I believe there's a way of preventing users getting a shell with '!' when running I-SQL. Anyone know about this? Any drawbacks? TIA -- Surfer!

Redefine the SHELL environment variable to (say) /bin/true for your users, before they run isql. "Surfer!" wrote: > > I believe there's a way of preventing users getting a shell with '!' > when running I-SQL. > > Anyone know about this? > > Any drawbacks? > > TIA > > -- > Surfer!
