What's not working with EL6
httpd
- mod_ssl is not installed (not required by any other package ?)
yum install mod_ssl
- mod_auth_tkt used to provide the perl Apache::AuthTkt module. It's not the case anymore so this module is now missing, preventing the server-manager to load
- perl-suidperl is not installed (should be added as required by e-smith-manager probably)
- 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
squid
- squid doesn't start, and the folowwing errors are printed in /var/log/messages

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
qpsmtpd
- doesn't start. See http://bugs.contribs.org/bugs/show_bug.cgi?id=7223
@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
radius
- radiusd doesn't start with this error
radiusd: Error: No log destination specified
syslog
- rsyslog is now used instead of syslog. We need to replace all occurance of syslog with rsyslog (see http://bugs.contribs.org/bugs/show_bug.cgi?id=7221)
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. See http://bugs.contribs.org/bugs/show_bug.cgi?id=7217 and http://bugs.contribs.org/bugs/show_bug.cgi?id=7227
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
- 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 http://bugs.contribs.org/show_bug.cgi?id=3596 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;

- manually running expand-templates has no effect (but the command exit with success). Templates expanded in signal-event are working
