| 13:54.44 | hittudiv | hi.. I was trying to compile curl with openssl for a busybox system. everything works fine except the program throws error that it cannot validate the certificate |
| 13:55.32 | hittudiv | can i debug the code using system's gdb? |
| 14:22.49 | mnemoc | hittudiv: you can probably debug it using the man page ;-) openssl itself doesn't come with a hardcoded list of valid CAs |
| 14:23.35 | mnemoc | play with `openssl connect` a bit |
| 14:24.21 | mnemoc | I mean, openssl s_client -connect |
| 14:24.36 | hittudiv | mnemoc, first it said it cant find ca-cert.crt |
| 14:24.45 | hittudiv | so i copied it from my system |
| 14:24.51 | hittudiv | am i doing something wrong? |
| 14:25.03 | mnemoc | strace can tell you where is it searching for the file |
| 14:25.21 | hittudiv | yes it showed. I copied it to correct path |
| 14:26.31 | hittudiv | Response = |
| 14:26.32 | hittudiv | Writing Command to the Modem Failed |
| 14:26.32 | hittudiv | Response = |

| 14:26.42 | hittudiv | * Problem with the SSL CA cert (path? access rights?) |
| 14:26.54 | mnemoc | never paste more than 3 lines on an irc channel |
| 14:27.12 | hittudiv | sorry i forgot |
| 14:27.59 | hittudiv | then i copied the cacert file from my system to the device |
| 14:28.06 | hittudiv | then it shows this error http://pastebin.com/YiTHDuNm |
| 14:29.20 | mnemoc | so your CAfile doesn't include CAs for validating that server |
| 14:29.56 | hittudiv | it has. I verified it.. |
| 14:30.16 | hittudiv | as in.. the CURL code, when compiled using gcc of my system, works perfectly |
| 14:30.40 | mnemoc | use openssl (not curl) for debugging this |
| 14:30.41 | hittudiv | so i copied /etc/ssl/certs/* to the device |
| 14:30.47 | hittudiv | ok |
| 14:31.09 | mnemoc | /etc/ssl/certs/* is for CApath, and you aren't setting that |
| 14:31.25 | mnemoc | you are using a CAfile, that means a BIG bundle |
| 14:32.03 | hittudiv | ok |
| 14:32.19 | mnemoc | also, after copying the needed .pem files you need c_rehash |
| 14:32.42 | hittudiv | i dint relly copy the binaries of openssl. I just compiled curl using openssl and copied the libcurl.so file |
| 14:32.59 | mnemoc | so older versions of openssl use md5 for the hashes in the CApath, newer versions use SHA1 |
| 14:33.16 | mnemoc | s/^so/also/ |
| 14:34.13 | hittudiv | my device vendor gave libcurl.so without ssl support.. so i tried to compile it with ssl |
| 14:34.59 | mnemoc | that's fine, but you need to understand how openssl validates certs first |
| 14:36.01 | hittudiv | any links please |
| 14:36.41 | mnemoc | http://www.openssl.org/docs/apps/s_client.html |
| 14:37.52 | hittudiv | also the device is not there with me now.. can i get something like a vm image for testing? |
| 14:37.59 | hittudiv | busybox |
| 14:44.05 | hittudiv | memoc, thanks. will debug using openssl binary |
| 14:47.20 | mnemoc | yw |

| 15:40.20 | hittudiv | how can i change time on busybox? |
| 15:40.52 | hittudiv | "date 062915302006" works on my computer but it shows 'invalid date' on the device |
| 15:41.17 | hittudiv | i can change month, date , time, but not the Year :| |
| 15:41.57 | mnemoc | try YY instead of CCYY |

| 16:51.15 | MonMotha | this is impressive. I think Dell managed to ship two computers that both had bad DVD drives |
| 16:52.09 | g1powermac | MonMotha, not as impressive as shipping two very large screen lcd tvs without realizing they shipped two. . . |
| 16:52.19 | MonMotha | g1powermac: indeed |
| 16:52.44 | g1powermac | it was definitely a bit tempting to keep both |
| 16:52.52 | MonMotha | I've been told that Dell doesn't even turn on their systems prior to shipping them. I'm guessing that is indeed the case. |
| 16:53.14 | MonMotha | apparently it's cheaper to just "support" the end users whose computers don't work rather than actually test them at the factory |

| 22:54.54 | MonMotha | Mirell: I think that's HP, at this point |

| 22:55.19 | MonMotha | I have a thinkpad |
| 22:56.05 | MonMotha | to Dell's credit, their support was decent. They're overnighting me a known-good DVD drive to replace the definitely-bad one and serve as a reference to test the other system which was exhibiting more nebulous behavior |
