I have a long banner, and so have tried upgrading to openssh 3.8.1p1.
I've also tried applying the patch recommended in bugzilla, but the
banner is still cut off. I don't have the option of reworking the
banner to make it smaller. Here are the sections of sshconnect2.c
that I've modified. What am I doing wrong? Thanks for your help,
Original code
358 input_userauth_banner(int type, u_int32_t seq, void *ctxt)
359 {
360 char *msg, *lang;
361
362 debug3("input_userauth_banner");
363 msg = packet_get_string(NULL);
364 lang = packet_get_string(NULL);
365 if (options.log_level > SYSLOG_LEVEL_QUIET)
366 fprintf(stderr, "%s", msg);
367 xfree(msg);
368 xfree(lang);
369 }
Patched code
input_userauth_banner(int type, u_int32_t seq, void *ctxt)
359 {
360 char *fmtbuf, *msgbuf, *lang;
361 size_t len;
362
363 debug3("input_userauth_banner");
364 msgbuf = packet_get_string(NULL);
365 lang = packet_get_string(NULL);
366 if (options.log_level > SYSLOG_LEVEL_QUIET)
367 fprintf(stderr, "%s", msg);
368 len = strlen(msgbuf);
369 fmtbuf = xmalloc(len);
370 strnvis(fmtbuf, msgbuf, len, VIS_SAFE|VIS_OCTAL);
371 fprintf(stderr, "%s", fmtbuf);
372 xfree(msgbuf);
373 xfree(fmtbuf);
374 xfree(lang);
375 }
