Eu concordaria com o Jorge, mas não posso dizer de qual pacote /etc/services vem. Certamente não parece ser algo que seria saudável reinstalar, embora eu possa estar errado.
Editar: /etc/services vem do pacote netbase e é personalizado por outros serviços que são instalados. Você pode descobrir isso executando dlocate /etc/services (você precisa instalar dlocate primeiro).
Seguindo minha resposta no outro tópico , você poderia baixar o pacote manualmente e extrair o arquivo. Ou "arrisque" com sudo apt-get --reinstall --purge install netbase . Eu digo risco apenas porque o primeiro método é muito mais seguro.
Para não piorar as coisas, aqui está um arquivo de serviços de uma atualização "quase virgem" para o Maverick:
# Network services, Internet style
#
# Note that it is presently the policy of IANA to assign a single well-known
# port number for both TCP and UDP; hence, officially ports have two entries
# even if the protocol doesn't support UDP operations.
#
# Updated from http://www.iana.org/assignments/port-numbers and other
# sources like http://www.freebsd.org/cgi/cvsweb.cgi/src/etc/services .
# New ports will be added on request if they have been officially assigned
# by IANA and used in the real-world or are needed by a debian package.
# If you need a huge list of used numbers please install the nmap package.
