Trying to figure out the Perl pack function ... INSTREAMIt is mandatory to prefix this command with n or z.Scan a stream of data. The stream is sent to clamd in chunks, after INSTREAM, on the same socket on which the command was sent. This avoids the overhead of establishing new TCP connections and problems with NAT. The format of the chunk is: '' where is the size of the following data in bytes expressed as a 4 byte unsigned integer in network byte order and is the actual chunk. Streaming is terminated by sending a zero-length chunk. Note: do not exceed StreamMaxLength as defined in clamd.conf, otherwise clamd will reply with INSTREAM size limit exceeded and close the connection.NB.

I have the latest version of freshclam and clamav installed, and in the past (when I had Ubuntu 14.10) it has only run freshclam automatically a few times a day, but has not been running all the time. Now what I am finding though that if I go to Terminal and execute:sudo freshclamThat I get: ERROR: /var/log/clamav/freshclam.log is locked by another processERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).And then the only way to be able to manually run that command is to kill the freshclam process, but this is time wasting, and annoying, so I would like to fully stop freshclam from auto updating, so that I can do manual updates.So what I tried was to install clamtk, and in the Update Assistant settings I tried to set it so that I would manually install updates, and then I clicked Apply, but this seemed, even after a restart, to have no impact on how freshclam behaved.So really my question is, how can I get it so that freshclam does not automatically check for updates, or at least for it to do it a few times a day, but not always be there so that I have to kill it to run it? Or is there a way to fix clamtk so that it does it properly (I have got in touch with the developer of clamtk and he is looking into it, but does not know what the issue is)?OS Information:Description: Ubuntu 15.04Release: 15.04Package Information:ClamTk:clamtk: Installed: 5.18-1 Candidate: 5.18-1 Version table: *** 5.18-1 0 100 /var/lib/dpkg/status 5.15-1 0 500 vivid/universe amd64 PackagesClamAV:clamav: Installed: 0.98.7+dfsg-0ubuntu0.15.04.1 Candidate: 0.98.7+dfsg-0ubuntu0.15.04.1 Version table: *** 0.98.7+dfsg-0ubuntu0.15.04.1 0 500 vivid-updates/main amd64 Packages 500 vivid-security/main amd64 Packages 100 /var/lib/dpkg/status 0.98.6+dfsg-1ubuntu2 0 500 vivid/main amd64 PackagesDownload FM 104 .0 for Android
