First the bad news. Name resolution drops after a few minutes of inactivity (approx. 30mins). Same phenomenon as before. Second: The name server answers as soon as the request arrives. dnsmasq obviously takes some time to determine if it can serve the name itself. So back to square one: disabling dnsmasq: immediate and correct name resolution (I am talking about not recognisable delays). enabling dnsmasq the problems begin (with a difference if set to strict-order). Name resolution takes Name resolution after reboot and resume now work fine. Unfortunately after some time it does not any more. Same symptoms as without strict- order. Just read the man-pages: -o serves in the order resolv.conf offers! but here is what my resolv.conf looks like # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 127.0.1.1 search rsb.intern rsb.at So it refers to itself. There is no dnsmasq.conf file where the dns servers are defined (not installed by default).

[Bug 998712] Re: domain name completion broken when dnsmasq is used
Did some testing I set up the strict-order using the file approach as described above. I see no different behaviour. My bind does not get any queries at all. dnsmasq does not forward requests. Applications like Evolution or Thunderbird break on every reboot or resume. It takes up to 3 minutes for them to get a hold of the right server settings. The only working solution is turing dnsmasq off. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/998712 Title: domain name completion broken when dnsmasq is used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/998712/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

carried out some suspend/resume tests worked fine. tried some pings with name resolution: It takes a long time to resolve the name but it works seems that strict-order is the way to go in installations where an internal DNS is supported by external backups / extensions Can that be automated during setup? It should be pretty obvious that if there is a DNS server on the same LAN segment that it is preferable to any DNS on a different LAN.

[Bug 998712] Re: domain name completion broken when dnsmasq is used
Now I understand what you are getting at (took me a long time). I can confirm that my DNS server serves any request from inside the network. I have a log on the router monitoring outgoing traffic. Under NO circumstances is a DNS request going out UNLESS the internal server is down but the clients still have their DHCP settings. I verify this regularly as part of my error testing procedures. This is why I even use an external DNS server as my bind forwards DNS requests in case it cannot resolve them itself. Now there could be a client timeout (which occures in very rare cases, say once a year per client). In that case, the browser (which is the only app that might get affected) will simply provide a 404 page and a reload usually works. None of my dnsmasqed clients requests from the external server when our internal bind is up. I will try to put dnsmasq into strict mode for testing. Get back to you with results after some time.

[Bug 998712] Re: domain name completion broken when dnsmasq is used
Thomas, I understand that you have not set up a simulation test bed and that your questions are directed to understand the problem. You have found out that you may have misinterpreted some pieces. Reggie seems to have the same problem as I (and to my knowledge more than a dozen of others) have. I have described the issues dnsmasq has somewhere else. Here is another observation I can offer: eliminating dnsmasq makes machines respond within seconds. Network reconnect after resume from sleep as well as after a reboot works immediately. Thunderbird (another issue I submitted) connects to the mail server without problems. using dnsmasq, network reconnect (over WLAN) takes significantly longer (almost 5 secs). Even though ping and dig resolv host names correctly (in out case s4 or mail.rsb.intern) Thunderbird does not connect. That implies that the connection dnsmasq and resolver libraries is broken as well. It works eventually (say after 1min or 5, not preproducably different). Curiously it stops working again even when the machine continues to operate. Again: This was tested on several machines. And, yes: Disabling dnsmasq in NetworkManager.conf resolves ALL issues at once: Network reconnect in less than a second, name resolution to mail and mail.rsb.intern works fine (what else should the search path hold?). Referring to my reluctance of giving more than the basic information: Everyone can read Launchpad entries. This is a severe security issue. I try to be helpful but if you do not have the means to provide significant testing equipment, maybe taking dnsmasq out of an LTS would be the better solution. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/998712 Title: domain name completion broken when dnsmasq is used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/998712/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

It takes about 1 to 30 minutes to resolve the issue. On some machines it never settles itself. Certainly, if I manually adjust /etc/resolv.conf everthing works fine immediately (name resolution, access to services). If I keep the files the way they are, it is pure coincidence whether dns works (I had the chance to use a wired LAN recently and it seems to be the same issue there). My guess would be that network manager and dns-mask do not work together in all cases (in fact, they do cooperate only in just one case, after a reboot). As I never reboot machines (if I don't have to), I put machines to sleep, connect, disconnect, I practically never run into the optimal situation. Hope this helps.

[Bug 998712] [NEW] dnsmasq integration into name resolution broken
Public bug reported: dnsmasq does not resolve DNS names correcty. Applications like Thunderbird or tools like ssh rely on working name resolution. However, if there never was a working name resolution, dnsmasq never gets to know about the DNS names.
