Description of problem: It seems that telnetd/setproctitle.c sets up a string long as args + environment, then it proceeds to fill with blanks what's after the last useful chars (ie: hostname). The primary effect of this is that /proc/X/cmdline has many blanks at the end (espacially if you have a bing environment) The side effect of this is that when you do "ps ax|less", "ps ax|more" (but not simple "ps ax" or "ps ax > file") output will look like Version-Release number of selected component (if applicable): telnet-server-0.17-26 How reproducible: Always Steps to Reproduce: 1. "ps ax|less" 2. look at the output Actual Results (blank lines in output): ======== 1117 ? SW 0:00 [kjournald] 13127 ? S 0:00 in.telnetd: myhost 13128 ? S 0:00 login -- mylogin ========= Expected Results: ========= 1117 ? SW 0:00 [kjournald] 13127 ? S 0:00 in.telnetd: myhost 13128 ?
