Ubuntu Servers :: ClamAV-freshclam Does Wierd On Network?
Apr 25, 2010
I have installed my first Ubuntu server today. It is connected to our corporate network. On this network there is a Windows 2008 R2 server that serves as DNS Exchange and file server. For some unknown reason this Windows server looses network connection when the ubuntu server comes online. After some investigation the network connection is instantly restored when I stop the clamav-freshclam service on the ubuntu server. When I start the service the network connection of the Windows server goes down.The only "link" with the Windows service and the Ubuntu server is that the Windows server is configure as the nameserver on the ubuntu server.
I want to run this in production because the ubuntu will serve as anti-spam server. I need to understand what is happing and why to prevent this.

downloaded clamav and clam-db using install/remove software in opensuse 11.3 gnome.
tried to update virusdatabase typing freshclam in command-line
gives me this:
alexander@linux-y54v:~> freshclam
ERROR: Can't create temporary directory /var/lib/clamav/clamav-7d1c24383b9425dfebb5c660374d507b
Hint: The database directory must be writable for UID 1000 or GID 100

I keep getting the message code...
I am not clear why clamd.log and freshclam keep changing permission and ownership to clamav.

I have installed ClamAV 0.95.3 into Ubuntu 9.10 (i386) fully patched
I am behind an authenticating proxy, so I've entered these details into freshclam.conf:
HTTPProxyServer myproxy.com
HTTPProxyPort 1234
HTTPProxyUsername myusername
HTTPProxyPassword mypass
code....
So I changed the perms to 0700 (user is clamav).
Now I get:
$ sudo freshclam
ERROR: Can't open/parse the config file /etc/clamav/freshclam.conf
I checked DNS resolution with this (which I found in a thread somewhere):
# host database.clamav.net
database.clamav.net is an alias for db.local.clamav.net.
db.local.clamav.net is an alias for db.other.clamav.net.
db.other.clamav.net has address 193.1.193.64
db.other.clamav.net has address 130.59.10.36
- I presume the installation can find the update site?

Is set up a postfix, dovecot + clamav server as described in the wiki. I also use the freshclam update script in /etc/cron.daily/freshclam. But my problem is i get this error message every day:
/etc/cron.daily/freshclam:
ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log). ERROR: /var/log/clamav/freshclam.log is locked by another process

When i run $ sudo freshclam I get this message ClamAV update process started at Sat Oct 9 12:21:22 2010 WARNING: Your ClamAV installation is OUTDATED!

Guessing I may have to download the package and install manually just thought I'd ask before doing that.

I installed slackware64 13.0 on my Dell D630 laptop. Recently I found a wierd network problem:
Sometimes, after couple of hours, I nearly cannot open new websites. It takes so many time to open a page. (I tried in firefox, lynx and konqueror.
But some other connection still work, such as KRDC.
I tried nslookup and dig, they all works very well, so the DNS is ok.
But ping works very slow with some url if I use the domain name. And it runs very fast with the ip of that url. So, maybe there is some problem with the DNS, or something else.
ping result is:
1) ping by domain name
2) ping by ip (same target)
Restart the network with rc.inet1 cannot fix this problem. Only I can do is reboot the computer.
May be it's a kernel(2.6.29.6) bug? Or the bug of my wireless card driver(BCM 4311)?

I have two servers complaining about ClamAV being outdated:
WARNING: Your ClamAV installation is OUTDATED!
WARNING: Local version: 0.96.1 Recommended version: 0.96.3
Doing an aptitude update says I don't have to upgrade anything. Why is this? Must ClamAV be updated manually?

On a new machine running Ubuntu 10.04.2, the freshclam program (in clamav-freshclam version 0.96.5+dfsg-1ubuntu1.10.04.2) won't do updates to the database. It fails on DNS queries. DNS works OK for other programs. The tcpdump command shows that it sends the queries to 127.0.0.1 instead of the correct DNS servers specified by /etc/resolv.conf. Of course it doesn't get an answer because it is asking the wrong IP address.
There is also a --no-dns option, but that didn't help/
Do I need to tell ot what the DNS servers are, somewhere?
Why would it query only 127.0.0.1 for DNS?

And i get this in return
Code:
Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may resolve the situation:
The following packages have unmet dependencies.
I dont get any install. and the information i have collect from people say that and install should not be stopped becuase of an depend
So as any one who is semi new would do i then tried installing the depend
Code:
And i get this in return
Code:
E: Package 'phpapi-20060613+lfs' has no installation candidate
So it look like problem after problem
Does any one know why i can not install php5-clamavlib

I am currently running Ubuntu Server 9.10 and followed this HOWTO on setting up my email server.
[url]
Everything seems to work correctly. If I look in the Maildir the emails I send to test are there.
The problem is when I try to sync my email via IMAP from my windows box (on a different network) it doesn't show any of my email nor does it deliver new email. My email app doesn't give any errors nor does the logs on the server.
How can I get it so my email syncs to windows computer? I am sure it is something really small that I am over looking but I can't seem to find it anywhere. I don't know if you need to see any of my config files but I can post them if needed.

