Hi!

Please, test if the call /usr/bin/clamscan is fine!

if not, use:

whereis clamscan

for found this executable.

Best regards,

Fegor

Also, test from command line using the same user as the Alfresco process

I have installed the amps in alfresco 5.2 and keep the following configuration in alfviral.properties file

alfviral.mode=COMMAND

alfviral.command.exec=/usr/bin/clamscan

when I run the clamscan command in terminal,it is working perfectly.

but when I have tried to run the command through java code,it is giving the exit code 127 which means that the command is not found

I have the following code in CommandScan.java class

ProcessBuilder pb = new ProcessBuilder(this.command);

Process process = pb.start();

res = process.waitFor();

logger.debug(" ++++++the value of res is++++++++"+res);

and when I have uploaded a file of mimetype application/x-dosexec,I got the following logs

2018-03-07 19:12:38,753 DEBUG [security.antivirus.CommandScan] [http-apr-8080-exec-10] ++++++the value of res is++++++++127

I am surprised that logs are showing that the command is not found because when I have directly run the clamscan on a file,it is working perfectly and showing that the file is infected if the file is infected and clean if the file is not infected.

Can anyone tell me why the clamscan command is giving the value 127(command not found) through the java class but running perfectly through the terminal.

Please, in java code insert:

logger.debug(" ++++++ The value of command is: " + this.command);

And return this info.

And, as Mkel say, which user runs Alfresco?

And finally, the best method to use Alfviral is through ICAP protocol 😉

ayushi_agrahari — Fri, 09 Mar 2018 13:32:58 GMT

when I put this

logger.debug(" ++++++ The value of command is: " + this.command);

the logs are

2018-03-09 19:00:06,535 DEBUG [security.antivirus.CommandScan] [DefaultScheduler_Worker-10] ++++++ the value of command is[/usr/bin/clamscan, /home/alfresco_installation/Alfviral/alf_data/contentstore/2018/3/9/14/46/aeaa46c1-9af5-4d1d-9750-24656ad3da5b.bin]

Re: clamscan command from the java program gives the exit code 127

fegor — Fri, 09 Mar 2018 13:49:33 GMT

Hi!

One, exist the bin file?, '/home/alfresco_installation/Alfviral/alf_data/contentstore/2018/3/9/14/46/aeaa46c1-9af5-4d1d-9750-24656ad3da5b.bin'

Two, can you prove without path?, only with clamscan.

Best regards,

Fegor

Re: clamscan command from the java program gives the exit code 127

ayushi_agrahari — Fri, 09 Mar 2018 14:48:45 GMT

Yes,the bin file /home/alfresco_installation/Alfviral/alf_data/contentstore/2018/3/9/14/46/aeaa46c1-9af54d1d-9750-24656ad3da5b.bin exists and the clamscan is working directly properly and returning the correct value.

But not through the /usr/bin/clamscan command from java class

And secondly,I don't understand what do u mean by proving without the path.

Regards

Ayushi

Hi!

Without path is:

alfviral.command.exec=clamscan

On doing

alfviral.command.exec=clamscan

it still is showing the status as 127 means that the command is not found.

The logs are

the value of command is[clamscan, /home/alfresco_installation/Alfviral/alf_data/contentstore/2018/3/6/18/3/d66b45ad-992e-4154-b844-c1b8e0cdb03e.bin]
2018-03-12 13:40:00,338 DEBUG [security.antivirus.CommandScan] [DefaultScheduler_Worker-2] ++++++the value of res is++++++++127

but on directly running the command,the command is working perfectly.

the output is
