Re: [squid-users] Getting config from running squid

Henrik,

I don't have any experience with gdb. I get the following when I try
your suggestion:

phobos:~$ gdb /u1/squid/bin/squid
GNU gdb 4.18

This GDB was configured as "i686-pc-linux-gnulibc1"...
(gdb) tbreak cachemgrStart
Breakpoint 1 at 0x8057599: file cache_manager.c, line 199.
(gdb) continue
The program is not being run.

Can you tell me what this means, please.

Thanks,
Wayne
