Information.png Tip:
This page contains bits and pieces of user feedback regarding the development (and testing) of the next SME Server release based on CentOS6.
See SME_on_CentOS_6. Your feedback would be appreciated too, so please share you feedback on this page. Thanks!. Please note that all the below is unstructured user feedback. Your findings that require developers attention should be logged in our Bug Tracker


You can find our Bug Tracker here

HTTPD

yum install mod_ssl
yum install perl-suidperl
  • after fixing those two issues, we get a blank page after login on the server-manager, logs (admin_error_log) print the following error:
[Fri Jan 25 22:59:23 2013] [error] [client 127.0.0.1] Can't locate object method "host" via package "URI::_generic" at /etc/e-smith/web/common/cgi-bin/login line 162., referer: https://192.168.7.154/server-common/cgi-bin/login?redirect=1&back=http%253a%252f%252f192.168.7.154%252fserver-manager%252f
  • If we try to access the server-manager again, it's working (as we already have our cookie). It's just the redirection after the login which is broken

Squid

squid doesn't start, and the following errors are printed in /var/log/messages

2013/01/25 22:17:35| WARNING: -D command-line option is obsolete.
2013/01/25 22:17:35| ERROR: '0.0.0.0/0.0.0.0' needs to be replaced by the term 'all'.

2013/01/25 22:17:35| WARNING: Netmasks are deprecated. Please use CIDR masks instead.

2013/01/25 22:17:35| ERROR: Directive 'extension_methods' is obsolete.

So several problems here:

  • We need to remove the -D arg from /var/services/squid/run
  • We need to remove the file /etc/e-smith/templates/etc/squid/squid.conf/20ACL00all (which just contains acl all src 0.0.0.0/0.0.0.0 and is not needed anymore)
  • we need to convert acl in CIDR notation (for now, they are retrieved using esmith::NetworksDB::local_access_spec, which doesn't support cidr)
  • we need to remove /etc/e-smith/templates/etc/squid/squid.conf/35extension_methods (extensionmethods is not supported anymore as it was not usefull anymore)

clamav

  • user created during clamd installation is now clam (used to be clamav), templates for /etc/clamd.conf need to be adjusted
  • DatabaseDirectory is now /var/lib/clamav (used to be /var/clamav), templates for /etc/clamd.conf need to be adjusted
  • LocalSocket should now be /var/run/clamav/clamd.socket (use to be /var/clamav/clamd.socket), templates for /etc/clamd.conf need to be adjusted
  • Permissions on /var/spool/qpsmtpd/ (provided by smeserver-qpsmtpd) should also be adjusted (clam instead of clamav group)


qpsmtpd

Doesn't start. See Bug #7223: qpsmtp does not start

@400000005102ec023094f554 Can't locate Qpsmtpd/TcpServer.pm in @INC (@INC contains: lib /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at /usr/bin/qpsmtpd-forkserver line 13.
@400000005102ec023094fd24 BEGIN failed--compilation aborted at /usr/bin/qpsmtpd-forkserver line 13
  • We should rebuild qpsmtpd with a simple spec file change to use /usr/share/perl5/vendor_perl instead of /usr/lib/perl5/site_perl

radius

Radiusd doesn't start with this error

radiusd: Error: No log destination specified
  • To fix this error, we need to add ”-l stdout” as argument to radiusd in /var/service/radiusd/run

After that, the following error occures:

@400000005103145934920bc4 Sat Jan 26 00:25:03 2013 : Info: Starting - reading configuration files ...
@400000005103145937a239c4 Sat Jan 26 00:25:03 2013 : Error: /etc/raddb/radiusd.conf[115]: Failed to link to module 'rlm_ldap': file not found 
@400000005103145937a2c27c Sat Jan 26 00:25:03 2013 : Error: /etc/raddb/radiusd.conf[177]: Failed to load module "ldap".
@400000005103145937a2fd14 Sat Jan 26 00:25:03 2013 : Error: /etc/raddb/radiusd.conf[177]: Failed to parse "ldap" entry.
@400000005103145937a39954 Sat Jan 26 00:25:03 2013 : Error: Failed to load virtual server <default>
  • To fix this, we have to install freeradius-ldap, which is now in its own package (freeradius-ldap should be added as required by e-smith-radiusd)


syslog

upstart/sysvinit

  • in EL6, SysVinit is replaced with upstart, and upstart doesn't support rc7 runlevel. One option is to move to rc4 as default runlevel.

Bug #7217: SysVinit -> upstart Bug #7227: rc7 -> rc4l

LDAP

  • openldap-servers is not installed (missing a Requires: openldap-servers in e-smith-ldap's spec file)
  • we need to add -f /etc/openldap/slapd.conf arg when launching slapd (in /var/service/ldap/run), or it will try to convert this file the the new slapd.d style
  • schema file /etc/openldap/schema/redhat/autofs.schema is missing. In EL5, it was provided by openldap-servers. I don't think this schema is used so it may just need to be removed from the config file
  • slapd fails to start with this error:
/etc/openldap/slapd.conf: line 27: unknown directive <schemacheck> outside backend info and database definitions

console

  • kudzu has been removed from EL6, so now this bug Bug #3596: Stop using kudzu for NIC detection needs to be fixed so we can detect network interfaces.
  • Here's a code snipet which seems to work, the only thing missing is to retrieve the interface description from hwdata, for now, it just return the name 'eth0, eth1 etc… instead of the description (in esmith/ethernet.pm)
 opendir(my $dh, "/sys/class/net") or die "Couldn't open /sys/class/net: $!";
    my @nics = grep { $_ !~ m/\./ } readdir($dh);
    my $adapters = '';
    my $index = 1;
    foreach my $nic (@nics){
        next if (
            # skip loopback
            $nic eq 'lo' ||
            # skip non links
            !-l "/sys/class/net/$nic" ||
            # skip wireless nics
            -d "/sys/class/net/$nic/wireless" ||
            -l "/sys/class/net/$nic/phy80211" ||
            # skip bridges
            -d "/sys/class/net/$nic/bridge" ||
            # skip vlans
            -f "/proc/net/vlan/$nic" ||
            # skip bonds
            -d "/sys/class/net/$nic/bonding" ||
            # skip tun/tap
            -f "/sys/class/net/$nic/tun_flags" ||
            # skip dummy
            -d "/sys/devices/virtual/net/$nic"
        );
        # Now we should be left only wth ethernet adapters
        my $mac = `cat /sys/class/net/$nic/address`;
        chomp($mac);
        my $driver = `readlink /sys/class/net/$nic/device/driver`;
        $driver = `basename $driver`;
        chomp($driver);
        $adapters .= "EthernetDriver" . $index++ . "\t" . $driver . "\t" .
                     $mac . "\t" . "$nic" . "\n";
    }
    return $adapters;
