Barnet have completed the signing of former Everton, Sunderland and Reading midfielder John Oster on a free transfer.
The Wales international, 33, was released by Doncaster over the summer.
Oster told the club's official website: "I'm just delighted that I've signed here. I'm raring to go.
"I just want to play football and Barnet showed great interest in me. I spoke to Mark Robson and he wants to do things the right way by playing good football and he feels the results will come."
Robson said: "I'm delighted to have signed a player of John's quality and his much-needed experience.
"Having played in the Premiership and Championship, including last season for Doncaster Rovers, this is a major coup for Barnet FC."
