It looks like the port respects the WITHOUT_X11 knob. I believe you get the command tshark if you don't have the GUI, which can do similar packet analysis and display in text form. I believe tshark can be used almost exactly like tcpdump for watching live traffic, but it can also read in tcpdump trace files. -- Chris Cowart Network Technical Lead Network & Infrastructure Services, RSSP-IT UC Berkeley [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iQIcBAEBAwAGBQJIyZkjAAoJEIGh6j3cHUNP1/8P/RTYTJS2pOySehsGRs+phE9Q ugPgICaIb8jPcrhUn/hSwHH4P1Bicc/QyTDP1AHKmiH0gVh2yoUu+g3Xv/1WcoTN rSEJ6bog2jvoTnYZBIxN++jgbp9oH9tedyzvLx8KnSd6MzDQkwNTlYZ2c/bbjORu ESgADDzCK2rJsYLW58G2rgDicUMnyNQWTs7B2DsNZR+E0W41QpkqKiZFlg+BBGHA FYnHnZdTk2UczH8O7ET7gKCAe+gKNzCaI5nbrA41n618qdU9bNOz6ggSNNN2jX8r Re3/rLKt44KwGVXZJjtvv4afPHQ/Ekxy8zqn/nIvvJXhtUFoC512G8nILsK0JOwi mVqlmot2kTcAcNj1DE3lkOv3cBVmEAitLuFCeYvaILpEI0142kSvIBmQ1Hvz3pta rGBrU8Ai1SdrCi6BCYdE0x7Zihx2E6t/p+JO0nyQmOtoPh3yFnndQV6L+dpAQU7J o4pl5Uq8lS1FJMWsrbFZy2IM5BJooUU3YZjj9WoQa9lDzAV3rEuhqBGK3J5wMse/ XUQWFRUYyaIFIh8Lk2O9aegrPWIj+5oEBYdBRMyLU0WcJqoQNZo+kr5M+/yPA5hJ G53ugq8JzIoy3tY6ULgADQbeHCoy2Fn8w9oDNUEunYa3VJUaZ2WfMxmJnu/RefE+ AWE8lQuVCvRuSN4Yw706 =j/ze -----END PGP SIGNATURE-----help
