4PSA SpamGuardian, Plesk 9 and syntax error near unexpected token ‘>>’

April 8th, 2009 — Linux, Plesk

After Plesk upgrade we had to upgrade SpamGuardian too, but the scripts from the rpm contains syntax errors and the package can’t be installed:

[root@andromeda tmp]# rpm -Uvh --force 4psa-sguardian-psa9-3.5.0-090305.01.rhel5.i386.rpm
Preparing... ########################################### [100%]
1:4psa-sguardian-psa9 ########################################### [100%]
/var/tmp/rpm-tmp.42581: line 315: syntax error near unexpected token `>>'
/var/tmp/rpm-tmp.42581: line 315: ` echo >> >> /etc/sguardian/sguardian.conf'

The solution is to install the rpm without running PRE/POST install scripts:

[root@andromeda tmp]# rpm -Uvh --force --noscripts 4psa-sguardian-psa9-3.5.0-090305.01.rhel5.i386.rpm

Then we can extract scripts with mc (midnight commander), or rpm -qp –scripts and run them separately after correcting the syntax errors (comment lines containing “>> >>” string):

[root@andromeda scripts]# sh PREIN 
 
[...]
 
[root@andromeda scripts]# sh POSTIN

Munpack – File size limit exceeded

April 7th, 2009 — Linux, Plesk

We alreay know how to extract files from Plesk backup with mpack, but if you do receive “File size limit exceeded” error, it can be from the following reasons:

  • Your file system doesn’t have LFS (large file support) support
  • OS limits (limits on the system resources imposed by your administrator)
  • mpack is not compiled with LFS

Check that your filesystem supports files bigger than 2GB (create a test file with “dd” command).

[vitalie@silver ~]$ dd if=/dev/zero of=test.bin bs=1G count=3 # create 3GB file

Then check your file size limits with ulimit command:

[vitalie@silver ~]$ ulimit -a | grep '^file size'
file size               (blocks, -f) unlimited

You can adjust limits from /etc/security/limits.conf, read file comments on how to do it, or read this article:
http://www.cyberciti.biz/faq/file-size-limit-exceeded-error-under-linux-and-solution/

If none above limits you, then the problems comes from mpack, it doesn’t have suport for large files (>2GB).

The guys from the Plesk recommends to grep the backup file, to find begin and end of the file in archive:

This solutions is not appropriate for large backup files, we’ll just recompile mpack to support large files.

Grab mpack’s RPM source from the Dag’s repository
http://dag.wieers.com/rpm/packages/mpack/mpack-1.6-2.rf.src.rpm

install it:

[vitalie@silver ~]$ rpm -ivh mpack-1.6-2.rf.src.rpm
[...]

Then modify mpack.spec and add the following code after “%build”:

export CFLAGS="-D_FILE_OFFSET_BITS=64"

Then rebuild the package and install it:

[vitalie@silver ~] rpm -ba mpack.spec
[...]
[vitalie@silver ~] rpm -Uvh --force mpack-1.6-3.rf.i386.rpm
[...]