This started happening sometime yesterday afternoon on a server that's been trouble free for years.
My Ubuntu update is scheduled to run every month on the 5th, so this was roughly 10 days after that. So it seems to me it's not update related. The only thing I've done on the server lately is update a spamassassin rule which required an amavis restart. That was done earlier in the week.
I've already reviewed issues at [url] and all the conditions are correct for the more recent How to.
I can also confirm that, in fact, /var/run/clamav/clamd.ctl does not exist.

From time to time I have to close Opera in order to regain the ability to use Totem or VLC (perhaps others). I'll explain. Normally everything is fine, but from time to time I will open Movie Player (Totem) and it will attempt to load whatever I have sent to it and it will vanish (crash). I can attempt to send anything to it and the same problem occurs (audio or video; mp3, flac, avi, &c). I can test the same problem with VLC and the same results occur (vanish/crash).
If I close Opera (and optionally restart it), I again can use Totem and VLC. I have tried merely killing Opera's plugin wrapper (thinking it was perhaps related to a plugin seizing PA), but this does nothing for the matter. (Of course killing Opera does as this is more or less the same as closing Opera.)

I'm experiencing a wierd bug. Been having it for some time now. I haven't posted about it before since its only been annoying, but not really setting me back. And I have trouble defining and explaining the bug. Today it crossed the line into actual annoyance.
The bug occurs when I'm writing, using the keyboard on my laptop. Both when I write in browsers, like when writing this post, and when I write in openoffice. So its not limited to one program. In webbrowsers what happens is that all of a sudden the browser loads the previous page in the tab. Like I told it to go one step back. In OpenOffice something similar happens. The curser jumps up in the document.
I used to have this bug when touchpad-tapping was enabled. I have a habit of drumming my thumbs on the touchpad when typing. Therefore I've disabled tapping on the touchpad. The bug is reocurring, however I have not found a way to reproduce it. It might be a key combination I accidentally hit when typing away, but I'm not sure.

Any idea if freshclam or clamav needs its own config of DNS servers?

I got my version of clamav working and it's fully updated. Problem is I can't seem to get my LibClamAV to function correctly. The output of #freshclam works But when I do: #service clamd.amavisd restart
This is the error:
LibClamAV Warning: ***********************************************************
LibClamAV Warning: *** This version of the ClamAV engine is outdated. ***
LibClamAV Warning: *** DON'T PANIC! Read http://www.clamav.net/support/faq ***

My version is updtodate and I am unsure why the error. I am using amavisd-new-2.5.2 (20070627) and Clamav 0.95.3

I can install clamav from SBo no problem, but the version is outdated. I downloaded the newer source code from clamav's site, edited the slackbuild to reflect the new version number, and rebuilt the package. But I get this following error when building.
Config files are installed in the proper places (except the file /etc/clamd.conf.rej referred to below which doesn't exist). But the binaries clamd and freshclam aren't installed anywhere.
Code:
make[2]: Leaving directory `/tmp/SBo/clamav-0.96.5/test'
Making all in clamdtop
make[2]: Entering directory `/tmp/SBo/clamav-0.96.5/clamdtop'

When I log on a root and attempt to issue the command Freshclam to upgrade the virus definitions it attempts or create a new file with a definition name. I get a message stating that the directory isnt writable. The user and group access rights are as follows:
USER = read, write, execute
Group = read, write, execute
All= read, execute.
The only way I can get around this is by applying a 777 which would be read, write and execute for all. Now, I have a group define with several user ids in it including Root.How do I connect the group with the directory/file so I dont have to apply a 777 access right to group users could issue the Freshclam command.

I've installed the Ubuntu 10.04 Server onto a PPC G4 Mac just for the experience of setting up a server. During the installation process Ubuntu couldn't auto-configure my DHCP Network. I'm using the airport card on a wireless network. How can I manually configure the network once Ubuntu is installed.

I've installed Ubuntu Server 10.10 with two network cards. One for external, and one internal.My problem is that as soon as i activate eth1 (external), i can't access the server from the internal network (eth0)
With these settings i can't reach the internal network from inside.If i disable the gateway on eth1 and enable the gateway on eth0, it works.

I have been using Ubuntu for about six months now. In my Emacs, I added CEDET but when I click the menu buttons, the options don't appear (they usually drop-down). The menu buttons for the default Emacs such as File, Edit, etc. work correctly. I had CEDET installed in my OpenSUSE and it works fine.

Problem with my Internet connection. I can't connect to the update servers. I don't know why. It's a brand new installation, not a week old yet. I can't install the support for restricted media for example. The servers won't refresh in YaST. It tells me it can't download the repomd.xml.asc.
The other problem is that some servers on the web won't load for me either.
For example, I get most of my local news from The Toronto Star, and I can't connect to it's website at all.
I can from Windows (I dual boot) but not SUSE. I don't think its a problem limited to that one website either. I am able to connect to most websites though.
This is the result of zypper repos -d
