| Summary | 0002504: [Solaris] oper block with crypt hash crashes server on /oper | ||||
| Description | Basicly what summary says. My oper block with a crypt-ed pawword crashed ircd on /oper. Changed to a different encryption method removed crash. | ||||
| Steps To Reproduce | create oper block with crypted password log into server /oper user pass IRCD crash and dumps core | ||||
| Additional Information | Stock build. No added modules. | ||||
| 3rd party modules | none | ||||
|

It works fine for me, you should do a backtrace on the core and post that. |

I'm not much of a programmer. I think this is a backtrace. =) spacelab.cat.pdx.edu% gdb GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.

Try ehm: - gdb /pkgs/ircd/unreal-3.2.3/sbin/ircd /path/to/your/core/file bt - that might give a bit better backtrace (this one doesn't seem to show any symbols). This problem is probably related to running on solaris btw. |

OK this seems to give a bunch more info. If I'm reading it right I'm missing somelib or something?? spacelab.cat.pdx.edu% gdb /pkgs/ircd/unreal-3.2.3/sbin/ircd core.crypt GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.

It seems to crash in OpenSSL, but... The output of the crash you pasted is "impossible", perhaps you could remove the unrealircd binaries and .so's and re-extract the 3.2.3 source and do a ./Config && make && make install again. Don't know if it helps. If that doesn't improve the output (just paste it again and I'll take a look) or fix it then there's not much we can do except for suggesting to just use md5 instead. |

OK, I recompiled it and still got a core. The only thing that changed in my enviroment between this compile and the last one was I upgraded from gcc 3.3 to 3.4. (If you care. =) ) I'm using md5 hashes now for my oper passwords so this bug isn't affecting me. In fact my server is about ready to go production. =) Here is a backtrace from the new build. spacelab.cat.pdx.edu% gdb src/ircd core GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.
